Es gibt Maker, die vor dem Raspberry Pi zurückschrecken, weil ihnen Linux fremd oder zu kompliziert erscheint. Das Betriebssystem Raspbian - die Linux-Version für den Raspberry Pi - ist jedoch erst einmal nichts anderes als ein weiteres Tool im Werkzeugkasten des Makers. Dieses Buch will Sie damit vertraut machen. Die Vorliebe für Raspbian kommt bei Makern nicht von ungefähr und es gehört inzwischen dazu wie Schraubendreher und Hammer in der Werkstatt. Linux ist so leistungsfähig, dass Sie sich vielleicht sogar dazu entschließen, es für Ihre täglichen Aufgaben am Computer einzusetzen! Das Buch befasst sich mit Linux speziell im Hinblick auf die Bedürfnisse von Makern. Die vermittelten Grundlagen helfen Ihnen, Ihre Projekte weiterzuentwickeln und Neues zu entdecken. Die Themen reichen vom Laden des Betriebssystems über die Fehlerbehebung bis zur Projektvorbereitung: - Raspbian und andere populäre Linux-Distributionen installieren - Code für Skripte schreiben, um Hardware undArduino zu steuern - Linux-Befehle, -Systeme und -Prozesse kennenlernen - GPIO-Pins auf Ihrem Raspberry ansteuern - ein IFTTT-Applet und andere Cloud-Dienste nutzen - einen virtuellen Raspberry Pi unter Windows, macOS oder Linux betreiben Nutzen Sie die Freiheiten und endlosen Möglichkeiten von Raspbian und Linux!
Firewalls, Network Address Translation (NAT), network logging and accounting are all provided by Linux´s Netfilter system, also known by the name of the command used to administer it, iptables. The iptables interface is the most sophisticated ever offered on Linux and makes Linux an extremely flexible system for any kind of network filtering you might do. Large sets of filtering rules can be grouped in ways that makes it easy to test them and turn them on and off. Do you watch for all types of ICMP traffic--some of them quite dangerous? Can you take advantage of stateful filtering to simplify the management of TCP connections? Would you like to track how much traffic of various types you get? This pocket reference will help you at those critical moments when someone asks you to open or close a port in a hurry, either to enable some important traffic or to block an attack. The book will keep the subtle syntax straight and help you remember all the values you have to enter in order to be as secure as possible. The book has an introductory section that describes applications,followed by a reference/encyclopaedic section with all the matches and targets arranged alphabetically.
In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn´t kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does. This edition of the book covers Version 2.6, which has seen significant changes to nearly every kernel subsystem, particularly in the areas of memory management and block devices. The book focuses on the following topics: - Memory management, including file buffering, process swapping, and Direct memory Access (DMA) - The Virtual Filesystem layer and the Second and Third Extended Filesystems - Process creation and scheduling - Signals, interrupts, and the essential interfaces to device drivers - Timing - Synchronization within the kernel - Interprocess Communication (IPC) - Program execution Understanding the Linux Kernel will acquaint you with all the inner workings of Linux, but it´s more than just an academic exercise. You´ll learn what conditions bring out Linux´s best performance, and you´ll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments.

You´ve experienced the shiny, point-and-click surface of your Linux computer now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell. Along the way you´ll learn the timeless skills handed down by generations of gray-bearded, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book´s short, easily-digestible chapters, you´ll learn how to: Create and delete files, directories, and symlinks Administer your system, including networking, package installation, and process management Use standard input and output, red
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
