macchanger

[labbe5]

macchanger and macchanger-gtk (GUI) is in your standard repositories.

Setting is done while installing : have mac address changed automatically each time you plug in ethernet cable or change network? Your input : yes or no.

It’s also a good idea to turn off WiFi scanning if you’re not actively using it. You can be tracked via MAC address by leaving it on. Linux users can use macchanger to spoof their address, but Windows users are out of luck. Some mobile phones automatically change addresses, but not very effectively. Recent editions of Windows 10 give you the option to randomize your MAC address at new networks. Doing this will greatly help prevent tracking.

To use macchanger-gtk, open your terminal and type macchanger-gtk. A GUI is launched, and you can change your mac address as often as you want. Manually changing your mac address is good for a desktop computer using ethernet cable 24/7.

In my terminal, what i did :
johnny@ubuntu:~$ sudo -s
root@ubuntu:~# macchanger -r xxxxxxx
Current MAC: xx:xx:xx:xx:xx:xx (XYZ Communications, Inc.)
Permanent MAC: xx:xx:xx:xx:xx:xx (XYZ Communications, Inc.)
New MAC: 12:48:c4:04:dc:11 (unknown)
root@ubuntu:~# ifconfig xxxxxx up
root@ubuntu:~# service openvpn restart
root@ubuntu:~# macchanger -s xxxxxx
Current MAC: 12:48:c4:04:dc:11 (unknown)
Permanent MAC: xx:xx:xx:xx:xx:xx (XYZ Communications, Inc.)

I had to do openvpn restart to deal with a lost of connectivity to the internet.
ifconfig up was done because of a lost of connectivity after the changing of mac address, but i had to restart openvpn as a final step.

When possible use the GUI, it is simpler.

UPDATE
I came across this problem faced by a forum member :
Now problem is that video player only works on a single pc and not on other pc. I have to run these video file on my laptop but that application is not running on my laptop or any other pc.
Screen recording is one solution. But there is also clone mac address from one PC and use it on the other PC. You put macchanger to good use doing this.

A GUI for it

This is good for a laptop you take different places, but if you have cable internet at home then the mac address that everyone on the outside sees is the modem/router's mac address, not your computer's mac address.

At least for Charter/Spectrum if you use their modem/router, it is tied to your account and if you go into the modem/router software and manage to change it your router won't work anymore.

However, if you have your own modem/router, then you can spoof the MAC address (assuming your modem/router will let you) and give them the fake MAC address when you call them to provision the router. Then if you want to change it (or want to change your IP address because they are tied together), then give your modem a new fake address, and then call them and tell them that you bought a new modem/router and they will provision it again with the new mac number and you'll be automatically assigned a new ip number.

YMMV
