This book covers the Linux Professional Institute™ family of certifications. There are three levels of LPI™ certification:

• Level 1: Junior Level Linux Professional.
• Level 2: Advanced Level Linux Professional.
• Level 3: Senior Level Linux Professional.

To obtain a certification, a candidate is required to pass exams and, for Level 2 and Level 3, to hold a lower-level certification from the LPI™. All LPIC candidates are encouraged to browse the documentation at the LPI™ website. The resources there will familiarize the candidate with many things that are outside the scope of this book (e.g. exam cost, testing centers, other training resources) you are also encouraged to register with the LPI™ so that you can access the candidate area.
The Detailed Objectives listed within each of the modules in this book have been reproduced from the LPI™ website with kind Permission. We are however, to make it clear that the Linux Professional Institute™ does not endorse the work contained within this book in any way whatsoever.

Audience

This book is written specifically for the LPIC candidate. It is based, as indeed is the exam, around a community driven documentation project known as "The Linux Documentation Project". Each module in the book, however, is organized around a particular subject. It is hence feasible for the casual reader to pick one particular module and study its material with a view to gain a better understanding of just that material. However, many of the modules - and in particular the Advanced modules - will assume a certain skill level. It is also feasible for a new Linux user to come here with a view to learn Linux. However, although such readers are very welcome, they may be better served by studying the following material, Linux Guide. The modules on the LPI Linux certification are heavily slanted toward up-and-coming sysadmins.

About this book

This book is organized so that each and every module can be accessed via the front page. This will be useful for readers who just wish to study or quickly gain information about one aspect of the exam syllabus. For exam candidates we have created an exam page which also has a table of contents that covers only the modules required for you to study for the various levels of the LPI™ . It is the hope of the contributors that the exam candidates will use the exam pages and their accompanying discussion pages to leave advice, tips and gotchas etc. for other exam candidates.
The Module pages will contain detailed objectives followed by an overview which in turn will be followed by section headings covering the module's syllabus. At the beginning of each section will be a list of prerequisite reading (hopefully all nicely formated). It is advisable to read them, although the linked articles may not be required knowledge to pass the exam. However, they should relate to the individual sections they are contained within.

Lastly, we are obviously looking for Authors, We encourage all positive edits even if it is just to correct a simple spelling mistake or fix a link; in short, "Every addition is very welcome."
