Title: OpenBMC password
Post by: atomicdog on March 13, 2022, 03:13:09 am
I'm trying to log in to the BMC on my new Talos II with the password that came in the box, but it doesn't work.

Are there instructions somewhere on setting/resetting the password? I've connected to the serial console port but don't see any obvious way in u-boot to do that.

0 (zero) and O look identically on that slip.
Have you tried all the variations?

Yeah, I've tried different variation for the characters that look ambiguous, but still no luck logging in.

Please ensure you are logging in with the "root" user, either via SSH or the Web interface.  Also note that the "1" and "I" characters can look similar on the password paperwork.

It was a lowercase L.
For some reason I thought it was an uppercase L or maybe a '1' or 'I'. The 'one' is very similar.

I'm still curious on how logging into the serial console is suppose to allow you to reset the password though. I don't see any OpenBMC documentation about it. I found this: https://docs.graphcore.ai/projects/bmc-user-guide/en/latest/serial-rescue.html ...but is it specific to graphcore processors or generic to OpenBMC?

That's for changing a password when you're already able to login, but I meant for recovering access and resetting a lost password.

As far as I know, a lost or forgotten BMC password basically requires reflashing the BMC chip. But if you're already logged into the BMC, changing it should be as simple as running
Code: [Select]
passwdand very carefully entering the new passphrase, three times. I have discovered (through my own painful experience :P) that the separate password for the boot menu (Petitboot) can more easily be reset.
