The box doing the monitoring needs to be able to see the traffic. If you
have a hub (unlikely these days) then you can watch from any of the machines.
Switches and routers will hide most of the traffic from nodes that aren't
supposed to need to see it.

If watching from the router or routing stuff through your fedora box is
a pain, you could start by unplugging network cables and notice when things
get better.

If there is almost no traffic normally, and your nics have leds, you might
be able to see which machine has a constantly flashing led on it's nic.
