More info: As the error comes from ping, I tried this:
$ ping -b 72.249.171.160 ping: invalid option -- 'b' ?: not implemented So it should be coming from ping itself? Can someone second that? What is the -b option? I don't see it in my "man ping" page. this might be useful (both contains /bin/ping): inetutils-ping: Installed : 2:1.5.dfsg.1-8ubuntu1 iputils-ping: Installed : (none) -- gnome-nettool ping fails with ping: invalid option -- 'b' https://bugs.launchpad.net/bugs/299920 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
