I have a working Fedora 12 system which is working as a Domain Host on the built-in eth0 interface. I need to have a second interface for some in-house requirements. Every time I insert the add-in card the system redefines my interfaces as eth0 (which is the new card) and eth1_rename thus having the devices pointed to the wrong MAC address! I have gone through system-config-network about four times and no matter how I attempt to change the names and the MAC addresses the system stubbornly returns to the status quo. What .conf file or files do I have to manually vi to fix this? Any ideas? I did this same thing in my RHEL 4 ES box and had no problems at all.
