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.
command to run tcptrack would be: ” sudo tcptrack -i eth1 ” . Here is the interface tcptrack will be listening too. To see which interface is listening to the internet, typ ” ifconfig ” on the console.
