Description: 该程序在 Windows 2000 Pro+SP4 下编译调试通过(Visual C++ 6.0 IDE环境)。
需要Winsock2支持。
1.该程序采用了winsock的原始套接字编程，实现了基本的Ping功能，使用方法:ping host,默认连续发送4个回显请求。
2.该程序中对ICMP首部的定义采用了非标准形式。即将选项数据中保存时间戳的头4个字节也定义为ICMP首部的一部分，这样ICMP首部就被定义为12个字节。这样主要做主要是为了编程的实现与理解上的方便。
3.根据习惯ICMP首部的标示符字段填充了进程ID。
4.该程序实现了在IP首部记录路由的RR功能，最多记录9个地址。
要实现的功能参数：
1.n 参数 设定发送回显请求的数量
2.l 参数 设定选项数据的填充字节数
3.t 参数 持续的发送回显请求，直到用户按下Control-C停止
4 w 参数 设定接收超时的时间，以毫秒为单位
参数的具体说明可以参考windows自带的ping程序-the program in Windows 2000 SP4 Pro compiler under through debugging (Visual C 6.0 IDE environment). Winsock2 need support. 1. The procedure adopted protocols of the original socket programming, the basic implementation of Ping function, Use : ping host, the default four consecutive send the request back significantly. 2. The procedure for the first ICMP using the definition of non-standard forms. Upcoming options to preserve the timestamp data for the first four bytes are defined as ICMP first part, the first such ICMP was defined as 12 bytes. This is done primarily to the realization of programming and understanding for it. 3. Under customary ICMP first marker Address field filled with the process ID. 4. The program achieved in the first record of IP routing RR functions, the most record

Description: java网络高级编程,这里包含本书的大部分源程序，读者需要调试程序时可以直接从这里拷贝到自己的相应目录下面。
本书中的每一章都单独作为一个目录，例如“chap1”中就包含了第一章中的源程序清单。
读者在查找文件时，首先到相应的目录下面去查找，如果没有则表明该章原文中有两个相同的文件名，则用户可以到该章相应的子文件夹中查找。例如读者查找“源程序清单7-6”，而该章中同时具有好几个文件名都命名为相同的MainFrame，则读者可以先到“chap5”目录下面去查找MainFrame.java，如果没有则在chap5目录下面的“7_6”子目录下面去查找该文件就可以了。
用户需要使用某个文件时，则需要将相应的文件处，同时注意文件中的package关键字（若存在package关键字，则需要将所有同package的文件拷贝到以该package为目录名的目录下面），然后用户就可以对源文件进行编译并运行得到本书中的运行结果。当然读者首先需要有一个Java的运行环境！
同时在每个文件夹下面如果再有其它类型的文件夹则是利用Jbuilder来生成的项目文件及相应的Java文件，读者可以利用Jbuilder直接打开该工程即可后编译运行！

Readers in search for documents, the first of the corresponding directory to locate, If not then show that the text of Chapter two of the same name, Users can then chapter corresponding to the sub-folder search. For example, readers find "source list 7-6" The chapter also has several documents were all named to the same MainFrame. Readers will be first. "chap5" directory to find MainFrame.java.
