1.6 SSH Tunneling
This section describes how to setup SSH connection.
If for some reasons direct connection via port 3306 is not allowed, there is another way - secure SSH connection. Actually, SSH is a kind of tunnel between two computers - your and your server. Look here for more details about SSH. Please make sure that SSH access is enabled and configured on your hosting account. Please contact your hosting company to enable and configure it. You will NOT be able to use SSH connection until Hosting Company enables it.
The only info you need, if you checked authentication method by password, is SSH username, password, and remote port number. You're welcome to contact your hosting company to find out your username and password and to verify if the 22 port is used.
If you had provided a private key to connect via SSH protocol, check next type of authentication (by 'Private key') and load it from a file that is contained in your computer.
Clicking 'Test connection' button helps you check whether all settings are entered correctly and allows you successfully proceed.
Note: SSH settings do not override MySQL settings. To connect to your database using SSH you must specify all required MySQL parameters (Direct Connection to MySQL Server) as well as SSH.
