Congratulations, you’ve made it this far! You have a server powered by open-source software that you can access from anywhere in the world, safely and securely. Now that you have a solid foundation in Linux and networking, you can start playing with different applications and services. Our final post will look at some tips for making the most out of your new server.
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.
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.
