Reboot a computer from a ROS Node

I want to create a ROS service that will, when called using rosservice, reboot the computer.

Here is the code of my callback:

def reboot_callback(self, cmd):
    """
    Callback to reboot
    """

    res = TriggerResponse()
    res.success = True
    res.message = "Rebooting"
    os.system('reboot')
    return res

But, when I run rosservice call /reboot (Or whatever name the service is called), I get a Permission Denied Error due to the fact that ROS and Python isn't run as sudo and it needs admin privileges to be able to reboot the computer.

To have the correct privileges to reboot a computer from a ROS node, roscore and rosrun need to be ran from the root user.

Here's how I did it:

  • Get into the root user using sudo su

  • Source the ROS setup files and the catkin_ws files (source /opt/ros/kinetick/setup.bash && source catkin_ws/devel/setup.bash)

  • Run roscore and rosrun (or roslaunch if you have a launchfile) and you now can call your service.

Another way to do it is to use tmux.

  • Run tmux on the machine you want to reboot

  • ssh to the machine and run tmux attach

  • run whatever you needed to launch to try and reboot the machine with ros and it should work
