4g8 (1)

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
