Was trying to start/stop wview from wviewgmt/system_status.php  but does not respond.
Did a search and found that root permission must be given in /etc/sudoers file, but am unable to find the posting 
that states how to do this in detail as stated. Could I get direction for doing this or point me to the posting of instructions.
thank you. Tim

to allow the http server run the start/stop script (only) as superuser when the wviewmgmt button is pressed, add line to end of file of form:
_www ALL = NOPASSWD: /opt/local/etc/init.d/wview
where, in my case on a mac:
 * the user owning the http server is _www (www-data on my backup ubuntu server)
 * my start/stop command file is /opt/local/etc/init.d/wview (often /usr/local/etc/init.d/wview on my backup ubuntu server)
cheers

Thank you for the reply. Wview is installed on a raspberry pi 3 presently. I don't see the /usr/local/etc/init.d file that you speak of. Is it a different file on raspbian Jessie or a different command as well? Thank you

platform-dependent location. not familiar with pi. could try /etc/init.d/wview.
if not there, just search for the startup file, probaby called wview:
 $ find / -name “wview*” -print

I have a Raspberry for my wview installation, and can confirm Graham's hunch that the wview commands are at /etc/init.d/wview

Beware. Don't use leafpad to edit /etc/sudoers! 
I've just scrambled my /etc/sudoers by doing so, and now have a bit of a mess to clean up. :-(
