cerberus is a modular and robust network operator and drone monitoring service designed to protect IRC networks from common threats that plague the community. It uses a BIND9-style configuration file with a mix of Perl syntax. It includes a map module that displays a server map along with basic information, stats/protocol for core protocol support, sql, an interface to DBI, modcontrol for controlling modules in use via IRC, login, operlist for displaying a list of all operators on the network, and more. It was designed for use with pure TS6 networks such as ircd-ratbox and ircd-hybrid.
SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing services in the Internet. It can be used to send any kind of messages, in addition to normal text messages. This includes multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.
Supybot is a clearly-written Python IRC framework and bot, intended to be both easily extensible and very flexible. Several modules are included by default. Numerous plugins are already written, including Google, Factoids, RSS, Quotes, and Relay. Plugins and their commands achieve greater utility via command nesting, something that no other IRC bot does. The user database is based on "capabilities" rather than obscure flags or arbitrary numeric "userlevels", giving the bot flexibility and fine-grained control (think ACLs vs. standard *nix permissions). Developing your own additions to the bot is simple with the base classes provided; writing a new command for the bot is as simple as writing a function. Unlike many other IRC frameworks, this simplicity is achieved at no cost to generality, which lets new programmers and old programmers alike feel at home in the framework.
OpenIM is a Java implementation of a Jabber server. It is a complete rewrite of the Jaba Server project, and it supports the Jabber server to server communication protocol. It also supports Presence, Message, and Roster. Persistent storage is done in an XML file using XStream lib. It has been tested successfully with many clients such as Exodus, Rhymbox, GAIM, Psi, Greenthumb, and the Kopete.
Sentinel provides statistical and operator services for EFnet, IRCnet, and Dalnet IRC daemons. It supports Hybrid/Comstud (5, 6, 7, comstud 1.x, CSr, csircd, ircd-ratbox), and Bahamut. It features a StatServ, a SplitServ, flood protection, customized HTML output, a Jupe service, a channel search engine, and a number of drone/clone tracking tools. It fully supports many Hybrid 6 and 7 extensions.
Damascus is a GTK+ 2.x client for the Gale communication protocol. It is somewhat modelled after IM/ICQ-style interfaces. If you don't know what Gale is, this client probably won't be very useful; you need a valid Gale key to send anything, and Damascus can't generate them (yet). Gale is also scary and confusing.
