Hi I am not new to Ubuntu but totally new to Ubuntu server and have spent the last couple of days getting more and more confused. If my question has been asked a million times please accept my apologies, I can't find it but a link to it would greatly appreciated.
I have an old PC (fairly good specs) that I have decided to turn into a media server using Ubuntu 12.04 lts server iso. The only requirment I need my Ubuntu server to do is to perform as a cloud for all of my personal media that can only be connected internally within range of my home WiFi. Further, I don't want to be able to use any Web apps to connect. I just want a PC that will serve my media to my laptop phone xbox 360 etc.
I would also like to do this in the most secure way possible. Is this something i can achieve? Can anyone walk me through it please?
