MAC-Sniffer

https://youtu.be/tu_N1xqSLxA

In this video we are going to build a tool that I am going to call the MAC Sniffer.
If your first thought is “the what now?”, don’t worry. This is probably the most niche tool/solution that you are going to see today. 🙂

Not a lot of people have this need, but recently I had to make a solution for an extremely niche problem.

You should watch the video because it explains the motivation behind the project, how it works and how you can build your own.

The TL;DR version is; This is a custom, stand-alone tool that reads device’s network MAC address and displays it on the screen as text and QR code. And it can also work with devices that don’t even have an OS installed.

You can find all the source files at MAC-Sniffer GitHub repository.

If you find this video/project useful, I would really love to hear from you.

    Hello friend,

    First of all, congratulations! Fantastic design, description, and housing.
    Thanks a million for sharing this.

    I have a question for you: would it be possible to add a “hostname” to expand the amount of information it retrieves?

    Best regards,

      Thanks! I’m glad you like it.
      If `hostname` portion is being transmitted during “handshaking” (which I believe it is) you should be able to modify the code to extract it.
