The options are: - -DEBUG (origin: U C Berkeley) - enables the -d command line option, and allows SIGUSR1 to increment -and SIGUSR2 to clear the internal variable "debug", which in turn controls -hundreds of fprintf()'s out to /usr/tmp/named.run. - you probably want this. it makes the binary bigger but not slower (or -at least not much slower), but SIGUSR[12] are the only way you'll track down -misconfigured name servers that hose you down with billions of bogus requests. - you may need this, it is on by default. - -ALLOW_T_UNSPEC (origin: MIT Project Athena) - enables the "unspec" RR type for ancient Athena software that does not -know about TXT RR's. - you probably do not care about this, it is off by default. - -ALLOW_UPDATES (origin: Mike Schwartz, University of Washington) - enables "dynamic updates", described in "doc/DynamicUpdate". this lets -you update named's in-memory database on the fly if you have the right client. -there is absolutely no security around this; if you enable it, anyone who can -reach your server can update your database. - this code doesn't compile any more and will be removed shortly. - -INVQ (origin: U C Berkeley, with #ifdef's by Paul Vixie) - enables "inverse queries", which in all of the internet only one -client ever uses: ancient nslookup. if you build named with INVQ defined, -you get the time-honored behaviour of supporting this whole class of queries -for no real purpose other than to waste a few hundred kilobytes of your -memory and about 3% of named's total CPU time. if you build with INVQ -undefined, old nslookups will not be able to reach your server in their -startup phase, and you will have to use the "server" command after it fails -over to some other server, or use "nslookup - 0" to get in from the shell. - if you need to support old nslookups try "options fake-iquery" -instead of enabling this option. - you probably do not want this. - -DSTORAGE (origin: U C Berkeley, with #ifdef's by Paul Vixie) - enables a malloc-debugger that checks for overruns on both ends of -each allocated block of memory. used when debugging since C has no bounds -or type checking. - you probably do not want this, it is off by default. - -DMALLOC (origin: Paul Vixie of Digital) - enables a malloc-debugger that traces all allocated blocks of memory -such that SIGIOT's output (see STATS option) includes a list of all mallocs -in the program, how many times each has been called, how many blocks of memory -allocated by that malloc are not yet free, and how many bytes they use up. -under each one will be a list of each free/realloc that has deallocated a block -of that malloc's memory, and how many times it has done so. - this is extremely helpful for finding memory leaks. as such, you -probably do not want this unless you are debugging named. - you probably do not need this, it is off by default. - -XFRNETS (origin: Paul Vixie of Digital) - enables the "xfrnets" command in named.boot. this has the same -syntax as "forwarders" and "sortlist" -- that is, a list of dotted quads. -each one is a network (16.0.0.0 and 130.180.0.0 are examples) or a host. -if you put any xfrnets commands into your named.boot, then zone transfers -will only be honored if they come from inside one of the specified -networks. this is very useful if you want to keep people outside from -being able to trivially map your entire network, but it doesn't stop them -from iterating so it's more annoying than secure. - this feature was once called "tcplist" out of ignorance on my part, -but with advice from phil almquist i decided to rename it "xfrnets" and make -it only control zone transfers -- previously it controlled all TCP connections -which made certain TCP-only resolvers unable to use our servers. the "tcplist" -syntax still works; it is a synonym for "xfrnets". - it is also nice if you want to keep the outside world from making your -nameserver fork and swap trying to do unauthorized zone transfers. if you have -large zone files or use BIND for TXT records you will find this useful. - you probably want this, it is on by default. - -PID_FIX (origin: Don Lewis of Harris) - tells named that if it starts up but can't keep going because another -nameserver is already running (and sitting on the server port), it should -put the /etc/named.pid (/var/run/named.pid) file back the way it found it. - you probably want this, it is on by default. - -FWD_LOOP (origin: Don Lewis of Harris) - tells named that if you list any of your own IP addresses in a -"forwarders" command in your named.boot file, you should be scolded. - you probably want this, it is on by default. - -NO_GLUE (origin: Don Lewis of Harris, and Andrew Partan of UUNET) - tells named-xfer that incoming zone transfers should be checked -for "glue" that comes from a zone outside the zone being transfered, and -comment this garbage out in the zone file so that when named reads in the -zone file after named-xfer exits, the garbage will not be entered into the -memory-resident database. - also tells named that when it is performing an outgoing zone -transfer, it should not send any of these "glue" records. - you definitely want this, it is on by default. - -BOGUSNS (origin: Piet Beertema of EUNet) - enables the "bogusns" command in named.boot. this has the same -syntax as forwarders and sortlist. any NS RR's that come in whose addresses -are on the list of "bogusns" addresses will be ignored. this is the last -resort when someone is bogusly advertising themselves as a root server. - just in case, though you won't use it often. - you probably want this, it is on by default. - -QRYLOG (origin: Bryan Beecher of UMich) - enables "query logging", such that SIGWINCH toggles tracing of all -incoming queries. the trace is sent to syslog, and is huge, but when you -need this you will need it bad and it does not slow named down or make it -larger. - If you define QRYLOG you may also start up named in query logging -mode by using the -q flag. If you do so you will probably want to analyze -the logs produced, the dnsstats and lamers scrips (in the contrib/umich -and contrib/lamers directories) will do it for you. - you probably want this, it is on by default. - -LOGFAC (origin: various people) - If you start up named with the -q flag you will be logging -large amounts of data, and probably will not want them logged to the -default logging facility, which is LOG_DAEMON. You will want to -redefine LOGFAC, presumably to LOC_LOCALn (0 <= n <= 7). Remember to -modify /etc/syslog.conf appropriately. - This only works on a system with a modern syslogd. - as such, it is on by default. - -YPKLUDGE (origin: Piet Beertema of EUNet) - certain versions of NIS/YP are capable of using the DNS for names -that cannot be found in the YP servers. of these, certain versions can't -tell the difference between a dotted quad and a domain name, and they send -queries to the DNS for dotted quads as if they were domain names. if your -named does not do anything special with these queries, they will end up -getting forwarded to other servers, effectively hosing all of you down with -endless useless network traffic. YPKLUDGE enables some checking in named -that lets it catch these bogus queries and send back immediate errors. - If you run "ypserv -i" you definitely want this, as a malconfigured -NIS server can cause DNS "flood" queries otherwise. Trust me. - this is off by default. - -TRACEROOT (origin: pma@cnd.hp.com and Bryan Beecher of UMich) - enables some checking in named for bogus root nameservers. This -code has been in use at U-M for years, so it is pretty well tested, plus we -have never been burned by the "bogus root NS scares" that have plagued the -DNS off and on. - this feature people will very much want to use, it is on by default. - -LOCALDOM (origin: Berkeley) - if set, the "domain" directive is recognized in the named.boot file. -this causes us to retry queries with the specified domain appended to the -name if the first lookup fails. this is a very bad idea since a given name -server will often be used by clients in more than one domain -- a name server -should _not_ make any presumptions as to the "home domain" of a requestor. - you almost certainly do not want this, it is off by default. - -SLAVE_FORWARD (origin: pma@sdd.hp.com) - if set, "slave" servers behave in an arguably more-correct way. this -is an experimental addition to BIND 4.9 that causes slaves to time out queries -in 60/N seconds where N is the number of forwarders defined. previously a -query would time out almost immediately, which caused a lot of unnecessary -network traffic. - you probably want this, it is on by default. - -FORCED_RELOAD (origin: pma@sdd.hp.com) - if set, then when a HUP signal is received, all secondary zones are -scheduled for serial-number comparison with the primaries. this has the effect -that if you HUP your server, it will refresh any zones which have changed, -even if those zones' refresh times have not been reached. - you probably want this, it is on by default. - -WANT_PIDFILE (origin: berkeley, parameterized by arc@sgi) - if set, a file called named.pid will be created in /etc or /var/run -when the name server has started. this file can be used to send signals to -BIND, as in "kill -HUP `cat /etc/named.pid`". - unless you are only on an SGI (where killall(1M) makes the pid file -unnecessary); - you probably want this, it is on by default. - -DOTTED_SERIAL (origin: berkeley; parameterized by vixie) - if set, allows a somewhat arcane n.m syntax in the serial number -field of an SOA. this is officially deprecated for 4.9; you should use -straight integer values and find an encoding that does not depend on -scaled-integer pseudodecimals. i suggest YYYYMMDDnn where YYYY is the -four-digit year, MM is the two-digit month, DD is the two-digit day-of-month, -and nn is a daily version number in case you change your serial number more -than once in a day. this encoding will overflow in the year 4294 gregorian. - you almost certainly do not want this, but if you have old zone files -lying around and you don't want to think your way through converting their -serial numbers, this deprecated behaviour is available. - graciously, it is on by default. - -SENSIBLE_DOTS (origin: kagotani@cs.titech.ac.jp; parameterized by vixie) - if set, changes the semantics of an "n.m" serial number from - n*10^(3+int(0.9+log10(m))) + m -to - n*10000+m - if you are using DOTTED_SERIAL in spite of its deprecated status, -and you are interested in a more predictable and sensible interpretation of -dotted numbers, then you probably want this. - it is off by default. - -VALIDATE (origin: USC/ISI) - enables a validation procedure to provide some security in an -otherwise insecure environment. Any RRs are accepted from a server only if -the server is authoritative over that domain. We consider a server -authoritative (for validation purposes) for even the sub-domains that it has -delegated to others. RRs are validated against the data we have in cache -already. Invalid records are neither cached nor returned. - it is off by default because it is hopeless, and the code will all -be ripped out of BIND in the near future. - -NCACHE (origin: USC/ISI) - enables negative caching. We cache only authoritative NXDOMAIN or -authoritative NOERROR with zero RR count. Non-authoritative NXDOMAIN answers -now contain NS records in the authority section. Non-authoritative NOERROR -responses have no authority or additional records to differentiate them from -referrals. They are cached for NTTL secs (currently 10 minutes) and are timed -out when the ttl expires. - you probably want this, it is on by default. - -RESOLVSORT (origin: marka@syd.dms.csiro.au) - enable sorting of addresses returned by gethostbyname. Sorting order -is specified by address/netmask pairs. This enables a host to override the -sortlist specified in the nameserver. - you probably want this, it is on by default. - -STUBS (origin: marka@syd.dms.csiro.au) - enable transfer and loading of NS records only for a zone. -still experimental. it won't hurt to enable it, but it may not work perfectly -so using it could lead to some confusion. - you probably don't care, it is on by default. - -SUNSECURITY (origin: rossc@ucc.su.oz.au) - enable checking of PTR records in gethostbyaddr() to detect -spoofing. Forced on SunOS 4 shared library as rlogin etc. depend on this. - you should probably not set this by hand. - -SECURE_ZONES (origin: gshapiro@guest.wpi.edu) - enables support for secure zones. This restricts access to -information in the zone according to the information found in the -secure_zone TXT RR found in the zone. If none is found, the zone is -world-readable. For information on the format of the secure_zone TXT -RR, see the Name Server Operations Guide for BIND. - you probably want this, it is on by default. - -ROUND_ROBIN (origin: Marshall Rose of TPC.INT) - if set, causes the databuf list in a namebuf to be rotated by one -slot after each access to it. this has the effect that if multiple RR's -of a given type are present, they will be given in "round robin" order -instead of always being given in the same order. - you probably want this, it is on by default. - -ADDAUTH (origin: marka@syd.dms.csiro.au) - if set, cause NS and glue A records to be returned with authoritative -answers. this causes slightly larger replies but less DNS traffic overall. - unless you have Mac's with an older version of Mac/TCP; - you probably want this, it is on by default. - -RFC1535 (origin: paul@vix.com) - if set, the resolver's default "search" list will be just the entire -"domain" name rather than the sliding window it had before 4.9.2. this will -make the default search list shorter, so folks who are saying "domain a.b.c" -and relying on the implicit "search a.b.c a.b c" will miss "a.b" and "c". - this option is on for compatibility with RFC 1535. - you should NOT turn it off, it is on by default. - -GEN_AXFR (origin: mark@comp.vuw.ac.nz, tytso@ATHENA.MIT.EDU, gdmr@dcs.ed.ac.uk) - if set, allows specification of zones in classes other than "IN" in -the named.boot file. Allows an optional "/class" on the "primary" and -"secondary" directives. Also fixes zone transfers so only data in the class -requested is transfered. - you probably want this, it is on by default. - -DATUMREFCNT (origin: mark andrews) - you want this. it will not be optional in future releases. - -LAME_DELEGATION (origin: don lewis; reworked by bryan beecher and don lewis) - this will detect the condition where some other server has told you -that a given set of servers is authoritative for some domain, and at least -one of those "delegated" servers disagrees (i.e., answers non-authoritatively). - you probably want this, it is on by default. - -LAME_LOGGING (origin: don lewis) - enable logging of lame delegations and set the log level - you may want this, it is on by default. - -RETURNSOA (origin: mark andrews) - This allows negative caching to work. Without this, older -pre-4.9.3 nameservers will not accept -ve cached anwsers. We actually -store the SOA record from the authority section rather that what was -requested because it is the existence of the NXDOMAIN that matters not -the type of data. The zone of the SOA record is tagged to the end of -the SOA record to allow it to be reconstructed. - You probably DO NOT WANT THIS, it's experimental and dangerous. - it is off by default. - -CLEANCACHE (origin: mark andrews) - Bind consumes memory without bound without this option. This -patch allows bind to periodically remove any stale entries in the -cache. Bind's memory usage should stabilize after approximately 1 day of -operation, as most TTL's are <= 1 day. Without this option stale entries -are only removed when they are looked up. - You probably want this, it is on by default. - -PURGE_ZONE (origin: mark andrews) - Various junk below a zone tends to hang around and corrupt future -zone data if a zone grows deeper. PURGE_ZONE will remove all traces of or -data which could be part of zone before loading a new one. - You probably want this, it is on by default. - -STATS (origin: Paul Vixie) - Named's internal statistics can take a fair amount of memory and -if you aren't interested in looking at these numbers you should disable -the feature. Future versions may require this. - You probably want this, it is on by default. - -RENICE (origin: bp@deins.informatik.uni-dortmund.de) - if set, the process priority of the AXFR subprocesses is changed to -"normal". If you are planning to raise the priority of the main nameserver -process, you will use this. - You probably want this, it is on by default. - -GETSER_LOGGING (origin: Paul Vixie) - if set, errors that occur during the fetch of serial numbers for zone -transfer consideration will be syslog()'d. this can lead to a lot of logging, -but is very helpful if you don't know why a zone isn't transfering. - You may not want this, but it is on by default. - -SHORT_FNAMES (origin: pma@sdd.hp.com) - on systems whose file names can only be 14 characters long, the temp -files created by named-xfer need to be constructed somewhat differently. this -should probably become the default since it is harmless. - you probably don't care one way or the other, it is off by default. - -XSTATS (origin: Benoit.Grange@inria.fr) - if set, the name server keeps more STATS about requests -received, and logs to syslog total counters from time to time. If you -aren't interested in looking at these numbers you should not enable -the feature. Requires STATS. - You may want this, but it is off by default. - -BIND_NOTIFY (origin: paul@vix.com) - experimental at this time; an internet draft is circulating. this -option informs slaves ("secondary" servers in BIND's erroneous terminology) -instantly when the master (primary, or another slave) loads a new zone. it -works fine and seems to cause no problems with slaves that don't support it, -but it does not implement the current internet draft (it lacks some necessary -delays) and causes a lot of extra syslog traffic, especially at startup. if -you don't mind running code that will absolutely NOT be compatible with the -eventual standard when the RFC is released, go ahead and turn this on. - vendors should not enable this in versions shipped to customers. - You will want this when it becomes compliant, it is off by default. - -LOC_RR (origin: ckd@kei.com) - incorporates support for the (RFC 1876) LOC RR type. - You may want this, it is on by default. - -SORT_RESPONSE (legacy) - should responses be sorted in what the server considers an optimal -order for the client? this is on by default but it does very little good. - -## ++Copyright++ 1989 -## - -## Copyright (c) 1989 -## The Regents of the University of California.

One is the user interface called the -\fIresolver\fP -which consists of a group of routines that reside in the C library -\fI/lib/libc.a\fP. -Second is the actual server called \fInamed\fP. -This is a daemon that runs in the background and services queries on a -given network port. The standard port for UDP and TCP is specified in -\fI/etc/services\fP. -.sh 2 "Resolver Routines in libc" -.pp -When building your 4.3BSD system you may either -build the C library to use the name server resolver routines -or use the host table lookup routines to do host name and address resolution. -The default resolver for 4.3BSD uses the name server. Newer BSD systems -include both name server and host table functionality with preference given -to the name server if there is one or if there is a \fI/etc/resolv.conf\fP -file. -.pp -Building the C library to use the name server changes the way -\fIgethostbyname\fP\|(3N), \fIgethostbyaddr\fP\|(3N), and -\fIsethostent\fP\|(3N) do their functions. The name server renders -\fIgethostent\fP\|(3N) obsolete, since it has no concept of a next line in -the database. These library calls are built with the resolver routines -needed to query the name server. -.pp -The \fIresolver\fP contains functions that build query -packets and exchange them with name servers. -.pp -Before building the 4.3BSD C library, set the variable \fIHOSTLOOKUP\fP -equal to \fInamed\fP in \fI/usr/src/lib/libc/Makefile\fP. You -then make and install the C library and compiler and then compile the rest -of the 4.3BSD system.

Note that your vendor's \fIresolver\fP -may be out of date with respect to the one shipped with \s-1BIND\s+1, and that -you might want to build \s-1BIND\s+1's resolver library and install it, and -its include files, into your system's compile/link path so that your own -network applications will be able to use the newer features. diff --git a/contrib/bind/doc/bog/files.me b/contrib/bind/doc/bog/files.me deleted file mode 100644 index ae755ff2fd1c..000000000000 --- a/contrib/bind/doc/bog/files.me +++ /dev/null @@ -1,1150 +0,0 @@ -.\" ++Copyright++ 1986, 1988, 1995 -.\" - -.\" Copyright (c) 1986, 1988, 1995 -.\" The Regents of the University of California.

Newer designs assume that the -resolver library will append its own idea of a ``default domain'' to any -unqualified names. Though the name server can still be compiled with -support for the \fIdomain\fP directive in the boot file, the default is to -leave it out and we strenuously recommend against its use. If you use this -feature, clients outside your local domain which send you requests about -unqualified names will have the implicit qualification of your domain rather -than theirs. The proper place for this function is on the client, in their -\fB/etc/resolv.conf\fP (or equivalent) file. Use of the \fIdomain\fP -directive in your boot file is strongly discouraged. -.sh 3 "Directory" -.pp -The \fIdirectory\fP directive specifies the directory in which the name server -should run, allowing the other file names in the boot file to use relative path -names. There can be only one \fIdirectory\fP directive and it should be given -before any other directives that specify file names. -.(b l -.ta 0.5i +\w`secondary `u +\w`berkeley.edu `u +.5i +.5i -\fIdirectory /var/named\fP -.)b -.re -If you have more than a couple of named files to be maintained, you may wish -to place the named files in a directory such as /var/named and adjust the -directory command properly. The main purposes of this command are to make -sure named is in the proper directory when trying to include files by -relative path names with $INCLUDE and to allow named to run in a location -that is reasonable to dump core if it feels the urge. -.sh 3 "Primary Service" -.pp -The line in the boot file that designates the server as a primary master server -for a zone looks as follows: -.(b l -.ta 0.5i +\w`secondary `u +\w`berkeley.edu `u +.5i +.5i -\fIprimary Berkeley\fP\fB\|.\|\fP\fIEdu ucbhosts\fP -.)b -.re -The first field specifies that the server is a primary one for the zone -stated in the second field. -The third field is the name of the file from which the data is read. -.pp -The above assumes that the zone you are specifying is a class \fIIN\fP -zone.

A \fIforwarder\fP is another -server capable of processing recursive queries that is willing to try -resolving queries on behalf of other systems. The \fIforwarders\fP -command specifies forwarders by internet address as follows: -.(b l -\fIforwarders \fI128\fP\fB.\fP\fI32\fP\fB.\fP\fI0\fP\fB.\fP\fI10 \fP\fI128\fP\fB.\fP\fI32\fP\fB.\fP\fI0\fP\fB.\fP\fI4\fP -.)b -.re -There are two main reasons for wanting to do so. First, some systems may -not have full network access and may be prevented from sending any IP -packets into the rest of the Internet and therefore must rely on a forwarder -which does have access to the full net. The second reason is that the -forwarder sees a union of all queries as they pass through its server and -therefore it builds up a very rich cache of data compared to the cache in a -typical workstation name server. In effect, the \fIforwarder\fP becomes a -meta-cache that all hosts can benefit from, thereby reducing the total -number of queries from that site to the rest of the net. -.pp -The effect of ``forwarders'' is to prepend some fixed addresses to the list -of name servers to be tried for every query. Normally that list is made up -only of higher-authority servers discovered via \fINS\fP record lookups for -the relevant domain. If the forwarders do not answer, then unless the -\fIslave\fP directive was given, the appropriate servers for the domains -will be queried directly. - -.sh 3 "Slave Servers" -.pp -Slave mode is used if the use of forwarders is the only possible way -to resolve queries due to lack of full net access or if you wish to prevent -the name server from using other than the listed forwarders. -Slave mode is activated by placing the simple command -.(b l -\fIoptions forward-only\fP -.)b -in the bootfile. If this option is used, then you must specify forwarders. -When in slave mode, the server will forward each query to each of the -forwarders until an answer is found or the list of forwarders is exhausted. -The server will not try to contact any remote name server other than those -named in the \fIforwarders\fP list. -.pp -So while \fIforwarders\fP prepends addresses to the ``server list'' for each -query, \fIoptions forward-only\fP causes the ``server list'' to contain -\fIonly\fP those addresses listed in the \fIforwarders\fP declarations. -Careless use of the \fIoptions forward-only\fP directive can cause really -horrible forwarding loops, since -you could end up forwarding queries only to some set of hosts which are also -slaves, and one or several of them could be forwarding queries back to you. -.pp -Use of the \fIoptions forward-only\fP directive should be considered very -carefully. Note that this same behaviour can be achieved using the deprecated -directive, \fIslave\fP. - -.sh 3 "Nonrecursive Servers" -.pp -\s-1BIND\s+1's separation of authoritative (zone) and nonauthoritiative (cache) -data has always been somewhat weak, and pollution of the former via the latter -has been known to occur. One way to prevent this, as well as to save memory on -servers carrying a lot of authoritative data (e.g., root servers) is to make -such servers ``nonrecursive.'' This can be achieved via the directive -.(b l -\fIoptions no-recursion\fP -.)b -in the bootfile. A server with this option enabled will not attempt to fetch -data to help answer queries \(em if you ask it for data it does not have, it -will send you a referral to a more authoritative server or, if it is itself -authoritative for the zone of the query, it will send you an negative answer. -.pp -A nonrecursive server can be named in an \s-1NS\ RR\s+1 but it cannot be listed -in the \fIresolv.conf\fP file. - -.sh 3 "Query Logging" -.pp -If the file system containing your \fIsyslog\fP file has quite a bit of space, -you can consider using the -.(b l -\fIoptions query-log\fP -.)b -directive in your bootfile. This will cause your name server to log every -query it receives, which when combined with a Perl or \s-1AWK\s+1 script to -postprocess the logs, can be a useful management tool. - -.sh 3 "Inverse Query Pseudosupport" -.pp -\s-1BIND\s+1 by default does not support inverse queries, and this has been -known to cause problems for certain microcomputer operating systems and for -older versions of \s-1BIND\s+1's \fInslookup\fP tool. You may decide that -rather than answering with ``operation not implemented,'' \fInamed\fP should -detect the most common inverse queries and answer them with bogus information. -It is better to upgrade your clients to stop depending on inverse queries, but -if that is not possible, you should use the -.(b l -\fIoptions fake-iquery\fP -.)b -directive in your bootfile. \fINOTE:\fP the responses are in fact bogus, in -that they contain \s-1ISO\s+18859 square brackets (\fB[\fP and \fB]\fP), so -your clients will not be able to do anything useful with these responses. It -has been observed that no client ever did anything useful with real inverse -query responses, either. - -.sh 3 "Setting Name Server Limits" -.pp -Some name server operations can be quite resource intensive, and in order to -tune your system properly it is sometimes necessary to change \s-1BIND\s+1's -internal quotas. This is accomplished via -.(b l -\fIlimit <name> <value>\fP -.)b -directives in the bootfile. Limits, and their default values, are as follows: -.(b I -\fIlimit transfers-in 10\fP -.)b -This is the number of simultaneous \fInamed-xfer\fP processes \s-1BIND\s+1 is -willing to start. Higher numbers yield faster convergence to primary servers -if your secondary server has hundreds or thousands of zones to maintain, but -setting this number too high can cause thrashing due to starvation of resources -such as network bandwidth or swap space. \fINOTE:\fP this limit can also be -expressed via the deprecated directive \fImax-fetch NN\fP. -.(b I -\fIlimit transfers-per-ns 2\fP -.)b -This is the number of simultaneous \fInamed-xfer\fP processes \s-1BIND\s+1 is -willing to initiate \fIto any given name server\fP. In most cases, you should -not need to change it. If your secondary server is pulling hundreds or -thousands of zones from a single primary server, increasing -\fItransfers-per-ns\fP may speed convergence. It should be kept as -small as possible, to avoid causing thrashing and resource starvation -on the primary server. -.(b I -\fIlimit datasize <system-dependent>\fP -.)b -Most systems have a quota that limits the size of the so-called ``data -segment,'' which is where \s-1BIND\s+1 keeps all of its authority and cache -data. \s-1BIND\s+1 will behave suboptimally (perhaps even exiting) if it runs -up against this quota. If your system supports a system call to change this -quota for a given process, you can ask \s-1BIND\s+1 to use that system call -via the \fIlimit datasize NN\fP directive. The value given here may be scaled -by postfixing \fIk\fP for 1024X, \fIm\fP for (1024^2)X, and \fIg\fP for -(1024^3)X. In 1995, the root servers all use \fIlimit datasize 64m\fP. - -.sh 3 "Zone Transfer Restrictions" -.pp -It may be the case that your organization does not wish to give complete -lists of your hosts to anyone on the Internet who can reach your name servers. -While it is still possible for people to ``iterate'' through your address -range, looking for \fIPTR\fP records, and build a list of your hosts the -``slow'' way, it is still considered reasonable to restrict your export of -zones via the zone transfer protocol. To limit the list of neighbors who -can transfer zones from your server, use the \fIxfrnets\fP directive. -.pp -This directive has the same syntax as \fIforwarders\fP except that you can -list network numbers in addition to host addresses. For example, you could -add the directive -.(b l -\fIxfrnets 16.0.0.0\fP -.)b -.re -if you wanted to permit only hosts on Class A network number 16 to transfer -zones from your server. This is not nearly granular enough, and a future -version of \s-1BIND\s+1 will permit such access-control to be specified on a -per-host basis rather than the current per-net basis. Note that while -addresses without explicit masks are assumed by this directive to be networks, -you can specify a mask which is as granular as you wish, perhaps including -all bits of the address such that only a single host is given transfer -permission. For example, consider -.(b l -\fIxfrnets 16.1.0.2&255.255.255.255\fP -.)b -which would permit only host \fI16.1.0.2\fP to transfer zones from you. Note -that no spaces are allowed surrounding the ``\fI&\fP'' character that -introduces a netmask. -.pp -The \fIxfrnets\fP directive may also be given as \fItcplist\fP for -compatibility with interim releases of \s-1BIND\s+1 4.9. - -.sh 3 "Sorting Addresses" -.pp -If there are multiple addresses available for a name server which \s-1BIND\s+1 -wants to contact, \s-1BIND\s+1 will try the ones it believes are ``closest'' -first. ``Closeness'' is defined in terms of similarity-of-address; that is, -if one address is on the same \fIsubnet\fP as some interface of the local host, -then that address will be tried first. Failing that, an address which is on -the same \fInetwork\fP will be tried first. Failing that, they will be tried -in a more-or-less random order unless the \fIsortlist\fP directive was given -in the \fInamed.boot\fP file. \fIsortlist\fP has a syntax similar to -\fIforwarders\fP, \fIxfrnets\fP, and \fIbogusns\fP \(em you give it a list -of dotted-quad networks and it uses these to ``prefer'' some remote name server -addresses over others. If no explicit mask is provided with each element of -a \fIsortlist\fP, one will be inferred based on the high order address bits. -.pp -If you are on a Class C net which has a Class B net between you and the rest -of the Internet, you could try to improve the name server's luck in getting -answers by listing the Class B network's number in a \fIsortlist\fP -directive. This should have the effect of trying ``closer'' servers before -the more ``distant'' ones. Note that this behaviour is new as of \s-1BIND -4.9\s+1. -.pp -The other and older effect of the \fIsortlist\fP directive is to cause -\s-1BIND\s+1 to sort the \fIA\fP records in any response it generates, so as -to put those which appear on the \fIsortlist\fP earlier than those which do -not. This is not as helpful as you might think, since many clients will -reorder the \fIA\fP records either at random or using \s-1LIFO\s+1; also, -consider the fact that the server won't be able to guess the client's network -topology, and so will not be able to accurately order for ``closeness'' to -all possible clients. Doing the ordering in the resolver is clearly superior. -.pp -In actual practice, this directive is used only rarely since it hardwires -information which changes rapidly; a network which is ``close'' today may -be ``distant'' next month. Since \s-1BIND\s+1 builds up a cache of the -remote name servers' response times, it will quickly converge on -``reasonable'' behaviour, which isn't the same as ``optimal'' but it's -close enough. Future directions for \s-1BIND\s+1 include choosing -addresses based on local interface metrics (on hosts that have more than -one) and perhaps on routing table information. We do not intend to solve -the generalized ``multihomed host'' problem, but we should be able to do a -little better than we're doing now. Likewise, we hope to see a higher -level resolver library that sorts responses using topology information that -only exists on the client's host. - -.sh 3 "Bogus Name Servers" -.pp -It happens occasionally that some remote name server goes ``bad''. You can -tell your name server to refuse to listen to or ask questions of certain -other name servers by listing them in a \fIbogusns\fP directive in your -\fInamed.boot\fP file. Its syntax is the same as \fIforwarders\fP, -\fIxfrnets\fP, and \fIsortlist\fP \(em you just give it a list of dotted-quad -Internet addresses. Note that zones delegated to such servers will not be -reachable from clients of your servers; thus you should use this directive -sparingly or not at all. - -.sh 3 "Segmented Boot Files" -.pp -If you are secondary for a lot of zones, you may find it convenient to split -your \fInamed.boot\fP file into a static portion which hardly ever changes -(directives such as \fIdirectory\fP, \fIsortlist\fP, \fIxfrnets\fP and -\fIcache\fP could go here), and dynamic portions that change frequently -(all of your \fIprimary\fP directives might go in one file, and all of your -\fIsecondary\fP directives might go in another file \(em and either or both -of these might be fetched automatically from some neighbor so that they can -change your list of secondary zones without requiring your active -intervention). You can accomplish this via the \fIinclude\fP directive, -which takes just a single file name as its argument. No quotes are needed -around the file name. The file name will be evaluated after the name server -has changed its working directory to that specified in the \fIdirectory\fP -directive, so you can use relative pathnames if your system supports them. - -.sh 2 "Resolver Configuration" -.pp -The configuration file's name is \fI/etc/resolv.conf\fP. -This file designates the name servers on the network that should -be sent queries. -The resolver will try to contact a name server on the localhost if it cannot -find its configuration file. You should install the configuration file -on every host anyway, since this is the only recommended way to specify a -system-level default domain, and you can still list the local host's address -if it runs a name server. -It is considered reasonable to create this file even if you run a local -server, since its contents will be cached by each client of the resolver -library when the client makes its first call to a resolver routine. -.pp -The \fIresolv.conf\fP file contains directives, one per line, of the -following forms: -.(l I -; comment -# another comment -domain \fIlocal-domain\fP -search \fIsearch-list\fP -nameserver \fIserver-address\fP -sortlist \fIsort-list\fP -options \fIoption-list\fP -.)l -Exactly one of the \fIdomain\fP or \fIsearch\fP directives should be given, -exactly once. -If the \fIsearch\fP directive is given, the first item in the given -\fIsearch-list\fP will override any previously-specified \fIlocal-domain\fP. -The \fInameserver\fP directive may be given up to three times; additional -\fInameserver\fP directives will be ignored. Comments may be given by -starting a line with a ``\fB\|;\|\fP'' or ``\fB\|#\|\fP''; note that -comments were not permitted in versions of the resolver earlier than the one -included with \s-1BIND 4.9\s+1 \(em so if your vendor's resolver supports -comments, you know they are really on the ball. -.pp -The \fIlocal-domain\fP will be appended to any query-name that does not -contain a ``\fB\|.\|\fP''. \fIlocal-domain\fP can be overridden on a -per-process basis by setting the \s-1LOCALDOMAIN\s+1 environment variable. -Note that \fIlocal-domain\fP processing can be disabled by setting an -option in the resolver. -.pp -The \fIsearch-list\fP is a list of domains which are tried, in order, -as qualifying domains for query-names which do not contain a ``\fB\|.\|\fP''. -Note that \fIsearch-list\fP processing can be disabled by setting an -option in the resolver. Also note that the environment variable -``\s-1LOCALDOMAIN\s+1'' can override this \fIsearch-list\fP on a per-process -basis. -.pp -The \fIserver-address\fP\|'s are aggregated and then used as the default -destination of queries generated through the resolver. In other words, -this is the way you tell the resolver which name servers it should use. It -is possible for a given client application to override this list, and this -is often done inside the name server (which is itself a \fIresolver\fP -client) and in test programs such as \fInslookup\fP. -Note that if you wish to list the -local host in your resolver configuration file, you should probably use its -primary Internet address rather than a local-host alias such as 127.0.0.1 or -0.0.0.0. This is due to a bug in the handling of connected \s-1SOCK_DGRAM\s+1 -sockets in some versions of the \s+1BSD\s-1 networking code. If you must use -an address-alias, you should prefer 0.0.0.0 (or simply ``0'') over 127.0.0.1, -though be warned that depending on the vintage of your \s-1BSD\s+1-derived -networking code, both of them are capable of failing in their own ways. -If your host's IP -implementation does not create a short-circuit route between the default -interface and the loopback interface, then you might also want to add a -static route (eg. in \fB/etc/rc.local\fP) to do so: -.(b l -\fIroute add myhost.domain.name localhost 1\fP -.)b -.pp -The \fIsort-list\fP is a list of IP address, netmask pairs.

The \s-1BIND\s+1 consists -of a server (or ``daemon'') called \fInamed\fP and a \fIresolver\fP library. -A name server is a network service that enables clients to name resources or -objects and share this information with other objects in the network. This -in effect is a distributed data base system for objects in a computer -network. The \s-1BIND\s+1 server runs in the background, servicing queries -on a well known network port.

It contains all names -from a certain point ``downward'' except those which are delegated to other -zones. A ``delegation point'' has one or more \fINS\fP records in the -``parent zone'', which should be matched by equivalent \fINS\fP records at -the root of the ``delegated zone'' (i.e., the ``@'' name in the zone file). -.pp -Understanding the difference between a ``zone'' and a ``domain'' is crucial -to the proper operation of a name server. As an example, consider the -\s-1DEC.COM\s+1 \fIdomain\fP, which includes names such as -\s-1POBOX1.PA.DEC.COM\s+1 and \s-1QUABBIN.CRL.DEC.COM\s+1 even though -the \s-1DEC.COM\s+1 \fIzone\fP includes only \fIdelegations\fP for the -\s-1PA.DEC.COM\s+1 and \s-1CRL.DEC.COM\s+1 zones. A zone can map exactly -to a single domain, but could also include only part of a domain (the rest -of which could be delegated to other name servers). Technically speaking, -every name in the DNS tree is a ``domain'', even if it is ``terminal'', that -is, has no ``subdomains''. Technically speaking, every subdomain is a domain -and every domain except the root is also a subdomain. The terminology is not -intuitive and you would do well to read RFC's 1033, 1034, and 1035 to gain a -complete understanding of this difficult and subtle topic. -.pp -Though \s-1BIND\s+1 is a \fIDomain\fP Name Server, it deals primarily in terms -of \fIzones\fP. The \fIprimary\fP and \fIsecondary\fP declarations in the -\fInamed.boot\fP file specify \fIzones\fP, not \fIdomains\fP. When you ask -someone if they are willing to be a secondary server for your ``domain'', you -are actually asking for secondary service for some collection of \fIzones\fP. -.pp -Each zone will have one ``primary'' server, which loads the zone contents -from some local file which is edited by humans or perhaps generated -mechanically from some other local file which is edited by humans. Then -there will be some number of ``secondary'' servers, which load the zone -contents using the \s-1IP/DNS\s+1 protocol (that is, the secondary servers will -contact the primary and fetch the zone using \s-1IP/TCP\s+1). This set of -servers (the primary and all of the secondaries) should be listed in the -\fINS\fP records in the parent zone, which will constitute a ``delegation''. -This set of servers must also be listed in the zone file itself, usually -under the ``@'' name which is a magic cookie that means the ``top level'' -or ``root'' of current zone. You can list servers in the zone's -top-level ``@'' \fINS\fP records that are not in the parent's \fINS\fP -delegation, but you cannot list servers in the parent's delegation that are -not present in the zone's ``@''. Any servers listed in the \fINS\fP records -must be configured as authoritative (either primary or secondary) for the -zone. If a server listed in a \fINS\fP record is not authoritative, it -will respond with a ``lame delegation'' when queried. -.sh 1 "Types of Servers" -.pp -Servers do not really have ``types''. A server can be a primary for some -zones and a secondary for others, or it can be only a primary, or only a -secondary, or it can serve no zones and just answer queries via its ``cache''. -Previous versions of this document referred to servers as ``master'' and -``slave'' but we now feel that those distinctions \(em and the assignment of -a ``type'' to a name server \(em are not useful. -.sh 2 "Caching Only Server" -.pp -All servers are caching servers. This means that the server caches the -information that it receives for use until the data expires. A \fICaching -Only Server\fP is a server that is not authoritative for any zone. This -server services queries and asks other servers, who have the authority, for -the information needed. All servers keep data in their cache until the data -expires, based on a \fITTL\fP (``Time To Live'') field which is maintained -for all resource records. -.sh 2 "Remote Server" -.pp -A Remote Server is an option given to people who would like to use -a name server from their workstation or on a machine that has a limited -amount of memory and CPU cycles. -With this option you can run all of the networking programs that use -the name server without the name server running on the local machine. -All of the queries are serviced by a name server that is running on another -machine on the network. -A host which has an -\fI/etc/resolv.conf\fP file listing only remote hosts, and which does not -run a name server of its own, is sometimes called a Remote Server (because -the actual server is remote?) but more -often it is called simply a DNS Client. -This kind of host is technically not a ``server'', -since it has no cache and does not answer queries. -.sh 2 "Slave Server" -.pp -A Slave Server is a server that always forwards queries it cannot -satisfy from its cache, to a fixed list of \fIforwarding\fP servers -instead of interacting -with the name servers for the root and other domains. -The queries to the \fIforwarding servers\fP are recursive queries. -There may be one or more forwarding servers, and they are tried in turn -until the list is exhausted. -A Slave and forwarder configuration is typically used when you do not -wish all the servers at a given site to interact with the rest -of the Internet servers. A typical scenario would involve a number of -workstations and a departmental timesharing machine with Internet -access. The workstations might be -administratively prohibited from having Internet access. -To give the workstations the appearance of access to the Internet -domain system, the workstations could be Slave servers to the timesharing -machine which would forward the queries and interact with other -name servers to resolve the query before returning the answer. -An added benefit of using the forwarding feature is that the central -machine develops a much more complete cache of information that -all the workstations can take advantage of. The use of Slave mode -and forwarding is discussed further under the description of -the \fInamed\fP bootfile commands. -.pp -There is no prohibition against declaring a server to be a \fIslave\fP -even though it has \fIprimary\fP and/or \fIsecondary\fP zones as well; -the effect will still be that anything in the local server's cache or -zones will be answered, and anything else will be forwarded using the -\fIforwarders\fP list. diff --git a/contrib/bind/doc/bog/ucbhosts b/contrib/bind/doc/bog/ucbhosts deleted file mode 100644 index 2cb26355eb85..000000000000 --- a/contrib/bind/doc/bog/ucbhosts +++ /dev/null @@ -1,118 +0,0 @@ -.\" ++Copyright++ 1986, 1988 -.\" - -.\" Copyright (c) 1986, 1988 -.\" The Regents of the University of California.

