short_description: Send a magic Wake-on-LAN (WoL) broadcast packet
|
|
description:
|
|
- The C(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
|
|
type: str
|

broadcast:
|
|
description:
|
|
- Network broadcast address to use for broadcasting magic Wake-on-LAN packet.
|
|
default: 255.255.255.255
|
|
type: str
|
|
port:
|
|
description:
|
|
- UDP port to use for magic Wake-on-LAN packet.
|
|
default: 7
|
|
type: int
|
|
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).
