I have a machine with 2 network cards. Installing centos 5 on it.
I set up both cards with static IP addresses. activate on boot etc...
One is e1000 Intel the other is onboard forcedeth (nvidia).
After I reboot the forcedeth ifcfg-eth1 file is changed to DHCP.
I use netconfig -d eth1 to set it back up and reboot again and the changes back to DHCP.
Only thing to add here is the network card does work, however I get a dmesg output that eth1 has an invalid MAC address.
Is that invalid MAC address changing my setup? I dont think it should. granted I'm still looking at finding a way to reset he MAC address or something but I dont think the ifcfg-eth files should be modified.
This seems like a bug- that is the reason for the post.
Great work with centos 5!

Asus mainboard?

The random address is different from the one which is in ifcfg-eth* from installation.

Yes. Googling around hints at this being a BIOS bug. Also see http://bugs.centos.org/view.php?id=1949.

Can you fix this by removing the: HWADDR= line from the ifcfg-eth* files? Most of my machines have swappable drive carriers and I routinely swap them and clone machines by dd'ing the raw disks. If I remove the HWADDR entry I can assign the IP addresses when building the disks and have it come up correctly when the disk is installed in some remote machine. I suppose someday this will break when I'm not looking, but it has saved me a lot of trouble over the last several years. Now if the kernels would just be consistent about the order they probe the devices and assign the eth* names....

I was going to suggest trying that too....
Agreed! I generally do that too unless I'm in an ethernet bonding situation where I want to make sure I specify the correct NIC as primary. Most of the time, it really doesn't matter.

I would think so. If udev doesn't want to have a say in that ...
