Knowledgebase

WireGuard is a modern VPN (Virtual Private Network) software that offers state-of-the-art encryption and performance. It's a simple yet powerful tool for creating secure point-to-point connections. This guide provides step-by-step instructions on setting up WireGuard on a Linux VPS (KVM) running Debian or Ubuntu at ArkHost. Please note that WireGuard requires kernel support, which is available in our Linux VPS (KVM) products but may not be compatible with other types of virtualization like Containers (KVM).

1. Understanding the Requirements

WireGuard operates as a kernel module, interacting directly with the Linux kernel. This means it offers better performance and reliability but requires a compatible environment:

• Linux VPS (KVM): This guide is specifically for Linux VPS (KVM) users at ArkHost. WireGuard's kernel module aspect means it works best on systems that offer full kernel control like KVM virtualized environments.
• Debian or Ubuntu: The instructions below are tailored for Debian or Ubuntu operating systems. Ensure your VPS is running one of these before proceeding.

2. Installing WireGuard

Installation of WireGuard on Debian or Ubuntu is straightforward. You'll be using a script that automates the installation and initial configuration process:

1. Download the WireGuard installation script: curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
2. Make the script executable: chmod +x wireguard-install.sh
3. Run the installation script: ./wireguard-install.sh

Follow the on-screen instructions to complete the setup. The script will guide you through the configuration of your VPN, including setting up server and client details.

3. After Installation

Once WireGuard is installed and configured, you can start using it immediately. Here are some tips to ensure smooth operation:

• Managing WireGuard: Learn the basic commands to start, stop, and manage your WireGuard interface. Typically, these involve wg-quick up and wg-quick down commands.
• Security Best Practices: Regularly update your system and WireGuard to the latest version to ensure you have all the security enhancements and bug fixes.

Important Notes:

• Kernel Module Requirement: WireGuard requires a Linux kernel version that supports WireGuard. Most modern Linux distributions will meet this requirement, but always verify before installation.
• Compatibility: This setup is intended for Linux VPS (KVM) at ArkHost. If you are using another type of service, such as Container VPS (KVM), consult the relevant documentation or support services for compatibility and setup instructions.

By following this guide, you'll have a secure, high-performance VPN setup using WireGuard on your Linux VPS (KVM) at ArkHost. As with any system changes, ensure you understand each step and its implications for your VPS and its security. If you encounter any issues or have questions, ArkHost support is here to help you through the process.
