Written by the creator of Webmin, this book explains how to use the most popular Webmin modules to perform common administration tasks on a Linux system such as adding users, configuring Apache, setting up NFS file sharing and managing the Sendmail mail server.Each chapter covers a single server or service, and is broken down into sections that list the steps required to carry out certain tasks using Webmin. The chapters also provide some background on the service being configured and the basic concepts behind it.Cameron also explains how to develop your own Webmin modules and themes, and includes a complete reference for the API that is available to module writers. He dissects each of the standard modules and themes so that programmers thinking of writing their own can see how they work, and what kind of coding style is used.Webmin is a browser-based user interface for performing system administration tasks on Linux and Unix servers.Part of the Bruce Perens' Open Source Series
