snort-0.99b3.tar.gz

Snort is an extremely versatile packet logger. This version features dramatic speed improvements, a more logically laid out packet header print out, packet statistics, fragment detection, and more complete IP header decoding. Improved timestamping (down to the millisecond) implemented. This release has TCP and IP option decoding, and some new rules stuff. You can now specify port ranges (or greater than/less than) and TCP flags in rules. This allows you to do things like this: alert tcp any any -> 192.168.1.0/24 :1024 {SF} 192.168.1.0/24 6000:6010 which will pick out inbound traffic going ports 6000 thru 6010. Also includes bugfixes, cleaned up fragment printout routines, truncated packet fragments get dumped in their own file, rules processor routine recoded and more flexible, much more. Several important bugfixes in this release, plus recoded IP/TCP option decoding, revised packet printout routines, and now logs illegal TCP and IP options as well in an IP_BOGUS log file.
