I have two machines on a home network:

On cyrus : ping saturn and host saturn both fail saying saturn can't be

On saturn: ping cyrus works but host cyrus fails.
ssh cyrus, works

I don't use iptables. Any explanations for this behavior?

Errors are like:
** server can't find saturn: NXDOMAIN

I suspect that some things use the local /etc/host bu others do not.

Certainly the 'host' command doesn't use /etc/hosts so that suggests:-

cyrus can't find saturn using DNS but saturn is in its /etc/hosts
file so ssh works.

saturn can find cyrus using DNS, it may well be able to find it
using /etc/hosts as well.

I wonder if you have things set up so ping (ICMP packets?) are refused
somewhere in the system so that ping will never work regardless of
DNS, routing, etc.
