  Just for my info, what does this do that 'ip link set address xx:xx:xx:xx:xx:xx'
doesn't?

MACCHANGER_SITE = $(BR2_GNU_MIRROR)/macchanger

Hi Arnout; thanks for the feedback.

In addition to setting a specific MAC address, the tool can also be
used to set a random address. I don't think you can do that using ip.

Okay; will fix this and resubmit.

Simon.

Not with 'ip' only, but still possible:
  # MAC="$(dd if=/dev/urandom bs=6 count=1 2>/dev/null \
           |hexdump -e '5/1 "%0x:" "%0x"' )"
  # printf "%s\n" "${MAC}"
  b9:41:54:af:d9:f0
  # ip link set address "${MAC}"

UNIX-powa! And it's probably not the only possibility. ;-)

But yes, it's a bit more involved than simply calling a single executable.

Not much.

Besides setting MAC address to some specific value, it will let you to
autogenerate random
MAC address from within same device vendor, same physical device
category or completely random, bogust
MAC address.

So if you need to spoof MAC address when using aircrack-ng (which BTW, i
have as buildroot package here) or some
similar cracking tool then this might come handy.

But then again, and like you noted, there are already zillion of other
ways to change NIC MAC address ...

Best regards
