I still don't see how this issue matters since this is the nxserver
startup strace - it dies after the server starts up but no trace of
attempt to login occurs

yes but I think by default, PubkeyAuthentication is on as I have been
doing it with another machine since the day I set up the server. For S &
G's though, I did remove the comment and restarted sshd service...

# grep Pubkey /etc/ssh/sshd_config
PubkeyAuthentication yes

I don't think I am getting anywhere on this but thought I would fill in
the replies just in case.

Thanks
