Changing MAC Address on PiKVM

  1. Connect with PiKVM via serial connection. While using a minicom

there is a need to use the USB-UART converter.

Open the serial connection by executing the following command:

```bash
sudo minicom -D /dev/ttyUSB0 -b 115200
```
  1. Check the current MAC address of the network interface:
ip a

Note the exact interface name for later use.

  1. Remount the filesystem in read-write mode:
sudo rw
  1. Navigate to the network configuration files:
cd /etc/systemd/network
  1. Open the file corresponding to desired network interface using nano or vim:
sudo nano wlan0.network
  1. Add following lines to the file. Replace xx:xx:xx:xx:xx:xx with desired MAC address:
[Link]
MACAddress=xx:xx:xx:xx:xx:xx

Save the file and exit the editor.

  1. Restart the systemd-networkd service:
sudo systemctl restart systemd-networkd
  1. Remount the filesystem in read-only mode:
sudo ro
  1. Reboot the system:
sudo reboot now
  1. Verify the new MAC address for your interface:
ip a
