title: MySQL: Unable to connect using TCP/IP over SSH
body: <p>We have an EC2 and RDS instance on Amazon Web Services. I usually first connect to the server using Putty and then access the database through a tunnel from my localhost.</p>
  
  <p>I am now trying to directly connect to the database using TCP/IP over SSH, but get the following error. I am able to connect other applications such as FileZilla directly without creating any tunnels, but not able to connect MySQL. Please advise. There is no entry in known_hosts file.</p>
  
  <p><strong>Error:</strong></p>
