Re: Running multiple servers from Windows Terminal Server

[Harold L Hunt <huntharo at msu dot edu>]

Salah,

There are three components to the DISPLAY variable:
IP_ADDRESS_OR_HOSTNAME:DISPLAY_NUMBER.SCREEN_NUMBER

Your X1.bat sets DISPLAY to 127.0.0.1:1.1, but you never tell XWin.exe that 
it is using display 1.  You tell XWin.exe to use a different display number 
with the ``:n'' parameter:

XWin :1 -screen 1 -query host_foo


Also, it is a really bad idea to use the ``-ac'' parameter on a network with 
other users... this allows any host to connect and snoop on the X display, 
possibly grabbing passwords and/or screenshots, etc.

You do not need to specify the 1024x768x16 information with the ``-screen'' 
parameter and it is probably better that you do not (in which case XWin.exe 
will size its window to fit the available desktop area).

You do not need the ``/B'' parameter on start anymore.  XWin.exe 
automatically detaches from the console now.

Finally, you do not need to, and it is recommended that you do not, specify 
the ``-engine n'' parameter.  The server automatically determines which 
engine to use based upon which version of DirectDraw is installed.  In fact, 
it will ignore your request to use an engine that conflicts with the version 
of DirectDraw installed, so you might as well just leave off the -engine and 
let XWin.exe figure it out for you.

I would have the following:

X0.bat:

set DISPLAY=127.0.0.1:0.0

start XWin -query peis07


X1.bat:

set DISPLAY=127.0.0.1:1.0

start XWin :1 -query peis07


Good luck.

Harold
