Just tested "rng-tools": they also work.

Comming back to the original issue: I tested ifplugd - which turned out to be not very reliable, but worked at least some hours. Now I tested "netplugd". The result is not verry promising: eudev logged the plug-event immediately, but netplugd sometimes took a break for 5 minutes ore more to detect that the cable was plugged in.

Is there a deeper reason why eth0 plug/unplug events cannot be handled by eudev (any more)?
