[SOLVED] Mystery NICs
I have a Fedora system that I just changed the mother board on. The old NICs were eth0 and eth1. Now I have only one NIC that shows up as eth3. The problem is no matter what I do, eth0 and eth1 will not go away and their configs conflict with eth3. I removed Network Manager via yum. I deleted the ifcfg-eth0/1 files from /etc/sysconfig/network-scripts and /etc/sysconfig/networking/default and profiles. In all of these locations the ifcfg-eth0/1 files keep reappearing after a reboot. I am at a loss at this point how to get rid of these non-existant NICs. Ideas?

This is udev what does it. Remove obsolete entries from /etc/udev/rules.d/70-persistent-net.rules (location may vary depending on distro).
