Description: 为了方便网络编程，90年代初，由Microsoft联合了其他几家公司共同制定了一套WINDOWS下的网络编程接口，即Windows Sockets规范，它不是一种网络协议,而是一套开放的、支持多种协议的Windows下的网络编程接口。本篇论文主要是介绍了在TCP/IP基础上利用winsock2对网卡进行编程，以达到网络流量监测的目的。论文首先介绍了TCP/IP协议，旨在介绍IP，TCP，UDP等比较重要的协议。主要是介绍IP头，TCP头，UDP头的特点，以便从IP头中可以获取源地址，目的地址，协议类型等信息。在随后的章节中提出了Socket的概念，Socket实际上提供了一个通信端口使所有拥有Socket的端口的计算机之间能够相互通信，在本论文中主要说明了socket的建立，监听和撤销的过程。具体到程序实现中，对网卡混杂模式的设置是通过原始套接字（raw socket）来实现的。为了让原始套接字能接受所有的数据，还需要通过将SOCK_RAW设置成SIO_RCVALL。对数据包的获取通过recv()函数来完成。最后要完成的工作就是对所捕获的IP数据包进行分析以提取出我们所需要的信息。在论文的最后是旨在说明进一步工作的展开.

Description: 相信各位都玩过SOCKET编程，用CSocket进行网络通讯非常方便，但有时想搞点底层点东西却非常麻烦，用windows的API最低也只能SOCK_RAW，顶多能看到IP层数据，如果想处理数据链路层的数据就无从下手了，幸好某天发现了winpcap东西。用了它处理底层的东西就非常方便。
winpcap主要有两个dll供程序员直接调用，pcap.dll和packet.dll，本程序主要使用pcap.dll.详细请看代码，本人也是刚接触WinPcap，所以一不定有一些错漏的地方，请各位大蝦不要见笑。
如果程序有编译不过去的地方，请务必先按装winPcap库，更新VC6的PlatformSDK

-I am sure we all played SOCKET programming, use CSocket for network communication is very convenient, but sometimes want to point at the bottom of things is very troublesome, with the lowest API of windows can only SOCK_RAW, at most able to see IP layer data, if you want to deal with data link layer data can never gain the upper hand, and fortunately found one day things WinPcap. Deal with it on the bottom of things very convenient. WinPcap has two main dll programmers for direct call, pcap.dll and packet.dll, the main use of this procedure pcap.dll. details please see the code, and I was a刚接触WinPcap, so one has some mistakes in the indeterminate place, please not a laughing stock of shrimp. If the program does not have to compile the last place, be sure to press installed Winpcap library updated VC6 the PlatformSDK

Description: 用VC++6.0的Sockets API实现一个聊天室程序.txt
VC++对网络编程的支持有socket支持，WinInet支持，MAPI和ISAPI支持等。其中，Windows Sockets API是TCP/IP网络环境里，也是Internet上进行开发最为通用的API。最早美国加州大学Berkeley分校在UNIX下为TCP/IP协议开发了一个API，这个API就是著名的Berkeley Socket接口(套接字)。在桌面操作系统进入Windows时代后，仍然继承了Socket方法。在TCP/IP网络通信环境下，Socket数据传输是一种特殊的I/O，它也相当于一种文件描述符，具有一个类似于打开文件的函数调用-socket()。可以这样理解：Socket实际上是一个通信端点，通过它，用户的Socket程序可以通过网络和其他的Socket应用程序通信。Socket存在于一个"通信域"(为描述一般的线程如何通过Socket进行通信而引入的一种抽象概念)里，并且与另一个域的Socket交换数据。Socket有三类。第一种是SOCK_STREAM(流式)，提供面向连接的可靠的通信服务，比如telnet,http。第二种是SOCK_DGRAM(数据报)，提供无连接不可靠的通信，比如UDP。第三种是SOCK_RAW(原始)，主要用于协议的开发和测试，支持通信底层操作，比如对IP和ICMP的直接访问。

The first University of California, Berkeley campus in UNIX for the TCP/IP protocol has developed an API, the API is well-known Berkeley Socket interface (socket). Into the Windows desktop operating system in the era after the Socket method inherited. In the TCP/IP network communication environment, Socket data transmission is a special kind of I/O, it is equivalent to a file descriptor, open the file with a similar function call in-socket (). Can interpret it this way: Socket is a communication endpoint, through which users can program the Socket and other network applications of Socket Communications. Socket exist in a "communication domain" (as described in the general thread o
