Ubuntu Server: rename eth1 to eth0

Today I needed to change / rename network interface name ‘eth1’ to ‘eth0’, after replacing broken network card. I searched for the file ‘/etc/iftab’, and it was not there.

The solution lies in the file ‘/etc/udev/rules.d/70-persistent-net.rules’:
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0b:49:81:02:13", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

Changing NAME=”eth1″ to NAME=”eth0″ did the trick.

Tested on Ubuntu Server 9.04.
