[Snort-users] Broken rule set for 1.8.7

You guessed it!
The symptom on linux was that the actual text for the classtype (indexed
by classtype from the classification file) was missing and in its place
was the string " sid".
I'm fairly certain that another user thought that the classtype text in
the classification file was too long and causing a core dump, was the
result of the multiple classtype options for that one rule. That rule
does not have to trigger, just one of the rules in the class "classtype".
I'd be interested if the MAC actually works, or their is some other innocuous
symptom similar to missing classification text.
Onward and upward,
