Hello Darren,

There were problems with the permission in accessing the home folder
(/root).  With other users I am able to connect with the RSA key.

Thanks for the inputs.

The log that is likely to have useful information is on the server.  Try

  running sshd in debug mode (eg "/path/to/sshd -ddd -p 222" and point 
your client at port 222).

The usual cause of pubkey not being accepted is the permissions of the 
.ssh/ directory (which you mention you have checked) and the permissions

of the user's home directory (which you didn't mention).

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
