4g8 1.0-3.2 (ppc64el binary) in ubuntu cosmic

 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.
