Disclaimer, I am not nor ever have been a professional admin and I've not dealt with a computer with multiple ethernet NICs. I seem to recall that on initial installation with some prior releases that udev would write a rules file that mapped a hardware address to an interface name. I hit this a couple of times when moving a disk into another machine and found that firewall rules didn't work since the NIC was now eth1 instead of eth0. A simple edit of the rules file to comment out the eth0 stanza and renaming eth1 to eth0 and restarting networking resolved the issue, as I recall. It may have taken a system restart instead, I don't remember exactly. I'm unsure why the udev approach wasn't good enough, but here we are. On this desktop I restored the old naming convention for various reasons while the laptop has the new convention. Both work, but the predictable names are a bit of random noise to my eyes and require a moment's parsing. - Nate -- "The optimist proclaims that we live in the best of all possible worlds.