More information on those names can be found in the -description of the <A HREF="acl.html"><CODE>acl</CODE></A> statement. - -<P>The addition of the <CODE>key</CODE> -clause made the name of this syntactic element something of a -misnomer, since security keys can be used to validate access without -regard to a host or network address. Nonetheless, the term "address -match list" is still used throughout the documentation.</P> - -<P>When a given IP address or prefix is compared to an address match -list, the list is traversed in order until an element matches. The -interpretation of a match depends on whether the list is being used -for access control, defining <CODE>listen-on</CODE> ports, or as a -topology, and whether the element was negated.</P> - -<P>When used as an access control list, a non-negated match allows -access and a negated match denies access. If there is no match, -access is denied. The clauses <CODE>allow-query</CODE>, -<CODE>allow-transfer</CODE>, <CODE>allow-update</CODE> and -<CODE>blackhole</CODE> all use address match lists like this. -Similarly, the <CODE>listen-on</CODE> -option will cause the server to not accept queries on any of the -machine's addresses which do not match the list. - -<P>When used with the <CODE>topology</CODE> clause, a non-negated -match returns a distance based on its position on the list (the closer -the match is to the start of the list, the shorter the distance is -between it and the server). A negated match will be assigned the -maximum distance from the server. If there is no match, the address -will get a distance which is further than any non-negated list -element, and closer than any negated element.</P> - -<P>Because of the first-match aspect of the algorithm, an element that -defines a subset of another element in the list should come before the -broader element, regardless of whether either is negated. For -example, in <CODE>1.2.3/24; ! 1.2.3.13;</CODE> the 1.2.3.13 -element is completely useless, because the algorithm will match -any lookup for 1.2.3.13 to the 1.2.3/24 element.

If the server's global debug level is greater than -zero, debugging mode will be active. The global debug level is -set either by starting the <CODE>named</CODE> server with the "-d" -flag followed by a positive integer, or by sending the running server the -SIGUSR1 signal (for example, by using "ndc trace"). The global debug -level can be set to zero, and debugging mode turned off, by sending -the server the SIGUSR2 signal ("ndc notrace").

If not -specified, the default is "named.memstats". - -<DT><CODE>pid-file</CODE> -<DD> -The pathname of the file the server writes its process ID in. If not -specified, the default is operating system dependent, but is usually -"/var/run/named.pid" or "/etc/named.pid". The pid-file is used by -programs like "ndc" that want to send signals to the running -nameserver. - -<DT><CODE>statistics-file</CODE> -<DD> -The pathname of the file the server appends statistics to when it -receives <CODE>SIGILL</CODE> signal (<CODE>ndc stats</CODE>).

Do not turn off -<CODE>auth-nxdomain</CODE> unless you are sure you know what you are -doing, as some older software won't like it. - -<DT><CODE>deallocate-on-exit</CODE> -<DD> -If <CODE>yes</CODE>, the server will painstakingly deallocate every object it -it allocated, when it exits, and then write a memory usage report to -the <CODE>memstatistics-file</CODE>. The default is <CODE>no</CODE>, because -it is faster to let the operating system clean up. -<CODE>deallocate-on-exit</CODE> is handy for detecting memory leaks. - -<DT><CODE>dialup</CODE> -<DD> -If <CODE>yes</CODE>, the server treats all zones as if they are -doing zone transfers across a dial on demand dialup link, which can -be brought up by traffic originating from this server. This has -different effects according to zone type and concentrates the zone -maintenance so that it all happens in a short interval, once every -<CODE>heartbeat-interval</CODE> and hopefully during the one call. -It also suppresses some of the normal zone maintainance traffic. -The default is <CODE>no</CODE>.

The default is <CODE>no</CODE>. <I>Note:</I> -turning on <CODE>host-statistics</CODE> can consume huge amounts of memory. - -<DT><CODE>maintain-ixfr-base</CODE> -<DD> -If <CODE>yes</CODE>, a transaction log is kept for -Incremental Zone Transfer. The default is <CODE>no</CODE>. - -<DT><CODE>multiple-cnames</CODE> -<DD> -If <CODE>yes</CODE>, multiple CNAME resource records will be -allowed for a domain name. The default is <CODE>no</CODE>. Allowing -multiple CNAME records is against standards and is not recommended. -Multiple CNAME support is available because previous versions of BIND -allowed multiple CNAME records, and these records have been used for load -balancing by a number of sites. - -<DT><CODE>notify</CODE> -<DD> -If <CODE>yes</CODE> (the default), DNS NOTIFY messages are sent when a -zone the server is authoritative for changes. The use of NOTIFY -speeds convergence between the master and its slaves. Slave servers -that receive a NOTIFY message, and understand it, will contact the -master server for the zone to see if they need to do a zone transfer. If -they do, they will initiate it immediately. The <CODE>notify</CODE> -option may also be specified in the <CODE>zone</CODE> statement, in which -case it overrides the <CODE>options notify</CODE> statement. - -<DT><CODE>recursion</CODE> -<DD> -If <CODE>yes</CODE>, and a DNS query requests recursion, the -server will attempt to do all the work required to answer the query. -If recursion is not on, the server will return a referral to the -client if it doesn't know the answer. The default is <CODE>yes</CODE>. -See also <CODE>fetch-glue</CODE> above. - -<DT><CODE>rfc2308-type1</CODE> -<DD> -If <CODE>yes</CODE>, the server will send NS records along with the SOA -record for negative answers. -You need to set this to <CODE>no</CODE> if you have an old BIND -server using you as a forwarder that does not understand negative answers -which contain both SOA and NS records or you have an old version of sendmail. -The correct fix is to upgrade the broken server or sendmail. -The default is <CODE>no</CODE>. - -<DT><CODE>use-id-pool</CODE> -<DD> -If <CODE>yes</CODE>, the server will keep track of its own outstanding -query ID's to avoid duplication and increase randomness. This will result -in 128KB more memory being consumed by the server. -The default is <CODE>no</CODE>. - -<DT><CODE>treat-cr-as-space</CODE> -<DD> -If <CODE>yes</CODE>, the server will treat '\r' characters the same way it -treats a ' ' or '\t'. This may be necessary when loading zone files on a -UNIX system that were generated on an NT or DOS machine. The default is <CODE>no</CODE>. - -</DL> - -<A NAME="Also-notify"><H4>Also-Notify</H4></A> - -<DT><CODE>also-notify</CODE> -<P> -Defines a global list of IP addresses that also get sent NOTIFY messages -whenever a fresh copy of the zone is loaded. This helps to ensure that -copies of the zones will quickly converge on ``stealth'' servers. -If an <CODE>also-notify</CODE> list is given in a <CODE>zone</CODE> -statement, it will override the <CODE>options also-notify</CODE> statement. -When a <CODE>zone notify</CODE> statement is set to <CODE>no</CODE>, -the IP addresses in the global <CODE>also-notify</CODE> list will not get -sent NOTIFY messages for that zone. -The default is the empty list (no global notification list). - -<A NAME="Forwarding"><H4>Forwarding</H4></A> - -<P>The forwarding facility can be used to create a large site-wide -cache on a few servers, reducing traffic over links to external -nameservers. It can also be used to allow queries by servers that do -not have direct access to the Internet, but wish to look up exterior -names anyway. Forwarding occurs only on those queries for which the -server is not authoritative and does not have the answer in its cache. - -<DL> -<DT><CODE>forward</CODE> -<DD> -This option is only meaningful if the <CODE>forwarders</CODE> list is -not empty. A value of <CODE>first</CODE>, the default, causes the -server to query the forwarders first, and if that doesn't answer the -question the server will then look for the answer itself. If -<CODE>only</CODE> is specified, the server will only query the -forwarders. - -<DT><CODE>forwarders</CODE> -<DD> -Specifies the IP addresses to be used for forwarding. The default is the -empty list (no forwarding). -</DL> - -<P>Forwarding can also be configured on a per-zone basis, allowing for -the global forwarding options to be overridden in a variety of ways. -You can set particular zones to use different forwarders, or have -different <CODE>forward only/first</CODE> behavior, or to not forward -at all. See the <A HREF="zone.html"><CODE>zone</CODE></A> statement -for more information. - -<P>Future versions of BIND 8 will provide a more powerful forwarding -system. The syntax described above will continue to be supported. - -<a name="NameChecking"><H4>Name Checking</H4></a> - -<P>The server can check domain names based upon their expected client contexts. -For example, a domain name used as a hostname can be checked for compliance -with the RFCs defining valid hostnames. - -<P>Three checking methods are available: - -<DL> -<DT><CODE>ignore</CODE> -<DD> -No checking is done. - -<DT><CODE>warn</CODE> -<DD> -Names are checked against their expected client contexts.

See -<VAR><A HREF="address_list.html">address_match_list</A></VAR> for details -on how to specify IP address lists. - -<DL> -<DT><CODE>allow-query</CODE> -<DD> -Specifies which hosts are allowed to ask ordinary questions. -<CODE>allow-query</CODE> may also be specified in the -<CODE>zone</CODE> statement, in which case it overrides the -<CODE>options allow-query</CODE> statement. If not specified, the default is -to allow queries from all hosts. - -<DT><CODE>allow-transfer</CODE> -<DD> -Specifies which hosts are allowed to receive zone transfers from the -server. <CODE>allow-transfer</CODE> may also be specified in the -<CODE>zone</CODE> statement, in which case it overrides the -<CODE>options allow-transfer</CODE> statement. If not specified, the default -is to allow transfers from all hosts. - -<DT><CODE>allow-recursion</CODE> -<DD> -Specifies which hosts are allowed to make recursive queries through this -server. If not specified, the default is to allow recursive queries from -all hosts. - -<DT><CODE>blackhole</CODE> -<DD> -Specifies a list of addresses that the server will not accept queries from -or use to resolve a query. Queries from these addresses will not be -responded to. -</DL> - -<H4>Interfaces</H4> - -<P>The interfaces and ports that the server will answer queries from may -be specified using the <CODE>listen-on</CODE> option. <CODE>listen-on</CODE> -takes an optional port, and an -<VAR><A HREF="address_list.html">address_match_list</A></VAR>. The server will -listen on all interfaces allowed by the address match list. If a port is -not specified, port 53 will be used. - -<P>Multiple <CODE>listen-on</CODE> statements are allowed. For example, - -<PRE> - listen-on { 5.6.7.8; }; - listen-on port 1234 { !1.2.3.4; 1.2/16; }; -</PRE> - -will enable the nameserver on port 53 for the IP address 5.6.7.8, and -on port 1234 of an address on the machine in net 1.2 that is not -1.2.3.4. - -<P>If no <CODE>listen-on</CODE> is specified, the server will listen on port -53 on all interfaces. - -<H4>Query Address</H4> - -<P>If the server doesn't know the answer to a question, it will query -other nameservers. <CODE>query-source</CODE> specifies the address -and port used for such queries. If <CODE>address</CODE> is -<CODE>*</CODE> or is omitted, a wildcard IP address -(<CODE>INADDR_ANY</CODE>) will be used. If <CODE>port</CODE> is -<CODE>*</CODE> or is omitted, a random unprivileged port will be used. -The default is - -<PRE> - query-source address * port *; -</PRE> - -<P>Note: <CODE>query-source</CODE> currently applies only to UDP queries; -TCP queries always use a wildcard IP address and a random unprivileged -port. - -<A name="ZoneTransfers"><H4>Zone Transfers</H4></A> - -<DL> -<DT><CODE>max-transfer-time-in</CODE> -<DD> -Inbound zone transfers (<CODE>named-xfer</CODE> processes) running -longer than this many minutes will be terminated.

The default is <CODE>one-answer</CODE>. -<CODE>transfer-format</CODE> may be -overridden on a per-server basis by using the <CODE>server</CODE> statement. - -<DT><CODE>transfers-in</CODE> -<DD> -The maximum number of inbound zone transfers that can be running -concurrently. The default value is 10. Increasing -<CODE>transfers-in</CODE> may speed up the convergence of slave zones, -but it also may increase the load on the local system. - -<DT><CODE>transfers-out</CODE> -<DD> -This option will be used in the future to limit the number of -concurrent outbound zone transfers. It is checked for syntax, but is -otherwise ignored. - -<DT><CODE>transfers-per-ns</CODE> -<DD> -The maximum number of inbound zone transfers (<CODE>named-xfer</CODE> -processes) that can be concurrently transferring from a given remote -nameserver. The default value is 2. Increasing -<CODE>transfers-per-ns</CODE> may speed up the convergence of slave -zones, but it also may increase the load on the remote nameserver. -<CODE>transfers-per-ns</CODE> may be overridden on a per-server basis -by using the <CODE>transfers</CODE> phrase of the <CODE>server</CODE> -statement. - -<DT><CODE>transfer-source</CODE> -<DD> -<CODE>transfer-source</CODE> determines which local address will be bound -to the TCP connection used to fetch all zones transferred inbound by the -server. If not set, it defaults to a system controlled value which will -usually be the address of the interface ``closest to'' the remote end. -This address must appear in the remote end's <CODE>allow-transfer</CODE> -option for the zone being transferred, if one is specified. This statement -sets the <CODE>transfer-source</CODE> for all zones, but can be overridden -on a per-zone basis by including a <CODE>transfer-source</CODE> statement -within the zone block in the configuration file. - -<DT><CODE>serial-queries</CODE> -<DD> -Slave servers will periodically query master servers to find out if zone -serial numbers have changed. Each such query uses a minute amount of the -slave server's network bandwidth, but more importantly each query uses a -small amount of <I>memory</I> in the slave server while waiting for the -master server to respond. The <CODE>serial-queries</CODE> option sets the -maximum number of concurrent serial-number queries allowed to be outstanding -at any given time. The default is four (4). -<B>Note:</B> -If a server loads a large (tens or hundreds of thousands) number of slave -zones, this limit should be raised to the high hundreds or low -thousands -- otherwise the slave server may never actually become aware of -zone changes in the master servers. Beware, though, that setting this limit -arbitrarily high can spend a considerable amount of your slave server's -network, CPU, and memory resources.

All query options are -accessible from the command line. -.Pp -The usual simple use of -.Ic dig -will take the form: -.Pp -.Bd -ragged -offset indent-two -.Ic dig @ Ns Ar server domain query-type query-class -.Ed -.Pp -where: -.Bl -tag -width Fl -.It Ar server -may be either a domain name or a dot-notation -Internet address. If this optional field is omitted, -.Ic dig -will attempt to use the default name server for your machine. -.sp 1 -.Em Note: -If a domain name is specified, this will be resolved -using the domain name system resolver (i.e., BIND). If your -system does not support DNS, you may -.Em have -to specify a -dot-notation address. Alternatively, if there is a server -at your disposal somewhere, all that is required is that -.Pa /etc/resolv.conf -be present and indicate where the default -name servers reside, so that -.Ar server -itself can be resolved. See -.Xr resolver @FORMAT_EXT@ -for information on -.Pa /etc/resolv.conf . -.Sy WARNING: -Changing -.Pa /etc/resolv.conf -will affect both the standard resolver library and -.Pq potentially -several programs which use it. -As an option, the user may set the -environment variable -.Ev LOCALRES -to name a file which is to -be used instead of -.Pa /etc/resolv.conf -.Po Ns Ev LOCALRES -is specific to the -.Ic dig -resolver and is not referenced by the standard resolver -.Pc . -If the -.Ev LOCALRES -variable is not set or the specified file -is not readable, then -.Pa /etc/resolv.conf -will be used. -.It Ar domain -is the domain name for which you are requesting information. -See the -.Fl x -option (documented in the -.Sx OTHER OPTIONS -subsection of this section) for convenient way to specify inverse address -query. -.It Ar query-type -is the type of information (DNS query type) that -you are requesting. If omitted, the default is -.Dq Ar a -.Pq Dv T_A = Ar address . -The following types are recognized: -.Pp -.Bl -hang -width "hinfo T_HINFO " -compact -.It Ar a\ \ \ \ \ \ Dv T_A -network address -.It Ar any\ \ \ \ Dv T_ANY -all/any information about specified domain -.It Ar mx\ \ \ \ \ Dv T_MX -mail exchanger for the domain -.It Ar ns\ \ \ \ \ Dv T_NS -name servers -.It Ar soa\ \ \ \ Dv T_SOA -zone of authority record -.It Ar hinfo\ \ Dv T_HINFO -host information -.It Ar axfr\ \ \ Dv T_AXFR -zone transfer (must ask an authoritative server) -.It Ar txt\ \ \ \ Dv T_TXT -arbitrary number of strings -.El -.Pp -(See RFC 1035 for the complete list.) -.It Ar query-class -is the network class requested in the query.

This may be useful if running -.Ic dig -in batch -mode. Instead of resolving every -.Ar @server-domain-name -in a list of queries, you can avoid the overhead of doing -so, and still have the domain name on the command line -as a reference. Example: -.Pp -.Bd -ragged -offset indent-two -.Ic dig @128.9.0.32 %venera.isi.edu mx isi.edu -.Ed -.Pp -.It Fl Aq Ar dig option -.Dq Fl -is used to specify an option which affects the operation of -.Ic dig . -The following options are currently -available (although not guaranteed to be useful): -.Bl -tag -width Fl -.It Fl x Ar dot-notation-address -Convenient form to specify inverse address mapping. -Instead of -.Dq Ic dig 32.0.9.128.in-addr.arpa , -one can simply -.Dq Ic dig -x 128.9.0.32 . -.It Fl f Ar file -File for -.Ic dig -batch mode. The file contains a list -of query specifications -( -.Ns Ic dig -command lines) which are to be executed successively. Lines beginning with -.Sq \&; , -.Sq # , -or -.Sq \en -are ignored. Other options -may still appear on command line, and will be in -effect for each batch query. -.It Fl T Ar time -Time in seconds between start of successive -queries when running in batch mode. Can be used -to keep two or more batch -.Ic dig -commands running -roughly in sync. Default is zero. -.It Fl p Ar port -Port number. Query a name server listening to a -non-standard port number. Default is 53. -.It Fl P Ns Bq Ar ping-string -After query returns, execute a -.Xr ping @SYS_OPS_EXT@ -command for response time comparison. This rather -unelegantly makes a call to the shell.

To perform lookups, you must first initialize a -.IR context , -an opaque object which stores information used internally by the -library between calls. -.I hesiod_init -initializes a context, storing a pointer to the context in the -location pointed to by the -.I context -argument. -.I hesiod_end -frees the resources used by a context. -.PP -.I hesiod_resolve -is the primary interface to the library. If successful, it returns a -list of one or more strings giving the records matching -.I name -and -.IR type . -The last element of the list is followed by a NULL pointer. It is the -caller's responsibility to call -.I hesiod_free_list -to free the resources used by the returned list. -.PP -.I hesiod_to_bind -converts -.I name -and -.I type -into the DNS name used by -.IR hesiod_resolve . -It is the caller's responsibility to free the returned string using -.IR free . -.SH RETURN VALUES -If successful, -.I hesiod_init -returns 0; otherwise it returns \-1 and sets -.I errno -to indicate the error. On failure, -.I hesiod_resolve -and -.I hesiod_to_bind -return NULL and set the global variable -.I errno -to indicate the error. -.SH ENVIRONMENT -If the environment variable -.B HES_DOMAIN -is set, it will override the domain in the Hesiod configuration file. -If the environment variable -.B HESIOD_CONFIG -is set, it specifies the location of the Hesiod configuration file. -.SH SEE ALSO -`Hesiod - Project Athena Technical Plan -- Name Service', named(8), -hesiod.conf(5) -.SH ERRORS -Hesiod calls may fail because of: -.IP ENOMEM -Insufficient memory was available to carry out the requested -operation. -.IP ENOEXEC -.I hesiod_init -failed because the Hesiod configuration file was invalid. -.IP ECONNREFUSED -.I hesiod_resolve -failed because no name server could be contacted to answer the query. -.IP EMSGSIZE -.I hesiod_resolve -failed because the query or response was too big to fit into the -packet buffers. -.IP ENOENT -.I hesiod_resolve -failed because the name server had no text records matching -.I name -and -.IR type , -or -.I hesiod_to_bind -failed because the -.I name -argument had a domain extension which could not be resolved with type -``rhs-extension'' in the local Hesiod domain. -.SH AUTHOR -Steve Dyer, IBM/Project Athena -.br -Greg Hudson, MIT Team Athena -.br -Copyright 1987, 1988, 1995, 1996 by the Massachusetts Institute of Technology. -.SH BUGS -The strings corresponding to the -.I errno -values set by the Hesiod functions are not particularly indicative of -what went wrong, especially for -.I ENOEXEC -and -.IR ENOENT . diff --git a/contrib/bind/doc/man/host.1 b/contrib/bind/doc/man/host.1 deleted file mode 100644 index 017d0829845d..000000000000 --- a/contrib/bind/doc/man/host.1 +++ /dev/null @@ -1,316 +0,0 @@ -.\" ++Copyright++ 1993 -.\" - -.\" Copyright (c) 1993 -.\" The Regents of the University of California.

It gets this information -from a set of interconnected servers that are spread across the -country. By default, it simply converts between host names and -Internet addresses. However, with the -.Dq Fl t -or -.Dq Fl a -options, it can be used -to find all of the information about this host that is maintained -by the domain server. -.Pp -The arguments can be either host names or host numbers. The program -first attempts to interpret them as host numbers. If this fails, -it will treat them as host names. A host number consists of -first decimal numbers separated by dots, e.g. 128.6.4.194 -A host name consists of names separated by dots, e.g. topaz.rutgers.edu. -Unless the name ends in a dot, the local domain -is automatically tacked on the end. Thus, a Rutgers user can say -.Pp -.D1 Ic host topaz -.Pp -and it will actually look up "topaz.rutgers.edu". -If this fails, the name is tried unchanged (in this case, "topaz"). -This same convention is used for mail and other network utilities. -The actual suffix to tack on the end is obtained -by looking at the results of a -.Xr hostname @CMD_EXT@ -call, and using everything -starting at the first dot. (See below for a description of -.Sx CUSTOMIZING HOST NAME LOOKUP . ) -.Pp -The first argument is the host name you want to look up. -If this is a number, an -.Dq inverse query -is done, i.e. the domain -system looks in a separate set of databases used to convert numbers -to names. -.Pp -The second argument is optional. It -allows you to specify a particular server to query. If you don't -specify this argument, the default server (normally the local machine) -is used. -.Pp -If a name is specified, you may see output of three different kinds. -Here is an example that shows all of them: -.Pp -.D1 Ic % host sun4 -.Dl sun4.rutgers.edu is a nickname for ATHOS.RUTGERS.EDU -.Dl ATHOS.RUTGERS.EDU has address 128.6.5.46 -.Dl ATHOS.RUTGERS.EDU has address 128.6.4.4 -.Dl ATHOS.RUTGERS.EDU mail is handled by ARAMIS.RUTGERS.EDU -.Pp -The user has typed the command -.Dq Ic host sun4 . -The first line indicates that the name -.Dq Li sun4.rutgers.edu -is actually a nickname. The official host name is -.Dq Li ATHOS.RUTGERS.EDU . -The next two lines show the -address. If a system has more than one network interface, there -will be a separate address for each. The last line indicates -that -.Li ATHOS.RUTGERS.EDU -does not receive its own mail. Mail for -it is taken by -.Li ARAMIS.RUTGERS.EDU . -There may be more than one -such line, since some systems have more than one other system -that will handle mail for them. Technically, every system that -can receive mail is supposed to have an entry of this kind. If -the system receives its own mail, there should be an entry -the mentions the system itself; for example, -.Pp -.D1 Li XXX mail is handled by XXX -.Pp -However, many systems that receive -their own mail do not bother to mention that fact. If a system -has a -.Dq Li mail is handled by -entry, but no address, this indicates -that it is not really part of the Internet, but a system that is -on the network will forward mail to it. Systems on Usenet, Bitnet, -and a number of other networks have entries of this kind. -.Sh OPTIONS -There are a number of options that can be used before the -host name. Most of these options are meaningful only to the -staff who have to maintain the domain database. -.Bl -tag -width Fl -.It Fl w -This causes -.Ic host -to wait forever for a response. Normally -it will time out after approximate one minute. -.It Fl v -Use "verbose" format for printout. This -is the official domain master file format, which is documented -in the man page for -.Xr @INDOT@named @SYS_OPS_EXT@ . -Without this option, output still follows -this format in general terms, but some attempt is made to make it -more intelligible to normal users. Without -.Dq Fl v , -any "a", "mx", and "cname" records -are written out as "has address", "mail is handled by", and -"is a nickname for" (respectively), and TTL and class fields are not shown. -.It Fl r -Turn off recursion in the request. -This means that the name server will return only data it has in -its own database. It will not ask other servers for more -information. -.It Fl d -Turn on debugging. Network transactions are shown in detail. -.It Fl t Ar querytype -Allows you to specify a particular -.Ar querytype -of information -to be looked up. The arguments are defined in the man page for -.Xr @INDOT@named @SYS_OPS_EXT@ . -Currently-supported types include: -.Dq Cm a , -.Dq Cm ns , -.Dq Cm md , -.Dq Cm mf , -.Dq Cm cname , -.Dq Cm soa , -.Dq Cm mb , -.Dq Cm mg , -.Dq Cm mr , -.Dq Cm null , -.Dq Cm wks , -.Dq Cm ptr , -.Dq Cm hinfo , -.Dq Cm minfo , -.Dq Cm mx , -.Dq Cm uinfo , -.Dq Cm uid , -.Dq Cm gid , -.Dq Cm unspec . -Additionally, the wildcard, which may be written -as either -.Dq Cm any -or -.Dq Cm * , -can be used to specify any (all) of the above types. -Types must be given in lower case. -Note that the default is to look first for -.Dq Cm a , -and then -.Dq Cm mx , -except that if the verbose option is turned on, the default is only -.Dq Cm a . -The -.Dq Fl t -option is particularly useful for filtering information returned by -.Ic host ; -see the explanation of the -.Dq Fl l -option, below, for more information. -.It Fl a -.Dq all ; -this is equivalent to -.Dq Fl v Fl t Cm any . -.It Fl l -List a complete domain; e.g.: -.Pp -.D1 Ic host -l rutgers.edu -.Pp -will give a listing of all hosts in the rutgers.edu domain. The -.Dq Fl t -option is used to filter what information is presented, as you -would expect. The default is address information, which also -include PTR and NS records. The command -.Pp -.D1 Ic host -l -v -t any rutgers.edu -.Pp -will give a complete download of the zone data for rutgers.edu, -in the official master file format. (However the SOA record is -listed twice, for arcane reasons.) -.Pp -.Sy NOTE: -.Dq Fl l -is implemented by -doing a complete zone transfer and then filtering out the information -the you have asked for. This command should be used only if it -is absolutely necessary. -.Sh CUSTOMIZING HOST NAME LOOKUP -In general, if the name supplied by the user does not -have any dots in it, a default domain is appended to the end. -This domain can be defined in -.Pa /etc/resolv.conf , -but is normally derived -by taking the local hostname after its first dot. The user can override -this, and specify a different default domain, using the environment -variable -.Ev LOCALDOMAIN . -In addition, the user can supply his own abbreviations for host names. -They should be in a file consisting of one line per abbreviation. -Each line contains an abbreviation, a space, and then the full -host name. The name file must be contained in the -.Ev HOSTALIASES -environment variable. -.Sh ENVIRONMENT -.Bl -tag -width "/etc/resolv.conf " -compress -.It Ev HOSTALIASES -Name of file containing -.Pq Ar host alias , full hostname -pairs. -.El -.Sh FILES -.Bl -tag -width "/etc/resolv.conf " -compress -.It Pa /etc/resolv.conf -See -.Xr resolver @FORMAT_EXT@ . -.It Ev HOSTALIASES -Name of file containing -.Pq Ar host alias , full hostname -pairs. -.El -.Sh SEE ALSO -.Xr @INDOT@named @SYS_OPS_EXT@ , -.Xr resolver @FORMAT_EXT@ . -.Sh BUGS -Unexpected effects can happen when you type a name that is not -part of the local domain. Please always keep in mind the -fact that the local domain name is tacked onto the end of every -name, unless it ends in a dot. Only if this fails is the name -used unchanged. -.Pp -The -.Dq Fl l -option only tries the first name server listed for the -domain that you have requested. If this server is dead, you -may need to specify a server manually. E.g., to get a listing -of foo.edu, you could try -.Pp -.D1 Ic host -t ns foo.edu -.Pp -to get a list of all the name servers for foo.edu, and then try -.Pp -.D1 Ic host -l foo.edu xxx -.Pp -for all -.Dq Ic xxx -on the list of name servers, until you find one that works. diff --git a/contrib/bind/doc/man/hostname.7 b/contrib/bind/doc/man/hostname.7 deleted file mode 100644 index 6a92d642d4e2..000000000000 --- a/contrib/bind/doc/man/hostname.7 +++ /dev/null @@ -1,171 +0,0 @@ -.\" Copyright (c) 1987 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" Redistribution and use in source and binary forms are permitted -.\" provided that the above copyright notice and this paragraph are -.\" duplicated in all such forms and that any documentation, -.\" advertising materials, and other materials related to such -.\" distribution and use acknowledge that the software was developed -.\" by the University of California, Berkeley.

A domain is a hierarchical, dot-separated list -of subdomains. For example, the machine -.Dq Li monet , -in the -.Dq Li Berkeley -subdomain of the -.Dq Li EDU -subdomain of the Internet Domain Name System would be represented as -.Pp -.Dl monet.Berkeley.EDU -.Pp -(with no trailing dot). -.Pp -Hostnames are often used with network client and server programs, -which must generally translate the name to an address for use. -(This task is usually performed by the library routine -.Xr gethostbyname @LIB_NETWORK_EXT@ . ) -The default method for resolving hostnames by the Internet name resolver is -to follow RFC 1535's security recommendations. Actions can be taken -by the administrator to override these recommendations and to have the -resolver behave the same as earlier, non-RFC 1535 -resolvers. -.Pp -The default method (using RFC 1535 guidelines) follows: -.Pp -If the name consists of a single component, i.e. contains no dot, and if the -environment variable -.Dq Ev HOSTALIASES -is set to the name of a file, -that file is searched for a string matching the input hostname. The file -should consist of lines made up of two strings separated by white-space, the -first of which is the hostname alias, and the second of which is the complete -hostname to be substituted for that alias. If a case-insensitive match is -found between the hostname to be resolved and the first field of a line in -the file, the substituted name is looked up with no further processing. -.Pp -If there is at least one dot in the name, then the name is first tried -.Dq as-is . -The number of dots to cause this action is configurable by setting the -threshold using the -.Dq Li ndots -option in -.Pa /etc/resolv.conf -(default: 1). If the name ends with a dot, the trailing dot is -removed, and the remaining name is looked up (regardless of the setting of -the -.Li ndots -option), without further processing. -.Pp -If the input name does not end with a trailing dot, it is looked up by -searching through a list of domains until a match is found. If neither the -search option in the -.Pa /etc/resolv.conf -file or the -.Dq Ev LOCALDOMAIN -environment variable is used, then the -search list of domains contains only the full domain specified by the -.Li domain -option (in -.Pa /etc/resolv.conf ) -or the domain used in the local hostname (see -.Xr hostname @CMD_EXT@ -and -.Xr resolver @FORMAT_EXT@ ) . -For example, if the -.Dq Li domain -option is set to -.Li CS.Berkeley.EDU , -then only -.Li CS.Berkeley.EDU -will be in the search list, and this will be the only -domain appended to the partial hostname. For example, if -.Dq Li lithium -is the name to be resolved, this would make -.Li lithium.CS.Berkeley.EDU -the only name to be tried using the search list. -.Pp -If the -.Li search -option is used in -.Pa /etc/resolv.conf -or the environment variable -.Dq Ev LOCALDOMAIN -is set by the user, then -the search list will include what is set by these methods. For -example, if the -.Dq Li search -option contained -.Pp -.Dl CS.Berkeley.EDU CChem.Berkeley.EDU Berkeley.EDU -.Pp -then the partial hostname (e.g., -.Dq Li lithium ) -will be tried with -.Em each -domain name appended (in the same order specified); the resulting hostnames -that would be tried are: -.Bd -literal -offset indent -lithium.CS.Berkeley.EDU -lithium.CChem.Berkeley.EDU -lithium.Berkeley.EDU -.Ed -.Pp -The environment variable -.Dq Ev LOCALDOMAIN -overrides the -.Dq Li search -and -.Dq Li domain -options, and if both -.Li search -and -.Li domain -options are present in the resolver configuration file, then only the -.Em last -one listed is used (see -.Xr resolver @FORMAT_EXT@ ) . -.Pp -If the name was not previously tried -.Dq as-is -(i.e., it fell below the -.Dq Li ndots -threshold or did not contain a dot), then the name as -originally provided is attempted. -.Sh ENVIRONMENT -.Bl -tag -width "/etc/resolv.conf " -compress -.It Ev LOCALDOMAIN -Affects domains appended to partial hostnames. -.It Ev HOSTALIASES -Name of file containing -.Pq Ar host alias , full hostname -pairs. -.El -.Sh FILES -.Bl -tag -width "/etc/resolv.conf " -compress -.It Pa /etc/resolv.conf -See -.Xr resolve @FORMAT_EXT@ . -.It Ev HOSTALIASES -Name of file containing -.Pq Ar host alias , full hostname -pairs. -.Sh SEE ALSO -.Xr gethostbyname @LIB_NETWORK_EXT@ , -.Xr resolver @FORMAT_EXT@ , -.Xr mailaddr @DESC_EXT@ , -.Xr @INDOT@named @SYS_OPS_EXT@ . diff --git a/contrib/bind/doc/man/inet_cidr.3 b/contrib/bind/doc/man/inet_cidr.3 deleted file mode 100644 index 9aeb1026f1da..000000000000 --- a/contrib/bind/doc/man/inet_cidr.3 +++ /dev/null @@ -1,94 +0,0 @@ -.\" $Id: inet_cidr.3,v 8.2 1999/01/08 18:54:24 vixie Exp $ -.\" -.\"Copyright (c) 1998,1999 by Internet Software Consortium -.\" -.\"Permission to use, copy, modify, and distribute this software for any -.\"purpose with or without fee is hereby granted, provided that the above -.\"copyright notice and this permission notice appear in all copies. -.\" -.\"THE SOFTWARE IS PROVIDED "AS IS" AND INTERNET SOFTWARE CONSORTIUM DISCLAIMS -.\"ALL WARRANTIES WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES -.\"OF MERCHANTABILITY AND FITNESS.

