Once and for all DISABLE MAC RANDOMIZATION

[Schorschi]

Once and for all DISABLE MAC RANDOMIZATION? The idea that a wired NIC should have a randomized MAC... Has to be one of the !!!!... So how do you explicitly disable ALL MAC RANDOMIZATION on wired NICs?

I have spent over 2 hours trying 5 or 6 methods, include macchanger... NOTHING IS WORKING with Debian 12. Using NetworkManger but I realize the randomization maybe coming from systemd? Or somewhere else? Have clients that use PCLAAs and MAC auditing... so RANDOMIZED MACS IS A HORRIBLE IDEA!

How do I DISABLE this horrible feature!???

Moving from "Installation" to "System and Network Configuration" sub-forum.

No idea, never seen the issue and thought it was only user configured?
Do you have randmac installed for some reason?

Hi @Schorschi can you just mention the methods you've tried so nobody repeats themselves?

Hello,

how do you explicitly disable ALL MAC RANDOMIZATION on wired NICs?

You can search the system logs to find out which system service is currently updating the MAC address of your NIC by using the following command:

Code: Select all

su -l -c "journalctl -g mac\ "

Please, use code tags to include commands and/or their logs in the body of a message.

Hope this helps.
