title: In Elixir/Erlang, which port is used for `Node.connect`?
body: <p>One can init a Elixir node by iex using:</p>
  
  <pre><code>iex --sname node1@10.99.1.50 --cookie foo
  </code></pre>
  
  <p>And then another one can connect this node in REPL using:</p>
  
  <pre><code>Node.connect(:"node1@10.99.1.50")
  </code></pre>
  
  <p>It seems the connection is over TCP protocol. However, I didn't find a parameter in <a href="http://erlang.org/doc/man/net_kernel.html#connect_node-1" rel="noreferrer">document</a> to specify which port is used. Does anyone have any ideas about this?</p>
