title: Use SSH to copy files from one webserver to another
body: <p>I am logged in on a webserver and want to push the files to another webserver via FTP/port 21. </p>
  
  <p>I tried it with this:</p>
  
  <pre><code>rsync -avz -e 'ssh -p 21' license.txt user@ip:/httpdocs/
  </code></pre>
  
  <p>My assumption is that license.txt is pushed to /httpdocs/ on the other server, but nothing happens. Normally I must have been prompted to enter the password for the user on the remote ip address, hm?</p>
