title: Linux how to start "sftp-server"?
body: <p>I'm not very familiar with it but there is installed <code>openssh/sftp-server</code> (by a vendor before) on <code>RHEL</code> and it was well running before i reboot the server. Then when i check after rebooted:</p>
  
  <pre><code># ps aux | grep ftp
  </code></pre>
  
  <p>No <code>sftp</code> is running but <code>sshd</code> is.</p>
  
  <p>So how do i do to have this <code>sftp</code> running please?</p>
