SSH Printer Password Config File

[SOliver78]

Hi, would it be possible to create or add a config file for SSH access to the K2 Plus etc.?

I changed the root password and manually added it to the following line in main.py:
_SSH_PASSWORDS = ["xxxxx", "creality_2023", "creality_2024", "creality"]

Of course, this gets overwritten during an update.

But thanks a lot for the excellent work.

I’ve written a Bash script that modifies main.py so that it first reads data/ssh.json and then the default passwords from main.py. I’m posting the script here because I’m unfortunately struggling to figure out the pull request process ;)
Perhaps someone else could submit a pull request based on this?
