BSD Vacation v2 is a rewrite of the 'vacation' program that has come with Sendmail (and thus *BSD) since about 1983. This version has been almost completely rewritten in an attempt to get it closer to RFC-2822 compliance than any previous version. It properly responds to the correct recipients, as per the RFC, and it correctly handles multi-line headers. The command-line interface is compatible with previous versions, and most recent add-on features from the various *BSD projects have been implemented, such as support for preloading the recent recipients database.
BSFlite is a minimalistic, line-based AIM client for Unix (including Mac OS X) and Win32. It is designed with simplicity and efficiency in mind and thus utilises as little RAM and CPU time as possible in order to be friendly to multiuser systems. It uses the OSCAR protocol to communicate with the AIM service.
BZip2/OSS-QM is the OSS-QM project's branch of bzip2, which contains a lot of fixes not yet in the original upstream. The primary goal is to provide QM'ed/fixed versions of upstream releases, so they can be built and used without additional patches, especially in sysrooted crosscompiling environments.
The Bait and Switch Honeypot System combines the snort Intrusion Detection System (IDS) with honeypot technology to create a system that reacts to hostile intrusion attempts by marking and then redirecting all "bad" traffic to a honeypot that partially mirrors your production system. Once switched, the would-be hacker is unknowingly attacking your honeypot instead of the real data, while your clients and/or users are still safely accessing the real system. Life goes on, your data is safe, and you get to learn about the bad guy as an added benefit. It works with Snort 1.9.0, 1.9.1, and 2.0.2.
