How to make "ether" value from "bond0" field static across WSL sessions

[ramees041]

Is your feature request related to a problem? Please describe.
I have an application which access the "ether" value from "bond0" field as input parameters to generate a license (Note:- Without this license application cant be opened).
This ether value is found to be dynamic across WSL restarts.
So, on every WSL restart, I will have to generate another new license to continue using it.

Describe the solution you'd like
I want "ether" value under "bond0" to be static across across WSL sessions.

Describe alternatives you've considered

This isn't materially very different from #5291 (with a side of #5352).

It does seem like changing the MAC of bond0 has no ill effects, on first glance anyway:

Is there a way automate it rather than typing it manually on every restart?

[therealkenc]

In .bashrc add a test to see if the MAC has been set to the value you want, and if not, set it. Add /usr/bin/ip to /etc/sudoers.

Will it affect accessing GUI apps, internet browsing or any other service?
Also I would like to know, if at all it affects anything, are there any irreversible affects?

It does not seem to, on the first and only first glance I did, anyway. Can't tell you it won't with any specificity. It appears to be state DOWN so there is no obvious reason why it should. Any ill effects it did have, should they arise, would be reversible.

Could you please elaborate more on how can I add /usr/bin/ip to /etc/sudoers?I am afraid I might do it wrong.

[therealkenc]

Sure. Something like this at the end of your /etc/sudoers. You can edit with sudo /etc/sudoers.

yourusername ALL=(ALL) NOPASSWD: /usr/bin/ip

In your .bashrc you can test and set with something like:

wantmac=00:15:5d:7d:e1:2b
mac=$(ip link show bond0 | awk '/ether/ {print $2}')
if [[ $mac !=  $wantmac ]]; then
    sudo ip link set dev bond0 address $wantmac
