IP addresses will not -be checked to ensure they match. -.It Fl -no-gss-delegate -Disable delegation of GSSAPI credentials. -.It Fl l -Disables command line editing. -.It Fl x -Encrypt command and data channel. -.El -.Pp -The client host with which -.Nm ftp -is to communicate may be specified on the command line. -If this is done, -.Nm ftp -will immediately attempt to establish a connection to an -.Tn FTP -server on that host; otherwise, -.Nm ftp -will enter its command interpreter and await instructions -from the user. -When -.Nm ftp -is awaiting commands from the user the prompt -.Ql ftp\*[Gt] -is provided to the user. -The following commands are recognized -by -.Nm ftp : -.Bl -tag -width Fl -.It Ic \&! Op Ar command Op Ar args -Invoke an interactive shell on the local machine. -If there are arguments, the first is taken to be a command to execute -directly, with the rest of the arguments as its arguments. -.It Ic \&$ Ar macro-name Op Ar args -Execute the macro -.Ar macro-name -that was defined with the -.Ic macdef -command. -Arguments are passed to the macro unglobbed. -.It Ic account Op Ar passwd -Supply a supplemental password required by a remote system for access -to resources once a login has been successfully completed. -If no argument is included, the user will be prompted for an account -password in a non-echoing input mode. -.It Ic append Ar local-file Op Ar remote-file -Append a local file to a file on the remote machine. -If -.Ar remote-file -is left unspecified, the local file name is used in naming the -remote file after being altered by any -.Ic ntrans -or -.Ic nmap -setting. -File transfer uses the current settings for -.Ic type , -.Ic format , -.Ic mode , -and -.Ic structure . -.It Ic ascii -Set the file transfer -.Ic type -to network -.Tn ASCII . -This is the default type. -.It Ic bell -Arrange that a bell be sounded after each file transfer -command is completed. -.It Ic binary -Set the file transfer -.Ic type -to support binary image transfer. -.It Ic bye -Terminate the -.Tn FTP -session with the remote server -and exit -.Nm ftp . -An end of file will also terminate the session and exit. -.It Ic case -Toggle remote computer file name case mapping during -.Ic mget -commands. -When -.Ic case -is on (default is off), remote computer file names with all letters in -upper case are written in the local directory with the letters mapped -to lower case. -.It Ic \&cd Ar remote-directory -Change the working directory on the remote machine -to -.Ar remote-directory . -.It Ic cdup -Change the remote machine working directory to the parent of the -current remote machine working directory. -.It Ic chmod Ar mode file-name -Change the permission modes of the file -.Ar file-name -on the remote -sytem to -.Ar mode . -.It Ic close -Terminate the -.Tn FTP -session with the remote server, and -return to the command interpreter. -Any defined macros are erased. -.It Ic \&cr -Toggle carriage return stripping during -ascii type file retrieval. -Records are denoted by a carriage return/linefeed sequence -during ascii type file transfer. -When -.Ic \&cr -is on (the default), carriage returns are stripped from this -sequence to conform with the -.Ux -single linefeed record -delimiter. -Records on -.Pf non\- Ns Ux -remote systems may contain single linefeeds; -when an ascii type transfer is made, these linefeeds may be -distinguished from a record delimiter only when -.Ic \&cr -is off. -.It Ic delete Ar remote-file -Delete the file -.Ar remote-file -on the remote machine. -.It Ic debug Op Ar debug-value -Toggle debugging mode. -If an optional -.Ar debug-value -is specified it is used to set the debugging level. -When debugging is on, -.Nm ftp -prints each command sent to the remote machine, preceded -by the string -.Ql \-\-\*[Gt] -.It Xo -.Ic dir -.Op Ar remote-directory -.Op Ar local-file -.Xc -Print a listing of the directory contents in the -directory, -.Ar remote-directory , -and, optionally, placing the output in -.Ar local-file . -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic dir -output. -If no directory is specified, the current working -directory on the remote machine is used. -If no local -file is specified, or -.Ar local-file -is -.Fl , -output comes to the terminal. -.It Ic disconnect -A synonym for -.Ar close . -.It Ic form Ar format -Set the file transfer -.Ic form -to -.Ar format . -The default format is \*(Lqfile\*(Rq. -.It Ic get Ar remote-file Op Ar local-file -Retrieve the -.Ar remote-file -and store it on the local machine. -If the local -file name is not specified, it is given the same -name it has on the remote machine, subject to -alteration by the current -.Ic case , -.Ic ntrans , -and -.Ic nmap -settings. -The current settings for -.Ic type , -.Ic form , -.Ic mode , -and -.Ic structure -are used while transferring the file. -.It Ic glob -Toggle filename expansion for -.Ic mdelete , -.Ic mget -and -.Ic mput . -If globbing is turned off with -.Ic glob , -the file name arguments -are taken literally and not expanded. -Globbing for -.Ic mput -is done as in -.Xr csh 1 . -For -.Ic mdelete -and -.Ic mget , -each remote file name is expanded -separately on the remote machine and the lists are not merged. -Expansion of a directory name is likely to be -different from expansion of the name of an ordinary file: -the exact result depends on the foreign operating system and ftp server, -and can be previewed by doing -.Ql mls remote-files \- . -As a security measure, remotely globbed files that starts with -.Sq / -or contains -.Sq ../ , -will not be automatically received.

-a null line (consecutive newline characters -in a file or -carriage returns from the terminal) terminates macro input mode. -There is a limit of 16 macros and 4096 total characters in all -defined macros. -Macros remain defined until a -.Ic close -command is executed. -The macro processor interprets `$' and `\e' as special characters. -A `$' followed by a number (or numbers) is replaced by the -corresponding argument on the macro invocation command line. -A `$' followed by an `i' signals that macro processor that the -executing macro is to be looped. -On the first pass `$i' is -replaced by the first argument on the macro invocation command line, -on the second pass it is replaced by the second argument, and so on. -A `\e' followed by any character is replaced by that character. -Use the `\e' to prevent special treatment of the `$'. -.It Ic mdelete Op Ar remote-files -Delete the -.Ar remote-files -on the remote machine. -.It Ic mdir Ar remote-files local-file -Like -.Ic dir , -except multiple remote files may be specified. -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic mdir -output. -.It Ic mget Ar remote-files -Expand the -.Ar remote-files -on the remote machine -and do a -.Ic get -for each file name thus produced. -See -.Ic glob -for details on the filename expansion. -Resulting file names will then be processed according to -.Ic case , -.Ic ntrans , -and -.Ic nmap -settings. -Files are transferred into the local working directory, -which can be changed with -.Ql lcd directory ; -new local directories can be created with -.Ql "\&! mkdir directory" . -.It Ic mkdir Ar directory-name -Make a directory on the remote machine. -.It Ic mls Ar remote-files local-file -Like -.Ic nlist , -except multiple remote files may be specified, -and the -.Ar local-file -must be specified. -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic mls -output. -.It Ic mode Op Ar mode-name -Set the file transfer -.Ic mode -to -.Ar mode-name . -The default mode is \*(Lqstream\*(Rq mode. -.It Ic modtime Ar file-name -Show the last modification time of the file on the remote machine. -.It Ic mput Ar local-files -Expand wild cards in the list of local files given as arguments -and do a -.Ic put -for each file in the resulting list. -See -.Ic glob -for details of filename expansion. -Resulting file names will then be processed according to -.Ic ntrans -and -.Ic nmap -settings. -.It Ic newer Ar file-name -Get the file only if the modification time of the remote file is more -recent that the file on the current system. -If the file does not -exist on the current system, the remote file is considered -.Ic newer . -Otherwise, this command is identical to -.Ar get . -.It Xo -.Ic nlist -.Op Ar remote-directory -.Op Ar local-file -.Xc -Print a list of the files in a -directory on the remote machine. -If -.Ar remote-directory -is left unspecified, the current working directory is used. -If interactive prompting is on, -.Nm ftp -will prompt the user to verify that the last argument is indeed the -target local file for receiving -.Ic nlist -output. -If no local file is specified, or if -.Ar local-file -is -.Fl , -the output is sent to the terminal. -.It Ic nmap Op Ar inpattern outpattern -Set or unset the filename mapping mechanism. -If no arguments are specified, the filename mapping mechanism is unset. -If arguments are specified, remote filenames are mapped during -.Ic mput -commands and -.Ic put -commands issued without a specified remote target filename. -If arguments are specified, local filenames are mapped during -.Ic mget -commands and -.Ic get -commands issued without a specified local target filename. -This command is useful when connecting to a -.No non\- Ns Ux -remote computer -with different file naming conventions or practices. -The mapping follows the pattern set by -.Ar inpattern -and -.Ar outpattern . -.Op Ar Inpattern -is a template for incoming filenames (which may have already been -processed according to the -.Ic ntrans -and -.Ic case -settings). -Variable templating is accomplished by including the -sequences `$1', `$2', ..., `$9' in -.Ar inpattern . -Use `\\' to prevent this special treatment of the `$' character. -All other characters are treated literally, and are used to determine the -.Ic nmap -.Op Ar inpattern -variable values. -For example, given -.Ar inpattern -$1.