I just assembled a new 4-node cluster using 4 Pi Zero nodes on a Pi 3B+ master node.
I have tried configuring it with the NAT full and NAT std images. Both boot fine and I can start the 4 Pi Zero nodes and power them off en mass or singly just fine.
However, none of them produce any means of access. lsusb -t produces a list ending with the hub - no ports under the hub. And ifconfig -a does not reveal any net ports for any of the Pi Zero nodes.
Can someone enlighten me as to what I am missing?
thanks much for your time.
