Hi Massimo and all,

I finally got X over ssh to work. (The trick was to add an ORIG_DISPLAY.)
I added what I did to my lts_ssh package available at

http://www.geocities.com/patpertusus/

It didn't slowed much my workstation, however my setup is only one workstation,
so maybe it slows down the server.

Basically it works the following way:

The user authenticate on the tty against the ssh server and at the same
time download his private key. ssh-agent/ssh-add adds the private key, and then 

xinit /usr/bin/ssh -X server 'ORIG_DISPLAY=workstation:0 start-window-manager' -- 
Xserver

begins the X session.

The advantage of this setup is that there is no secret to be shared with the
server, and at the same time all the X stuff, the password, and so on is
encrypted.

It doesn't protect against man in the middle attack, but I think nothing can
protect an Xterminal from such an attack.

Maybe it would be even better if everything was graphical, and if it was
possible to choose a server among other, or if the server could advertise how
loaded he is, or if it was possible to choose vnc or X at the login.

Pat
