Date: Thu, 9 Jul 2015 14:16:06 -0400 (EDT)

Hello, I am trying to install guixsd with the installation image, my wireless
internet provider allows me for only one MAC. The command I use to change the
card mac on other distros and installation images is:

ifconfig device hw ether NewMacAdress

But with guixsd ifconfig fails telling me that the device can have only one
address. Interesting to notice that I can put whatever device, even non existent
names like "jlakjdj" and it tells the same thing, the device can only have on
adress. I have an Atheros card.

As I answered on IRC <https://gnunet.org/bot/log/guix/2015-07-09#T695806>,
my speculative guess is that perhaps ifconfig is patched on other
distros to handle this problem.

Did you try "ip link set <device> address <address>"?

That command is not in the installation image.

I think most other distros use ‘ifconfig’ from net-tools, not from
GNU inetutils.  If think this is just unimplemented.

Can someone at bug-inetutils comment?

This is in the ‘iproute2’ package.  Should we add it to the installation
image?

Thanks,

That  is  correct, GNU  ifconfig  does  not  support setting  the  MAC
address.

Guix also includes the 'iproute2' package, which includes a program
called 'ip' that can do the same kinds of jobs as 'ifconfig'.  I've
successfully used it in the past to set the MAC address of my network
devices.  IIRC, the command would be something like this:

ip link set <device> address <mac-addr>
