Tbh I don't really know what any of what you said is but I want to learn. Terminals aren't a problem for me I'm doing everything with command line. Because the box isn't powerful enough to run a graphical interface.
My dad already has a file/media server set up at my house. He's the one who's been helping me along. And I'm going to use it for a VPN because my router is blocking the VPN I tried to set up on my windows machine. So I'm thinking about putting the Linus box outside the DMZ because it's less risky.
I just installed linux on this cheap android tv box. Now I don't know what to do with it. What are some easy things, interesting things, or things that will help me learn more about linux etc.? I am planning on setting up a VPN on it in the future.
