How are you starting snort?

There is a debug option if you use --daq-var. 

See the daq readme.

afpacket functions similar to the pcap DAQ but with better performance:

    ./snort --daq afpacket -i <device>
            [--daq-var buffer_size_mb=<#MB>]
            [--daq-var debug]

Subject: [Snort-users] Bridging issue inline

Hello,
I’m having trouble with the bridging for Snort inline use on a VMware ESXi host.  This is using afpacket inline.

Is there a way to debug the bridge? I have tried all kinds of troubleshooting and command line testing. I get snort up, 
running in inline mode, but no traffic is seen except what hits one side of the bridge. So, again:

How do you debug, view that the bridge is set up?
Do the DAQ modules need bridging enabled in the kernel, or is it a “software” bridge?

Thanks
Bill
