I followed this guide to turn my Raspberry Pi Zeroes into ethernet gadgets and I did not change anything in the
/etc/dhcpcd.conf files. All of the SD cards were fresh installs of Raspbian Jessie Lite from March 2016.
I connected 3 of them to my Raspberry Pi 2 to experiment with a little cluster.
The issue is that when I have more than one Pi Zero connected to the Pi 2, I can communicate with only one of them at a time. If I ping each of them, only one will be reachable and that's the only one I can ssh into. If I reboot it through ssh the problem continues, but with another Pi Zero responding to a ping and accepting ssh connections.
I am not familiar with network configuration. How can I make all my Pi Zeroes visible to my Pi 2 at the same time?
EDIT: Each Raspberry Pi have a different hostname, I'm using
hostname.local to ping and ssh.
EDIT 2: When I ran
ip neighbor I saw that it is trying to reach all of the Pi Zeroes on the same interface, is there a way to select the correct interface for communication?
