I'm trying to get more familiar with *nix.

Today I downloaded and installed Cygwin/X on to my WinXP machine at work. I
could then ssh into my Fedora Core 5 Linux box and run 'konqueror &' and the
Konqueror web browser would be displayed on my WinXP box.

How do I do the same with our Mac OS X 10.4.x box with X11 installed?

I can successfully ssh into it. The DISPLAY environment variable has been
manually set with:

export DISPLAY=ip_address_of_winxp_box:0

/etc/sshd_config has been modified with the line
X11 Forwarding Yes (instead of No)

When I run:

/Applications/Safari.app/Contents/* MacOS/Safari &

it comes back with an error something along the lines of "only root or the
console user can do that", so then I did:

sudo /Applications/Safari.app/Contents/* MacOS/Safari &

Safari comes up but its displaying on the Mac box and not my WinXP box.

What am I doing wrong?

Yes ssh -X or ssh -Y will work., that way you don't have to set the
DISPLAY variable.

As others have already stated, you can only do this with X11 apps, not
Safari nor any other Mac application.

However, you should be aware that what you are doing (according to the
description) is *not* secure X11 forwarding. X11 forwarding implies that
you forward the X11 traffic over your SSH link. When you set DISPLAY to
ip_address_of_winxp_box:0 you tell the X11 traffic to pass over the
internet in the clear instead of over SSH.

As another poster said, to use secure forwarding of X11 you need to use
the SSH options -X och -Y. Then your DISPLAY variable will be correctly
set (most probably to localhost:10.0) and your X11 traffic will be
encrypted.

Thanks for this very handy tip. I shall use ssh -X instead of exporting the
DISPLAY environment variable.

It is not possible to display Safari on your X workstation.
