GNOME Nettool is a network information tool which provides user interfaces for some of the most common command line network tools, like ping, whois, traceroute, etc.

It was originally based on Mac OS X's network information tool, but has since then improved over so much that it now clearly exceeds Mac OS X's tool with more features and a better UI.
