I used Mandrake Linux to install and run the Linux-based tools recommended in this book, and most Linux distributions and BSD or UNIX operating system can use these tools. There are many open source operating systems available as mentioned in Chapter 1. Most of them are UNIX-based, although they all have a graphical interface available called X-Windows, and window managers such as KDE and GNOME. These interfaces will be familiar to anyone who has used Microsoft Windows, but there are a few differences.

With a closed source product, you have no way of asking any questions or making any necessary upgrades to it once the company decides they don’t want to play anymore. Open source projects never die a final death. That’s not to say that they don’t go dormant. Projects go by the wayside all the time as the participants graduate or move on to a new stage of life. This is more prevalent in the smaller programs and tools.