$2 and the remote file name "mydata.data", $1 would have the value -"mydata", and $2 would have the value "data". -The -.Ar outpattern -determines the resulting mapped filename. -The sequences `$1', `$2', ...., `$9' are replaced by any value resulting -from the -.Ar inpattern -template. -The sequence `$0' is replace by the original filename. -Additionally, the sequence -.Ql Op Ar seq1 , Ar seq2 -is replaced by -.Op Ar seq1 -if -.Ar seq1 -is not a null string; otherwise it is replaced by -.Ar seq2 . -For example, the command -.Pp -.Bd -literal -offset indent -compact -nmap $1.$2.$3 [$1,$2].[$2,file] -.Ed -.Pp -would yield -the output filename "myfile.data" for input filenames "myfile.data" and -"myfile.data.old", "myfile.file" for the input filename "myfile", and -"myfile.myfile" for the input filename ".myfile". -Spaces may be included in -.Ar outpattern , -as in the example: `nmap $1 sed "s/ *$//" \*[Gt] $1' . -Use the `\e' character to prevent special treatment -of the `$','[','[', and `,' characters. -.It Ic ntrans Op Ar inchars Op Ar outchars -Set or unset the filename character translation mechanism. -If no arguments are specified, the filename character -translation mechanism is unset. -If arguments are specified, characters in -remote filenames are translated during -.Ic mput -commands and -.Ic put -commands issued without a specified remote target filename. -If arguments are specified, characters in -local filenames are translated during -.Ic mget -commands and -.Ic get -commands issued without a specified local target filename. -This command is useful when connecting to a -.No non\- Ns Ux -remote computer -with different file naming conventions or practices. -Characters in a filename matching a character in -.Ar inchars -are replaced with the corresponding character in -.Ar outchars . -If the character's position in -.Ar inchars -is longer than the length of -.Ar outchars , -the character is deleted from the file name. -.It Ic open Ar host Op Ar port -Establish a connection to the specified -.Ar host -.Tn FTP -server. -An optional port number may be supplied, -in which case, -.Nm ftp -will attempt to contact an -.Tn FTP -server at that port. -If the -.Ic auto-login -option is on (default), -.Nm ftp -will also attempt to automatically log the user in to -the -.Tn FTP -server (see below). -.It Ic passive -Toggle passive mode. If passive mode is turned on -(default is off), the ftp client will -send a -.Dv PASV -command for all data connections instead of the usual -.Dv PORT -command. The -.Dv PASV -command requests that the remote server open a port for the data connection -and return the address of that port. The remote server listens on that -port and the client connects to it. When using the more traditional -.Dv PORT -command, the client listens on a port and sends that address to the remote -server, who connects back to it. Passive mode is useful when using -.Nm ftp -through a gateway router or host that controls the directionality of -traffic. -(Note that though ftp servers are required to support the -.Dv PASV -command by RFC 1123, some do not.) -.It Ic prompt -Toggle interactive prompting. -Interactive prompting -occurs during multiple file transfers to allow the -user to selectively retrieve or store files. -If prompting is turned off (default is on), any -.Ic mget -or -.Ic mput -will transfer all files, and any -.Ic mdelete -will delete all files. -.It Ic proxy Ar ftp-command -Execute an ftp command on a secondary control connection. -This command allows simultaneous connection to two remote ftp -servers for transferring files between the two servers. -The first -.Ic proxy -command should be an -.Ic open , -to establish the secondary control connection. -Enter the command "proxy ?" to see other ftp commands executable on the -secondary connection. -The following commands behave differently when prefaced by -.Ic proxy : -.Ic open -will not define new macros during the auto-login process, -.Ic close -will not erase existing macro definitions, -.Ic get -and -.Ic mget -transfer files from the host on the primary control connection -to the host on the secondary control connection, and -.Ic put , -.Ic mput , -and -.Ic append -transfer files from the host on the secondary control connection -to the host on the primary control connection. -Third party file transfers depend upon support of the ftp protocol -.Dv PASV -command by the server on the secondary control connection. -.It Ic put Ar local-file Op Ar remote-file -Store a local file on the remote machine. -If -.Ar remote-file -is left unspecified, the local file name is used -after processing according to any -.Ic ntrans -or -.Ic nmap -settings -in naming the remote file. -File transfer uses the -current settings for -.Ic type , -.Ic format , -.Ic mode , -and -.Ic structure . -.It Ic pwd -Print the name of the current working directory on the remote -machine. -.It Ic quit -A synonym for -.Ic bye . -.It Ic quote Ar arg1 arg2 ... -The arguments specified are sent, verbatim, to the remote -.Tn FTP -server. -.It Ic recv Ar remote-file Op Ar local-file -A synonym for get. -.It Ic reget Ar remote-file Op Ar local-file -Reget acts like get, except that if -.Ar local-file -exists and is -smaller than -.Ar remote-file , -.Ar local-file -is presumed to be -a partially transferred copy of -.Ar remote-file -and the transfer -is continued from the apparent point of failure. -This command -is useful when transferring very large files over networks that -are prone to dropping connections. -.It Ic remotehelp Op Ar command-name -Request help from the remote -.Tn FTP -server. -If a -.Ar command-name -is specified it is supplied to the server as well. -.It Ic remotestatus Op Ar file-name -With no arguments, show status of remote machine. -If -.Ar file-name -is specified, show status of -.Ar file-name -on remote machine. -.It Xo -.Ic rename -.Op Ar from -.Op Ar to -.Xc -Rename the file -.Ar from -on the remote machine, to the file -.Ar to . -.It Ic reset -Clear reply queue. -This command re-synchronizes command/reply sequencing with the remote -ftp server. -Resynchronization may be necessary following a violation of the ftp protocol -by the remote server. -.It Ic restart Ar marker -Restart the immediately following -.Ic get -or -.Ic put -at the -indicated -.Ar marker . -On -.Ux -systems, marker is usually a byte -offset into the file. -.It Ic rmdir Ar directory-name -Delete a directory on the remote machine. -.It Ic runique -Toggle storing of files on the local system with unique filenames. -If a file already exists with a name equal to the target -local filename for a -.Ic get -or -.Ic mget -command, a ".1" is appended to the name. -If the resulting name matches another existing file, -a ".2" is appended to the original name. -If this process continues up to ".99", an error -message is printed, and the transfer does not take place. -The generated unique filename will be reported. -Note that -.Ic runique -will not affect local files generated from a shell command -(see below). -The default value is off. -.It Ic send Ar local-file Op Ar remote-file -A synonym for put. -.It Ic sendport -Toggle the use of -.Dv PORT -commands. -By default, -.Nm ftp -will attempt to use a -.Dv PORT -command when establishing -a connection for each data transfer. -The use of -.Dv PORT -commands can prevent delays -when performing multiple file transfers. -If the -.Dv PORT -command fails, -.Nm ftp -will use the default data port. -When the use of -.Dv PORT -commands is disabled, no attempt will be made to use -.Dv PORT -commands for each data transfer. -This is useful -for certain -.Tn FTP -implementations which do ignore -.Dv PORT -commands but, incorrectly, indicate they've been accepted. -.It Ic site Ar arg1 arg2 ... -The arguments specified are sent, verbatim, to the remote -.Tn FTP -server as a -.Dv SITE -command. -.It Ic size Ar file-name -Return size of -.Ar file-name -on remote machine. -.It Ic status -Show the current status of -.Nm ftp . -.It Ic struct Op Ar struct-name -Set the file transfer -.Ar