Get host MAC via REST API inside container

[Armin@netPI]

Well I would do it differently.

You need to know that the MAC address of a Raspberry Pi is starting always with B8:27:EB which is the vendor ID of the Raspberry Pi organization followed by the 6 last digits (3 bytes) of the serial number of Raspberry Pi CPU. This adds to 6 bytes

So with this knowledge you could easily build the MAC address your own without reading it across the web-UI.

This code below should help you to extract the CPU's serial number which should also work in a container I guess

Code:

cat /proc/cpuinfo |grep Serial|cut -d' ' -f2

Thx
