'tcptrack' is a packet sniffer. It passively watches for connections on a specified network interface, tracks their states, and lists them in a manner similar to the Unix 'top' command. It displays source and destination addresses and ports, connection state, idle time, and bandwidth usage. The filter expression is a standard pcap filter expression (identical to the expressions used by tcpdump) which can filter down the characteristics of TCP connections that tcptrack will see.
