Hi All! Thanks for your answers. I think it is really the du binary which causes the message, and yea, /proc doesnt really exist on the disk, so "du" is quite pointless anyways. Well I was just worried about some user on that box r00ted it (a lot of ppl from #hacktech have shell on that box, hehe...). Okies Thankie very much again and have a nice day all Cheers Christian Burri
