matlab on WSL2 Licensing error: -9,57.

Hello,

I have matlab R2021b installed on my wsl ubuntu 22.04 on windows 11. Everytime I turn on my PC and try to run matlab from the wsl ubuntu terminal, I get a licensing error. I looked online and people suggest this is due to the wsl having a dynamic mac address that changes every startup. I can resolve the issue by going through activation again using the command /usr/local/MATLAB/R2021b/bin/activate_matlab.sh. But the solution is temporary, I have to redo this everytime I turn my pc off and on.

Is there a more permenant solution available?

Thank you!

See https://github.com/microsoft/WSL/issues/5352#issuecomment-699839455 for discussion of bond0

Thanks, I had to scroll through the many different solutions to find one.

The newer versions of WSL2 do not have bond0 so I had to first create using the cmd: ip link add name bond0 type bond mode active-backup

Then added some commands in my .bashrc that would set the MAC address of bond0 upon boot.
