passwordless ssh root logins stopped working after testing dist-upgrade
I dist-upgraded yesterday and ssh root logins started requiring a
password. I also tweaked some other stuff and installed calibre
and miro to check them out and they came with a boatload of
dependencies so maybe there's something lurking there.
Regular user ssh logins work just fine. I decided that it would be a
good time to update my keys and redid everything very carefully from
scratch. VERY CAREFULLY checked .ssh and authorized_keys permissions,
etc. No change. This affects both user->root@localhost ssh logins
and to remote hosts. It smells like an ssh-agent problem, but then
why would regular user ssh logins continue to work?
Tia for any clues. I won't be surprised if I did something dumb...
I've got a stock /etc/ssh/sshd_config and very long time
modified ssh_config:
