After cloning one harddrive to another system, the adapter is no longer eth0, sadly it is stuck on eth3.
Nothing seems to compel or force the adapter to be it's proper designation of eth0. I have gone through the rounds of deleting the adapter and creating a fresh one in the GUI. I have invested an hour in pouring over google and this forum.
I did this:
mv /etc/sysconfig/network-scripts/ifcfg-eth3 /etc/sysconfig/network-scripts/ifcfg-eth0
No dice, it only created another phantom adapter in the "Network Configuration" window.
When I used the "Network Configuration" window to delete the phantom adapter, so that only the proper of eth0 remained, it slapped me with the big wet fish by not coming on to the network after reboot.
Now someone on-site must run to the server closet and delete the adapter, then reestablish it, but it will still be the unwanted "eth0"
How to force the adapter to become its necesary eth0 ?
