Winpcap安装方法.doc

Winpcap安装方法Winpcap功能强大，效率高，使用方便，但是，使用前的准备工作要费一番功夫，步骤如下： 步骤1：安装驱动程序。下载WinPcap Driver和DLL并安装，安装后重启机器。 步骤2：下载wpdpack（Developers pack）。解压后会看到其中包含了docs、Include、lib、Examples等文件夹。 步骤3：在VC中设定Include目录及Library目录。具体做法：打开VC后，Tools-Option-Directories，在include files中添加wpdpackInclude目录（步骤2中得到的）；在Library files中添加wpdpackLib目录。 步骤4：Project-settings-Link，在Object/library modules中加上wpcap.lib。然后测试下：#include pcap.hvoid main() pcap_if_t *alldevs; pcap_if_t *d; int i=0; char errbufPCAP_ERRBUF_SIZE; /* 这个API用来获得网卡 的列表 */ if (pcap_findalldevs(&alldevs, errbuf) = -1) fprintf(stderr,Error in pcap_findalldevs: %sn, errbuf); exit(1); /* 显示列表的响应字段的内容 */ for(d=alldevs;d;d=d-next) printf(%d. %s, +i, d-name); if (d-description) printf(nttDescription: (%s)n, d-description); else printf( (No description available)n); if(i=0) printf(nNo interfaces found! Make sure WinPcap is installed.n); return; /* We dont need any more the device list. Free it */ pcap_freealldevs(alldevs);以上是在vc6里面的测试换成.net或者vs2005 ，可以更加简/* Copyright (c) 1999 - 2005 NetGroup, Politecnico di Torino (Italy)* Copyright (c) 2005 - 2006 CACE Technologies, Davis (California)* All rights reserved.* Redistribution and use in source and binary forms, with or without* modification, are permitted provided that the following conditions* are met:* 1.
