title: Go from AWS root to ec2-user
body: <p>Using unix, I'm able to ssh successfully into my instance using the following:</p>
  
  <pre><code> ssh -i ~/.ssh/seis_v3.pem root@52.5.233.876
  </code></pre>
  
  <p>However, when I try to login as ec2-user instead of root, I get denied.  Is there a way once in root@52.5.233.876 to change directory or permissions to get onto ec2-user?  Thank you.</p>
