title: mongodb - can't initiate replica set with default configuration
body: <p>I am following <a href="http://docs.mongodb.org/manual/tutorial/deploy-replica-set/" rel="nofollow">this</a> tutorial to deploy a replica set. When I execute <code>rs.initiate()</code> I get the error "all members and seeds must be reachable to initiate set" which is strange given that the only member is localhost. </p>
