Are you trying to log in as root, or as a user using key pairs? I
would have to double check, but I don't think the default sshd
configuration allows root logins. I have "PermitRootLogin no" in my
config file. It needs to be "PermitRootLogin without-password"
instead. (without-password prevents root from logging in using a
password, but will allow it using a key pair.)

PermitRootLogin
   Specifies whether root can log in using ssh(1).  The argument
   must be ``yes'', ``without-password'', ``forced-commands-only''
   or ``no''.  The default is ``yes''.

   If this option is set to ``without-password'' password authenti-
   cation is disabled for root.

   If this option is set to ``forced-commands-only'' root login with
   public key authentication will be allowed, but only if the
   command option has been specified (which may be useful for taking
   remote backups even if root login is normally not allowed).  All
   other authentication methods are disabled for root.

   If this option is set to ``no'' root is not allowed to log in.

I think that is the way to keep it. I log in as a trusted user and then use su - and give the root password and then I am root on that distant computer. I can do almost everything you can do on your own computer. That is how I keep the computer on top of the mountain happy. And I can sftp new software and reboot the computer. Not bad.
