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,
