There's not one. Those are the correct commands. From 192.168.20.1 to
192.168.20.3. I left the xkeyboard and font errors in for completeness.

Same error.

(decwclock shows). You may have to consider your install/software kit is
faulty if you are otherwise able to make TCP connections to/from the node.

No firewall, all ports opened in both directions.

Host that runs simh (Rpi 3B running Linux Devuan) is able to open X
applications on Xephyr.

My version of simh was built from source (https://github.com/simh).

I suppose there are some differences between DECWINDOWS V5.4
transport and DW V7.3-010215. If I remeber, I have installed X from
official OpenVMS 7.3 CD... Where can I find DW V7.3-010215 ?
