[Snort-users] sid-msg.map

Your first alert is for SID 24889, yet your search through rules and
sid-map is for 25568..  ??  Why was that?

When snorby shows the "Snort Alert.. blah blah". it's reading that
from the DB.  That information gets put into the DB from Barnyard2.

Barnyard2 reads the name of the rule from sid-msg.map (if it's
configured to read the right one).

When you update your rules (hopefully using pulledpork) it should
generate a new sid-msg.map.  Then you restart BY2 to read the new

If that's not the process you are doing, or you haven't restarted BY2
in a while.. then that's the problem.

You can do a UPDATE mysql command to change the name of the rule in the DB.