structure -to -.Ar struct-name . -By default \*(Lqstream\*(Rq structure is used. -.It Ic sunique -Toggle storing of files on remote machine under unique file names. -Remote ftp server must support ftp protocol -.Dv STOU -command for -successful completion. -The remote server will report unique name. -Default value is off. -.It Ic system -Show the type of operating system running on the remote machine. -.It Ic tenex -Set the file transfer type to that needed to -talk to -.Tn TENEX -machines. -.It Ic trace -Toggle packet tracing. -.It Ic type Op Ar type-name -Set the file transfer -.Ic type -to -.Ar type-name . -If no type is specified, the current type -is printed. -The default type is network -.Tn ASCII . -.It Ic umask Op Ar newmask -Set the default umask on the remote server to -.Ar newmask . -If -.Ar newmask -is omitted, the current umask is printed. -.It Xo -.Ic user Ar user-name -.Op Ar password -.Op Ar account -.Xc -Identify yourself to the remote -.Tn FTP -server. -If the -.Ar password -is not specified and the server requires it, -.Nm ftp -will prompt the user for it (after disabling local echo). -If an -.Ar account -field is not specified, and the -.Tn FTP -server -requires it, the user will be prompted for it. -If an -.Ar account -field is specified, an account command will -be relayed to the remote server after the login sequence -is completed if the remote server did not require it -for logging in. -Unless -.Nm ftp -is invoked with \*(Lqauto-login\*(Rq disabled, this -process is done automatically on initial connection to -the -.Tn FTP -server. -.It Ic verbose -Toggle verbose mode. -In verbose mode, all responses from -the -.Tn FTP -server are displayed to the user. -In addition, -if verbose is on, when a file transfer completes, statistics -regarding the efficiency of the transfer are reported. -By default, -verbose is on. -.It Ic \&? Op Ar command -A synonym for help. -.El -.Pp -The following command can be used with ftpsec-aware servers. -.Bl -tag -width Fl -.It Xo -.Ic prot -.Ar clear | -.Ar safe | -.Ar confidential | -.Ar private -.Xc -Set the data protection level to the requested level. -.El -.Pp -The following command can be used with ftp servers that has -implemented the KAUTH site command. -.Bl -tag -width Fl -.It Ic kauth Op Ar principal -Obtain remote tickets. -.El -.Pp -Command arguments which have embedded spaces may be quoted with -quote `"' marks. -.Sh ABORTING A FILE TRANSFER -To abort a file transfer, use the terminal interrupt key -(usually Ctrl-C). -Sending transfers will be immediately halted. -Receiving transfers will be halted by sending a ftp protocol -.Dv ABOR -command to the remote server, and discarding any further data received. -The speed at which this is accomplished depends upon the remote -server's support for -.Dv ABOR -processing. -If the remote server does not support the -.Dv ABOR -command, an -.Ql ftp\*[Gt] -prompt will not appear until the remote server has completed -sending the requested file. -.Pp -The terminal interrupt key sequence will be ignored when -.Nm ftp -has completed any local processing and is awaiting a reply -from the remote server. -A long delay in this mode may result from the ABOR processing described -above, or from unexpected behavior by the remote server, including -violations of the ftp protocol. -If the delay results from unexpected remote server behavior, the local -.Nm ftp -program must be killed by hand. -.Sh FILE NAMING CONVENTIONS -Files specified as arguments to -.Nm ftp -commands are processed according to the following rules. -.Bl -enum -.It -If the file name -.Sq Fl -is specified, the -.Ar stdin -(for reading) or -.Ar stdout -(for writing) is used. -.It -If the first character of the file name is -.Sq \&| , -the -remainder of the argument is interpreted as a shell command. -.Nm Ftp -then forks a shell, using -.Xr popen 3 -with the argument supplied, and reads (writes) from the stdout -(stdin). -If the shell command includes spaces, the argument -must be quoted; e.g. -\*(Lq" ls -lt"\*(Rq. -A particularly -useful example of this mechanism is: \*(Lqdir more\*(Rq. -.It -Failing the above checks, if ``globbing'' is enabled, -local file names are expanded -according to the rules used in the -.Xr csh 1 ; -c.f. the -.Ic glob -command. -If the -.Nm ftp -command expects a single local file (.e.g. -.Ic put ) , -only the first filename generated by the "globbing" operation is used. -.It -For -.Ic mget -commands and -.Ic get -commands with unspecified local file names, the local filename is -the remote filename, which may be altered by a -.Ic case , -.Ic ntrans , -or -.Ic nmap -setting. -The resulting filename may then be altered if -.Ic runique -is on. -.It -For -.Ic mput -commands and -.Ic put -commands with unspecified remote file names, the remote filename is -the local filename, which may be altered by a -.Ic ntrans -or -.Ic nmap -setting. -The resulting filename may then be altered by the remote server if -.Ic sunique -is on. -.El -.Sh FILE TRANSFER PARAMETERS -The FTP specification specifies many parameters which may -affect a file transfer. -The -.Ic type -may be one of \*(Lqascii\*(Rq, \*(Lqimage\*(Rq (binary), -\*(Lqebcdic\*(Rq, and \*(Lqlocal byte size\*(Rq (for -.Tn PDP Ns -10's -and -.Tn PDP Ns -20's -mostly). -.Nm Ftp -supports the ascii and image types of file transfer, -plus local byte size 8 for -.Ic tenex -mode transfers. -.Pp -.Nm Ftp -supports only the default values for the remaining -file transfer parameters: -.Ic mode , -.Ic form , -and -.Ic struct . -.Sh THE .netrc FILE -The -.Pa .netrc -file contains login and initialization information -used by the auto-login process. -It resides in the user's home directory. -The following tokens are recognized; they may be separated by spaces, -tabs, or new-lines: -.Bl -tag -width password -.It Ic machine Ar name -Identify a remote machine -.Ar name . -The auto-login process searches the -.Pa .netrc -file for a -.Ic machine -token that matches the remote machine specified on the -.Nm ftp -command line or as an -.Ic open -command argument. -Once a match is made, the subsequent -.Pa .netrc -tokens are processed, -stopping when the end of file is reached or another -.Ic machine -or a -.Ic default -token is encountered. -.It Ic default -This is the same as -.Ic machine -.Ar name -except that -.Ic default -matches any name. -There can be only one -.Ic default -token, and it must be after all -.Ic machine -tokens. -This is normally used as: -.Pp -.Dl default login anonymous password user@site -.Pp -thereby giving the user -.Ar automatic -anonymous ftp login to -machines not specified in -.Pa .netrc . -This can be overridden -by using the -.Fl n -flag to disable auto-login. -.It Ic login Ar name -Identify a user on the remote machine. -If this token is present, the auto-login process will initiate -a login using the specified -.Ar name . -.It Ic password Ar string -Supply a password. -If this token is present, the auto-login process will supply the -specified string if the remote server requires a password as part -of the login process. -Note that if this token is present in the -.Pa .netrc -file for any user other -than -.Ar anonymous , -.Nm ftp -will abort the auto-login process if the -.Pa .netrc -is readable by -anyone besides the user. -.It Ic account Ar string -Supply an additional account password. -If this token is present, the auto-login process will supply the -specified string if the remote server requires an additional -account password, or the auto-login process will initiate an -.Dv ACCT -command if it does not. -.It Ic macdef Ar name -Define a macro. -This token functions like the -.Nm ftp -.Ic macdef -command functions. -A macro is defined with the specified name; its contents begin with the -next -.Pa .netrc -line and continue until a null line (consecutive new-line -characters) is encountered. -If a macro named -.Ic init -is defined, it is automatically executed as the last step in the -auto-login process. -.El -.Sh ENVIRONMENT -.Nm Ftp -uses the following environment variables. -.Bl -tag -width Fl -.It Ev HOME -For default location of a -.Pa .netrc -file, if one exists. -.It Ev SHELL -For default shell. -.El -.Sh SEE ALSO -.Xr ftpd 8 -.Rs -.%T RFC2228 -.Re -.Sh HISTORY -The -.Nm ftp -command appeared in -.Bx 4.2 . -.Sh BUGS -Correct execution of many commands depends upon proper behavior -by the remote server. -.Pp -An error in the treatment of carriage returns -in the -.Bx 4.2 -ascii-mode transfer code -has been corrected. -This correction may result in incorrect transfers of binary files -to and from -.Bx 4.2 -servers using the ascii type. -Avoid this problem by using the binary image type. diff --git a/crypto/heimdal/appl/ftp/ftp/ftp.c b/crypto/heimdal/appl/ftp/ftp/ftp.c deleted file mode 100644 index 0a00bd245667..000000000000 --- a/crypto/heimdal/appl/ftp/ftp/ftp.c +++ /dev/null @@ -1,1780 +0,0 @@ -/* - * Copyright (c) 1985, 1989, 1993, 1994 - * The Regents of the University of California.

