Getting the MAC of your Logic Machine.

[rocfusion]

Hi,

The following code will allow you retrieve the MAC address of your Logic Machine.  Whether this is useful, to some, anyway here it is

Thanks,

Roger

Code:

local f = io.popen('ifconfig')
local t = f:read()
f:close()
local mac = t:match("HWaddr ([%:%x]*)") 

alert(mac)

There's a faster way

Code:

mac = io.readfile('/sys/class/net/eth0/address'):trim()

Yep I knew that one, that works on the presence that 'eth0' always exists.

Ethernet is physically present on all devices. If you need some kind of identification, you can also get unique CPU ID by reading "/proc/device-tree/uniqid"
