Bitlbee is an IRC to other chat networks gateway. Bitlbee can be used as an IRC server which forwards everything you say to people on other chat networks like ICQ, MSN, Jabber or Yahoo.

How To Install

Bitlbee is available in Fedora since Fedora Core 5. It can be easily installed by typing (as root):

yum install bitlbee

If you would like to quick start, just run the following two commands:

chkconfig bitlbee on

After done, connect your favourite IRC client to host localhost, port 6667 and follow the short introduction into Bitlbee given there.
