I recently got my hands on a couple of gigabyte servers. These machines came preinstalled with Ubuntu 20.04. Credentials for a OS local user account were on a sticker on the machines. However there was no indication of what the BMC credentials were. According to this document, there should be default credentials that we can use on the motherboard, however, they were not working.

These machines came with Ubuntu 20.04 on them, and did not have ipmitool installed.

$ sudo apt install ipmitool --fix-missing

Once installed we need to determine what BMC users exist.

$ sudo ipmitool user list 1

In the output below you can see that there is one user – “admin” – identified as ID #2

Now lets reset the password for “admin”.

$ sudo ipmitool user set password 2

We are then prompted to create a new password.

We should now be able to load the BMC web interface and login with our new credentials
