93.0. "VMS->Ultrix connection problems" by VOGON::DRUMGOOLE () Wed Feb 01 1989 12:37

 I have a problem with executing remote applications from a VMS workstation
while using a server running on an Ultrix workstation. The situation is this,

I am logged in on my Personal Workstation ( VAXstation II) running Ultrix.
I set host to a VMS workstation and attempt to execute a remote application
on the VMS workstation. Before running the application I set up the VMS
logical name DECW$DISPLAY to point to the Ultrix machine. The Ultrix m/c
name is 9dart and DECW$DISPLAY is set to "9DART::0". 

However this doesn't work as everytime the application on the VMS m/c is 
started it fails with an Xtoolkit error : can't open display. I have set
the protections within the security dialogue box to give the VMS m/c access
to 9dart's display.

Has anybody else experienced this problem ?

Is there a solution ?

Joe.

    Whose security dialog box is being invoked?

93.2Similar difficulties...WINERY::ROSEWed Feb 01 1989 13:134
    I've experienced a similar problem, see 23.3 in this notesfile.
    However, the error message I get is not "can't open display" but rather
    "xlib i/o error".

The format for enabling security is different on VMS and Ultrix.
Be sure you're using the appropriate format.

You mentioned that you had set DECW$DISPLAY to "9DART::0"
If you're using SET DISPLAY you just say "/node=9DART", if you
want you can add "/screen=0".  On an earlier base level you could
say "set display/node=9dart::0" but this no longer works, and you
don't get a meningful error message.

    Whose security dialog box is being invoked?

    The Ultrix m/c's dialog box is invoked before logging into the VMS
 m/c.

    re:.4
    
    Ok, then a few questions and points:
    
    1.  Does the ultrix server have the correct host address for the vms
    client?
    
    2.  When VMS is involved or _linger isn't used on u*ix sockets, there
    is a race between sensing a link is dropped and getting back data. 
    This is especially interesting when the server disconnects because the
    client wasn't authorized.  Try a few times.
    
    3.  Momentarily disable access control on the server and see if the vms
    system connects.

This is like the instructions on a TV to make sure it is plugged in, but...

Are you sure the Ultrix machine is running DECnet?

-------------------
FYI, while Andy's discussion of SET DISPLAY/HOST is correct, that is not your
problem.  The way you did it should still work.

Do double check to make sure that your Ultrix machine understands the name
of your VMS machine as Monty said.  Try, for example, 

	dlogin <vmsmachinename>

If that does not work, you need to find out where your network problems are.

 -> Yes.

 -> Set display/host fails out of hand, unrecognised qualifier.

Do double check to make sure that your Ultrix machine understands the name
of your VMS machine as Monty said.  Try, for example, 

	dlogin <vmsmachinename>

 -> I have to dlogin to execute the application so thats not the problem.

copy NETRIX::~thomas/tmp/dstat to your 3.0 systems and either
post or mail me the results of

dstat -f dnet -a

BTW, that should be SET DISP/NODE=

    re .-1 and .-2:  RIght.  SET DISPLAY/HOST is not real.  It was the
    fingers working faster than the brain.

    I have the same problem. set display/node=GILISH gives me 
    %SYSTEM-W-NOSUCHDEV, no such device available
    
    Interestingly I rebooted the same machine under VMS and got the
    same error. I dlogin to the server (or SET HOST depending on o/s),
    so I'm connected. I can set host back again from the server.
    
    I tried SET DISPLAY/CREATE/NODE=GILISH
    
    No difference.
