WOL
Wake-on-LAN is a standard that allows a computer to be turned on or woken up by a network message called "Magic Packet".
Amahi supports waking up devices that have a dynamic or static DHCP leases in your network, under Setup > Networking.
These devices some times come with WOL enable. In many PCs, they need to be setup properly by enabling WakeOnLan in their BIOS. This setting has quite a few names in BIOS's out there. Here's a couple of them (find the one you need in the user manual of your motherboard/system):
- MAC Resume From S3/S4
- MACPME Power Up Control
- Power On By Onboard LAN
- Power Up By Onboard LAN
- Resume by LAN
- Resume By WOL
- Resume on LAN
- Resume on LAN/PME#
- Wake on LAN from S5
- Wake Up On LAN
- WakeUp by Onboard LAN
- WOL (PME#) From Soft-Off
To try it, go to Setup > Networking > Static IPs and unfold the row for the device that you want to wake up.

If you're trying to wake a remote Linux system, and it's not working, try executing this command on the remote Linux client:
ethtool -s eth0 wol g
Wake-On-LAN Server Application (Fedora 19 or greater)
Wake-On-LAN Server is an application that enables users to wake client devices in their network through their Amahi server. The inspiration and core scripts of Wake-On-LAN Server are Jeremy Blum's work (Raspberry Pi Remote Wake-On-LAN Server). Secure login and MySQL database have been added to increase the programs functionality as a App.
To manually install, Open terminal as root:
- Install WOL dependency
yum -y install wol
- Create a webapp called wolserver
- Navigate to the wolserver directory
cd /var/hda/web-apps/wolserver
- Download Wake-On-LAN Server (Alpha)
wget https://github.com/thegillion/WOL-server-w-sql/archive/master.zip
- Unzip the file
unzip WOL-server-w-sql-master.zip -d html
- Create an SQL database called wolserver
hda-create-db-and-user wolserver
- Import the tables from the download file.
mysql -uwolserver -pwolserver wolserver < html/wolserver.sql
- Change file ownership to apache:users
chown -R apache:users html
That's it for setup. You are now ready to configure the application for your devices.
The administrator login is:
Name: admin
Password: admin
Wake a computer Passphrase (change by editing config.php):
wakemeup
To access the app outside of the network, refer to Hosting a single web app, hosting multiple web apps, or hosting webapps (alternative) guidance.
If interested in "Sleep-On-LAN" for a Windows computer, see Jeremy Blum's page. Install the SleepOnLan client for this capability.