This behavior is, therefore, not the default. -.Pp -The merge option only affects lookups in the groups map. -If set, subsequent access methods will be tried in order to cause -local users to appear in NIS (or other remote) groups in addition -to the local groups. -.Sh EXAMPLE -.Bd -literal -offset indent -# Get password entries from local file, or failing that, NIS -passwd local continue -passwd nis - -# Build group membership from both local file, and NIS. -group local continue,merge -group nis - -# Services comes from just the local file. -services local - -protocols local - -# Hosts comes first from DNS, failing that, the local file -hosts dns continue -hosts local - -# Networks comes first from the local file, and failing -# that the, irp daemon -networks local continue -networks irp - -netgroup local -.Ed -.Sh NOTES -If a local user needs to be in the local host's -.Dq wheel -group but not in every host's -.Dq wheel -group, put them in the local host's -.Pa /etc/group -.Dq wheel -entry and set up the -.Dq groups -portion of your -.Pa /etc/irs.conf -file as: -.Bd -literal -offset indent -group local continue,merge -group nis -.Ed -.Pp -NIS takes a long time to time out. -Especially for hosts if you use the -.Fl d -option to your server's -.Dq ypserv -daemon. -.Pp -It is important that the -.Pa irs.conf -file contain an entry for each map. -If a map is not mentioned in the -.Pa irs.conf -file, all queries to that map will fail. -.Pp -The classic NIS mechanism for specifying union namespaces is to add an entry -to a local map file whose name is ``+''. In IRS, this is done via ``continue'' -and/or ``merge'' map options. While this results in a small incompatibility -when local map files are imported from non-IRS systems to IRS systems, there -are compensating advantages in security and configurability. -.Sh FILES -.Bl -tag -width /etc/irs.confXXXX -compact -.It Pa /etc/irs.conf -The file -.Nm irs.conf -resides in -.Pa /etc . -.El -.Sh SEE ALSO -.Xr groups 5 , -.Xr hosts 5 , -.Xr netgroup 5 , -.Xr networks 5 , -.Xr passwd 5 , -.Xr protocols 5 , -.Xr services 5 diff --git a/contrib/bind/doc/man/mailaddr.7 b/contrib/bind/doc/man/mailaddr.7 deleted file mode 100644 index 270fe9c9d9b1..000000000000 --- a/contrib/bind/doc/man/mailaddr.7 +++ /dev/null @@ -1,179 +0,0 @@ -.\" Copyright (c) 1983, 1987 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" Redistribution and use in source and binary forms are permitted -.\" provided that the above copyright notice and this paragraph are -.\" duplicated in all such forms and that any documentation, -.\" advertising materials, and other materials related to such -.\" distribution and use acknowledge that the software was developed -.\" by the University of California, Berkeley.

These addresses are in the general format -.Pp -.Bd -ragged -offset indent-two -.Li user@domain -.Ed -.Pp -where a domain is a hierarchical, dot-separated list of subdomains. For -example, the address -.Pp -.Bd -ragged -offset indent-two -.Li eric@monet.berkeley.edu -.Ed -.Pp -is normally interpreted from right to left: the message should go to the -ARPA name tables (which do not correspond exactly to the physical ARPANET), -then to the Berkeley gateway, after which it should go to the local host -.Dq Li monet . -When the message reaches -.Li monet , -it is delivered to the user -.Dq Li eric . -.Pp -Unlike some other forms of addressing, this does not imply any routing. -Thus, although this address is specified as an ARPA address, it might -travel by an alternate route if that were more convenient or efficient. -For example, at Berkeley, the associated message would probably go directly -to -.Li monet -over the Ethernet rather than going via the Berkeley ARPANET gateway. -.Ss Abbreviation -.Pp -Under certain circumstances, it may not be necessary to type the entire -domain name. In general, anything following the first dot may be omitted -if it is the same as the domain from which you are sending the message. -For example, a user on -.Dq Li calder.berkeley.edu -could send to -.Dq Li eric@monet -without adding the -.Dq Li berkeley.edu -since it is the same on both sending and receiving hosts. -.Pp -Certain other abbreviations may be permitted as special cases. For -example, at Berkeley, ARPANET hosts may be referenced without adding the -.Dq Li berkeley.edu -as long as their names do not conflict with a local host name. -.Ss Compatibility -.Pp -Certain old address formats are converted to the new format to provide -compatibility with the previous mail system. In particular, -.Bd -ragged -offset indent-two -.Li user@host.ARPA -.Ed -.Pp -is allowed and -.Bd -ragged -offset indent-two -.Li host:user -.Ed -.Pp -is converted to -.Bd -ragged -offset indent-two -.Li user@host -.Ed -.Pp -in order to be consistent with the -.Xr rcp @CMD_EXT@ -command. -.Pp -Also, the syntax -.Bd -ragged -offset indent-two -.Li host!user -.Ed -.Pp -is converted to: -.Bd -ragged -offset indent-two -.Li user@host.UUCP -.Ed -.Pp -This is normally converted back to the -.Dq Li host!user -form before being sent on, for compatibility with older UUCP hosts. -.Pp -The current implementation is not able to route messages automatically through -the UUCP network. Until that time you must explicitly tell the mail system -which hosts to send your message through to get to your final destination. -.Ss Case Distinctions -.Pp -Domain names (i.e., anything after the -.Dq Li @ -sign) may be given in any mixture -of upper and lower case with the exception of UUCP hostnames. Most hosts -accept any combination of case in user names, with the notable exception of -MULTICS sites. -.Ss Route-addrs. -.Pp -Under some circumstances it may be necessary to route a message through -several hosts to get it to the final destination. Normally this routing -is done automatically, but sometimes it is desirable to route the message -manually. Addresses which show these relays are termed -.Dq route-addrs. -These use the syntax: -.Bd -ragged -offset indent-two -.Li <@hosta,@hostb:user@hostc> -.Ed -.Pp -This specifies that the message should be sent to -.Li hosta , -from there to -.Li hostb , -and finally to -.Li hostc . -This path is forced even if there is a more efficient path to -.Li hostc . -.Pp -Route-addrs occur frequently on return addresses, since these are generally -augmented by the software at each host. It is generally possible to ignore -all but the -.Dq Li user@domain -part of the address to determine the actual sender. -.Ss Postmaster -.Pp -Every site is required to have a user or user alias designated -.Dq Li postmaster -to which problems with the mail system may be addressed. -.Ss Other Networks -.Pp -Some other networks can be reached by giving the name of the network as the -last component of the domain. -.Em This is not a standard feature -and may -.Em not -be supported at all sites. For example, messages to CSNET or BITNET sites -can often be sent to -.Dq Li user@host.CSNET -or -.Dq Li user@host.BITNET , -respectively. -.Sh BUGS -The RFC822 group syntax -.Pq Dq Li group:user1,user2,user3; -is not supported except in the special case of -.Dq LI group:; -because of a conflict with old berknet-style addresses. -.Pp -Route-Address syntax is grotty. -.Pp -UUCP- and ARPANET-style addresses do not coexist politely. -.Sh SEE ALSO -.Xr mail @CMD_EXT@ , -.Xr sendmail @SYS_OPS_EXT@ ; -Crocker, D.

Some resource record types may have been standardized in newer RFC's -but not yet implemented in this version of -.Sy BIND . -.Ss SOA Record Format -Each master zone file should begin with an SOA record for the zone. -An example SOA record is as follows: -.Bd -literal -@ IN SOA ucbvax.Berkeley.EDU. rwh.ucbvax.Berkeley.EDU. ( - 1989020501 ; serial - 10800 ; refresh - 3600 ; retry - 3600000 ; expire - 86400 ) ; minimum -.Ed -.Pp -The SOA specifies a serial number, which should be changed each time the -master file is changed. Note that the serial number can be given as a -dotted number, but this is a -.Em very -unwise thing to do since the -translation to normal integers is via concatenation rather than -multiplication and addition. You can spell out the year, month, day of -month, and 0..99 version number and still fit inside the unsigned 32-bit -size of this field. (It's true that we will have to rethink this strategy in -the year 4294, but we're not worried about it.) -.Pp -Secondary servers -check the serial number at intervals specified by the refresh time in -seconds; if the serial number changes, a zone transfer will be done to load -the new data. If a master server cannot be contacted when a refresh is due, -the retry time specifies the interval at which refreshes should be attempted. -If a master server cannot be contacted within the interval given by the -expire time, all data from the zone is discarded by secondary servers. The -minimum value is the cache time-to-live for negative answers (RFC 2308). -.Sh NOTES -The boot file directives -.Dq Li domain -and -.Dq Li suffixes -have been -obsoleted by a more useful, resolver-based implementation of -suffixing for partially-qualified domain names.

There -are entirely new areas of configuration, such as access control lists -and categorized logging. Many options that previously applied to all -zones can now be used selectively. These features, plus a -consideration of future configuration needs led to the creation of a -new configuration file format. - -.Ss General Syntax - -A BIND 8 configuration consists of two general features, statements -and comments. All statements end with a semicolon. Many statements -can contain substatements, which are each also terminated with a -semicolon. - -.Pp -The following statements are supported: -.Bl -tag -width 1 -.It Ic logging -specifies what the server logs, and where the log messages are sent - -.It Ic options -controls global server configuration options and sets defaults for other -statements - -.It Ic zone -defines a zone - -.It Ic acl -defines a named IP address matching list, for access control and other uses - -.It Ic key -specifies key information for use in authentication and authorization - -.It Ic trusted-keys -defines DNSSEC keys that are preconfigured into the server and implicitly -trusted - -.It Ic server -sets certain configuration options for individual remote servers - -.It Ic controls -declares control channels to be used by the -.Nm ndc -utility - -.It Ic include -includes another file - -.El - -The -.Ic logging -and -.Ic options -statements may only occur once per configuration, while the rest may -appear numerous times. Further detail on each statement is provided -in individual sections below. - -Comments may appear anywhere that whitespace may appear in a BIND -configuration file. To appeal to programmers of all kinds, they can -be written in C, C++, or shell/perl constructs. - -C-style comments start with the two characters -.Li /* -(slash, star) and end with -.Li */ -(star, slash). -Because they are completely delimited with these characters, -they can be used to comment only a portion of a line or to span -multiple lines. - -C-style comments cannot be nested. For example, the following is -not valid because the entire comment ends with the first -.Li */ : - -.Bd -literal -offset indent -/* This is the start of a comment. - This is still part of the comment. -/* This is an incorrect attempt at nesting a comment. */ - This is no longer in any comment. */ -.Ed - -C++-style comments start with the two characters -.Li // -(slash, slash) and continue to the end of the physical line. -They cannot be continued across multiple physical lines; to have -one logical comment span multiple lines, each line must use the -.Li // -pair. For example: - -.Bd -literal -offset indent -// This is the start of a comment. The next line -// is a new comment, even though it is logically -// part of the previous comment. -.Ed - -Shell-style (or perl-style, if you prefer) comments start with the -character -.Li # -(hash or pound or number or octothorpe or whatever) and continue to -the end of the physical line, like C++ comments. For example: - -.Bd -literal -offset indent -# This is the start of a comment. The next line -# is a new comment, even though it is logically -# part of the previous comment. -.Ed - -.Em WARNING: -you cannot use the -.Li ; -(semicolon) character to start a comment such as you would in a zone -file. The semicolon indicates the end of a configuration statement, -so whatever follows it will be interpreted as the start of the next -statement. - -.Ss Converting from BIND 4.9.x - -.Pp -BIND 4.9.x configuration files can be converted to the new format -by using -.Pa src/bin/named/named-bootconf , -a shell script that is part of the BIND 8.2.x source kit. - -.Sh DOCUMENTATION DEFINITIONS - -Described below are elements used throughout the BIND configuration -file documentation. Elements which are only associated with one -statement are described only in the section describing that statement. - -.Bl -tag -width 1 -.It Va acl_name -The name of an -.Va address_match_list -as defined by the -.Ic acl -statement. - -.It Va address_match_list -A list of one or more -.Va ip_addr , -.Va ip_prefix , -.Va key_id , -or -.Va acl_name -elements, as described in the -.Sx ADDRESS MATCH LISTS -section. - -.It Va dotted-decimal -One or more integers valued 0 through 255 separated only by dots -(``.''), such as -.Li 123 , -.Li 45.67 -or -.Li 89.123.45.67 . - -.It Va domain_name -A quoted string which will be used as a DNS name, for example -.Qq Li my.test.domain . - -.It Va path_name -A quoted string which will be used as a pathname, such as -.Qq Li zones/master/my.test.domain . - -.It Va ip_addr -An IP address in with exactly four elements in -.Va dotted-decimal -notation. - -.It Va ip_port -An IP port -.Va number . -.Va number is limited to -.Li 0 -through -.Li 65535 , -with values below 1024 typically restricted to -root-owned processes. In some cases an asterisk (``*'') character -can be used as a placeholder to select a random high-numbered port. - -.It Va ip_prefix -An IP network specified in -.Va dotted-decimal -form, followed by ``/'' -and then the number of bits in the netmask. E.g. -.Li 127/8 -is -the network -.Li 127.0.0.0 -with netmask -.Li 255.0.0.0 . -.Li 1.2.3.0/28 -is network -.Li 1.2.3.0 -with netmask -.Li 255.255.255.240. - -.It Va key_name -A string representing the name of a shared key, to be used for transaction -security. - -.It Va number -A non-negative integer with an entire range limited by the range of a -C language signed integer (2,147,483,647 on a machine with 32 bit -integers). Its acceptable value might further be limited by the -context in which it is used. - -.It Va size_spec -A -.Va number , -the word -.Li unlimited , -or the word -.Li default . - -.Pp -The maximum value of -.Va size_spec -is that of unsigned long integers on the machine. -.Li unlimited -requests unlimited use, or the maximum available amount. -.Li default -uses the limit that was in force when the server was started. - -.Pp -A -.Va number -can optionally be followed by a scaling factor: -.Li K -or -.Li k -for kilobytes, -.Li M -or -.Li m -for megabytes, and -.Li G -or -.Li g -for gigabytes, which scale by 1024, 1024*1024, and 1024*1024*1024 -respectively. - -.Pp -Integer storage overflow is currently silently ignored during -conversion of scaled values, resulting in values less than intended, -possibly even negative. Using -.Li unlimited -is the best way to safely set a really large number. - -.It Va yes_or_no -Either -.Li yes -or -.Li no . -The words -.Li true -and -.Li false -are also accepted, as are the numbers -.Li 1 and -.Li 0 . - -.El - -.Sh ADDRESS MATCH LISTS -.Ss Syntax - -.Bd -literal -\fIaddress_match_list\fR = 1\&*\fIaddress_match_element\fR - -\fIaddress_match_element\fR = [ \&"!\&" ] ( \fIaddress_match_list\fR / - \fIip_address\fR / \fIip_prefix\fR / - \fIacl_name\fR / \&"key \&" \fIkey_id\fR ) \&";\&" -.Ed - -.Ss Definition and Usage - -Address match lists are primarily used to determine access control for -various server operations. They are also used to define priorities -for querying other nameservers and to set the addresses on which -.Nm named -will listen for queries. -The elements which constitute an address match list can be any -of the following: - -.Bl -bullet -.It -an -.Va ip-address -(in -.Va dotted-decimal -notation, -.It -an -.Va ip-prefix -(in the '/'-notation), -.It -A -.Va key_id , -as defined by the -.Ic key -statement, -.It -the name of an address match list previously defined with -the -.Ic acl -statement, or -.It -another -.Va address_match_list . -.El - -.Pp -Elements can be negated with a leading exclamation mark (``!''), and -the match list names -.Li any , -.Li none , -.Li localhost -and -.Li localnets -are predefined. More information on those names can be found in the -description of the -.Ic acl -statement. - -.Pp -The addition of the -.Ic key -clause made the name of this syntactic element something of a -misnomer, since security keys can be used to validate access without -regard to a host or network address. Nonetheless, the term ``address -match list'' is still used throughout the documentation. - -.Pp -When a given IP address or prefix is compared to an address match -list, the list is traversed in order until an element matches. The -interpretation of a match depends on whether the list is being used -for access control, defining -.Ic listen-on -ports, or as a topology, and whether the element was -negated. - -.Pp -When used as an access control list, a non-negated match allows access -and a negated match denies access. If there is no match at all in the -list, access is denied. The clauses -.Ic allow-query , -.Ic allow-transfer , -.Ic allow-update , -.Ic allow-recursion , -and -.Ic blackhole -all use address match lists like this. Similarly, the -.Ic listen-on -option will cause the server to not accept queries on any of the -machine's addresses which do not match the list. - -.Pp -When used with the -.Ic topology -option, a non-negated match returns a distance based on its position on -the list (the closer the match is to the start of the list, the -shorter the distance is between it and the server). A negated match -will be assigned the maximum distance from the server. If there is no -match, the address will get a distance which is further than any -non-negated list element, and closer than any negated element. - -.Pp -Because of the first-match aspect of the algorithm, an element that -defines a subset of another element in the list should come before the -broader element, regardless of whether either is negated. For -example, in -.Dl 1.2.3/24; !1.2.3.13 -the 1.2.3.13 element is completely useless, because the algorithm will -match any lookup for 1.2.3.13 to the 1.2.3/24 element. Using -.Dl !1.2.3.13; 1.2.3/24 -fixes that problem by having 1.2.3.13 blocked by the negation but all -other 1.2.3.* hosts fall through. - -.Sh THE LOGGING STATEMENT -.Ss Syntax - -.Bd -literal -logging { - [ channel \fIchannel_name\fR { - ( file \fIpath_name\fR - [ versions ( \fInumber\fR | unlimited ) ] - [ size \fIsize_spec\fR ] - | syslog ( kern | user | mail | daemon | auth | syslog | lpr | - news | uucp | cron | authpriv | ftp | - local0 | local1 | local2 | local3 | - local4 | local5 | local6 | local7 ) - | null ); - - [ severity ( critical | error | warning | notice | - info | debug [ \fIlevel\fR ] | dynamic ); ] - [ print-category \fIyes_or_no\fR; ] - [ print-severity \fIyes_or_no\fR; ] - [ print-time \fIyes_or_no\fR; ] - }; ] - - [ category \fIcategory_name\fR { - \fIchannel_name\fR; [ \fIchannel_name\fR; ... ] - }; ] - ... -}; -.Ed - -.Ss Definition and Usage - -The -.Ic logging -statement configures a wide variety of logging options for the nameserver. -Its -.Ic channel -phrase associates output methods, format options and -severity levels with a name that can then be used with the -.Ic category -phrase to select how various classes of messages are logged. - -.Pp -Only one -.Ic logging -statement is used to define as many channels and categories as are wanted. -If there are multiple logging statements in a configuration, the first -defined determines the logging, and warnings are issued for the -others. If there is no logging statement, the logging configuration -will be: - -.Bd -literal - logging { - category default { default_syslog; default_debug; }; - category panic { default_syslog; default_stderr; }; - category packet { default_debug; }; - category eventlib { default_debug; }; - }; -.Ed - -The logging configuration is established as soon as the -.Ic logging -statement is parsed. If you want to redirect -messages about processing of the entire configuration file, the -.Ic logging -statement must appear first. Even if you do not -redirect configuration file parsing messages, we recommend -always putting the -.Ic logging -statement first so that this rule need not be consciously recalled if -you ever do need want the parser's messages relocated. - -.Ss The channel phrase - -All log output goes to one or more ``channels''; you can make as many -of them as you want. - -.Pp -Every channel definition must include a clause that says whether -messages selected for the channel go to a file, to a particular syslog -facility, or are discarded. It can optionally also limit the message -severity level that will be accepted by the channel (default is -.Li info ) , -and whether to include a time stamp generated by -.Nm named , -the category name, or severity level. The default is not to include -any of those three. - -.Pp -The word -.Li null -as the destination option for the -channel will cause all messages sent to it to be discarded; other -options for the channel are meaningless. - -.Pp -The -.Ic file -clause can include limitations both on how -large the file is allowed to become, and how many versions of the file -will be saved each time the file is opened. - -.Pp -The -.Ic size -option for files is simply a hard ceiling on -log growth. If the file ever exceeds the size, then -.Nm named -will just not write anything more to it until the file is reopened; -exceeding the size does not automatically trigger a reopen. The -default behavior is to not limit the size of the file. - -.Pp -If you use the -.Ic version -logfile option, then -.Nm named -will retain that many backup versions of the file -by renaming them when opening. For example, if you choose to keep 3 -old versions of the file lamers.log then just before it is opened -lamers.log.1 is renamed to lames.log.2, lamers.log.0 is renamed to -lamers.log.1, and lamers.log is renamed to lamers.log.0. No rolled -versions are kept by default; any existing log file is simply appended. -The -.Li unlimited -keyword is synonymous with -.Li 99 -in current BIND releases. Example usage of size and versions options: - -.Bd -literal - channel an_example_level { - file "lamers.log" versions 3 size 20m; - print-time yes; - print-category yes; - }; -.Ed - -.Pp -The argument for the -.Ic syslog -clause is a syslog facility as described in the -.Xr syslog 3 -manual page. How -.Nm syslogd -will handle messages sent to this facility is described in the -.Xr syslog.conf 5 -manual page. If you have a system which uses a very old version of -syslog that only uses two arguments to the -.Fn openlog() -function, then this clause is silently ignored. - -.Pp -The -.Ic severity -clause works like syslog's ``priorities'', except that they can also be -used if you are writing straight to a file rather than using -syslog. Messages which are not at least of the severity level given -will not be selected for the channel; messages of higher severity -levels will be accepted. - -.Pp -If you are using syslog, then the -.Pa syslog.conf -priorities will also determine what eventually passes through. -For example, defining a channel facility and severity as -.Li daemon -and -.Li debug -but only logging -.Li daemon.warning -via -.Pa syslog.conf -will cause messages of severity -.Li info -and -.Li notice -to be dropped. If the situation were reversed, with -.Nm named -writing messages of only -.Li warning -or higher, then -.Nm syslogd -would print all messages it received from the channel. - -.Pp -The server can supply extensive debugging information when it is in -debugging mode. If the server's global debug level is greater than -zero, then debugging mode will be active. The global debug level is -set either by starting the -.Nm named -server with the -.Fl d -flag followed by a positive integer, or by sending the running server the -.Dv SIGUSR1 -signal (for example, by using -.Ic ndc trace ) . -The global debug level can be set to -zero, and debugging mode turned off, by sending the server the -.Dv SIGUSR2 -signal (as with -.Ic ndc notrace ) . -All debugging messages in the server have a -debug level, and higher debug levels give more more detailed output. -Channels that specify a specific debug severity, e.g. - -.Bd -literal - channel specific_debug_level { - file \&"foo\&"; - severity debug 3; - }; -.Ed - -will get debugging output of level 3 or less any time the -server is in debugging mode, regardless of the global debugging level. -Channels with -.Li dynamic -severity use the server's global level to determine what messages to -print. - -.Pp -If -.Ic print-time -has been turned on, then the date and time will be logged. -.Ic print-time -may be specified for a syslog channel, but is usually pointless since -syslog also prints the date and time. -If -.Ic print-category -is requested, then the category of the message will be logged as well. -Finally, if -.Ic print-severity -is on, then the severity level of the message will be logged. The -.Ic print- -options may be used -in any combination, and will always be printed in the following order: -time, category, severity. Here is an example where all three -.Ic print- -options are on: - -.Bd -literal - 28-Apr-1997 15:05:32.863 default: notice: Ready to answer queries. -.Ed - -.Pp -There are four predefined channels that are used for -.Nm named 's -default logging as follows. How they are used -used is described in the next section, -.Sx The category phrase. - -.Bd -literal - channel default_syslog { - syslog daemon; # send to syslog's daemon facility - severity info; # only send priority info and higher - }; - - channel default_debug { - file \&"named.run\&"; # write to named.run in the working directory - # Note: stderr is used instead of \&"named.run\&" - # if the server is started with the -f option. - severity dynamic; # log at the server's current debug level - }; - - channel default_stderr { # writes to stderr - file \&"<stderr>\&"; # this is illustrative only; there's currently - # no way of specifying an internal file - # descriptor in the configuration language. - severity info; # only send priority info and higher - }; - - channel null { - null; # toss anything sent to this channel - }; -.Ed - -Once a channel is defined, it cannot be redefined. Thus you cannot -alter the built-in channels directly, but you can modify the default -logging by pointing categories at channels you have defined. - -.Ss The category phrase - -There are many categories, so you can send the logs you want to see -wherever you want, without seeing logs you don't want. If you don't -specify a list of channels for a category, then log messages in that -category will be sent to the -.Li default -category instead. -If you don't specify a default category, the following ``default -default'' is used: - -.Bd -literal - category default { default_syslog; default_debug; }; -.Ed - -As an example, let's say you want to log security events to a file, -but you also want keep the default logging behavior.

This statement may appear at only once in a -configuration file; if more than one occurrence is found, the -first occurrence determines the actual options used, -and a warning will be generated. If there is no options statement, -an options block with each option set to its default will be used. - -.Ss Pathnames - -.Bl -tag -width 1 - -.It Ic version -The version the server should report via the ndc command or via a query of -name -.Pa version.bind -in class chaos. The default is the real version number of ths server, -but some server operators prefer the string ( -.Ic surely you must be joking -). - -.It Ic directory -The working directory of the server. Any non-absolute -pathnames in the configuration file will be taken as relative to this -directory. The default location for most server output files -(e.g. -.Pa named.run ) -is this directory. If a directory is not -specified, the working directory defaults to -.Pa . , -the directory from which the -server was started. The directory specified should be an absolute path. - -.It Ic named-xfer -The pathname to the named-xfer program that the server uses for -inbound zone transfers. If not specified, the default is -system dependent (e.g. -.Pa /usr/sbin/named-xfer -). - -.It Ic dump-file -The pathname of the file the server dumps the database to when it -receives -.Dv SIGINT -signal (as sent by -.Ic ndc dumpdb -). If not specified, the default is -.Pa named_dump.db . - -.It Ic memstatistics-file -The pathname of the file the server writes memory usage statistics to -on exit, if -.Ic deallocate-on-exit -is -.Li yes . -If not specified, the default is -.Pa named.memstats . - -.It Ic pid-file -The pathname of the file the server writes its process ID in. If not -specified, the default is operating system dependent, but is usually -.Pa /var/run/named.pid -or -.Pa /etc/named.pid . -The pid-file is used by programs like -.Nm ndc -that want to send signals to the running nameserver. - -.It Ic statistics-file -The pathname of the file the server appends statistics to when it -receives -.Dv SIGILL -signal (from -.Ic ndc stats ) . -If not specified, the default is -.Pa named.stats . -.El - -.Ss Boolean Options - -.Bl -tag -width 1 -.It Ic auth-nxdomain -If -.Li yes , -then the -.Li AA -bit is always set on -.Dv NXDOMAIN -responses, even if the server is not actually authoritative. -The default is -.Li yes . -Do not turn off -.Ic auth-nxdomain -unless you are sure you know what you are -doing, as some older software won't like it. - -.It Ic deallocate-on-exit -If -.Li yes , -then when the server exits it will painstakingly deallocate every -object it allocated, and then write a memory usage report to the -.Ic memstatistics-file . -The default is -.Li no , -because it is faster to let the operating system clean up. -.Ic deallocate-on-exit -is handy for detecting memory leaks. - -.It Ic dialup -If -.Li yes , -then the server treats all zones as if they are doing zone transfers -across a dial on demand dialup link, which can be brought up by -traffic originating from this server. This has different effects -according to zone type and concentrates the zone maintenance so that -it all happens in a short interval, once every -.Ic heartbeat-interval -and hopefully during the one call. -It also suppresses some of the normal zone maintenance traffic. -The default is -.Li no . -The -.Ic dialup -option may also be specified in the -.Ic zone -statement, in which -case it overrides the -.Ic options dialup -statement. - -.Pp -If the zone is a -.Ic master -then the server will send out -.Dv NOTIFY -request to all the slaves. -This will trigger the zone up to date checking in the slave (providing -it supports -.Dv NOTIFY ) -allowing the slave -to verify the zone while the call us up. - -.Pp -If the zone is a -.Ic slave -or -.Ic stub -then the server will suppress the zone regular zone up to date queries -and only perform the when the -.Ic heartbeat-interval -expires. - -.It Ic fake-iquery -If -.Li yes , -the server will simulate the obsolete DNS query type -.Dv IQUERY . -The default is -.Li no . - -.It Ic fetch-glue -If -.Li yes -(the default), the server will fetch ``glue'' resource -records it doesn't have when constructing the additional data section of -a response. -.Ic fetch-glue no -can be used in conjunction with -.Ic recursion no -to prevent the server's cache from growing or -becoming corrupted (at the cost of requiring more work from the client). - -.It Ic has-old-clients -Setting the option to -.Li yes , -is equivalent to setting the following three options: -.Ic auth-nxdomain yes ;, -.Ic maintain-ixfr-base yes ;, -and -.Ic rfc2308-type1 no ; -. The use of -.Ic has-old-clients -with -.Ic auth-nxdomain , -.Ic maintain-ixfr-base , -and -.Ic rfc2308-type1 -is order dependant. - -.It Ic host-statistics -If -.Li yes , -then statistics are kept for every host that the the nameserver -interacts with. The default is -.Li no . -.Em Note: -turning on -.Ic host-statistics -can consume huge amounts of memory. - -.It Ic maintain-ixfr-base -If -.Li yes , -statistics are kept for every host that the nameserver interacts with. The default is -.Li no . -.Em Note: -turning on -.Li host-statistics -can consume huge amounts of memory. - -.It Ic multiple-cnames -If -.Li yes , -then multiple CNAME resource records will be -allowed for a domain name. The default is -.Li no . -Allowing multiple CNAME records is against standards and is not recommended. -Multiple CNAME support is available because previous versions of BIND -allowed multiple CNAME records, and these records have been used for load -balancing by a number of sites. - -.It Ic notify -If -.Li yes -(the default), DNS NOTIFY messages are sent when a -zone the server is authoritative for changes. The use of NOTIFY -speeds convergence between the master and its slaves. Slave servers -that receive a NOTIFY message and understand it will contact the -master server for the zone and see if they need to do a zone transfer, and -if they do, they will initiate it immediately. The -.Ic notify -option may also be specified in the -.Ic zone -statement, in which case it overrides the -.Ic options notify -statement. - -.It Ic recursion -If -.Li yes , -and a DNS query requests recursion, then the -server will attempt to do all the work required to answer the query. -If recursion is not on, the server will return a referral to the -client if it doesn't know the answer. The default is -.Li yes . -See also -.Ic fetch-glue -above. - -.It Ic rfc2308-type1 -If -.Li yes, -the server will send NS records along with the SOA record for negative -answers. You need to set this to no if you have an old BIND server using -you as a forwarder that does not understand negative answers which contain -both SOA and NS records or you have an old version of sendmail. The correct -fix is to upgrade the broken server or sendmail. The default is -.Li no . - -.It Ic use-id-pool -If -.Li yes, -the server will keep track of its own outstanding query ID's to avoid duplication -and increase randomness. This will result in 128KB more memory being consumed -by the server. The default is -.Li no . - -.It Ic treat-cr-as-space -If -.Li yes, -the server will treat CR characters the same way it treats a space -or tab. This may be necessary when loading zone files on a UNIX system -that were generated on an NT or DOS machine. The default is -.Li no . - - -.El - -.Ss Also-Notify - -.Ic also-notify - -Defines a global list of IP addresses that also get sent NOTIFY messages -whenever a fresh copy of the zone is loaded. This helps to ensure that copies of -the zones will quickly converge on ``stealth'' servers. If an -.Ic also-notify -list is given in a -.Ic zone -statement, it will override the -.Ic options also-notify -statement. When a -.Ic zone notify -statement is set to -.Ic no , -the IP addresses in -the global -.Ic also-notify -list will not get sent NOTIFY messages for that zone. -The default is the empty list (no global notification list). - -.Ss Forwarding - -.Pp -The forwarding facility can be used to create a large site-wide -cache on a few servers, reducing traffic over links to external -nameservers. It can also be used to allow queries by servers that do -not have direct access to the Internet, but wish to look up exterior -names anyway. Forwarding occurs only on those queries for which the -server is not authoritative and does not have the answer in its cache. - -.Bl -tag -width 1 -.It Ic forward -This option is only meaningful if the -.Ic forwarders -list is -not empty. A value of -.Li first , -the default, causes the -server to query the forwarders first, and if that doesn't answer the -question the server will then look for the answer itself. If -.Li only -is specified, the server will only query the forwarders. - -.It Ic forwarders -Specifies the IP addresses to be used for forwarding. The default is the -empty list (no forwarding). -.El - -.Pp -Forwarding can also be configured on a per-zone basis, allowing for -the global forwarding options to be overridden in a variety of ways. -You can set particular zones to use different forwarders, or have -different -.Ic forward only/first -behavior, or to not forward -at all. See -.Sx THE ZONE STATEMENT -section for more information. - -.Pp -Future versions of BIND 8 will provide a more powerful forwarding -system. The syntax described above will continue to be supported. - -.Ss Name Checking - -The server can check domain names based upon their expected client contexts. -For example, a domain name used as a hostname can be checked for compliance -with the RFCs defining valid hostnames. - -.Pp -Three checking methods are available: - -.Bl -tag -width 1 -.It Ic ignore -No checking is done. - -.It Ic warn -Names are checked against their expected client contexts. Invalid names are -logged, but processing continues normally. - -.It Ic fail -Names are checked against their expected client contexts. Invalid names are -logged, and the offending data is rejected. -.El - -.Pp -The server can check names three areas: master zone files, slave -zone files, and in responses to queries the server has initiated. If -.Ic check-names response fail -has been specified, and -answering the client's question would require sending an invalid name -to the client, the server will send a -.Dv REFUSED -response code to the client. - -.Pp -The defaults are: - -.Bd -literal - check-names master fail; - check-names slave warn; - check-names response ignore; -.Ed - -.Pp -.Ic check-names -may also be specified in the -.Ic zone -statement, in which case it overrides the -.Ic options check-names -statement. When used in a -.Ic zone -statement, the area is not specified (because it can be deduced from -the zone type). - -.Ss Access Control - -.Pp -Access to the server can be restricted based on the IP address of the -requesting system or via shared secret keys. See -.Sx ADDRESS MATCH LISTS -for details on how to specify access criteria. - -.Bl -tag -width 1 -.It Ic allow-query -Specifies which hosts are allowed to ask ordinary questions. -.Ic allow-query -may also be specified in the -.Ic zone -statement, in which case it overrides the -.Ic options allow-query -statement. If not specified, the default is - -.Bl -tag -width 1 -.It Ic allow-recursion -Specifies which hosts are allowed to ask recursive questions. -.Ic allow-recursion -may also be specified in the -.Ic zone -statement, in which case it overrides the -.Ic options allow-recursion -statement. If not specified, the default is to allow recursive queries -from all hosts. - -.It Ic allow-transfer -Specifies which hosts are allowed to receive zone transfers from the -server. -.Ic allow-transfer -may also be specified in the -.Ic zone -statement, in which case it overrides the -.Ic options allow-transfer -statement. If not specified, the default -is to allow transfers from all hosts. - -.It Ic blackhole -Specifies a list of addresses that the server will not accept queries from -or use to resolve a query. Queries from these addresses will not be -responded to. -.El - -.Ss Interfaces - -.Pp -The interfaces and ports that the server will answer queries from may -be specified using the -.Ic listen-on -option. -.Ic listen-on -takes an optional port, and an address match list. -The server will listen on all interfaces allowed by the address match -list. If a port is not specified, port 53 will be used. - -.Pp -Multiple -.Ic listen-on -statements are allowed. For example, - -.Bd -literal - listen-on { 5.6.7.8; }; - listen-on port 1234 { !1.2.3.4; 1.2/16; }; -.Ed - -will enable the nameserver on port 53 for the IP address 5.6.7.8, and -on port 1234 of an address on the machine in net 1.2 that is not -1.2.3.4. - -.Pp -If no -.Ic listen-on -is specified, the server will listen on port -53 on all interfaces. - -.Ss Query Address - -.Pp -If the server doesn't know the answer to a question, it will query -other nameservers. -.Ic query-source -specifies the address and port used for such queries. If -.Ic address -is -.Li * -or is omitted, a wildcard IP address -( -.Dv INADDR_ANY ) -will be used. If -.Va port -is -.Li * -or is omitted, a random unprivileged port will be used. -The default is -.Dl query-source address * port *; - -.Pp -Note: -.Ic query-source -currently applies only to UDP queries; -TCP queries always use a wildcard IP address and a random unprivileged -port. - -.Ss Zone Transfers - -.Bl -tag -width 1 -.It Ic max-transfer-time-in -Inbound zone transfers ( -.Nm named-xfer -processes) running -longer than this many minutes will be terminated. -The default is 120 minutes (2 hours). - -.It Ic transfer-format -The server supports two zone transfer methods. -.Li one-answer -uses one DNS message per resource record -transferred. -.Li many-answers -packs as many resource records -as possible into a message. -.Li many-answers -is more efficient, but is only known to be understood by BIND 8.1 and -patched versions of BIND 4.9.5. The default is -.Li one-answer . -.Ic transfer-format -may be overridden on a per-server basis by using the -.Ic server -statement. - -.It Ic transfers-in -The maximum number of inbound zone transfers that can be running -concurrently. The default value is 10. Increasing -.Ic transfers-in -may speed up the convergence of slave zones, -but it also may increase the load on the local system. - -.It Ic transfers-out -This option will be used in the future to limit the number of -concurrent outbound zone transfers. It is checked for syntax, but is -otherwise ignored. - -.It Ic transfers-per-ns -The maximum number of inbound zone transfers ( -.Nm named-xfer -processes) that can be concurrently transferring from a given remote -nameserver. The default value is 2. Increasing -.Ic transfers-per-ns -may speed up the convergence of slave zones, but it also may increase -the load on the remote nameserver. -.Ic transfers-per-ns -may be overridden on a per-server basis by using the -.Ic transfers -phrase of the -.Ic server -statement. - -.It Ic transfer-source -.Nm transfer-source -determines which local address will be bound to the TCP connection used to fetch all zones -transferred inbound by the server. If not set, it defaults to a system controlled value which will usually be the address of the interface ``closest to`` the remote end. This -address must appear in the remote end's -.Nm allow-transfer -option for the zones being transferred, if one is specified. This statement sets the -.Nm transfer-source -for all zones, but can be overriden on a per-zone basis by includinga -.Nm transfer-source -statement within the zone block in the configuration file. -.El - -.Ss Resource Limits - -.Pp -The server's usage of many system resources can be limited. Some -operating systems don't support some of the limits. On such systems, -a warning will be issued if the unsupported limit is used. Some -operating systems don't support limiting resources, and on these systems -a -.D1 cannot set resource limits on this system -message will -be logged. - -.Pp -Scaled values are allowed when specifying resource limits. For -example, -.Li 1G -can be used instead of -.Li 1073741824 -to specify a limit of one gigabyte. -.Li unlimited -requests unlimited use, or the maximum -available amount. -.Li default -uses the limit that was in -force when the server was started. -See the definition of -.Va size_spec -in the -.Sx DOCUMENTATION DEFINITIONS -section for more details. - -.Bl -tag -width 1 -.It Ic coresize -The maximum size of a core dump. The default value is -.Li default . - -.It Ic datasize -The maximum amount of data memory the server may use. The default -value is -.Li default . - -.It Ic files -The maximum number of files the server may have open concurrently. -The default value is -.Li unlimited . -Note that on some operating systems the server cannot set an unlimited -value and cannot determine the maximum number of open files the kernel -can support. On such systems, choosing -.Li unlimited -will cause the server to use -the larger of the -.Va rlim_max -from -.Fn getrlimit RLIMIT_NOFILE -and the value returned by -.Fn sysconf _SC_OPEN_MAX . -If the -actual kernel limit is larger than this value, use -.Ic limit files -to specify the limit explicitly. - -.It Ic max-ixfr-log-size -The -.Li max-ixfr-log-size -will be used in a future release of the server to limit the size of the transaction -log kept for Incremental Zone Transfer. - -.It Ic stacksize -The maximum amount of stack memory the server may use. The default value is -.Li default . -.El - -.Ss Periodic Task Intervals - -.Bl -tag -width 1 -.It Ic cleaning-interval -The server will remove expired resource records from the cache every - -.Ic cleaning-interval -minutes. The default is 60 minutes. If set -to 0, no periodic cleaning will occur. - -.It Ic heartbeat-interval -The server will perform zone maintenance tasks for all zones marked -.Ic dialup yes -whenever this interval expires. -The default is 60 minutes. Reasonable values are up to 1 day (1440 minutes). -If set to 0, no zone maintenance for these zones will occur. - -.It Ic interface-interval -The server will scan the network interface list every -.Ic interface-interval -minutes. The default is 60 minutes. -If set to 0, interface scanning will only occur when the configuration -file is loaded. After the scan, listeners will be started on any new -interfaces (provided they are allowed by the -.Ic listen-on -configuration). Listeners on interfaces that have gone away will be -cleaned up. - -.It Ic statistics-interval -Nameserver statistics will be logged every -.Ic statistics-interval -minutes. The default is 60. If set to 0, no statistics will be logged. -.El - -.Ss Topology - -.Pp -All other things being equal, when the server chooses a nameserver -to query from a list of nameservers, it prefers the one that is -topologically closest to itself. The -.Ic topology -statement takes an address match list and interprets it in a special way. -Each top-level list element is assigned a distance. -Non-negated elements get a distance based on -their position in the list, where the closer the match is to the start -of the list, the shorter the distance is between it and the server. A -negated match will be assigned the maximum distance from the server. -If there is no match, the address will get a distance which is further -than any non-negated list element, and closer than any negated -element. For example, - -.Bd -literal - topology { - 10/8; - !1.2.3/24; - { 1.2/16; 3/8; }; - }; -.Ed - -will prefer servers on network 10 the most, followed by hosts on -network 1.2.0.0 (netmask 255.255.0.0) and network 3, with the exception -of hosts on network 1.2.3 (netmask 255.255.255.0), which is preferred least -of all. - -.Pp -The default topology is -.Dl topology { localhost; localnets; }; - -.Ss Resource Record sorting - -.Pp -When returning multiple RRs, the nameserver will normally return them in -.Ic Round Robin , -i.e. after each request, the first RR is put to the end of the list. -As the order of RRs is not defined, this should not cause any problems. - -The client resolver code should re-arrange the RRs as appropriate, i.e. using -any addresses on the local net in preference to other addresses. However, not all -resolvers can do this, or are not correctly configured. - -When a client is using a local server, the sorting can be performed in the server, -based on the client's address. This only requires configuring the nameservers, -not all the clients. - -The -.Ic sortlist -statement takes an address match list and interprets it even more -specially than the -.Ictopology -statement does. - -Each top level statement in the sortlist must itself be an explicit address match -list with one or two elements. The first element (which may be an IP address, -an IP prefix, an ACL name or nested address match list) of each top level list is -checked against the source address of the query until a match is found. - -Once the source address of the query has been matched, if the top level -statement contains only one element, the actual primitive element that -matched the source address is used to select the address in the response to -move to the beginning of the response. If the statement is a list of two elements, -the second element is treated like the address match list in a topology -statement. Each top level element is assigned a distance and the address in the -response with the minimum distance is moved to the beginning of the response. - -In the following example, any queries received from any of the addresses of the -host itself will get responses preferring addresses on any of the locally -connected networks. Next most preferred are addresses on the 192.168.1/24 -network, and after that either the 192.168.2/24 or 192.168.3/24 network with no -preference shown between these two networks. Queries received from a host on -the 192.168.1/24 network will prefer other addresses on that network to the -192.168.2/24 and 192.168.3/24 networks. Queries received from a host on the -192.168.4/24 or the 192.168.5/24 network will only prefer other addresses on -their directly connected networks. - -.Bd -literal -sortlist { - { localhost; // IF the local host - { localnets; // THEN first fit on the - 192.168.1/24; // following nets - { 192,168.2/24; 192.168.3/24; }; }; }; - { 192.168.1/24; // IF on class C 192.168.1 - { 192.168.1/24; // THEN use .1, or .2 or .3 - { 192.168.2/24; 192.168.3/24; }; }; }; - { 192.168.2/24; // IF on class C 192.168.2 - { 192.168.2/24; // THEN use .2, or .1 or .3 - { 192.168.1/24; 192.168.3/24; }; }; }; - { 192.168.3/24; // IF on class C 192.168.3 - { 192.168.3/24; // THEN use .3, or .1 or .2 - { 192.168.1/24; 192.168.2/24; }; }; }; - { { 192.168.4/24; 192.168.5/24; }; // if .4 or .5, prefer that net - }; -}; -.Ed - -The following example will give reasonable behaviour for the local host and -hosts on directly connected networks. It is similar to the behavior of the -address sort in BIND 4.9.x. Responses sent to queries from the local host will -favor any of the directly connected networks. Responses sent to queries from -any other hosts on a directly connected network will prefer addresses on that -same network. Responses to other queries will not be sorted. - -.Bd -literal -sortlist { - { localhost; localnets; }; - { localnets; }; -}; -.Ed - -.Ss RRset Ordering - -.Pp -When multiple records are returned in an answer it may be useful to configure -the order the records are placed into the response. For example the records for -a zone might be configured to always be returned in the order they are defined -in the zone file.

