How to Install OpenVPN on Kali Linux

OpenVPN is an open-source VPN system that enables you to create a secure network connection over the internet. In this tutorial, we will show you how to install OpenVPN on Kali Linux, the latest edition.

Prerequisites

To start this tutorial, you need:

  • A Kali Linux machine
  • Root access

Step 1: Install Required Dependencies

First, we need to install all necessary dependencies to build and set up OpenVPN. To do that, execute the following commands as a root user:

$ apt-get update && apt-get install -y openvpn openssl wget unzip

This command will install OpenSSL, wget, unzip, and OpenVPN on Kali Linux.

Step 2: Download OpenVPN Configuration Files

Next, download OpenVPN configuration files from the official website. Go to the OpenVPN website and download the .zip file for the desired region/server.

$ wget https://downloads.nordcdn.com/configs/archives/servers/ovpn.zip

After downloading, unzip the file in the server directory.

$ unzip ovpn.zip -d /etc/openvpn/

Step 3: Configure OpenVPN Settings

Now we need to configure OpenVPN settings by editing the file:

$ nano /etc/openvpn/nordvpn.ovpn

Replace the contents of the file with the following configuration:

dev tun
proto udp
remote x.x.x.x 1194
resolv-retry infinite
nobind
persist-key
persist-tun
cipher AES-256-CBC
auth SHA512
tls-client
remote-cert-tls server
auth-user-pass /etc/openvpn/credentials
comp-lzo
verb 3

Replace the "remote x.x.x.x" with the server IP address you want to connect to.

Step 4: Create OpenVPN Login Credentials

To connect to OpenVPN, we need a username and password for authentication. Create a file called credentials in the /etc/openvpn/ directory, and add your login credentials in this format:

your_username
your_password

Step 5: Start OpenVPN Connection

Finally, we can start the OpenVPN connection using the following command:

$ openvpn --config /etc/openvpn/nordvpn.ovpn

The process will run in the terminal window to connect to the OpenVPN server.

And congratulations; you have successfully installed OpenVPN on Kali Linux and can use it to connect to a secure network connection.
