So-so; not *that* close. I have some servers with two on-board NIC's whose MAC addresses end in things like fe:ab, fe:ac, fe;36, fe:37. Still.... Actually, I missed the beginning of this thread. Are there no on-board NICs? I've not seen a m/b in a long time without that; even Rasberry Pi has one. mark Mark, There is an on board nic with the m/b. Here is the mac entry of it. SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="38:60:77:ed:41:a0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" Both nic's apparently have the same chipset : "lspci | grep net" outputs : 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
