Private Server Part 6: Public Access, Advanced Networking, and Advanced Security


If you’ve been following the previous steps of this guide, you should have a secure, freshly updated installation of Ubuntu Server which you can access from another computer on the network using SSH. If that’s the case, you can safely unplug the keyboard and monitor from your server – you won’t be needing them. If you’re running your server behind a router (e.g., on a home network), chances are your server won’t be accessible from the outside world. This section explains how to make your server available to the public Internet so you can access it from home or while on the go.

Private Server Part 5: Web Hosting, ownCloud, and Subsonic

At this point, you should be able to access your server through your local network. You won’t be able to access it from the Internet, but don’t worry about that just yet. There are a couple of important security steps before your server goes public that we’ll get to later. In the meantime, let’s focus on the real reason you’re here: hosting your own file sync and music streaming services locally.

Private Server Part 2: Installing the Operating System

You have a big box full of complicated-looking electronics, a monitor, a keyboard, and cords going all over the place. Now what? If hardware can be considered the body of the computer, then the operating system can be considered its soul. The operating system acts as an interpreter between you and the hardware, translating your actions into instructions that the machinery can understand. It does everything from reading the keys you type to displaying text on the screen. More importantly, it’s what turns a pile of metal and silicone into what we consider a modern computer.

Why I Run My Own Server

Home server

As a way to keep myself up-to-date with trends in networking and web design (and as a way to keep myself occupied on really boring days), I run a private server. Many of the services we take for granted – email, online calendars, address books, chat programs, and media streaming to name a few – are provided by companies in exchange for access to the information used within them. In networking terms, this is called the client-server model: the client (your web browser, smartphone, etc.) makes a request to a server, which is run by a service provider such as Google, Apple, or Microsoft.

Meditation in Motion

The word “meditation” often invokes images of a man sitting cross-legged, arms folded in his lap, smiling peacefully. It encourages reflection, introspection and personal exploration. While this is all perfectly acceptable, there’s a form of meditation that not a lot of people choose to explore or even understand as being a form of meditative practice. The ironic thing is, it’s something that all of us are doing at every waking moment of every single day.

An Introduction to Free Software

While the term “free software” seems self-explanatory, there’s a lot of confusion surrounding the actual definition and usage of “free.” Before we define it, it’s important to know that free software is usually used interchangeably with open source software. Free software is exactly what it says on the tin; you can download it and run it without having to pay the owner a dime. Although the software is free to use, it may contain restrictions that make it difficult to modify, distribute, or resell. Open source software eliminates these restrictions by not only allowing the user the download the software, but also to study and change the source code and redistribute the modified program. The Latin words “gratis” and “libre” are often used in place of “free” and “open source” to prevent ambiguity.
