InvestNet dVPN Node Setup Script

A streamlined management script for deploying and operating an InvestNet dVPN node on Raspberry Pi (ARM64) systems. This script simplifies the installation of dependencies, binary management, and service orchestration.

Features

• Automated Dependency Management: Installs WireGuard packages and required tools.
• Architecture-Aware: Automatically downloads the optimized ARM64 binary for Raspberry Pi.
• Service Orchestration: Integrates with systemd for reliable background operation and auto-restart.
• Network Optimization: Handles IP forwarding, NAT (iptables/nftables), and dynamic egress interface detection.
• One-Command Management: Simple interface for initialization, starting, stopping, and status monitoring.

Prerequisites

• Hardware: Raspberry Pi (ARM64 architecture).
• OS: Linux (Debian/Ubuntu recommended).
• Access: Root or sudo privileges are required.
• Connectivity: Stable internet connection.

Quick Start

1. Download and Prepare the Script:

   chmod +x investnet-node.sh

2. Initialize the Node:

   sudo ./investnet-node.sh init

   This will install WireGuard, download the binary, and prompt for configuration (moniker, pricing, and keys).

3. Start the Node:

   sudo ./investnet-node.sh start

CLI Commands

The script follows a simple command structure: sudo ./investnet-node.sh <command>

Command	Description
init	Installs dependencies, downloads binary, and interactive node setup.
start	Configures networking and starts the node as a systemd service.
stop	Stops the node service and cleans up WireGuard interfaces.
restart	Restarts the node service.
status	Shows service status, logs, WireGuard peers, and NAT rules.
uninstall	Reversible: Stops node, removes service, data, and binary.

Configuration Details

• Binary Port: 18133 (TCP)
• WireGuard Port: 51820 (UDP)
• Data Directory: ${HOME}/.investnet-dvpnx
• Systemd Service: investnet-dvpn-node.service

Important

Backup Your Mnemonic! During the init phase, you will be given a mnemonic. Store this securely; if lost, your node's identity and potential earnings cannot be recovered.

Troubleshooting

Use the status command to diagnose issues:

sudo ./investnet-node.sh status

This command provides a comprehensive view of:

• Service health (systemctl status)
• Recent logs (journalctl)
• WireGuard interface state (wg show)
• IP Forwarding status
• NAT/Masquerade rules
