How to obtain the client MAC address

Method 1:

Call the Windows doscommand to read the MAC address from the output:

Public static string getmacaddress (){

String address = "";
String OS = system. getproperty ("OS. Name ");
If (OS! = NULL & OS. startswith ("Windows ")){
Try {
String command = "cmd.exe/C ipconfig/all ";
PROCESS p = runtime.getruntime(cmd.exe C (command );
Bufferedreader BR =
New bufferedreader (
New inputstreamreader (P. getinputstream ()));
String line;
While (line = Br. Readline ())! = NULL ){
If (line. indexof ("physical address")> 0 ){
Int Index = line. indexof (":");
Index + = 2;
Address = line. substring (INDEX );
Break;
}
}
BR. Close ();
Return address. Trim ();
}
Catch (ioexception e ){}
}
Return address;
}

We can replace the "ipconfig" to "Ping x. x. x" and "ARP-a"... we can get the Mac list... haha !!

Disadvantage: only the MAC address of the server can be obtained. If you want to obtain the MAC address of the client, you need to use the applet. Only for the MS-WIN system.

 

Method 2:

You can use JS or VBScript to call the WMI interface to obtain the MAC address of the client.
