I don't use SSH or XDM, but nonetheless was intrigued by your question about
running XDM via an SSH tunnel. After some poking around, it occurred to me
that there might be a way to make this work by finding and editting the
Xservers file on the XDM server. The process would go something like...
1) Launch XWin without the -query business.
2) Set DISPLAY=127.0.0.1:0 then run "ssh -x <xdmserver>" to bring up a
tunnel into the XDM server.
3) Once connected, edit the XDM server's Xservers file and create a "local"
entry for the display number handled by ssh.
4) Send a SIGHUP signal to XDM to tell it to re-read the Xservers file and
start managing the virtual DISPLAY setup by ssh.
The one thing I'm not sure abouit is what would happen to XDM after the SSH
tunnel ended. Will it continuously loop trying to start an X session on the
defunct DISPLAY?

It will try a few (5 afair) times and then disable the entry for 30 minutes.

I am trying to connect to a SGI Onyx 300 server from an PC with Win ME and
cygwin at home through typical
Xwin.exe -ac -query remote_ws -from <my local computer IP name >
but the remote login screen doesn't appear properly. It's just a blank
window.
I think my problem is really with local IP setting. I am not sure about my
local IP.
It is a 3 pcs LAN connectting to the internet through a router. My pc got a
local IP: 192.168.0.3, whist 3pcs share one external IP(as gateway) provided
by ISP.
But neither of the IPs can work(openning DISPLAY).
My problem is only with an XDMCP-query session.
What I must do to access a machine with SSH and "X -query" in this case?
Thanks in advance.
Philip D.
