I'm trying to run motif on a VMS workstation. That is I want to run mwm off a Ultrix machine, so that it controls the windows on a VMS system. Both the VMS system and the ULTRIX system have decnet. To run the system we have tried: 1) change protection on the VMS system to *::* under the session manager. 2) set host to the ULTRIX machine. 3) setenv DISPLAY to <nodename>::0.0 4) /usr/bin/X11/mwm This results in the "X Toolkit Error: Can't Open display" message. Can anyone help solve this problem? Thanks in advance. Bruce.

You must tell the server that the host that the client is running on is allowed to access the display. On Unix (Ultrix) systems the name of the command to do this is "xhost +<nodename>". On VMS, who knows? regards, fletcher Fletcher E. Kittredge fkittred@bbn.com

You might want to try setting the protrection on the VMS system to machine_name::ultrix-uid-number For example, my machine is "croton", and my uid is "frank" (which is 268 on croton). I would use croton::268 This has worked for me in the past. Regards, Frank

I don't know if this is a typo in the posting or really the problem,
but
> 3) setenv DISPLAY to <nodename>::0.0
has one too may colons in it.

According to Scheifler et al's DP book (p. 11), UNIX clients should specify DECnet connections by using 2 colons. I suspect that the original poster's problem has to do with setting the list of allowed hosts on the machine running the server. Is that server initialized when you try to connect to it?

We set the security on the running session, AND have been able to control the screen with twm under the same scenario. Any more ideas? Thanks, Bruce.
