Need help with random abnormal usage of network!

**christopherryan** · August 20th, 2013

I am brand new to using Ubuntu and am currently a variant called PinguyOS(12.04).
I have been having some troubles with my networking usage. As you can see in the picture it is very high. This is happening
when my computer is idle even. I have no program running or any background programs as far as I know of. Also, I have
just updated my whole system thinking that would help but it did not. I am not doing anything as far as P2P goes.
This is not the first time this has started happening.
Any help is appreciated!

Hay,

There are SO many options.. Google seems to think so anyway..

Code:

netstat -p

Code:

iftop

Code:

nethogs

This seems to be the most basic and pure solution, run with:

Code:

sudo nethogs $interface

Use iftop to locate the TCP port on your machine that is receiving the most traffic. Then use sudo netstat -tup to locate the process "owning" that port.

That's the process you're looking for.

PS: Should work for UDP too.

ETC...

Cheers
