wol-proxy

wol-proxy is a simple cross-platform CLI tool and HTTP server for sending Wake-on-LAN (WoL) packets over your network.

Use it as a local utility or run it on a remote VM to expose WoL via an HTTP API.

📦 Installation

npm install -g wol-proxy

🚀 Usage

1. Start the server

To start the proxy:

wol-proxy

It starts an HTTP server on port 3000 by default.

Override the port:

PORT=8080 wol-proxy

The server listens on all interfaces (0.0.0.0).

📬 Send Wake-on-LAN Request

Make a POST request to /wake with a JSON body:

Example using curl:

curl -X POST http://<proxy-ip>:3000/wake \
  -H "Content-Type: application/json" \
  -d '{"mac": "00:11:22:33:44:55", "ip": "10.0.0.100", "port": 9}'

Successful Response:

{ "success": true }

🔧 Request Options

| Field | Required | Description | |---------|----------|-------------| | mac | ✅ Yes | Target device MAC address (e.g. "f8:01:b4:68:bc:22") | | ip | ❌ No | Broadcast IP (default: 255.255.255.255) | | port | ❌ No | UDP port (default: 9) |

🧪 Quick Test

wol-proxy &
curl -X POST http://localhost:3000/wake \
  -H "Content-Type: application/json" \
  -d '{"mac": "00:11:22:33:44:55"}'

🔐 Security

This server is unauthenticated by default.
To secure it:

• Use a reverse proxy (NGINX or Apache) with IP whitelisting or auth
• Restrict access using a firewall or run behind a VPN

🖥 Development

Clone and run locally:

git clone https://github.com/CLDMV/wol-proxy.git
cd wol-proxy
npm install
node index.js

🛠 Running as a System Service (Ubuntu, CentOS, Fedora, etc.)

After installing wol-proxy globally with npm, it will automatically attempt to install a systemd service during post-install (on compatible Linux systems).

If successful, you’ll see a confirmation message and can start the service immediately.

✅ 1. Manual Setup (if automatic setup fails or is skipped)

You can still manually enable the service using the bundled .service file:

sudo cp $(npm root -g)/@cldmv/wol-proxy/wol-proxy.service /etc/systemd/system/wol-proxy.service

This copies the service file from the global npm module into the systemd directory.

✅ 2. Enable and start the service

sudo systemctl daemon-reload
sudo systemctl enable wol-proxy
sudo systemctl start wol-proxy

🔍 Check service status

sudo systemctl status wol-proxy

📋 View logs

journalctl -u wol-proxy -f

wol-proxy will now run in the background and start automatically at boot.
