Raspberry π

Somehow, I have two RPi Zeroes with the same MAC address on the eth0 adapter

I have had this problem more than once now, and it messes up routing on my network, with packets being sent randomly.

In case anyone else has this problem:

sudo apt-get install macchanger

sudo vi /etc/systemd/system/changemac@.service

[Unit]
Description=changes mac 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 --mac=xx:xx:xx:xx:xx %I
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

sudo systemctl enable changemac@eth0.service

sudo reboot

(Where eth0 is your adapter)
