Requirements

Any cpython (common python) implementation from 2.4 to 3.X.

Probably it also works with jython, ironpython and pypy but I haven’t personally tested on those implementations.

Installation

pip install awake

Or with the old easy_install

easy_install awake

Or with the source

python setup.py install

Upgrading from 0.X to 1.0

Make sure the previous CLI script awake.py gets removed from the script installation path after the upgrading, e.g. in linux /usr/bin/ the new cli interface is just awake and if the file awake.py exists at the same level of the script then the new awake going to try to fetch the required modules from the old cli script awake.py.

CLI Examples

Wake-on-lan a group of computers in the current network:

awake 1c:6f:65:31:aa:5f 1c6c2531e051 3f.6c.25.31.e0.55 3b-6c-21-31-e0-41

which is equivalent to:

awake -f ~/list_of_macs

and in the file list_of_macs have one MAC per line or use the -s option.

list_of_macs content:

1c:6f:65:31:aa:5f # web1
1c6c2531e051      # web2
# The rest
3f.6c.25.31.e0.55
3b-6c-21-31-e0-41

The format of the MAC is flexible in the sense that can use any character to group the digits of the MAC, except for the reserved character # for comments.

Wake-on-lan a computer or group of computers in a external network

For this situation, you need to forward a port in your router, for example to forward 9999 to 9 in the local network o 7777 to 7, check the documentation if your router or modem. After the port has been configured you can use DDNS to have a reference to the current ip address of your router/modem and use awake in this way:

awake -d myhouse.homedns.com -p 9999 -f ~/file_with_my_macs

or use any other option, the important here is to use the -d and -p options to specify the destination to send the magic packet.

Alternative method to invoke awake

Awake can be used calling the module directly from python:

python -m awake

Is the same interface as the installed script awake, this is very useful in platforms like windows, when the PythonXX/Scripts is not set in the PATH.

As a library

The real functionality of the wake-on-lan is provided from a small function that is implemented in the provided module awake.wol:

send_magic_packet(mac, broadcast='255.255.255.255', dest=None, port=9)
    Send  a "magic packet" to the given destination mac to wake up
    the host, if `dest` is not specified then the packed is broadcasted.

Apart from the awake script the WOL functionality can be easily integrated in your python programs with a simple call to the function like:

from awake import wol

def sysadmin_function_x(mac, *args):
    # some stuff...
    wol.send_magic_packet(mac)
    # some more stuff...

Tests

The tests are designed to be executed with the python unittest module, you can run the tests from the folder test:

cd test
python -m unittest discover

In case that you want to run the tests in python < 2.7, you will need the unittest2 module.

The general recommended process to develop is using virtualenv and after creating the environ just run:

./environ/bin/python setup.py install
./environ/bin/python -m unittest discover
