Just like the previous method, this command only prints out the MAC address. If you want to see the address for a wireless device (wlan0), type this in the terminal instead: cat /sys/class/net/wlan0/address The address file contains the MAC address, and it is located in the /sys/class/net/ directory.Ĭonsequently, if you want to access the wired device’s MAC address (eth0) and see what’s inside, you’ll need to implement the cat command in the terminal: cat /sys/class/net/eth0/address Once you’re finished looking it over, you can exit by pressing the ‘q’ key. Note: If you want to learn more about ethtools and the many options it possesses, you can open its manual in the terminal by typing: The -P option is short for “show permanent address”. However, if you want to see the MAC address of wireless device (wlan0), you’ll just have to slightly modify it in your terminal: ethtool -P wlan0 It prints out the MAC address for the wired device (eth0) as soon as you type the following command in your terminal: ethtool -P eth0 It’s used for finding out information about connected Ethernet devices on your Linux system as well as for configuring them. Use EthtoolsĮthtools is a networking tool on Linux originally authored by David S. How To Find MAC Address On Raspberry Pi 1. For instance, you may want to change your MAC address each time you restart your system. Of course, if you want to avoid targeted ads from these companies, then the best way to prevent that is by creating a new MAC address regularly. MAC addresses have been known to be used by government agencies and some marketing companies to track computers over different networks. It’s mainly used to track a device over the network and is a protected way to find receivers and senders on the network. What Is A MAC Address?Ī MAC (Media Access Control) address consists of 12 characters that are either numbers or letters and are separated by either colons or hyphens. To help you better understand all these techniques better, I’ll explain each one in full for the rest of the guide. Lastly, you can edit the cmdline.txt file. You can also temporarily change it to an address you desire with the ifconfig and ip commands. You can download the MacChanger software and run it to generate random MAC addresses every time you connect to the Internet. There are 3 different ways you can change the MAC address. Now that you’ve located the MAC address, you might now be wondering “ How do you change the MAC address?“ You could also download and run a Python script or just boot up your Raspberry Pi without the SD card. If you want other information besides the MAC (like IP address), then you should use the ifconfig or ip commands. You can run the ethtools command or look in the address file for a quick and short answer.
The first thought you may have is: “How do you find a MAC address?”
