WireGuard Manager 👋

🤷 What is VPN ?

A Virtual Private Network (VPN) allows users to send and receive data through shared or public networks as if their computing devices were directly connected to the private network. Thus, applications running on an end-system (PC, smartphone, etc.) over a VPN may benefit from individual network features, protection, and management. Encryption is a standard aspect of a VPN connection but not an intrinsic one.

📶 What is WireGuard❓

WireGuard is a straightforward yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general-purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under a massive development, but it already might be regarded as the most secure, most comfortable to use, and the simplest VPN solution in the industry.

⛳ Goals

robust and modern security by default
minimal config and critical management
fast, both low-latency and high-bandwidth
simple internals and small protocol surface area
simple CLI and seamless integration with system networking

🌲 Prerequisite

CentOS, Debian, Ubuntu, Arch, Fedora, Redhat, Raspbian
Linux Kernel 3.1 or newer
You will need superuser access or a user account with sudo privilege.

📲 Installation

Lets first use curl and save the file in /etc/wireguard/

curl https://raw.githubusercontent.com/complexorganizations/wireguard-manager/master/wireguard-server.sh --create-dirs -o /etc/wireguard/wireguard-server.sh

Then let's make the script user executable (Optional)

chmod +x /etc/wireguard/wireguard-server.sh

It's finally time to execute the script

bash /etc/wireguard/wireguard-server.sh

In your /etc/wireguard/clients directory, you will have .conf files. These are the client configuration files. Download them from your WireGuard Interface and connect using your favorite WireGuard Peer.

💣 After Installation

Show WireGuard Interface
Start WireGuard Interface
Stop WireGuard Interface
Restart WireGuard Interface
Add WireGuard Peer
Remove WireGuard Peer
Uninstall WireGuard Interface
Update this script
