VERY nice hint - jotted away for future :) That should hopefully solve the OP's problem. If not, the next step I would personally take is to: 1) determine which ifnames are which type 2) drop into a terminal and use ip (or ifconfig still?) to manually configure each eth dev, one by one, with a static address, and see if ping works from another host; if not work, then "ifconfig down" or "ip link set $DEVNAME down" and try the next one... This way also means that specific commands are either failing or succeeding - I know it's lower level, but can make debugging ones problem a little easier from my oh-so-incredibly-humble experiences :) Good luck,
