Same thing happened to msyelf too.. On a fresh install of knoppix to HD, it runs great... (on laptop with wireless card) ... my eth0 is setup as my LAN, and works great...

Then i upgraded my packages and since, my eth0 is totally down..and i get the same message "Operation Failed" and the only way i can get anything working is if i run the knoppix-autoconfig (which basically runs pump) but my LAN card get's moved to eth1 now... ?? and i can't run "ifdown eth1" on it either.. it's kinda bizzare...

anyone else with these sort of problems?
