Hi All,

Just realized that I have two rules in my local.rules file with same sid,
and snort works just fine!!
I always had in my head that sids should have to be unique, but today when
I was going through the local.rules file, I realized that someone from our
team had created a new rule and assigned it a same sid that a previous rule
I couldn't catch it before because snort was running just fine without any
complains on duplicate sids.

Have I missed this change in the current (or 2.9 version) of snort or is it
something else?

Quick points: I have local.rules enabled in snort.conf and pulled pork is
not modifying anything regarding local rules so they should get loaded as
it is, and above all I am getting alerts for one of the rules having
duplicate sid, but no alerts for the other rule having same sid.

Snort version -
barnyard version - 2-1.9
pulledpork - 0.7.0
