tiBot is an automated IRC connection, known as bot, intended to help channel ops manage their channels. There are already alot of other bots out there, but none had all I wanted in a bot, so i decided to build my own. It's currently not usable, but will have several new features in the future. Check the webpage for more information.
tircproxy is a full featured IRC proxy. It can proxy DCC CHAT, DCC SEND and other DCC requests transparently to the user, block common trojans (such as script.ini), hide the user's identity and more. It can be used with the Linux kernel or IPF transparent proxy features to transparently proxy IRC sessions.
