Problem:

How can I change the network device name back to eth0?

Details:

In Fedora 19 the operating system no longer uses the traditional device names for the Ethernet controllers.

Solution:

To revert to the traditional naming perform the following steps. First, remove the biosdevname package:

# yum remove biosdevname

Next, rename the network configuration file. For example:

# rename em1 eth0 /etc/sysconfig/network-scripts/ifcfg-em1

Finally, edit the configuration file and change the device name. For example:

DEVICE="em1" -> DEVICE="eth0"
NAME="em1" -> NAME="eth0"

Reboot the system for the changes to take effect.
