[Snort-sigs] Disabled rule still alerting

How do you suppress it?


It is a shared-object dynamic rule that does not have a gen-id/sig-id in gen-msg.map.


I’m following the recommended procedure by putting it in the ‘disablesid.conf’ file when running pulledpork.  I even tried the ‘-E’ option so only enabled rules get written to the outfile (so the rule doesn’t even exist anymore) and I STILL get the alerts!!!

Suppress the rule, don't comment it out.

I’m getting TONS of hits for the following:


3:21355 (BAD-TRAFFIC potential dns cache poisoning attempt - mismatched txid)


Here is my disablesid.conf:














Here is an excerpt from my ‘snort.rules’ showing it is indeed commented-out:


# alert udp $EXTERNAL_NET 53 -> $HOME_NET any (msg:"BAD-TRAFFIC potential dns cache poisoning attempt - mismatched txid"; sid:21355; gid:3; rev:2; classtype:attempted-recon; reference:cve,2010-1690; reference:url,technet.microsoft.com/en-us/security/bulletin/MS10-024; metadata: engine shared, soid 3|21355;)


Yet, I continue to get thousands of alerts.  Can anybody help me figure out how to turn these off?
