OPENSSH V8.9-1G bug - no access from detached processes

[malmberg]

I setup a new Community Edition VMS 9.2-2 system for use from Jenkins for Continuous Integration (CI) automation.

The OPENSSH V8.9-1G program is broken in that it will not run commands issued from processes with out a terminal device connected.

A search of the internet reveals other instances of this, so I am not the only one that has seen it.

This is a serious limitation as it prevents many popular cloud management tools from being able to manage VMS systems.

This does not show up in on the VMS 8.4 systems with "VSI AXPVMS TCPIP V5.7-13ECO5F" or on earlier OpenVMS releases.

Code: Select all

I was able to get Jenkins using using RSH as what I used to do for CI controlling VAX/VMS instead of SSH.

Interesting - it works for me in VMS9.2-3 with VSI X86VMS OPENSSH V8.9-1J

You may want to try updating to the latest OpenSSH kit in case it fixes the problem. The kit is available here: https://vmssoftware.com/products/openssh/
