Monitoring Opened TCP/IP network ports/connections in Linux

tcptrack displays the status of TCP connections that it sees on a given network interface. tcptrack monitors their state and displays information such as state, source/destination addresses and bandwidth usage in a sorted, updated list very much like the top command.

The filter expression is a standard pcap filter expression (identical to the expressions used by tcpdump) which can be used to filter down the characteristics of TCP connections that tcptrack will see.

Execute:

tcptrack -h

for help

Basic Usage:

tcptrack -i eth0
