Randomizing MAC address on startup in Linux Mint

I’d like Linux Mint to randomize my MAC address on startup on all network interfaces (enp2s0f1 & wlp3s0), and notify me if one of them failed to change via a pop-up.

How would I go about doing this?

(I’m running Linux Mint 18.1 64-bit)

are you using network manager/wicd/etc or do you connect via /etc/network/interfaces ?

A more standard way to randomize mac addresses is using macchanger.

Following (roughly) the instructions of the ubuntu wiki: AnonymizingNetworkMACAddresses

Install MACCHANGER

The package macchanger is in the Networking
(universe). Install it.
apt-get install macchanger 
Create the Randomizer Trigger

Utilizing Network-Manager's methods to trigger events when a network
interface changes state, place the macchanger script into
/etc/network/if-pre-up.d.
vi /etc/network/if-pre-up.d/macchanger   
Don't change $IFACE. It is a
reference provided by NetworkManager for the particular activated
interface.
#!/bin/sh



# Randomize the mac address for the given interface 

/usr/bin/macchanger -e "$IFACE" 
Make it executable.
chmod +x /etc/network/if-pre-up.d/macchanger 
Interface State Change

Now everytime any managed interface is activated, as it passes through
the pre-up phase, the network MAC address will be randomized under the
VENDOR id.

Fully Random

If you desire a completely random MAC address change the
-e in the macchanger script to -r.

I went to create the /etc/network/if-pre-up.d/macchanger file, but it tuns out it already existed, and had content in it (I have no idea why). Here is what it had:

That means when running network config from the terminal, macchanger # will be run twice, but it'll only be run in if-post-down.d when using # NetworkManager. (continues)
