With Ubuntu 14.04 when I wanted to connect to a network using a different mac address I would run the following commands
sudo service network-manager stop sudo ifconfig $interface down sudo macchanger -m <mac_addresse> $interface sudo ifconfig $interface up sudo service network-manager start
This would assign a new mac address which persisted after network-manager was restarted and a new connection to the network was made.
now, on Ubuntu 16.04, after running those same commands using
sudo macchanger -m 00:60:1B:EB:F8:73 wlp2s0
I then restart
network-manager but not connected to the network yet, the new macchanger assigned mac address persists i.e.
% nmcli dev show wlp2s0 GENERAL.DEVICE: wlp2s0 GENERAL.TYPE: wifi GENERAL.HWADDR: 00:60:1B:EB:F8:73 address assigned by macchanger -->^^^^^^^^^^^^^^^^^ GENERAL.MTU: 0 GENERAL.STATE: 30 (disconnected) GENERAL.CONNECTION: -- GENERAL.CON-PATH: --
but the moment I connect to a network, the mac address is reset back to the original hardware mac address. after making connection to the network
% nmcli dev show wlp2s0 GENERAL.DEVICE: wlp2s0 GENERAL.TYPE: wifi GENERAL.HWADDR: E0:06:E6:A3:2C:A7 mac is back to original hardware -->^^^^^^^^^^^^^^^^^ GENERAL.MTU: 1500 GENERAL.STATE: 100 (connected) GENERAL.CONNECTION: lowfi GENERAL.CON-PATH: /org/freedesktop/NetworkManager/ActiveConnection/0 IP4.ADDRESS: 22.214.171.124/20 IP4.GATEWAY: 126.96.36.199 IP4.ROUTE: dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000 IP4.DNS: 188.8.131.52 IP4.DNS: 184.108.40.206 IP6.GATEWAY:
How can I make the macchanger assigned mac address persist when connecting to the network using the command line?
