  - by eQuiNoX__

  I just set up a 3 node system with ip addresses "192.168.0.101", "192.168.0.102", "192.168.0.103". I have set the seeds value on the configuration of all three machines as seeds: "192.168.0.101,192.168.0.102,192.168.0.103" However, on running nodetool on any of them, only the 103 machine gets discovered. node101:/opt/cassandra/apache-cassandra-0.8.5/bin# ./nodetool ring -h 192.168.0.101 Address DC Rack Status State Load Owns Token 192.168.0.103 datacenter1 rack1 Up Normal 151.96 KB 100.00% 38174485210079977599903748344879358256 Could someone tell me where the problem lies?
