I think I did a really bad thing. I tried for several hours to get the SSH login without password working – it would not work for some reason. I changed the permissions of my home folder, added the authorized_keys
file etc. – I read all the 100 tutorials.
I thought, hey, maybe it is just because the default PasswordAuthentication no
option is not working. So I added it – et voila, now I can't log in anymore.
Any idea what to do? Reset the whole NAS?
