Re: [STDS-802-Privacy] Random MAC addresses on Linux
Hi Juan Carlos, all,
I'm doing some testing with macchanger and network-manager in Debian,
based on [1].
I've found that the tool does not seem to allow keeping the vendor part
of the MAC address and randomize the last 24 bits, so I'd probably
implement a small script that does that and then I'll try perform
additional testing.
I hope I'll be able to provide more details on the experiments' outcome
soon.
Thanks,
Carlos
