Randomization during Wi-Fi scanning is enabled by default starting on version 1.2.0, and it can be disabled by adding the following lines to /etc/NetworkManager/NetworkManager.Any hardware with a communications network interface card (NIC) will have been assigned by the manufacturer of the card a unique Media Access Control (MAC) address embedded on the network card, this address includes the manufacturer identification number, the make and model of the device could be embedded too. Both modes can be configured by modifying /etc/NetworkManager/nf There is some useful information about MAC address randomization during Wi-Fi scanning on the ArchWiki:Īs of version 1.4.0, NetworkManager supports two types MAC Address Randomization: randomization during scanning, and stable randomization. To disable this, you may edit your /etc/NetworkManager/nf as follows: NetworkManager will reset your MAC address during Wi-Fi scanning. To permanently change your MAC address, append the following line to your /etc/network/interfaces: pre-up ifconfig hw ether xx:xx:xx:yy:yy:yy But at the end of the day, they are also only wrappers for executing ip link set and macchanger.
You could also do it using systemd units as explained here: Changing mac using systemd units.
Udev method - Create the file etc/udev/rules.d/les with the following content: ACTION="add", SUBSYSTEM="net", ATTR="XX:XX:XX:XX:XX:XX", RUN+="/usr/bin/ip link set dev %k address YY:YY:YY:YY:YY:YY" However, if you are having problemas while changing mac through network/interfaces you could do it through udev Related stuff: Good detailed explanation of /etc/network/interfaces syntax? Example: auto enp3s0Ī detail that i have missed: The hwaddress configuration item needs to be after the gateway stanza, if you are setting a static ip address. Use the hwaddress ether inside your interface configuration block. I have been looking at tutorials online though I can't seem to get stuff right, and my computer even started acting very strangely a few times afterwards. I would like to change the mac address of all of my interfaces (enp3s0, wlp2s0) (lo is loopback so no need there), but I am unfamiliar with the commands in the /etc/network/interfaces file. I get the following output # interfaces(5) file used by ifup(8) and ifdown(8)Īnd when I do ifconfig on my ubuntu, I get back 3 different interfaces: Now when I use the following code: cat /etc/network/interfaces Stanza, e.g., right after the gateway line) so that the MAC address is On Debian, Ubuntu, and similar systems, place the following in theĪppropriate section of /etc/network/interfaces (within an iface
CHANGE NETWORK MAC ADDRESS REGEDIT HOW TO
So I found this great article online explaining how to change a Mac Address permanently through the /etc/network/interfaces file on my Ubuntu.
CHANGE NETWORK MAC ADDRESS REGEDIT CODE
How might I be able to specifically change the Mac Address of the enp3s0 and wlp2s0 interfaces through the /etc/network/interfaces file? What code would I have to include inside? I have been trying for some time now without success sadly enough.
