Anyone know how to get the xscreensaver app sonar to work (ping and show results) on 15.4 x64? I had done the recommended setup -

cd /usr/lib64/xscreensaver
chown root.root sonar
chmod +s sonar
ll sonar
-rwsr-sr-x 1 root root 137208 Jul  5 05:22 sonar

but no joy getting it to ping other hosts on my network and showing the results on the screensaver. The line from my .xscreensaver in my home dir looks like this -

  GL:                           sonar -root                                 \n\