The server uses the -.Tn TCP -protocol -and listens at the port specified in the -.Dq ftp -service specification; see -.Xr services 5 . -.Pp -Available options: -.Bl -tag -width Ds -.It Fl a -Select the level of authentication required. Kerberised login can not -be turned off. The default is to only allow kerberised login. Other -possibilities can be turned on by giving a string of comma separated -flags as argument to -.Fl a . -Recognised flags are: -.Bl -tag -width plain -.It Ar plain -Allow logging in with plaintext password. The password can be a(n) OTP -or an ordinary password. -.It Ar otp -Same as -.Ar plain , -but only OTP is allowed. -.It Ar ftp -Allow anonymous login. -.El -.Pp -The following combination modes exists for backwards compatibility: -.Bl -tag -width plain -.It Ar none -Same as -.Ar plain,ftp . -.It Ar safe -Same as -.Ar ftp . -.It Ar user -Ignored. -.El -.It Fl d -Debugging information is written to the syslog using LOG_FTP. -.It Fl g -Anonymous users will get a umask of -.Ar umask . -.It Fl -gss-bindings -require the peer to use GSS-API bindings (ie make sure IP addresses match). -.It Fl i -Open a socket and wait for a connection. This is mainly used for -debugging when ftpd isn't started by inetd. -.It Fl l -Each successful and failed -.Xr ftp 1 -session is logged using syslog with a facility of LOG_FTP. -If this option is specified twice, the retrieve (get), store (put), append, -delete, make directory, remove directory and rename operations and -their filename arguments are also logged. -.It Fl p -Use -.Ar port -(a service name or number) instead of the default -.Ar ftp/tcp . -.It Fl T -A client may also request a different timeout period; -the maximum period allowed may be set to -.Ar timeout -seconds with the -.Fl T -option. -The default limit is 2 hours. -.It Fl t -The inactivity timeout period is set to -.Ar timeout -seconds (the default is 15 minutes). -.It Fl u -Set the initial umask to something else than the default 027. -.It Fl U -In previous versions of -.Nm ftpd , -when a passive mode client requested a data connection to the server, the -server would use data ports in the range 1024..4999.

It is intended to be run by -system daemons like -.Xr getty 8 -or -.Xr telnetd 8 . -If you are already logged in, but want to change to another user, you -should use -.Xr su 1 . -.Pp -A username can be given on the command line, else one will be prompted -for. -.Pp -A password is required to login, unless the -.Fl f -option is given (indicating that the calling program has already done -proper authentication). With -.Fl f -the user will be logged in without further questions. -.Pp -For password authentication Kerberos 5, Kerberos 4 (if compiled in), -OTP (if compiled in) and local -.No ( Pa /etc/passwd ) -passwords are supported. OTP will be used if the the user is -registered to use it, and -.Nm login -is given the option -.Fl a Li otp . -When using OTP, a challenge is shown to the user. -.Pp -Further options are: -.Bl -tag -width Ds -.It Fl a Ar string -Which authentication mode to use, the only supported value is -currently -.Dq otp . -.It Fl f -Indicates that the user is already authenticated. This happens, for -instance, when login is started by telnetd, and the user has proved -authentic via Kerberos. -.It Fl h Ar hostname -Indicates which host the user is logging in from. This is passed from -telnetd, and is entered into the login database. -.It Fl p -This tells -.Nm login -to preserve all environment variables. If not given, only the -.Dv TERM -and -.Dv TZ -variables are preserved. It could be a security risk to pass random -variables to -.Nm login -or the user shell, so the calling daemon should make sure it only -passes -.Dq safe -variables. -.El -.Pp -The process of logging user in proceeds as follows. -.Pp -First a check is made that logins are allowed at all. This usually -means checking -.Pa /etc/nologin . -If it exists, and the user trying to login is not root, the contents -is printed, and then login exits. -.Pp -Then various system parameters are set up, like changing the owner of -the tty to the user, setting up signals, setting the group list, and -user and group id. Also various machine specific tasks are performed. -.Pp -Next -.Nm login -changes to the users home directory, or if that fails, to -.Pa / . -The environment is setup, by adding some required variables (such as -.Dv PATH ) , -and also authentication related ones (such as -.Dv KRB5CCNAME ) . -If an environment file exists -.No ( Pa /etc/environment ) , -variables are set according to -it. -.Pp -If one or more login message files are configured, their contents is -printed to the terminal. -.Pp -If a login time command is configured, it is executed. A logout time -command can also be configured, which makes -.Nm login -fork, and wait for the user shell to exit, and then run the command. -This can be used to clean up user credentials. -.Pp -Finally, the user's shell is executed. If the user logging in is root, -and root's login shell does not exist, a default shell (usually -.Pa /bin/sh ) -is also tried before giving up. -.Sh ENVIRONMENT -These environment variables are set by login (not including ones set by -.Pa /etc/environment ) : -.Pp -.Bl -tag -compact -width USERXXLOGNAME -.It Dv PATH -the default system path -.It Dv HOME -the user's home directory (or possibly -.Pa / ) -.It Dv USER , Dv LOGNAME -both set to the username -.It Dv SHELL -the user's shell -.It Dv TERM , Dv TZ -set to whatever is passed to -.Nm login -.It Dv KRB5CCNAME -if the password is verified via Kerberos 5, this will point to the -credentials cache file -.It Dv KRBTKFILE -if the password is verified via Kerberos 4, this will point to the -ticket file -.El -.Sh FILES -.Bl -tag -compact -width Ds -.It Pa /etc/environment -Contains a set of environment variables that should be set in addition -to the ones above.

It will be called without arguments. This program will be -the parent process of the spawned shell. -.It Li motd -A comma separated list of text files that will be printed to the -user's terminal before starting the shell. The string -.Li welcome -works similarly, but points to a single file. -.It Li limits -Points to a file containing ulimit settings for various users. Syntax -is inspired by what pam_limits uses, and the default is -.Pa /etc/security/limits.conf . -.El -.It Pa /etc/nologin -If it exists, login is denied to all but root. The contents of this -file is printed before login exits. -.El -.Pp -Other -.Nm login -programs typically print all sorts of information by default, such as -last time you logged in, if you have mail, and system message files. -This version of -.Nm login -does not, so there is no reason for -.Pa .hushlogin -files or similar. We feel that these tasks are best left to the user's -shell, but the -.Li login_program -facility allows for a shell independent solution, if that is desired. -.Sh EXAMPLES -A -.Pa login.conf -file could look like: -.Bd -literal -offset indent -default:\\ - :motd=/etc/motd,/etc/motd.local:\\ - :limits=/etc/limits.conf: -.Ed -.Pp -The -.Pa limits.conf -file consists of a table with four whitespace separated fields. First -field is a username or a groupname (prefixed with -.Sq @ ) , -or -.Sq * . -Second field is -.Sq soft , -.Sq hard , -or -.Sq - -(the last meaning both soft and hard). -Third field is a limit name (such as -.Sq cpu -or -.Sq core ) . -Last field is the limit value (a number or -.Sq - -for unlimited). In the case of data sizes, the value is in kilobytes, -and cputime is in minutes. -.Sh SEE ALSO -.Xr su 1 , -.Xr login.access 5 , -.Xr getty 8 , -.Xr telnetd 8 -.Sh AUTHORS -This login program was written for the Heimdal Kerberos 5 -implementation.

The magic string ALL matches all users. -A group will match if the user is a member of that group, or it is the -user's primary group. -.It -The third field is a list of ttys, or network names. A network name -can be either a hostname, a domain (indicated by a starting period), -or a netgroup. As with the user list, ALL matches anything.

