Connection parameters

PostgreSQL Maestro allows you to connect to PostgreSQL servers directly, via Secure SHell (SSH) tunnel or HTTP tunnel.

 

•Direct connection

It is the most natural and the most preferable connection mode. Use it each time it is possible.

 

•SSH tunnel connection

If your PostgreSQL server does not allow direct connections from your remote workstations, you can establish connection to an allowed intermediate SSH server and forward all PostgreSQL commands through the Secure SHell (SSH) tunnel.

 

 More about SSH tunnel connection

 

To establish connection to intermediate SSH server and forward all PostgreSQL commands through the secure tunnel, you need to:

 

1. Check I can connect to the server directly or via SSH tunneling.

 

2. Follow the Configure SSH options link to open the SSH Options window.

 

 

3.Check Connect through the Secure Shell (SSH) tunnel and complete the following fields:

 

Host name

Specify the host name or IP of your site.

 

Port number

Enter the port number for the SSH server.
 

Enter valid User name for the remote server, select the authentication type: by password or by private key and set the Password or the path to the Private key file with the corresponding Passphrase to log in to the remote server.

 

Note: PostgreSQL host name always should be set relatively to the SSH server. For example, if both of PostgreSQL and SSH servers are located on the same computer, you should specify localhost as Host name instead of server's external host name or IP address.

 

 

•HTTP tunnel connection

HTTP tunneling is a technique used in conditions of restricted network connectivity including firewalled networks, networks behind proxy servers, and NATs. It is the slowest way and is recommended to use if the others are impossible.

 

 More about connection via HTTP tunnel

 

To connect to a remote server using an HTTP tunnel, you need to:

 

1.Upload the connection PHP script to your website. The script is named pgsql_tunnel.php and can be found under the installation folder, usually C:\Program Files\SQL Maestro Group\PostgreSQL Maestro.

 

2.Select the I have to use HTTP tunneling radio button.

 

3.Enter the connection PHP script URL, e.g. www.yoursite.com/files/pgsql_tunnel.php. You can test the connection before the profile is created. Just use Test script using default browser to open connection script in your browser, enter all the required connection parameters and use the Test connection button.

 

 

4.In case using of a proxy server use Configure tunnelling options to open the HTTP tunnelling options window and specify your proxy server connection parameters and HTTP authentication.
 

Note: You are actually connecting to your database through the PHP script on the server, so in most cases the host/server name is "localhost" unless the target server is not installed on the same server as the Web server.

 

 

Irrespectively of a connection mode you should specify common credentials as follows:

 

Host

The host name of the PostgreSQL server.

 

Port number

The TCP/IP port to use if server is not localhost.

 

User name

The username used to connect to PostgreSQL.

 

Password

The password for the user account on server.
