Unbinding MAC Addresses on Fedora
By default, Fedora binds ethernet interfaces (such as eth0) to a MAC address (specific network interface card/NIC). This is useful, because if a NIC is added, it will be assigned a new ethernet interface (instead of bumping the existing eth0 to eth1). However, this causes problems when you use a removable disk drive and move it from one computer to another.
To unbind the interace from the MAC address:
- Start the system-config-network tool (on the menus under System>Administration>Network).
- Double-click on the eth0 device.
- Select the Hardware tab and uncheck the box labeled Bind to MAC address, then click Ok.
- Select File>Save.
- Delete the file
/etc/udev/rules.d/70-persistent-net-rulesby entering this command as root:
- Reboot your system.
