title: How to close this ssh tunnel?
body: <p>I opened a ssh tunnel as described in this post: <a href="https://stackoverflow.com/questions/2807118/zend-db-how-to-connect-to-a-mysql-database-over-ssh-tunnel">Zend_Db: How to connect to a MySQL database over SSH tunnel?</a></p>
  
  <p>But now I don't know what I actually did. Does this command affect anything on the server?
  And how do I close this tunnel, because now I can't use my local mysql properly.</p>
  
  <p>I use OSX Lion and the server runs on Ubuntu 11.10.</p>
