Sebastopol, CA--As the use of Linux by large corporations and the
general public increases, so has the demand for qualified Linux
administrators and technicians. Consequently, there has also emerged a
need for a means by which to objectively measure these administrators'
skills. Understandably, there is some controversy surrounding
certification of Linux professionals; some fear that certification will
give an edge in the job market to less experienced candidates who hold
the appropriate certification over more experienced candidates who lack
certification. While these fears are not unfounded, the benefits of a
certification program would seem to far outweigh them if Linux is to
continue to expand into the mainstream.
"Over the last few years the status of Linux has changed significantly
in the press and popular opinion," says Jeffrey Dean, author of
Certification in a Nutshell (O'Reilly, US $39.95). "Once a niche
solution at best, it's now a strategic technology for major
corporations like IBM and Dell. It has also popularized Open Source and
Free Software, and has the attention of Microsoft. I don't see this
trend slowing anytime soon, so the need for qualified Linux
administrators is likely to rise. The LPI program serves this growing
market with an affordable, objective certification. This book prepares
candidates with detailed information and examples."
The LPI (Linux Professional Institute) certification program is one of
a number of programs formed over the last few years to provide
certification for Linux administrators. As Dean explains, each of the
existing programs approaches the problem of certifying Linux
administrators in a different way. While Dean's book covers the range
of topics that will be useful to all system administrators who use
Linux, his focus is on preparing for the LPI certification examination.
Deans says, "The LPI is vendor-neutral and a not-for-profit
organization, which make it unique in the Linux certification market.
As for the future, as a certified professional myself, I hope the
market fully embraces these skill sets."
Dean's book is divided into two parts, one for each of the LPI Level 1
Exams (Level 1 is aimed at junior to mid-level Linux administrators).
Each part features a summary of the exam, a highlighter's index, labs,
suggested exercises, and practice exams.
Part 1 covers the General Linux Exam 101, which mainly tests knowledge
of facts, including commands and their common options, important file
locations, configuration syntax, and common procedures. Part 1 includes
- GNU and Unix commands
- Devices, Linux file systems, and the file system hierarchy standard
- Boot, initialization, shutdown and run levels
- Administrative tasks
- Hardware and architecture
Part II of the book covers General Linux Exam 102, which tests a
slightly broader range of administration skills, including basics such
as PC architecture and Linux installation, GUI (X Windows)
customization, and networking. Part II includes the following:
- Linux installation and package management
- The Linux kernel
- Text editing, processing, and printing
- Shells, scripting, programming, and compiling
- Networking fundamentals
- Network services
Certification In a Nutshell is designed to help system
administrators prepare for the LPI certification exams, but even
experienced Linux administrators can benefit from a full review of this
material. The tutorial-style approach will help newbies learn more
about their Linux systems. Dean adds, "This book makes no assumptions
about Linux experience, and will be very effective for those coming
from other computer systems such as Windows or mainframes."

and Windows NT operating systems.
