Here we use Nmap SNMP script to query SNMP service simply. #Command to find mac address linux mac#SNMP tools can be used to get the mac address of the hosts. The more complicated way is using SNMP service. $ sudo nmap -sP -n 192.168.122.0/24 Get Mac Address Of Remote But Same Network System Get Mac Address Of Remote System With Snmp We can use Nmap to get mac address of a host if we are in the same network segment. $ ip link Get Mac Address Of Local System Get Mac Address Of Remote But Same Network System Getting local systems mac address is easy and have a lot of different ways. ![]() I can be used to get remote systems mac addresses but SNMP should be enabled on remote systems. ![]() The mac-related feature can be used to get mac addresses of the hosts in the same network segment. It is used by penetration testers mainly but from an operation perspective, it is used by system administrators too. Stay tuned with It’s FOSS for more Linux tutorial and tips.Nmap is a very useful tool. You have successfully changed the MAC address in true Linux style. In the output below, the MAC address is the hardware address (HWaddr), as highlighted below. After running 'ifconfig' from the command line, you get output similar to the example below. Now, verify new MAC address: ip link show enp0s31f6 If you are running Linux and Unix or a variant, you can determine the MAC address or hardware address using the ifconfig command. Next, set the new MAC using command: sudo ip link set dev enp0s31f6 address XX:XX:XX:XX:XX:XXįinally, turn the network back on with this command: sudo ip link set dev enp0s31f6 up It will probably look something like this: link/ether 00:1d:98:5a:d1:3a The first step to spoofing the MAC address is to bring the network. The section that interests us at the moment is the one that has 'link/ether' followed by a 6-byte number. where interface is the name of your network interface. I would recommend using Macchanger but if you don’t want to use it, there is another way to change the MAC address in Linux.įirst, turn off the network card using command: sudo ip link set dev enp0s31f6 down First, you can check your current MAC address with the command: ip link show interface. Method 2: Changing Mac address using iproute2 You can always check the man page for more details. Once you reboot the system, the changes will be automatically lost, and the actual MAC address will be restored again. Where XX:XX:XX:XX:XX:XX is the new MAC id that you want to change.įinally, to revert the MAC address to its original hardware value, run the following command: macchanger -p enp0s31f6 To change the MAC address to a specific value, specify any custom MAC address using command: macchanger -mac=XX:XX:XX:XX:XX:XX You will now see that MAC has been spoofed. Now, to assign any random MAC address to this network card, use: sudo macchanger -r enp0s31f6Īfter changing the MAC id, verify it using command: ip addr #Command to find mac address linux how to#How to Use Macchanger to change MAC addressĭo you remember your network interface name? You got it in the Step 1 earlier. So, choose No (by pressing tab key) and hit Enter key to continue. I recommend not to run it automatically, unless you really need to change your MAC address every time. This gives a new MAC address whenever you attach an Ethernet cable or re-enable WiFi. Important! You’ll be asked to specify whether macchanger should be set up to run automatically every time a network device is brought up or down. #Command to find mac address linux install#On Debian, Ubuntu, Linux Mint, Kali Linux: sudo apt install macchanger ![]() On Fedora, CentOS, RHEL: sudo dnf install macchanger ![]() On Arch Linux or Manjaro: sudo pacman -S macchanger It is available in almost all GNU/Linux operating systems and you can install is using the package installer of your distribution. Macchanger is simple utility to view, modify, and manipulate MAC addresses for your Network interface cards. Method 1: Change MAC address using Macchanger So either try this method on an additional card or be prepared to restart your network. If you do this on a network interface which is currently in use, probably your network connection will be terminated.