It provides an authenticated remote command execution -service. Supported options are: -.Bl -tag -width Ds -.It Xo -.Fl n , -.Fl -no-keepalive -.Xc -Disables keep-alive messages. -Keep-alives are packets sent at certain intervals to make sure that the -client is still there, even when it doesn't send any data. -.It Xo -.Fl k , -.Fl -kerberos -.Xc -Assume that clients connecting to this server will use some form of -Kerberos authentication. See the -.Sx EXAMPLES -section for a sample -.Xr inetd.conf 5 -configuration. -.It Xo -.Fl x , -.Fl -encrypt -.Xc -For Kerberos 4 this means that the connections are encrypted. Kerberos -5 can negotiate encryption even without this option, but if it's -present -.Nm -will deny unencrypted connections. This option implies -.Fl k . -.\".It Xo -.\".Fl l , -.\".Fl -no-rhosts -.\".Xc -.\"When using old port-based authentication, the user's -.\".Pa .rhosts -.\"files are normally checked. This option disables this. -.It Xo -.Fl v , -.Fl -vacuous -.Xc -If the connecting client does not use any Kerberised authentication, -print a message that complains about this fact, and exit. This is -helpful if you want to move away from old port-based authentication. -.It Xo -.Fl P -.Xc -When using the AFS filesystem, users' authentication tokens are put in -something called a PAG (Process Authentication Group). Multiple -processes can share a PAG, but normally each login session has its own -PAG. This option disables the -.Fn setpag -call, so all tokens will be put in the default (uid-based) PAG, making -it possible to share tokens between sessions. This is only useful in -peculiar environments, such as some batch systems. -.It Xo -.Fl i , -.Fl -no-inetd -.Xc -The -.Fl i -option will cause -.Nm -to create a socket, instead of assuming that its stdin came from -.Xr inetd 8 . -This is mostly useful for debugging. -.It Xo -.Fl p Ar port , -.Fl -port= Ns Ar port -.Xc -Port to use with -.Fl i . -.It Xo -.Fl a -.Xc -This flag is for backwards compatibility only. -.It Xo -.Fl L -.Xc -This flag enables logging of connections to -.Xr syslogd 8 . -This option is always on in this implementation. -.El -.\".Sh ENVIRONMENT -.Sh FILES -.Bl -tag -width /etc/hosts.equiv -compact -.It Pa /etc/hosts.equiv -.It Pa ~/.rhosts -.El -.Sh EXAMPLES -The following can be used to enable Kerberised rsh in -.Xr inetd.cond 5 , -while disabling non-Kerberised connections: -.Bd -literal -shell stream tcp nowait root /usr/libexec/rshd rshd -v -kshell stream tcp nowait root /usr/libexec/rshd rshd -k -ekshell stream tcp nowait root /usr/libexec/rshd rshd -kx -.Ed -.\".Sh DIAGNOSTICS -.Sh SEE ALSO -.Xr rsh 1 , -.Xr iruserok 3 -.\".Sh STANDARDS -.Sh HISTORY -The -.Nm -command appeared in -.Bx 4.2 . -.Sh AUTHORS -This implementation of -.Nm -was written as part of the Heimdal Kerberos 5 implementation. -.\".Sh BUGS diff --git a/crypto/heimdal/appl/rsh/rshd.c b/crypto/heimdal/appl/rsh/rshd.c deleted file mode 100644 index 852327ad6705..000000000000 --- a/crypto/heimdal/appl/rsh/rshd.c +++ /dev/null @@ -1,1063 +0,0 @@ -/* - * Copyright (c) 1997-2007 Kungliga Tekniska Högskolan - * (Royal Institute of Technology, Stockholm, Sweden). - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * - * 1.

The - AUTHENTICATION option is fairly well defined, and - an option number has been assigned to it. The - ENCRYPTION option is still in a state of flux; an - option number has been assigned to, but it is still - subject to change. The code is provided in this release - for experimental and testing purposes. - - The telnet "send" command can now be used to send - do/dont/will/wont commands, with any telnet option - name. The rules for when do/dont/will/wont are sent - are still followed, so just because the user requests - that one of these be sent doesn't mean that it will - be sent... - - The telnet "getstatus" command no longer requires - that option printing be enabled to see the response - to the "DO STATUS" command. - - A -n flag has been added to telnetd to disable - keepalives. - - A new telnet command, "auth" has been added (if - AUTHENTICATE is defined). It has four sub-commands, - "status", "disable", "enable" and "help". - - A new telnet command, "encrypt" has been added (if - ENCRYPT is defined). It has many sub-commands: - "enable", "type", "start", "stop", "input", - "-input", "output", "-output", "status", and "help". - - The LOGOUT option is now supported by both telnet - and telnetd, a new command, "logout", was added - to support this. - - Several new toggle options were added: - "autoencrypt", "autodecrypt", "autologin", "authdebug", - "encdebug", "skiprc", "verbose_encrypt" - - An "rlogin" interface has been added. If the program - is named "rlogin", or the "-r" flag is given, then - an rlogin type of interface will be used. - ~. Terminates the session - ~<susp> Suspend the session - ~^] Escape to telnet command mode - ~~ Pass through the ~. - BUG: If you type the rlogin escape character - in the middle of a line while in rlogin - mode, you cannot erase it or any characters - before it. Hopefully this can be fixed - in a future release... - - General changes: - - A "libtelnet.a" has now been created. This libraray - contains code that is common to both telnet and - telnetd. This is also where library routines that - are needed, but are not in the standard C library, - are placed. - - The makefiles have been re-done. All of the site - specific configuration information has now been put - into a single "Config.generic" file, in the top level - directory. Changing this one file will take care of - all three subdirectories. Also, to add a new/local - definition, a "Config.local" file may be created - at the top level; if that file exists, the subdirectories - will use that file instead of "Config.generic". - - Many 1-2 line functions in commands.c have been - removed, and just inserted in-line, or replaced - with a macro. - - Bug Fixes: - - The non-termio code in both telnet and telnetd was - setting/clearing CTLECH in the sg_flags word. This - was incorrect, and has been changed to set/clear the - LCTLECH bit in the local mode word. - - The SRCRT #define has been removed. If IP_OPTIONS - and IPPROTO_IP are defined on the system, then the - source route code is automatically enabled. - - The NO_GETTYTAB #define has been removed; there - is a compatability routine that can be built into - libtelnet to achive the same results. - - The server, telnetd, has been switched to use getopt() - for parsing the argument list. - - The code for getting the input/output speeds via - cfgetispeed()/cfgetospeed() was still not quite - right in telnet. Posix says if the ispeed is 0, - then it is really equal to the ospeed. - - The suboption processing code in telnet now has - explicit checks to make sure that we received - the entire suboption (telnetd was already doing this). - - The telnet code for processing the terminal type - could cause a core dump if an existing connection - was closed, and a new connection opened without - exiting telnet. - - Telnetd was doing a TCSADRAIN when setting the new - terminal settings; This is not good, because it means - that the tcsetattr() will hang waiting for output to - drain, and telnetd is the only one that will drain - the output... The fix is to use TCSANOW which does - not wait. - - Telnetd was improperly setting/clearing the ISTRIP - flag in the c_lflag field, it should be using the - c_iflag field. - - When the child process of telnetd was opening the - slave side of the pty, it was re-setting the EXTPROC - bit too early, and some of the other initialization - code was wiping it out. This would cause telnetd - to go out of linemode and into single character mode. - - One instance of leaving linemode in telnetd forgot - to send a WILL ECHO to the client, the net result - would be that the user would see double character - echo. - - If the MODE was being changed several times very - quickly, telnetd could get out of sync with the - state changes and the returning acks; and wind up - being left in the wrong state. - -September 14, 1990: - - Switch the client to use getopt() for parsing the - argument list. The 4.3Reno getopt.c is included for - systems that don't have getopt(). - - Use the posix _POSIX_VDISABLE value for what value - to use when disabling special characters. If this - is undefined, it defaults to 0x3ff. - - For non-termio systems, TIOCSETP was being used to - change the state of the terminal. This causes the - input queue to be flushed, which we don't want. This - is now changed to TIOCSETN. - - Take out the "#ifdef notdef" around the code in the - server that generates a "sync" when the pty oputput - is flushed. The potential problem is that some older - telnet clients may go into an infinate loop when they - receive a "sync", if so, the server can be compiled - with "NO_URGENT" defined. - - Fix the client where it was setting/clearing the OPOST - bit in the c_lflag field, not the c_oflag field. - - Fix the client where it was setting/clearing the ISTRIP - bit in the c_lflag field, not the c_iflag field. (On - 4.3Reno, this is the ECHOPRT bit in the c_lflag field.) - The client also had its interpretation of WILL BINARY - and DO BINARY reversed. - - Fix a bug in client that would cause a core dump when - attempting to remove the last environment variable. - - In the client, there were a few places were switch() - was being passed a character, and if it was a negative - value, it could get sign extended, and not match - the 8 bit case statements. The fix is to and the - switch value with 0xff. - - Add a couple more printoption() calls in the client, I - don't think there are any more places were a telnet - command can be received and not printed out when - "options" is on. - - A