Prerequisites Before You Start

Before we begin, let's get a few things in order, alright? First off, you'll need a server running OSCOSC. It could be a virtual private server (VPS) from a provider, or if you're feeling adventurous, a server at your home. Make sure you have root or sudo access to this server, because we're going to be doing some serious system-level configuration. Ensure you have a stable internet connection for your server, as a flaky connection will make the whole process a headache.

Next, you'll need a basic understanding of the command line. Don't worry, you don't need to be a Linux guru, but knowing how to navigate directories and run commands is essential. We'll provide the exact commands, so you can copy and paste, but understanding the basics will help you troubleshoot any issues. Make sure your server's firewall is set up and configured. We'll need to open specific ports for OpenVPN to function correctly. The most common port is UDP 1194, but you can choose a different one if you wish. We'll also need to consider any security implications of opening these ports and configure the firewall accordingly. If you're using a VPS, your provider likely has a firewall configured, so double-check those settings as well. To make your life easier, it's helpful to have a text editor installed on your server. This will allow you to modify configuration files easily. Nano or vi are common choices, but use whatever you're comfortable with. If you plan to connect to your VPN from various devices, make sure you have those devices ready. You'll need to install an OpenVPN client on each one, and we'll walk you through the configuration process. We will create and manage certificates for the server and client connections. This ensures that only authorized devices can connect to your OpenVPN server. We'll also cover best practices for securing your OpenVPN server, including regular updates, strong passwords, and monitoring your server's activity. By taking these preliminary steps, you'll be well-prepared to follow this tutorial. Ready to dive into the exciting world of OpenVPN? Let's get started.

Installing OpenVPN and Easy-RSA

Alright, let's get down to business and install OpenVPN and Easy-RSA. These are the two main tools we'll need for our setup. First, let's update your server's package repository to make sure we're getting the latest versions of everything. Run the following command in your terminal:

sudo apt update

After updating the repositories, install OpenVPN and Easy-RSA using the following command:

sudo apt install openvpn easy-rsa -y

This command installs OpenVPN and Easy-RSA on your server. Easy-RSA is used to manage SSL/TLS certificates, which are essential for securing the connection between your clients and the server. After the installation is complete, navigate to the Easy-RSA directory. Usually, it's located in /usr/share/easy-rsa/. Use the cd command to enter this directory:

cd /usr/share/easy-rsa/

Now, let's initialize the Easy-RSA environment and generate the Certificate Authority (CA) certificates. You'll use the following commands:

sudo ./easyrsa init pki
sudo ./easyrsa build-ca

The first command initializes the PKI (Public Key Infrastructure) directory. The second command generates the CA certificate. You'll be prompted to enter some information, such as your country, state, and organization name. Fill these out as you see fit. For the Common Name, you can use your server's hostname or a descriptive name like
