But could not figure out what the problem with snort.rules file which PP has created. Regards, Ashraf On Tue, Apr 23, 2013 at 4:44 PM, James Lay <jlay () slave-tothe-box net> wrote:
Let's see one of the rules, and what sdo your HOME_NET and EXTERNAL_NET look like?

There seems to be some problem with the snort.rules file which PP has created. Regards, Ashraf Security System Engineer.

Also run tcpdump against the interface you are listening from, simply tcpdump -i ethX -v Do you see any traffic? Replace ethX with your interface. ------------------------------ From: Ashraf Ali <ashrafali.ibs () gmail com> Sent: 4/22/2013 3:37 PM To: snort-users () lists sourceforge net Subject: [Snort-users] Snort 2.9.4.5 rules using pp Hi All, recently i have deployed snort in ubuntu 12.04 using Autosnort , during the installation PP asked for Oinkcode ,as i am a registered user so i have provided the same. After completion of the installation, i have seen that snort and barnyard2 services are running in Deamon mode, and in /var/log/snort folder a file with name snort.u2.1366**** is also created but empty(0 bytes). -rw-r--r-- 1 snort snort 2056 Apr 22 17:54 barnyard2.waldo *-rw------- 1 snort snort 0 Apr 22 17:54 snort.u2.136662****** there is a single rules file called snort.rules in /usr/local/snort/rules folder which has all the downloaded snort rules, and same is included in the snort.conf file. Even i have run the snort in test mode using -T , it does not shows up any problem, its working fine but not generating any logs. I have formated the server , and re-installed every thing manually this time. still the same problem. file is getting created but no logs. pls Advice.
