Change 'Cloned MAC address' in 'Network Connections' from command line?? SOLVED

[linx255]

Linux Mint 18 Sarah, 4.15.0-34-generic

I've tried changing my MAC address using macchanger and ifconfig methods but neither of these will reflect changes on my eth0 connection in Network Connections.

Here are the exact commands I used which failed ( used actual addresses and not X's ), which I got from a link on another Mint forum post:

Code: Select all

sudo macchanger -m XX:XX:XX:XX:XX:XX eth0

Code: Select all

sudo ifconfig eth0 down
sudo ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX
sudo ifconfig eth0 up

What is the proper command line method for changing the 'Cloned MAC address' so that the Network Connections connection will reflect the changes?

Or if this is something I can read up on myself please point to a resource; I'm having trouble locating information pertaining to how the connections in Network Connections are stored and changed in the file system. Or if I'm in over my head and I don't know what I'm talking about what should be my starting point?

Thank you.

Connections are on Mint (by default) managed by NetworkManager; you can use its command line tool nmcli for your purpose. Identify your connection name (or UUID) from the output of nmcli connection show and use

Code: Select all

$ nmcli connection down "The connection name"
$ nmcli connection modify "The connection name" ethernet.cloned-mac-address XX:XX:XX:XX:XX:XX
$ nmcli connection up "The connection name"

C.f. man nm-settings together with man nmcli for information on what's available.
