Unix操作系统是目前一些常用平台（如Mac OS X 和Linux）的基础。本书将讨论Unix的基础知识以及日益流行的Sun Solaris和BSD平台的基础知识。 首先，读者将学习Unix术语、核心概念、方法以及怎样登陆和退出系统，然后开始定制工作环境并学习命令，最后将学习如何管理进程、处理安全事务、使用Perl脚本自动处理任务，以及如何安装Unix程序和备份数据等内容。 本书涵盖了Unix操作系统的各个方面的内容，其独特之处在于包含了Unix的派生系统和一个独有的转换章节，深入讨论了Unix的基础知识以及日益流行的Sun Solaris和BSD平台的基础知识。 本书适用于任何对Unix操作系统感兴趣的读者。虽然本书是一本入门级图书，但对于那些已经具有一定Unix知识的读者，仍颇具实用价值，另外，如果读者希望将Mac OS或Windows中的相关知识转换到Unix或其派生版本中，本书也可以作为一本优秀的参考手册。

This is THE guide to UNIX network programming APIs. Whether you write Web servers, client/server applications, or any other network software, you need to understand networking APIS-especially sockets in greater detail than ever before. You need UNIX Network Programming, Volume 1, Third Edition. In this book, the Authors offer unprecedented, start-to-finish guidance on making the most of sockets, the de facto standard for UNIX network programming with APIs - as well as extensive coverage of the X/Open Transport Interface (XTI).

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them.

编写更好的软件：30年UNIX开发经验的结晶！ 本书是作者封笔30年后历时5年创作而成，是一部难得的软件工程方面的佳作。作者首次将哲学、设计模式、工具、文化和传统结合在一起，使得UNIX成为世界上最好且最创新意义的软件，并展示了如何将其拓展到Linux和当今的开源（open-source）运动中。通过取自最主要的开源项目中的示例，作者向UNIX和Linux编程人员展示了如何更巧妙地创建软件，使其更雅致、更灵巧、更具可重用性且具有更长的生命期。 Raymond借鉴了以下13位UNIX先锋人物的观点： Ken Thompson，UNIX的发明者 Ken Arnold，4BSD UNIX的创建者之一，也是《The Java Programming Language》的作者之一。 Steven M.Bellovin，Usenet的创始人之一，也是《Firewalls and Internel Security》的作者之一。 Stuart Feldman，贝尔实验室UNIX开发组成员，也是《make》和《f77》的作者。 Jim gettys和Keith Packard，X视窗系统的主创人员。 Steve Johnson，《yacc》和《Portable C Compiler》两书的作者。 Brian Kernighan《The C Programming Language》、《The UNIX Programming Environment》及《The Practice of Programming》等几本书的作者之一，也是awk编程语言的作者之一。 David Korn，korn shell的创始人，也是《The New Korn Shell Command and Programming Language》的作者。 Mike Lesk，贝尔实验室开发组成员，ms宏包、tbl和refer工具以及lex与UUCP的作者 Doug Mcllroy，贝尔实验室研究组主任，UNIX即诞生于此；同时他还是UNIX管道的发明者。 Marshall Kirk McKusick，4.2BSD快速文件系统的开发者，4.3BSD和4.4BSD开发组的领导。 Henry Spencer，早期UNIX开发者中的佼佼者，他创建了getopt、第一个开源字符串库以及用于4.4BSD的正则表达式引擎。 “Reading this book has filled a gap in my education. I feel a sense of completion, understand that UNIX is really a style of community. Now I get it, at least I get it one level deeper than I ever did before. This book came at a perfect moment for me, a moment when I shifted from visualizing programs as things to programs as the shadows cast by communities. From this perspective, Eric makes UNIX make perfect sense。” 作者简介： Eric S.Raymond多年前即从事NUIX开发。他以开源社区巡回大使的身份而著称。他在著名的《The Cathedral and the Bazaar》、《大教堂和市集》中发表了开源运动的宣言，并且还编著了《The New Hacker's Dictionary》一书。

