Solving MAC address duplicate with Macchanger

[noibla74]

To solve the same MAC address on nodes a possible solution is to:

install macchanger

Apt install macchanger

Create Bash script
for example vi setmac.sh with content
#!/bin/bash
ifconfig eth0 down
macchanger --mac=<mac address seperated by colon> eth0
ifconfig eth0 up

Make Bash script executable
chmod +x setmac.sh

Run Bash script
sudo setmac.sh

Note , the script helps to change the MAC address while the interface is not in use

I did try macchanger with sinovoip provided armbian image few months ago.

Since bpi-cm4 official support on armbian I didn't encounter this issue again after writing distro on emmc.

I guess my testing array is a bit outdated now.
