slightly off topic: remotely displaying Mac OS X applications

slightly off topic: remotely displaying Mac OS X applications

[Jonathan Kallay]

My downstairs neighbor has a computer running Mac OS X, which as we all know
has a UNIX backend.  For kicks, I started an X server, telnetted into his
machine, changed the DISPLAY variable to my display, and tried launching a
GUI application.  The application did in fact launch, but on his screen, not
in my X server.  Any ideas as to why this happened?

How did you change the DISPLAY variable?  Did you forget to export it?
Probably your X server will not allow apps on another machine to use
your display (that is generally how X servers are set up).

It is much easier to run remote X applications using ssh, which will
handle them automagically, but if you can't use ssh, there is a
Remote-X-Apps-mini-HOWTO that covers the details of X security.

If you have the howtos installed, it is probably on your machine, or you
can look here:


Remote X Apps mini-HOWTO: Introduction (p2 of 2)

   The most recent version of this document is always available on WWW at
   http://www.xs4all.nl/~zweije/xauth.html. It is also available as the
   Linux Remote X Apps mini-HOWTO at
   http://sunsite.unc.edu/LDP/HOWTO/mini/Remote-X-Apps. Linux
   (mini-)HOWTOs are available by http or ftp from sunsite.unc.edu.

what was sunsite.unc.edu is now calling itself
www.ibiblio.org (and ftp.ibiblio.org, BTW

How _do_ you "change the DISPLAY variable?"

Searching through my wise Debian book I cannot even find it mentioned
at all.

Depends on your shell.

bash:
export DISPLAY=machine.you.want_to_display.on:0.0
tcsh:
setenv DISPLAY machine.you.want_to_display.on:0.0

If you use some other shell, see the man page for it, or at least tell
us what it is.

 I changed the display variable with the command "setenv DISPLAY
 xxx.xxx.xxx.xxx:0.0" (OS X's tcsh doesn't use set/export commands).  I
added
 the host to the list of allowed hosts by running xhost.  I've successfully
 launched remote applications on another computer that have appeared on my
 screen, so the steps should be the right ones...
