说明：  Linux网络编程是非常重要的，而且当我们一接触到Linux网络编程，我们就会发现这是一件非常有意思的事情，因为以前一些关于网络通信概念似是而非的地方，在这一段段代码面前马上就豁然开朗了。在刚开始学习编程的时候总是让人感觉有点理不清头绪，不过只要多读几段代码，很快我们就能体会到其中的乐趣了。下面我就从一段Proxy源代码开始，谈谈如何进行Linux网络编程。
(Linux Network Programming is very important, but when we reach a Linux Network Programming, we find this is a very interesting thing, because in the past some of the communications network concept specious, in this section of the code immediately before the gleam. At the beginning of the learning programming always make people feel a little disarray clue, but as long as the code to read paragraphs and soon we will be able to appreciate the fun. Now, I am from a Proxy source code, talk about how Linux Network Programming.)
