[Snort-users] Local Rule Error

I found one of my mistakes.  I had a local rules path in the config file twice so that explains why snort was giving me the error.  Now it runs with no errors but is not logging my packet that I know has the "chmod" text string.  Do I need to include some wildcard placeholders like "*chmod*"?  Does this rule look to have the required  components?

alert tcp $EXTERNAL_NET any -> $HOME_NET any (msg:"LOCAL RULE-chmod command attempt"; content:"chmod"; sid:500001; rev:1;)

Thanks again.

Thanks for the reply.  I added the two extra zeros as you suggested and am still getting the error.  I'm using the community rules and don't have any other local rules.  I've attached a screenshot so you can see the error.  There must be something else in the rule that is confusing snort.

what other rules do you have installed and configured? it appears, based on what you've written, that you have other rules installed and configured for use...

try adding a few more zeros to your local base SID range... i use 100000000 to start my local rules specifically to get their SIDs up and away from the others currently available by distribution...

yours: 5000001
mine : 100000000
