1st : Getting the MAC address
run /sbin/ifconfig , copy HWaddr value and figure out which network card it belongs to.
eth0 Link encap:Ethernet HWaddr 00:E0:4C:43:D8:80
2nd : Edit the conf
as root, open /etc/sysconfig/networking/devices/ifcfg-ethN (N is the number of your eth device) using your favourite text editor. Add this key into the configuration:
HWADDR=device-MAC-address3rd : Restart computer
restart the computer to apply the bind. (if you are very good in kernel modules, you can try to apply the setting without restarting)
