iftop - displays bandwidth usage information on an network interface

Description: displays bandwidth usage information on an network interface
 iftop does for network usage what top(1) does for CPU usage. It listens to
 network traffic on a named interface and displays a table of current bandwidth
 usage by pairs of hosts. Handy for answering the question "Why is my Internet
 link so slow?".

And this is what it looks like - fixed font required:-
