title: ssh tunnelling chain
body: <p>Here is the scenario</p>
  
  <p>I am trying to get scp access to server3, but there is only public ssh access to server 1. To ssh to server3, I have to ssh to server1, ssh to server2, then ssh to server3.</p>
  
  <p>My hopeful end result would be that I could WinSCP to localhost:8022 and it will give me file access to server3.</p>
  
  <p>I am trying to use ssh tunnels, but through all the tutorials and questions I have read none seem to work for this scenario.</p>
  
  <p>I am using putty on Windows.</p>
  
  <p>Any suggestions would be truly helpful. Thank you.</p>
