P2P server connection using Raspberry Pi
Here's the thing: You have a Rpi(Short for Raspberry) in your room. Your friend Jack lives in another city. You two work on projects and need to share files. Your friend bought a Rpi for something but its useless now. You plan to connect two of these Rpis so that you can send or receive files(Security aside). How do you connect them? I know not much about networking but If you do you can answer it. Just summery or blog post link would be fine.
