HI Dean,

You need to edit your snort.conf file and include the new rule which you
have created.  Only then it would capture it.

Try to create the file under local.rule file under the rules directory as
it is already included in the snort.conf

Let me konw if that works.

Hello,****

** **

I’m running Snort 2.8.5.2 (Build 121) on Ubuntu 11.10 with
3.0.0-16-generic kernel.****

** **

I have written the following rule called */etc/snort/rules/password.rules*
:****

** **

alert tcp any any <> 192.168.1.110 any (content:”password”; msg:”Potential
Password Violation”; sid: 11995522;)****

** **

My snort command is:****

snort -dev -c /etc/snort/snort.conf -l /etc/snort/log2 -K ascii****

** **

I then transfer a file with the word “password” in it from the Linux
system to a Windows system using Samba. The packets are captured as
evidenced by the terminal display. The Windows system successfully
authenticates to Samba and the file can be viewed on the Windows system.**
**

** **

PROBLEM: No directories are created in the /etc/snort/log2 directories.
Only an empty “Alert” file appears.****

** **

If I run a command like:****

** **

snort –dev –l /etc/snort/log2 –K ascii****

** **

I get normal logging directories with IP address directory names etc.****

** **

This command also results in nothing in /etc/snort/log2 except the empty
alert file.****

snort –dev –c /etc/snort/rules/password.rules –l /etc/snort/log2 –K ascii*
***

** **

REQUEST: Any help I can get to allow proper logging when using the –c
option would be much appreciated.****

** **

Thanks,****

** **

Dean****
