0、前提

windows: win7 x64

WinPcap版本：4.1.3

WinPcap開發包：4.1.2

目標：在VS2010中配置使用winpcap 獲取目標計算機中安裝的網卡列表

1、下載

http://www.winpcap.org/

下載winpcap安裝包 和 開發包

安裝包安裝完畢后，解壓開發包到某個目錄即可，開發包免安裝。

3、在VS2010中配置

配置頭文件 和 庫文件

項目屬性--VC++目錄--包含目錄 / 庫目錄

4、Demo

獲取本機 / 遠程機器上網卡的列表和相關數據

char *errbuf                 //緩沖區 大小為PCAP_BUF_SIZE，函數失敗時保存錯誤信息
);

pcap_findalldevs_ex函數指定本機時指定參數"rpcap://" 或 預定義宏PCAP_SRC_IF_STRING
當指定遠程機器時需要按照"rpcap://host:port"的格式，默認端口號為2002
遠程機器有密碼時需要指定用戶名和密碼。

struct pcap_rmtauth

    int type;   //#define RPCAP_RMTAUTH_NULL 0  或   用戶名密碼驗證#define RPCAP_RMTAUTH_PWD 1
