I like to send the following command to an other Raspberry to switch ob the power outlet for my printer:
http://:@192.168.178.24:44000/dev/sps/io/VI64/1

It dosen't work if I just use the command. Is there any other possibility?

It works with
curl -m 2 http://:@192.168.178.24:44000/dev/sps/io/VI64/1

I also want to send a shutdown command to OptoPi. But shutdown -h now needs root privileges. Which command does OctoPrint use?
