Raspberry and Reboot from fhem

[HarryT]

Hi I am trying to start a reboot of the rapsberry from  fhem with:

  system("sudo reboot &");

I tried this:
  http://ueberueck.com/index.php/fhem-hausautomatisierung/fhem-how-to-s/raspberry-aus-fhem-neu-starten

In my password file I have:
  fhem:x:999:20::/opt/fhem:/bin/bash

In groups I have:
  sudo:x:27:pi,fhem

In the fhem logging I get:

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

sudo: no tty present and no askpass program specified


Has anybody succeeded in getting this to work? If so, how?

Thanks

What do you have in /etc/sudoers ?

Hi

my /etc/sudoers: ( it is the standard version. as far as I see, it is sufficient to add fhem to the group sudoers)

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults        env_reset
Defaults        mail_badpass
Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root    ALL=(ALL:ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

%sudo   ALL=(ALL:ALL) ALL

That would need to be

Code Auswählen Erweitern


%sudo   ALL=(ALL:ALL) NOPASSWD: ALL


or better still

Code Auswählen Erweitern


fhem ALL=(root) NOPASSWD: /sbin/shutdown


[HarryT]

Cool

  fhem ALL=(root) NOPASSWD: /sbin/shutdown

worked.

BTW I guess adding fhem to the sudoers group is not necessary when this line is add to the sudoers file?

Thanks

Right.