TCP/IP Illustrated, Volume 1, Second Edition, is a detailed and visual guide to today’s TCP/IP protocol suite. Fully updated for the newest innovations, it demonstrates each protocol in action through realistic examples from modern Linux, Windows, and Mac OS environments. There’s no better way to discover why TCP/IP works as it does, how it reacts to common conditions, and how to apply it in your own applications and networks. Building on the late W. Richard Stevens’ classic first edition, author Kevin R. Fall adds his cutting-edge experience as a leader in TCP/IP protocol research, updating the book to fully reflect the latest protocols and best practices. He first introduces TCP/IP’s core goals and architectural concepts, showing how they can robustly connect diverse networks and support multiple services running concurrently. Next, he carefully explains Internet addressing in both IPv4 and IPv6 networks. Then, he walks through TCP/IP’s structure and function from the bottom up: from link layer protocols–such as Ethernet and Wi-Fi–through network, transport, and application layers. Fall thoroughly introduces ARP, DHCP, NAT, firewalls, ICMPv4/ICMPv6, broadcasting, multicasting, UDP, DNS, and much more. He offers extensive coverage of reliable transport and TCP, including connection management, timeout, retransmission, interactive data flow, and congestion control. Finally, he introduces the basics of security and cryptography, and illuminates the crucial modern protocols for protecting security and privacy, including EAP, IPsec, TLS, DNSSEC, and DKIM. Whatever your TCP/IP experience, this book will help you gain a deeper, more intuitive understanding of the entire protocol suite so you can build better applications and run more reliable, efficient networks.

Richard Stevens (Addison-Wesley). This book includes lots of realistic examples, and I find it quite helpful when I have systems programming tasks to do." --RS/Magazine "This is the definitive reference book for any serious or professional UNIX systems programmer. Rago has updated and extended the original Stevens classic while keeping true to the original." --Andrew Josey, Director, Certification, The Open Group, and Chair of the POSIX 1003.1 Working Group For over a decade, serious C programmers have relied on one book for practical, in-depth knowledge of the programming interfaces that drive the UNIX and Linux kernels: W. Richard Stevens' Advanced Programming in the UNIX(R) Environment. Now, Stevens' colleague Stephen Rago has thoroughly updated this classic to reflect the latest technical advances and add support for today's leading UNIX and Linux platforms. Rago carefully retains the spirit and approach that made this book a classic. Building on Stevens' work, he begins with basic topics such as files, directories, and processes, carefully laying the groundwork for understanding more advanced techniques, such as signal handling and terminal I/O. Substantial new material includes chapters on threads and multithreaded programming, using the socket interface to drive interprocess communication (IPC), and extensive coverage of the interfaces added to the latest version of the POSIX.1 standard. Nearly all examples have been tested on four of today's most widely used UNIX/Linux platforms: FreeBSD 5.2.1; the Linux 2.4.22 kernel; Solaris 9; and Darwin 7.4.0, the FreeBSD/Mach hybrid underlying Apple's Mac OS X 10.3. As in the first edition, you'll learn through example, including more than 10,000 lines of downloadable, ANSI C source code. More than 400 system calls and functions are demonstrated with concise, complete programs that clearly illustrate their usage, arguments, and return values. To tie together what you've learned, the book presents several chapter-length case studies, each fully updated for contemporary environments. Advanced Programming in the UNIX(R) Environment h

    If you are an experienced C programmer with a working knowledge of UNIX, you cannot afford to be without this up-to -date tutorial on the system call interface and the most important functions found in the ANSI C library. Richard Stevens describes more than 200 system calls and functions; since he believes the best way to learn code is to read code,a brief example accompanies each description. Building upon information presented in the first 15 chapters, the author offers chapter-long examples teaching you how to create a database library, a PostScript printer driver, a modem dialer, and a program that runs other programs under a pseudo terminal. To make your analysis and understanding ofthis code even easier, and to allow you to modify it, all of the code in the book is available via UUNET. Advanced Programming in the UNIX Environment is applicable to all major UNIX releases, especially System V Release the latest release of 4.3BSD, including 386BSD. These real-world implementations allow you to more clearly understand the status of the current and future standards,including IEEE POSIX and XPG3.

本书全面深入地讲述了套接口API网络编程的既成事实标准，对X／open传输接口API也作了广泛的介绍。本书从对套接口API的综合讨论开始，论述了基本编程内容后，即转入高级套接口编程的相关主题，包括IPv4与IPv6的互操作性；UNIX域协议、非阻塞I／O、路由套接口、广播、多播、线程、原始套接口、数据链路访向等，对于客户一服务程序的各种设计方法也作了完整的探讨。在叙述X／Open传输接口API时，还对记这种设备驱动机制作了深入分析。在附录中又给出了IPv6、ICMPV6、虚拟网络等新内容。 本书内容详尽且具权威性，几乎每章都提供精选的习题，是计算机和网络专业高年级本科生和研究生的首选教材。本书也可作为网络研究和开发人员的自学教材和参考书。
