xchat not connecting, server crash

[MFernstrom]

I got it running on Debian, and I can connect with a telnet session, and it seems to be working fine.

Then I try to connect using xchat, since it's supposed to be an irc server, and the server crashes.

** Reason for termination =

[{file,"src/irc_s2c_fsm.erl"},{line,316}]},

This library isn't a full featured or debugged irc server/client (and I haven't worked on it in about 5 years). If you're interested in working on it, I think the problem will be with your client not sending a NICK command in the way that the library expects. A transcript of the commands your client sends would help a lot. The code is expecting a nick command around here https://github.com/archaelus/erlirc/blob/master/src/irc_s2c_fsm.erl#L89 , but it's getting something else and giving up. Possibly there's a setting in your client you can change, or it may be that the server-to-client fsm is too strict in the sequence of messages it requires.

My guess would be the order and sensitivity, xchat sends "cap ls", which I don't remember seeing in your code. I'll play around and see if I can figure it out
