Can a website detect a persons mac address?

No its not possible to get mac address through the website. It means you can search the computer and website or explorer have not right about it .

But try these may be

1.
First you can use Gethostbyaddr() to get remote host's name
then you can use Netbios()(setting ncb.command =ncbstat)
then you can get the mac address of remote host's net adapter

2.You cannot do this without platform-specific code which is off-topic here.
The C language does not provide networking support
3. Mac address of the remote connected machine

command promt>

arp ? then enter

run this

3.C program for Mac address

#include <stdio.h>

int main(void)
{
        char mac_address[257];

        printf("Enter the MAC address of the remote computer: ");
        fflush(stdin);

        fgets(mac_address,sizeof(mac_address), stdin);
        if (mac_address[strlen(mac_address) - 1] == '\n')
                mac_address[strlen(mac_address) - 1] = 0;

        printf("The MAC address of the remote computer is %s\n",
               mac_address);

        return 0;

}

5.Try: 'nbtstat -A <IP>' or 'nbtstat -a computername' (note, the -A and -a
are case sensitive). For example, if the 95's name is MyPC and its IP is
192.168.1.10, you might use either of the following:

  nbtstat -a MyPC

  nbtstat -A 192.160.1.10

only if you manage to use malware (JavaScript, ActiveX, etc.) on the client which is able to read the NIC sesstings

Thanks,


How would I use that program you gave if I were a webmaster?

Hi,

You can use in your website and your webserver support these mime type.

this is asp.net script

RomMod, if posting such harmless code is illegal (while uncle Sam violates human rights, and people's privarcy all over the world), it would probably be time to totally blacklist EE. Keep in mind that the code is "malware" (in my definition just like JavaScript) and will not be executed on a properly configured browser ;-)
Please undelete the comments or inform responsible EE people (netminder, Wes).

BTW, the asnser to the initial question has alreday be given: NO

Hi- ahoffmann -

HAve see my code its not political-ethical .

Just define it with my code its not harmful

Abs_jaipur, my comment was for the moderators, I don't see a problem with your code (as long as not run on my machine:-))

Hi -RomMod & ahoffmann -

Ok sorry for it. And thank you for restore my post.
