title: Cassandra public IP not connecting
body: <p>I'm using cassandra in ubuntu server. when I try to connect using CLI with public IP address, It returns connection refused. whereas If I tried with localhost, its working fine. I made the configuration changes in cassandra.yaml and storage-conf.xml. but still I have the problem. What change should be done ?</p>
