One of my CenTOS systems recently booted with the following error:
"Bringing up interface eth0: Device eth0 has difference MAC address than expected. ignoring."
When I run ifconfig -a there's no entry for eth0 and I'm reasonably certain that the static HWADDR entry in /etc/sysconfig/network-scripts/ifcfg-eth0 is incorrect.
Are there alternate ways for definitively determining what the correct MAC addresses are via the command-line? I was wondering if perhaps lspci could help? I don't have hwinfo available.
