title: SSH multiple HOP
body: <p>I have 3 workstations</p>
  
  <ul>
  <li>ortro (my client)</li>
  <li>idrauser@idra (the middle)</li>
  <li>cerberouser@cerbero (the destination)</li>
  </ul>
  
  <p>On idra:</p>
  
  <pre><code>ssh -L 9999:idra:22 cerberouser@cerbero
  </code></pre>
  
  <p>On otro:</p>
  
  <pre><code>ssh idrauser@idra -p 9999
  ssh: connect to host idra port 9999: Connection refused
  </code></pre>
  
  <p>I cannot modify the sshd_config in ortro. I need to setup a tunnel between idra and cerbero and then use it from ortro</p>
  
  <p>Thanks a lot
