These instructions are written for Fedora 12 and 13 but should apply to earlier Fedora releases. Fedora 15 utilizes a new persistent naming scheme, and interfaces may be named differently than in previous releases.
These instructions are written for Fedora 12 and 13 but should apply to earlier Fedora releases. Fedora 15 utilizes a new persistent naming scheme, and interfaces may be named differently than in previous releases.
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:rm /etc/udev/rules.d/70-persistent-net.rules - Reboot your system.
