       4g8 - Packet Capture and Interception for Switched Networks


       4g8 -i <device> -g <gw_ip> -G <gw_mac> -s <host_ip> -S <host_mac> [-w file] [-Xh]


       4G8  allows  you  to  capture  traffic from a third party in a switched environment at the
       expense of a slight increase in latency to that third  party  host.  Utilizing  ARP  cache
       poisoning,  packet capture and packet reconstruction techniques, 4G8 works with nearly all
       TCP, ICMP and UDP IPv4 traffic flows.

   Required parameters:
       -g gw_ip
              IP address of gateway to impersonate

       -G gw_mac
              MAC address of gateway to impersonate

       -s host_ip
              IP address of victim host

       -S host_mac MAC address of victim host


       -h     Display this message

       -i device
              Device to listen on

       -w file
              Write captured data to file

       -X     Dump the packet in hex and ascii
