How can I find the process which uses most bandwidth on a Linux PC?
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
and after it starts, press
't' and now you need to pause by pressing
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.
