# IRC - Internet Relay Chat - RFC 1459
# Pattern quality: good veryfast
#
# Usually runs on port 6666 or 6667
# Note that chat traffic runs on these ports, but IRC-DCC traffic (which
# can use much more bandwidth) uses a dynamically assigned port, so you
# must have the IRC connection tracking module in your kernel to classify
# this.
#
# This pattern has been tested and is believed to work well. If it does not
# work for you, or you believe it could be improved, please post to
# l7-filter-developers@lists.sf.net . This list may be subscribed to at

# First thing that happens is that the client sends NICK and USER, in
# either order. This allows MIRC color codes (\x02-\x0d instead of
# \x09-\x0d).
