I thought some may be interested in my ‘Terminal & SSH’ setup on HAOS.
By using GNU Screen, the previous session is recovered so that you can disconnect and reconnect without “losing” your history/view.
I also add a status line and some other configurations to increase efficiency.
You would need to learn screen “a bit”, but the principal key sequence to learn is CTRL-A d which disconnects from the session without closing it.
You can find my setup in a Gist on github .
Home Assistant “Terminal & SSH” screen configuration.
Purpose
- Start gnu screen automatically
when connecting interactively to Home Assistant (keep terminal session
across connections). - Provide a status line in the terminal
- Define some aliases
- Automatically “re-install” after add-on upgrade (create symbolic links,
.vimrc, .viminfo) - Use vim when calling vi
How to
- These files reside in /data
- The “Terminal & SSH” add-on automatically relinks the .bash_profile
script (see /etc/cont-init.d/profile.sh ) - Add the appropriate apks to your “Terminal & SSH configuration”. This is
what my configuration looks like. You only need the ‘screen’ apk, I
suggest the other ones (database access, install python modules):
authorized_keys:
- >-
ssh-rsa
PRIVATE_KEY PRIVATE_ALIAS
password: ''
apks:
- screen
- etckeeper
- sqlite
- py3-pip
server:
tcp_forwarding: false
For an unknown reason, screen is broken on HAOS since quite a while - for some reason it tests all potential descriptors to find terminals which takes a very long time.
So I disabled it for the time being. I filed a bug report to GNU Screen, but I’ld need to follow up on it.
Maybe I’ll switch to tmux - which is already possible for anyone else ;-).
