Re: Anyone know what TCP port 59 is used for?

[John <jjh@oitsec.umn.edu>]

Well, here's my guess...

This port is typically used to transfer files (DCC) between irc clients.
If your seeing lots of it, it usually means someone is sharing lots
of stuff on irc.  Typically the program mIRC + scripts is responsible
for this sort of thing.

See mirc  : http://www.mirc.com/
