Locked the server, how to change settings with terminal ?

dboris · June 12, 2022

Hello,
I have a remote server at a friend's place.
I originally tried to give a VM access to more ports.
I think I just had to assign the main interface to the VM other than the virtual bridge.

Instead of doing that, I edited the bonding members in the networking settings.

Now I can not access the server via SSH or GUI.

I have a limited access to the server : only through my friend.

I'm searching how to edit this settings through the terminal, since it's my only entry point.
I'm guessing I'll just have to do that to restore the server.

Here's a screenshot to illustrate the setting I remember having changed before meeting a no-access wall.

I also include a diagnostic.

Don't hesitate to point me somewhere if It's already been discussed.
I was unable to find such informations, and I now wonder how I could edit basically any setting with command lines if I ever meet such issues later on.
I tried booting with no pluggins and no GUI ; still no SSH.

Thanks a lot in advance for the tips.
