Installing OpenVPN on Ubuntu 20.04

OpenVPN is an open-source VPN (Virtual Private Network) application that allows you to securely connect multiple devices over the internet. It provides a secure and encrypted connection to protect your data and activities from unauthorized access. OpenVPN uses SSL/TLS protocols for authentication and encryption, providing a reliable and secure VPN solution.

To install OpenVPN on Ubuntu 20.04, follow the steps below:

1. Update the system packages by running the following commands in the terminal:

   sudo apt update

   sudo apt upgrade

2. Install OpenVPN and the necessary dependencies using the following command:

   sudo apt install openvpn

3. Once the installation is complete, you can configure OpenVPN by creating a configuration file. Open the terminal and navigate to the directory where you want to store the configuration files. Use the following command to create a new .ovpn file:

   sudo nano .ovpn

   Replace `` with the desired name for your configuration file.
4. In the editor, you need to specify the connection settings. Here's an example of a basic configuration:

             
               client
               dev tun
               proto udp
               remote  
               resolv-retry infinite
               nobind
               persist-key
               persist-tun
               key-direction 1
               remote-cert-tls server
               tls-version-min 1.2
               tls-client
               cipher AES-256-CBC
               auth SHA256
               verb 3
             
           

   Replace `` with the IP address or hostname of the OpenVPN server you want to connect to and `` with the corresponding port number.
5. Save the configuration file and exit the editor by pressing Ctrl + X, then Y, and finally Enter.
6. To establish the OpenVPN connection, run the following command in the terminal:

   sudo openvpn --config .ovpn

   Replace `` with the name of your configuration file.
7. Enter your sudo password when prompted, and OpenVPN will initiate the connection. You will see the logs indicating the connection status.
