Windows下配置使用WinPcap

news 来源：原创 2024/5/1 3:28:15

0、前提

windows: win7 x64

WinPcap版本：4.1.3

WinPcap开发包：4.1.2

目标：在VS2010中配置使用winpcap 获取目标计算机中安装的网卡列表

1、下载

http://www.winpcap.org/

下载winpcap安装包和开发包

安装包安装完毕后，解压开发包到某个目录即可，开发包免安装。

3、在VS2010中配置

配置头文件和库文件

项目属性--VC++目录--包含目录 / 库目录

4、Demo

获取本机 / 远程机器上网卡的列表和相关数据

/*******************************
函数成功返回 0
失败返回     　-1

int 
pcap_findalldevs_ex(
char *source,                //本机/远程机器/文件
struct pcap_rmtauth *auth,   //目标机器用户名 密码
pcap_if_t **alldevs,         //输出参数，详细信息
char *errbuf                 //缓冲区 大小为PCAP_BUF_SIZE，函数失败时保存错误信息
);

pcap_findalldevs_ex函数指定本机时指定参数"rpcap://" 或 预定义宏PCAP_SRC_IF_STRING
当指定远程机器时需要按照"rpcap://host:port"的格式，默认端口号为2002
远程机器有密码时需要指定用户名和密码。

struct pcap_rmtauth
{
    
    int type;   //#define RPCAP_RMTAUTH_NULL 0  或   用户名密码验证 #define RPCAP_RMTAUTH_PWD 1
    

    char *username;  //用户名
    

    char *password;  //密码
};

// demo1.cpp : 定义控制台应用程序的入口点。

 * notes: The local/remote machine must install the Winpcap

          You must look out that the DEFAULT PORT  is 2002.
