Why Linux?
Without question, Linux is rapidly becoming the operating
system of choice in many core areas of business. It is
transforming information technology in many exciting ways
from being used in products ranging from cell phones and
PDAs to cars and mainframe computers.
Like its many uses, Linux has a variety of printed and
electronic guides to show you what to do. The specialist
guides are highly detailed focusing on narrow areas of
excellence. The encyclopedic guides for beginners focus on
Linux fundamentals and then only introduce you to more
specialized topics. Unfortunately, there are few practical
texts in between that help you to transition from being a
beginner to having the confidence of an expert.
Why is this book necessary?
Most Linux "encyclopedias" are split in three sections,
an introductory section covering topics such as CD based
Linux installation, GUI interfaces and text editors; an
intermediate section covering Microsoft Office clone
productivity suites; and an advanced section covering
the topics most non-desktop-support IT professionals use
on a day-to-day basis.
Unfortunately the "advanced sections" in these guides
cover the underlying theory reasonably well, but often
are short on space to adequately cover detailed
configuration instructions. IT professionals frequently
have to purchase additional specialist books on each
topic.
Linux Quick Fix Notebook takes these "advanced sections"
and expands them sufficiently to provide a practical
tutorial guide on how to do basic configuration of many
popular Linux back-office applications with command by
command instructions.
To avoid confusion between the many flavors of Linux,
each with its own GUI interface, this guide exclusively
uses the command line to illustrate the tasks needed to
be done. It provides all the expected screen output when
configuring the most commonly used Linux applications to
help assure readers that they are doing the right thing.
The Notebook also includes many of the most commonly
encountered errors with explanations of their causes and
how to fix them.
Prerequisites
The book's format is aimed at proficient beginners,
students and IT professionals who often have to do advanced
tasks in which the underlying theory is understood, but the
commands to do it are forgotten or at the tips of their
tongues. To maintain it's appeal as a compact guide, only
the essential supporting theory is provided to help the end
user implement their projects under budget and ahead of
schedule.
A great deal of attention has been paid to troubleshooting
techniques that are often needed to remedy unexpected
behavior, and every chapter has real world practical
examples in the form of tutorials.
Because the readers are assumed to be exposed to the theory
of Linux, many of the introductory topics are not covered,
which provides room for much more coverage of the steps
needed to get the more difficult jobs done. Two to three
months of hands-on Linux experience is an ideal
pre-requisite. Additionally, basic Windows exposure to the
concept of sharing directories between servers is needed.
Approach
With this in mind, the persons most likely to be
interested in this book would be IT professionals and
consultants, power users, computer literate business owners;
community college and trade school professors and students;
and SOHO workers.
The book creates a typical departmental, small office or
home network and shows you how to set up the Linux servers
most businesses need. Three sections have been created to
make this process easier. The first starts as an
introduction to networking and extends into using Linux as a
main departmental server. The next section expands upon this
knowledge to show you how to create, manage and monitor your
own Linux-based Web site running on a simple DSL or cable
modem line. Finally, the third section covers more advanced
topics that will become invaluable as your Linux
administration role expands.
Explanations are given not as a lecturer, but as a trusted
and experienced coworker. The chapters have a logical flow
of information starting with concise backgrounders and
ending with a troubleshooting section.
Many of the topics are covered in Linux certification exams
making the book a valuable study guide for those seeking new
areas of professional development.
Summary
In summary this book
* Shows how to expand inexpensively an existing IT
investment in Windows using Linux
* Shows how to do this command by command.
* Is highly focused on being task-oriented.
* Illustrates how to create a simple network for small
business, corporate departments and homes.
* Provides an excellent networking familiarization and
troubleshooting guide
As the line between power users and administrators continues
to blur, as computers move from the data center to the
desktop, and as Linux and Windows gain equal footing in
business, it becomes harder to remember and do it all. This
is the guide that will give you enough time to eat lunch.
