Snort starts as a service - "service snort start or restart or stop" are the
options there.  In order to shift your sensor to eth1 you need to modify the
snort startup script in the /etc/init.d directory to change the default eth0
to eth1

That is my another question. When I run "snort start", I got prompt:
        Starting snort service:

What should I enter? I know, there are lot of reading, but I just start.


Thank you,

You will need to change the interface in your init script then restart

Esteban,

Thank you to answer my mail. I spent few hours, finally fixed the
problem.
When I use "tcpdump -i eth1", I can see the traffic send from switch.
I have another problem. Snort/BASE only capture eth0 traffic, which I
use for the monitor connection. I can not see traffic on eth1.

How can I sniff eth1 traffic to Snort? I checked the snort.conf, I did
not find anywhere for it.

Thank you for all of your help,

--Greta

        Hi,

        I am a new user on this list. I have a simple problem, and hope
to
get a
        help. I just installed Snort 2.6 on Centos. I follow the
document to
bring
        eth1 up (eth0 has IP to connect to the Internal network).  But I
can
not
        see any traffic on eth1 (tcpdump -i eth1). I checked the switch,
I
can see
        traffice on the interface (# sh interface f0/8):

            monitor session 1 source interface Fa0/2
            monitor session 1 destination interface Fa0/8

             270471 packets output, 65224246 bytes, 0 underruns

        Did I missing anything at here? Could some one help me?

        Thank you,

        --Greta
