A Raspberry Pi File and Print Server

I was recently looking into the options to buy a living room “home server” to centralize certain services like file and print server, media server, etc.

This was of course the pretext to buy my first Raspberry Pi. A few more should follow… This article starts a little series explaining what I did and how I did it. Today, I will look at the first and simplest type of server: Continue reading →
