Sometimes it makes sense to connect to the PI Zero by using the g_ether kernel module. This connection is way more reliable than the WiFi connection in certain environments.
The setup is quite simple. dnsmasq will provide a local DHCP and DNS server.
- echo “dtoverlay=dwc2” | sudo tee -a /boot/config.txt
sudo apt install dnsmasq
/etc/network/interfacesand add the following:
auto usb0 iface usb0 inet static address 192.168.44.1/24
You can also disable the wlan0 interface by removing all the lines which mention it to disable wlan.
Edit /etc/dnsmasq.conf and add the following:
sudo systemctl enable --now dnsmasq
After a reboot of the PI you should see that the Ethernet Gadget on the connected USB host.
If you have trouble connecting it check the following:
- Did you use the correct USB port on the PI Zero? Only one offers the possibility to transfer data.
- Try to reload the kernel module:
sudo modprobe -r g_ether && sudo modprobe g_ether
- Is a firewall on the PI blocking the DHCP client?
