Re: snort not catching any packets

[Robert W <rwawrig () yahoo com>]

I've found the issue, if anyone is wondering why snort is not capturing anything even when are no errors and all looks 
ok.
The rules which I've downloaded from snort.org have most of the alerts commented within the rule files. After I've 
enabled all the alerts from scan.rules, my scans started to get logged by snort.

cheers
Robert

Subject: [Snort-users] snort not catching any packets
 


Hi,

I'm new to snort, so probably I'm missing something obvious..
I'm running snort with output unified2 and barnyard2 which is saving to mysql, and snorby as front-end.
Snort is not catching anything with only the rules enabled (snort.conf -> Step #7: Customize your rule set). The 
"merged.log" unified2 file stays at 0 bytes.
If I enable decoder and preprocessor event rules (#Step 8) then it starts catching events, but are coming up as Snort 
Alert [xxx:y:z]. The alerts are not mapped to names.

Also barnyard is giving this message:
[Event: 1] with [gid: 120] [sid: 3] [rev: 1] [classification: 2] [priority: 3]    was not found in barnyard2 signature 
cache, this could lead to display inconsistency. To prevent this warning, make sure that your sid-msg.map and 
gen-msg.map file are up to date with the snort process logging to the spool file.

I've checked again and again all the conf files and the variables, all point to the correct sid-msg.map and 
gen-msg.map. 


Any idea what may be wrong?

Thanks
Robert
