I'm sorry, i made a mistake, i was referring to the LibreELEC addon (without s :D). The one that allow to configure SSH, Samba, Wireless and so on.
In this case, i was trying to remotely disable the SSH password login since i've enabled the key auth.
I'm outside home and don't have access to the GUI.
But in general i was curious if the settings managed by the LibreELEC setting addon can be accessed only by the gui or if there is config file somewhere.
I've tried to search in the filesystem but didn't saw anything relevant.
By the way, excellent work, LibreELEC is really fast and very stable, i'm very satisfied with it!
