Awesome blog.
If you could indent your code it would be much more readable.

System.out.println on a byte[] won’t give you useful output…

not run in divices with more than one ethernet driver. sample: ethernet0 local address and wireless network.
El codigo no funciona en equipos con mas de un driver de red. O sea, si el dispositivo tiene red inalambrica y red lan, si alguno de ellos no esta coenctado no funcionara en la mayoria de los casos, para eso se debe buscar cual de ellos es el que necesita y obtener la direccion mac de ahi… suerte…
