Basically you need to put the ethernet MAC address of the new card in the HWADDR= line of the appropriate ifcfg-eth? file. Assuming you are talking about Centos 5.x, the devices are renamed to match these files based on the hwaddr entries even if they were detected in a different order. But some conditions that I don't understand may trigger all of these files to be renamed with a .bak extension at bootup and new default dhcp configs created instead. This is never fun when your only access to the machine is through the network. -- Les Mikesell lesmikesell@xxxxxxxxx _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
