Public bug reported: Binary package hint: gnome-nettool
Just by coincidence I tried using Ping from Administration > Network Tools. It doesn't work! It says that I cannot ping anything, even though it works just fine if I do it in a terminal. I can also see with tcpdump that ping from this tool actually does work and nice replies are received also.
