sure, but in my case the Iface is configured with Mpd. I'm trying to 
catch that case, where a user with a static-IP (provided by the RADIUS 
server) was logged in twice. I tried to catch the return value from 
ifconfig, but since it's allowed to have multiple ifaces with the same 
ip, ifconfig succeeds.

... so, it looks like I have to find another way :-(

thanx,
