This should be a lot cleaner solution.
However, two queries ::


a)
Doing "ifconfig" on the XO-1, only shows information for "eth0" and "lo"
(no mesh device listed).
So, how can the mac address for the mesh device be found?


b)
Are mac address for XO-1s, EXACTLY same, for every XO-1 on this planet?


Looking forward to a reply.



Thanks and Regards,
Ajay
