OpenVMS 7.3 on SIMH VAX - Docker Container with DEC Windows via VNC

https://hub.docker.com/r/tenox7/openvms73

Running

docker run -it --rm tenox7/openvms73:latest

Login as system password is systempassword.

Telnet

To telnet/ftp/rlogin/rsh to the guest add -p, for example for telnet:

docker run -it --rm -p 23:23 tenox7/openvms73:latest

VNC to DEC Windows

Conveniently this container now contains a VNC Server with X11 XDMCP Query. You can just VNC in to the container! The password is vncvms. On MacOS you can simply open vnc://127.0.0.1.

docker run -it --rm -p 5900:5900 tenox7/openvms73:latest

Change resolution: -e GEOMETRY=1920x1200

X11

To forward X11 XDMCP Query add -p 177:177/udp:

docker run -it --rm -p 23:23 -p 177:177/udp tenox7/openvms73:latest

I was not able to connect to it unless the client display is :0. In particular Xnest -ac -query :1 did not work for me. Only :0 does. If you know how to fix it, LMK.

Persistent State

WARNING: by default the guest is ephemeral, the state is NOT preserved once you exit from the container.

In order to persist the data disk mount /data as a volume or bind mount:

docker run -it --rm -v path:/data tenox7/openvms73:latest

The disk image and nvram is stored in /data in the container.

Quiting

Ctrl^E in the terminal will shut down SIMH.
