Re: Disabling Rules via disablesid.conf

Also, make sure that your snort.conf is actually pointing to the file(s)
being created/edited by pulledpork. The current registered version of
bad_traffic.rules
doesn't have any rules in it, so this makes me wonder if your snort.conf
isn't pointed at the correct rule file(s).

Thanks for the heads up. I followed your troubleshooting steps and I
found the offending alert in bad_traffic.rules file. I deleted the line and
it looks like they are disabled now.

# Glad that you found the source of the issue. Just keep in mind that
manual changes to .rules files, i.e.: deleting/commenting rules, will be
overridden by the next rules update. Just a wild guess here, but from what
you said you may have these two rules in multiple .rules files, which
eventually are included in snort.conf. When running Snort, does the startup
messages indicate anything about duplicate rules? Just to further verify.


Thanks again.

I have Snort running on a few sensors around our network. We have
subscriptions for the rules and we use pulledpork to download the rules
daily.

I am not attempting to turn the rules a little bit to disable some items
that we do not need to see. I put these in disablesid.conf file and when I
run pulled pork I see:

Processing /etc/snort/disablesid.conf....
Disabled 3:21355
Disabled 3:19187
Modified 2 rules
Done

So it looks like it is disabling the rule, however I am still receiving
alerts for the rule in my database.

Any ideas?
## Some ideas to troubleshoot: 1) verify that the same sids are not
included in the enablesid.conf (lame but why not). 2) Has the order in
which PulledPork processes rules been changed?. 3) if you grep for the sids
from the snort.rules (given you reconcile rules vi PulledPork), do they
exist? 4) Are these two rules included in another .rules file (local.rules
or so)?
