title: autossh not working and run without any error message
body: <p>I have no problem when running this command on ssh , but in autossh its not working.
  the list of command i have done till now :</p>
  
  <pre><code>1- ssh-keygen -t rsa
  2- cp id_rsa.pub /home/sshUser/.ssh/authorized_keys2/
  3- cp id_rsa /home/sshUser/.ssh/authorized_keys2/
  4- autossh -fNg -L 3307:127.0.0.1:3306 sshUser@10.100.20.25
  </code></pre>
  
  <p>and after the last line nothing happen.
  ssh still done and ive check it with : "sudo lsof -i -n | egrep '\'"
  but if i use ssh instead of autossh it works.</p>
