- Create simple CentOS 7 Virtualbox with Packer As a software tester you need many virtual machines, the creating can be very time consuming. Of course tools like Vagrant helps a lot but the creation for BaseBoxes starts most with installation from ISO`s. Exact here helps Packer!
- Creating a VirtualBox Virtual Machine for CentOS 8: Open VirtualBox and click on New. Now, type in a name for the Virtual Machine (VM), select the Type to Linux and Version to Red Hat (64-bit). Then, click on Next. Now, you have to set how much Memory (RAM) you want to allocate to the VM. For headless servers, 1 GB or 1024 MB is enough.
This tutorial will show you how to change MAC Address in CentOS 7. I assure you this is a perfectly working and tested method. In many cases you need to change MAC to allow internet access or run any MAC based licensed software like Radius Manager. So for those situations here we go.
Steps to change MAC Address in CentOS 7:
- Update CentOS Repositories by:
- Install nano (for editing config files) and net-tools (for enabling ifconfig command).
- Go to the ethernet configuration file.
- Add the following line. Replace the current MAC with your desired MAC Address.
- Save the configuration file.
- Restart the networking process.
- You are done. Now, verify by issuing ifconfig command.
- If you have a windows machine in the same network. Issue arp -d to delete current ARP table. Then ping CentOS 7 IP Address from Windows PC. Next issue arp -a. You will find the changed MAC next to your CentOS 7 IP Address.
