Question

如何用vc++取得网卡的物理地址？

Answer 1

我想需要对底层协议如arp了解一些，应该对网络原理了解一些。

Answer 2

try SendArp, or you can get it from NetBIOS
// Note: Win2000 only
//   NOT NT 4.0, Win9x, WinME#pragma comment( lib, "Iphlpapi" )
#pragma comment( lib, "Ws2_32" )#include <windows.h>
#include <Iphlpapi.h>int main( ) {IPAddr ip = 0;
ULONG  mac = 0;
DWORD  error = 0;    DWORD dwSize = sizeof( ULONG) ;
    ip = inet_addr("192.168.0.100");
    //ip = inet_addr("xxx.xxx.xxx.xxx");
    error = SendARP(ip,0,&mac,&dwSize);    return 0;
}

Answer 3

athere_08(于斯) 
有什么好的建义

Answer 4

其实，我现在才学计算机网络，我看过网络中嗅探程序的原理，即修改mac网卡地址，我今天又看到说注册表中有mac地址，具体的查到了告诉你。

Answer 5

vc中应该有这样的函数来获得mac地址，到MSDN搜一下

Answer 6

netbios方法如下：bool GetAdapterInfo(int nAdapterNum, string & sMAC)
{
    // Reset the LAN adapter so that we can begin querying it 
    NCB Ncb;
    memset(&Ncb, 0, sizeof(Ncb));
    Ncb.ncb_command = NCBRESET;
    Ncb.ncb_lana_num = nAdapterNum;
    if (Netbios(&Ncb) != NRC_GOODRET) {
        char acTemp[80];
        ostrstream outs(acTemp, sizeof(acTemp));
        outs << "error " << Ncb.ncb_retcode << " on reset" << ends;
        sMAC = acTemp;
        return false;
    }
    
    // Prepare to get the adapter status block 
    memset(&Ncb, 0, sizeof(Ncb));
    Ncb.ncb_command = NCBASTAT;
    Ncb.ncb_lana_num = nAdapterNum;
    strcpy((char *) Ncb.ncb_callname, "*");
    struct ASTAT {
        ADAPTER_STATUS adapt;
        NAME_BUFFER NameBuff[30];
    } Adapter;
    memset(&Adapter, 0, sizeof(Adapter));
    Ncb.ncb_buffer = (unsigned char *)&Adapter;
    Ncb.ncb_length = sizeof(Adapter);
    
    // Get the adapter's info and, if this works, return it in standard,
    // colon-delimited form.
    if (Netbios(&Ncb) == 0) {
        char acMAC[18];
        sprintf(acMAC, "%02X:%02X:%02X:%02X:%02X:%02X",
                int (Adapter.adapt.adapter_address[0]),
                int (Adapter.adapt.adapter_address[1]),
                int (Adapter.adapt.adapter_address[2]),
                int (Adapter.adapt.adapter_address[3]),
                int (Adapter.adapt.adapter_address[4]),
                int (Adapter.adapt.adapter_address[5]));
        sMAC = acMAC;
        return true;
    }
    else {
        char acTemp[80];
        ostrstream outs(acTemp, sizeof(acTemp));
        outs << "error " << Ncb.ncb_retcode << " on ASTAT" << ends;
        sMAC = acTemp;
        return false;
    }
}int main()
{
    // Get adapter list
    LANA_ENUM AdapterList;
    NCB Ncb;
    memset(&Ncb, 0, sizeof(NCB));
    Ncb.ncb_command = NCBENUM;
    Ncb.ncb_buffer = (unsigned char *)&AdapterList;
    Ncb.ncb_length = sizeof(AdapterList);
    Netbios(&Ncb);    // Get all of the local ethernet addresses
    string sMAC;
    for (int i = 0; i < AdapterList.length; ++i) {
        if (GetAdapterInfo(AdapterList.lana[i], sMAC)) {
            cout << "Adapter " << int (AdapterList.lana[i]) <<
                    "'s MAC is " << sMAC << endl;
        }
        else {
            cerr << "Failed to get MAC address! Do you" << endl;
            cerr << "have the NetBIOS protocol installed?" << endl;
            break;
        }
    }    return 0;
}
