Answer by d34dh0r53 for eth0 and eth1 both assigned same IP on boot

Try adding:

HWADDR='00:18:4f:8d:85:4a'

to /etc/sysconfig/network-scripts/ifcfg-eth0. You may also want to create an ifcfg-eth1 that contains something like this:

DEVICE='eth1'BOOTPROTO='none'HWADDR='00:18:4f:8d:85:4b'USERCONTROL='no'ONBOOT='yes'

At least on RHEL that will just bring up the interface with no IP configuration, and the networking init scripts look similar on SuSE 11. The other solution regarding SuSE networking configuration is to clear out the 70-persistent-net.rules with something like:

cat < /dev/null > /etc/udev/rules.d/70-persistent-net.rules

That will clear the udev rules and tell init to use the ifcfg-eth* files for interface identification.
