[CLUE-Tech] Xauth problems

[Ronald Brink]

Have you tried in addition to setting your DISPLAY variable on the linux box
pointing to your nt IP, also running "xhost {ip}" or "xhost +" (as root on
the console) to allow client connections?  That may fix your problem.
Normally I don't "take over the console" I just run whatever X progam; i.e.
xterm.

Sorry Rick, you lost me.  Seems to me you want xterm to run on Redhat and
display on NT,
right?  When I used to do that with Omni-X, there was no Xauth involved.

Omni-X had a dialog that you could put a command line in (we used rexec to
execute it, but
I think there were rsh and telnet methods too).  You put the xterm command
line in the
dialog, including all the options like display IP (omni-x can fill that out
automatically).

When you run that command line from omni-x, it asks you for a password (for
rexec) and
runs the command on the server.  So xterm gets run as you, and displays on
NT (I don't
think omni-x does any security - or is that the problem you're having?)

So I don't understand where your script (below) is used.  I don't think
you're running the
xterm on NT and displaying on Redhat, are you?  (How do you run an xterm on
NT?  I guess
it could be done, but I never seen it.)

Sorry I don't have omni-x handy to be more specific.  One final guess, in
your script
below, should $display be $DISPLAY?
