[ale] Getting root ssh key to work (was Re: [ot] Xmpp, ejabberd question)

[Tim Watts]

OK, I did an ssh-keygen for root and managed to copy its id_rsa.pub to
$host:/root/.ssh.  (I have "PasswordAuthentication no" in my sshd_config
so can't use ssh-copy-id.)  On the target host it shows this:

$ sudo ls -l /root/.ssh/
total 8
-rw-r--r-- 1 root root 396 2012-01-13 14:36 id_rsa.pub
-rw-r--r-- 1 root root 884 2010-11-28 13:36 known_hosts

On my local machine I have this:

# ls -l /root/.ssh
total 12
-rw------- 1 root root 1743 2012-01-13 14:25 id_rsa
-rw-r--r-- 1 root root  396 2012-01-13 14:25 id_rsa.pub
-rw-r--r-- 1 root root  884 2009-11-11 06:17 known_hosts

The timestamp difference is due to copying it to my home before scp-ing
it to the target host.

And yet:

# ssh timtw at blueberry
Permission denied (publickey).
# ssh blueberry
Permission denied (publickey).

My sshd_config has "PermitRootLogin yes".  What else could I be missing?
