First of all you should not be using anything as dangerously insecure
as the Berkeley r- protocols (rsh/rlogin/rexec). Use SSH. Secondly, if
you configure the DNS properly for these multi-homed hosts, everything
would just work. All you have to so is arrange that reverse lookups of
the multi-homed host's addresses all return the same name (as they
should do). Forward lookups of that name should return all the
addresses of the multi-homed host.