The specification of options in such a zone will override -any global options declared in the -.Ic options -statement. - -.Pp -If either no -.Ic forwarders -clause is present in the zone or an empty list for -.Ic forwarders -is given, then no forwarding will be done for the zone, cancelling the -effects of any -.Ic forwarders -in the -.Ic options -statement. -Thus if you want to use this type of zone to change only the behavior of -the global -.Ic forward -option, and not the servers used, then you also need to respecify the -global forwarders. - -.It Ic hint -The initial set of root nameservers is specified using a -.Ic hint -zone. When the server starts up, it uses the root hints -to find a root nameserver and get the most recent list of root nameservers. -.El - -.Pp -Note: previous releases of BIND used the term -.Ic primary -for a master zone, -.Ic secondary -for a slave zone, and -.Ic cache -for a hint zone. - -.Ss Classes - -The zone's name may optionally be followed by a class.

Internet domain name servers. -.Pp -State information is kept in -.Fa statp -and is used to control the behavior of these functions. -.Fa statp -should be set to all zeros prior to the first call to

res_mkquery , -.Fn res_send , -.Fn res_update , -.Fn res_close -and -.Fn herror -are deprecated and are supplied for compatability with old source -code. -They use global configuration and state information that is -kept in the structure -.Ft _res -rather than that referenced through -.Ft statp . -.Pp -Most of the values in -.Ft statp -and -.Ft _res -are initialized on the first call to -.Fn res_ninit -/ -.Fn res_init -to reasonable defaults and can be ignored. -Options -stored in -.Ft statp->options -/ -.Ft _res.options -are defined in -.Pa resolv.h -and are as follows. -Options are stored as a simple bit mask containing the bitwise -.Dq OR -of the options enabled. -.Bl -tag -width "RES_DEB" -.It Dv RES_INIT -True if the initial name server address and default domain name are -initialized (i.e., -.Fn res_ninit -/ -.Fn res_init -has been called). -.It Dv RES_DEBUG -Print debugging messages. -.It Dv RES_AAONLY -Accept authoritative answers only. -should continue until it finds an authoritative answer or finds an error. -Currently this is not implemented. -.It Dv RES_USEVC -Use TCP connections for queries instead of UDP datagrams. -.It Dv RES_STAYOPEN -Used with -.Dv RES_USEVC -to keep the TCP connection open between queries. -This is useful only in programs that regularly do many queries. -UDP should be the normal mode used. -.It Dv RES_IGNTC -Ignore truncation errors, i.e., don't retry with TCP. -.It Dv RES_RECURSE -Set the recursion-desired bit in queries. -This is the default. -(\c -.Fn res_nsend -/ -.Fn res_send -does not do iterative queries and expects the name server -to handle recursion.) -.It Dv RES_DEFNAMES -If set, -.Fn res_nsearch -/ -.Fn res_search -will append the default domain name to single-component names -(those that do not contain a dot). -This option is enabled by default. -.It Dv RES_DNSRCH -If this option is set, -.Fn res_nsearch -/ -.Fn res_search -will search for host names in the current domain and in parent domains; see -.Xr hostname @DESC_EXT@ . -This is used by the standard host lookup routine -.Xr gethostbyname @LIB_NETWORK_EXT@ . -This option is enabled by default. -.It Dv RES_NOALIASES -This option turns off the user level aliasing feature controlled by -the -.Ev HOSTALIASES -environment variable. -Network daemons should set this option. -.It Dv RES_USE_INET6 -This option causes -.Xr gethostbyname @LIB_NETWORK_EXT@ -to look for AAAA records before looking for A records if none are found. -.It Dv RES_ROTATE -This options causes the -.Fn res_nsend -/ -.Fn res_send -to rotate the list of nameservers in -.Fa statp->nsaddr_list -/ -.Fa _res.nsaddr_list . -.It Dv RES_KEEPTSIG -This option causes -.Fn res_nsendsigned -to leave the message unchanged after TSIG verification; otherwise the TSIG -record would be removed and the header updated. -.El -.Pp -The -.Fn res_ninit -/ -.Fn res_init -routine -reads the configuration file (if any; see -.Xr resolver @FORMAT_EXT@ ) -to get the default domain name, search list and -the Internet address of the local name server(s). -If no server is configured, the host running the resolver is tried. -The current domain name is defined by the hostname -if not specified in the configuration file; -it can be overridden by the environment variable -.Ev LOCALDOMAIN . -This environment variable may contain several blank-separated -tokens if you wish to override the -.Dq search list -on a per-process basis. This is similar to the -.Ic search -command in the configuration file. -Another environment variable -.Pq Dq Ev RES_OPTIONS -can be set to override certain internal resolver options which are otherwise -set by changing fields in the -.Ft statp -/ -.Ft _res -structure or are inherited from the configuration file's -.Ic options -command. The syntax of the -.Dq Ev RES_OPTIONS -environment variable is explained in -.Xr resolver @FORMAT_EXT@ . -Initialization normally occurs on the first call -to one of the other resolver routines. -.Pp -The -.Fn res_nquery -/ -.Fn res_query -functions provides interfaces to the server query mechanism. -They constructs a query, sends it to the local server, -awaits a response, and makes preliminary checks on the reply. -The query requests information of the specified -.Fa type -and -.Fa class -for the specified fully-qualified domain name -.Fa dname . -The reply message is left in the -.Fa answer -buffer with length -.Fa anslen -supplied by the caller. -.Fn res_nquery -/ -.Fn res_query -return -1 on error or the length of the answer. -.Pp -The -.Fn res_nsearch -/ -.Fn res_search -routines make a query and awaits a response like -.Fn res_nquery -/ -.Fn res_query , -but in addition, it implements the default and search rules -controlled by the -.Dv RES_DEFNAMES -and -.Dv RES_DNSRCH -options. -It returns the length of the first successful reply which is stored in -.Ft answer -or -1 on error. -.Pp -The remaining routines are lower-level routines used by -.Fn res_nquery -/ -.Fn res_query . -The -.Fn res_nmkquery -/ -.Fn res_mkquery -functions -constructs a standard query message and places it in -.Fa buf . -It returns the size of the query, or \-1 if the query is -larger than -.Fa buflen . -The query type -.Fa op -is usually -.Dv QUERY , -but can be any of the query types defined in -.Pa <arpa/nameser.h> . -The domain name for the query is given by -.Fa dname . -.Fa Newrr -is currently unused but is intended for making update messages. -.Pp -The -.Fn res_nsend -/ -.Fn res_send -/ -.Fn res_nsendsigned -routines -sends a pre-formatted query and returns an answer. -It will call -.Fn res_ninit -/ -.Fn res_init -if -.Dv RES_INIT -is not set, send the query to the local name server, and -handle timeouts and retries. Additionally, -.Fn res_nsendsigned -will use TSIG signatures to add authentication to the query and verify the -response. In this case, only one nameserver will be contacted. -The length of the reply message is returned, or \-1 if there were errors. -.Pp -.Fn res_nquery -/ -.Fn res_query , -.Fn res_nsearch -/ -.Fn res_search -and -.Fn res_nsend -/ -.Fn res_send -return a length that may be bigger than -.Fa anslen . -In that case the query should be retried with a bigger buffer. -NOTE the answer to the second query may be larger still so supplying -a buffer that bigger that the answer returned by the previous -query is recommended. -.Pp -.Fa answer -MUST be big enough to receive a maximum UDP response from the server or -parts of the answer will be silently discarded. -The default maximum UDP response size is 512 bytes. -.Pp -The functions -.Fn res_nisourserver -/ -.Fn res_isourserver -return true when -.Fa inp -is one of the servers in -.Fa statp->nsaddr_list -/ -.Fa _res.nsaddr_list . -.Pp -The functions -.Fn res_npquery -/ -.Fn p_nquery -/ -.Fn p_query -print out the query and any answer in -.Fa msg -on -.Fa fp . -.Fn p_query -is equivalent to -.Fn p_nquery -with -.Fa msglen -set to 512. -.Pp -The function -.Fn fp_resstat -prints out the active flag bits in -.Fa statp->options -preceeded by the text ";; res options:" on -.Fa file . -.Pp -The functions -.Fn res_hostalias -/ -.Fn hostalias -lookup up name in the file referred to by the -.Ev HOSTALIASES files return a fully qualified hostname if found or NULL if -not found or an error occurred. -.Fn res_hostalias -uses -.Fa buf -to store the result in, -.Fn hostalias -uses a static buffer. -.Pp -The functions -.Fn res_nupdate -/ -.Fn res_update -take a list of ns_updrec -.Fa rrecp_in . -Identifies the containing zone for each record and groups the records -according to containing zone maintaining in zone order then sends and -update request to the servers for these zones. -The number of zones updated is returned or -1 on error. -.Pp -The function -.Fn res_findzonecut -discovers the closest enclosing zone cut for a specified domain name, -and finds the IP addresses of the zone's master servers. -.Pp -The function -.Fn res_nsendupdate -is used to perform TSIG authenticated dynamic update operations. -.Fn res_nsendupdate -sends a dynamic update to the specified IP address, authenticating the update -if the key is not NULL. -.Pp -The functions -.Fn res_nmkupdate -/ -.Fn res_mkupdate -take a linked list of ns_updrec -.Fa rrecp_in -and construct a UPDATE message in -.Fa buf . -.Fn res_nmkupdate -/ -.Fn res_mkupdate -return the length of the constructed message on no error or one of the -following error values. -.Bl -inset -width "-5" -.It -1 -An error occurred parsing -.Fa rrecp_in . -.It -2 -The buffer -.Fa buf -was too small. -.It -3 -The first record was not a zone section or there was a section order problem. -The section order is S_ZONE, S_PREREQ and S_UPDATE. -.It -4 -A number overflow occurred. -.It -5 -Unknown operation or no records. -.El -.Pp -The functions -.Fn res_nclose -/ -.Fn res_close -close any open files referenced through -.Fa statp -/ -.Fa _res . -.Pp -The -.Fn dn_comp -function -compresses the domain name -.Fa exp_dn -and stores it in -.Fa comp_dn . -The size of the compressed name is returned or \-1 if there were errors. -The size of the array pointed to by -.Fa comp_dn -is given by -.Fa length . -The compression uses -an array of pointers -.Fa dnptrs -to previously-compressed names in the current message. -The first pointer points to -to the beginning of the message and the list ends with -.Dv NULL . -The limit to the array is specified by -.Fa lastdnptr . -A side effect of -.Fn dn_comp -is to update the list of pointers for labels inserted into the message -as the name is compressed. If -.Fa dnptr -is -.Dv NULL , -names are not compressed. If -.Fa lastdnptr -is -.Dv NULL , -the list of labels is not updated. -.Pp -The -.Fn dn_expand -entry -expands the compressed domain name -.Fa comp_dn -to a full domain name. -The compressed name is contained in a query or reply message; -.Fa msg -is a pointer to the beginning of the message. -The uncompressed name is placed in the buffer indicated by -.Fa exp_dn -which is of size -.Fa length . -The size of compressed name is returned or \-1 if there was an error. -.Pp -The variables -.Ft statp->res_h_errno -/ -.Ft _res.res_h_errno -and external variable -.Ft h_errno -is set whenever an error occurs during resolver operation.

Up to -.Dv MAXNS -(see -.Pa <resolv.h> ) -name servers may be listed, one per keyword. -If there are multiple servers, the -.Nm resolver -library queries them in the order listed. -If no -.Li nameserver -entries are present, the default is to use the name server on the local machine. -(The algorithm used is to try a name server, and if the query times out, -try the next, until out of name servers, -then repeat trying all the name servers -until a maximum number of retries are made). -.It Li domain -Local domain name. -Most queries for names within this domain can use short names -relative to the local domain. -If no -.Li domain -entry is present, the domain is determined from the local host name returned by -.Xr gethostname @BSD_SYSCALL_EXT@ ; -the domain part is taken to be everything after the first -.Sq \&. . -Finally, if the host name does not contain a domain part, the root -domain is assumed. -.It Li search -Search list for host-name lookup. -The search list is normally determined from the local domain name; -by default, it contains only the local domain name. -This may be changed by listing the desired domain search path -following the -.Li search -keyword with spaces or tabs separating the names. -Most -.Nm resolver -queries will be attempted using each component -of the search path in turn until a match is found. -Note that this process may be slow and will generate a lot of network -traffic if the servers for the listed domains are not local, -and that queries will time out if no server is available -for one of the domains. -.Pp -The search list is currently limited to six domains -with a total of 256 characters. -.It Li sortlist -Allows addresses returned by gethostbyname to be sorted. -A -.Li sortlist -is specified by IP address netmask pairs.

Also, -the external interface isn't changed (other than being extended), i.e., -a BIND server that allows dynamic updates and/or T_UNSPEC data can -still talk to a 'vanilla' server using the 'vanilla' operations. - -The description that follows is broken into 3 parts: a functional -description of the dynamic update facility, a functional description of -the T_UNSPEC facility, and a discussion of the implementation of -dynamic updates. The implementation description is mostly intended for -those who want to make future enhancements (especially the addition of -a good authentication mechanism). If you make enhancements, I would be -interested in hearing about them. - - - - - - 1. Dynamic Update Facility - -I added this code in conjunction with my research into naming in large -heterogeneous systems. For the purposes of this research, I ignored -security issues. In other words, no authentication/authorization -mechanism exists to control updates. Authentication will hopefully be -addressed at some future point (although probably not by me). In the -mean time, BIND Internet name servers (as opposed to "private" name -server networks operating with their own port numbers, as I use in my -research) should be compiled *without* -DALLOW_UPDATES, so that the -integrity of the Internet name database won't be compromised by this -code. - - -There are 5 different dynamic update interfaces: - UPDATEA - add a resource record - UPDATED - delete a specific resource record - UPDATEDA - delete all named resource records - UPDATEM - modify a specific resource record - UPDATEMA - modify all named resource records - -These all work through the normal resolver interface, i.e., these -interfaces are opcodes, and the data in the buffers passed to -res_mkquery must conform to what is expected for the particular -operation (see the #ifdef ALLOW_UPDATES extensions to nstest.c for -example usage). - -UPDATEM is logically equivalent to an UPDATED followed by an UPDATEA, -except that the updates occur atomically at the primary server (as -usual with Domain servers, secondaries may become temporarily -inconsistent). The difference between UPDATED and UPDATEDA is that the -latter allows you to delete all RRs associated with a name; similarly -for UPDATEM and UPDATEMA. The reason for the UPDATE{D,M}A interfaces -is two-fold: - - 1. Sometimes you want to delete/modify some data, but you know you'll - only have a single RR for that data; in such a case, it's more - convenient to delete/modify the RR by just giving the name; - otherwise, you would have to first look it up, and then - delete/modify it. - - 2. It is sometimes useful to be able to delete/modify multiple RRs - this way, since one can then perform the operation atomically. - Otherwise, one would have to delete/modify the RRs one-by-one. - -One additional point to note about UPDATEMA is that it will return a -success status if there were *zero* or more RRs associated with the given -name (and the RR add succeeds), whereas UPDATEM, UPDATED, and UPDATEDA -will return a success status if there were *one* or more RRs associated -with the given name. The reason for the difference is to handle the -(probably common) case where what you want to do is set a particular -name to contain a single RR, irrespective of whether or not it was -already set. - - - - - 2. T_UNSPEC Facility - -Type T_UNSPEC allows you to store data whose layout BIND doesn't -understand. Data of this type is not marshalled (i.e., converted -between host and network representation, as is done, for example, with -Internet addresses) by BIND, so it is up to the client to make sure -things work out ok w.r.t. heterogeneous data representations. The way -I use this type is to have the client marshal data, store it, retrieve -it, and demarshal it. This way I can store arbitrary data in BIND -without having to add new code for each specific type. - -T_UNSPEC data is dumped in an ASCII-encoded, checksummed format so -that, although it's not human-readable, it at least doesn't fill the -dump file with unprintable characters. - -Type T_UNSPEC is important for my research environment, where -potentially lots of people want to store data in the name service, and -each person's data looks different. Instead of having BIND understand -the format of each of their data types, the clients define marshaling -routines and pass buffers of marshalled data to BIND; BIND never tries -to demarshal the data...it just holds on to it, and gives it back to -the client when the client requests it, and the client must then -demarshal it. - -The Xerox Network System's name service (the Clearinghouse) works this -way. The reason 'vanilla' BIND understands the format of all the data -it holds is probably that BIND is tailored for a very specific -application, and wants to make sure the data it holds makes sense (and, -for some types, BIND needs to take additional action depending on the -data's semantics). For more general purpose name services (like the -Clearinghouse and my usage of BIND), this approach is less tractable. - -See the #ifdef ALLOW_T_UNSPEC extensions to nstest.c for example usage of -this type. - - - - - - - 3. Dynamic Update Implementation Description - -This section is divided into 3 subsections: General Discussion, -Miscellaneous Points, and Known Defects. - - - - - 3.1 General Discussion - -The basic scheme is this: When an update message arrives, a call is -made to InitDynUpdate, which first looks up the SOA record for the zone -the update affects. If this is the primary server for that zone, we do -the update and then update the zone serial number (so that secondaries -will refresh later). If this is a secondary server, we forward the -update to the primary, and if that's successful, we update our copy -afterwards. If it's neither, we refuse the update. (One might think -to try to propagate the update to an authoritative server; I figured -that updates will probably be most likely within an administrative -domain anyway; this could be changed if someone has strong feelings -about it). - -Note that this mechanism disallows updates when the primary is -down, preserving the Domain scheme's consistency requirements, -but making the primary a critical point for updates. This seemed -reasonable to me because - 1. Alternative schemes must deal with potentially complex - situations involving merging of inconsistent secondary - updates - 2. Updates are presumed to be rare relative to read accesses, - so this increased restrictiveness for updates over reads is - probably not critical - -I have placed comments through out the code, so it shouldn't be -too hard to see what I did. The majority of the processing is in -doupdate() and InitDynUpdate(). Also, I added a field to the zone -struct, to keep track of when zones get updated, so that only changed -zones get checkpointed. - - - - - - 3.2 Miscellaneous Points - -I use ns_maint to call zonedump() if the database changes, to -provide a checkpointing mechanism. I use the zone refresh times to -set up ns_maint interrupts if there are either secondaries or -primaries. Hence, if there is a secondary, this interrupt can cause -zoneref (as before), and if there is a primary, this interrupt can -cause doadump. I also checkpoint if needed before shutting down. - -You can force a server to checkpoint any changed zones by sending the -maint signal (SIGALRM) to the process. Otherwise it just checkpoints -during maint. interrupts, or when being shutdown (with SIGTERM). -Sending it the dump signal causes the database to be dumped into the -(single) dump file, but doesn't checkpoint (i.e., update the boot -files). Note that the boot files will be overwritten with checkpoint -files, so if you want to preserve the comments, you should keep copies -of the original boot files separate from the versions that are actually -used. - -I disallow T_SOA updates, for several reasons: - - T_SOA deletes at the primary wont be discovered by the secondaries - until they try to request them at maint time, which will cause - a failure - - the corresponding NS record would have to be deleted at the same - time (atomically) to avoid various problems - - T_SOA updates would have to be done in the right order, or else - the primary and secondaries will be out-of-sync for that zone. -My feeling is that changing the zone topology is a weighty enough thing -to do that it should involve changing the load file and reloading all -affected servers. - -There are alot of places where bind exits due to catastrophic failures -(mainly malloc failures). I don't try to dump the database in these -places because it's probably inconsistent anyway. It's probably better -to depend on the most recent dump. - - - - - - 3.2 Known Defects - -1. I put the following comment in nlookup (db_lookup.c): - - Note: at this point, if np->n_data is NULL, we could be in one - of two situations: Either we have come across a name for which - all the RRs have been (dynamically) deleted, or else we have - come across a name which has no RRs associated with it because - it is just a place holder (e.g., EDU). In the former case, we - would like to delete the namebuf, since it is no longer of use, - but in the latter case we need to hold on to it, so future - lookups that depend on it don't fail. The only way I can see - of doing this is to always leave the namebufs around (although - then the memory usage continues to grow whenever names are - added, and can never shrink back down completely when all their - associated RRs are deleted). - - Thus, there is a problem that the memory usage will keep growing for - the situation described. You might just choose to ignore this - problem (since I don't see any good way out), since things probably - wont grow fast anyway (how many names are created and then deleted - during a single server incarnation, after all?) - - The problem is that one can't delete old namebufs because one would - want to do it from db_update, but db_update calls nlookup to do the - actual work, and can't do it there, since we need to maintain place - holders. One could make db_update not call nlookup, so we know it's - ok to delete the namebuf (since we know the call is part of a delete - call); but then there is code with alot of overlapping functionality - in the 2 routines. - - This also causes another problem: If you create a name and then do - UPDATEDA, all it's RRs get deleted, but the name remains; then, if you - do a lookup on that name later, the name is found in the hash table, - but no RRs are found for it. It then forwards the query to itself (for - some reason), and then somehow decides there is no such domain, and then - returns (with the correct answer, but after going through extra work). - But the name remains, and each time it is looked up, we go through - these same steps. This should be fixed, but I don't have time right - now (and the right answer seems to come back anyway, so it's good - enough for now). - -2. There are 2 problems that crop up when you store data (other than - T_SOA and T_NS records) in the root: - a. Can't get primary to doaxfr RRs other than SOA and NS to - secondary. - b. Upon checkpoint (zonedump), this data sometimes comes out after other - data in the root, so that (since the SOA and NS records have null - names), they will get interpreted as being records under the - other names upon the next boot up. For example, if you have a - T_A record called ABC, the checkpoint may look like: - $ORIGIN . - ABC IN A 128.95.1.3 - 99999999 IN NS UW-BORNEO. - IN SOA UW-BORNEO. SCHWARTZ.CS.WASHINGTON.EDU. - ( 50 3600 300 3600000 3600 ) - Then when booting up the next time, the SOA and NS records get - interpreted as being called "ABC" rather than the null root - name. - -3. The secondary server caches the T_A RR for the primary, and hence when - it tries to ns_forw an update, it won't find the address of the primary - using nslookup unless that T_A RR is *also* stored in the main hashtable - (by putting it in a named.db file as well as the named.ca file). - diff --git a/contrib/bind/doc/misc/FAQ.1of2 b/contrib/bind/doc/misc/FAQ.1of2 deleted file mode 100644 index 99619eb37a25..000000000000 --- a/contrib/bind/doc/misc/FAQ.1of2 +++ /dev/null @@ -1,1602 +0,0 @@ -Newsgroups: comp.protocols.tcp-ip.domains,comp.answers,news.answers -Path: vixie!news1.digital.com!su-news-hub1.bbnplanet.com!cpk-news-hub1.bbnplanet.com!news.bbnplanet.com!cam-news-hub1.bbnplanet.com!news.mathworks.com!news.kei.com!uhog.mit.edu!rutgers!njitgw.njit.edu!hertz.njit.edu!cdp2582 -From: cdp2582@hertz.njit.edu (Chris Peckham) -Subject: comp.protocols.tcp-ip.domains Frequently Asked Questions (FAQ) (Part 1 of 2) -Message-ID: <cptd-faq-1-849940949@njit.edu> -Followup-To: comp.protocols.tcp-ip.domains -Originator: cdp2582@hertz.njit.edu -Keywords: BIND,DOMAIN,DNS -Sender: news@njit.edu -Supersedes: <cptd-faq-1-847336183@njit.edu> -Nntp-Posting-Host: hertz.njit.edu -X-Posting-Frequency: posted during the first week of each month -Reply-To: domain-faq@njit.edu (comp.protocols.tcp-ip.domains FAQ comments) -Organization: NJIT.EDU - New Jersey Institute of Technology, Newark, NJ, USA -Date: Sat, 7 Dec 1996 06:42:36 GMT -Approved: news-answers-request@MIT.EDU -Expires: Sat 11 Jan 97 02:42:29 EDT -Lines: 1582 -Xref: vixie comp.protocols.tcp-ip.domains:12904 comp.answers:22440 news.answers:85682 - -Posted-By: auto-faq 3.1.1.2 -Archive-name: internet/tcp-ip/domains-faq/part1 -Revision: 1.14 1996/12/07 06:42:05 - - -Note that this posting has been split into two parts because of its size. - -$Id: FAQ.1of2,v 8.4 1996/12/18 04:22:33 vixie Exp $ - -A new version of this document appears monthly.

