Simple Wake on LAN Script (PHP)

A small and simple Wake on LAN helper script written in PHP, designed for use with Google Remote Desktop.

This script allows you to remotely power on a PC in sleep or hibernate mode using a web browser on a smartphone or other device.

What is this?

This is a Wake on LAN (WOL) script for users of Google Remote Desktop.

While Google Remote Desktop is widely used,
it does not provide a built-in way to power on a remote PC. This script fills that gap.

---

What does it do?

• Sends a WOL (Magic Packet) to a target PC
• Allows remote power-on from a web browser
• Works well together with Google Remote Desktop

---

How do I use it?

If you manage a website, this should be self-explanatory.

1. Configure the required settings in config.php
2. Specify hostnames (or IP addresses) and MAC addresses
3. Set write permissions for the log file wol.log

To find the MAC address, run:

ipconfig /all

If you are already using Google Remote Desktop,
you should be able to check it remotely.

Prerequisites

• If the target PC does not have a fixed global IP address, a DDNS service is required.
• Configure your router to allow Wake on LAN packets.

Router settings:

• Protocol: UDP
• Port:
  • 9 for LAN
  • 2304 for WAN (recommended)
• Destination: Broadcast address within the LAN
  • Example: 192.168.0.255 for 192.168.0.0/24

NIC (Ethernet) settings:

• Wake on Magic Packet: Enabled
• Wake on pattern match: Enabled
• Shutdown Wake Up: Enabled
• Enable PME: Enabled

Windows:

• Disable Fast Startup
• Enable Wake on LAN in BIOS / UEFI

Depending on the BIOS/UEFI, the PC may not wake from a full shutdown. In such cases, use Hibernate mode.
