BitchX is the premiere IRC (Internet Relay Chat) client. It originally was a modified version of the popular ircII client, and the features were eventually merged into the EPIC IRC client. The current development is aimed at merging the client back to a current branch of EPIC and bringing compatibility and stability back to the client, while bringing the features that are BitchX into a new client.
Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attackers' IP addresses into the ipfw2 table, effectively blocking them. Addresses are automatically removed from the table after specified amount of time. Bruteblock uses regular expressions to parse logs, which gives it enough flexibility to be used with almost any network service. Bruteblock doesn't use any external programs and works with ipfw2 tables via the raw sockets API.
This is a patch for the popular Cistron RADIUS server to put the "users" file, including passwords in an LDAP directory. Integrating the radius server with LDAP has many benefits: all user accounts can be put in a central store, the store is easily replicated, and writing account management scripts also become easier with the multitudes of freely available LDAP browsers and administration tools.
The "Click" modular router project is a fast, easily-extended software router. It's designed to handle all stages of IP transactions, and includes support for packet mangling, packet scheduling, queueing, etc. It can be run standalone on most Unix OSes or as a module for the Linux or Exopc kernels.
