MATLAB: Activating on Linux without eth0

activationeth0

I have an activation question. I have asked technical support, but I thought I would ask here. I thought this would be desirable both in terms of speed for me and potentially to share the issue for others …
I run Arch Linux. Arch Linux has switched to the new standard of Consistent Network Device Naming where network devices are no longer named eth0, eth1, wlan0, wlan1. Both 1-661QJD and 1-EUTG50 are relevant and highlight the problem. For activation on Linux, TMW requires the legacy eth0 naming convention.
For Red Hat, TMW suggests removing the package that implements consistent network device naming. This is not an option on Arch. does anyone know a work around? Does anyone know a work around that does not require disabling consistent network device naming? I thought it used to be possible to activate with the UUID of a harddisk…

I asked a related question over at Unix and Linux.SE. Basically, for Linux the dummy kernel module will create a dummy network interface that you can then set the mac address of
modprobe dummy
ip l set dev dummy0 name eth0
ip link set dev eth0 address xx:xx:xx:xx:xx:xx
where xx:xx:xx:xx:xx:xx is the registered mac address/host id of the machine. I don't think that this violates the license agreement, although it is best to check.
I don't know the best way to make this persistent across reboots, but it shouldn't be too hard.
It might also be possible to simply rename one of the consistently named devices to eth0. This would eliminate the need for the dummy device and I believe the naming would still be consistent since you are always renaming the same device.
I have also been told that a udev rule can be used to revert back to ethX type naming. For machines that only have eth0 and/or wlan0 there is no advantage of consistent device naming since there is only one device. This means the udev rule does not hurt anything.
