Re: Snort in IPS mode

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

            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
