Description:Many of the web hosting companies has blocked port 3306 to prevent access from outside, to defend against from security threats. As a consequence, users are required to use web-based client to access their MySQL Server provided by the hosting companies. These web-based clients are usually not visually appealing with annoying page refreshes.
However, with the increasing demand from users to connect from remote MySQL clients, some web hosting companies provides SSH Connection which allows user to login remotely across the Internet and support connection through the software based clients.
SSH stands for Secure Shell and is a communication protocol for connecting to remote computers over TCP/IP. Encryption provides confidentiality and data integrity, and SSH uses public-key cryptography to authenticate the remote computer and to allow the remote computer to authenticate the user if necessary.
There are several benefits to using SSH:
* Connect to a MySQL server from behind a firewall when the MySQL server port is blocked.
* Automate the authentication of users, no passwords sent in plain text to prevent the stealing of passwords.
* Offers Multiple strong authentication methods that prevent such security threats as spoofing identity.
* Offers Encryption and compression of data for security and speed.
* Secure the file transfer.

In the following section, we have selected one of a popular hosting companies and show how a SSH Connection to the MySQL Database can be established with Navicat.
Tutorial on how to establish SSH Connection to a MySQL database hosted in Dreamhost
DreamHost provides shell access to all of its customers, but it needs to be specifically enabled for each user added to a customer's account. By default, the Type of the user is set to be “FTP”, you will need to enable the shell access before you can connect through SSH.
Enabling the Shell access for an existing user:
1) In your Control Panel, Visit User > Manage Users.
2) Click the [ edit ] link located next to the user you'd like to enable shell access for.
3) Check the 'Enable ssh/telnet?' box for that user.
4) Leave the 'Type' as it is unless you need it to be something other than bash.
5) Click Save
Keep in mind that it takes about 20 minutes for this change to take effect.
After changing the user account to Shell Type, you’ll also need to grant rights for your local machine to connect to the database server, before you can connect remotely by Navicat. This must be done for all MySQL user accounts you plan on logging in from your local machine.
Granting rights for your local machine:
1) Login to your Dreamhost Control Panel
2) Select the Manage MySQL link under the Goodies section.
3) Under the Database(s) on this server section, find the desired database and click the username you wish to grant access to.
4) Under the section titled Allowable Hosts, type in the domain or subdomain or your IP Address your local machine identifies itself as on the public internet.
5) Click Save
You have completed the settings required in your Dreamhost account, now you will go to Navicat to create the Connection.
In Navicat, click the Connection button to New a Connection.
In the General Tab of the Connecting Setting box,
Hostname/IP address: the hostname of your mysql server at dreamhost, you can check this at Control Panel > Goodies > Manage MySQL
Port: 3306 (this is the default port number for the MySQL Server)
Username: username with access right granted in Manage MySQL section
Password: password
In the SSH Tab of the Connecting Setting box,
Hostname / IP Address: machine_name.dreamhost.com
Port: 22 (this is the port for SSH connection)
Username: username which you have changed the account to Shell type in Dreamhost
Password: password
To test if the Connection settings are correct, you may click the “Test Connection” button to check.
