Snort failing to load rules
-
Have been getting this error since last couple of days. Tried updating my 2.4 snapshot and reinstalled snort on a fresh 2.4 install. Getting the same error.
Can anyone help me find that 20835 rule which is causing the issue.

Thanks. Appreciate the quick response.
Not sure but it has something to do with "Snort OPENAPPI Rules". The moment I un-select all the rules under that last column Snort starts but if I enable even one single rule there ..snort fails to load with the same error I posted above.
-
Well, I'm using Suricata (but the rules are the same). There's no support for OpenAppID rules there, so… cannot help. Probably better asked in IPS/IDS forum, don't think it's related to 2.4 snapshots.
-
Hmm. makes me think.. should I move to Suricata? Would you recommend it?
-
Well, you'd definitely not hit similar issues there, since broken/unsupported rules are just skipped. Otherwise, pretty happy with that, multithreading definitely helps.
-
How about the long list of false positives that I have identified in Snort. Will I have to start from scratch? It took me well over a year to assemble that list.
-
Hmmm well, I'm using SID Mgmt - disablesid.conf for any FPs. If you are using something else, not sure… but I guess getting those out of config.xml should be doable as well.
-
Yeah I use the same but I had to suppress the FPs one by one to ensure I am not suppressing the wrong ones. Took some good time. Can I just transfer the Snort FPs to Suricata?
-
Yeah definitely, just save the file and paste back to Suricata. The rulesets are the same, so are the SIDs.

Awesome! Thanks bud. :D
