NetHogs

NetHogs is a lightweight Linux terminal-based tool that monitors bandwidth usage, then groups it by process, so you can see which PIDs are using the most bandwidth, and if necessary, kill them with System Monitor.

To install NetHogs on Ubuntu (tested on 9.10 Karmic), you can either use Synaptic or simply apt-get, like so:

sudo apt-get install nethogs

To run NetHogs, simply feed it the internet connection you wish to examine, and sit back.

sudo nethogs eth0

For more information and the full list of options, visit the NetHogs man page.

man nethogs
