Packet Capture and Interception for Switched Networks
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 |
