Find mac for eth0 windows

broken image

Where can I definitively confirm what the system sees at the MAC address? ifconfig -a shows the 'incorrect' one. In fact, if I use the MAC address that shows up in the onboard administrator and try to hardcode it to the nic (under /etc/sysconfig/network-script/ifcfg-eth0), I get an error:ĭevice eth0 has different MAC address than expected. For some reason CentOS thinks the mac address for ETH0 is something (18:a9:05:71:xx:xc) but I'm not able to find that MAC at all on the on-board administrator.

I've got a HP Proliant 460c blade server running CentOS 5.x.
