xscreensaver and sonar
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\ -- *"The Truth is out there" - Spooky* -- *_ _ . . . . . . _ _ . _ _ _ _ . . . . _ . . . . _ _ . _ _ _ . . . . _ _ . _ . . _ . _ _ _ _ . _ . _ . _ . _ . * Computers: the final frontier.

It works fine with. Thank you Masaru Nomiya and Patrick Shanahan for your thoughts, I removed and then changed the SUID bit the way Masaru suggested, but no joy. When I run the sonar screensaver via xscreensaver-demo all I see is

I agree, not necessary, the ownership was already root:root and all the other screensaver apps are the same as well. One thing that is necessary is that I run xscreensaver-demo under my own user ID, not root, otherwise xscreensaver-demo complains about not being able to access display::0 if ran under root.
But, I checked that on Tumbleweed.
Unfortunately I am not using Tumbleweed, but OpenSuSE 15.4 (Boss won't let me use Tumbleweed, thinks it would be to unstable and changing too often) Thanks again, hope more ideas surface soon! Marc..

Start Xscreensaver-demo --> Settings --> Sonar Settings I have, it is set to ping our local subnet.

This means that the company can't use it、doesn't it? Yikes! 100 updates a day? I would think that is the definition of a sys-admins nightmare! LOL
Not sure if you were asking a rhetorical question about our company - Tumbleweed? No. Xscreensaver/Sonar? Don't care. Marc...

Don't care. I think that a stance like yours and Carlos's is the right way to deal with Linux. I am not sure if it is natural to deal with major updates of packages, but I am not sure if I am too diligent in dealing with minor updates. Aside from that, I use a package that is no longer maintained by openSUSE (and is not supported by any other distro), and I have a repository set up to update packages related to that software.
