Fix the MAC address of RoadRunner
Unfortunately RoadRunner doesn't have a its own unique hardware MAC address on port eth0 so you have to provide
in a software manner. This article explains how to set the MAC address using maccharger utility
GNU MAC Changer is an utility that makes the maniputation of MAC
addresses of network interfaces easier.
Install maccharger o Raspbian distribution:
sudo apt update
sudo apt install macchanger
Select No to "Change MAC automatically?" answer during the installation.
Create a systemd file called setmac@eth0.service
sudo nano /lib/systemd/system/setmac@eth0.service
insert on it this content using the MAC address you need to set on the eth0 interface
(use https://miniwebtool.com/mac-address-generator/ to generate a random MAC address):
[Unit]
Description=Set the MAC address for %I
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%I.device
After=sys-subsystem-net-devices-%I.device
[Service]
Type=oneshot
ExecStart=/usr/bin/macchanger -m b2:aa:0e:56:ed:f7 %I
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
Enable the systemd service at startup:
sudo systemctl daemon-reload
sudo systemctl enable setmac@eth0.service
then reboot:
sudo reboot
