how do ifind out which processes are using network bandwidth?

[Lt Major Burns]

are there any programs i can use to see what's using up bandwidth? Activity monitor only shows that somethings using it, but not what is actually using it.

Maybe IPNetMonitorX

no that does what network utility does... it seems to be more for admin than for i want. i just want something to tell me what apps are using bandwidth, in the same way that Activity Monitor tells me what apps are using ram, or cpu. so like

FIrefox, 5.4%, 6.7kbps
Fetch, 45.5%, 35kbps
safari, 1.1%, 2kbps
etc

does anyone know of any?

How about this in Terminal;

lsof -r -i TCP -i UDP

or

sudo bash

... an administrator password - with prompted, then the <return> key, followed by ...

tcpdump

... and finally, the <return> key.

Now view the transmissions / receptions.

are there no programs that do this?
