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.
