Hi, Please for help on two [related] problems (I'm probably missing something glaring!):

1)  On my newly installed SL54 on a machine *not* connected to the internet, I tried to connect to a remote machine (Redhat 9) via ssh and it does not allow me. I am lost, as sshd is activated on both machines, and I had used a laptop to make the connection to the remote machine  before. I can ssh connect from the Redhat 9 machine.

QUESTION:  What could I be doing wrong? (script of my attempts below). I can;t pick up what to do from man pages.


2) I tried to open emacs as root, but was not allowed.  I was only allowed connection after I executed 
$ xhost + 
to allow everybody access.

QUESTION: Is there no more secure way of enabling users on local machine to use X without having to enumerate them, or allow all to access? In the past, I've always been able to open a terminal window as root or 3rd party and use without probs.

Regards,

William.
