First of all: Thank you very much for building and maintaining this package, it's very useful.

Today, I noticed what I assume to be a bug:

# Preparation
npm i -g spoof

# see the corresponding help message
spoof --help
# …
# spoof version | --version | -v          Show package version.
# …

# While these two lines work:
spoof version # (prints "2.0.1")
spoof --version # (prints "2.0.1")

# The following results in an error:
spoof -v

This bug is of course not too much of a problem when using the tool, it is only about retrieving the version number, after all, and there are other ways to obtain that information, but I thought I should report it here anyway.

This is mostly a placeholder issue till me or somebody else implements it.

I believe the correct commands are

netsh wlan disconnect
netsh wlan connect name="WIFI-NAME"

Problem:

After randomising MAC address with

sudo spoof randomize <device>

where the device is a wifi connection, the computer does not re-connect to the last connected wifi.

Proposed Solution

turn the wifi card off and on after randomizing MAC.

Just a suggestion to add support for randomize with a given prefix

I do no get any output from this tool when I run spoof list on Linux OS.

I've narrowed down the condition it is failing to pass, it is the regular expression for parsing the output of ifconfig.

Do we know why the pattern of (.*?)HWaddr(.*) is expected? Can we improve this parsing?

Encountering this issue with a 2018 MacBook Air on macOS Mojave 10.14.6.

Running the following command fails without any status messages:

sudo spoof set aa:bb:cc:dd:ee:ff en0

I run the command, enter my password, and the command seems to complete. However, running spoof list reveals the Mac Address has not changed.

This issue appears to affect manually setting the address with ifconfig as well. Running this command also does not change anything and does not throw an error:

sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

Not sure if or how Mac spoofing might be disabled system-wide, or if something else is going on here. Any help is appreciated.

Hi,

Ifconfig command is deprecated. Please support ip command. which is supporting on spoofMac project.

Thank you

Wasn't able to play with this due to its reliance on ifconfig, where I use iproute2.
The equivalent commands to randomize your MAC using iproute2:

ip link set dev eth0 down
ip link set dev eth0 address `hexdump -n3 -e'/3 "00:60:2F" 3/1 ":%02X"' /dev/urandom`
ip link set dev eth0 up

Up to you if this information is useful or not, just putting it out there for others.

Hello!

This is a great tool but something that would make it even better is the ability to randomise after X MB is sent and/or received from the server.

Hello! I'm not sure if this is the right place to do this but i recently stumbled upon this error a little bit ago on windows 11 even tho this command was working perfectly before. Running spoof list returned devices without a name but with a MAC address and i couldnt do anything to randomize my adapter. I just figured out how to fix it so i thought i'd save you guys the time and effort

1. Simply open your settings, go to Network & Internet > Advanced Network Settings

2. Under Network Adapters, find your Wifi Adapter. For me it was the second one.

3. Click the Dropdown and under "Rename this adapter", rename it to something like wi-fi

4. Restart your command line and then run spoof list. You should see Wi-Fi come back

5. Run spoof randomize Wi-Fi or whatever the device name is under that command

I hope this is helpful to anyone. I know nothing about node js so i cant really help much, i kind of just aimlessly stumbled upon a solution after two days. Thank you feross for creating this amazing command, it's saved me a bunch :)

Q: Is it possible to use this repository as the default brew formulae?

Rather than the default python brew option.

Hello, not sure if this is a bug or something wrong with my system but I thought I'd report it anyways, perhaps someone could look into it.

The output below, notice lines such as "- on device Wifi with MAC address B8:EE:65:98:0C:4F " immediately after the - in the beginning of the line, there should be the name of the device. Without said line I am not able to properly select the adapter I want to change MAC for.

Hi Feross,

I have a quick question. I plan to package this software (or SpoofMac) for Debian. Which of these two (this nodejs version or the python version) is more stable and maintained? Is your intention to replace the python version with this nodejs version? Or is the nodejs version experimental?

Cheers,
Kevin

Hello! I can try again and paste output if necessary, but I got

Error: Object # has no method 'execSync'

when doing "spoof list" using nodes 0.11.11.

Thanks!

Hi, I'm running Elementary OS and using your script via Node.

I uses another script to change my MAC address that also edits it in /etc/NetworkManager/System-Connections/MYNETWORKNAME

I ran your script and it did not change it in that file. When I logged in to my router, the old MAC is still listed for my connection but running ifconfig lists the MAC your utility gave me. Sorta odd.
I'm actually surprised it connected to the network in the first place.

Any ideas what might be happening?

What are root privileges in the context of a Windows OS? Do you mean Admin privileges?

Hi, I was using this for a while now then all of a sudden it won't change the MAC address.
It says it has but it has not changed anything.

I'm using latest version and on macOS 1.13.6

Unable to Spoof on Macos Sonoma 14.4.1
I was Using spoof-mac for a couple years and last week it start throwing this new issue

then i installed this but it also isn't working

$ sudo spoof set XX:XX:XX:XX:XX:X9 en1
$ spoof list

• Ethernet on device en0 with MAC address XX:XX:XX:XX:XX:XX
• FireWire on device fw0 with MAC address XX:XX:XX:XX:XX:XX
• Wi-Fi on device en1 with MAC address XX:XX:XX:XX:XX:X8 currently set to XX:XX:XX:XX:XX:X9
• Bluetooth PAN on device en2 with MAC address XX:XX:XX:XX:XX:X8
  $ sudo spoof set XX:XX:XX:XX:XX:XX en2
  ifconfig: interface en2 does not exist
  Error: Unable to change MAC address

Have you ever (or anybody else) been able to spoof a Bluetooth PAN MAC address in any way?
Seems to me that it cannot be done with ifconfig since ifconfig command does not ever show that interface on my system, as opposed to networksetup -listallhardwareports which does

Any attempt to set a MAC address results in:

ifconfig: ioctl (SIOCAIFADDR): Operation not supported on socket

spoof actually supports windows since April 2016 but we still haven't updated the readme.

This issue is mostly a placeholder if and when somebody finds the time for it.

It works like charm on macOS Catalina. But not Big Sur.

I think you should be using the newer ip command as ifconfig is not only deprecated, but also inconsistent across linux distros.

I'll make the necessary changes if you're willing to accept the move from ipconfig to ip.

It seems all 2018 version macbook pros are unable to change mac address using "ifconfig ether".
