What is changing the Network settings from eth0 to eth1 ?

Even if you go into /etc/sysconfig/network-scripts/ifcfg-eth0 and setup
eth0, and reboot box,it will change settings to eth1.

And it is causing a unstable network.

This box only has one ethernet card in  it.

Now days, when Fedora detects a different NIC from one it knew (right or
wrong), it creates a new entry in:

This is why you get messages in dmesg and at bootup that eth0 is being
'moved' to eth1.

It is reasonably safe to remove this file, plus
/etc/sysconfig/network-scripts/ifcfg-eth? and reboot.

If you are just doing DHCP, then udev will recreate the file, put the
correct NIC into it, and set up a generic ifcfg-eth0 script.

Good luck!

Thanks for this post, it helped me a bit, but I still have nameserver
Yesterday my [only]nic in a 32 bit fc8 box blew. When I replaced it,
it insisted to be eth1 and gave me eth0 errors when booting. I did an
ifconfig 192.168.... and had eth1 up and running.
You did change the MAC address in the config, to reflect the change right?
Otherwise eth0 will go to the old MAC address even if not present, and the
next NIC found will be eth1, eth2, etc.
In the network gui, there is a "probe" button. I used that and saw it
magically change the MAC.

That should do it.
