oSpam is an anti-spam system based on Perl, qmail, and, optionally, vmailmgr. It features "one-day" email addresses for usenet postings: after a delay, the mails sent to your address will be put in quarantine waiting for a confirmation, or/and can be used as your main email address: all your contacts are listed in a file. If somebody which isn't in the list sends you an email, he will get a small and unique confirmation request, and then the email(s) will be delivered transparently.
The library can be used by developers to quickly add alternate passwd file support for virtual authentication, or by system administrators to trick programs into seeing a different password file, either at run time through the LD_PRELOAD variable, or at compile time with -laltpw during the linking process.
K-DBX is based on LibDBX (part of the ol2mbox project), and is able to load Outlook Express files and display their contents. If K-DBX loads the "folder.dbx" file, then it will display the folder structure as a tree on the left, allowing you to click on a folder to view its contents.
Hogwash is a layer 2 packet scrubber based on the snort signature engine. Hogwash sits in line, and drops packets based on signature matches. The rule set will be familiar to anyone that has used snort before. Hogwash supports passive host identification and adaptive rule sets for added accuracy.
