Snort and Backdoor Rules not working
Ruleset was updated yesterday and I noticed Snort wasnt blocking spyware from newegg.com anymore, looked in the logs and confirmed snort showed up as not starting successfully, promiscuous mode disabled, and some other complaint about backdoor rules
Sep-13-2007.5:17:18 PM.Daemon.Error.10.33.40.1.UDP.Sep 13 17:17:21 snort: FATAL ERROR: Unable to open rules file: /usr/local/etc/snort/rules/backdoor.rules or /usr/local/etc/snort//usr/local/etc/snort/rules/backdoor.rules….............
Unchecked this rule and snort is working again, can anyone else confirm this.
Using ac performance method with 2 gigs of RAM/full install on white box
Ok, tracked it all down to Backdoor rules, Netbios, and Misc. rules. These 3 categories are not allowing Snort to initialize. Are any of these 3 problematic for anyone else or is it something within my own setup that causes this?
I have all other rules enabled and snort is successfully working, alerting and blocking.
Latest snort update 9/11/07

Have had the issue with only the Netbios rules myself. As soon as I check it and save snort crashes and won't restart.

the following rules are not working here:
pfsense in ac mode
in lowmem mode snort works fine
I got Netbios to work if I disable Exploit and Chat. Rule Categories are so finicky with Snort.
Just noticed too that the recent update 11/6/07 doesnt reflect my own ruleset when i compare it to the changelog. For example SPYWARE-PUT Adware adblaster 2.0 runtime detection is not listed in the Deleted category. According to the 11/6 changelog this rule was moved to Deleted but my ruleset still shows the rule in Spyware-Put. I am a Premium member and I'm referring to the 2.6 changelog.
