      4G8 - Packet Sniffer Over Switched Network
    ------------------------------------------------------------------------

    DETAILS

     <http://forgate.sourceforge.net> 4G8 (Forge Gate) 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.

    To run 4G8 you need to obtain the IP and MAC of the gateway, as well as
    the IP and MAC address of the target, both available by simply looking at
    the ARP table.

    4G8 requires <http://www.packetfactory.net/libnet> libnet 1.1 or greater
    as well as <http://tcpdump.org/> libpcap. It has been successfully
    compiled and tested to run on FreeBSD, NetBSD, OpenBSD and Linux.

    ADDITIONAL INFORMATION

    The tool can be downloaded from:
