最近買了一本好書

Network Programming with Perl

這一本不錯，有在台北天瓏找到中文版的

網路上也找到原文的電子書

下載
在於支持作者，我還是跑去買了一本

原文書要一千多，在天瓏的中文版，$680，就買了，厚度還是很厚

老闆說這本已經第九刷了

裡面除了解說IO::Socket以外，還說了物件的關係，<>角符號的使用、open()、sysopen()、read()、sysread()、以二進位方式開始檔案的binmode()……

還有很多網路protocol的使用方法
smtp,pop,ftp,imap,nntp,web,telnet……UDP程式設計、Broadcasting、Multicasting

還有用perl寫多執行緒應用程式……

很多很多，這本是一本很好的進階書

原文介紹：

Network Programming with Perl is a comprehensive, example-rich guide to creating network-based applications using the Perl programming language. Among its many capabilities, modern Perl provides a straightforward and powerful interface to TCP/IP, and this book shows you how to leverage these capabilities to create robust, maintainable, and efficient custom client/server applications.

The book quickly moves beyond the basics to focus on high-level, application programming concepts, tools, and techniques. Readers will find a review of basic networking concepts and Perl fundamentals, including Perl's I/O functions, process model, and object-oriented extensions. In addition, the book examines a collection of the best third-party modules in the Comprehensive Perl Archive Network, including existing network protocols for e-mail, news, and the Web.

The core of the book focuses on methods and alternatives for designing TCP-based client/server systems, and more advanced techniques for specialized applications. Some of the specific topics covered are: The Berkeley Sockets API; The TCP protocol and the IO::Socket API; FTP file-sharing service; The Net::Telnet module for adapting clients to interactive network services; SMTP, including how to create and send e-mails with multimedia attachments; HTTP and the LWP module for communicating with Web servers; Bulletproofing servers; Broadcasting and multicasting; and Interprocess communication with UNIX domain sockets.

Useful, working programs demonstrate ideas and techniques in action, including a real-time chat and messaging system, a program for processing e-mail containing MIME attachments, a program for mirroring an FTP site, and a Web robot.

Network Programming with Perl focuses on TCP/IP rather than just the common Web protocols. Modeled after the critically acclaimed TCP/IP Illustrated by W. Richard Stevens, this book achieves a level of detail far superior to most. It is an essential resource for network administrators and Perl programmers who are creating network applications.
