title: how to transfer data between local and remote server connected via intermediate server?
body: <p>I can login by <code>ssh -X servA</code> from <code>local</code>, then <code>ssh -X servB</code> from <code>servA</code></p>
  
  <p>To copy data from <code>local</code> to <code>servB</code>, I <code>scp</code> files from <code>local</code> to <code>servA</code>, then from <code>servA</code> to <code>servB</code>.</p>
  
  <p>Is it feasible to copy files from <code>local</code> to <code>servB</code> directly and vice versa?</p>
