Package iftop

Command line tool that displays bandwidth usage on an interface

http://www.ex-parrot.com/~pdw/iftop/

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 our ADSL link
so slow?".

Version: 1.0
