Today was the first expose to public of the wakeup tool. It's available on github here https://github.com/alexbumbacea/wakeup/
The tool is designed for companies that want to reduce the amount of power consumer by the computers while employees are not using them, but also offer possibility during VPN connections to access the machines.
It requires wake-on-lan to be enabled from bios and, for the auto-discovery functionality, it requires that computer would have Windows Shares enabled( it uses netbios scans ). Also computer may be added manually to the list.
Currently documentation and interface are still in work, but the core functionality is working.
