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:

IP address of gateway to impersonate
MAC address of gateway to impersonate
IP address of victim host

-S host_mac MAC address of victim host

OPTIONS

Display this message
Device to listen on
Write captured data to file
Dump the packet in hex and ascii
