title: Connecting to Oracle on a Vagrant box from OS X
body: <p>I have a Oracle 10g installed on a CentOS 6 Vagrant box (VM) running on OS X Lion. On the CentOS I can run <code>sqlplus</code> for the oracle user (not root). I can ping to my Vagrant box using it's IP from <code>OS X</code> and vice-versa. I am also forwarding the port 1521 from <code>CentOS</code> to port 1521 on <code>OS X</code>.</p>
  
  <p>I want to connect to the Oracle on my VM using SQLDeveloper on my OS X. I keep getting the following error</p>
  
  <blockquote>
    <p>Status : Failure -Test Failed: IO Error: The Network Adapter could not establish the connection</p>
  </blockquote>
  
  <p>What can be wrong? </p>
