	They are valid for the life of the X server.  When you log out,
the X server shuts down, and gdm/xdm generates a new cookie.

	I would use a script to pull the cookie out using xauth nlist,
or something similar, and ssh over to the Solaris box and xauth the
cookie in and launch your program.

	If you do so, make sure the ssh thingy launches the program on
display 0.  ssh sets up an X tunnel by default, and sets the DISPLAY on
the remote machine to the tunnel address.

	Of course, you could use rsh if you're on a secure network.  I
had a perl script once that handled sending the xauth information
automagically.

	You could just use the X forwarding ability of ssh, but then
you're adding in lots of extra overhead that isn't really necessary.

Have fun (if at all possible),
