Sometimes a question is just so common, and so much has been posted about it, that you can’t actually find the answer anymore and have to start fresh
I run HA and HAOS on an RPi4 located in a closet. My understanding - and I hope this is right - is that HA is not in a container. I want to get full remote access to an HAOS command shell, via Telnet. It looks like telnet isn’t enabled - without attaching a keyboard and display to the Pi, is there a way I can turn it on? It seems I can’t get a real command shell from within HA, over the web.
( I want Telnet, not SSH - I know many will disagree but I need access from several systems and I’m not messing with all those keys.)
Also, to avoid the inevitable coming confusion, you have to follow the procedure below to get access to HAOS itself in SSH. The “Terminal & SSH” addon is just another container.
Having shell access to a system, especially HAOS, is not a goal. It’s a mean to reach a goal.
The only reason why I use shell access to HAOS is to get full addon logs, which I didn’t find another way to obtain. You cannot/are not supposed to do anything through the shell, beyond debugging.
