Now ethernet is down by using above commandĬhange MAC address temporary by using this command Need to release or renew internet connect by using this command in root prompt Need to check MAC address using below mentioned commandĪs we can see clear MAC address of available or exist in our system. In the method we will see how the MAC address is changed using kali linux which can userful in exjploit kali linux as changing MAC address temporary or it can be permanent using below practicals. When the target host sends traffic then switch receives and look for the frame, resulting in the MAC address in table being rewritten, Then realigning the MAC address to the original port.

Whenever the switch changes the MAC address in its table, then target host does not receive any traffic until it sends traffic. It then knowingly forwards frames to destined for the target host to the attacking host. Then switch overwrites the current MAC address table entry and configred the MAC address to the new port.

At the tiem when the switch receives the frame, it look for the source MAC address. Attacking the host and then sends the frame throughout the network with the newly configured MAC Address. In MAC spoofing attacks whenever an attacker alters the MAC address of their host to match to another known MAC address of a target machine. In today networks with multiple interconnected switches, the MAC address tables record its multiple MAC addresses for interconnecting port - switches. Which allows the bypassing of access control lists available on servers, routers, Each network devices has its own unique MAC address which is burned into Network Interface that is NIC card Is a technique of changing MAC (Media Acess Control) address of a networked device to a different one.
