module: wakeonlan
version_added: 2.2
short_description: Send a magic Wake-on-LAN (WoL) broadcast packet
description:
- The M(wakeonlan) module sends magic Wake-on-LAN (WoL) broadcast packets.
options:
mac:
description:
- MAC address to send Wake-on-LAN broadcast packet for
required: true
default: null
broadcast:
description:
- Network broadcast address to use for broadcasting magic Wake-on-LAN packet
required: false
default: 255.255.255.255
port:
description:
- UDP port to use for magic Wake-on-LAN packet
required: false
default: 7
author: "Dag Wieers (@dagwieers)"
todo:
- Add arping support to check whether the system is up (before and after)
- Enable check-mode support (when we have arping support)
- Does not have SecureOn password support
notes:
- This module sends a magic packet, without knowing whether it worked
- Only works if the target system was properly configured for Wake-on-LAN (in the BIOS and/or the OS)
- Some BIOSes have a different (configurable) Wake-on-LAN boot order (i.e. PXE first) when turned off
