eth0 changes to eth2, Pi Zero's change address to 172.x.x.x

[Mark Strickland Emery]

Hi,

I have a working ClusterHAT setup that out of the blue changes eth0 to eth2, all Pi Zero switch from bridged DHCP addresses in my 10.0.0.0/23 LAN to 172 addresses that only the host can reach.

Anyone else seeing this? It last happened for me a couple of months ago, did it again this morning.

Thanks,

Mark

When you say eth0 changes to eth2 does it change whilst the Pi is running or does it change following a reboot or power off/on?

What do the logs show when it changes?

Which image are you running on the controller (If you don't know "cat /etc/os-release" should show the Debian version) and have you installed any additional software / made any config changes?

Which model of Pi are you using as the controller?

Is there much difference between "ip a" before/after it goes wrong?

Chris.