What is BIND ? - -Date: Tue Sep 10 23:15:58 EDT 1996 - -From the BOG Introduction - - -The Berkeley Internet Name Domain (BIND) implements an Internet name -server for the BSD operating system. The BIND consists of a server (or -``daemon'') and a resolver library. A name server is a network -service that enables clients to name resources or objects and share this -information with other objects in the network. This in effect is a -distributed data base system for objects in a computer network. BIND -is fully integrated into BSD (4.3 and later releases) network programs -for use in storing and retrieving host names and address. The system -administrator can configure the system to use BIND as a replacement to -the older host table lookup of information in the network hosts file -/etc/hosts. The default configuration for BSD uses BIND. - ------------------------------------------------------------------------------ - -Question 2.4. What is the difference between BIND and DNS ? - -Date: Tue Sep 10 23:15:58 EDT 1996 - -(text provided by Andras Salamon) DNS is the Domain Name System, a set of -protocols for a distributed database that was originally designed to -replace /etc/hosts files. DNS is most commonly used by applications to -translate domain names of hosts to IP addresses. A client of the DNS is -called a resolver; resolvers are typically located in the application -layer of the networking software of each TCP/IP capable machine. Users -typically do not interact directly with the resolver. Resolvers query the -DNS by directing queries at name servers that contain parts of the -distributed database that is accessed by using the DNS protocols. In -common usage, `the DNS' usually refers just to the data in the database. - -BIND (Berkeley Internet Name Domain) is an implementation of DNS, both -server and client. Development of BIND is funded by the Internet Software -Consortium and is coordinated by Paul Vixie. BIND has been ported to -Windows NT and VMS, but is most often found on Unix. BIND source code is -freely available and very complex; most of the development on the DNS -protocols is based on this code; and most Unix vendors ship BIND-derived -DNS implementations. As a result, the BIND name server is the most widely -used name server on the Internet. In common usage, `BIND' usually refers -to the name server that is part of the BIND distribution, and sometimes to -name servers in general (whether BIND-derived or not). - ------------------------------------------------------------------------------ - -Question 2.5. Where is the latest version of BIND located ? - -Fri Dec 6 00:23:19 EST 1996 - -This information may be found at http://www.vix.com/isc/bind.html - -At this time, BIND version of 4.9.5 may be found for anonymous ftp from - -ftp.vix.com : /pub/bind/release/4.9.5/bind-4.9.5-REL.tar.gz - -Other sites that officially mirror the BIND distribution are - -* bind.fit.qut.edu.au : /pub/bind -* ftp.funet.fi : /pub/unix/tcpip/dns/bind -* ftp.univ-lyon1.fr : /pub/mirrors/unix/bind -* ftp.oleane.net : /pub/mirrors/unix/bind -* ftp.ucr.ac.cr : /pub/Unix/dns/bind -* ftp.luth.se : /pub/unix/dns/bind/beta - -You may need GNU zip, Larry Wall's patch program (if there are any patch -files), and a C compiler to get BIND running from the above mentioned -source. - -GNU zip is available for anonymous ftp from - -prep.ai.mit.edu : /pub/gnu/gzip-1.2.4.tar - -patch is available for anonymous ftp from - -prep.ai.mit.edu : /pub/gnu/patch-2.1.tar.gz - -A version of BIND for Windows NT is available for anonymous ftp from - -ftp.vix.com : /pub/bind/release/4.9.5/contrib/ntdns495relbin.zip - -and - -ftp.vix.com : /pub/bind/release/4.9.5/contrib/ntbind495rel.zip - ------------------------------------------------------------------------------ - -Question 2.6. How can I find the path taken between two systems/domains ? - -Date: Fri Dec 6 00:10:31 EST 1996 - -On a Unix system, use traceroute. If it is not available to you, you may -obtain the source source for 'traceroute', compile it and install it on -your system. - -One version of this program with additional functionality may be found for -anonymous ftp from - -ftp.nikhef.nl : /pub/network/traceroute.tar.Z - -Another version may be found for anonymous ftp from - -ftp.psc.edu : /pub/net_tools/traceroute.tar - ------------------------------------------------------------------------------ - -Question 2.7. How do you find the hostname given the TCP-IP address ? - -Date: Thu Dec 1 09:55:24 EST 1994 - -For an address a.b.c.d you can always do: - - % nslookup - > set q=ptr - > d.c.b.a.in-addr.arpa. - -Most newer version of nslookup (since 4.8.3) will recognize an address, so -you can just say: - - % nslookup a.b.c.d - -DiG will work like this also: - - % dig -x a.b.c.d - -host from the contrib/host from the bind distribution may also be used. - ------------------------------------------------------------------------------ - -Question 2.8. How do I register a domain ? - -Date: Wed Sep 4 23:59:42 EDT 1996 - -You can talk to your Internet Service Provider (ISP). They can submit the -registration for you. If you are not going to be directly connected, they -should be able to offer MX records for your domain for mail delivery (so -that mail sent to the new domain will be sent to your "standard" account). -In the case where the registration is done by the organization itself, it -still makes the whole process much easier if the ISP is approached for -secondary servers _before_ the InterNIC is approached for registration. - -For information about making the registration yourself, look to the -InterNIC (or other similar organization). - -* anonymout ftp from internic.net : /templates -* gopher://rs.internic.net/ -* http://rs.internic.net/reg/reg-forms.html -* http://www.ripe.net/ - -You will need at least two domain name servers when you register your -domain. Many ISP's are willing to provide primary and/or secondary name -service for their customers. - -Please note that the InterNIC is now charging a fee for domain names in -the "COM", "ORG", and "NET". More information may be found from the -Internic at - -http://rs.internic.net/domain-info/fee-policy.html - -Many times, registration of a domain name can be initiated by sending -e-mail to the zone contact. You can obtain the contact in the SOA record -for the country, or in a whois server: - - $ nslookup -type=SOA fr. - origin = ns1.nic.fr - mail addr = nic.nic.fr - ... - -The mail address to contact in this case is 'nic@nic.fr' (you must -substitute an '@' for the first dot in the mail addr field). - -An alternate method to obtain the e-mail address of the national NIC is -the 'whois' server at InterNIC. - -You may be requested to make your request to another email address or -using a certain information template/application. - ------------------------------------------------------------------------------ - -Question 2.9. How can I change the IP address of our server ? - -Date: Sun May 5 22:46:28 EDT 1996 - -(From Mark Andrews) Before the move. - -* Ensure you are running a modern nameserver. BIND 4.9.3-REL + Patch1 is a - good choice. -* Inform all your secondaries that you are going to change. Have them - install both the current and new addresses in their named.boot's. -* Drop the ttl of the A's associated with the nameserver to something - small (5 min is usually good). -* Drop the refesh and retry times of the zone containing the forward - records for the server. -* Configure the new reverse zone before the move and make sure it is - operational. -* On the day of the move add the new A record(s) for the server. Don't - forget to have these added to parent domains. You will look like you are - multihomed with one interface dead. - -Move the machine after gracefully terminating any other services it is -offering. Then, - -* Fixup the A's, ttl, refresh and retry counters. (If you are running an - all server EDIT out all references to the old addresses in the cache - files). -* Inform all the secondaries the move is complete. -* Inform the parents of all zones you are primary of the new NS/A pairs - for the relevent zones. -* Inform all the administators of zones you are secondaring that the - machine has moved. -* For good measure update the serial no for all zones you are primary for. - This will flush out old A's. - ------------------------------------------------------------------------------ - -Question 2.10. Issues when changing your domain name - -Date: Sun Nov 27 23:32:41 EST 1994 - -If you are changing your domain name from abc.foobar.com to foobar.net, -the forward zones are easy and there are a number of ways to do it. One -way is the following: - -Have a single db file for the 2 domains, and have a single machine be the -primary server for both abc.foobar.com and foobar.net. - -To resolve the host foo in both domains, use a single zone file which -merely uses this for the host: - -foo IN A 1.2.3.4 - -Use a "@" wherever the domain would be used ie for the SOA: - -@ IN SOA (... - -Then use this pair of lines in your named.boot: - -primary abc.foobar.com db.foobar -primary foobar.net db.foobar - -The reverse zones should either contain PTRs to both names, or to -whichever name you believe to be canonical currently. - ------------------------------------------------------------------------------ - -Question 2.11. How memory and CPU does DNS use ? - -Date: Fri Dec 6 01:07:56 EST 1996 - -It can use quite a bit ! The main thing that BIND needs is memory. It -uses very little CPU or network bandwidth. The main considerations to -keep in mind when planning are: - -* How many zones do you have and how large are they ? -* How many clients do you expect to serve and how active are they ? - -As an example, here is a snapshot of memory usage from CSIRO Division of -Mathematics and Statistics, Australia - - Named takes several days to stabalize its memory usage. - - Our main server stabalises at ~10Mb. It takes about 3 days to - reach this size from 6 M at startup. This is under Sun OS 4.1.3U1. - -As another example, here is the configuration of ns.uu.net (from late -1994): - - ns.uu.net only does nameservice. It is running a version of BIND - 4.9.3 on a Sun Classic with 96 MB of RAM, 220 MB of swap (remember - that Sun OS will reserve swap for each fork, even if it is not needed) - running Sun OS 4.1.3_U1. - - Joseph Malcolm, of Alternet, states that named generally hovers at - 5-10% of the CPU, except after a reload, when it eats it all. - ------------------------------------------------------------------------------ - -Question 2.12. Other things to consider when planning your servers - -Date: Mon Jan 2 14:24:51 EST 1995 - -When making the plans to set up your servers, you may want to also -consider the following issues: - - A) Server O/S limitations/capacities (which tend to be widely - divergent from vendor to vendor) - B) Client resolver behavior (even more widely divergent) - C) Expected query response time - D) Redundancy - E) Desired speed of change propagation - F) Network bandwidth availability - G) Number of zones/subdomain-levels desired - H) Richness of data stored (redundant MX records? HINFO records?) - I) Ease of administration desired - J) Network topology (impacts reverse-zone volume) - - Assuming a best-possible case for the factors above, particularly (A), (B), - (C), (F), (G) & (H), it would be possible to run a 1000-node domain - using a single lowly 25 or 40 MHz 386 PC with a fairly modest amount of RAM - by today's standards, e.g. 4 or 8 Meg. However, this configuration would - be slow, unreliable, and would provide no functionality beyond your basic - address-to-name and name-to-address mappings. - - Beyond that baseline case, depending on what factors listed above, - you may want look at other strategies, such splitting up the DNS - traffic among several machines strategically located, possibly larger ones, - and/or subdividing your domain itself. There are many options, tradeoffs, - and DNS architectural paradigms from which to choose. ------------------------------------------------------------------------------ - -Question 2.13. Proper way to get NS and reverse IP records into DNS - -Date: Mon Jan 2 13:03:53 EST 1995 - -Reverse domain registration is separate from forward domain registration. -Blocks of network addresses have been delegated by the InterNIC. Check if -your network a.b.c.0 is in such a block by using nslookup: - - nslookup -type=soa c.b.a.in-addr.arpa. - nslookup -type=soa b.a.in-addr.arpa. - nslookup -type=soa a.in-addr.arpa. - -One of the above should give you the information you are looking for (the -others will return with an error something like `*** No start of authority -(SOA) records available for ...') This will give you the email address of -the person to whom you should address your change request. - -If none of these works, your network probably has not been delegated by -the InterNIC and you need to contact them directly. - -CIDR has meant that the registration is delegated, but registration of -in-addr.arpa has always been separate from forward zones - and for good -reason - in that the forward and reverse zones may have different -policies, contents etc, may be served by a different set of nameservers, -and exist at different times (usually only at point of creation). There -isn't a one-to-one mapping between the two, so merging the registration -would probably cause more problems than people forgetting/not-knowing that -they had to register in-addr.arpa zones separately. For example, there -are organizations that have hundreds of networks and two or more domains, -with a sprinkling of machines from each network in each of the domains. - ------------------------------------------------------------------------------ - -Question 2.14. How do I get my address assigned from the NIC ? - -Date: Fri Dec 6 01:11:34 EST 1996 - -You should probably ask your Internet provider to give you an address. -These days, addresses are being distributed through the providers, so that -they can assign adjacent blocks of addresses to sites that go through the -same provider, to permit more efficient routing on the backbones. - -Unless you have thousands of hosts, you probably won't be able to get a -class B these days. Instead, you can get a series of class C networks. -Large requests will be queried, so be ready to provide a network plan if -you ask for more than 16 class C networks. - -If you can't do this through your Internet provider, you can look for a -subnet registration form on rs.internic.net. See the answer in this FAQ -to the question "How do I register a domain" for a URL to these forms. - ------------------------------------------------------------------------------ - -Question 2.15. Is there a block of private IP addresses I can use? - -Date: Sun May 5 23:02:49 EDT 1996 - -Yes there is. Please refer to RFC 1918: - - 1918 Address Allocation for Private Internets. Y. Rekhter, B. - Moskowitz, D. Karrenberg, G. de Groot, & E. Lear. February 1996. - (Format: TXT=22270 bytes) - -RFC 1918 documents the allocation of the following addresses for use by -``private internets'': - - 10.0.0.0 - 10.255.255.255 - 172.16.0.0 - 172.31.255.255 - 192.168.0.0 - 192.168.255.255 - ------------------------------------------------------------------------------ - -Question 2.16. Does BIND cache negative answers (failed DNS lookups) ? - -Date: Mon Jan 2 13:55:50 EST 1995 - -Yes, BIND 4.9.3 and more recent versions will cache negative answers. - ------------------------------------------------------------------------------ - -Question 2.17. What does an NS record really do ? - -Date: Wed Sep 4 22:52:18 EDT 1996 - -The NS records in your zone data file pointing to the zone's name servers -(as opposed to the servers of delegated subdomains) don't do much. -They're essentially unused, though they are returned in the authority -section of reply packets from your name servers. - -However, the NS records in the zone file of the parent domain are used to -find the right servers to query for the zone in question. These records -are more important than the records in the zone itself. - ------------------------------------------------------------------------------ - -Question 2.18. DNS ports - -Date: Fri Feb 10 15:40:10 EST 1995 - -The following table shows what TCP/UDP ports DNS uses to send and receive -queries: - - Prot Src Dst Use - udp 53 53 Queries between servers (eg, recursive queries) - Replies to above - tcp 53 53 Queries with long replies between servers, zone - transfers Replies to above - udp >1023 53 Client queries (sendmail, nslookup, etc ...) - udp 53 >1023 Replies to above - tcp >1023 53 Client queries with long replies - tcp 53 >1023 Replies to above - - Note: >1023 is for non-priv ports on Un*x clients. On other client - types, the limit may be more or less. - -Another point to keep in mind when designing filters for DNS is that a DNS -server uses port 53 both as the source and destination for it's queries. -So, a client queries an initial server from an unreserved port number to -UDP port 53. If the server needs to query another server to get the -required info, it sends a UDP query to that server with both source and -destination ports set to 53. The response is then sent with the same -src=53 dest=53 to the first server which then responds to the original -client from port 53 to the original source port number. - -The point of all this is that putting in filters to only allow UDP between -a high port and port 53 will not work correctly, you must also allow the -port 53 to port 53 UDP to get through. - -Also, ALL versions of BIND use TCP for queries in some cases. The -original query is tried using UDP. If the response is longer than the -allocated buffer, the resolver will retry the query using a TCP -connection. If you block access to TCP port 53 as suggested above, you -may find that some things don't work. - -Newer version of BIND allow you to configure a list of IP addresses from -which to allow zone transfers. This mechanism can be used to prevent -people from outside downloading your entire namespace. - ------------------------------------------------------------------------------ - -Question 2.19. What is the cache file - -Date: Fri Dec 6 01:15:22 EST 1996 - -From the "Name Server Operations Guide" - - 6.3. Cache Initialization - - 6.3.1. root.cache - - The name server needs to know the servers that - are the authoritative name servers for the root - domain of the network. To do this we have to prime - the name server's cache with the addresses of these - higher authorities. The location of this file is - specified in the boot file. ... - ------------------------------------------------------------------------------ - -Question 2.20. Obtaining the latest cache file - -Date: Fri Dec 6 01:15:22 EST 1996 - -If you have a version of dig running, you may obtain the information with -the command - - dig @a.root-servers.net. . ns - -A perl script to handle some possible problems when using this method -from behind a firewall and that can also be used to periodically obtain -the latest cache file was posted to comp.protocols.tcp-ip.domains during -early October, 1996. It was posted with the subject "Keeping db.cache -current". It is available at -http://www.users.pfmc.net/~cdp/cptd-faq/current_db_cache.txt. - -The latest cache file may also be obtained from the InterNIC via ftp or -gopher: - - ; This file is made available by InterNIC registration services - ; under anonymous FTP as - ; file /domain/named.root - ; on server FTP.RS.INTERNIC.NET - ; -OR- under Gopher at RS.INTERNIC.NET - ; under menu InterNIC Registration Services (NSI) - ; submenu InterNIC Registration Archives - ; file named.root - ------------------------------------------------------------------------------ - -Question 2.21. Selecting a nameserver/root cache - -Date: Mon Aug 5 22:54:11 EDT 1996 - -Exactly how is the a root server selected from the root cache? Does the -resolver attempt to pick the closest host or is it random or is it via -sortlist-type workings? If the root server selected is not available (for -whatever reason), will the the query fail instead of attempting another -root server in the list ? - -Every recursive BIND name server (that is, one which is willing to go out -and find something for you if you ask it something it doesn't know) will -remember the measured round trip time to each server it sends queries to. -If it has a choice of several servers for some domain (like "." for -example) it will use the one whose measured RTT is lowest. - -Since the measured RTT of all NS RRs starts at zero (0), every one gets -tried one time. Once all have responded, all RTT's will be nonzero, and -the "fastest server" will get all queries henceforth, until it slows down -for some reason. - -To promote dispersion and good recordkeeping, BIND will penalize the RTT -by a little bit each time a server is reused, and it will penalize the RTT -a _lot_ if it ever has to retransmit a query. For a server to stay "#1", -it has to keep on answering quickly and consistently. - -Note that this is something BIND does that the DNS Specification does not -mention at all. So other servers, those not based on BIND, might behave -very differently. - ------------------------------------------------------------------------------ - -Question 2.22. InterNIC and domain names - -Date: Sun Jun 2 11:23:49 EDT 1996 - -The current InterNIC policy on what to do if someone wants to use a domain -name that is already in use may be found at - -rs.internic.net : /policy/internic/internic-domain-4.txt - -or - -http://rs.internic.net/domain-info/internic-domain-4.html. - -The following information was submitted by Carl Oppedahl -<oppedahl@patents.com> : - -If the jealous party happens to have a trademark registration, it is quite -likely that the domain name owner will lose the domain name, even if they -aren't infringing the trademark. This presents a substantial risk of loss -of a domain name on only 30 days' notice.

Utilities to administer DNS zone files - -Date: Wed Sep 4 22:53:53 EDT 1996 - -There are a few utilities available to ease the administration of zone -files in the DNS. - -Two common ones are h2n and makezones. Both are perl scripts. h2n is -used to convert host tables into zone data files. It is available for -anonymous ftp from - -ftp.uu.net : /published/oreilly/nutshell/dnsbind/dns.tar.Z - -makezones works from a single file that looks like a forward zone file, -with some additional syntax for special cases. It is included in the -current BIND distribution. The newest version is always available for -anonymous ftp from - -ftp.cus.cam.ac.uk : /pub/software/programs/DNS/makezones - -More information may be found using the DNS Resources Directory - -http://www.dns.net/dnsrd/. - ------------------------------------------------------------------------------ - -Question 3.2. DIG - Domain Internet Groper - -Date: Thu Dec 1 11:09:11 EST 1994 - -The latest and greatest, official, accept-no-substitutes version of the -Domain Internet Groper (DiG) is the one that comes with BIND. Get the -latest kit. - ------------------------------------------------------------------------------ - -Question 3.3. DNS packet analyser - -Date: Wed Sep 4 23:43:57 EDT 1996 - -There is a free ethernet analyser called Ethload available for PC's -running DOS. The latest filename is ETHLD104.ZIP. It understands lots of -protocols including TCP/UDP. It'll look inside there and display -DNS/BOOTP/ICMP packets etc. (Ed. note: something nice for someone to add -to tcpdump ;^) ). Depending on the ethernet controller it's given it'll -perform slightly differently. It handles NDIS/Novell/Packet drivers. It -works best with Novell's promiscuous mode drivers.

It gets this information from a set of intercon- - nected servers that are spread across the world. The infor- - mation is stored in the form of "resource records" belonging - to hierarchically organized "zones". - - By default, the program simply converts between host names - and Internet addresses. However, with the -t, -a and -v - options, it can be used to find all of the information about - domain names that is maintained by the domain nameserver - system. The information printed consists of various fields - of the associated resource records that were retrieved. - - The arguments can be either host names (domain names) or - numeric Internet addresses. - -'host' is compatible with both BIND 4.9 and BIND 4.8 - -'host' may be found in contrib/host in the BIND distribution. The latest -version always available for anonymous ftp from - -ftp.nikhef.nl : /pub/network/host.tar.Z - -It may also be found for anonymous ftp from - -ftp.uu.net : /networking/ip/dns/host.tar.Z - ------------------------------------------------------------------------------ - -Question 3.5. How can I use DNS information in my program? - -Date: Fri Feb 10 15:25:11 EST 1995 - -It depends on precisely what you want to do: - -* Consider whether you need to write a program at all. It may well be - easier to write a shell program (e.g. using awk or perl) to parse the - output of dig, host or nslookup. -* If all you need is names and addresses, there will probably be system - routines 'gethostbyname' and 'gethostbyaddr' to provide this - information. -* If you need more details, then there are system routines (res_query and - res_search) to assist with making and sending DNS queries. However, - these do not include a routine to parse the resulting answer (although - routines to assist in this task are provided). There is a separate - library available that will take a DNS response and unpick it into its - constituent parts, returning a C structure that can be used by the - program. The source for this library is available for anonymous ftp at - - hpux.csc.liv.ac.uk : /hpux/Networking/Admin/resparse-1.2 - ------------------------------------------------------------------------------ - -Question 3.6. A source of information relating to DNS - -Date: Tue Nov 5 23:42:21 EST 1996 - -You may find utilities and tools to help you manage your zone files -(including WWW front-ends) in the "tools" section of the DNS resources -directory: - -http://www.dns.net/dnsrd/tools.html - -There are also a number of IP management tools available.

DEFINITIONS - - Q4.1 TCP/IP Host Naming Conventions - Q4.2 What are slaves and forwarders ? - Q4.3 When is a server authoritative? - Q4.4 My server does not consider itself authoritative ! - Q4.5 NS records don't configure servers as authoritative ? - Q4.6 underscore in host-/domainnames - Q4.7 What is lame delegation ? - Q4.8 How can I see if the server is "lame" ? - Q4.9 What does opt-class field in a zone file do? - Q4.10 Top level domains - Q4.11 Classes of networks - Q4.12 What is CIDR ? - Q4.13 What is the rule for glue ? - ------------------------------------------------------------------------------ - -Question 4.1. TCP/IP Host Naming Conventions - -Date: Mon Aug 5 22:49:46 EDT 1996 - -One guide that may be used when naming hosts is RFC 1178, "Choosing a Name -for Your Computer", which is available via anonymous FTP from - -ftp.internic.net : /rfc/rfc1178.txt - -RFCs (Request For Comments) are specifications and guidelines for how many -aspects of TCP/IP and the Internet (should) work. Most RFCs are fairly -technical documents, and some have semantics that are hotly contested in -the newsgroups. But a few, like RFC 1178, are actually good to read for -someone who's just starting along a TCP/IP path. - ------------------------------------------------------------------------------ - -Question 4.2. What are slaves and forwarders ? - -Date: Thu Dec 1 10:32:43 EST 1994 - -"forwarders" is a list of NS records that are _prepended_ to a list of NS -records to query if the data is not available locally. This allows a rich -cache of records to be built up at a centralized location. This is good -for sites that have sporadic or very slow connections to the Internet. -(demand dial-up, for example) It's also just a good idea for very large -distributed sites to increase the chance that you don't have to go off to -the Internet to get an IP address. (sometimes for addresses across the -street!) - -"slave" modifies this to say to replace the list of NS records with the -forwarders entry, instead of prepending to it. This is for firewalled -environments, where the nameserver can't directly get out to the Internet -at all. - -"slave" is meaningless (and invalid, in late-model BINDs) without -"forwarders". "forwarders" is an entry in named.boot, and therefore -applies only to the nameserver (not to resolvers). - ------------------------------------------------------------------------------ - -Question 4.3. When is a server authoritative? - -Date: Mon Jan 2 13:15:13 EST 1995 - -In the case of BIND: - -* The server contains current data in files for the zone in question (Data - must be current for secondaries, as defined in the SOA) -* The server is told that it is authoritative for the zone, by a 'primary' - or 'secondary' keyword in /etc/named.boot. -* The server does an error-free load of the zone. - ------------------------------------------------------------------------------ - -Question 4.4. My server does not consider itself authoritative ! - -Date: Mon Jan 2 13:15:13 EST 1995 - -The question was: - - What if I have set up a DNS where there is an SOA record for - the domain, but the server still does not consider itself - authoritative. (when using nslookup and set server=the correct machine.) - It seems that something is not matching up somewhere. I suspect - that this is because the service provider has not given us control - over the IP numbers in our own domain, and so while the machine listed - has an A record for an address, there is no corresponding PTR record. -With the answer: - - That's possible too, but is unrelated to the first question. - You need to be delegated a zone before outside people will start - talking to your server. However, a server can still be authoritative - for a zone even though it hasn't been delegated authority (it's just - that only the people who use that as their server will see the data). - - A server may consider itself non-authoritative even though it's a - primary if there is a syntax error in the zone (see the list in the - previous question). ------------------------------------------------------------------------------ - -Question 4.5. NS records don't configure servers as authoritative ? - -Date: Fri Dec 6 16:13:34 EST 1996 - -Nope, delegation is a separate issue from authoritativeness. You can -still be authoritative, but not delegated. (you can also be delegated, -but not authoritative -- that's a "lame delegation") - ------------------------------------------------------------------------------ - -Question 4.6. underscore in host-/domainnames - -Date: Mon Aug 5 22:39:02 EDT 1996 - -The question is "Are underscores are allowed in host- or domainnames" ? - RFC 1033 allows them. - RFC 1035 doesn't. - RFC 1123 doesn't. - dnswalk complains about them. - - -Which RFC is the final authority these days? - -Actually RFC 1035 deals with names of machines or names of mail domains. -i.e "_" is not permitted in a hostname or on the RHS of the "@" in -local@domain. - -Underscore is permitted where ever the domain is NOT one of these types -of addresses. - -In general the DNS mostly contains hostnames and mail domainnames. This -will change as new resource record types for authenticating DNS queries -start to appear. - -The latest version of 'host' checks for illegal characters in A/MX record -names and the NS/MX target names. - -After saying all of that, remember that RFC 1123 is a Required Internet -Standard (per RFC 1720), and RFC 1033 isn't. Even RFC 1035 isn't a -required standard. Therefore, RFC 1123 wins, no contest. - -From RFC 1123, Section 2.1 - - 2.1 Host Names and Numbers - - The syntax of a legal Internet host name was specified in RFC-952 - [DNS:4]. One aspect of host name syntax is hereby changed: the - restriction on the first character is relaxed to allow either a - letter or a digit. Host software MUST support this more liberal - syntax. - - And described by Dave Barr in RFC1912: - - Allowable characters in a label for a host name are only ASCII - letters, digits, and the `-' character. Labels may not be all - numbers, but may have a leading digit (e.g., 3com.com). Labels must - end and begin only with a letter or digit. See [RFC 1035] and [RFC - 1123]. (Labels were initially restricted in [RFC 1035] to start with - a letter, and some older hosts still reportedly have problems with - the relaxation in [RFC 1123].) Note there are some Internet - hostnames which violate this rule (411.org, 1776.com). - -Finally, one more piece of information (From Paul Vixie): - - RFC 1034 says only that domain names have characters in them, though it - says so with enough fancy and indirection that it's hard to tell exactly. - - Generally, for second level domains (i.e., something you would get from - InterNIC or from the US Domain Registrar and probably other ISO 3166 - country code TLDs), RFC 952 is thought to apply. RFC 952 was about host - names rather than domain names, but the rules seemed good enough. - - <domainname> ::= <hname> - - <hname> ::= <name>*["."<name>] - <name> ::= <let>[*[<let-or-digit-or-hyphen>]<let-or-digit>] - -There has been a recent update on this subject which may be found in - -ftp.internic.net : /internet-drafts/draft-andrews-dns-hostnames-03.txt. - ------------------------------------------------------------------------------ - -Question 4.7. What is lame delegation ? - -Date: Mon Aug 5 22:45:02 EDT 1996 - -Two things are required for a lame delegation: - -* A nameserver X is delegated as authoritative for a zone. -* Nameserver X is not performing nameservice for that zone. - -Try to think of a lame delegation as a long-term condition, brought about -by a misconfiguration somewhere. Bryan Beecher's 1992 LISA paper on lame -delegations is good to read on this. The problem really lies in -misconfigured nameservers, not "lameness" brought about by transient -outages. The latter is common on the Internet and hard to avoid, while -the former is correctable. - -In order to be performing nameservice for a zone, it must have (presumed -correct) data for that zone, and it must be answering authoritatively to -resolver queries for that zone. (The AA bit is set in the flags section) - -The "classic" lame delegation case is when nameserver X is delegated as -authoritative for domain Y, yet when you ask Y about X, it returns -non-authoritative data. - -Here's an example that shows what happens most often (using dig, dnswalk, -and doc to find). - -Let's say the domain bogus.com gets registered at the NIC and they have -listed 2 primary name servers, both from their *upstream* provider: - - bogus.com IN NS ns.bogus.com - bogus.com IN NS upstream.com - bogus.com IN NS upstream1.com - -So the root servers have this info. But when the admins at bogus.com -actually set up their zone files they put something like: - - bogus.com IN NS upstream.com - bogus.com IN NS upstream1.com - -So your name server may have the nameserver info cached (which it may have -gotten from the root). The root says "go ask ns.bogus.com" since they are -authoritative - -This is usually from stuff being registered at the NIC (either nic.ddn.mil -or rs.internic.net), and then updated later, but the folks who make the -updates later never let the folks at the NIC know about it. - ------------------------------------------------------------------------------ - -Question 4.8. How can I see if the server is "lame" ? - -Date: Mon Aug 5 22:45:02 EDT 1996 - -Go to the authoritative servers one level up, and ask them who they think -is authoritative, and then go ask each one of those delegees if they think -that they themselves are authoritative. If any responds "no", then you -know who the lame delegation is, and who is delegating lamely to them. -You can then send off a message to the administrators of the level above. - -The 'lamers' script from Byran Beecher really takes care of all this for -you. It parses the lame delegation notices from BIND's syslog and -summarizes them for you. It may be found in the contrib section of the -latest BIND distribution. The latest version is available for anonymous -ftp from - -terminator.cc.umich.edu : /dns/lame-delegations/ - - If you want to actively check for lame delegations, you can use 'doc' -and 'dnswalk'. You can check things manually with 'dig'. - -The InterNIC recently announced a new lame delegation that will be in -effect on 01 October, 1996. Here is a summary: - -* After receipt/processing of a name registration template, and at random - intervals thereafter, the InterNIC will perform a DNS query via UDP - Port 53 on domain names for an SOA response for the name being - registered. -* If the query of the domain name returns a non-authoritative response - from all the listed name servers, the query will be repeated four times - over the next 30 days at random intervals approximately 7 days apart, - with notification to all listed whois and nameserver contacts of the - possible pending deletion. If at least one server answers correctly, - but one or more are lame, FYI notifications will be sent to all contacts - and checking will be discontinued. Additionally, e-mail notices will be - provided to the contact for the name servers holding the delegation to - alert them to the "lame" condition. Notifications will state explicitly - the consequences of not correcting the "lame" condition and will be - assigned a descriptive subject as follows: - - Subject: Lame Delegation Notice: DOMAIN_NAME - - The notification will include a timestamp for when the query was - performed. -* If, following 30 days, the name servers still provide no SOA response, - the name will be placed in a "hold" status and the DNS information will - no longer be propagated. The administrative contact will be notified by - postal mail and all whois contacts will be notified by e-mail, with - instructions for taking corrective action. -* Following 60 days in a "hold" status, the name will be deleted and made - available for reregistration. Notification of the final deletion will - be sent to the name server and domain name contacts listed in the NIC - database. - ------------------------------------------------------------------------------ - -Question 4.9. What does opt-class field in a zone file do? - -Date: Thu Dec 1 11:10:39 EST 1994 - -This field is the address class. From the BOG - - - ...is the address class; currently, only one class - is supported: IN for internet addresses and other - internet information. Limited support is included for - the HS class, which is for MIT/Athena ``Hesiod'' - information. ------------------------------------------------------------------------------ - -Question 4.10. Top level domains - -Date: Fri Dec 6 15:13:35 EST 1996 - -A section from RFC 1591: - - 2. The Top Level Structure of the Domain Names - - In the Domain Name System (DNS) naming of computers there is a - hierarchy of names. The root of system is unnamed. There are a set - of what are called "top-level domain names" (TLDs). These are the - generic TLDs (EDU, COM, NET, ORG, GOV, MIL, and INT), and the two - letter country codes from ISO-3166. It is extremely unlikely that - any other TLDs will be created. - ------ - -[ Ed note: the ISO-3166 country codes may be found for anonymous ftp -from: - -* ftp.isi.edu : /in-notes/iana/assignments/country-codes -* ftp.ripe.net : /iso3166-codes - -] - -[ Ed note: Since the Internic started charging for registration services, -(and for other reasons) there are a number of groups that want to offer -an alternative to registering a domain under a "standard" TLD. More -information on some of these options may be found at: - -* http://www.alternic.net/ -* http://www.eu.org/ -* http://www.ml.org/mljoin.html - -You may participate in one of the discussions on iTLD proposals at - -* To sign up: http://www.newdom.com/lists -* Old postings: http://www.newdom.com/archive - -] - ------ - - ... - Under each TLD may be created a hierarchy of names. Generally, under - the generic TLDs the structure is very flat. That is, many - organizations are registered directly under the TLD, and any further - structure is up to the individual organizations. - - In the country TLDs, there is a wide variation in the structure, in - some countries the structure is very flat, in others there is - substantial structural organization. In some country domains the - second levels are generic categories (such as, AC, CO, GO, and RE), - in others they are based on political geography, and in still others, - organization names are listed directly under the country code. The - organization for the US country domain is described in RFC 1480. - - Each of the generic TLDs was created for a general category of - organizations. The country code domains (for example, FR, NL, KR, - US) are each organized by an administrator for that country. These - administrators may further delegate the management of portions of the - naming tree. These administrators are performing a public service on - behalf of the Internet community. Descriptions of the generic - domains and the US country domain follow. - - Of these generic domains, five are international in nature, and two - are restricted to use by entities in the United States. - - World Wide Generic Domains: - - COM - This domain is intended for commercial entities, that is - companies. This domain has grown very large and there is - concern about the administrative load and system performance if - the current growth pattern is continued. Consideration is - being taken to subdivide the COM domain and only allow future - commercial registrations in the subdomains. - - EDU - This domain was originally intended for all educational - institutions. Many Universities, colleges, schools, - educational service organizations, and educational consortia - have registered here. More recently a decision has been taken - to limit further registrations to 4 year colleges and - universities. Schools and 2-year colleges will be registered - in the country domains (see US Domain, especially K12 and CC, - below). - - NET - This domain is intended to hold only the computers of network - providers, that is the NIC and NOC computers, the - administrative computers, and the network node computers. The - customers of the network provider would have domain names of - their own (not in the NET TLD). - - ORG - This domain is intended as the miscellaneous TLD for - organizations that didn't fit anywhere else. Some non- - government organizations may fit here. - - INT - This domain is for organizations established by international - treaties, or international databases. - - United States Only Generic Domains: - - GOV - This domain was originally intended for any kind of government - office or agency. More recently a decision was taken to - register only agencies of the US Federal government in this - domain. State and local agencies are registered in the country - domains (see US Domain, below). - - MIL - This domain is used by the US military. - - Example country code Domain: - - US - As an example of a country domain, the US domain provides for - the registration of all kinds of entities in the United States - on the basis of political geography, that is, a hierarchy of - <entity-name>.<locality>.<state-code>.US. For example, - "IBM.Armonk.NY.US". In addition, branches of the US domain are - provided within each state for schools (K12), community - colleges (CC), technical schools (TEC), state government - agencies (STATE), councils of governments (COG),libraries - (LIB), museums (MUS), and several other generic types of - entities (see RFC 1480 for details). - - -A section from RFC 1480: - - 2. NAMING STRUCTURE - - The US Domain hierarchy is based on political geography. The - basic name space under US is the state name space, then the - "locality" name space, (like a city, or county) then - organization or computer name and so on. - - For example: - - BERKELEY.CA.US - PORTLAND.WA.US - - There is of course no problem with running out of names. - - The things that are named are individual computers. - - If you register now in one city and then move, the database can - be updated with a new name in your new city, and a pointer can - be set up from your old name to your new name. This type of - pointer is called a CNAME record. - - The use of unregistered names is not effective and causes problems - for other users. Inventing your own name and using it without - registering is not a good idea. - - In addition to strictly geographically names, some special names - are used, such as FED, STATE, AGENCY, DISTRICT, K12, LIB, CC, - CITY, and COUNTY. Several new name spaces have been created, - DNI, GEN, and TEC, and a minor change under the "locality" name - space was made to the existing CITY and COUNTY subdomains by - abbreviating them to CI and CO. A detailed description - follows. - - Below US, Parallel to States: - ----------------------------- - - "FED" - This branch may be used for agencies of the federal - government. For example: <org-name>.<city>.FED.US - - "DNI" - DISTRIBUTED NATIONAL INSTITUTES - The "DNI" branch was - created directly under the top-level US. This branch is to be used - for distributed national institutes; organizations that span state, - regional, and other organizational boundaries; that are national in - scope, and have distributed facilities. For example: - <org-name>.DNI.US. - - Name Space Within States: - ------------------------ - - "locality" - cities, counties, parishes, and townships. Subdomains - under the "locality" would be like CI.<city>.<state>.US, - CO.<county>.<state>.US, or businesses. For example: - Petville.Marvista.CA.US. - - "CI" - This branch is used for city government agencies and is a - subdomain under the "locality" name (like Los Angeles). For example: - Fire-Dept.CI.Los-Angeles.CA.US. - - "CO" - This branch is used for county government agencies and is a - subdomain under the "locality" name (like Los Angeles). For example: - Fire-Dept.CO.San-Diego.CA.US. - - "K12" - This branch may be used for public school districts. A - special name "PVT" can be used in the place of a school district name - for private schools. For example: <school-name>.K12.<state>.US and - <school-name>.PVT.K12.<state>.US. - - "CC" - COMMUNITY COLLEGES - This branch was established for all state - wide community colleges. For example: <school-name>.CC.<state>.US. - - "TEC" - TECHNICAL AND VOCATIONAL SCHOOLS - The branch "TEC" was - established for technical and vocational schools and colleges. For - example: <school-name>.TEC.<state>.US. - - "LIB" - LIBRARIES (STATE, REGIONAL, CITY, COUNTY) - This branch may - be used for libraries only. For example: <lib-name>.LIB.<state>.US. - - "STATE" - This branch may be used for state government agencies. For - example: <org-name>.STATE.<state>.US. - - "GEN" - GENERAL INDEPENDENT ENTITY - This branch is for the things - that don't fit easily into any other structure listed -- things that - might fit in to something like ORG at the top-level. It is best not - to use the same keywords (ORG, EDU, COM, etc.) that are used at the - top-level to avoid confusion. GEN would be used for such things as, - state-wide organizations, clubs, or domain parks. For example: - <org-name>.GEN.<state-code>.US. - -The application form for the US domain may be found: - -* for anonymous ftp from internic.net : /templates/us-domain-template.txt -* http://www.isi.edu/us-domain/ - -The application form for the EDU, COM, NET, ORG, and GOV domains may be -found for anonymous ftp from: - -internic.net : /templates/domain-template.txt - ------------------------------------------------------------------------------ - -Question 4.11.

What is CIDR ? - -Date: Tue Nov 5 23:47:29 EST 1996 - -CIDR is "Classless Inter-Domain Routing (CIDR). From RFC 1517: - - ...Classless Inter-Domain Routing (CIDR) attempts to deal with - these problems by defining a mechanism to slow the growth of - routing tables and reduce the need to allocate new IP network - numbers. - -Much more information may be obtained in RFCs 1467, 1517, 1518, 1520; -with primary reference 1519. - -Also please see the CIDR FAQ at - -* http://www.ibm.net.il/~hank/cidr.html -* http://www.rain.net/faqs/cidr.faq.html -* http://www.lab.unisource.ch/services/internet/direct/cidr.html - ------------------------------------------------------------------------------ - -Question 4.13. What is the rule for glue ? - -Date: Fri Apr 28 13:31:24 EDT 1995 - -A glue record is an A record for a name that appears on the right-hand -side of a NS record. So, if you have this: - - - sub.foobar.com. IN NS dns.sub.foobar.com. - dns.sub.foobar.com. IN A 1.2.3.4 - -then the second record is a glue record (for the NS record above it). - -You need glue records when -- and only when -- you are delegating -authority to a nameserver that "lives" in the domain you are delegating -*and* you aren't a secondary server for that domain. - -In other words, in the example above, you need to add an A record for -dns.sub.foobar.com since it "lives" in the domain it serves. This boot -strapping information is necessary: How are you supposed to find out the -IP address of the nameserver for domain FOO if the nameserver for FOO -"lives" in FOO? - -If you have this NS record: - - sub.foobar.com. IN NS dns.xyz123.com. - -you do NOT need a glue record, and, in fact, adding one is a very bad -idea. If you add one, and then the folks at xyz123.com change the -address, then you will be passing out incorrect data. - -Also, unless you actually have a machine called something.IN-ADDR.ARPA, -you will never have any glue records present in any of your "reverse" -files. - -There is also a sort of implicit glue record that can be useful (or -confusing :^) ). If the parent server (abc.foobar.com domain in example -above) is a secondary server for the child, then the A record will be -fetched from the child server when the zone transfer is done. The glue is -still there but it's a little different, it's in the ip address in the -named.boot line instead of explicitly in the data. In this case you can -leave out the explicit glue A record and leave the manually configured -"glue" in just the one place in the named.boot file. - -RFC 1537 says it quite nicely: - - 2. Glue records - - Quite often, people put unnecessary glue (A) records in their - zone files. Even worse is that I've even seen *wrong* glue records - for an external host in a primary zone file! Glue records need only - be in a zone file if the server host is within the zone and there - is no A record for that host elsewhere in the zone file. - - Old BIND versions ("native" 4.8.3 and older versions) showed the - problem that wrong glue records could enter secondary servers in - a zone transfer. - - -The remainder of the FAQ is in the next part (Part 2 of 2). - diff --git a/contrib/bind/doc/misc/FAQ.2of2 b/contrib/bind/doc/misc/FAQ.2of2 deleted file mode 100644 index 40e16494b5bf..000000000000 --- a/contrib/bind/doc/misc/FAQ.2of2 +++ /dev/null @@ -1,1298 +0,0 @@ -Newsgroups: comp.protocols.tcp-ip.domains,comp.answers,news.answers -Path: vixie!news1.digital.com!su-news-hub1.bbnplanet.com!news.bbnplanet.com!cam-news-hub1.bbnplanet.com!news.mathworks.com!news.kei.com!uhog.mit.edu!rutgers!njitgw.njit.edu!hertz.njit.edu!cdp2582 -From: cdp2582@hertz.njit.edu (Chris Peckham) -Subject: comp.protocols.tcp-ip.domains Frequently Asked Questions (FAQ) (Part 2 of 2) -Message-ID: <cptd-faq-2-849940949@njit.edu> -Followup-To: comp.protocols.tcp-ip.domains -Originator: cdp2582@hertz.njit.edu -Keywords: BIND,DOMAIN,DNS -Sender: news@njit.edu -Supersedes: <cptd-faq-2-847336183@njit.edu> -Nntp-Posting-Host: hertz.njit.edu -X-Posting-Frequency: posted during the first week of each month -Reply-To: domain-faq@njit.edu (comp.protocols.tcp-ip.domains FAQ comments) -Organization: NJIT.EDU - New Jersey Institute of Technology, Newark, NJ, USA -References: <cptd-faq-1-849940949@njit.edu> -Date: Sat, 7 Dec 1996 06:42:49 GMT -Approved: news-answers-request@MIT.EDU -Expires: Sat 11 Jan 97 02:42:29 EDT -Lines: 1277 -Xref: vixie comp.protocols.tcp-ip.domains:12905 comp.answers:22441 news.answers:85683 - -Posted-By: auto-faq 3.1.1.2 -Archive-name: internet/tcp-ip/domains-faq/part2 -Revision: 1.13 1996/12/07 06:42:15 - - -(Continued from Part 1, where you'll find the introduction and -table of contents.) - - -=============================================================================== - -Section 5.

