Wolmgr is a web application for turning hosts on/off from remote. It is based on Cherrypy to provide a restfull interface to send WOL, ping or shutdown commands. The commands are run by the fabric library (http://www.fabfile.org/).
Power On:
A wake on lan command is run on the local network.
Power Off:
For each type of host a plugin is called to handle the specific shutdown procedure:
- freenas_api: shutdown a freenas box by using its restfull API
- ssh_sudo(not implemented yet): to run a shutdown command through ssh
The above should be able to manage any host running freenas, linux, MacOS. There is no plan to implment plugins for other OSes.
Status check:
A ping is run periodically to show when the machine completed the power up/down.
Interface:
The interface is a simple web page based on JS, Ajax, JQuery and bootstrap to call the web application through REST actions.
Installation pre-requisite:
cherrypy fabric wakeonline tools
Installation:
git clone https://github.com/gbus/wolmgr.git
on a raspberry pi create a link to the wol command: sudo ln /usr/bin/wakeonlan /bin/wol
Configuration:
Rename config.py.example in config.py and edit it as per example (name, IP, MAC, type). Set the account info for the shutdown plugins in credentials.py.
Security:
The app doesn't currently offer any access protection. I have set up a vpn to limit the access to the service from remote. In future user/password login will be implemented.
The package is meant to be run in a linux environment, ideally on a credit card size board, (like raspberry pi) to keep the power consumption to a minuimum for a system supposed to be permanently on.
TODO
- Access to the interface through login
- tool to automatically configure passwordless ssh hosts and power them off
