View source for Unbinding MAC Addresses on Fedora

[[Category:Fedora]][[Category:OPS235]][[Category:OPS335]]{{Admon/note|Fedora 12/13/14|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).<br />[[Image:Ops235-network-mac-1.png]]
# Double-click on the '''eth0''' device.<br />[[Image:Ops235-network-mac-2.png]]
# Select the '''Hardware''' tab and uncheck the box labeled '''Bind to MAC address''', then click '''Ok'''.<br />[[Image:Ops235-network-mac-3.png]]
# Select File>Save.
# '''Delete the file <code>/etc/udev/rules.d/70-persistent-net-rules</code> by entering this command as root:''' <code>rm /etc/udev/rules.d/70-persistent-net.rules</code>
# Reboot your system.
