I often spin up a quick python http server. Just go to the folder which has the files you want to transfer and run the following command: python3 -m http.server. This will server the folder content Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) .... On your phone you can then browse to http://PC_IP:8000 and download what you want/need.

You could add encryption and authentication via ssh: https://guide.munin-monitoring.org/en/latest/example/transport/ssh.html or you could put it behind an nginx and wrap it in tls if you just want encryption.

Munin might be what you’re looking for. Very simple and easy to write your own plugins for if some information is missing.

Good for you! I’ve been free of windows for a decade I think. There’s nothing I miss as most of the programs I like and need have linux versions. The main program holding me back was reaper, an audio editor, and when they released an alpha version for linux I erased my last windows hard drive. I only run debian stable, but I’m not too fussed with bells and whistles.

I used the bandit game as an in class exercise when I was teaching basic linux skills to aspiring system administrators. It was always a great success because everyone got to advance at their own pace. Plus, they felt like real hackers because it was really over ssh. Anyway, have fun!
