Linux.com focuses on security with this tutorial on "hping".

You can test the security of your network in a number of ways. One is to hire your own hacker and see if he can get in. Another (and maybe more practical) way is to install hping. As the name suggests, hping is based on the ping utility, but the two applications are used in different ways.

The distributors include Debian, Fedora, Gentoo, and Red Hat.
