So that's interesting since it is a clear failure that comes from the
operating system and indicates something which can be observed outside
of cassandra using system tools. Presumably either cassandra is
somehow connecting to the wrong port, or this is a
firewalling/os/network issue, or the 'other' cassandra is not
listening on the port. Using tcpdump/netstat -nlp should narrow that
down.

Is it possible connections only succeed in one direction for example?