new flag has been added to the client, "-a". Currently, - this just causes the USER name to be sent across, in - the future this may be used to signify that automatic - authentication is requested. - - The USER variable is now only sent by the client if - the "-a" or "-l user" options are explicity used, or - if the user explicitly asks for the "USER" environment - variable to be exported. In the server, if it receives - the "USER" environment variable, it won't print out the - banner message, so that only "Password:" will be printed. - This makes the symantics more like rlogin, and should be - more familiar to the user. (People are not used to - getting a banner message, and then getting just a - "Password:" prompt.) - - Re-vamp the code for starting up the child login - process. The code was getting ugly, and it was - hard to tell what was really going on. What we - do now is after the fork(), in the child: - 1) make sure we have no controlling tty - 2) open and initialize the tty - 3) do a setsid()/setpgrp() - 4) makes the tty our controlling tty. - On some systems, #2 makes the tty our controlling - tty, and #4 is a no-op. The parent process does - a gets rid of any controlling tty after the child - is fork()ed. - - Use the strdup() library routine in telnet, instead - of the local savestr() routine. If you don't have - strdup(), you need to define NO_STRDUP. - - Add support for ^T (SIGINFO/VSTATUS), found in the - 4.3Reno distribution. This maps to the AYT character. - You need a 4-line bugfix in the kernel to get this - to work properly: - - > *** tty_pty.c.ORG Tue Sep 11 09:41:53 1990 - > --- tty_pty.c Tue Sep 11 17:48:03 1990 - > *************** - > *** 609,613 **** - > if ((tp->t_lflag&NOFLSH) == 0) - > ttyflush(tp, FREAD|FWRITE); - > ! pgsignal(tp->t_pgrp, *(unsigned int *)data); - > return(0); - > } - > --- 609,616 ---- - > if ((tp->t_lflag&NOFLSH) == 0) - > ttyflush(tp, FREAD|FWRITE); - > ! pgsignal(tp->t_pgrp, *(unsigned int *)data, 1); - > ! if ((*(unsigned int *)data == SIGINFO) && - > ! ((tp->t_lflag&NOKERNINFO) == 0)) - > ! ttyinfo(tp); - > return(0); - > } - - The client is now smarter when setting the telnet escape - character; it only sets it to one of VEOL and VEOL2 if - one of them is undefined, and the other one is not already - defined to the telnet escape character. - - Handle TERMIOS systems that have seperate input and output - line speed settings imbedded in the flags. - - Many other minor bug fixes. - -June 20, 1990: - Re-organize makefiles and source tree. The telnet/Source - directory is now gone, and all the source that was in - telnet/Source is now just in the telnet directory. - - Seperate makefile for each system are now gone. There - are two makefiles, Makefile and Makefile.generic. - The "Makefile" has the definitions for the various - system, and "Makefile.generic" does all the work. - There is a variable called "WHAT" that is used to - specify what to make. For example, in the telnet - directory, you might say: - make 4.4bsd WHAT=clean - to clean out the directory. - - Add support for the ENVIRON and XDISPLOC options. - In order for the server to work, login has to have - the "-p" option to preserve environment variables. - - Add the SOFT_TAB and LIT_ECHO modes in the LINEMODE support. - - Add the "-l user" option to command line and open command - (This is passed through the ENVIRON option). - - Add the "-e" command line option, for setting the escape - character. - - Add the "-D", diagnostic, option to the server. This allows - the server to print out debug information, which is very - useful when trying to debug a telnet that doesn't have any - debugging ability. - - Turn off the literal next character when not in LINEMODE. - - Don't recognize ^Y locally, just pass it through. - - Make minor modifications for Sun4.0 and Sun4.1 - - Add support for both FORW1 and FORW2 characters. The - telnet escpape character is set to whichever of the - two is not being used. If both are in use, the escape - character is not set, so when in linemode the user will - have to follow the escape character with a <CR> or <EOF) - to get it passed through. - - Commands can now be put in single and double quotes, and - a backslash is now an escape character. This is needed - for allowing arbitrary strings to be assigned to environment - variables. - - Switch telnetd to use macros like telnet for keeping - track of the state of all the options. - - Fix telnetd's processing of options so that we always do - the right processing of the LINEMODE option, regardless - of who initiates the request to turn it on. Also, make - sure that if the other side went "WILL ECHO" in response - to our "DO ECHO", that we send a "DONT ECHO" to get the - option turned back off! - - Fix the TERMIOS setting of the terminal speed to handle both - BSD's seperate fields, and the SYSV method of CBAUD bits. - - Change how we deal with the other side refusing to enable - an option. The sequence used to be: send DO option; receive - WONT option; send DONT option. Now, the sequence is: send - DO option; receive WONT option. Both should be valid - according to the spec, but there has been at least one - client implementation of telnet identified that can get - really confused by this. (The exact sequence, from a trace - on the server side, is (numbers are number of responses that - we expect to get after that line...): - - send WILL ECHO 1 (initial request) - send WONT ECHO 2 (server is changing state) - recv DO ECHO 1 (first reply, ok. expect DONT ECHO next) - send WILL ECHO 2 (server changes state again) - recv DONT ECHO 1 (second reply, ok. expect DO ECHO next) - recv DONT ECHO 0 (third reply, wrong answer. got DONT!!!) - *** send WONT ECHO (send WONT to acknowledge the DONT) - send WILL ECHO 1 (ask again to enable option) - recv DO ECHO 0 - - recv DONT ECHO 0 - send WONT ECHO 1 - recv DONT ECHO 0 - recv DO ECHO 1 - send WILL ECHO 0 - (and the last 5 lines loop forever) - - The line with the "***" is last of the WILL/DONT/WONT sequence. - The change to the server to not generate that makes this same - example become: - - send will ECHO 1 - send wont ECHO 2 - recv do ECHO 1 - send will ECHO 2 - recv dont ECHO 1 - recv dont ECHO 0 - recv do ECHO 1 - send will ECHO 0 - - There is other option negotiation going on, and not sending - the third part changes some of the timings, but this specific - example no longer gets stuck in a loop. The "telnet.state" - file has been modified to reflect this change to the algorithm. - - A bunch of miscellaneous bug fixes and changes to make - lint happier. - - This version of telnet also has some KERBEROS stuff in - it. This has not been tested, it uses an un-authorized - telnet option number, and uses an out-of-date version - of the (still being defined) AUTHENTICATION option. - There is no support for this code, do not enable it. - - -March 1, 1990: -CHANGES/BUGFIXES SINCE LAST RELEASE: - Some support for IP TOS has been added. Requires that the - kernel support the IP_TOS socket option (currently this - is only in UNICOS 6.0). - - Both telnet and telnetd now use the cc_t typedef. typedefs are - included for systems that don't have it (in termios.h). - - SLC_SUSP was not supported properly before. It is now. - - IAC EOF was not translated properly in telnetd for SYSV_TERMIO - when not in linemode. It now saves a copy of the VEOF character, - so that when ICANON is turned off and we can't trust it anymore - (because it is now the VMIN character) we use the saved value. - - There were two missing "break" commands in the linemode - processing code in telnetd. - - Telnetd wasn't setting the kernel window size information - properly. It was using the rows for both rows and columns... - -Questions/comments go to - David Borman - Cray Research, Inc. - 655F Lone Oak Drive - Eagan, MN 55123 - dab@cray.com. - -README: You are reading it. - -Config.generic: - This file contains all the OS specific definitions. It - has pre-definitions for many common system types, and is - in standard makefile fromat. See the comments at the top - of the file for more information. - -Config.local: - This is not part of the distribution, but if this file exists, - it is used instead of "Config.generic". This allows site - specific configuration without having to modify the distributed - "Config.generic" file. - -kern.diff: - This file contains the diffs for the changes needed for the - kernel to support LINEMODE is the server. These changes are - for a 4.3BSD system. You may need to make some changes for - your particular system. - - There is a new bit in the terminal state word, TS_EXTPROC. - When this bit is set, several aspects of the terminal driver - are disabled. Input line editing, character echo, and - mapping of signals are all disabled. This allows the telnetd - to turn of these functions when in linemode, but still keep - track of what state the user wants the terminal to be in. - - New ioctl()s: - - TIOCEXT Turn on/off the TS_EXTPROC bit - TIOCGSTATE Get t_state of tty to look at TS_EXTPROC bit - TIOCSIG Generate a signal to processes in the - current process group of the pty. - - There is a new mode for packet driver, the TIOCPKT_IOCTL bit. - When packet mode is turned on in the pty, and the TS_EXTPROC - bit is set, then whenever the state of the pty is changed, the - next read on the master side of the pty will have the TIOCPKT_IOCTL - bit set, and the data will contain the following: - struct xx { - struct sgttyb a; - struct tchars b; - struct ltchars c; - int t_state; - int t_flags; - } - This allows the process on the server side of the pty to know - when the state of the terminal has changed, and what the new - state is. - - However, if you define USE_TERMIO or SYSV_TERMIO, the code will - expect