[Resolved] Random Mac Address on Start

[Oogbored]

Mentioned this in an earlier resolved thread, the MAC address on my Go Flex Home changes on every reboot. My router sees this as a new device and issues it a new IP, which throws off network mapping for all the machines in the homegroup. I can lock it to static through the router, but only with a static Mac. Where does this build of ARCH store the MAC information?

Any ideas or posts related to this previously that I'm not finding in search?

Locked into a static ip through arch configuration. Still having random mac assignments.

Did you check to make sure the UBoot MAC address variable, ethaddr, is set? I am not sure what happens if it is unset, but it definitely seems like something that might cause issues if left unset.

I haven't known where to look for it, but I've other issues with it at the moment. System didn't like a configuration tweak I was trying and semi-bricked. I'd use my flash drive back up on it, but my roommate nabbed it and wiped it to put files on. So I get to load up a new one when I have the time. Joys of a Linux noob.

I'll definitely look there when things are back to normal.

If you have a serial connection and can access the UBoot environment directly, the command is "printenv" and look for the ethaddr variable. If you are able to boot back into a Arch Linux ARM environment, make sure you have the uboot-env package installed, and run "fw_printenv", also look for the ethaddr variable.

I ran a test where in the UBoot environment I cleared/unset the ethaddr variable (it looks like you cannot set or unset the variable with fw_setenv) and rebooted a few times. Each time I rebooted, I got a different MAC address. They all started with 02:50:43. So, my guess is somehow your ethaddr variable got unset.

Thanks, I'll check into it when I get the time, I'm guessing its the cause of the issue too, but I've got the bigger issue of unbricking and getting the time to do so, before I get there.
