Genre: Computers

The most complete, authoritative technical guide to the FreeBSD kernel’s internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition’s content is completely new, and another one-third has been extensively rewritten. Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel’s current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down–from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking. This Second Edition • Explains highly scalable and lightweight virtualization using FreeBSD jails, and virtual-machine acceleration with Xen and Virtio device paravirtualization • Describes new security features such as Capsicum sandboxing and GELI cryptographic disk protection • Fully covers NFSv4 and Open Solaris ZFS support • Introduces FreeBSD’s enhanced volume management and new journaled soft updates • Explains DTrace’s fine-grained process debugging/profiling • Reflects major improvements to networking, wireless, and USB support Readers can use this guide as both a working reference and an in-depth study of a leading contemporary, portable, open source operating system. Technical and sales support professionals will discover both FreeBSD’s capabilities and its limitations. Applications developers will learn how to effectively and efficiently interface with it; system administrators will learn how to maintain, tune, and configure it; and systems programmers will learn how to extend, enhance, and interface with it. Marshall Kirk McKusick writes, consults, and teaches classes on UNIX- and BSD-related subjects. While at the University of California, Berkeley, he implemented the 4.2BSD fast filesystem. He was research computer scientist at the Berkeley Computer Systems Research Group (CSRG), overseeing development and release of 4.3BSD and 4.4BSD. He is a FreeBSD Foundation board member and a long-time FreeBSD committer. Twice president of the Usenix Association, he is also a member of ACM, IEEE, and AAAS. George V. Neville-Neil hacks, writes, teaches, and consults on security, networking, and operating systems. A FreeBSD Foundation board member, he served on the FreeBSD Core Team for four years. Since 2004, he has written the “Kode Vicious” column for Queue and Communications of the ACM. He is vice chair of ACM’s Practitioner Board and a member of Usenix Association, ACM, IEEE, and AAAS. Robert N.M. Watson is a University Lecturer in systems, security, and architecture in the Security Research Group at the University of Cambridge Computer Laboratory. He supervises advanced research in computer architecture, compilers, program analysis, operating systems, networking, and security. A FreeBSD Foundation board member, he served on the Core Team for ten years and has been a committer for fifteen years. He is a member of Usenix Association and ACM.

Publisher: No Starch Press
ISBN: 9781593278939
Release Date: 2018-10-02
Genre: Computers

This updated edition of Michael W. Lucas' definitive volume on FreeBSD-based systems adds coverage of modern disks, the ZFS filesystem IPv6, redesigned jail and packaging systems, and virtualization, among dozens of new features added in the last 10 years. FreeBSD is the muscle behind companies like Netflix and EMC. Any place where someone does heavy lifting on the Internet, you'll find FreeBSD. This newly revised edition of Absolute FreeBSD brings FreeBSD's strengths to bear on your problems and covers FreeBSD's newest features, all in the inimitable style that has made author Michael W. Lucas' system administration books so popular. Any computer system is only as good as the system administrator's knowledge. Absolute FreeBSD teaches you everything you need to know about managing FreeBSD systems, from installation, configuration, and taking the system from "just working" to "working well." A cohesive focus on service delivery and best practice means that you can apply much of the book to other operating systems. Absolute FreeBSD dives deep into server management, taking you beyond just making things work and into understanding why they work. You'll learn: * How to best install FreeBSD to meet your needs * Which filesystem to use in your environment * How to back up and restore critical data * How to tweak the kernel, and when not to * Network configuration, from activating interfaces to selecting congestion control algorithms * How to manage UFS, ZFS, and other critical filesystems * FreeBSD's software packaging system, including how to build your own package repository * How and when to upgrade * Techniques to build your own FreeBSD * Advanced security features like blacklistd and packet filtering * How to monitor and adjust performance * Container-style virtualization with jails * Diskless systems * Panic management and bug reporting With Absolute FreeBSD readers will get the solid introduction they need while fans of the earlier editions will expand their skills even further.

grep kurz & gut ist die erste deutschsprachige Befehlsreferenz zu grep, dem mächtigen Such- und Filterungswerkzeug unter Unix. Jeder, der sich ausführlich zu den Möglichkeiten, die in grep stecken, informieren möchte, ist mit diesem Buch bestens bedient. Er erfährt, wie viele alltägliche Aufgaben mit grep ausgeführt werden können, von der Mail-Filterung über geschicktes Log-Management bis hin zur Malware-Analyse. Der Befehl grep stellt viele verschiedene Möglichkeiten bereit, Textstrings in einer Datei oder einem Ausgabestream zu finden. Diese Flexibilität macht grep zu einem mächtigen Tool, um das Vorhandensein von Informationen in Dateien zu ermitteln. Im Allgemeinen ist der Befehl grep nur dafür gedacht, Textausgaben oder Textdateien zu durchsuchen. Sie können auch Binärdateien (oder andere Nicht-Textdateien) durchsuchen, aber das Tool ist in dem Fall eingeschränkt. Tricks zum Durchsuchen von Binärdateien mit grep (also die Verwendung von String-Befehlen) werden ebenso in grep kurz & gut aufgezeigt. Sollte der Leser bereits mit der Arbeit mit grep vertraut sein, hilft ihm grep kurz & gut dabei, seine Kenntnisse aufzufrischen und mit grep besonders effizient zu arbeiten. Für grep-Einsteiger ist das vorliegende Buch eine hervorragende Möglichkeit, grep von Grund auf zu lernen und klug anzuwenden.
