How to Manually Find and Change the MAC Address in Linux

#LINUX FIND MAC ADDRESS USING IP ADDRESS PASSWORD#

Another usage example would be cloning a MAC address of another device forcing it to disconnect from a network and to connect again, useful to sniff a password when the device reconnects.Īfter reading this article, you will know how to change your MAC address both manually and automatically, with a specific MAC address or with a random one.Īll steps described in this tutorial include screenshots, making it easy for any Linux user to follow them. This is useful, for example, to be able to connect routers or networks allowing specific MAC addresses, or to avoid leaving traces. Yet, while the MAC address is permanent from the hardware side, there are some workarounds to change it before the network or other devices. Contrary to the IP, the MAC is permanent and assigned from the factory.

#LINUX FIND MAC ADDRESS USING IP ADDRESS SOFTWARE#

While the IP is the software address, the MAC is the hardware or physical address. Like the IP address, the MAC address is unique for each device. Network cards have a minimum of two addresses to be identified, at least one IP address (You can assign more than one), and a physical address named MAC address. 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.This tutorial explains how to find and change the network card MAC address on Linux. 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).

#LINUX FIND MAC ADDRESS USING IP ADDRESS INSTALL#

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. Modifying your system's MAC address allows you to impersonate other devices on the same network.
