Unlike some operating systems, Linux doesn t try to hide the important bits from you it gives you full control of your computer. But to truly master Linux, you need to understand its internals, like how the system boots, how networking works, and what the kernel actually does. In this completely revised second edition of the perennial best seller How Linux Works, author Brian Ward makes the concepts behind Linux internals accessible to anyone curious about the inner workings of the operating system. Inside, you ll find the kind of knowledge that normally comes from years of experience doing things the hard way. You ll learn: How Linux boots, from boot loaders to init implementations (systemd, Upstart, and System V) How the kernel manages devices, device drivers, and processes How networking, interfaces, firewalls, and servers work How development tools work and relate to shared libraries How to write effective shell scripts You ll also explore the kernel and examine key system ta

The Linux Programming Interface (TLPI) is the definitive guide to the Linux and UNIX programming interface the interface employed by nearly every application that runs on a Linux or UNIX system. In this authoritative work, Linux programming expert Michael Kerrisk provides detailed descriptions of the system calls and library functions that you need in order to master the craft of system programming, and accompanies his explanations with clear, complete example programs. You´ll find descriptions of over 500 system calls and library functions, and more than 200 example programs, 88 tables, and 115 diagrams. You´ll learn how to: Read and write files efficiently Use signals, clocks, and timers Create processes and execute programs Write secure programs Write multithreaded programs using POSIX threads Build and use shared libraries Perform interprocess communication using pipes, message queues, shared memory, and semaphores Write network applications with the sockets API While The
The job of Linux systems administrator is interrupt-driven and requires constant learning in byte-wise chunks. This book gives solutions to modern problems-even some you might not have heard of-such as scripting LDAP, making Mac clients play nice with Linux servers, and backup, security, and recovery scripts. Author Juliet Kemp takes a broad approach to scripting using Perl and bash, and all scripts work on Debian or Red Hat lineage distributions. Plus, she dispenses wisdom about time management, dealing with desperate colleagues, and how to avoid reinventing the wheel! Learn how to love LDAP scripting and NFS tuning Make Perl serve you: don´t be enslaved by Perl Learn to change, craft, and feel empowered by recipes that change your life
Kali Linux has not only become the information security professional´s platform of choice, but evolved into an industrial-grade, and world-class operating system distribution-mature, secure, and enterprise-ready. Through the decade-long development process, Muts and his team, along with countless volunteers from the hacker community, have taken on the burden of streamlining and organizing our work environment, freeing us from much of the drudgery. They provided a secure and reliable foundation, allowing us to concentrate on securing our digital world. An amazing community has built up around Kali Linux. Every month, more than 300,000 of us download a version of Kali. We come together in online and real-world training rooms and grind through the sprawling Offensive Security Penetration Testing Labs, pursuing the near-legendary Offensive Security certifications. We come together on the Kali forums, some 40,000 strong, and hundreds of us at a time can be found on the Kali IRC channel. We gather at conferences and attend Kali Dojos to learn from the developers themselves how to best leverage Kali. However, the Kali team has never released an official Kali Linux manual, until now. In this book, we´ll focus on the Kali Linux platform itself, and help you understand and maximize Kali from the ground up. The developers will walk you through Kali Linux features and fundamentals, provide a crash course in basic Linux commands and concepts, and then walk you through the most common Kali Linux installation scenarios. You´ll learn how to configure, troubleshoot and secure Kali Linux and then dive into the powerful Debian package manager. Throughout this expansive section, you´ll learn how to install and configure packages, how to update and upgrade your Kali installation, and how to create your own custom packages. Then you´ll learn how to deploy your custom installation across massive enterprise networks. Finally, you´ll be guided through advanced topics such as kernel compilation, custom ISO creation, industrial-strength encryption, and even how to install crypto kill switches to safeguard your sensitive information. Whether you´re a veteran or an absolute n00b, this is the best place to start with Kali Linux, the security professional´s platform of choice.
Program audio and sound for Linux using this practical, how-to guide. You will learn how to use DSPs, sampled audio, MIDI, karaoke, streaming audio, and more. Linux Sound Programming takes you through the layers of complexity involved in programming the Linux sound system. Youll see the large variety of tools and approaches that apply to almost every aspect of sound. This ranges from audio codecs, to audio players, to audio support both within and outside of the Linux kernel. What Youll Learn Work with sampled audio Handle Digital Signal Processing (DSP) Gain knowledge of MIDI Build a Karaoke-like application Handle streaming audio Who This Book Is For Experienced Linux users and programmers interested in doing multimedia with Linux. Jan Newmarch is Head of ICT (Higher Education) at Box Hill Institute, Adjunct Professor at Canberra University and Adjunct Lecturer in the School of Information Technology, Computing and Mathematics at Charles Sturt University. He is interested in more aspects of computing than he has time to pursue, but the major thrust over the last few years has developed from user interfaces under Unix into Java, the Web and now into general distributed systems. Jan has developed a number of publicly available software systems in these areas. Right now, he is looking at sound for Linux systems and programming the Raspberry Pis GPU.
The first barrier that a new Linux user has to face is the overwhelming number of flavors that this operating system has. These flavors are commonly known as distros (from distribution), and to date there are more than three hundred active distros to choose from. So, how to choose one? You can choose the most popular at the moment, or take heed of what your friend says, but are you sure that this is the one that you need? Making the wrong decision on this matter is behind a good number of disappointments with this operating system. You need to choose the distro that is right for you and your needs. Introducing Linux Distros teaches you the pros and the cons of the most frequently used distros in order to find the one that is right for you. You will explore each distro step by step, so that you dont have to endure hours of web surfing, countless downloads, becoming confused by new concepts and, in the worst cases, reading complex and marathon installation guides. You will benefit from the authors long-term experience working with each distro hands on, enabling you to choose the best distro for your long-term needs. Linux offers us a wonderful open source alternative to proprietary software, and using Introducing Linux Distros you can decide how to best make it work for you.
