I'm attempting to remotely wake a slave machine when the master boots up through a bash script using the etherwake command to send magic packets. Both OSs are Debian 8. The full code is written below:

/etc/init.d/etherwake

#!/bin/sh

#/etc/init.d/etherwake



### BEGIN INIT INFO

# Provides: etherwake

# Required-Start: $all

# Required-Stop: $local_fs $remote_fs $network $syslog

# Default-Start: 2 3 4 5

# Default-Stop: 0 1 6

# Short-Description: Start etherwake at boot time

# Description: Enable service provided by etherwake.

### END INIT INFO



ETHERWAKE=/usr/sbin/etherwake



case "$1" in



        start)

                echo  "Booting slaves through etherwake..."

                $ETHERWAKE <MAC Address>

                echo  "Finished booting all slaves."

                ;;



        stop)

                echo "Stop not implemented. Doing nothing"

                ;;



        restart|force-reload)

                $0 stop

                sleep 10

                $0 start

                ;;



        *)

                echo "Usage: /etc/init.d/etherwake {start}"

                exit 1

                ;;

esac



exit 0

After writing the script, I did:

1. chmod 755 /etc/init.d/etherwake


2. update-rc.d etherwake defaults


3. Reboot the system through shutdown -r now
   

I've also tried using /etc/rc.local in 3 different ways:

/etc/rc.local

#!/bin/sh -e

#

# rc.local



/etc/init.d/etherwake

etherwake <MAC Address>

/usr/sbin/etherwake <MAC Address>

exit 0

No luck whatsoever. When I run either /etc/rc.local or /etc/init.d/etherwake manually as root, everything works nicely. I thought it could be something with the permissions but as far as I read any script on /etc/init.d runs as root by default. What am I doing wrong?

Thanks in advance.

Edit:

I understand Debian 8 uses systemd instead of sysvinit. After setting everything upsystemctl -l status etherwake.service gives me:

● etherwake.service - Etherwake magic packet service

   Loaded: loaded (/etc/systemd/system/etherwake.service; enabled)

   Active: inactive (dead) since Fri 2016-09-30 16:30:56 BRT; 1min 33s ago

  Process: 824 ExecStart=/etc/init.d/etherwake start (code=exited, status=0/SUCCESS)

 Main PID: 824 (code=exited, status=0/SUCCESS)



Sep 30 16:30:56 hostname etherwake[824]: Booting slaves through etherwake...

Sep 30 16:30:56 hostname etherwake[824]: Finished booting all slaves.

And /etc/systemd/system/etherwake.service is:

[Unit]

Description=Etherwake magic packet service

Wants=network-online.target

After=syslog.service network.target network-online.target



[Service]

ExecStart=/etc/init.d/etherwake start



[Install]

WantedBy=default.target

Another thing I noticed is that running systemctl restart etherwake works as a charm.

The problem is that update-rc.d etherwake defaults maybe don't work. Try to enable service via systemctl, run:

systemctl enable etherwake
