This is not possible with the current AFPacket DAQ module since I never really thought to do that, but it could be modified to do so (check if an instance for that interface already exists when opening each interface and reuse it instead of trying to reopen and failing). You may be able to do something like that with IPTables and the NFQ DAQ module, but I couldn't say for sure.

What if I only have single interface card "eth0" ?can I redirect/pair the traffic to itself (i know it is kind of silly statement)something like this: snort -Q --daq afpacket -i eth0:eth0 -c snort.conf --- On *Mon, 5/16/11, Michael Altizer /<xiche () verizon net>/* wrote: From: Michael Altizer <xiche () verizon net> Subject: Re: [Snort-users] Snort in IPS mode To: snort-users () lists sourceforge net Received: Monday, May 16, 2011, 6:27 AM On 05/15/2011 08:09 PM, turki wrote:Hi, I am new to snort, so i need help here. I am trying to run snort in inline mode with the following command: snort -Q --daq afpacket -i eth0 -c snort.conf but snort initialization keeps failing with error message: afpacket DAQ configured to inline. ERROR: Can't initialize DAQ afpacket (-1) - afpacket_daq_initialize: Invalid interface specification: 'eth0'! Fatal Error, Quitting..In order to have an inline deployment you need at least one pair of interfaces for the traffic to flow through. To that end, you need to specify a second interface for AFPacket to use to complete the bridge. For example: snort -Q --daq afpacket -i eth0:eth1 -c snort.conf or (two inline pairs): snort -Q --daq afpacket -i eth0:eth1::eth2:eth3 -c snort.conf
