title: Can't connect to cassandra node from different host
body: <p>I have a cassandra node at a machine. When I access cqlsh from the same machne it works properly.</p>
  
  <p>But when I tried to connect to it's cqlsh using "192.x.x.x" from another machine, I'm getting an error saying</p>
  
  <p>Connection error: ('Unable to connect to any servers', {'192.x.x.x': error(111, "Tried connecting to [('192.x.x.x', 9042)]. Last error: Connection refused")})</p>
