Pywol

A Wake-on-LAN tool written in Python.

Pywol allows for starting up WoL-enabled systems over a network¹, and can either be used as a CLI tool or imported for use in other Python code.

Installation

$ pip install pywol

Usage examples

As a CLI tool:

$ pywol 1A2B3C4D5E6F --v
Sent magic packet for '1A2B3C4D5E6F' to 255.255.255.255:9.
$
$ pywol 1A:2B:3C:4D:5E:6F --v --ip 192.168.1.5/24
Sent magic packet for '1A:2B:3C:4D:5E:6F' to 192.168.1.255:9.
$
$ pywol --help
Usage: pywol [OPTIONS] MAC_ADDRESS

  CLI for the Pywol package.

  Prefer to specify the IPv4 broadcast address of the target host's
  subnet over the default '255.255.255.255'.

  To automatically resolve the broadcast address of a subnet,
  specify the target host's IPv4 address along with its netmask. E.g.
  '192.168.1.5/24' or '192.168.1.5/255.255.255.0' --> '192.168.1.255'

Options:
  --ip_address, --ip TEXT  IPv4 broadcast address or host address with
                            netmask.  [default: 255.255.255.255]
  --port, --p INTEGER      Target port.  [default: 9]
  --verbose, --v
  --help                   Show this message and exit.

Imported for use in other code:

>>> from pywol import wake
>>>
>>> wake("1A2B3C4D5E6F", ip_address="192.168.1.255")
>>> wake("1A-2B-3C-4D-5E-6F", ip_address="192.168.1.5/24", return_dest=True)
('192.168.1.255', '9')
>>>

Why create another WoL tool?

I needed one and this was an opportunity to learn some stuff.
