title: new cassandra node can't gossip with seed
body: <p>I am trying to spin up a new node using cassandra 2.0.7. Both nodes are at Digital Ocean. The seed node is up and running and I can telnet to port 7000 on that host from the node I'm trying to start.</p>
  
  <pre><code>[root@cassandra02 apache-cassandra-2.0.7]# telnet 10.10.1.94 7000
  
  Trying 10.10.1.94...
  
  Connected to 10.10.1.94.
  
  Escape character is '^]'.
  </code></pre>
  
  <p>But when I start cassandra on the new node I see the following exception:</p>
  
  <pre><code>INFO 00:01:34,744 Handshaking version with /10.10.1.94

  <p>I'm using the murmur3 partition on both nodes and I have the seed node's IP listed in the cassandra.yaml of the new node. I'm just wondering what the issue might be and how I can get around it.</p>
