Preface
I have tried to write a book that covers all HP-UX system and networking administration concepts. The book is divided into three parts. The first part consists of Chapters 1-11. It covers general UNIX concepts, user commands, and shell programming. The second part of the book covers HP-UX system administration and consists of Chapters 12-25. The third part consists of Chapters 26-36 and is dedicated to computer networking concepts and HP-UX network administration tasks. The book is divided into these three parts according to requirements of the HP-UX certification examination. This is also quite a logical way to present the material to a UNIX system administrator. At the end of each chapter, you will find chapter review questions to check your understanding of the material presented in the chapter. There are some sample test questions under "Test Your Knowledge," which will provide you an idea of which type of questions are going to be asked in the actual exam. I have tried to use a combination of simple and difficult questions in this part. Answers to the review questions are provided in Appendix A, and answers to the sample test questions are available in Appendix B.
While writing this book, I have tried to explain all system administration concepts in reasonable detail. Many examples are presented in each section of a chapter to help the user understand what happens when a particular command is executed. Commonly used command-line switches are also listed wherever appropriate. You will also find many screen shots showing what happens when you select a menu or press a button in the GUI windows. I have also tried to explain each system and network administration taskusing both command-line utilities and System Administration Manager (SAM). Most "old-fashioned" people would like to carry out many tasks using the command-line interface, which is also very important for passing the HP-UX certification examination.
The book is organized such that it progresses from simple-to-understand concepts to more-difficult and complicated ones. The same strategy is also implemented in each chapter. Figures, tables, and examples are presented wherever helpful to communicate the concept. The first few chapters contain more examples than the later ones to give a user a good start.
Another consideration in the organization of the book is logical relevance and order of the chapters. If an idea or concept depends on another concept, it is placed later in the book.
This book is intended to be the most comprehensive book on HP-UX. It not only covers the HP-UX certification exam, but it also serves as a reference book for even the most experienced HP-UX system administrators. The first part is designed with the most basic concepts so that anybody who is new to HP-UX can get the full benefit. The next two parts cover more-complicated system and network administration tasks. Both novice and experienced users will find interesting things here.
Part 1: Fundamentals of UNIX Systems
The first part is an introduction to the UNIX system. This is a more-general UNIX part and consists of login and logout procedure, file and directory manipulation, file editing, an introduction to the POSIX shell, and file security/permissions. This part shows the concepts of users and groups, which are common to all UNIX systems. UNIX commands related to all these topics are presented and the more commonly used options of these commands are discussed. This part also throws light on standard input/output and I/O redirection. Chapters 10 and 11 introduce shell programming concepts. Here you will find a number of shell programs, up to elaborate shell variables and flow control structures.
Part 2: HP-UX System Administration
The second part is the core HP-UX system administration part of the book. It fully covers all issues from the installation of HP-UX to managing devices, security, and system performance. The part starts with an introduction to System Administration Manager (SAM), which is a comprehensive HP-UX tool meant for system administration. Installation of HP-UX on a server or workstation is presented next. After that, you will gradually progress from basic to more-complex system configuration tasks, building a kernel, managing devices, adding/removing users, and concepts of the HP-UX file system.
Part 3: HP-UX Network Administration
The third part covers HP-UX network administration. It also contains general networking concepts such as the ISO-OSI reference model and TCP/IP networking. One chapter is dedicated to ARPA/Berkeley services. Then NFS, NIS, DNS, and NTP are covered.
How to Register for the HP-UX Certification Examination
You can register for the examination by calling Sylvan Prometric at 1-800-755-EXAM or directly at Website. You can also visit an authorized Sylvan Prometric Testing Center to get more information. A list of authorized testing centers is available at. More information is available on the HP Education Website.
Strategies for Taking the Test
You should take a practice test to estimate the time needed to answer all questions. Stay relaxed and have a good night's sleep before the test day. Keep the following things in mind for a successful examination:
- Reach the testing center at least 15 minutes before the scheduled starting time. You have to sign a few papers and show identification before you start the test.
- Have with you at least two pieces of personal identification: One of these must contain your photograph. For example, valid identification documents might be your driver's license and a credit card.
- You don't need to carry any paper or pencils with you.
- Carefully read each question before answering it.
- Try to answer the easy questions first. If a question is taking a long time, just mark it and move to the next question. You are allowed to go back to review your answers and answer any leftover questions. The first target should be to go through all the questions from start to finish.
- When selecting an answer, try to rule out some of the options. This will help you select the right answer.
- While reviewing your answers, try to read the question very carefully: You may have chosen a wrong answer because you have misunderstood the question.