that the structure returned in the TIOCPKT_IOCTL is - the termio/termios structure. - -stty.diff: - This file contains the changes needed for the stty(1) program - to report on the current status of the TS_EXTPROC bit. It also - allows the user to turn on/off the TS_EXTPROC bit. This is useful - because it allows the user to say "stty -extproc", and the - LINEMODE option will be automatically disabled, and saying "stty - extproc" will re-enable the LINEMODE option. - -telnet.state: - Both the client and server have code in them to deal - with option negotiation loops. The algorithm that is - used is described in this file. - -telnet: - This directory contains the client code. No kernel changes are - needed to use this code. - -telnetd: - This directory contains the server code. If LINEMODE or KLUDGELINEMODE - are defined, then the kernel modifications listed above are needed. - -libtelnet: - This directory contains code that is common to both the client - and the server. - -arpa: - This directory has a new <arpa/telnet.h> - -libtelnet/Makefile.4.4: -telnet/Makefile.4.4: -telnetd/Makefile.4.4: - These are the makefiles that can be used on a 4.3Reno - system when this software is installed in /usr/src/lib/libtelnet, - /usr/src/libexec/telnetd, and /usr/src/usr.bin/telnet. - - -The following TELNET options are supported: - - LINEMODE: - The LINEMODE option is supported as per RFC1116. The - FORWARDMASK option is not currently supported. - - BINARY: The client has the ability to turn on/off the BINARY - option in each direction. Turning on BINARY from - server to client causes the LITOUT bit to get set in - the terminal driver on both ends, turning on BINARY - from the client to the server causes the PASS8 bit - to get set in the terminal driver on both ends. - - TERMINAL-TYPE: - This is supported as per RFC1091. On the server side, - when a terminal type is received, termcap/terminfo - is consulted to determine if it is a known terminal - type. It keeps requesting terminal types until it - gets one that it recongnizes, or hits the end of the - list. The server side looks up the entry in the - termcap/terminfo data base, and generates a list of - names which it then passes one at a time to each - request for a terminal type, duplicating the last - entry in the list before cycling back to the beginning. - - NAWS: The Negotiate about Window Size, as per RFC 1073. - - TERMINAL-SPEED: - Implemented as per RFC 1079 - - TOGGLE-FLOW-CONTROL: - Implemented as per RFC 1080 - - TIMING-MARK: - As per RFC 860 - - SGA: As per RFC 858 - - ECHO: As per RFC 857 - - LOGOUT: As per RFC 727 - - STATUS: - The server will send its current status upon - request. It does not ask for the clients status. - The client will request the servers current status - from the "send getstatus" command. - - ENVIRON: - This option is currently being defined by the IETF - Telnet Working Group, and an RFC has not yet been - issued, but should be in the near future... - - X-DISPLAY-LOCATION: - This functionality can be done through the ENVIRON - option, it is added here for completeness. - - AUTHENTICATION: - This option is currently being defined by the IETF - Telnet Working Group, and an RFC has not yet been - issued. The basic framework is pretty much decided, - but the definitions for the specific authentication - schemes is still in a state of flux. - - ENCRYPTION: - This option is currently being defined by the IETF - Telnet Working Group, and an RFC has not yet been - issued. The draft RFC is still in a state of flux, - so this code may change in the future. diff --git a/crypto/heimdal/appl/telnet/arpa/telnet.h b/crypto/heimdal/appl/telnet/arpa/telnet.h deleted file mode 100644 index 5d9ef6001621..000000000000 --- a/crypto/heimdal/appl/telnet/arpa/telnet.h +++ /dev/null @@ -1,323 +0,0 @@ -/* - * Copyright (c) 1983, 1993 - * The Regents of the University of California.

This causes an attempt to -negotiate the -.Dv TELNET BINARY -option on both input and output. -.It Fl 7 -Do not try to negotiate -.Dv TELNET BINARY -option. -.It Fl E -Stops any character from being recognized as an escape character. -.It Fl F -If Kerberos V5 authentication is being used, the -.Fl F -option allows the local credentials to be forwarded -to the remote system, including any credentials that -have already been forwarded into the local environment. -.It Fl K -Specifies no automatic login to the remote system. -.It Fl L -Specifies an 8-bit data path on output. This causes the -BINARY option to be negotiated on output. -.It Fl S Ar tos -Sets the IP type-of-service (TOS) option for the telnet -connection to the value -.Ar tos , -which can be a numeric TOS value -or, on systems that support it, a symbolic -TOS name found in the /etc/iptos file. -.It Fl X Ar atype -Disables the -.Ar atype -type of authentication. -.It Fl a -Attempt automatic login. -Currently, this sends the user name via the -.Ev USER -variable -of the -.Ev ENVIRON -option if supported by the remote system. -The name used is that of the current user as returned by -.Xr getlogin 2 -if it agrees with the current user ID, -otherwise it is the name associated with the user ID. -.It Fl c -Disables the reading of the user's -.Pa \&.telnetrc -file. (See the -.Ic toggle skiprc -command on this man page.) -.It Fl d -Sets the initial value of the -.Ic debug -toggle to -.Dv TRUE -.It Fl e Ar escape char -Sets the initial -.Nm -.Nm telnet -escape character to -.Ar escape char . -If -.Ar escape char -is omitted, then -there will be no escape character. -.It Fl f -If Kerberos V5 authentication is being used, the -.Fl f -option allows the local credentials to be forwarded to the remote system. -.It Fl k Ar realm -If Kerberos authentication is being used, the -.Fl k -option requests that telnet obtain tickets for the remote host in -realm realm instead of the remote host's realm, as determined -by -.Xr krb_realmofhost 3 . -.It Fl l Ar user -When connecting to the remote system, if the remote system -understands the -.Ev ENVIRON -option, then -.Ar user -will be sent to the remote system as the value for the variable USER. -This option implies the -.Fl a -option. -This option may also be used with the -.Ic open -command. -.It Fl n Ar tracefile -Opens -.Ar tracefile -for recording trace information. -See the -.Ic set tracefile -command below. -.It Fl r -Specifies a user interface similar to -.Xr rlogin 1 . -In this -mode, the escape character is set to the tilde (~) character, -unless modified by the -e option. -.It Fl x -Turn on encryption of the data stream. When this option is turned on, -.B telnet -will exit with an error if authentication cannot be negotiated or if -encryption cannot be turned on. -.It Ar host -Indicates the official name, an alias, or the Internet address -of a remote host. -.It Ar port -Indicates a port number (address of an application). If a number is -not specified, the default -.Nm telnet -port is used. -.El -.Pp -When in rlogin mode, a line of the form ~. disconnects from the -remote host; ~ is the telnet escape character. -Similarly, the line ~^Z suspends the telnet session. -The line ~^] escapes to the normal telnet escape prompt. -.Pp -Once a connection has been opened, -.Nm telnet -will attempt to enable the -.Dv TELNET LINEMODE -option. -If this fails, then -.Nm telnet -will revert to one of two input modes: -either \*(Lqcharacter at a time\*(Rq -or \*(Lqold line by line\*(Rq -depending on what the remote system supports. -.Pp -When -.Dv LINEMODE -is enabled, character processing is done on the -local system, under the control of the remote system. When input -editing or character echoing is to be disabled, the remote system -will relay that information. The remote system will also relay -changes to any special characters that happen on the remote -system, so that they can take effect on the local system. -.Pp -In \*(Lqcharacter at a time\*(Rq mode, most -text typed is immediately sent to the remote host for processing. -.Pp -In \*(Lqold line by line\*(Rq mode, all text is echoed locally, -and (normally) only completed lines are sent to the remote host. -The \*(Lqlocal echo character\*(Rq (initially \*(Lq^E\*(Rq) may be used -to turn off and on the local echo -(this would mostly be used to enter passwords -without the password being echoed). -.Pp -If the -.Dv LINEMODE -option is enabled, or if the -.Ic localchars -toggle is -.Dv TRUE -(the default for \*(Lqold line by line\*(Lq; see below), -the user's -.Ic quit , -.Ic intr , -and -.Ic flush -characters are trapped locally, and sent as -.Tn TELNET -protocol sequences to the remote side. -If -.Dv LINEMODE -has ever been enabled, then the user's -.Ic susp -and -.Ic eof -are also sent as -.Tn TELNET -protocol sequences, -and -.Ic quit -is sent as a -.Dv TELNET ABORT -instead of -.Dv BREAK -There are options (see -.Ic toggle -.Ic autoflush -and -.Ic toggle -.Ic autosynch -below) -which cause this action to flush subsequent output to the terminal -(until the remote host acknowledges the -.Tn TELNET -sequence) and flush previous terminal input -(in the case of -.Ic quit -and -.Ic intr ) . -.Pp -While connected to a remote host, -.Nm telnet -command mode may be entered by typing the -.Nm telnet -\*(Lqescape character\*(Rq (initially \*(Lq^]\*(Rq). -When in command mode, the normal terminal editing conventions are available. -.Pp -The following -.Nm telnet -commands are available. -Only enough of each command to uniquely identify it need be typed -(this is also true for arguments to the -.Ic mode , -.Ic set , -.Ic toggle , -.Ic unset , -.Ic slc , -.Ic environ , -and -.Ic display -commands). -.Pp -.Bl -tag -width "mode type" -.It Ic auth Ar argument ... -The auth command manipulates the information sent through the -.Dv TELNET AUTHENTICATE -option.

