Hi Malcolm,

I have installed the kerberos services; same message: the remote system
has refused the connection.
service telnet
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/sbin/in.telnetd
disable = no

Meanwhile I tried ssh2: try to connect via ssh2 with a user, the
following message will shown:

The server has disconnected with an error. Server message reads:
A protocol error occurred. Change of username or service not allowed:
(root,ssh-connection) -> (scm.adm,ssh-connection).

All so confusing me...

Strange indeed, sure you don't have a mis-configure hosts file, dns
setting sending you to the wrong machine?

Maybe run ssh and wind up the verbosity when you connect...
ssh -vv user@target
