The purpose of this book is to explain the use of the GNU C and C++ compilers, gcc and g++. After reading this book you should understand how to compile a program, and how to use basic compiler options for optimization and debugging. This book does not attempt to teach the C or C++ languages themselves, since this material can be found in many other places (see section Further reading). Experienced programmers who are familiar with other systems, but new to the GNU compilers, can skip the early sections of the chapters "Compiling a C program", "Using the preprocessor" and "Compiling a C++ program". The remaining sections and chapters should provide a good overview of the features of GCC for those already know how to use other compilers.
The Linux Administrator's Security Guide
A computer is secure if you can depend on it and it's software to behave as you expect" - Practical UNIX and Internet Security Security is: availability, consistency, access control, data confidentiality, authentication. - http://www.sun.com/security/overview.html The principal objective of computer security is to protect and assure the confidentiality, integrity, and availability of automated information systems and the data they contain." - http://csrc.nist.gov/publications/secpubs/cslaw.txt . There are numerous definitions for "computer security", and most of them are correct. Essentially computer security means enforcement of usage policies, this must be done since people and software have flaws that can result in accidents, but also because someone may want to steal your information, use your resources inappropriately or simply deny you the use of your resources.
Security for Beginners
There is a saying in the security world that the only truly safe computer system is one that is disconnected from the network, switched off and buried six feet under ground. The sentiment may be somewhat true but it is hardly a practical solution to the problems we face today in protecting servers and desktops from outside intrusion. There are more computer systems connected to the internet either directly or via local area networks than at any time in the history of technology and the numbers are growing at a rapid rate. It seems that not a month goes by without another story in the news about the internal network of a major corporation being compromised by an intruder.

Beyond Linux From Scratch
Beyond Linux From Scratch (BLFS) is a project that continues where the LFS book finishes. It assists users in developing their systems according to their needs by providing a broad range of instructions for installing and configuring various packages on top of a base LFS system.Nearly anything! An LFS system is primed to become a system that fits whatever need you have. BLFS is the book that takes you down your own custom path. You could build an office workstation, a multimedia desktop, a router, a server, or all of the above! And the best part is you only install what you need.
Linux Knowledge Base and Tutorial
The Linux Knowledge Base and Tutorial (LINKBAT) is a web-based, unified knowledge base and tutorial with the primary goal of educating users on Linux. Please Note: In moving to PHPNuke many of the aspects that we were planning have either been put on hold indefinately, or discarding completely. For example, we are reconsidering using XML as an input source, instead, new material could be added using forms on the site. I have not made the changes to the Linkbat project documentation as I want to add a number of features to the Tutorialas quickly as possible. The KnowledgeUnit concepts all still apply, although we have adding and expanded them. In addition, we are currently using a MYSql database and not CSV text files.
Linux System Administrators Guide
The Linux System Administrator's Guide, describes the system administration aspects of using Linux. It is intended for people who know next to nothing about system administration, but who have already mastered at least the basics of normal usage. This manual doesn't tell you how to install Linux; that is described in the Installation and Getting Started document. See below for more information about Linux manuals. System administration covers all the things that you have to do to keep a computer system in usable order. It includes things like backing up files (and restoring them if necessary), installing new programs, creating accounts for users (and deleting them when no longer needed), making certain that the file system is not corrupted, and so on. If a computer were, say, a house, system administration would be called maintenance, and would include cleaning, fixing broken windows, and other such things.
Newbie Administrators Guide
We are relative Linux newbies (with Linux since Summer 1998). We run mostly RedHat and Mandrake -> the solutions might not be directly applicable to other Linux distributions (although most of them probably will be). Hope this helps; we try to be as practical as possible. Of course, we provide no warranty whatsoever. If you spotted a bad error or would like to contribute a part on a topic of your choice, we would like to hear from you. A complete reference for new Linux users who wish to set up and administer their own Linux home computer, workstation and/or their home or small office network. The answers are meant to be simple, with just sufficient detail, and always supported with a readily usable example. The work is still in progress, but we hope the Guide can be helpful already. We welcome your corrections, advice, criticism, links, translations, and CONTRIBUTIONS. Pls note that there are no ad banners on our pages.
and Optimizing Linux
I realized that a lot of people wanted to see it published for its contents, to get advantages out of it and see the power of this beautiful Linux system in action. A lot of time and effort went into the making of this book, and to ensure that the results were as accurate as possible. If you find any abnormalities, inconsistent results, errors, omissions or anything else that doesn't look right, please let me know so I that can investigate the problem or correct the error. Suggestions for future versions are also welcome and appreciated
Lately it seems that two topics crop up in conversation after conversation: the stock market and Linux. As for the stock market, I'm something of a pessimist. When friends and even perfect strangers continually recount their recent financial successes, I conclude that a stock market correction is overdue. (I've shifted my investments to bonds.) As for Linux, I'm considerably more - perhaps wildly - optimistic. When my realtor tells me about the TV feature on Linux she saw on CNN, I see it as a harbinger of Linux Spring. Like her, my cable TV repairman, and my colleague in the next office, you've probably heard about Linux from a magazine, radio or TV program, or a friend. You're wondering what Linux is about and whether you should give it a try. If so, particularly if you currently use Microsoft Windows, this book was written for you.
Advanced Linux Programming is published under the Open Publication License, Version 1, no options exercised. (Due to an oversight in final production, the copyright notice on the book is incorrect.) The full text may be downloaded from this site. Code samples in the book are covered by the GNU General Public License and are also available. The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
This book is intended for Linux users who want to learn more about the inner workings of Linux and how the various pieces of the Operating System fit together. This book will guide you step-by-step in creating your own custom build Linux system from scratch, using the source code of the software that we need. This book is also intended for Linux users who want to get away from the existing commercial and free distributions that are often too bloated. Using existing distributions also forces you to use the file system structure, boot script structure, etc. that they choose to use. With this book you can create your own structures and methods in exactly the way you like them (which can be based on the ones this book provides)
Linux Network Administrator's Guide
The idea of networking is probably as old as telecommunications itself. Consider people living in the Stone Age, when drums may have been used to transmit messages between individuals. Suppose caveman A wants to invite caveman B over for a game of hurling rocks at each other, but they live too far apart for B to hear A banging his drum. What are A's options? He could 1) walk over to B's place, 2) get a bigger drum, or 3) ask C, who lives halfway between them, to forward the message. The last option is called networking. Of course, we have come a long way from the primitive pursuits and devices of our forebears. Nowadays, we have computers talk to each other over vast assemblages of wires, fiber optics, microwaves, and the like, to make an appointment for Saturday's soccer match. In the following description, we will deal with the means and ways by which this is accomplished, but leave out the wires, as well as the soccer part.
Kernel module Programming Guide
This document is for people who want to write kernel modules. Although I will touch on how things are done in the kernel in several places, that is not my purpose. There are enough good sources which do a better job than I could have done. This document is also for people who know how to write kernel modules, but have not yet adapted to version 2.2 of the kernel. If you are such a person, I suggest you look at appendix to see all the differences I encountered while updating the examples. The list is nowhere near comprehensive, but I think it covers most of the basic functionality and will be enough to get you started.

Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense.

Debian GNU/Linux: Guide to Installation and Usage
We're glad to have this opportunity to introduce you to Debian! As we begin our journey down the road of GNU/Linux, we'd like to first talk a bit about what exactly Debian is - what it does, and how it fits in with the vast world of Free Software. Then, we talk a bit about the phenomenon that is Free Software and what it means for Debian and you. Finally, we close the chapter with a bit of information about this book itself.Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. At the core of an operating system is the kernel. The kernel is the most fundamental program on the computer: It does all the basic housekeeping and lets you start other programs. Debian uses the Linux kernel, a completely free piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. A large part of the basic tools that fill out the operating system come from the GNU Project, and these tools are also free.
The complete programmer's reference for the Motif toolkit now covers Motif 2.1, the latest release of Motif. It is a source for complete, accurate, and insightful guidance on Motif application programming. There is no other book that covers the ground as thoroughly or as well as this one. The book describes how to write applications using the Motif toolkit and goes into detail on every Motif widget class, with useful examples that will help programmers to develop their own code. Anyone doing Motif programming who doesn't want to have to figure it out on their own needs this book.

"Cluster" is an ambiguous term in computer industry. Depending on the vendor and specific contexts, a cluster may refer to wide a variety of environments. In general a cluster refers to a set of computer systems connected together. For the purposes of this book a cluster is set of computers which are connected to each other, and are physically located close to each other, in order to solve problems more efficiently. These types of clusters are also referred to as High Performance Computing (HPC) clusters, or simply Compute clusters.
Another popular usage of the term cluster is to describe High Availability environments. In this environment a computer system acts as the backup system to one or more primary systems. When there is a failure in a primary system, the critical applications running on that system are failed over to its designated backup system. Detailed usage and technology behind these types of clusters is outside the scope of this book.
The Big Online Book of Linux Ada Programming
The Linux operating system that was created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus, interested in the UNIX clone operating system Minix, wanted to create an expanded version of Minix with more capabilities. He began his work in 1991 when he released version 0.02 and invited programmers to participate in his project. Version 1.0 was released in 1994. The latest version is 2.4 and development continues. Linux uses GNU General Public License (GPL) and its source code is freely available to everyone. Linux distributions, CD-ROMs with the Linux kernel and various other software ready for installation, do not have to be free, but the Linux source code must remain available. Making source code available is known as 'open source'.
