Is it possible to host an IRC server on a RaQ4? If it is possible...how? which software do I need?

Thx,

Juan

Yes of course it's possible. IRC servers you can run:

Bare in mind IRC processes are the biggest attractions to DOS attacks against servers. If you're renting a dedicated server chances are your provider will prohibit the running of IRC servers, bots infact any IRC process.
