6 # Usually runs on port 6666 or 6667
7 # Note that chat traffic runs on these ports, but IRC-DCC traffic (which
8 # can use much more bandwidth) uses a dynamically assigned port, so you
9 # must have the IRC connection tracking module in your kernel to classify
12 # This pattern has been tested and is believed to work well.
15 # First thing that happens is that the client sends NICK and USER, in
16 # either order. This allows MIRC color codes (\x02-\x0d instead of
18 ^(nick[\x09-\x0d -~]*user[\x09-\x0d -~]*:|user[\x09-\x0d -~]*:[\x02-\x0d -~]*nick[\x09-\x0d -~]*\x0d\x0a)
