This directive is useful for machines with multiple NICs to ensure that the interfaces are assigned the correct device names regardless of the configured load order for each NIC's module. This directive should /not/ be used in conjunction with MACADDR. You can get the mac address from running ifconfig. The HWADDR setting goes in the /etc/sysconfig/network-scripts/ifcfg-eth0 (and ifcfg-eth1) files. (the setting either doesn't exist, or may be transposed and causing your problems) -Shawn
