No eth0 device required to activate Matlab software

So, MathWorks requires a local Host-ID in order to use their Matlab software. According to their docs this is how you find the Host-ID, but such steps did not work for me.

https://www.mathworks.com/support/activ … ogethostid

Also, when I attempt to start Matlab with a license file using what I thought to be the correct Host-ID I just get this error:

License checkout failed.
License Manager Error -9
The hostid of your computer (000000000000) does not match the hostid of the license file
(0024be323423).

Troubleshoot this issue by visiting: 
http://www.mathworks.com/support/lme/R2012a/9

Diagnostic Information:
Feature: SR_MATLAB 
License path: /home/branden/.matlab/R2012a_licenses:/home/branden/Programs/matlab/licenses/license.dat:/home/brand
en/Programs/matlab/licenses/license.lic 
Licensing error: -9,57.

Which says my Host-ID is all zeros?

If I attempt and use the Matlab Installer's automatic activation it will fail for this very reason (Host-ID being found as 000000000000).

Error -2,007: Unable to activate your machine. The activation process cannot detect a
valid Host ID which utilizes a currently supported naming convention. Please refer to the
following solution ID, to help resolve this issue: 1-661QJD

I think this problem has to do with not actually having any "eth0" that is expected by matlab according to:
http://www.mathworks.com/matlabcentral/ … th0-device

For instance:

[branden@localhost net]$ ls /sys/class/net/
enp8s0  lo  wlp6s0

This is what you seek if you want an eth0: https://wiki.archlinux.org/index.php/Ne … Interfaces

Or crack open the thing that generates the Host ID (assuming it's not compiled) and replace eth0 with (probably) enp0s23 or whatever you NIC name is.

Re: No eth0 device required to activate Matlab software

moved to "Applications & Desktop environments"

Please add "Matlab" to the subject (e.g. "... activate Matlab software").

I saw that in my research but was worried that actually changing the name of the device would cause other cascading issues. Will this be the case?

Also, being quite new to Arch Linux, I do not have anything in /etc/udev/rules.d/
Do I just create the file 10-network.rules from the link you posted?

This solution worked perfectly.
