Re: Make Snort See SPAN

["Jefferson, Shawn" <Shawn.Jefferson () bcferries com>]

All that should be required is to call snort with -i ethX for it to see the SPAN port traffic (replace X with the 
number of the Ethernet adapter plugged into the SPAN port.

Subject: [Snort-users] Make Snort See SPAN

Hi,

Snort newbie here. I have snort 2.8.4.1 running on FBSD 7.1. There are two Ethernet interfaces, one has an IP and is 
used to SSH into the box, the other is a SPAN port going to an Cisco 6509. Everything works OK, except I don't know how 
to make Snort monitor the SPAN. Right now, snort only sees traffic on the Ethernet interface. The SPAN is working. I've 
confirmed that with tcpdump. Any suggestions? I've Googled, but nothing came up.

Thanks
