4g8 1.0                                            August 2007                                            4g8(1)

       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.