Changing a Secondary server to a Primary server ? - -Date: Fri Jul 5 23:54:35 EDT 1996 - -For 4.8.3, it's prudent to kill and restart following any changes to -named.boot. - -In BIND 4.9.3, you only have to kill and restart named if you change a -primary zone to a secondary or v-v, or if you delete a zone and remain -authoritative for its parent. Every other case should be taken care of by -a HUP. (Ed. note: 4.9.3b9 may still require you to kill and restart the -server due to some bugs in the HUP code). - -You will also need to update the server information on the root servers. -You can do this by filing a new domain registration form to inform -InterNIC of the change. They will then update the root server's SOA -records. This process usually takes 10-12 business days after they -receive the request. - ------------------------------------------------------------------------------ - -Question 5.2. Moving a Primary server to another server - -Date: Fri Jul 5 23:54:35 EDT 1996 - -The usual solution is to move the primary to ns.newserver.com, and have -ns.oldserver.com be configured as a secondary server until the change to -the root servers takes place after the request has been made to the -InterNIC. - -If you are moving to a different ISP which will change your IP's, the -recommened setting for the SOA that would minimize problems for your name -servers using the old settings can be done as follows: - -Gradually lower the TTL value in your SOA (that's the last one of the five -numbers) to always be equal to the time left until you change over. -(assuming that none of your resource records have individual TTL's set, if -so, do likewise witht them.) So, the day before, lower to 43200 seconds -(12 hours). Then lower every few hours to be the time remaining until -the change-over. So, an hour before the change, you may just want to -lower it all the way to 60 seconds or so. That way no one can cache -information past the change-over. - -After the change, start gradually incrementing the TTL value, because -you'll probably be making changes to work out problems. Once everything -stabilizes, move the TTL up to whatever your normal values are. - -To minimize name servers from using the "old settings", you can do the -same thing with the "refresh" interval in the SOA (the second number of -the SOA). That will tell the secondaries to refresh every X seconds. -Lower that value as you approach the changeover date. You probably don't -want to go much below an hour or you'll start the primary thrashing as all -the secondaries perpetually refresh. - -Also see the answer to the "How can I change the IP address of our server -?" in the INTRODUCTION section. - ------------------------------------------------------------------------------ - -Question 5.3. How do I subnet a Class B Address ? - -Date: Fri Apr 28 13:34:52 EDT 1995 - -That you need to subnet at all is something of a misconception. You can -also think of a class B network as giving you 65,534 individual hosts, and -such a network will work. You can also configure your class B as 16,384 -networks of 2 hosts each. That's obviously not very practical, but it -needs to be made clear that you are not constrained by the size of an -octet (remember that many older devices would not work in a network -configured in this manner). - -So, the question is: why do you need to subnet? One reason is that it is -easier to manage a subnetted network, and in fact, you can delegate the -responsibility for address space management to local administrators on the -various subnets. Also, IP based problems will end up localized rather -than affecting your entire network. - -If your network is a large backbone with numerous segments individually -branching off the backbone, that too suggests subnetting. - -Subnetting can also be used to improve routing conditions. - -You may wish to partition your network to disallow certain protocols on -certain segments of your net. You can, for example, restrict IP or IPX to -certain segments only by adding a router routing high level protocols, -and across the router you may have to subnet. - -Finally, as far as how many subnets you need depends on the answer to the -above question. As far as subnet masks are concerned, the mask can be -anything from 255.0.0.0 to 255.255.255.252. You'll probably be looking at -9 or 10 bits for the subnet (last octet 128 or 192 respectively). RFC -1219 discusses the issue of subnetting very well and leaves the network -administrator with a large amount of flexibility for future growth. - ------------------------------------------------------------------------------ - -Question 5.4. Subnetted domain name service - -Date: Mon Aug 5 23:00:16 EDT 1996 - -If you are looking for some examples of handling subnetted class C -networks as separate DNS domains, see the Internet Draft - -draft-ietf-cidrd-classless-inaddr-02.txt - -for more information. This file is available for anonymous ftp at - -ds.internic.net : -/internet-drafts/draft-ietf-cidrd-classless-inaddr-02.txt - -or other IETF mirror sites (ftp.is.ca.za [Africa], nic.nordu.net [Europe], -munnari.oz.au [Pacific Rim], ds.internic.net [US East Coast], or -ftp.isi.edu [US West Coast]). - -Details follow- You need to delegate down to the fourth octet, so you will -have one domain per IP address ! Here is how you can subdelegate a -in-addr.arpa address for non-byte aligned subnet masks: - -Take as an example the net 192.1.1.x, and example subnet mask -255.255.255.240. - -We first define the domain for the class C net, - - $origin 1.1.192.in-addr.arpa - @ SOA (usual stuff) - @ ns some.nameserver - ns some.other.nameserver - ; delegate a subdomain - one ns one.nameserver - ns some.nameserver - ; delegate another - two ns two.nameserver - ns some.nameserver - ; CNAME pointers to subdomain one - 0 CNAME 0.one - 1 CNAME 1.one - ; through - 15 CNAME 15.one - ; CNAME pointers to subdomain two - 16 CNAME 16.two - 17 CNAME 17.two - 31 CNAME 31.two - ; CNAME as many as required. - -Now, in the delegated nameserver, one.nameserver - - $origin one.1.1.192.in-addr.arpa - @ SOA (usual stuff) - NS one.nameserver - NS some.nameserver ; secondary for us - 0 PTR onenet.one.domain - 1 PTR onehost.one.domain - ; through - 15 PTR lasthost.one.domain - -And similar for the two.1.1.192.in-addr.arpa delegated domain. - -There is additional documentation and a perl script that may be used for -this purpose available for anonymous ftp from: - -ftp.vix.com : /pub/bind/contrib/gencidrzone - ------------------------------------------------------------------------------ - -Question 5.5. Recommended format/style of DNS files - -Date: Sun Nov 27 23:32:41 EST 1994 - -This answer is quoted from an article posted by Paul Vixie: - - I've gone back and forth on the question of whether the BOG should - include a section on this topic. I know what I myself prefer, but - I'm wary of ramming my own stylistic preferences down the throat of - every BOG reader. But since you ask :-)... - - Create /var/named. If your system is too old to have a /var, either - create one or use /usr/local/adm/named instead. Put your named.boot - in it, and make /etc/named.boot a symlink to it. If your system - doesn't have symlinks, you're S-O-L (but you knew that). In - named.boot, put a "directory" directive that specifies your actual - BIND working directory: - - directory /var/named - - All relative pathnames used in "primary", "secondary", and "cache" - directives will be evaluated relative to this directory. Create two - subdirectories, /var/named/pri and /var/named/sec. Whenever you add - a "primary" directive to your named.boot, use "pri/WHATEVER" as the - path name. And then put the primary zone file into "pri/WHATEVER". - Likewise when you add "secondary" directives, use "sec/WHATEVER" and - BIND (really named-xfer) will create the files in that - subdirectory. - - (Variations: (1) make a midlevel directory "zones" and put "pri" and - "sec" into it; (2) if you tend to pick up a lot of secondaries from - a few hosts, group them together in their own subdirectories -- - something like /var/named/zones/uucp if you're a UUCP Project name - server.) - - For your forward files, name them after the zone. dec.com becomes - "/var/named/zones/pri/dec.com". For your reverse files, name them - after the network number. 0.1.16.in-addr.arpa becomes - "/var/named/zones/pri/16.1.0". - - When creating or maintaining primary zone files, try to use the same - SOA values everywhere, except for the serial number which varies per - zone. Put a $ORIGIN directive at the top of the primary zone file, - not because its needed (it's not since the default origin is the - zone named in the "primary" directive) but because it make it easier - to remember what you're working on when you have a lot of primary - zones. Put some comments up there indicating contact information - for the real owner if you're proxying. Use RCS and put the "Id" - in a ";" comment near the top of the zone file. - - The SOA and other top level information should all be listed - together. But don't put IN on every line, it defaults nicely. For - example: - -============== -@ IN SOA gw.home.vix.com. postmaster.vix.com. ( - 1994082501 ; serial - 3600 ; refresh (1 hour) - 1800 ; retry (30 mins) - 604800 ; expire (7 days) - 3600 ) ; minimum (1 hour) - - NS gw.home.vix.com. - NS ns.uu.net. - NS uucp-gw-1.pa.dec.com. - NS uucp-gw-2.pa.dec.com. - - MX 10 gw.home.vix.com. - MX 20 uucp-gw-1.pa.dec.com. - MX 20 uucp-gw-1.pa.dec.com. -============== - - I don't necessarily recommend those SOA values. Not every zone is - as volatile as the example shown. I do recommend that serial number - format; it's in date format with a 2-digit per-day revision number. - This format will last us until 2147 A.D. at which point I expect a - better solution will have been found :-). (Note that it would last - until 4294 A.D. except that there are some old BINDs out there that - use a signed quantity for representing serial number interally; I - suppose that as long as none of these are still running after 2047 - A.D., that we can use the above serial number format until 4294 - A.D., at which point a better solution will HAVE to be found.) - - You'll note that I use a tab stop for "IN" even though I never again - specify it. This leaves room for names longer than 7 bytes without - messing up the columns. You might also note that I've put the MX - priority and destination in the same tab stop; this is because both - are part of the RRdata and both are very different from MX which is - an RRtype. Some folks seem to prefer to group "MX" and the priority - together in one tab stop. While this looks neat it's very confusing - to newcomers and for them it violates the law of least - astonishment. - - If you have a multi-level zone (one which contains names that have - dots in them), you can use additional $ORIGIN statements but I - recommend against it since there is no "back" operator. That is, - given the above example you can add: - -============= -$ORIGIN home -gw A 192.5.5.1 -============= - - The problem with this is that subsequent RR's had better be - somewhere under the "home.vix.com" name or else the $ORIGIN that - introduces them will have to use a fully qualified name. FQDN - $ORIGIN's aren't bad and I won't be mad if you use them. - Unqualified ones as shown above are real trouble. I usually stay - away from them and just put the whole name in: - -============= -gw.home A 192.5.5.1 -============= - - In your reverse zones, you're usually in some good luck because the - owner name is usually a single short token or sometimes two. - -============= -$ORIGIN 5.5.192.in-addr.arpa. -@ IN SOA ... - NS ... -1 PTR gw.home.vix.com. -========================================= -$ORIGIN 1.16.in-addr.arpa. -@ IN SOA ... - NS ... -2.0 PTR gatekeeper.dec.com. -============= - - It is usually pretty hard to keep your forward and reverse zones in - synch. You can avoid that whole problem by just using "h2n" (see - the ORA book, DNS and BIND, and its sample toolkit, included in the - BIND distribution or on ftp.uu.net (use the QUOTE SITE EXEC INDEX - command there to find this -- I never can remember where it's at). - "h2n" and many tools like it can just read your old /etc/hosts file - and churn it into DNS zone files. (May I recommend - contrib/decwrl/mkdb.pl from the BIND distribution?) However, if you - (like me) prefer to edit these things by hand, you need to follow - the simple convention of making all of your holes consistent. If - you use 192.5.5.1 and 192.5.5.3 but not (yet) 192.5.5.2, then in - your forward file you will have something like - -============= -... -gw.home A 192.5.5.1 -;avail A 192.5.5.2 -pc.home A 192.5.5.3 -============= - - and in your reverse file you will have something like - -============= -... -1 PTR gw.home.vix.com. -;2 PTR avail -3 PTR pc.home.vix.com. -============= - - This convention will allow you to keep your sanity and make fewer - errors. Any kind of automation (h2n, mkdb, or your own - perl/tcl/awk/python tools) will help you maintain a consistent - universe even if it's also a complex one. Editing by hand doesn't - have to be deadly but you MUST take care. - ------------------------------------------------------------------------------ - -Question 5.6. DNS on a system not connected to the Internet - -Date: Sun Nov 27 23:32:41 EST 1994 - -You need to create your own root domain name server until you connect to -the internet. Your roots need to delegate to mydomain.com and any -in-addr.arpa subdomains you might have, and that's about it. As soon as -you're connected, rip out the fake roots and use the real ones. - -It does not actually have to be another server pretending to be the root. -You can set up the name server so that it is primary for each domain above -you and leave them empty (i.e. you are foo.bar.com - claim to be primary -for bar.com and com) - -If you connect intermittently and want DNS to work when you are connected, -and "fail" when you are not, you can point the resolver at the name server -at the remote site and if the connection (SLIP/PPP) isn't up, the resolver -doesn't have a route to the remote server and since there's only one name -server in resolv.conf, the resolver quickly backs off the using -/etc/hosts. No problem. You could do the same with multiple name server -and a resolver that did configurable /etc/hosts fallback. - ------------------------------------------------------------------------------ - -Question 5.7. Multiple Domain configuration - -Date: Fri Dec 2 15:40:49 EST 1994 - -If you want to have multiple domain names pointing to the same -destination, such as: - - ftp ftp.biff.com connects user to -> ftp.biff.com - ftp ftp.fred.com connects user to -> ftp.biff.com - ftp ftp.bowser.com connects user to -> ftp.biff.com - -You may do this by using CNAMEs: - - ftp.bowser.com. IN CNAME ftp.biff.com. - -You can also do the same thing with multiple A records. - ------------------------------------------------------------------------------ - -Question 5.8. wildcard MX records - -Date: Sun Nov 27 23:32:41 EST 1994 - -Does BIND not understand wildcard MX records such as the following? - - *.foo.com MX 0 mail.foo.com. - -No. It just doesn't work. - -Explicit RR's at one level of specificity will, by design, "block" a -wildcard at a lesser level of specificity. I suspect that you have an RR -(an A RR, perhaps?) for "bar.foo.com" which is blocking the application of -your "*.foo.com" wildcard. The initial MX query is thus failing (NOERROR -but an answer count of 0), and the backup query finds the A RR for -"bar.foo.com" and uses it to deliver the mail directly (which is what you -DIDN'T want it to do). Adding an explicit MX RR for the host is therefore -the right way to handle this situation. - -See RFC 1034, Section 4.3.3 ("Wildcards") for more information on this -"blocking" behavior, along with an illustrative example. See also RFC 974 -for an explanation of standard mailer behavior in the face of an "empty" -response to one's MX query. - -Basically, what it boils down to is, there is no point in trying to use a -wildcard MX for a host which is otherwise listed in the DNS. - -It just doesn't work. - ------------------------------------------------------------------------------ - -Question 5.9. How do you identify a wildcard MX record ? - -Date: Thu Dec 1 11:10:39 EST 1994 - -You don't really need to "identify" a wildcard MX RR. The precedence for -u@dom is: - - exact match MX - exact match A - wildcard MX - -One way to implement this is to query for ("dom",IN,MX) and if the answer -name that comes back is "*." something, you know it's a wildcard, -therefore you know there is no exact match MX, and you therefore query for -("dom",IN,A) and if you get something, use it. if you don't, use the -previous wildcard response. - -RFC 974 explains this pretty well. - ------------------------------------------------------------------------------ - -Question 5.10. Why are fully qualified domain names recommended ? - -Date: Sun Nov 27 23:32:41 EST 1994 - -The documentation for BIND 4.9.2 says that the hostname should be set to -the full domain style name (i.e host.our.domain rather than host). What -advantages are there in this, and are there any adverse consequences if we -don't? - -Paul Vixie likes to do it :-) He lists a few reasons - - -* Sendmail can be configured to just use Dj$w rather than Dj$w.mumble - where "mumble" is something you have to edit in by hand. Granted, most - people use "mumble" elsewhere in their config files ("tack on local - domain", etc) but why should it be a requirement ? -* The real reason is that not doing it violates a very useful invariant: - gethostbyname(gethostname) == gethostbyaddr(primary_interface_address) - - If you take an address and go "backwards" through the PTR's with it, - you'll get a FQDN, and if you push that back through the A RR's, you get - the same address. Or you should. Many multi-homed hosts violate this - uncaringly. - - If you take a non-FQDN hostname and push it "forwards" through the A - RR's, you get an address which, if you push it through the PTR's, comes - back as a FQDN which is not the same as the hostname you started with. - Consider the fact that, absent NIS/YP, there is no "domainname" command - analogous to the "hostname" command. (NIS/YP's doesn't count, of - course, since it's sometimes-but-only-rarely the same as the Internet - domain or subdomain above a given host's name.) The "domain" keyword in - resolv.conf doesn't specify the parent domain of the current host; it - specifies the default domain of queries initiated on the current host, - which can be a very different thing. (As of RFC 1535 and BIND 4.9.2's - compliance with it, most people use "search" in resolv.conf, which - overrides "domain", anyway.) - - What this means is that there is NO authoritative way to - programmatically discover your host's FQDN unless it is set in the - hostname, or unless every application is willing to grovel the "netstat - -in" tables, find what it hopes is the primary address, and do a PTR - query on it. - - FQDN /bin/hostnames are, intuitively or not, the simplest way to go. - ------------------------------------------------------------------------------ - -Question 5.11. Distributing load using named - -Date: Wed Mar 1 11:04:43 EST 1995 - -When you attempt to distribute the load on a system using named, the first -response be cached, and then later queries use the cached value (This -would be for requests that come through the same server). Therefore, it -can be useful to use a lower TTL on records where this is important. You -can use values like 300 or 500 seconds. - -If your local caching server has ROUND_ROBIN, it does not matter what the -authoritative servers have -- every response from the cache is rotated. - -But if it doesn't, and the authoritative server site is depending on this -feature (or the old "shuffle-A") to do load balancing, then if one doesn't -use small TTLs, one could conceivably end up with a really nasty -situation, e.g., hundreds of workstations at a branch campus pounding on -the same front end at the authoritative server's site during class -registration. - -Not nice. - -Paul Vixie has an example of the ROUND_ROBIN code in action. Here is -something that he wrote regarding his example: - - >I want users to be distributed evenly among those 3 hosts. - - Believe it or not :-), BIND offers an ugly way to do this. I offer - for your collective amusement the following snippet from the - ugly.vix.com zone file: - - hydra cname hydra1 - cname hydra2 - cname hydra3 - hydra1 a 10.1.0.1 - a 10.1.0.2 - a 10.1.0.3 - hydra2 a 10.2.0.1 - a 10.2.0.2 - a 10.2.0.3 - hydra3 a 10.3.0.1 - a 10.3.0.2 - a 10.3.0.3 - - Note that having multiple CNAME RR's at a given name is - meaningless according to the DNS RFCs but BIND doesn't mind (in - fact it doesn't even complain). If you call - gethostbyname("hydra.ugly.vix.com") (try it!) you will get - results like the following. Note that there are two round robin - rotations going on: one at ("hydra",CNAME) and one at each - ("hydra1",A) et al. I used a layer of CNAME's above the layer of - A's to keep the response size down. If you don't have nine - addresses you probably don't care and would just use a pile of - CNAME's pointing directly at real host names. - - {hydra.ugly.vix.com - name: hydra2.ugly.vix.com - aliases: hydra.ugly.vix.com - addresses: 10.2.0.2 10.2.0.3 10.2.0.1 - - {hydra.ugly.vix.com - name: hydra3.ugly.vix.com - aliases: hydra.ugly.vix.com - addresses: 10.3.0.2 10.3.0.3 10.3.0.1 - - {hydra.ugly.vix.com - name: hydra1.ugly.vix.com - aliases: hydra.ugly.vix.com - addresses: 10.1.0.2 10.1.0.3 10.1.0.1 - - {hydra.ugly.vix.com - name: hydra2.ugly.vix.com - aliases: hydra.ugly.vix.com - addresses: 10.2.0.3 10.2.0.1 10.2.0.2 - - {hydra.ugly.vix.com - name: hydra3.ugly.vix.com - aliases: hydra.ugly.vix.com - addresses: 10.3.0.3 10.3.0.1 10.3.0.2 - ------------------------------------------------------------------------------ - -Question 5.12. Order of returned records - -Sorting, is the *resolver's* responsibility. RFC 1123: - - - 6.1.3.4 Multihomed Hosts - - When the host name-to-address function encounters a host - with multiple addresses, it SHOULD rank or sort the - addresses using knowledge of the immediately connected - network number(s) and any other applicable performance or - history information. - - DISCUSSION: - The different addresses of a multihomed host generally - imply different Internet paths, and some paths may be - preferable to others in performance, reliability, or - administrative restrictions. There is no general way - for the domain system to determine the best path. A - recommended approach is to base this decision on local - configuration information set by the system - administrator. - -In BIND 4.9.x's resolver code, the "sortlist" directive in resolv.conf -can be used to configure this. - ------------------------------------------------------------------------------ - -Question 5.13. resolv.conf - -Date: Fri Feb 10 15:46:17 EST 1995 - -The question was asked one time, "Why should I use 'real' IP addresses in -/etc/resolv.conf and not 0.0.0.0 or 127.0.0.1" ? - -Paul Vixie writes on the issue of the contents of resolv.conf: - - It's historical. Some kernels can't unbind a UDP socket's source - address, and some resolver versions (notably not including BIND - 4.9.2 or 4.9.3's) try to do this. The result can be wide area - network traffic with 127.0.0.1 as the source address. Rather than - giving out a long and detailed map of version/vendor combinations of - kernels/BINDs that have/don't this problem, I just tell folks not to - use 127.0.0.1 at all. - - 0.0.0.0 is just an alias for the first interface address assigned - after a system boot, and if that interface is a up-and-down point to - point link (PPP, SLIP, whatever), there's no guarantee that you'll - be able to reach yourself via 0.0.0.0 during the entire lifetime of - any system instance. On most kernels you can finesse this by adding - static routes to 127.0.0.1 for each of your interface addresses, but - some kernels don't like that trick and rather than give a detailed - map of which ones work and which ones don't, I just globally - recommend against 0.0.0.0. - - If you know enough to know that 127.0.0.1 or 0.0.0.0 is safe on your - kernel and resolver, then feel free to use them. If you don't know - for sure that it is safe, don't use them. I never use them (except - on my laptop, whose hostname is "localhost" and whose 0.0.0.0 is - 127.0.0.1 since I ifconfig my lo0 before any other interface). The - operational advantage to using a real IP address rather than an - wormhole like 0.0.0.0 or 127.0.0.1, is that you can then "rdist" or - otherwise share identical copies of your resolv.conf on all the - systems on any given subnet, not all of which will be servers. - -The problem was with older versions of the resolver (4.8.X). If you -listed 127.0.0.1 as the first entry in resolv.conf, and for whatever -reason the local name server wasn't running and the resolver fell back to -the second name server listed, it would send queries to the name server -with the source IP address set to 127.0.0.1 (as it was set when the -resolver was trying to send to 127.0.0.1--you use the loopback address to -send to the loopback address). - ------------------------------------------------------------------------------ - -Question 5.14. How do I delegate authority for sub-domains ? - -Date: Sat Dec 7 02:04:17 EST 1996 - -When you start having a very big domain that can be broken into logical -and separate entities that can look after their own DNS information, you -will probably want to do this. Maintain a central area for the things -that everyone needs to see and delegate the authority for the other parts -of the organization so that they can manage themselves. - -Another essential piece of information is that every domain that exists -must have it NS records associated with it. These NS records denote the -name servers that are queried for information about that zone. For your -zone to be recognized by the outside world, the server responsible for the -zone above you must have created a NS record for your your new servers -(NOTE that the new servers DO NOT have to be in the new domain). For -example, putting the computer club onto the network and giving them -control over their own part of the domain space we have the following. - -The machine authorative for gu.uwa.edu.au is mackerel and the machine -authorative for ucc.gu.uwa.edu.au is marlin. - -in mackerel's data for gu.uwa.edu.au we have the following - - @ IN SOA ... - IN A 130.95.100.3 - IN MX mackerel.gu.uwa.edu.au. - IN MX uniwa.uwa.edu.au. - - marlin IN A 130.95.100.4 - - ucc IN NS marlin.gu.uwa.edu.au. - IN NS mackerel.gu.uwa.edu.au. - -Marlin is also given an IP in our domain as a convenience. If they blow -up their name serving there is less that can go wrong because people can -still see that machine which is a start. You could place "marlin.ucc" in -the first column and leave the machine totally inside the ucc domain as -well. - -The second NS line is because mackerel will be acting as secondary name -server for the ucc.gu domain. Do not include this line if you are not -authorative for the information included in the sub-domain. - ------------------------------------------------------------------------------ - -Question 5.15.

Patches to add functionality to BIND - -Date: Tue Nov 5 23:53:47 EST 1996 - -There are others, but these are listed here: - -* When using the round robin DNS and assigning 3 IPs to a host (for - example), a process to guarantee that all 3 IPs are reachable may be - found at - http://www-leland.stanford.edu/~schemers/docs/lbnamed/lbnamed.html - -* Patches for 4.9.3-REL that will support the IPv6 AAAA record format may - be found at ftp.inria.fr : /network/ipv6/ - -* A patch for 4.9.3-REL that will allow you to turn off forwarding of - information from my server may be found at ftp.vix.com : - /pub/bind/release/4.9.3/contrib/noforward.tar.gz - -* How do I tell a server to listen to a particular interface to listen and - respond to DNS queries on ? - - Mark Andrews has a patch that will tell a 4.9.4 server to listen to a - particular interface and respond to DNS queries. It may be found at an - unofficial location: http://www.ultra.net/~jzp/andrews.patch.txt - ------------------------------------------------------------------------------ - -Question 5.17. How to serve multiple domains from one server - -Date: Tue Nov 5 23:44:02 EST 1996 - -Most name server implementations allow information about multiple domains -to be kept on one server, and questions about those domains to be -answered by that one server. For instance, there are many large servers -on the Internet that each serve information about more than 1000 -different domains. - -To be completely accurate, a server contains information about zones, -which are parts of domains that are kept as a single unit. [Ed note: for -a definition of zones and domains, see Section 2: The Name Service in the -"Name Server Operations Guide" included with the BIND 4.9.5 distribution.] - -In the configuration of the name server, the additional zones need to be -specified. An important consideration is whether a particular server is -primary or secondary for any specific zone--a secondary server maintains -only a copy of the zone, periodically refreshing its copy from another, -specified, server. In BIND, to set up a server as a secondary server for -the x.y.z zone, to the configuration file /etc/named.boot add the line - - secondary x.y.z 10.0.0.1 db.x.y.z - -where 10.0.0.1 is the IP address of the server that the zone will be -copied from, and db.x.y.z is a local filename that will contain the copy -of the zone. - -If this is a question related to how to set up multiple IP numbers on one -system, which you do not need to do to act as a domain server for -multiple domains, see - -http://www.thesphere.com/%7Edlp/TwoServers/. - -=============================================================================== - -Section 6.

Bind 4.9.x and MX querying? - -Date: Sun Nov 27 23:32:41 EST 1994 - -If you query a 4.9.x DNS server for MX records, a list of the MX records -as well as a list of the authorative nameservers is returned.

Do I need to define an A record for localhost ? - -Date: Sat Sep 9 00:36:01 EDT 1995 - -Somewhere deep in the BOG (BIND Operations Guide) that came with 4.9.3 -(section 5.4.3), it says that you define this yourself (if need be) in -the same zone files as your "real" IP addresses for your domain. Quoting -the BOG: - - - ... As implied by this PTR - record, there should be a ``localhost.my.dom.ain'' - A record (with address 127.0.0.1) in every domain - that contains hosts. ``localhost.'' will lose its - trailing dot when 1.0.0.127.in-addr.arpa is queried - for;... - -The sample files in the BIND distribution show you what needs to be done -(see the BOG). - -Some HP boxen (especially those running HP OpenView) will also need -"loopback" defined with this IP address. You may set it as a CNAME -record pointing to the "localhost." record. - ------------------------------------------------------------------------------ - -Question 6.5. MX records, CNAMES and A records for MX targets - -Date: Sun Nov 27 23:32:41 EST 1994 - -The O'Reilly "DNS and Bind" book warns against using non-canonical names -in MX records, however, this warning is given in the context of mail hubs -that MX to each other for backup purposes. How does this apply to mail -spokes. RFC 974 has a similar warning, but where is it specifically -prohibited to us an alias in an MX record ? - -Without the restrictions in the RFC, a MTA must request the A records for -every MX listed to determine if it is in the MX list then reduce the list. -This introduces many more lookups than would other wise be required. If -you are behind a 1200 bps link YOU DON'T WANT TO DO THIS. The addresses -associated with CNAMES are not passed as additional data so you will force -additional traffic to result even if you are running a caching server -locally. - -There is also the problem of how does the MTA find all of it's IP -addresses. This is not straight forward. You have to be able to do this is -you allow CNAMEs (or extra A's) as MX targets. - -The letter of the law is that an MX record should point to an A record. - -There is no "real" reason to use CNAMEs for MX targets or separate As for -nameservers any more. CNAMEs for services other than mail should be used -because there is no specified method for locating the desired server yet. - -People don't care what the names of MX targets are. They're invisible to -the process anyway. If you have mail for "mary" redirected to "sue" is -totally irrelevant. Having CNAMEs as the targets of MX's just needlessly -complicates things, and is more work for the resolver. - -Having separate A's for nameservers like "ns.your.domain" is pointless -too, since again nobody cares what the name of your nameserver is, since -that too is invisible to the process. If you move your nameserver from -"mary.your.domain" to "sue.your.domain" nobody need care except you and -your parent domain administrator (and the InterNIC). Even less so for -mail servers, since only you are affected. - -Q: Given the example - - - hello in cname realname - mailx in mx 0 hello - - Now, while reading the operating manual of bind it clearly states - that this is *not* valid. These two statements clearly contradict - each other. Is there some later rfc than 974 that overrides what is - said in there with respect to MX and CNAMEs? Anyone have the - reference handy? - -A: This isn't what the BOG says at all. See below. You can have a CNAME - that points to some other RR type; in fact, all CNAMEs have to point - to other names (Canonical ones, hence the C in CNAME). What you - can't have is an MX that points to a CNAME. MX RR's that point to - names which have only CNAME RR's will not work in many cases, and - RFC 974 intimates that it's a bad idea: - - Note that the algorithm to delete irrelevant RRs breaks if LOCAL has - a alias and the alias is listed in the MX records for REMOTE. (E.g. - REMOTE has an MX of ALIAS, where ALIAS has a CNAME of LOCAL). This - can be avoided if aliases are never used in the data section of MX - RRs. - - Here's the relevant BOG snippet: - - aliases {ttl addr-class CNAME Canonical name - ucbmonet IN CNAME monet - - The Canonical Name resource record, CNAME, speci- - fies an alias or nickname for the official, or - canonical, host name. This record should be the - only one associated with the alias name. All other - resource records should be associated with the - canonical name, not with the nickname. Any - resource records that include a domain name as - their value (e.g., NS or MX) must list the canoni- - cal name, not the nickname. - ------------------------------------------------------------------------------ - -Question 6.6. Can an NS record point to a CNAME ? - -Date: Wed Mar 1 11:14:10 EST 1995 - -Can I do this ? Is it legal ? - - - @ SOA (.........) - NS ns.host.this.domain. - NS second.host.another.domain. - ns CNAME third - third IN A xxx.xxx.xxx.xxx - -No. Only one RR type is allowed to refer, in its data field, to a CNAME, -and that's CNAME itself. So CNAMEs can refer to CNAMEs but NSs and MXs -cannot. - -BIND 4.9.3 (Beta11 and later) explicitly syslogs this case rather than -simply failing as pre-4.9 servers did. Here's a current example: - - Dec 7 00:52:18 gw named[17561]: "foobar.com IN NS" \ - points to a CNAME (foobar.foobar.com) - -Here is the reason why: - -Nameservers are not required to include CNAME records in the Additional -Info section returned after a query. It's partly an implementation -decision and partly a part of the spec. The algorithm described in RFC -1034 (pp24,25; info also in RFC 1035, section 3.3.11, p 18) says 'Put -whatever addresses are available into the additional section, using glue -RRs [if necessary]'. Since NS records are speced to contain only primary -names of hosts, not CNAMEs, then there's no reason for algorithm to -mention them. If, on the other hand, it's decided to allow CNAMEs in NS -records (and indeed in other records) then there's no reason that CNAME -records might not be included along with A records. The Additional Info -section is intended for any information that might be useful but which -isn't strictly the answer to the DNS query processed. It's an -implementation decision in as much as some servers used to follow CNAMEs -in NS references. - ------------------------------------------------------------------------------ - -Question 6.7. Nameserver forgets own A record - -Date: Fri Dec 2 16:17:31 EST 1994 - -Q: Lately, I've been having trouble with named 4.9.2 and 4.9.3. - Periodically, the nameserver will seem to "forget" its own A record, - although the other information stays intact. One theory I had was - that somehow a site that the nameserver was secondary for was - "corrupting" the A record somehow. - -A: This is invariably due to not removing ALL of the cached zones - when you moved to 4.9.X. Remove ALL cached zones and restart - your nameservers. - - You get "ignoreds" because the primaries for the relevant zones are - running old versions of BIND which pass out more glue than is - required. named-xfer trims off this extra glue. - ------------------------------------------------------------------------------ - -Question 6.8. General problems (core dumps !) - -Date: Sun Dec 4 22:21:22 EST 1994 - -Paul Vixie says: - - I'm always interested in hearing about cases where BIND dumps core. - However, I need a stack trace. Compile with -g and not -O (unless - you are using gcc and know what you are doing) and then when it - dumps core, get into dbx or gdb using the executable and the core - file and use "bt" to get a stack trace. Send it to me - <paul@vix.com> along with specific circumstances leading to or - surrounding the crash (test data, tail of the debug log, tail of the - syslog... whatever matters) and ideally you should save your core - dump for a day or so in case I have questions you can answer via - gdb/dbx. - ------------------------------------------------------------------------------ - -Question 6.9. malloc and DECstations - -Date: Mon Jan 2 14:19:22 EST 1995 - -We have replaced malloc on our DECstations with a malloc that is more -compact in memory usage, and this helped the operation of bind a lot.

Can't resolve names without a "." - -(Answer written by Mark Andrews) You are not using a RFC 1535 aware -resolver. Depending upon the age of your resolver you could try adding a -search directive to resolv.conf. - - e.g. - domain <domain> - search <domain> [<domain2> ...] - -If that doesn't work you can configure you server to serve the parent and -grandparent domains as this is the default search list. - -"domain langley.af.mil" has an implicit "search langley.af.mil af.mil mil" -in the old resolvers, and you are timing out trying to resolve the -address with one of these domains tacked on. - -When resolving internic.net the following will be tried in order. - internic.net.langley.af.mil - internic.net.af.mil - internic.net.mil - internic.net. - -RFC 1535 aware resolvers try qualified address first. - - internic.net. - internic.net.langley.af.mil - internic.net.af.mil - internic.net.mil -RFC 1535 documents the problems associated with the old search -algorithim, including security issues, and how to alleviate some of the -problems. - ------------------------------------------------------------------------------ - -Question 6.11. Err/TO errors being reported - -Date: Sun May 5 23:46:32 EDT 1996 - -Why are errors like - - Apr 2 20:41:58 nameserver named[25846]: Err/TO getting serial# for - "foobar.domain1.com" - Apr 2 20:41:59 nameserver named[25846]: Err/TO getting serial# for - "foobar.domain2.com" - -reported ? These generally indicate that there is one of the following -problems: - -* A network problem between you and the primary, -* A bad IP address in named.boot, -* The primary is Lame for the zone. - -An external check to see if you can retrieve the SOA is the best way to -work out which it is. - ------------------------------------------------------------------------------ - -Question 6.12. Why does swapping kill BIND ? - -Date: Thu Jul 4 23:20:20 EDT 1996 - -The question was: - - I've been diagnosing a problem with BIND 4.9.x (where x is usually 3BETA9 - or 3REL) for several months now. I finally tracked it down to swap space - utilization on the unix boxes. - - This happens under (at least) under Linux 1.2.9 & 1.2.13, SunOS 4.1.3U1, - 4.1.1, and Solaris 2.5. The symptom is that if these machines get into - swap at all bind quits resolving most, if not all queries. Mind you that - these machines are not "swapping hard", but rather we're talking about a - several hundred K TEMPORARY deficiency. I have noticed while digging - through various archives that there is some referral to "bind thrashing - itself to death". Is this what is happening ? - -And the answer is: - - Yes it is. Bind can't tolerate having even a few pages swapped out. - The time required to send responses climbs to several seconds/request, - and the request queue fills and overflows. - - It's possible to shrink memory consumption a lot by undefining STATS - and XSTATS, and recompiling. You could nuke DEBUG too, which will - cut the code size down some, but probably not the data size. If that - doesn't do the job then it sounds like you'll need to move DNS onto a - separate box. - - BIND tends to touch all of its resident pages all of the time with - normal activity... if you look at the RSS verses the total process - size, you will always see the RSS within, usually, 90% of the total - size of the process. This means that *any* paging of named-owned - pages will stall named. Thus, a machine running a heavily accessed - named process cannot afford to swap *at all*. - - (Paul Vixie continues on this subject): - I plan to try to get BIND to exhibit slightly better locality of - reference in some future release. Of course, I can only do this if - the query names also exhibit some kind of hot spots. If someone - queries all your names often, BIND will have to touch all of its VM - pool that often. (Right now, BIND touches everything pretty often - even if you're just hammering on some hot spots -- that's the part - I'd like to fix. Malloc isn't cooperating.) - -=============================================================================== - -Section 7.

The support is not optional, since its presence ought not to -affect anyone who does not go looking for it. The support includes: - - inet_ntop() new function. - inet_pton() new function. - RES_USE_INET6 causes gethostby*() to return either real IPv6 - addresses (if available) or mapped (::FFFF:a.b.c.d) - addresses if only IPv4 address records are found. - gethostbyname() can search for T_AAAA in preference to T_A. - gethostbyaddr() can search in IP6.INT for PTR RR's. - named can load, transfer, cache, and dump T_AAAA RRs. - - *** Some notes on the new functions *** - -The inet_pton() and inet_ntop() functions differ from the current (as of -this writing) IPv6 BSD API draft. Discussions were held, primarily between -myself and Rich Stevens, on the ipng@sunroof.eng.sun.com mailing list, and -the BIND definitions of these functions are likely to go into the next draft. -(If not, and BIND has to change its definitions of these functions, then you -will know why I chose not to document them yet!) - -These functions can return error values, and as such the process of porting -code that used inet_aton() to use inet_pton() is not just syntactic. Not all -nonzero values indicate success; consider "-1". Likewise, inet_ntoa() is not -just smaller than inet_ntop() -- it's a whole new approach. Inet_ntop() does -not return a static pointer, the caller has to supply a sized buffer. Also, -inet_ntop() can return NULL, so you should only printf() the result if you -have verified that your arguments will be seen as error free. - -The inet_pton() function is much pickier about its input format than the old -inet_aton() function has been. You can't abbreviate 10.0.0.53 as 10.53 any -more. Hexadecimal isn't accepted. You have to supply four decimal numeric -strings, each of whose value is within the range from 0 to 255. No spaces -are allowed either before, after, or within an address. If you need the older -functionality with all the shortcuts and exceptions, continue using inet_aton() -for your IPv4 address parsing needs. - - *** Some notes on RES_USE_INET6 *** - -You can set this by modifying _res.options after calling res_init(), or you -can turn it on globally by setting "options inet6" in /etc/resolv.conf. This -latter option ought to be used carefully, since _all_ applications will then -receive IPv6 style h_addr_list's from their gethostby*() calls. Once you know -that every application on your system can cope with IPv6 addressing, it is safe -and reasonable to turn on the global option. Otherwise, don't do it. - - *** Some notes on mapped IPv4 addresses *** - -There are two IPv6 prefixes set aside for IPv4 address encapsulation. See -RFC 1884 for a detailed explaination. The ::a.b.c.d form is used for -tunnelling, which means wrapping an IPv4 header around IPv6 packets and using -the existing IPv4 routing infrastructure to reach what are actually IPv6 -endpoints. The ::FFFF:a.b.c.d form can be used on dual-stack (IPv4 and IPv6) -hosts to signal a predominantly IPv6 stack that it should use ``native'' IPv4 -to reach a given destination, even though the socket's address family is -AF_INET6. - -BIND supports both of these address forms, to the extent that inet_pton() will -parse them, inet_ntop() will generate them, gethostby*() will map IPv4 into -IPv6 if the RES_USE_INET6 option is set, and gethostbyaddr() will search the -IN-ADDR.ARPA domain rather than the IP6.INT domain when it needs a PTR RR. -This last bit of behaviour is still under discussion and it's not clear that -tunnelled addresses should be mapped using IN-ADDR.ARPA. In other words, this -bit of behaviour may change in a subsequent BIND release. So now you know -another reason why none of this stuff is ``officially'' documented. diff --git a/contrib/bind/doc/misc/dns-setup b/contrib/bind/doc/misc/dns-setup deleted file mode 100644 index 19f0197f7e81..000000000000 --- a/contrib/bind/doc/misc/dns-setup +++ /dev/null @@ -1,1081 +0,0 @@ - Setting up a basic DNS server for a domain - Revision 1.1.1 - - Craig Richmond - craig@ecel.uwa.edu.au - 15th August 1993 - - -About this document - -I have written this file because it seems that the same questions seem to -pop up time and time again and when I had to install DNS from scratch the -first time, we found very little to help us. - -This document covers setting up a Domain Name Server with authority over -your domain and using a few of the more useful but less well known -(hopefully this document will take care of that) features of nslookup to -get information about the DNS and to work out why yours isn't working. - -If you are using a Sun Workstation and you want to make NIS interact with -the DNS, then this is not the FAQ for you (but it may well be when you try -to set up the DNS).

The name decel.ecel.uwa.edu.au is the number -130.95.4.2 and vice versa. This is achieved through the DNS. The DNS is a -heirarchy. There are a small number of root domain name servers that are -responsible for tracking the top level domains and who is under them. The -root domain servers between them know about all the people who have name -servers that are authoritive for domains under the root. - -Being authoritive means that if a server is asked about something in that -domain, it can say with no ambiguity whether or not a given piece of -information is true. For example. We have domains x.z and y.z. There are -by definition authoritive name servers for both of these domains and we -shall assume that the name server in both of these cases is a machine -called nic.x.z and nic.y.z but that really makes no difference. - -If someone asks nic.x.z whether there is a machine called a.x.z, then -nic.x.z can authoritively say, yes or no because it is the authoritive name -server for that domain. If someone asks nic.x.z whether there is a machine -called a.y.z then nic.x.z asks nic.y.z whether such a machine exists (and -caches this for future requests). It asks nic.y.z because nic.y.z is the -authoritive name server for the domain y.z. The information about -authoritive name servers is stored in the DNS itself and as long as you -have a pointer to a name server who is more knowledgable than yourself then -you are set. - -When a change is made, it propogates slowly out through the internet to -eventually reach all machines. The following was supplied by Mark Andrews -Mark.Andrews@syd.dms.csiro.au. - - If both the primary and all secondaries are up and talking when - a zone update occurs and for the refresh period after the - update the old data will live for max(refresh + mininum) - average (refresh/2 +mininum) for the zone.

If you have a longer -minimum, it may take a couple of days before things return to normal. - -There is also a difference between a zone and a domain. The domain is the -entire set of machines that are contained within an organisational domain -name. For example, the domain uwa.edu.au contains all the machines at the -University of Western Australia. A Zone is the area of the DNS for which a -server is responsible. The University of Western Australia is a large -organisation and trying to track all changes to machines at a central -location would be difficult. The authoritive name server for the zone -uwa.edu.au delegates the authority for the zone ecel.uwa.edu.au to -decel.ecel.uwa.edu.au.

Note that this is somewhat of a -kludge and should probably be handled far more elegantly. By placing -localhost here, a machine comes into existance called -localhost.ecel.uwa.edu.au. If you finger it, or telnet to it, you get your -own machine, because the name lookup returns 127.0.0.1 which is the special -case for your own machine. I have used a couple of different DNS packages. -The old BSD one let you put things into the cache which would always work, -but would not be exported to other nameservers. In the newer Sun one, they -are left in the cache and are mostly ignored once named is up and running. -This isn't a bad solution, its just not a good one. - -Decel is the main machine in our domain. It has the IP number 130.95.4.2 -and that is what this next line shows. It also has a HINFO entry. HINFO -is Host Info which is meant to be some sort of an indication of what the -machine is and what it runs. The values are two white space seperated -values. First being the hardware and second being the software. HINFO is -not compulsory, its just nice to have sometimes. We also have some MX -records so that mail destined for decel has some other avenues before it -bounces back to the sender if undeliverable. - -It is a good idea to give all machines capable of handling mail an MX -record because this can be cached on remote machines and will help to -reduce the load on the network. - -gopher.ecel.uwa.edu.au is the gopher server in our division. Now because -we are cheapskates and don't want to go and splurge on a seperate machine -just for handling gopher requests we have made it a CNAME to our main -machine. While it may seem pointless it does have one main advantage. -When we discover that our placing terrabytes of popular quicktime movies -on our gopher server (no we haven't and we don't intend to) causes an -unbearable load on our main machine, we can quickly move the CNAME to -point at a new machine by changing the name mentioned in the CNAME. Then -the slime of the world can continue to get their essential movies with a -minimal interuption to the network. Other good CNAMEs to maintain are -things like ftp, mailhost, netfind, archie, whois, and even dns (though the -most obvious use for this fails). It also makes it easier for people to -find these services in your domain. - -We should probably start using WKS records for things like gopher and whois -rather than making DNS names for them. The tools are not in wide -circulation for this to work though. (Plus all those comments in many DNS -implementation of "Not implemented" next to the WKS record) - -Finally we have a macintosh which belongs to my boss. All it needs is an -IP number, and we have included the HINFO so that you can see that it is in -fact a macII running a Mac System. To get the list of preferred values, -you should get a copy of RFC 1340. It lists lots of useful information -such as /etc/services values, ethernet manufacturer hardware addresses, -HINFO defualts and many others. I will include the list as it stands at -the moment, but if any RFC superceeds 1340, then it will have a more -complete list. See Appendix B for that list. - -NOTE: If Chris had a very high profile and wanted his mac to appear like a -fully connected unix machine as far as internet services were concerned, he -could simply place an MX record such as - - IN MX 100 decel - -after his machine and any mail sent to chris@chris-mac.ecel.uwa.edu.au -would be automatically rerouted to decel. - -The Reverse Mapping File - -The reverse name lookup is handled in a most bizarre fashion. Well it all -makes sense, but it is not immediately obvious. - -All of the reverse name lookups are done by finding the PTR record -associated with the name w.x.y.z.in-addr.arpa. So to find the name -associated with the IP number 1.2.3.4, we look for information stored in -the DNS under the name 4.3.2.1.in-addr.arpa. They are organised this way -so that when you are allocated a B class subnet for example, you get all of -the IP numbers in the domain 130.95. Now to turn that into a reverse name -lookup domain, you have to invert the numbers or your registered domains -will be spread all over the place. It is a mess and you need not understand -the finer points of it all. All you need to know is that you put the -reverse name lookup files back to front. - -Here is the sample reverse name lookup files to go with our example. - -0.0.127.in-addr.arpa --- -; Reverse mapping of domain names 0.0.127.in-addr.arpa -; Nobody pays attention to this, it is only so 127.0.0.1 -> localhost. -@ IN SOA decel.ecel.uwa.edu.au. postmaster.ecel.uwa.edu.au. ( - 91061801 ; Serial (yymmddxx) - 10800 ; Refresh 3 hours - 3600 ; Retry 1 hour - 3600000 ; Expire 1000 hours - 86400 ) ; Minimum 24 hours -; -1 IN PTR localhost.ecel.uwa.edu.au. --- - -4.95.130.in-addr.arpa --- -; reverse mapping of domain names 4.95.130.in-addr.arpa -; -@ IN SOA decel.ecel.uwa.edu.au. postmaster.ecel.uwa.edu.au. ( - 92050300 ; Serial (yymmddxx format) - 10800 ; Refresh 3hHours - 3600 ; Retry 1 hour - 3600000 ; Expire 1000 hours - 86400 ) ; Minimum 24 hours -2 IN PTR decel.ecel.uwa.edu.au. -3 IN PTR accfin.ecel.uwa.edu.au. -5 IN PTR chris-mac.ecel.uwa.edu.au. --- - -It is important to remember that you must have a second start of authority -record for the reverse name lookups. Each reverse name lookup file must -have its own SOA record. The reverse name lookup on the 127 domain is -debatable seeing as there is likely to be only one number in the file and -it is blatantly obvious what it is going to map to. - -The SOA details are the same as in the forward mapping. - -Each of the numbers listed down the left hand side indicates that the line -contains information for that number of the subnet. Each of the subnets -must be the more significant digits. eg the 130.95.4 of an IP number -130.95.4.2 is implicit for all numbers mentioned in the file. - -The PTR must point to a machine that can be found in the DNS. If the name -is not in the DNS, some versions of named just bomb out at this point. - -Reverse name lookups are not compulsory, but nice to have. It means that -when people log into machines, they get names indicating where they are -logged in from. It makes it easier for you to spot things that are wrong -and it is far less cryptic than having lots of numbers everywhere. Also if -you do not have a name for your machine, some brain dead protocols such as -talk will not allow you to connect. - -Since I had this I had one suggestion of an alternative way to do the -localhost entry. I think it is a matter of personal opinion so I'll -include it here in case anyone things that this is a more appropriate -method. - -The following is courtesy of jep@convex.nl (JEP de Bie) - - The way I did it was: - - 1) add in /etc/named.boot: - - primary . localhost - primary 127.in-addr.ARPA. IP127 - -(Craig: It has been suggested by Mark Andrews that this is a bad practice - particularly if you have upgraded to Bind 4.9. You also run the risk of - polluting the root name servers. This comes down to a battle of idealogy - and practicality. Think twice before declaring yourself authorative for - the root domain.) - - So I not only declare myself (falsely? - probably, but nobody is going to - listen anyway most likely [CPR]:-) athorative in the 127.in-addr.ARPA domain - but also in the . (root) domain. - - 2) the file localhost has: - - $ORIGIN . - localhost IN A 127.0.0.1 - - 3) and the file IP127: - - $ORIGIN 127.in-addr.ARPA. - 1.0.0 IN PTR localhost. - - 4) and I have in my own domain file (convex.nl) the line: - - $ORIGIN convex.nl. - localhost IN CNAME localhost. - - The advantage (elegancy?) is that a query (A) of localhost. gives the - reverse of the query of 1.0.0.127.in-addr.ARPA. And it also shows that - localhost.convex.nl is only a nickname to something more absolute. - (While the notion of localhost is of course relative :-)). - - And I also think there is a subtle difference between the lines - - primary 127.in-addr.ARPA. IP127 - and - primary 0.0.127.in-addr.ARPA. 4.95.130.domain - ============= - JEP de Bie - jep@convex.nl - ============= - - - -Delegating authority for domains within your domain: - -When you start having a very big domain that can be broken into logical and -seperate entities that can look after their own DNS information, you will -probably want to do this. Maintain a central area for the things that -everyone needs to see and delegate the authority for the other parts of the -organisation so that they can manage themselves. - -Another essential piece of information is that every domain that exists -must have it NS records associated with it. These NS records denote the -name servers that are queried for information about that zone. For your -zone to be recognised by the outside world, the server responsible for the -zone above you must have created a NS record for your machine in your -domain. For example, putting the computer club onto the network and giving -them control over their own part of the domain space we have the following. - -The machine authorative for gu.uwa.edu.au is mackerel and the machine -authorative for ucc.gu.uwa.edu.au is marlin. - -in mackerel's data for gu.uwa.edu.au we have the following - -@ IN SOA ... - IN A 130.95.100.3 - IN MX mackerel.gu.uwa.edu.au. - IN MX uniwa.uwa.edu.au. - -marlin IN A 130.95.100.4 - -ucc IN NS marlin.gu.uwa.edu.au. - IN NS mackerel.gu.uwa.edu.au. - -Marlin is also given an IP in our domain as a convenience. If they blow up -their name serving there is less that can go wrong because people can still -see that machine which is a start. You could place "marlin.ucc" in the -first column and leave the machine totally inside the ucc domain as well. - -The second NS line is because mackerel will be acting as secondary name -server for the ucc.gu domain. Do not include this line if you are not -authorative for the information included in the sub-domain. - - -Troubleshooting your named: - -Named doesn't work! What is wrong? - -Step 1: Run nslookup and see what nameserver it tries to connect you to. -If nslookup connects you to the wrong nameserver, create a /etc/resolv.conf -file that points your machine at the correct nameserver. If there is no -resolv.conf file, the the resolver uses the nameserver on the local -machine. - -Step 2: Make sure that named is actually running. - -Step 3: Restart named and see if you get any error messages on the -console and in also check /usr/adm/messages. - -Step 4: If named is running, nslookup connects to the appropriate -nameserver and nslookup can answer simple questions, but other programs -such as 'ping' do not work with names, then you need to install resolv+ -most likely. - - -I changed my named database and my local machine has noticed, but nobody -else has the new information? - -Change the serial number in the SOA for any domains that you modified and -restart named. Wait an hour and check again. The information propogates -out. It won't change immediately. - - -My local machine knows about all the name server information, but no other -sites know about me? - -Find an upstream nameserver (one that has an SOA for something in your -domain) and ask them to be a secondary name server for you. eg if you are -ecel.uwa.edu.au, ask someone who has an SOA for the domain uwa.edu.au. -Get NS records (and glue) added to your parent zone for your zone. This is -called delegating. It should be done formally like this or you will get -inconsistant answers out of the DNS. ALL NAMSERVERS FOR YOUR ZONE SHOULD -BE LISTED IN THIS MANNER. - - -My forward domain names work, but the backward names do not? - -Make sure the numbers are back to front and have the in-addr.arpa on the -end. -Make sure you reverse zone is registered. For Class C nets this can be done -by mailing to hostmaster@internic.net. For class A & B nets make sure that -you are registeres with the primary for your net and that the net itself -is registered with hostmaster@internic.net. - - -How to get useful information from nslookup: - -Nslookup is a very useful program but I'm sure there are less than 20 -people worldwide who know how to use it to its full usefulness. I'm most -certainly not one of them. If you don't like using nslookup, there is at -least one other program called dig, that has most/all(?) of the -functionality of nslookup and is a hell of a lot easier to use. - -I won't go into dig much here except to say that it is a lot easier to get -this information out of. I won't bother because nslookup ships with almost -all machines that come with network software. - -To run nslookup, you usually just type nslookup. It will tell you the -server it connects to. You can specify a different server if you want. -This is useful when you want to tell if your named information is -consistent with other servers. - -Getting name to number mappings. - -Type the name of the machine. Typing 'decel' is enough if the machine is -local. - -(Once you have run nslookup successfully) -> decel -Server: ecel.uwa.edu.au -Address: 130.95.4.2 - -Name: decel.ecel.uwa.edu.au -Address: 130.95.4.2 - -> - -One curious quirk of some name resolvers is that if you type a -machine name, they will try a number of permutations. For example if my -machine is in the domain ecel.uwa.edu.au and I try to find a machine -called fred, the resolver will try the following. - - fred.ecel.uwa.edu.au. - fred.uwa.edu.au. - fred.edu.au. - fred.au. - fred. - -This can be useful, but more often than not, you would simply prefer a good -way to make aliases for machines that are commonly referenced. If you are -running resolv+, you should just be able to put common machines into the -host file. - -DIG: dig <machine name> - -Getting number to name mappings. - -Nslookup defaults to finding you the Address of the name specified. For -reverse lookups you already have the address and you want to find the -name that goes with it. If you read and understood the bit above where it -describes how to create the number to name mapping file, you would guess -that you need to find the PTR record instead of the A record. So you do -the following. - -> set type=ptr -> 2.4.95.130.in-addr.arpa -Server: decel.ecel.uwa.edu.au -Address: 130.95.4.2 - -2.4.95.130.in-addr.arpa host name = decel.ecel.uwa.edu.au -> - -nslookup tells you that the ptr for the machine name -2.4.95.130.in-addr.arpa points to the host decel.ecel.uwa.edu.au. - -DIG: dig -x <machine number> - -Finding where mail goes when a machine has no IP number. - -When a machine is not IP connected, it needs to specify to the world, where -to send the mail so that it can dial up and collect it every now and then. -This is accomplished by setting up an MX record for the site and not giving -it an IP number. To get the information out of nslookup as to where the -mail goes, do the following. - -> set type=mx -> dialix.oz.au -Server: decel.ecel.uwa.oz.au -Address: 130.95.4.2 - -Non-authoritative answer: -dialix.oz.au preference = 100, mail exchanger = uniwa.uwa.OZ.AU -dialix.oz.au preference = 200, mail exchanger = munnari.OZ.AU -Authoritative answers can be found from: -uniwa.uwa.OZ.AU inet address = 130.95.128.1 -munnari.OZ.AU inet address = 128.250.1.21 -munnari.OZ.AU inet address = 192.43.207.1 -mulga.cs.mu.OZ.AU inet address = 128.250.35.21 -mulga.cs.mu.OZ.AU inet address = 192.43.207.2 -dmssyd.syd.dms.CSIRO.AU inet address = 130.155.16.1 -ns.UU.NET inet address = 137.39.1.3 - -You tell nslookup that you want to search for mx records and then you give -it the name of the machine. It tells you the preference for the mail -(small means more preferable), and who the mail should be sent to. It also -includes sites that are authorative (have this name in their named database -files) for this MX record. There are multiple sites as a backup. As can -be seen, our local public internet access company dialix would like all of -their mail to be sent to uniwa, where they collect it from. If uniwa is -not up, send it to munnari and munnari will get it to uniwa eventually. - -NOTE: For historical reasons Australia used to be .oz which was changed to -.oz.au to move to the ISO standard extensions upon the advent of IP.

If your system is too old to have a /var, either create -one or use /usr/local/adm/named instead. Put your named.boot in it, and make -/etc/named.boot a symlink to it. If your system doesn't have symlinks, you're -S-O-L (but you knew that). In named.boot, put a "directory" directive that -specifies your actual BIND working directory: - - directory /var/named - -All relative pathnames used in "primary", "secondary", and "cache" directives -will be evaluated relative to this directory. Create two subdirectories, -/var/named/pri and /var/named/sec. Whenever you add a "primary" directive -to your named.boot, use "pri/WHATEVER" as the path name. And then put the -primary zone file into "pri/WHATEVER". Likewise when you add "secondary" -directives, use "sec/WHATEVER" and BIND (really named-xfer) will create the -files in that subdirectory. - -(Variations: (1) make a midlevel directory "zones" and put "pri" and "sec" -into it; (2) if you tend to pick up a lot of secondaries from a few hosts, -group them together in their own subdirectories -- something like -/var/named/zones/uucp if you're a UUCP Project name server.) - -For your forward files, name them after the zone. dec.com becomes -"/var/named/zones/pri/dec.com".

This leaves room for names longer than 7 bytes without messing up the -columns.

Some folks seem to prefer to -group "MX" and the priority together in one tab stop. While this looks neat -it's very confusing to newcomers and for them it violates the law of least -astonishment. - -If you have a multi-level zone (one which contains names that have dots in -them), you can use additional $ORIGIN statements but I recommend against it -since there is no "back" operator. That is, given the above example you can -add: - -============= -$ORIGIN home -gw A 192.5.5.1 -============= - -The problem with this is that subsequent RR's had better be somewhere under -the "home.vix.com" name or else the $ORIGIN that introduces them will have -to use a fully qualified name.

If there where - any pubkey declarations in the input boot file they will be - deleted. - Signer generates files that correspond to the load files specified. - - In case of load file that $INCLUDEs another load file, signer will - merge them to the output file. - You will notice that the output files are significantly larger. - The output files will be in a different order than the input files, - all records are sorted into DNSSEC sort order. - NXT and SIG records have been added. - - If there are any NS records for a name other than the zone name of - each input file you will see messages that NULL KEY records - have been created, if this is not correct behavior, add - the correct KEY RRs. - For each domain name that has a NS record but is not a zone name - of load file you will see a file named <name>.PARENT, - this file contains the KEY record for that name and an - NXT record + 2 SIG records. - This file needs to be sent to the nameserver that is primary for that - zone. There are two reasons for this: - 1. To support Certification Hierarchy, each zone key is - signed by the parent zone key. - 2. Zone is the most trustworthy source for itself unless - these records are loaded into the primary server for - the zone, the records may not get propagated. - -how to run SEC_NAMED: - -Included in the distribution there is a small test setup: - -# run signer -./signer boot-f simple_test/test.boot [out-dir /tmp] -# or -make test -# This takes few minutes to run depending on your machine and the size -# of the key selected -# all output files will be stored in /tmp unless out-dir is specified - -# -# Now we are ready to run named -cd ../named -./named -p 12345 -b /tmp/test.boot.save [-d x] - -# -# you can now check for data in the data base -# using the new dig. -# -cd ../tools -./dig @yourhost snore.foo.bar. any in -p 12345 - -# -# Output from new dig will be something like this -# -; <<>> DiG 2.1 <<>> @dnssrv snore.foo.bar. any in -p -; (1 server found) -;; res options: init recurs defnam dnsrch -;; got answer: -;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10 -;; flags: qr rd ra; Ques: 1, Ans: 11, Auth: 0, Addit: 1 -;; QUESTIONS: -;; snore.foo.bar, type = ANY, class = IN - -;; ANSWERS: -snore.foo.bar. 259200 A 10.17.3.20 -snore.foo.bar. 259200 SIG A ( - 1 3; alg labels - 259200 ; TTL - 19950506200636 ; Signature expiration - 19950406200659 ; time signed - 47437 ; Key foot print - foo.bar. ; Signers name - FsqeW3hstM8Q6v8PMCGPsVMfO6dEpHjFgKm2dJRaofFtCQ/CT9O6Vo7J5zgkV+5ciWQwuZwvzW071jnZ1i27Ip/8vqdKGHC63tjWkCHSZV0= - ) ; END Signature -snore.foo.bar. 259200 MX 96 who.foo.bar. -snore.foo.bar. 259200 MX 100 foo.bar. -snore.foo.bar. 259200 MX 120 xxx.foo.bar. -snore.foo.bar. 259200 MX 130 maGellan.foo.bar. -snore.foo.bar. 259200 MX 140 bozo.foo.bar. -snore.foo.bar. 259200 SIG MX ( - 1 3; alg labels - 259200 ; TTL - 19950506200636 ; Signature expiration - 19950406200659 ; time signed - 47437 ; Key foot print - foo.bar. ; Signers name - EV0cJqF3pUOgktggTrFf55YGwQFbUqPJAMTnAkHK3+Z/Ya6GgwwNOGRzq/FYm5P4E+yIj6WUYFh9Ex5eX5TwiIsjM/hy173lSa3qm/ljDk8= - ) ; END Signature -snore.foo.bar. 259200 NXT xxx.foo.bar. -snore.foo.bar. 259200 SIG NXT ( - 1 3; alg labels - 259200 ; TTL - 19950506200636 ; Signature expiration - 19950406200659 ; time signed - 47437 ; Key foot print - foo.bar. ; Signers name - eJUHVm5Q5qYQYFVOW0L5Of67HQvQ9+7T7sQqHv7ayTT2sMnXudxviYv43vALMMwBcJFXFEhLhwYwN7pUDssD/w5si/6JJQTi1o30S8si3zE= - ) ; END Signature - -;; Total query time: 195 msec -;; FROM: dnssrv to SERVER: dnssrv 10.17.3.1 -;; WHEN: Thu Apr 6 16:20:32 1995 -;; MSG SIZE sent: 31 rcvd: 662 diff --git a/contrib/bind/lib/inet/hostnamelen.c b/contrib/bind/lib/inet/hostnamelen.c deleted file mode 100644 index 93880627fda2..000000000000 --- a/contrib/bind/lib/inet/hostnamelen.c +++ /dev/null @@ -1,94 +0,0 @@ -/* - * ++Copyright++ 1995 - * - - * Copyright (c) 1995 - * The Regents of the University of California.

All query options are -accessible from the command line. -.PP -The usual simple use of \fIdig\fP will take the form: -.sp 1 - dig @server domain query-type query-class -.sp 1 -where: -.IP \fIserver\fP -may be either a domain name or a dot-notation -Internet address. If this optional field is omitted, \fIdig\fP -will attempt to use the default name server for your machine. -.sp 1 -\fBNote:\fP If a domain name is specified, this will be resolved -using the domain name system resolver (i.e., BIND). If your -system does not support DNS, you may \fIhave\fP to specify a -dot-notation address. Alternatively, if there is a server -at your disposal somewhere, all that is required is that -/etc/resolv.conf be present and indicate where the default -name servers reside, so that \fIserver\fP itself can be -resolved. See -.IR resolver (@FORMAT_EXT@) -for information on /etc/resolv.conf. -(WARNING: Changing /etc/resolv.conf will affect -the standard resolver library and potentially several -programs which use it.) As an option, the user may set the -environment variable LOCALRES to name a file which is to -be used instead of /etc/resolv.conf (LOCALRES is specific -to the \fIdig\fP resolver and not referenced by the standard -resolver). If the LOCALRES variable is not set or the file -is not readable then /etc/resolv.conf will be used. -.IP \fIdomain\fP -is the domain name for which you are requesting information. -See OPTIONS [-x] for convenient way to specify inverse address -query. -.IP \fIquery-type\fP -is the type of information (DNS query type) that -you are requesting. If omitted, the default is "a" (T_A = address). -The following types are recognized: -.sp 1 -.ta \w'hinfoXX'u +\w'T_HINFOXX'u -.nf -a T_A network address -any T_ANY all/any information about specified domain -mx T_MX mail exchanger for the domain -ns T_NS name servers -soa T_SOA zone of authority record -hinfo T_HINFO host information -axfr T_AXFR zone transfer - (must ask an authoritative server) -txt T_TXT arbitrary number of strings -.fi -.sp 1 -(See RFC 1035 for the complete list.) -.IP \fIquery-class\fP -is the network class requested in the query. If -omitted, the default is "in" (C_IN = Internet). -The following classes are recognized: -.sp 1 -.ta \w'hinfoXX'u +\w'T_HINFOXX'u -.nf -in C_IN Internet class domain -any C_ANY all/any class information -.fi -.sp 1 -(See RFC 1035 for the complete list.) -.sp 1 -\fBNote:\fP -"Any" can be used to specify a class and/or a type of -query. \fIDig\fP will parse the first occurrence of "any" -to mean query-type = T_ANY. To specify query-class = -C_ANY you must either specify "any" twice, or set -query-class using "\-c" option (see below). -.SH OTHER OPTIONS -.IP "%ignored-comment" -"%" is used to included an argument that is simply not -parsed. This may be useful if running \fIdig\fP in batch -mode. Instead of resolving every @server-domain-name in -a list of queries, you can avoid the overhead of doing -so, and still have the domain name on the command line -as a reference. Example: -.sp 1 - dig @128.9.0.32 %venera.isi.edu mx isi.edu -.sp 1 -.IP "\-<dig option>" -"\-" is used to specify an option which effects the -operation of \fIdig\fP. The following options are currently -available (although not guaranteed to be useful): -.RS -.IP "\-x \fIdot-notation-address\fP" -Convenient form to specify inverse address mapping. -Instead of "dig 32.0.9.128.in-addr.arpa" one can -simply "dig -x 128.9.0.32". -.IP "\-f \fIfile\fP" -File for \fIdig\fP batch mode. The file contains a list -of query specifications (\fIdig\fP command lines) which -are to be executed successively. Lines beginning -with ';', '#', or '\\n' are ignored. Other options -may still appear on command line, and will be in -effect for each batch query. -.IP "\-T \fItime\fP" -Time in seconds between start of successive -queries when running in batch mode. Can be used -to keep two or more batch \fIdig\fP commands running -roughly in sync. Default is zero. -.IP "\-p \fIport\fP" -Port number. Query a name server listening to a -non-standard port number. Default is 53. -.IP "\-P[\fIping-string\fP]" -After query returns, execute a -.IR ping (@SYS_OPS_EXT@) -command -for response time comparison. This rather -inelegantly makes a call to the shell. The last -three lines of statistics is printed for the -command: -.sp 1 - ping \-s server_name 56 3 -.sp 1 -If the optional "ping string" is present, it -replaces "ping \-s" in the shell command. -.IP "\-t \fIquery-type\fP" -Specify type of query. May specify either an -integer value to be included in the type field -or use the abbreviated mnemonic as discussed -above (i.e., mx = T_MX). -.IP "\-c \fIquery-class\fP" -Specify class of query. May specify either an -integer value to be included in the class field -or use the abbreviated mnemonic as discussed -above (i.e., in = C_IN). -.IP "\-envsav" -This flag specifies that the \fIdig\fP environment -(defaults, print options, etc.), after -all of the arguments are parsed, should be saved -to a file to become the default environment. -Useful if you do not like the standard set of -defaults and do not desire to include a -large number of options each time \fIdig\fP is used. -The environment consists of resolver state -variable flags, timeout, and retries as well as -the flags detailing \fIdig\fP output (see below). -If the shell environment variable LOCALDEF is set -to the name of a file, this is where the default -\fIdig\fP environment is saved. If not, the file -"DiG.env" is created in the current working directory. -.sp 1 -\fBNote:\fP LOCALDEF is specific to the \fIdig\fP resolver, -and will not affect operation of the standard -resolver library. -.sp 1 -Each time \fIdig\fP is executed, it looks for "./DiG.env" -or the file specified by the shell environment variable -LOCALDEF. If such file exists and is readable, then the -environment is restored from this file -before any arguments are parsed. -.IP "\-envset" -This flag only affects -batch query runs. When "\-envset" is -specified on a line in a \fIdig\fP batch file, -the \fIdig\fP environment after the arguments are parsed, -becomes the default environment for the duration of -the batch file, or until the next line which specifies -"\-envset". -.IP "\-[no]stick" -This flag only affects batch query runs. -It specifies that the \fIdig\fP environment (as read initially -or set by "\-envset" switch) is to be restored before each query -(line) in a \fIdig\fP batch file. -The default "\-nostick" means that the \fIdig\fP environment -does not stick, hence options specified on a single line -in a \fIdig\fP batch file will remain in effect for -subsequent lines (i.e. they are not restored to the -"sticky" default). - -.RE -.IP "+<query option>" -"+" is used to specify an option to be changed in the -query packet or to change \fIdig\fP output specifics. Many -of these are the same parameters accepted by -.IR nslookup (@SYS_OPS_EXT@). -If an option requires a parameter, the form is as -follows: -.sp 1 - +keyword[=value] -.sp 1 -Most keywords can be abbreviated. Parsing of the "+" -options is very simplistic \(em a value must not be -separated from its keyword by white space.

BIND's resolver has (as of BIND 4.9) been augmented to work -properly with \fIDig\fP. Essentially, \fIDig\fP is a straight-forward -(albeit not pretty) effort of parsing arguments and setting appropriate -parameters. \fIDig\fP uses resolver routines res_init(), res_mkquery(), -res_send() as well as accessing _res structure. -.SH FILES -.ta \w'/etc/resolv.confXX'u -/etc/resolv.conf initial domain name and name server -\./DiG.env default save file for default options -.br - addresses -.SH ENVIRONMENT -LOCALRES file to use in place of /etc/resolv.conf -.br -LOCALDEF default environment file -.SH AUTHOR -Steve Hotz -hotz@isi.edu -.SH ACKNOWLEDGMENTS -\fIDig\fP uses functions from -.IR nslookup (@SYS_OPS_EXT@) -authored by Andrew Cherenson. -.SH BUGS -\fIDig\fP has a serious case of "creeping featurism" -- the result of -considering several potential uses during it's development. It would -probably benefit from a rigorous diet. Similarly, the print flags -and granularity of the items they specify make evident their -rather ad hoc genesis. -.PP -\fIDig\fP does not consistently exit nicely (with appropriate status) -when a problem occurs somewhere in the resolver (NOTE: most of the common -exit cases are handled). This is particularly annoying when running in -batch mode. If it exits abnormally (and is not caught), the entire -batch aborts; when such an event is trapped, \fIdig\fP simply -continues with the next query. -.SH SEE ALSO -@INDOT@named(@SYS_OPS_EXT@), resolver(@LIB_NETWORK_EXT@), resolver(@FORMAT_EXT@), nslookup(@SYS_OPS_EXT@) diff --git a/contrib/bind/man/dnsquery.1 b/contrib/bind/man/dnsquery.1 deleted file mode 100644 index 510053ab3438..000000000000 --- a/contrib/bind/man/dnsquery.1 +++ /dev/null @@ -1,164 +0,0 @@ -.TH DNSQUERY @CMD_EXT_U@ "10 March 1990" -.UC 6 -.SH NAME -dnsquery \- query domain name servers using resolver -.SH SYNOPSIS -.B dnsquery -[-n -.I nameserver] -[-t -.I type] -[-c -.I class] -[-r -.I retry] -[-p -.I retry period] -[-d] [-s] [-v] host -.SH DESCRIPTION -The -.IR dnsquery -program is a general interface to nameservers via -BIND resolver library calls.

