ntop is a network traffic probe
that shows the network usage, similar to what the popular top
Unix command does. ntop is based on libpcap and it has been written
in a portable way in order to virtually run on every Unix platform
- including the Cobalt RaQs.
ntop users can use a a web browser (e.g. Internet Explorer, Mozilla,
Netscape) to navigate through ntop (that acts as a web server)
traffic information and get a dump of the network status.
See some screenshots of the web interface:

Or see it in action on a RaQ4 here.
