I am new to Snort and just managed to set up v. 2.9.2 on Ubuntu 10.04. I have now created an own simple rule, just to try out my setup. It looks like this:
alert tcp any any -> any any (content:"www.uid11.local""; msg:"First rule test"; sid: 132321;)
And I run snort like this:
/usr/local/lib/snort/bin/snort -u snort -g snort -c /usr/local/lib/snort/etc/snort.conf -i eth1
But it doesn't work! Nothing happens. After I've hit CTRL+C I see that it has controlled xxx packets, but nothing more, no drops, alerts etc.
My server running Snort got two interfaces, eth0 and eth1. eth0 got IP 10.10.10.3 and eth1 got 192.168.1.1.
I got a webserver on the network 10.10.10.0-net with IP 10.10.10.1. And I have a client on 192.168.1.0-net with IP 192.168.1.10.
To make it possible for my client to reach the webserver I've activated IPv4-forwarding in /etc/sysctl.conf on the server running Snort.
So the client got 192.168.1.1 as it's default gateway, and the webserver 10.10.10.3.
So my topology looks like this:
10.10.10.1 10.10.10.3 192.168.1.1 192.168.1.10
What else do you need to know? I need your help to figure out what my noobish head don't understand.
Thank you in advance!
