Howto: installing iftop

display bandwidth usage on an 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 our ADSL link so slow?".

I find Vnstats "prettier" than this (: but then again i also use cacti to graph my logs for me.

vnstats calculates the totals while iftop show you bandwidth consumptions live.
