[Winpcap-users] Retireving MAC Address

[Gianluca Varenni]

That will give you the IPv4/v6 address(es) of the adapter.

There's no pcap API to retrieve the MAC address of an adapter (if any).

You need to use the undocumented packet APIs to do that, the developer's pack for WinPcap has a sample showing how to do that, it's

WpdPack\Examples-remote\PacketDriver\GetMacAddress

  I am working on example to get the mac address of the adapter.

  Is this the way to get the mac address of the adapter...

  char curAddr[14];
  std::string macAddrFormat("%02x:%02x:%02x:%02x:%02x:%02x");
      /* Jump to the selected adapter */
      for(d=alldevs, i=0; i< inum-1 ;d=d->next, i++);

      printf("\n adrress %02x:%02x:%02x:%02x:%02x:%02x",
          d->addresses->addr->sa_data[0],
              d->addresses->addr->sa_data[1],
              d->addresses->addr->sa_data[2],
              d->addresses->addr->sa_data[3],
              d->addresses->addr->sa_data[4],
              d->addresses->addr->sa_data[5]);


  snprintf(&curAddr[0],18,macAddrFormat.c_str(),
                  d->addresses->addr->sa_data[0],
              d->addresses->addr->sa_data[1],
              d->addresses->addr->sa_data[2],
              d->addresses->addr->sa_data[3],
              d->addresses->addr->sa_data[4],
              d->addresses->addr->sa_data[5]);

  I have to compare the mac address from my config file and only allow that adapter to  capture packets...
  Please tell me how to do...its URGENT...

  Thanks in advance,,,,
