Thomas & Bob, thanks for your help, my backend is shutting down by
itself now. I removed the "sudo sh -c" and only have the sudo in front
of my /usr/local/bin/setwakeup, just as Wiki states. I also added the
/usr/bin/mythshutdown to my sudoer file. I just do not understand the
connection to mythshutdown, but I am happy it is working.
Thanks again,
Joel