It gets this information -from a set of interconnected servers that are spread across the -country. By default, it simply converts between host names and -Internet addresses. However with the -t or -a options, it can be used -to find all of the information about this host that is maintained -by the domain server. -.PP -The arguments can be either host names or host numbers. The program -first attempts to interpret them as host numbers. If this fails, -it will treat them as host names. A host number consists of -first decimal numbers separated by dots, e.g. 128.6.4.194 -A host name -consists of names separated by dots, e.g. topaz.rutgers.edu. -Unless the name ends in a dot, the local domain -is automatically tacked on the end. Thus a Rutgers user can say -"host topaz", and it will actually look up "topaz.rutgers.edu". -If this fails, the name is tried unchanged (in this case, "topaz"). -This same convention is used for mail and other network utilities. -The actual suffix to tack on the end is obtained -by looking at the results of a "hostname" call, and using everything -starting at the first dot. (See below for a description of -how to customize the host name lookup.) -.PP -The first argument is the host name you want to look up. -If this is a number, an "inverse query" is done, i.e. the domain -system looks in a separate set of databases used to convert numbers -to names. -.PP -The second argument is optional. It -allows you to specify a particular server to query. If you don't -specify this argument, the default server (normally the local machine) -is used. -.PP -If a name is specified, you may see output of three different kinds. -Here is an example that shows all of them: -.br - % host sun4 -.br - sun4.rutgers.edu is a nickname for ATHOS.RUTGERS.EDU -.br - ATHOS.RUTGERS.EDU has address 128.6.5.46 -.br - ATHOS.RUTGERS.EDU has address 128.6.4.4 -.br - ATHOS.RUTGERS.EDU mail is handled by ARAMIS.RUTGERS.EDU -.br -The user has typed the command "host sun4". The first line indicates -that the name "sun4.rutgers.edu" is actually a nickname. The official -host name is "ATHOS.RUTGERS.EDU'. The next two lines show the -address. If a system has more than one network interface, there -will be a separate address for each. The last line indicates -that ATHOS.RUTGERS.EDU does not receive its own mail. Mail for -it is taken by ARAMIS.RUTGERS.EDU. There may be more than one -such line, since some systems have more than one other system -that will handle mail for them. Technically, every system that -can receive mail is supposed to have an entry of this kind. If -the system receives its own mail, there should be an entry -the mentions the system itself, for example -"XXX mail is handled by XXX". However many systems that receive -their own mail do not bother to mention that fact. If a system -has a "mail is handled by" entry, but no address, this indicates -that it is not really part of the Internet, but a system that is -on the network will forward mail to it. Systems on Usenet, Bitnet, -and a number of other networks have entries of this kind. -.PP -There are a number of options that can be used before the -host name. Most of these options are meaningful only to the -staff who have to maintain the domain database. -.PP -The option -w causes host to wait forever for a response. Normally -it will time out after around a minute. -.PP -The option -v causes printout to be in a "verbose" format. This -is the official domain master file format, which is documented -in the man page for "named". Without this option, output still follows -this format in general terms, but some attempt is made to make it -more intelligible to normal users. Without -v, -"a", "mx", and "cname" records -are written out as "has address", "mail is handled by", and -"is a nickname for", and TTL and class fields are not shown. -.PP -The option -r causes recursion to be turned off in the request. -This means that the name server will return only data it has in -its own database. It will not ask other servers for more -information. -.PP -The option -d turns on debugging. Network transactions are shown -in detail. -.PP -The option -t allows you to specify a particular type of information -to be looked up. The arguments are defined in the man page for -"named". Currently supported types are a, ns, md, mf, cname, -soa, mb, mg, mr, null, wks, ptr, hinfo, minfo, mx, uinfo, -uid, gid, unspec, and the wildcard, which may be written -as either "any" or "*". Types must be given in lower case. -Note that the default is to look first for "a", and then "mx", except -that if the verbose option is turned on, the default is only "a". -.PP -The option -a (for "all") is equivalent to "-v -t any". -.PP -The option -l causes a listing of a complete domain. E.g. -.br - host -l rutgers.edu -.br -will give a listing of all hosts in the rutgers.edu domain. The -t -option is used to filter what information is presented, as you -would expect. The default is address information, which also -include PTR and NS records. The command -.br - host -l -v -t any rutgers.edu -.br -will give a complete download of the zone data for rutgers.edu, -in the official master file format. (However the SOA record is -listed twice, for arcane reasons.) NOTE: -l is implemented by -doing a complete zone transfer and then filtering out the information -the you have asked for. This command should be used only if it -is absolutely necessary. -.SH CUSTOMIZING HOST NAME LOOKUP -In general, if the name supplied by the user does not -have any dots in it, a default domain is appended to the end. -This domain can be defined in /etc/resolv.conf, but is normally derived -by taking the local hostname after its first dot. The user can override -this, and specify a different default domain, using the environment -variable -.IR LOCALDOMAIN . -In addition, the user can supply his own abbreviations for host names. -They should be in a file consisting of one line per abbreviation. -Each line contains an abbreviation, a space, and then the full -host name. This file must be pointed to by an environment variable -.IR HOSTALIASES , -which is the name of the file. -.SH "See Also" -@INDOT@named (@SYS_OPS_EXT@) -.SH BUGS -Unexpected effects can happen when you type a name that is not -part of the local domain. Please always keep in mind the -fact that the local domain name is tacked onto the end of every -name, unless it ends in a dot. Only if this fails is the name -used unchanged. -.PP -The -l option only tries the first name server listed for the -domain that you have requested. If this server is dead, you -may need to specify a server manually. E.g. to get a listing -of foo.edu, you could try "host -t ns foo.edu" to get a list -of all the name servers for foo.edu, and then try "host -l foo.edu xxx" -for all xxx on the list of name servers, until you find one that -works. diff --git a/contrib/bind/man/hostname.7 b/contrib/bind/man/hostname.7 deleted file mode 100644 index 255c53cfe44d..000000000000 --- a/contrib/bind/man/hostname.7 +++ /dev/null @@ -1,108 +0,0 @@ -.\" Copyright (c) 1987 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" Redistribution and use in source and binary forms are permitted -.\" provided that the above copyright notice and this paragraph are -.\" duplicated in all such forms and that any documentation, -.\" advertising materials, and other materials related to such -.\" distribution and use acknowledge that the software was developed -.\" by the University of California, Berkeley.

A domain is a hierarchical, dot-separated list -of subdomains. For example, the machine \fImonet\fP, in the \fIBerkeley\fP -subdomain of the \fIEDU\fP subdomain of the Internet Domain Name System -would be represented as -.br - \fImonet\fP.\fIBerkeley\fP.\fIEDU\fP -.br -(with no trailing dot). -.PP -Hostnames are often used with network client and server programs, -which must generally translate the name to an address for use. -(This task is usually performed by the library routine -.IR gethostbyname (@LIB_NETWORK_EXT@).) -The default method for resolving hostnames by the Internet name resolver is -to follow \s-1RFC\s+1 1535's security recommendations. Actions can be taken -by the administrator to override these recommendations and to have the -resolver behave the same as earlier, non-\s-1RFC\s+1 1535 resolvers. -.PP -The default method (using \s-1RFC\s+1 1535 guidelines) follows: -.PP -If the name consists of a single component, i.e. contains no dot, and if the -environment variable ``\s-1HOSTALIASES\s+1'' is set to the name of a file, -that file is searched for a string matching the input hostname. The file -should consist of lines made up of two strings separated by white-space, the -first of which is the hostname alias, and the second of which is the complete -hostname to be substituted for that alias. If a case-insensitive match is -found between the hostname to be resolved and the first field of a line in -the file, the substituted name is looked up with no further processing. -.PP -If there is at least one dot in the name, then the name is first tried as -is. The number of dots to cause this action is configurable by setting the -threshold using the ``\fIndots\fP'' option in -.I /etc/resolv.conf -(default: \fI1\fP). If the name ends with a dot, the trailing dot is -removed, and the remaining name is looked up (regardless of the setting of -the 'ndots' option) and no further processing is done. -.PP -If the input name does not end with a trailing dot, it is looked up by -searching through a list of domains until a match is found. If neither the -search option in the -.I /etc/resolv.conf -file or the ``\s-1LOCALDOMAIN\s+1'' environment variable is used, then the -search list of domains contains only the full domain specified by the domain -option (in -.IR /etc/resolv.conf ) -or the domain used in the local hostname (see -.IR hostname (@CMD_EXT@) -and -.IR resolver (@FORMAT_EXT@)). -For example, if the ``\fIdomain\fP'' option is set to \fICS.Berkeley.EDU\fP, -then only CS.Berkeley.EDU will be in the search list and will be the only -domain appended to the partial hostname, for example, ``\fIlithium\fP'', -making \fIlithium.CS.Berkeley.EDU\fP the only name to be tried using the -search list. -.PP -If the search option is used in -.I /etc/resolv.conf -or the environment variable, ``\s-1LOCALDOMAIN\s+1'' is set by the user, then -the search list will include what is set by these methods. For -example, if the ``\fIsearch\fP'' option contained -.br - \fICS.Berkeley.EDU CChem.Berkeley.EDU Berkeley.EDU\fP -.br -then the partial hostname (e.g., ``\fIlithium\fP'') will be tried with each -domainname appended (in the same order specified). The resulting hostnames -that would be tried are: -.nf - \fIlithium.CS.Berkeley.EDU\fP - \fIlithium.CChem.Berkeley.EDU\fP - \fIlithium.Berkeley.EDU\fP -.fi -.PP -The environment variable ``\s-1LOCALDOMAIN\s+1'' overrides the -``\fIsearch\fP'' and ``\fIdomain\fP'' options, and if both search and domain -options are present in the resolver configuration file, then only the last -one listed is used (see -.IR resolver (@FORMAT_EXT@)). -.PP -If the name was not previously tried ``as is'' (i.e., it fell below the -``\fIndots\fP'' threshold or did not contain a dot), then the name as -originally provided is attempted. -.SH SEE ALSO -.IR gethostbyname (@LIB_NETWORK_EXT@), -.IR resolver (@FORMAT_EXT@), -.IR mailaddr (@DESC_EXT@), -.IR @INDOT@named (@SYS_OPS_EXT@) diff --git a/contrib/bind/man/mailaddr.7 b/contrib/bind/man/mailaddr.7 deleted file mode 100644 index 9a69a4ddbe7c..000000000000 --- a/contrib/bind/man/mailaddr.7 +++ /dev/null @@ -1,135 +0,0 @@ -.\" Copyright (c) 1983, 1987 The Regents of the University of California. -.\" All rights reserved. -.\" -.\" Redistribution and use in source and binary forms are permitted -.\" provided that the above copyright notice and this paragraph are -.\" duplicated in all such forms and that any documentation, -.\" advertising materials, and other materials related to such -.\" distribution and use acknowledge that the software was developed -.\" by the University of California, Berkeley.

These addresses are in the general format -.PP - user@domain -.PP -where a domain is a hierarchical dot separated list of subdomains. For -example, the address -.PP - eric@monet.berkeley.edu -.PP -is normally interpreted from right to left: the message should go to the -ARPA name tables (which do not correspond exactly to the physical ARPANET), -then to the Berkeley gateway, after which it should go to the local host -monet. When the message reaches monet it is delivered to the user ``eric''. -.PP -Unlike some other forms of addressing, this does not imply any routing. -Thus, although this address is specified as an ARPA address, it might -travel by an alternate route if that were more convenient or efficient. -For example, at Berkeley, the associated message would probably go directly -to monet over the Ethernet rather than going via the Berkeley ARPANET -gateway. -.SS Abbreviation. -.PP -Under certain circumstances it may not be necessary to type the entire -domain name. In general, anything following the first dot may be omitted -if it is the same as the domain from which you are sending the message. -For example, a user on ``calder.berkeley.edu'' could send to ``eric@monet'' -without adding the ``berkeley.edu'' since it is the same on both sending -and receiving hosts. -.PP -Certain other abbreviations may be permitted as special cases. For -example, at Berkeley, ARPANET hosts may be referenced without adding -the ``berkeley.edu'' as long as their names do not conflict with a local -host name. -.SS Compatibility. -.PP -Certain old address formats are converted to the new format to provide -compatibility with the previous mail system. In particular, -.PP - user@host.ARPA -.PP -is allowed and -.PP - host:user -.PP -is converted to -.PP - user@host -.PP -to be consistent with the \fIrcp\fP(@CMD_EXT@) command. -.PP -Also, the syntax -.PP - host!user -.PP -is converted to: -.PP - user@host.UUCP -.PP -This is normally converted back to the ``host!user'' form before being sent -on for compatibility with older UUCP hosts. -.PP -The current implementation is not able to route messages automatically through -the UUCP network. Until that time you must explicitly tell the mail system -which hosts to send your message through to get to your final destination. -.SS Case Distinctions. -.PP -Domain names (i.e., anything after the ``@'' sign) may be given in any mixture -of upper and lower case with the exception of UUCP hostnames. Most hosts -accept any combination of case in user names, with the notable exception of -MULTICS sites. -.SS Route-addrs. -.PP -Under some circumstances it may be necessary to route a message through -several hosts to get it to the final destination. Normally this routing -is done automatically, but sometimes it is desirable to route the message -manually. Addresses which show these relays are termed ``route-addrs.'' -These use the syntax: -.PP - <@hosta,@hostb:user@hostc> -.PP -This specifies that the message should be sent to hosta, from there to hostb, -and finally to hostc. This path is forced even if there is a more efficient -path to hostc. -.PP -Route-addrs occur frequently on return addresses, since these are generally -augmented by the software at each host. It is generally possible to ignore -all but the ``user@domain'' part of the address to determine the actual -sender. -.SS Postmaster. -.PP -Every site is required to have a user or user alias designated ``postmaster'' -to which problems with the mail system may be addressed. -.SS Other Networks. -.PP -Some other networks can be reached by giving the name of the network as the -last component of the domain. \fIThis is not a standard feature\fP and may -not be supported at all sites. For example, messages to CSNET or BITNET sites -can often be sent to ``user@host.CSNET'' or ``user@host.BITNET'' respectively. -.SH BUGS -The RFC822 group syntax (``group:user1,user2,user3;'') is not supported -except in the special case of ``group:;'' because of a conflict with old -berknet-style addresses. -.PP -Route-Address syntax is grotty. -.PP -UUCP- and ARPANET-style addresses do not coexist politely. -.SH SEE ALSO -mail(@CMD_EXT@), sendmail(@SYS_OPS_EXT@); -Crocker, D.

Without any arguments, -.I named -will read the default boot file -.IR /etc/named.boot , -read any initial data and listen for queries. -.PP -Options are: -.TP -.B \-d -Print debugging information. -A number after the ``d'' determines the level of -messages printed. -.TP -.B \-p -Use nonstandard port numbers. The default is the standard port number -as returned by getservbyname(@LIB_NETWORK_EXT@) for service ``domain''. -The argument can specify two port numbers separated by a slash (``\fB/\fP'') -in which case the first port is that used when contacting remote servers, -and the second one is the service port bound by the local instance of -.IR named . -This is used mostly for debugging purposes. -.TP -.B \-b -Use an alternate boot file. This is optional and allows you to -specify a file with a leading dash. -.TP -.B \-q -Trace all incoming queries if \fInamed\fP has been compiled with -\fIQRYLOG\fP defined. \fINOTE:\fP this option is deprecated in favour -of the boot file directive ``options query-log''. -.TP -.B \-r -Turns recursion off in the server. Answers can come only from local -(primary or secondary) zones. This can be used on root servers. -\fINOTE:\fP this option is deprecated in favour -of the boot file directive ``options no-recursion''. -.PP -Any additional argument is taken as the name of the boot file. -If multiple boot files are specified, only the last is used. -.PP -The boot file contains information about where the name server is to get -its initial data. -Lines in the boot file cannot be continued on subsequent lines. -The following is a small example: -.in +2m -.nf - -; -; boot file for name server -; -directory /usr/local/adm/named - -.ta \w'check-names\ 'u +\w'6.32.128.IN-ADDR.ARPA\ 'u +\w'128.32.137.8 128.32.137.3\ 'u -; type domain source host/file backup file - -cache . root.cache -primary Berkeley.EDU berkeley.edu.zone -primary 32.128.IN-ADDR.ARPA ucbhosts.rev -secondary CC.Berkeley.EDU 128.32.137.8 128.32.137.3 cc.zone.bak -secondary 6.32.128.IN-ADDR.ARPA 128.32.137.8 128.32.137.3 cc.rev.bak -primary 0.0.127.IN-ADDR.ARPA localhost.rev -forwarders 10.0.0.78 10.2.0.78 -limit transfers-in 10 -limit datasize 64M -limit files 256 -options forward-only query-log fake-iquery -check-names primary fail -check-names secondary warn -check-names response ignore - -.DT -.fi -.in -The ``directory'' line causes the server to change its working directory to -the directory specified. This can be important for the correct processing -of \s-1$INCLUDE\s+1 files in primary zone files. -.LP -The ``cache'' line specifies that data in ``root.cache'' is to be placed in -the backup cache. Its main use is to specify data such as locations of root -domain servers. This cache is not used during normal operation, but is used -as ``hints'' to find the current root servers. The file ``root.cache'' is -in the same format as ``berkeley.edu.zone''. There can be more than one -``cache'' file specified. The ``root.cache'' file should be retrieved -periodically from \s-1FTP.RS.INTERNIC.NET\s+1 since it contains a list of -root servers, and this list changes periodically. -.LP -The first example ``primary'' line states that the file -``berkeley.edu.zone'' contains authoritative data for the ``Berkeley.EDU'' -zone. The file ``berkeley.edu.zone'' contains data in the master file -format described in RFC 883. All domain names are relative to the origin, in -this case, ``Berkeley.EDU'' (see below for a more detailed description). -The second ``primary'' line states that the file ``ucbhosts.rev'' contains -authoritative data for the domain ``32.128.IN-ADDR.ARPA,'' which is used to -translate addresses in network 128.32 to hostnames. Each master file should -begin with an SOA record for the zone (see below). -.LP -The first example ``secondary'' line specifies that all authoritative data -under ``CC.Berkeley.EDU'' is to be transferred from the name server at -128.32.137.8. If the transfer fails it will try 128.32.137.3 and continue -trying the addresses, up to 10, listed on this line. The secondary copy is -also authoritative for the specified domain. The first non-dotted-quad -address on this line will be taken as a filename in which to backup the -transferred zone. The name server will load the zone from this backup file -if it exists when it boots, providing a complete copy even if the master -servers are unreachable. Whenever a new copy of the domain is received by -automatic zone transfer from one of the master servers, this file will be -updated. If no file name is given, a temporary file will be used, and will -be deleted after each successful zone transfer. This is not recommended -since it is a needless waste of bandwidth. The second example ``secondary'' -line states that the address-to-hostname mapping for the subnet 128.32.136 -should be obtained from the same list of master servers as the previous zone. -.LP -The ``forwarders'' line specifies the addresses of sitewide servers that -will accept recursive queries from other servers. If the boot file -specifies one or more forwarders, then the server will send all queries for -data not in the cache to the forwarders first. Each forwarder will be asked -in turn until an answer is returned or the list is exhausted. If no answer -is forthcoming from a forwarder, the server will continue as it would have -without the forwarders line unless it is in ``forward-only'' mode. The -forwarding facility is useful to cause a large sitewide cache to be -generated on a master, and to reduce traffic over links to outside servers. -It can also be used to allow servers to run that do not have direct access -to the Internet, but wish to look up exterior names anyway. -.LP -The ``slave'' line (deprecated) is allowed for backward compatibility. Its -meaning is identical to ``options forward-only''. -.LP -The ``sortlist'' line can be used to indicate networks that are to be -preferred over other networks. Queries for host addresses from hosts on the -same network as the server will receive responses with local network -addresses listed first, then addresses on the sort list, then other -addresses. -.LP -The ``xfrnets'' directive (not shown) can be used to implement primitive -access control. If this directive is given, then your name server will -only answer zone transfer requests from hosts which are on networks listed -in your ``xfrnets'' directives. This directive may also be given as -``tcplist'' for compatibility with older, interim servers. -.LP -The ``include'' directive (not shown) can be used to process the contents -of some other file as though they appeared in place of the ``include'' -directive. This is useful if you have a lot of zones or if you have -logical groupings of zones which are maintained by different people. -The ``include'' directive takes one argument, that being the name of the -file whose contents are to be included. No quotes are necessary around -the file name. -.LP -The ``bogusns'' directive (not shown) tells \s-1BIND\s+1 that no queries -are to be sent to the specified name server addresses (which are specified -as dotted quads, not as domain names). This is useful when you know that -some popular server has bad data in a zone or cache, and you want to avoid -contamination while the problem is being fixed. -.LP -The ``limit'' directive can be used to change \s-1BIND\s+1's internal limits, -some of which (\fBdatasize\fP, for example) are implemented by the system and -others (like \fBtransfers-in\fP) by \s-1BIND\s+1 itself. The number following -the limit name can be scaled by postfixing a ``k,'' ``m,'' or ``g'' for -kilobytes, megabytes, and gigabytes respectively. -\fBdatasize\fP's argument sets the process data size enforced by the kernel. -\fINote:\fP not all systems provide a call to implement this -- on such -systems, the use of the \fBdatasize\fP parameter of ``limit'' will result in -a warning message. -\fBtransfers-in\fP's argument is the number of \fInamed-xfer\fP subprocesses -which \s-1BIND\s+1 will spawn at any one time. -\fBtransfers-per-ns\fP's argument is the maximum number of zone transfers to -be simultaneously initiated to any given remote name server. -\fBfiles\fP's argument sets the number of file descriptors available to -the process. \fINote:\fP not all systems provide a call to implement -this -- on such systems, the use of the \fBfiles\fP parameter of ``limit'' -will result in a warning message. -.LP -The ``options'' directive introduces a boolean specifier that changes the -behaviour of \s-1BIND\s+1. More than one option can be specified in a single -directive. The currently defined options are as follows: -\fBno-recursion\fP, which will cause \s-1BIND\s+1 to answer with a referral -rather than actual data whenever it receives a query for a name it is not -authoritative for -- don't set this on a server that is listed in any host's -\fIresolv.conf\fP file; -\fBno-fetch-glue\fP, which keeps \s-1BIND\s+1 from fetching missing glue when -constructing the ``additional data'' section of a response; this can be used -in conjunction with \fBno-recursion\fP to prevent \s-1BIND\s+1's cache from -ever growing in size or becoming corrupted; -\fBquery-log\fP, which causes all queries to be logged via -syslog(@SYS_OPS_EXT@) -- this is a lot of data, don't turn it on lightly; -\fBforward-only\fP, which causes the server to query only its forwarders -- -this option is normally used on machine that wishes to run a server but for -physical or administrative reasons cannot be given access to the Internet; -and \fBfake-iquery\fP, which tells \s-1BIND\s+1 to send back a useless and -bogus reply to ``inverse queries'' rather than responding with an error -- -this is helpful if you have a lot of microcomputers or SunOS hosts or both. -.LP -The ``check-names'' directive tells \s-1BIND\s+1 to check names in either -``primary'' or ``secondary'' zone files, or in messages (``response'') -received during recursion (for example, those which would be forwarded back -to a firewalled requestor). For each type of name, -\s-1BIND\s+1 can be told to ``fail'', such that a zone would not be loaded -or a response would not be cached or forwarded, or merely ``warn'' which -would cause a message to be emitted in the system operations logs, or to -``ignore'' the badness of a name and process it in the traditional fashion. -Names are considered good if they match RFC 952's expectations (if they are -host names), or if they consist only of printable \s-1ASCII\s+1 characters -(if they are not host names). -.LP -The ``max-fetch'' directive (not shown) is allowed for backward compatibility; -its meaning is identical to ``limit transfers-in''. -.PP -The master file consists of control information and a list of resource -records for objects in the zone of the forms: -.RS -.nf - -$INCLUDE <filename> <opt_domain> -$ORIGIN <domain> -<domain> <opt_ttl> <opt_class> <type> <resource_record_data> - -.fi -.RE -where -.I domain -is "." for root, "@" for the current origin, or a standard domain -name. If -.I domain -is a standard domain name that does not end with ``.'', the current origin -is appended to the domain. Domain names ending with ``.'' are -unmodified. -The -.I opt_domain -field is used to define an origin for the data in an included file. -It is equivalent to placing a $ORIGIN statement before the first -line of the included file. The field is optional. -Neither the -.I opt_domain -field nor $ORIGIN statements in the included file modify the current origin -for this file. -The -.I opt_ttl -field is an optional integer number for the time-to-live field. -It defaults to zero, meaning the minimum value specified in the SOA -record for the zone. -The -.I opt_class -field is the object address type; currently only one type is supported, -.BR IN , -for objects connected to the DARPA Internet. -The -.I type -field contains one of the following tokens; the data expected in the -.I resource_record_data -field is in parentheses. -.TP "\w'MINFO 'u" -A -a host address (dotted quad) -.IP NS -an authoritative name server (domain) -.IP MX -a mail exchanger (domain), preceded by a preference value (0..32767), -with lower numeric values representing higher logical preferences. -.IP CNAME -the canonical name for an alias (domain) -.IP SOA -marks the start of a zone of authority (domain of originating host, -domain address of maintainer, a serial number and the following -parameters in seconds: refresh, retry, expire and minimum TTL (see RFC 883)). -.IP NULL -a null resource record (no format or data) -.IP RP -a Responsible Person for some domain name (mailbox, TXT-referral) -.IP PTR -a domain name pointer (domain) -.IP HINFO -host information (cpu_type OS_type) -.PP -Resource records normally end at the end of a line, -but may be continued across lines between opening and closing parentheses. -Comments are introduced by semicolons and continue to the end of the line. -.PP -Note that there are other resource record types, not shown here. You should -consult the \s-1BIND\s+1 Operations Guide (``\s-1BOG\s+1'') for the complete -list. Some resource record types may have been standardized in newer RFC's -but not yet implemented in this version of \s-1BIND\s+1. -.PP -Each master zone file should begin with an SOA record for the zone. -An example SOA record is as follows: -.LP -.nf -@ IN SOA ucbvax.Berkeley.EDU. rwh.ucbvax.Berkeley.EDU. ( -.ta \w'x\ IN\ SOA\ 'u +\w'1989020501\ 'u - 1989020501 ; serial - 10800 ; refresh - 3600 ; retry - 3600000 ; expire - 86400 ) ; minimum -.fi -.LP -The SOA specifies a serial number, which should be changed each time the -master file is changed. Note that the serial number can be given as a -dotted number, but this is a \fIvery\fP unwise thing to do since the -translation to normal integers is via concatenation rather than -multiplication and addition. You can spell out the year, month, day of -month, and 0..99 version number and still fit inside the unsigned 32-bit -size of this field. It's true that we will have to rethink this strategy in -the year 4294 (Greg.) but we're not worried about it. Secondary servers -check the serial number at intervals specified by the refresh time in -seconds; if the serial number changes, a zone transfer will be done to load -the new data. If a master server cannot be contacted when a refresh is due, -the retry time specifies the interval at which refreshes should be attempted. -If a master server cannot be contacted within the interval given by the -expire time, all data from the zone is discarded by secondary servers. The -minimum value is the time-to-live (``\s-1TTL\s+1'') used by records in the -file with no explicit time-to-live value. -.SH NOTES -The boot file directives ``domain'' and ``suffixes'' have been -obsoleted by a more useful resolver-based implementation of -suffixing for partially qualified domain names. The prior mechanisms -could fail under a number of situations, especially when then local -nameserver did not have complete information. -.sp -The following signals have the specified effect when sent to the -server process using the -.IR kill (@CMD_EXT@) -command. -.IP SIGHUP -Causes server to read named.boot and reload the database. If the server -is built with the FORCED_RELOAD compile-time option, then SIGHUP will -also cause the server to check the serial number on all secondary zones. -Normally the serial numbers are only checked at the SOA-specified intervals. -.IP SIGINT -Dumps the current data base and cache to /var/tmp/named_dump.db -.IP SIGIOT -Dumps statistics data into /var/tmp/named.stats if the server is -compiled with -DSTATS. Statistics data is appended to the file. Some -systems use SIGABRT rather than SIGIOT for this. -.IP SIGSYS -Dumps the profiling data in /var/tmp if the server is compiled -with profiling (server forks, chdirs and exits). -.IP SIGTERM -Dumps the primary and secondary database files. -Used to save modified data on shutdown if the -server is compiled with dynamic updating enabled. -.IP SIGUSR1 -Turns on debugging; each SIGUSR1 increments debug level. -(SIGEMT on older systems without SIGUSR1) -.IP SIGUSR2 -Turns off debugging completely. -(SIGFPE on older systems without SIGUSR2) -.IP SIGWINCH -Toggles logging of all incoming queries via syslog(@SYS_OPS_EXT@) -(requires server to have been built with the QRYLOG option). -.SH FILES -.nf -.ta \w'/var/tmp/named_dump.db 'u -/etc/named.boot name server configuration boot file -/etc/named.pid the process id (on older systems) -/var/run/named.pid the process id (on newer systems) -/var/tmp/named_dump.db dump of the name server database -/var/tmp/named.run debug output -/var/tmp/named.stats nameserver statistics data -.fi -.SH "SEE ALSO" -kill(@CMD_EXT@), gethostbyname(@LIB_NETWORK_EXT@), signal(@SYSCALL_EXT@), -resolver(@LIB_NETWORK_EXT@), resolver(@FORMAT_EXT@), hostname(@DESC_EXT@), -RFC 882, RFC 883, RFC 973, RFC 974, RFC 1033, RFC 1034, RFC 1035, RFC 1123, -\fIName Server Operations Guide for \s-1BIND\s+1\fR diff --git a/contrib/bind/man/named.reload.8 b/contrib/bind/man/named.reload.8 deleted file mode 100644 index b838ea04b339..000000000000 --- a/contrib/bind/man/named.reload.8 +++ /dev/null @@ -1,69 +0,0 @@ -.\" ++Copyright++ 1987, 1993 -.\" - -.\" Copyright (c) 1987, 1993 -.\" The Regents of the University of California.

Up to 10 pairs may -be specified. -.IP -e.g. sortlist 130.155.160.0/255.255.240.0 130.155.0.0 -.TP -\fBoptions\fP -Options allows certain internal resolver variables to be modified. -The syntax is -.IP -\fBoptions\fP \fIoption\fP \fI...\fP -.IP -where \fIoption\fP is one of the following: -.IP -\fBdebug\fP \(em sets RES_DEBUG in _res.options. -.IP -\fBndots:\fP\fIn\fP \(em sets a threshold for the number of dots which -must appear in a name given to \fBres_query\fP (see \fIresolver\fP(@LIB_NETWORK_EXT@)) -before an \fIinitial absolute query\fP will be made. The default for -\fIn\fP is ``1'', meaning that if there are any dots in a name, the name -will be tried first as an absolute name before any \fIsearch list\fP -elements are appended to it. -.LP -The \fIdomain\fP and \fIsearch\fP keywords are mutually exclusive. -If more than one instance of these keywords is present, -the last instance wins. -.LP -The \fIsearch\fP keyword of a system's \fIresolv.conf\fP file can be -overridden on a per-process basis by setting the environment variable -``\s-1LOCALDOMAIN\s+1'' to a space-separated list of search domains. -.LP -The \fIoptions\fP keyword of a system's \fIresolv.conf\fP file can be -amended on a per-process basis by setting the environment variable -``\s-1RES_OPTIONS\s+1'' to a space-separated list of resolver options -as explained above under \fBoptions\fP. -.LP -The keyword and value must appear on a single line, and the keyword -(e.g. \fBnameserver\fP) must start the line.

Each node -of the tree contains the expected left & right subtree pointers, a short int -balance indicator, and a pointer to the user data. On a 32 bit system, this -means an overhead of 4+4+2+4 bytes per node (or, on a RISC or otherwise -alignment constrained system with implied padding, 4+4+4+4 bytes per node). -There is no key data type enforced by this package; a caller supplied -compare routine is used to compare user data blocks. -.PP -Balanced binary trees are very fast on searches and replacements, but have a -moderately high cost for additions and deletions. If your application does a -lot more searches and replacements than it does additions and deletions, the -balanced (AVL) binary tree is a good choice for a data structure. -.PP -.I Tree_init -creates an empty tree and binds it to -.I tree -(which for this and all other routines in this package should be declared as -a pointer to void or int, and passed by reference), which can then be used by -other routines in this package. Note that more than one -.I tree -variable can exist at once; thus multiple trees can be manipulated -simultaneously. -.PP -.I Tree_srch -searches a tree for a specific node and returns either -.I NULL -if no node was found, or the value of the user data pointer if the node -was found. -.I compare -is the address of a function to compare two user data blocks. This routine -should work much the way -.IR strcmp (3) -does; in fact, -.I strcmp -could be used if the user data was a \s-2NUL\s+2 terminated string. -.I data -is the address of a user data block to be used by -.I compare -as the search criteria. The tree is searched for a node where -.I compare -returns 0. -.PP -.I Tree_add -inserts or replaces a node in the specified tree. The tree specified by -.I tree -is searched as in -.I tree_srch, -and if a node is found to match -.I data, -then the -.I del_uar -function, if non\-\s-2NULL\s+2, is called with the address of the user data -block for the node (this routine should deallocate any dynamic memory which -is referenced exclusively by the node); the user data pointer for the node -is then replaced by the value of -.I data. -If no node is found to match, a new node is added (which may or may not -cause a transparent rebalance operation), with a user data pointer equal to -.I data. -A rebalance may or may not occur, depending on where the node is added -and what the rest of the tree looks like. -.I Tree_add -will return the -.I data -pointer unless catastrophe occurs in which case it will return \s-2NULL\s+2. -.PP -.I Tree_delete -deletes a node from -.I tree. -A rebalance may or may not occur, depending on where the node is removed from -and what the rest of the tree looks like. -.I Tree_delete -returns TRUE if a node was deleted, FALSE otherwise. -.PP -.I Tree_trav -traverses all of -.I tree, -calling -.I trav_uar -with the address of each user data block. If -.I trav_uar -returns FALSE at any time, -.I tree_trav -will immediately return FALSE to its caller. Otherwise all nodes will be -reached and -.I tree_trav -will return TRUE. -.PP -.I Tree_mung -deletes every node in -.I tree, -calling -.I del_uar -(if it is not \s-2NULL\s+2) with the user data address from each node (see -.I tree_add -and -.I tree_delete -above). The tree is left in the same state that -.I tree_init -leaves it in \- i.e., empty. -.SH BUGS -Should have a way for the caller to specify application specific -.I malloc -and -.I free -functions to be used internally when allocating meta data. -.SH AUTHOR -Paul Vixie, converted and augumented from Modula\-2 examples in -.I Algorithms & Data Structures, -Niklaus Wirth, Prentice\-Hall, ISBN 0\-13\-022005\-1. diff --git a/contrib/bind/res/Makefile b/contrib/bind/res/Makefile deleted file mode 100644 index 834d74a9c31d..000000000000 --- a/contrib/bind/res/Makefile +++ /dev/null @@ -1,114 +0,0 @@ -# -# from @(#)Makefile 5.16 (Berkeley) 3/14/88 -# $Id: Makefile,v 8.14 1997/06/01 20:34:37 vixie Exp $ -# - -## ++Copyright++ 1988, 1995 -## - -## Copyright (c) 1988, 1995 -## The Regents of the University of California.

dig now links against - * some of nslookup's .o files rather than #including them or maintaining - * local copies of them. in some sense, dig belongs in the nslookup - * subdirectory rather than up here in "tools", but that's for arc@sgi.com - * (owner of nslookup) to decide. - * - * while merging dig back into the BIND release, i made a number of - * structural changes. for one thing, i put all of dig's private - * library routines into this file rather than maintaining them in - * separate, #included, files. i don't like to #include ".c" files. - * i removed all calls to "bcopy", replacing them with structure - * assignments. i removed all "extern"'s of standard functions, - * replacing them with #include's of standard header files. this - * version of dig is probably as portable as the rest of BIND. - * - * i had to remove the query-time and packet-count statistics since - * the current libresolv.a is a lot harder to modify to maintain these - * than the 4.8 one (used in the original dig) was. for consolation, - * i added a "usage" message with extensive help text. - * - * to save my (limited, albeit) sanity, i ran "indent" over the source. - * i also added the standard berkeley/DEC copyrights, since this file now - * contains a fair amount of non-USC code. note that the berkeley and - * DEC copyrights do not prohibit redistribution, with or without fee; - * we add them only to protect ourselves (you have to claim copyright - * in order to disclaim liability and warranty). - * - * Paul Vixie, Palo Alto, CA, April 1993 - **************************************************************************** - - /******************************************************************* - ** DiG -- Domain Information Groper ** - ** ** - ** dig.c - Version 2.1 (7/12/94) ("BIND takeover") ** - ** ** - ** Developed by: Steve Hotz & Paul Mockapetris ** - ** USC Information Sciences Institute (USC-ISI) ** - ** Marina del Rey, California ** - ** 1989 ** - ** ** - ** dig.c - ** - ** Version 2.0 (9/1/90) ** - ** o renamed difftime() difftv() to avoid ** - ** clash with ANSI C ** - ** o fixed incorrect # args to strcmp,gettimeofday ** - ** o incorrect length specified to strncmp ** - ** o fixed broken -sticky -envsa -envset functions ** - ** o print options/flags redefined & modified ** - ** ** - ** Version 2.0.beta (5/9/90) ** - ** o output format - helpful to `doc` ** - ** o minor cleanup ** - ** o release to beta testers ** - ** ** - ** Version 1.1.beta (10/26/89) ** - ** o hanging zone transer (when REFUSED) fixed ** - ** o trailing dot added to domain names in RDATA ** - ** o ISI internal ** - ** ** - ** Version 1.0.tmp (8/27/89) ** - ** o Error in prnttime() fixed ** - ** o no longer dumps core on large pkts ** - ** o zone transfer (axfr) added ** - ** o -x added for inverse queries ** - ** (i.e. "dig -x 128.9.0.32") ** - ** o give address of default server ** - ** o accept broadcast to server @255.255.255.255 ** - ** ** - ** Version 1.0 (3/27/89) ** - ** o original release ** - ** ** - ** DiG is Public Domain, and may be used for any purpose as ** - ** long as this notice is not removed. ** - **** **** - **** NOTE: Version 2.0.beta is not for public distribution **** - **** **** - *******************************************************************/ - - -#define VERSION 22 -#define VSTRING "2.2" - -#include <sys/types.h> -#include <sys/param.h> -#include <sys/file.h> -#include <sys/stat.h> -#include <sys/socket.h> -#include <sys/time.h> - -#include <netinet/in.h> -#include <arpa/inet.h> -#include <arpa/nameser.h> - -#include <netdb.h> -#include <stdio.h> -#include <resolv.h> -#include <ctype.h> -#include <errno.h> -#include <string.h> -#include <setjmp.h> -#include <fcntl.h> - -#include "nslookup/res.h" -#include "../conf/portability.h" - -#define PRF_DEF 0x2ff9 -#define PRF_MIN 0xA930 -#define PRF_ZONE 0x24f9 - -#ifndef MAXHOSTNAMELEN -#define MAXHOSTNAMELEN 256 -#endif - -int eecode = 0;
