powertool 0.3.0

powertool

Python utility to wake up(wol) and suspend Linux machines remotely

Free software: MIT license

Features

Wake up remote machines using hostname/ip.
Suspend remote machines using hostname

Wake on lan (WOL)
Wake up feature uses WOL magic packet. Since mac addresses are hard to remember/use, this tool lets you wake up or suspend machines
by their name or IP.

First register your machines
powertool register -b 192.168.1.255 aa:bb:cc:dd:ee:ff you@host

-b Broadcast_IP - this is the subnet on which your machine’s ip is. If your machine’s ip is 192.168.1.xxx, then this is 192.168.1.255(default)
aa:bb:cc:dd:ee:ff - your machines’ mac address. You can find this on your machine or on the router’s device list.
you@host - your username on the remote host - this is used by the sleep function to do a passwordless ssh and run pm-suspend.

register saves machine details so that you can later do this:
powertool wol host
powertool sleep host

register just saves machine details to a ~/.powertool as a json file.

Sleep/suspend
Sleep/suspend feature has quite a few dependencies

you should have password-less ssh to the remote host. There are a lot of
guides on the internet on how to set this up - like this one
http://www.linuxproblem.org/art_9.html. Verify that it works by running ssh
user@host - you should not be prompted for a password.
You should have pm-utils package on your remote machine
http://manpages.ubuntu.com/manpages/precise/man8/pm-action.8.html
Your user should be able to run sudo pm-suspend without being prompted for
password. To set this up, login to the remote machine and do the following:
sudo visudo
# add the following - where user is your username on the remote machine
user ALL=(ALL) NOPASSWD: /usr/sbin/pm-suspend
