tcptrack is a sniffer which displays information about TCP connections it 
sees on a network interface. It passively watches for connections on the 
network interface, keeps track of their state and displays a list of 
connections in a manner similar to the unix 'top' command. It displays 
source and destination addresses and ports, connection state, idle time, 
and bandwidth usage.
