A Script to run on a RPI zero w to wake up machines if are dead depending on UPS status (On Batteries / On line)
requirements
apt get install wakeonlan logrotate apcupsd -y
Set up your apcupsd to either use usb to get the status or net.
put all files in folder /home/pi/awol then
chmod u+x /home/pi/awol/awol.sh
Add your machines in your Hostlist file
example
test:10.0.20.111:always|xx:xx:xx:xx:xx:xx
test2:10.0.20.211:online|xx:xx:xx:xx:xx:xx
test3:10.0.20.5:skip|xx:xx:xx:xx:xx:xx
Described as following title:ip:option|macaddress
test = title 10.0.20.111 = ip address of the host online|always|skip = Online will wake up the host only when ups isnt on batteries, always will wake up the host no matter what, skip will ignore waking the host and continue xx:xx:xx:xx:xx:xx = mac address of the host to be waken up
careful with : and |. There are there for a reason.
then add the following in your crontab
run crontab -e and paste
*/5 * * * * /home/pi/awol/awol.sh --silent
And now you check the hosts every 5 mins :)
The logs are under
/home/pi/awol/logs/awol.log
And rotating daily.
Happy wol magic :D
