Maybe gkrellm is reporting on traffic before the firewall drops it.


On another computer on a computer room with a hub, I sometimes see
high traffic in gkrelm, hundreds of kilobytes per second, while my
computer is doing nothing. Looking with iptraf, I see that the traffic
is from internet to another computer of the lan, a download.

I don't know if perhaps the port is set to promiscuous mode, but the
firewall is up on my lan side. It is curious.

Check /var/log/messages to see if a device was placed in promiscuous
mode. When you see traffic not destined for the device you're looking
at, it is in promiscuous mode.
