How to find process which uses most bandwidth

Question

How can I find the process which uses most bandwidth on a Linux PC?

With iftop it's possible to find which connections produce most bandwidth, but how to find the process?

nethogs is something similar, but shows also the process (http://nethogs.sourceforge.net/)

little clumsy solution, but

start

iftop -nNP

and after it starts, press 't' and now you need to pause by pressing 'P' (shift+p). copy the desired 'IP:port' from 2nd column and start as super-user

netstat -tnp | grep "<paste_IP:port_here>"

and at the last field of the output you should see PID/program. hope this help.
