Re: Snort 2.9.0.2 / barnyard2 / base 1.4.5 signature not displayed and is unclassified

[Kevin Ross <kevross33 () googlemail com>]

You need to include your gen-msg.map file in barnyard.conf. What it means if
a number and GID is showing in the name in base instead of a proper name is
that it doesn't have a -msg.map file such as it is missing from sid-msg.map,
gen-msg.map etc. If you include them to be used then the name will appear.
You may enounter the same issue if you do not update your sid-msg.map file
and alerts appear for stuff (if you don't do it by script).
