Managing Wake on LAN with set_wake_on_lan

The set_wake_on_lan command in the ChromeOS Shell enables users to manage the Wake on LAN (WoL) feature for Ethernet devices. WoL allows devices to be powered on remotely by sending a network packet, commonly known as a magic packet.

Usage

bash set_wake_on_lan <true | false>

Parameters

  • true: Enable the Wake on LAN feature.
  • false: Disable the Wake on LAN feature.

Examples

1. Enable Wake on LAN

bash set_wake_on_lan true

This enables the WoL feature for the connected Ethernet device. The device can now be powered on remotely using a magic packet.

2. Disable Wake on LAN

bash set_wake_on_lan false

This disables the WoL feature, preventing the device from being powered on remotely.

Additional Information

  • Effectiveness: Changes take effect after reconnecting to the Ethernet network but are not persistent across system restarts.
  • Use Case: Wake on LAN is commonly used in enterprise environments for remote device management and maintenance tasks.
  • Compatibility: Ensure the Ethernet hardware and network support WoL functionality before enabling it.

Best Practices

  1. Verify Hardware Compatibility

  2. Confirm that your Ethernet device and network support Wake on LAN before enabling the feature.

  3. Reconnect After Configuration

  4. Disconnect and reconnect the Ethernet cable to apply the WoL setting.

  5. Use for Remote Management

  6. Enable WoL to facilitate remote power-on capabilities for managed devices, especially in enterprise setups.

The set_wake_on_lan command is a convenient utility for managing remote power capabilities, enhancing the flexibility and efficiency of networked devices.
