I have been trying to connect to HA via SSH port 22222 for the last month to look at config.txt (Yes it’s taken me that long )
I’ve installed OpenSSH and I can connect to HA port 22222 (or any other port) using a Password only, as soon as I put in a authorized_key I get connection refused.
I my question is, is my ssh key formatted correctly? (I have tried googling this)
Mine are all of the second form, starting with - ssh-rsa ..... You can also get to some system-level resources, such as docker, by using the community “SSH & Web Terminal” add-on and turning off Protection Mode, but I don’t know if that’ll let you get to config.txt (in /boot on your machine?).
I have managed to get a correct key and it will allow me to log in, the only issue now is that there is no boot dir within the mnt folder even though I am logged in via port 22222.
