title: How login FTP server using ssh private key and credential
body: <p>Hope everyone is doing well, 
  I have one new request from the client.</p>
  
  <p>We sends files from our server to one FTP server.
  But now client want to use new credential and private ssh key for that FTP server and he shared the same with us.</p>
  
  <p>We have opened the new port also, but I am unable to login into FTP server. Did I need to do something to login or is their different ways to login for the same.</p>
  
  <p>Regards,
  Mustafa</p>
