I have never used SSH before. The majority of text here was copied & pasted from "MSG from Xina.md" and then community fixed by XinaA15 users such as "The Bot Guy" (roeegh#3643).
Configure the SSH to be connected to the port: 22
(this should be 22 by default)
If asked for a SSH password, input the default password: alpine
After that, input: ssh root@(your local device IP)
Input the following command and press enter: ssh-copy-id -i $HOME/.ssh/id_ rsa
After that, input: ssh root@(your local device IP)
