iftop 1.0 Pre4

This Open Source CLI tool can display bandwidth usage for a given network interface
iftop is an open source command-line software designed to display network traffic usage on your Linux-based operating system. It does exactly what the top utility does for CPU usage.

How iftop works? Simple, it listens to the network traffic on a specified network interface and displays real-time bandwidth usage information, listed in a table sorted by pairs of hosts.

iftop is usually used to see why your network connection is so slow. Besides the source archive, the software is also distributed as binary packages for both Linux (SuSE, Red Hat) and Solaris operating systems.
