* Implement support for RFC 3514 (The Security Flag in the IPv4 Header).Matthew N. Dodd2003-04-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt) This fulfills the host requirements for userland support by way of the setsockopt() IP_EVIL_INTENT message. There are three sysctl tunables provided to govern system behavior. net.inet.ip.rfc3514: Enables support for rfc3514. As this is an Informational RFC and support is not yet widespread this option is disabled by default. net.inet.ip.hear_no_evil If set the host will discard all received evil packets. net.inet.ip.speak_no_evil If set the host will discard all transmitted evil packets. The IP statistics counter 'ips_evil' (available via 'netstat') provides information on the number of 'evil' packets recieved. For reference, the '-E' option to 'ping' has been provided to demonstrate and test the implementation. Notes: svn path=/head/; revision=112929

* The -A option (beep when packets are dropped) didn't work quiteIan Dowse2001-09-251-3/+6
| | | | | | | | | | | | | | | | right; after a single packet was dropped it beeped after every transmission. Change its implementation to only output a bell when there is an increase in the maximum value of the number of packets that were sent but not yet received. This has the benefit that even for very long round-trip times, ping -A will do roughly the right thing after a few inital false-positives. Reviewed by: ru Notes: svn path=/head/; revision=83940
* mdoc(7) police:Ruslan Ermilov2001-08-071-16/+17
| | | | | | | | | | Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text. Not only this slows down the mdoc(7) processing significantly, but it also has an undesired (in this case) effect of disabling hyphenation within the entire enclosed block.
