I installed Oinkmaster to update the Snort rules at 7:00am everyday. And =
it works fine. But the Snort doesn't work after I restart it (snort). =
And it is caused by the duplicated SID. Could you please help me on =
these 2 questiones? Thanks in advance!!
1. How does Oinkmaster check for the update rules? It compares the SID =
or Content of a rule?
2. How does Oinkmaster handle the duplicated SID? or I need to fix it =

I'm not sure I understand what you mean. Snort shouldn't have any
problems starting even if the sigs contains duplicate SIDs. Perhaps you

see the Changelog for Oinkmaster 1.1 ("Better handlig of duplicate
rules"). This is not needed unless the downloaded signatures are broken
and actually contains dups though, so I don't think it's related to
