remove old eth0 interface config.

[JPMallory]

I've a fedora 8 box whose motherboard has croaked. I pulled the harddrive, and placed in a new machine. The OS boots fine, but instead of using eth0 and eth1 for the network interfaces, it's now using eth2 and eth3, and claims that eth0 and eth1 are not present.

Where do I remove the config for eth0 and eth1 so that the box will assign them to the currently network cards?

I've tried removing the ifcfg-eth* but that doesn't seem to fix the issue.

The problem was in: /etc/udev/rules.d/70-persistent-net.rules

It still contained configuration for the old network cards.

Thanks for coming back and giving the solution. (I ran into something similar recently, with cloned virtual machines.

The persistent-net-rules will keep the hardware address for the cards, and it has to be changed to the new hardware (MAC) address.
