title: pem file permissions on Bash on Ubuntu on Windows
body: <p>I am attempting to login to my box using my .pem file however I get the error</p>
  
  <pre><code>@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
  @         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
  @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
  Permissions 0555 for './arete-server.pem' are too open.
  It is required that your private key files are NOT accessible by others.
  This private key will be ignored.
  bad permissions: ignore key: ./arete-server.pem
  Permission denied (publickey).
  </code></pre>
  
  <p>chmod 400 doesn't work on Bash on Ubuntu on Windows and the best permissions I can give it is -r-xr-xr-x</p>
  
  <p>Any idea how to get permissions to a point where I can use this pem file?</p>
