Start / Stop Process as root with System Exec in RT Linux

[Oliver_15]

Hi, 

Is there a way of allowing LabVIEW to start/stop a process that needs root privileges? Attached is a snippet of the test code where I'm trying to command;

/etc/init.d/ntpd stop             #Stop NTP Daemon

I've tried using su command but receive error: su: must be run from a terminal.

Hardware: sbRIO-9651

Software: LV2015 SP1

Hi Oliver_15,

A reasonable approach is to install and configure sudo to allow you, as the lvuser user, to run the script (see: https://forums.ni.com/t5/NI-Linux-Real-Time-Discussions/Is-it-possible-to-close-and-re-open-RTEXE-th...)

Thanks. Just what I needed.
