Reasons for not being able to open a remote shell

[MSCHMEL]

Hello everyone,

can you tell me under which circumstances it is not possible to connect to a running container using rsh? I recently had that problem. Unfortunately, I cannot remember the exact error message. Can a container be configured in a way to just refuse rsh connections?

Thanks and kind regards,

Matthias

Hard to tell without looking at the error and configuration. But there could be a bug with the image as well eg docker exec or oc rsh does not work with registry.access.redhat.com/rhel7:7.3  but it works with registry.access.redhat.com/rhel7:7.4 onwards.

Or if there is a pod disruption budget error and you cant evict unhealthy pods, so doing rsh to one of the pods will fail.

Or may be the command was wrong.

Thank you. Next time I have that problem I will make sure to take note of the error message.
