  • Issue of the topic:
    I created a script to wake my PC using Wake on LAN and suspend it (hibernate).
    When I execute the script from the command line everything works fine, passing “on” as a parameter turns the PC on, passing “off” as a parameter turns the PC off, and passing “status” as a parameter correctly displays the status of the PC (off for a while, while booting up, on when done)

However when I create a Thing with the exec binding only the “on” and “status” part work. I directed some log messages to a file in the “off” section and they are appended to the file correctly, but the hibernate command does not seem to come through.

here is the script:
#!/bin/bash

MAC_ADDRESS="XX:XX:XX:XX:XX:XX"
IP_ADDRESS="XXX.XXX.XXX.XXX"
USERNAME='user'
PASSWORD='password'

case "${1}" in
        [oO][nN])
                exec sudo etherwake $MAC_ADDRESS &> /dev/null
                ;;

        [oO][fF][fF])
                date >> /var/log/pascal.log
                echo "PC off " >> /var/log/pascal.log
                whoami >> /var/log/pascal.log
                echo "timeout 3 sshpass -p $PASSWORD ssh $USERNAME@$IP_ADDRESS shutdown /h " >> /var/log/pascal.log
                echo "$PATH" >> /var/log/pascal.log
                echo "" >> /var/log/pascal.log

                exec timeout 3 sshpass -p $PASSWORD ssh $USERNAME@$IP_ADDRESS shutdown /h &>/dev/null
                ;;

        [sS][tT][aA][tT][uU][sS])
                timeout 1 ping -c 1 -n $IP_ADDRESS &>/dev/null
                if [ $? -eq 0 ]; then
                        echo "ON"
                        exit 0
                else
                        echo "OFF"
                        exit 1
                fi
                ;;

        *)
                echo
                echo "Usage: pascals_pc <on|off|status>"
                echo
                exit 1
                ;;
esac

exit 0

I placed it in /usr/local/bin/ and added ALL ALL=NOPASSWD: /usr/sbin/etherwake to my sudoers file using visudo

Well in an effort to not look stupid I tried to fix the problem myself one last time. As it turns out I am stupid and someone created a post for stupid people like me: How to solve Exec binding problems .

My openhab user did not have my PC in its known host file. So I copied the file from the openhabian user.
