How to Install OpenVPN on Ubuntu

OpenVPN, a robust and widely used Virtual Private Network (VPN) solution, provides a secure and reliable way to browse the internet, access remote resources, and protect sensitive data. As a popular Linux distribution, Ubuntu offers a fertile ground for OpenVPN installation, allowing users to leverage the power of VPN technology on their Ubuntu systems. However, installing OpenVPN on Ubuntu can be a daunting task, especially for those without prior experience with VPNs or Linux.

In this tutorial, we will discuss the process to install OpenVPN on Ubuntu, providing a step-by-step guide to help you get started with securing your online presence. We will cover the prerequisites, installation, configuration, and connection processes, ensuring that you have a fully functional OpenVPN setup on your Ubuntu system. By the end of this tutorial, you will be able to enjoy the benefits of secure and private browsing, protected from cyber threats.

Installing OpenVPN on Ubuntu

Here’s a step-by-step guide to installing OpenVPN on your Ubuntu system:

Step 1: Update Your System

Before installing any new software, it’s crucial to check Ubuntu version, update your system’s package list, and upgrade any existing packages. Open your terminal and execute the following command:

sudo apt update && sudo apt upgrade -y
update and upgrade

This ensures you have the latest software versions and dependencies, preventing potential conflicts during the OpenVPN Ubuntu client installation.

Step 2: Install OpenVPN

With your system updated, you can now install the OpenVPN package. Use the following command in your terminal:

sudo apt install openvpn -y
openvpn install

This command downloads and installs OpenVPN and its necessary components. The -y flag automatically confirms any prompts during the installation process.

When you run the command sudo apt install openvpn -y you might notice additional packages being installed alongside OpenVPN. Let’s break down what these extra packages are and why they’re needed:

  • Additional Package: libpkcs11-helper1: This package provides a helper library for applications that use PKCS#11, a standard for interacting with cryptographic tokens and smart cards. OpenVPN can utilize this library for enhanced security features like hardware-based key storage, although it’s not strictly required for basic functionality.
  • Suggested Packages: resolvconf: This package helps manage your system’s DNS settings. While not mandatory, installing resolvconf can assist OpenVPN in seamlessly switching DNS servers when connecting and disconnecting from the VPN, preventing potential DNS leak issues.
  • openvpn-systemd-resolved: This package integrates OpenVPN with systemd-resolved, a system service for resolving DNS queries. Similar to resolvconf, it contributes to smoother DNS handling while using OpenVPN.
  • easy-rsa: This package provides a set of scripts for generating and managing RSA certificates. While OpenVPN comes with pre-generated certificates for its default configuration, easy-rsa is beneficial if you plan to set up your own VPN server or require more advanced certificate management.

Step 3: Start and Enable OpenVPN Service

After installing OpenVPN and configuring your connection, you need to start the OpenVPN service to establish a VPN connection. Moreover, enabling the service ensures it automatically starts every time your Ubuntu system boots, providing seamless VPN protection:

sudo systemctl start openvpn
sudo systemctl status openvpn
systemctl openvpn

The command sudo systemctl start openvpn instructs your system to initialize and run the OpenVPN service. This command reads your OpenVPN configuration files and attempts to establish a connection to the specified VPN server.

To ensure OpenVPN starts automatically whenever your system boots up, you use the sudo systemctl enable openvpn command. This command configures the OpenVPN service to start at system startup, eliminating the need to manually initiate the connection every time.

Finally, to confirm that OpenVPN is running as expected, use the command sudo systemctl status openvpn. This command provides a detailed report on the OpenVPN service, including whether it’s active (running), any errors encountered, and other relevant information.

If the status shows “active (running),” your OpenVPN installation is successful, and you’ve established a secure VPN connection. You can now enjoy the benefits of enhanced privacy and security while browsing the internet.
