same here... lots of FP's. ------------------------
Hmmm... no doc file or references for this rule so I don't know what it is trying to detect.
The content trigger is *very* short (2 chars) at start of packet and it looks at all traffic except port 139.
Anyway it is generating many thousands of alerts an hour on our network. Some TCP sessions are
alerting several times a second.
I'm about to disable the rule.
This should give folk some idea of the size of the problem on our network
