You are correct.  Inbound connections on eth1 were blocked and I had eth0
restricted to SSH/tcp while I was setting up the machine.  Normally I allow
all traffic from the local subnet.

Opening eth0 (or eth1) fixes the problem.  If I open both, then I need to
set EPICS_CA_AUTO_ADDR_LIST=NO and use EPICS_CA_ADDR_LIST.

I still don't understand why it didn't work from the local host.  iptables
accepts all traffic from the loopback.  Why doesn't that work for CA ?
