Cannot display applications from a VAX/VMS 7.3 server on the local PC

Dear experts,
I'm a OpenVMS hobbyist and I have a MicroVAX 3100-90 running OpenVMS VAX 7.3.
Now I'd like to open some applications such as clock.exe or terminal.exe on the MicroVAX and let them display on my local PC running Ubuntu Linux.

I've already tried following so far:

$ SET DISPLAY/CREATE/TRANSPORT=TCPIP/NODE=192.168.3.10
$ sh disp

Device: WSA1: [super]
Node: 192.168.3.10
Transport: TCPIP
Server: 0
Screen: 0

$ run decw$clock.exe
X Toolkit Error: Can't Open display
%DWT-F-NOMSG, Message number 03AB8204
$

Hope you can help me to solve this issue.

Please feel free to ask me for further details, if needed.

Kind regards

Can you run for example xclock ( xeyes ) on the desktop?
( /usr/X11R6/bin/xclock ?)

Do you have the xserver running on the desktop?
Maybe: /usr/bin/X11/X -multiwindow ... &

Did you authorize incoming requests from the VMS system?
Maybe: xauth / xhost +

fwiw

If this is just a hobbyist thing, and your local network is 'trusted'.

Check that your Linux box accepts TCP connections (often it will be started -nolisten tcp).

Make sure port 6000 isn't firewalled.

Mr. van den Heuvel, thank you for your input. Unfortunately everything you've mentioned was already set up correctly (I think).

Mr. Brodie, you were right! The "-nolisten tcp" option of the X server was active. After starting X without "-nolisten tcp" everything works like a charm.
Thank you very very much!

Can you try a

$ mc decw$examples:ico

Ico.exe usually gives better error messages.
