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.
The Bahamut IRCD is based on the EFNet Hybrid IRCD and has many additional features primarily designed for the DALnet IRC network. Its features include very high performance, compatibility with Solaris, BSD and Linux and a high level of stability under very high load, as well as many improvements over the original EFNet code. Bahamut is not compatible with Dreamforge as of version 1.2.0.
pork is an ncurses-based AOL instant messenger client. It uses the OSCAR protocol (the one the Windows client uses) to access AIM. Pork features Perl scripting, an online help system, the ability to configure nearly all aspects of the program's look and feel, an alias system, and a powerful, fully configurable key binding system. It supports being logged in with more than one screen name at the same time. The default look and feel of the client is modeled after the ircII IRC client. Anyone comfortable using ircII (or any clients derived from it, e.g. epic, BitchX, etc.) will feel comfortable using pork.
TR-IRCD is an ircd and a collection of services programs for IRC networks. The ircd is heavily influenced by ircd-hybrid and Bahamut. It includes support for IRC extensions such as md5-encrypted hostnames, modules, threads, different protocols, channel modes, and languages. It supports IPv6 and Web-based configuration, and includes a proxy scanner.
