title: Why not able to start SSH shell though permissions are set?
body: <p>Due to a recent hack of my servers I am in some kind of ultimate restriction taste and thus wanted to limit the permissions of all the root folders like so:</p>
  
  <pre><code>chmod o-x /*
  </code></pre>
  
  <p>To enable login for other users again, I do:</p>
  
  <pre><code>chmod o+x /home
  </code></pre>
  
  <p>Now, I have another user which is not root and which should be the only one allowed to login, but it cant - the SSH authentication itself works but then this error appears:</p>
  
  <blockquote>
    <p>/bin/sh: Permission denied</p>
  </blockquote>
  
  <p>Seems easy to grant permissions to the bin folder like so:</p>
  
  <pre><code>chmod o+x /bin
  </code></pre>
  
  <p>But I still get the same Permission denied message.</p>
  
  <p>Whats going on here?</p>
