BIOS lists one device. Motherboard does not have an interface card. No fiber optic. No BNC connector. I commented out the "ghost" MAC address from udev's rules file and rebooted. It has not reappeared. However, the problem I have is that the ethernet ports don't stick in the same order. They came up in a completely different order. I now have eth0, 1, and 4. What was eth0 prior to the reboot is now ... uh ... 'rename4' according to the udev messages: udev: renamed network interface eth0 to rename2 (this is the Intel Pro 100 add-in card [e100 module]) udev: renamed network interface eth1 to eth0 (this is the SMC1255TX add-in card [tulip module]) udev: renamed network interface rename2 to eth1 udev: renamed network interface eth2 to rename4 (this is the motherboard ethernet port [VIA Rhine module]) What gives?? How can I tell it to either stop mucking with them, or to do it in the order I want it to: on-board: eth0 Intel: eth1 SMC: eth2 On Fri, Dec 28, 2012 at 12:30 PM, Dale Dellutri <daledellutri at gmail.com>wrote: > On Fri, Dec 28, 2012 at 12:56 PM, Ashley M.
