1、安装winpcap
地址：http://www.winpcap.org/install/default.htm =》安装软件
地址：http://www.winpcap.org/archive =》下载package开发包wpdPack
a) 执行安装包，这样你的机子就能运行winpcap程序了
b)解压开发包，在VC6.0的Tools-->Option-->Directories的Include
fils 和library files加入winpcap的include和lib目录
c)在项目属性页中：配置属性->C/C++->预处理器->预处理器定义，增加;WPCAP;HAVE_REMOTE;
d)在项目属性页中：配置属性->链接器->命令行->附加选项对应的文本框中增加：“wpcap.lib
ws2_32.lib Packet.lib”
如果出现missing';'这种的，需要转到错误处，注视掉它们即可；
2、winpcap使用教程
a)一个简单的例子，获取网络设配器基本信息：
#include
#pragma comment( lib, "wpcap.lib" )// 库文件
int main()
{
pcap_if_t *alldevs;//定义要获取的设备组
pcap_if_t *d;//定义单个设备组
int i = 0;//下面的for循环用
char errbuf[PCAP_ERRBUF_SIZE];//定义错误信息
/* 获取本地所有网络设配器的列表 */
if(pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL, &alldevs, errbuf) == -1)
{
// 获取失败，打印错误信息
fprintf(stderr, "Error in pcap_findalldevs_ex: %s\n", errbuf);
exit(1);
}
/* 循环打印设配器列表 */
for(d = alldevs; d != NULL; d = d->next)
{
// 打印设配器的名字
printf("%d. %s", ++i, d->name);
// 打印设配器的描述信息
if (d->description)
printf("(%s)\n", d->description);
else
printf("(No description available)\n");
}
// 没有任何设配器列表
if(i == 0)
{
printf("\nNo interfaces found! Make sure Winpcap is installed.\n");
return -1;
}
// 释放设配器列表指针的内存
pcap_freealldevs(alldevs);
// 防止命令窗口一闪而过
char c = getchar();
return 0;
}
b) 获取详细的网络设配器的信息：
#include "pcap.h"
// #include
// #pragma comment(lib,"ws2_32.lib")
#pragma comment(lib,"wpcap.lib")
#define IPTOSBUFFERS 12
void ifprint(pcap_if_t *d);
char * iptos(u_long in);
int i = 0;
int main()
{
pcap_if_t * alldevs;
pcap_if_t * d;
char errbuf[PCAP_ERRBUF_SIZE];
/*取得列表*/
if(pcap_findalldevs(&alldevs,errbuf) == -1)
{
exit(1);
}
/*输出列表*/
for(d=alldevs;d != NULL;d=d->next)
{
ifprint(d);
}
if(i==0)
{
printf("\nNo interfaces found!Make sure WinPcap is installed.\n");
return 0;
}
pcap_freealldevs(alldevs);
char g=getchar();
return 0;
}
void ifprint(pcap_if_t *d)
{
pcap_addr_t *a;
printf("%d.%s",++i,d->name);
if(d->description)
{
printf("\tDescription:(%s)\n",d->description);
}else{
printf("\t(No description available)\n");
}
printf("\tLoopback:%s\n",(d->flags & PCAP_IF_LOOPBACK)?"yes":"no");
for (a=d->addresses;a != NULL;a=a->next)
{
printf("\tAddress Family:#%d\n",a->addr->sa_family);
switch (a->addr->sa_family)
{
case AF_INET:

if(a->addr)
{

}

{

}
if(a->broadaddr)
{

}
if(a->dstaddr)
{
printf("\tDestination Address:%s\n",iptos(((struct sockaddr_in *)a->dstaddr)->sin_addr.s_addr));
}
break;
default:
printf("\tAddressFamilyName:Unknown\n");
break;
}
}
}
char * iptos(u_long in)
{
static char output[IPTOSBUFFERS][3*4+3+1];
static short which;
u_char *p;
p = (u_char *)∈
which=(which+1==IPTOSBUFFERS?0:which+1);
sprintf(output[which],"%d.%d.%d.%d",p[0],p[1],p[2],p[3]);
return output[which];
}
c) 开始针对网卡进行抓包
