I am unfamiliar with Ubuntu and Linux in general. I bought 3 old Dell PowerEdge 2650 servers off eBay for £20. I didn't really know what I was going to do with them, but for the price, they seemed unbeatable. I would like to learn to get used to using Linux as it seems the web virtually runs off Linux!
I thought Ubuntu would be a good place to start, and so I put a slightly outdated version of Ubuntu on the servers, because some of the newer versions would not install for some reason.
Anyway, now I am thinking that I would like to run one of the servers as a VPN. However, I installed the desktop version of Ubuntu as I thought a GUI would be a better place to start off for me. Is this a problem? I thought this would be a great idea as it would get me started in the world of networking and security.
I would like to eventually have all the internet traffic from the rest of my computers routed through the server safely. I assume this means using the PPTP protocol, which I have only briefly heard of.
If you have any advise for me, resources to begin learning about Ubuntu, or how to get started with this stuff then please reply.
