eBooks de Linux

Desde que en 1991 Linus Torvalds publicara la primera versión del núcleo, los sistemas GNU/Linux han evolucionado drásticamente consiguiendo cada día más cuota de mercado, hoy en día, podemos encontrar sistemas GNU/Linux tanto en grandes servidores como en equipos domesticos, pero si hay un sector donde Linux ha ganado sobradamente la batalla a los sistemas propietarios es en el sector de los servidores, ya que permiten ofrecer todo tipo de servicios: servidores web, servidores de correo electronico, servidores de ficheros, servidores de telefonia IP. Los sistemas GNU/linux son los mas estables, seguros, aprovechan mejor el hardware del equipo, y ademas, podemos configurarlo y adaptarlo completamente a nuestras necesidades. Todas estas ventajas han permitido que sean los mas utilizados en los servidores de las empresas; y su cuota de mercado crece cada dia; De hecho, en la actualidad, la administracion de sistemas Linux es el sector con mas ofertas del mercado laboral informatico.El administrador de sistemas es el responsable de que el sistema informatico funcione correctamente y de modo seguro. Para ello, el administrador es una persona que posee amplios conocimientos en sistemas operativos, redes, programacion y como no, de seguridad informatica, el objetivo del libro es que aprenda, de una forma practica y sencilla, todo lo necesario para administrar el sistema operativo con mas futuro.

El presente libro trata de aclarar algunos aspectos sobre la administración de usuarios y grupos en el sistema operativo Linux.Estudiaremos la estructura y cómo administrar los ficheros: /etc/passwd, /etc/group, /etc/shadow, /etc/gshadow y /etc/adduser. conf.El objetivo principal de este libro es conseguir conclusiones y estudiar distintas situaciones con ejemplos para poder estudiar cada caso en particular y analizar los distintos resultados.

Este libro es una guía práctica dirigida a todos aquellos usuarios de Windows que desean comenzar a utilizar Linux. De forma práctica, se muestran las posibilidades de sustituir Windows por Linux y realizar todas las tareas que habitualmente se ejecutan con el PC. Para la confeccion de esta guia se ha elegido Mandriva, a pesar de que existe una gran variedad de distribuciones de GNU/Linux, por dos razones fundamentales: la facilidad de uso de su interfaz grafica y la gran cantidad de aplicaciones listas que incluye para su instalacion; todas las comentadas en el libro pueden instalarse en cualquier otra distribucion, lo que significa que los conceptos aprendidos sobre Mandriva resultan utiles en otras distribuciones populares como Ubuntu, openSUSE y Fedora. El libro trata inicialmente las caracteristicas de Linux, y como instalar y configurar Mandriva, despues repasa las principales aplicaciones incluidas en esta distribucion y, a continuacion, se centra en diferentes grupos: ofimatica y productividad, Internet, multimedia, graficos y fotografia digital. Con el objetivo de facilitar la transicion entre sistemas operativos, en cada aplicacion de Mandriva se busca su equivalente en Windows, de forma que permita al lector familiarizarse rapidamente con el sistema operativo.

Learn How to Make Wireless WorkWi-Fi, Bluetooth, and LoRa are technologies that power our world, but building with them isnt always straightforward. Connections drop, tutorials skip steps, and error messages dont always help resolve problems.Through a series of hands-on projects using Raspberry Pi and Linux, youll learn how wireless systems work, how to control them, and how to build tools that actually function in the real world. Each recipe is self-contained, reliable, and ready to adapt for your own projects.Among the books many projects, youll build: A BLE audio receiver for high-quality wireless sound A battery-powered LoRa node with miles of range A mesh Wi-Fi network that reroutes itself A signal strength display with a mini TFT screen A wireless intrusion detection system and captive portal Along the way, youll build a solid foundation in Linux networking, gain fluency in wireless protocols like 802.11, BLE, and LoRaWAN, and develop the confidence to design and deploy your own solutions.Each recipe is built around a wireless challenge youre likely to encounter and gives you the tools to solve it.Its wireless. Its Linux. And with this book, it finally makes sense.

Master the tools. Build the workflow. Own the shell.Effective Shell is the hands-on guide for developers who want to master the command linenot just to get around, but to build a fast, flexible, and portable development environment.This isnt a tour of shell commands. Its a blueprint for creating workflows that scale across machines, teams, and projects. Youll go from keystroke-level efficiency to composing powerful pipelines, writing reliable scripts, and automating common development tasks. Then youll take it further: managing your configuration with Git, customizing your shell setup, and working seamlessly across remote sessions using tools like Vim and tmux.By the end, your shell wont just be a tool; itll be an extension of your thinking.Youll learn how to: Find, filter, and reshape data using grep, regular expressions, and shell pipelines Write scripts that automate setup, configuration, and repetitive tasks Create Python-based CLI tools to pull and process structured data Manage your environment with Git and version-controlled dot files Edit quickly with Vim and multitask efficiently using terminal multiplexers Use AI tools to generate commands, debug faster, and enhance automation Rather than prescribing a one-size-fits-all toolkit, Effective Shell teaches you the tools, practices, and strategies to build a shell environment that fits the way you workefficient, portable, and entirely yours.Whether youre leveling up from the basics or refining your craft, this book will help you think clearly, automate confidently, and work more effectively in the shell.

Master the inner workings of your x64 Linux system and expand your OS expertise by writing your very own debugger using C++.If debuggers seem like magic to you, there is no better way to demystify them than to write your own. This book will show you exactly how to do it, walking you through the entire process of building a debugger for x64 Linux systems using C++. As go from an empty filesystem folder to a fully fledged debugger capable of setting breakpoints, stepping through code, manipulating variables, and more, youll learn how to: Attach to a process Read and write to registers Set hardware and software breakpoints Output disassembly Support multithreading and other tasks As you add features to your debugger, youll also pick up a wealth of knowledge about operating systems, compilers, software testing, and low-level programming that you can use in your day-to-day development.

Cloud Platforms provide VM images in the Linux OS as well. Linux has always been operated via terminal or shell through a keyboard and a terminal. Even with GUIs around, Linux continues to be operated from the shell.Linux VMs are also operated from the command line of your desktop via an SSH (secure shell) connection. They do not have a desktop environment or GUI installed by default. For Windows users migrating to Linux, a desktop environment would be more convenient to operate. Hence, various desktop environments can be set up on a Linux VM.Mostly we need to have Graphical User Interface GUI on the Linux Virtual Machine instance and to use Internet browser on it.This report will talk about the steps to install minimum required User Interface on VM (virtual machine) with Web Browser. We will work on installing a desktop environment on a Linux Virtual Machine on different Cloud Platforms. The book consists from the following sections:1. Generating SSH key for auto log in to Linux server2. Creating Google Cloud Linux Virtual Machine3. Logon to the Linux Virtual Machine4. Installing VNC server5. Installing XRDP server6. Installing a Graphical User Interface (GUI) for Linux Google Cloud instance and connecting to the server through VNC or RDP connection7. Quick guide to create a Linux virtual machine in Cloudsigma8. Quick guide to create a Linux Virtual Machine in the Microsoft Azure portal9. Quick guide to create a Linux Virtual Machine in Amazon AWS
