title: Navicat can't connect mysql server via ssh
body: <p>I can connect the server via ssh and login the mysql via <code>mysql -u root -h localhost -p</code> without any problem. But why Navicat's ssh login doesn't work?</p>
  
  <p>Server Environment:</p>
  
  <pre><code>Ubuntu 10.04.1 LTS
  mysql  Ver 14.14 Distrib 5.1.67, for debian-linux-gnu (i486) using readline 6.1
  </code></pre>
  
  <p>Why this error info prints the public ip of the server when I'm using localhost to connect mysql?</p>
