Possible to Get the MAC Address?

Hardware Arduino Yún
#1

Is there any way to read the MAC address of the Wifi or Ethernet interface into an Arduino sketch?

If not, is there any other type of globally unique identifier that I can read from a sketch?

#2

Find all MAC address

/sbin/ifconfig -a | /bin/grep HWaddr

eth0      Link encap:Ethernet  HWaddr 90:A2:DA:F0:YY:XX
eth1      Link encap:Ethernet  HWaddr 90:A2:DA:F8:YY:XX
wlan0     Link encap:Ethernet  HWaddr 90:A2:DA:F0:YY:XX

Find WIFI MAC address

/sbin/ifconfig -a | /bin/grep HWaddr |/bin/grep wlan0

Find Ethernet MAC address

/sbin/ifconfig -a | /bin/grep HWaddr |/bin/grep eth1

Use Bridge you could read it from ATmega32u4 .

#3

find Wifi Mac Address only:

/sbin/ifconfig -a | /bin/grep HWaddr |/bin/grep wlan0 | /usr/bin/awk '{print $5}'

90:A2:DA:F0:XX:YY
