We will use Kali Linux to demonstrate the steps from this article. In this tutorial, I will cover what we mean by MAC address, what it's used for, and how to change it. Now imagine you have 100s of servers, so connecting to each one and getting the MAC can be nasty so we can just change the MAC address of these servers as per our need and then just use them to perform PXE boot.ĪLSO READ: Use Burp Suite Proxy to Intercept Network Traffic Now this should not be a problem when we are using DHCP but if you want to use static IP then you must define the MAC Address of the interface and the IP to be assigned. For PXE boot we perform network based installation.So we decided to update the PCI ID of each interface using udev rule bundled inside initrd to overcome this issue. We had a very old rack server where we failed to installed RHEL 8 and the MAC address of the interfaces from this server kept changing after every reboot.Now you may wonder when the MAC Address is already assigned to an interface then why would we want to change it? Well there can be a number of scenarios, speaking from my personal experience MAC Address is a physical identity assigned to each interface. When it comes to networking, you've probably heard of the term MAC addressed a lot.
