I have Clusterhat v2.5, was working great until a reboot.
Now, p1.local, p2,local, p3.local, p4.local don't resolve.
I can ping p1, p2, p3, p4 and get responses and see their ip addresses.
If I try to ssh into one of the zeros (say 'ssh p1'), I get prompted for a password and it appears like it logged in but I am back at the pi@cnat prompt of the controller and if I do ifconfig I see it is the controllers ip address, not the zeros.
Any ideas?
