Hi! Thanks for you reply. On 09.11.2016 13:31, John W.

You could do this on the RPi, but after that you haven't no more network connection. It's like Hans Petter said: The sys/dev/usb/net/if_smsc.c driver needs a patch to set the mac address runtime. I don't know, how to write it, because I am not really familiar with C source code. > https://en.wikibooks.org/wiki/Changing_Your_MAC_Address/Linux, which also > specifically addresses how to make > persistent. In all flavour of Linux that should work, without problems on the RPi. You could set the MAC address from the kernel command line. > In addition I noticed that the MAC address, which you are trying to use > instead of the burned-in one, contains 'FF', which, given its use in > functional MAC addresses used for broadcast type purposes, might not be such > a good idea. Really, that I don't know. I only use it, as an example, instead of 00:11:22:33:44:55. Overriding the burned-in MAC address persistent on a RPi wouldn't work, because it is generated from a combination of the MAC range (b8:27:eb) and the last three bytes of the serial number. But it should be possible to change this in this RPi FTD file, then it might work. Best regards,
