Update-: with 1.6 release and newer, the default value changed from “permanent” to “preserve”. In case no global override exists, NetworkManager falls back to “permanent”, like it did before.

“random”: generate a randomized value upon each connect.“preserve”: don’t change the MAC address of the device upon activation.Before 1.4.0, the permanent MAC address was used if the “cloned-mac-address” property was left empty, thus it was the default. “permanent”: use the permanent MAC address of the device.An explict MAC address: this was already supported before 1.4.0 and allows to spoof a specific MAC address.They got extended in 1.4.0 and support the following values: These settings take effect when activating the connection. Since long, NetworkManager supports two connection properties “ethernet.cloned-mac-address” and “wifi.cloned-mac-address”. A “connection” in NetworkManager-speak is a profile, a bunch of settings. Note that this is a per-device configuration value, because at the time of Wi-Fi scanning, no connection is yet activated.

This default behavior can be disabled with a global configuration option in nf: This was already enabled by default in 1.2.0, but as said, users likely didn’t have the required support from wpa_supplicant. Randomization during Wi-Fi scanningĭuring Wi-Fi scanning, NetworkManager resets the MAC address frequently to a randomly generated address. They support flexible mechanisms to generate a random address, most of these options are now also supported by NetworkManager. Tools like macchanger and macchiato are commonly used to change the MAC address of a device. Also, the same options are now available not only for Wi-Fi, but also Ethernet devices. This allows also for more flexibility to generate “stable” addresses and the “generate-mac-address-mask”. With NetworkManager 1.4.0, changing of the MAC address is done by NetworkManager itself, requiring no support from the supplicant. Such a release does not yet exist to this date and thus virtually nobody is using this feature. The problem is that it requires API which will only be part of the next major release 2.6 of the supplicant. The Tails distribution and Wikipedia have good reads on the subject.ġ.2.0 relies on support from wpa_supplicant to configure a random MAC address. Only be aware that for real™ privacy, more considerations come into play.

Suffice to say, some consider randomizing the MAC address an important feature to protect their privacy. He also explains why you may want to do that in the first place, so I skip the introduction. Previously NetworkManager 1.2.0 added MAC address randomization for Wi-Fi, as Lubomir explains in his blog post. Václav sleeps better with NetworkManager’s MAC address randomization This is also called MAC address “spoofing” or “cloning”. 0 adds new features to change the current MAC address of your Ethernet or Wi-Fi card.
