NAME

       4g8 — Packet Capture and Interception for Switched Networks

SYNOPSIS

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

DESCRIPTION

       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

OPTIONS

       -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
