Spoofing your Mac address prevents direct hacking because the impersonator cannot access your device directly without the actual address. The danger occurs in schools, public Wi-Fi, and workplaces alike. Of course, you’d have to use only one of the two devices that use the same MAC address.įurthermore, hackers on the same network as your devices do exist, depending on circumstances. This process allows your spoofed device to gain benefits from the other device. If your ISP or local domain restricts a device’s bandwidth, app use, or priority based on the identified Mac address, changing it to another device’s Mac address fools the ISP.

Another term for this transition is Mac spoofing, which is done for legitimate and illicit purposes alike. Other times, you may want your device to appear as another one even though it is not. Restart the network interface using ip: sudo ip link set dev eth0 upĬheck if the aforementioned command worked by typing ip addr into the terminal.Sometimes, you may want your device to bypass access control lists on routers or servers to hide it from other networked devices and users. Then change the original MAC to a custom address as follows: sudo ip link set dev eth0 address 44 :ee :bc :6c :76 :ba You'll have to manually change the modified address to the original MAC.īefore you can change the MAC address of your device using ip, you'll have to shut down the network interface. Once you've changed the MAC address using the below-mentioned commands, there's no option to revert to the original address automatically. You can effortlessly reset the changes back to default using the -p flag: sudo macchanger -p eth0 Using ip and ifconfig CommandsĪlthough macchanger is easy to use and well-suited for beginners, advanced Linux users who want more control over the operation might prefer using the ip command.īut first, make sure you note down the original MAC address of the interface before modifying it. With macchanger, you don't have to memorize the original MAC address of your device for future reference. To assign a custom MAC address to the eth0 interface: sudo macchanger -m 44 :ee :bc :6c :76 :ba eth0 where custom-address is the new MAC address you want to assign and interface is the name of the network interface. Simply use the -m flag with the default command as follows: sudo macchanger -m custom-address interface In addition to assigning a random address, you can also set a custom MAC address for your device. Select No and press Enter to continue.īefore getting practical, first, you need to check the network interface names on your device. You will see a prompt asking whether you want to change your system's MAC address every time you restart a network device (including ethernet and Wi-Fi).

To install macchanger on Arch Linux: sudo pacman -S macchanger On Fedora, CentOS, or other RHEL-based distros: sudo dnf install macchanger To install it on Debian/Ubuntu: sudo apt install macchanger Macchanger is a terminal-based Linux utility that allows a user to change the default MAC address of their device. Here's how you can spoof your MAC address on Linux. Whatever the reason be, Linux tools have got you covered. Maybe you want to bypass security restrictions on a network, or maybe you wish to imitate another device on the network to capture packets. There are loads of reasons why you might want to change your device's MAC address. In the OSI model of networking, MAC addresses are responsible for sending data to the correct device in the Data Link layer. It is because of MAC addresses that you are able to uniquely identify millions of devices connected to the internet. Here's how a MAC address looks like: 55 :de :bc :7d :45 :dfĮach device is assigned a unique MAC address during its manufacture. It is also known as the "physical address" of a machine since it is embedded in the Network Interface Card (NIC) of the device.

But finding a reliable and stable utility that does the job well is really complicated considering the number of choices available to a user.īy the end, you will have a brief understanding of MAC addresses, and how to spoof your MAC address on Linux.Ī MAC address, or Media Access Control address, is a unique hexadecimal identifier used to identify a device on a network. On Linux, you can find countless tools to change your device's MAC address. This way, you can receive data packets that were originally meant for the other device.
