2908.0. "remote display to idle screen ?" by WELWEL::GRAHAM (Hopelessly Hopeful ! ) Mon Jun 11 1990 09:14

    I have just visited a customer who is writing a Stock Dealing system on
    VAXstation 3100's, VMS and DEcwindows.  He is genraelly pleased but has
    a couple of queries :-
    
    1.	Is it possible to replace the mouse with a tracker ball, if so
    where can one buy it ?
    
    2.	They would like to remove the keyboard from the system and remove
    the need for users to log in via it.  He has two scenarios;
    
    	remove the keyboard and provide a "soft keyboard" on the screen for
    users to log in with.
    
    	remove he keyboard and hav his "server" system grab the VAXstation
    screen without the user logging in.
    
    	Is it possible to remotely display on to the VAXstation without
    someone being logged in ?  I've searched through here and am looking to
    see if DW_net will do the job when it's an Asset.
    
    
    Sorry for the incoherence, it's early Monday morning !
    
    	Regards,

    >Is it possible to remotely display on to the VAXstation without

    Yes (though not documented or supported).  You can create a file called
    SYS$MANAGER:DECW$SERVER_ACCESS_ALLOWED.DAT with the following line in
    it:
    
    	DECNET servernode serveruser
    
    Where servernode is the DECnet node name of your stock dealing system,
    and serveruser is the USER NAME under which the stock dealing system
    runs.
    
    When you start DECwindows, you'll want to only start the server, and
    not the login prompter.

    Re .0 (1.), yes it is possible to replace the mouse with a track ball.
    I've replaced mine with one made by ITAC Systems, Inc., Garland, Texas
    75042. I think i paid around $180 (+- a few bucks, including shipping)
    for it. It's not the greatest ergonomically designed track ball but it
    is plug compatible with the DEC mouse.

RE: Trackball

There's also a company in California (LA area I think) called Evergreen
Systems that makes a DEC compatible trackball.  (compatible with the 
corporate mouse, not the old square box mouse)

2908.490% there, thanks !WELWEL::GRAHAMHopelessly Hopeful ! Tue Jun 26 1990 09:1533
    Thanks for the replies.  I have tested the remote display part and am
    90% there !  What I have done is :
    
    	1.	Created DECW$SERVER_ACCESS_ALLOWED.DAT;2
    
    		DECNET  wellin  manager_dg
    		DECNET  welwel  manager_dg
    		DECNET  welwel  system
                
    	where WELLIN is the boot node and WELWEL is a satellite
    
    	2.	Commented out the line $ RUN sys$system:decw$startlogin
    		in sys$manager:decw$startapps.com
    
    	This presents a blank screen on WELWEL.  From WELLIN I can do
    a set display and run applications (clock, bookreader etc) and they
    will appear on the screen of welwel. 
    
    	The only problem I have is that if I log onto welwel (via set host)
    and try to fire up an application I get an access error -
    
WELWEL$ mcr decw$clock
Xlib:  connection to "WELWEL::0.0" refused by server
Xlib:  Client is not authorized to access server
X Toolkit Error: Can't Open display
%DWT-F-DWTABORT, xtoolkit fatal error
                  
    Why is this ?  Once this is solved then at system startup time a batch
    job can be used to start any local applications.
                                 
    
    Regards,

2908.5Need to authorize LOCAL as well as DECnetSTAR::VATNEPeter Vatne, VMS DevelopmentTue Jun 26 1990 15:157
When you run an application on the workstation itself, Xlib communicates
through a local, shared-memory based transport instead of DECnet.  To
use this, you must also authorize connections using "LOCAL":

	LOCAL welwel manager_dg
	LOCAL welwel system