This option will call -login with an option so that only OTPs are accepted. The user can of -course still type secret information at the prompt. -.It none -This is the default state. -Authentication information is not required. -If no or insufficient authentication information -is provided, then the -.Xr login 1 -program will provide the necessary user -verification. -.It off -This disables the authentication code. -All user verification will happen through the -.Xr login 1 -program. -.El -.It Fl B -Ignored. -.It Fl D Ar debugmode -This option may be used for debugging purposes. -This allows -.Nm telnetd -to print out debugging information -to the connection, allowing the user to see what -.Nm telnetd -is doing. -There are several possible values for -.Ar debugmode : -.Bl -tag -width exercise -.It Cm options -Prints information about the negotiation of -.Tn TELNET -options. -.It Cm report -Prints the -.Cm options -information, plus some additional information -about what processing is going on. -.It Cm netdata -Displays the data stream received by -.Nm telnetd . -.It Cm ptydata -Displays data written to the pty. -.It Cm exercise -Has not been implemented yet. -.El -.It Fl e -require encryption to be turned on (in both direction) by the client -and disconnects if the client tries to turn the encryption off (in -either direction). -.It Fl h -Disables the printing of host-specific information before -login has been completed. -.It Fl k -.It Fl l -Ignored. -.It Fl n -Disable -.Dv TCP -keep-alives. Normally -.Nm telnetd -enables the -.Tn TCP -keep-alive mechanism to probe connections that -have been idle for some period of time to determine -if the client is still there, so that idle connections -from machines that have crashed or can no longer -be reached may be cleaned up. -.It Fl r Ar lowpty-highpty -This option is only enabled when -.Nm telnetd -is compiled for -.Dv UNICOS . -It specifies an inclusive range of pseudo-terminal devices to -use. If the system has sysconf variable -.Dv _SC_CRAY_NPTY -configured, the default pty search range is 0 to -.Dv _SC_CRAY_NPTY ; -otherwise, the default range is 0 to 128. Either -.Ar lowpty -or -.Ar highpty -may be omitted to allow changing -either end of the search range. If -.Ar lowpty -is omitted, the - character is still required so that -.Nm telnetd -can differentiate -.Ar highpty -from -.Ar lowpty . -.It Fl S Ar tos -.It Fl u Ar len -This option is used to specify the size of the field -in the -.Dv utmp -structure that holds the remote host name. -If the resolved host name is longer than -.Ar len , -the dotted decimal value will be used instead. -This allows hosts with very long host names that -overflow this field to still be uniquely identified. -Specifying -.Fl u0 -indicates that only dotted decimal addresses -should be put into the -.Pa utmp -file. -.It Fl U -This option causes -.Nm telnetd -to refuse connections from addresses that -cannot be mapped back into a symbolic name -via the -.Xr gethostbyaddr 3 -routine. -.It Fl X Ar authtype -This option is only valid if -.Nm telnetd -has been built with support for the authentication option. -It disables the use of -.Ar authtype -authentication, and -can be used to temporarily disable -a specific authentication type without having to recompile -.Nm telnetd . -.It Fl L Ar pathname -Specify pathname to an alternative login program. -.It Fl y -Makes -.Nm -not warn when a user is trying to login with a cleartext password. -.El -.Pp -.Nm Telnetd -operates by allocating a pseudo-terminal device (see -.Xr pty 4 ) -for a client, then creating a login process which has -the slave side of the pseudo-terminal as -.Dv stdin , -.Dv stdout -and -.Dv stderr . -.Nm Telnetd -manipulates the master side of the pseudo-terminal, -implementing the -.Tn TELNET -protocol and passing characters -between the remote client and the login process. -.Pp -When a -.Tn TELNET -session is started up, -.Nm telnetd -sends -.Tn TELNET -options to the client side indicating -a willingness to do the -following -.Tn TELNET -options, which are described in more detail below: -.Bd -literal -offset indent -DO AUTHENTICATION -WILL ENCRYPT -DO TERMINAL TYPE -DO TSPEED -DO XDISPLOC -DO NEW-ENVIRON -DO

"WILL ECHO" -When the -.Dv LINEMODE -option is enabled, a -.Dv WILL ECHO -or -.Dv WONT ECHO -will be sent to the client to indicate the -current state of terminal echoing. -When terminal echo is not desired, a -.Dv WILL ECHO -is sent to indicate that -.Tn telnetd -will take care of echoing any data that needs to be -echoed to the terminal, and then nothing is echoed. -When terminal echo is desired, a -.Dv WONT ECHO -is sent to indicate that -.Tn telnetd -will not be doing any terminal echoing, so the -client should do any terminal echoing that is needed. -.It "WILL BINARY" -Indicates that the client is willing to send a -8 bits of data, rather than the normal 7 bits -of the Network Virtual Terminal. -.It "WILL SGA" -Indicates that it will not be sending -.Dv IAC GA , -go ahead, commands. -.It "WILL STATUS" -Indicates a willingness to send the client, upon -request, of the current status of all -.Tn TELNET -options. -.It "WILL TIMING-MARK" -Whenever a -.Dv DO TIMING-MARK -command is received, it is always responded -to with a -.Dv WILL TIMING-MARK -.It "WILL LOGOUT" -When a -.Dv DO LOGOUT -is received, a -.Dv WILL LOGOUT -is sent in response, and the -.Tn TELNET -session is shut down. -.It "WILL ENCRYPT" -Only sent if -.Nm telnetd -is compiled with support for data encryption, and -indicates a willingness to decrypt -the data stream. -.El -.Pp -.Nm Telnetd -has support for enabling remotely the following -.Tn TELNET -options: -.Bl -tag -width "DO AUTHENTICATION" -.It "DO BINARY" -Sent to indicate that -.Tn telnetd -is willing to receive an 8 bit data stream. -.It "DO LFLOW" -Requests that the client handle flow control -characters remotely. -.It "DO ECHO" -This is not really supported, but is sent to identify a 4.2BSD -.Xr telnet 1 -client, which will improperly respond with -.Dv WILL ECHO . -If a -.Dv WILL ECHO -is received, a -.Dv DONT ECHO -will be sent in response. -.It "DO TERMINAL-TYPE" -Indicates a desire to be able to request the -name of the type of terminal that is attached -to the client side of the connection. -.It "DO SGA" -Indicates that it does not need to receive -.Dv IAC GA , -the go ahead command. -.It "DO NAWS" -Requests that the client inform the server when -the window (display) size changes. -.It "DO TERMINAL-SPEED" -Indicates a desire to be able to request information -about the speed of the serial line to which -the client is attached. -.It "DO XDISPLOC" -Indicates a desire to be able to request the name -of the X windows display that is associated with -the telnet client. -.It "DO NEW-ENVIRON" -Indicates a desire to be able to request environment -variable information, as described in RFC 1572. -.It "DO ENVIRON" -Indicates a desire to be able to request environment -variable information, as described in RFC 1408. -.It "DO LINEMODE" -Only sent if -.Nm telnetd -is compiled with support for linemode, and -requests that the client do line by line processing. -.It "DO TIMING-MARK" -Only sent if -.Nm telnetd -is compiled with support for both linemode and -kludge linemode, and the client responded with -.Dv WONT LINEMODE . -If the client responds with -.Dv WILL TM , -the it is assumed that the client supports -kludge linemode. -Note that the -.Op Fl k -option can be used to disable this. -.It "DO AUTHENTICATION" -Only sent if -.Nm telnetd -is compiled with support for authentication, and
