Cassandra-cli cant connect to remote cassandra server
===

I have a cassandra server running on a server(serv1). cassandra-cli can connect to it when run on serv1. However, when i try to connect to it through some other server(serv2), i get the following exception:


    org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused

    Exception connecting to jckstore/9160. Reason: Connection refused.



I looked in cassandra.yaml and found that the property "listen_address" is configured to "localhost" and using 0.0.0.0 is severely discouraged. I tried to change localhost to serv2, ip address of serv1 but nothing worked. Even commenting out didnt help. 

Is there a way i can make my cassandra server listen on all the ip's without using 0.0.0.0
