How to use HttpOptions?

In new SB have HttpOptions.
but how to use it?

Here is an article from the SecureBridge help center, which will be added in the next build of SecureBridge.
SecureBridge supports work through a proxy only when using an HTTP tunnel. Implementation of support for work through a proxy without using an HTTP tunnel is impossible, since the traffic is redirected through the proxy to the HTTP server.

Here is an article from the SecureBridge help center, which will be added in the next build of SecureBridge:
Connection through HTTP tunnel
Sometimes client machines are shielded by a firewall that does not allow you
to connect to server directly at the specified port. If the firewall allows
HTTP connections, you can use SecureBridge together with HTTP tunneling
software to connect to SSH server.

SecureBridge supports HTTP tunneling based on the PHP script.

An example of the web script tunneling usage can be the following: you have
a remote website, and access to its database through the port of the
database server is forbidden. Only access through HTTP port 80 is allowed,
and you need to access the database from a remote computer, like when using
usual direct connection.

You need to deploy the tunnel.php script, which is included into the
provider package on the web server. It allows access to the database server
to use HTTP tunneling. The script must be available through the HTTP
protocol. You can verify if it is accessible with a web browser. The script
can be found in the HTTP subfolder of the installed provider folder, e. g.
%Program Files%\Devart\SecureBridge for Delphi X\HTTP\tunnel.php. The only
requirement to the server is PHP 5 support.

To connect to the database, you should set TScSSHClient parameters for usual
direct connection, which will be established from the web server side, the
HttpOptions.Enabled property to True, and set the following parameters,
specific for the HTTP tunneling:

Property Mandatory Meaning
HttpOptions.Url Yes Url of the tunneling PHP script. For example, if the
script is in the server root, the url can be the following:
http://localhost/tunnel.php.
HttpOptions.Username, HttpOptions.Password No Set this properties if the
access to the website folder with the script is available only for
registered users authenticated with user name and password.

Connection through proxy and HTTP tunnel

Consider the previous case with one more complication.

HTTP tunneling server is not directly accessible from client machine. For
example, client address is 10.0.0.2, server address is 192.168.0.10, and the
SSH server listens on port 22. The client and server reside in different
networks, so the client can reach it only through proxy at address 10.0.0.1,
which listens on port 808. In this case in addition to the
TScSSHClient.HttpOptions options you have to setup a
HttpOptions.ProxyOptions object as follows:

Code: Select all

ScSSHClient := TScSSHClient.Create(self);
ScSSHClient.KeyStorage := ScFileStorage;
ScSSHClient.HostName := '192.168.0.10';
ScSSHClient.Port := 22;
ScSSHClient.User := 'test';
ScSSHClient.Password := 'test';
ScSSHClient.HttpOptions.Enabled := True;
ScSSHClient.HttpOptions.Url := 'http://server/tunnel.php';
ScSSHClient.HttpOptions.ProxyOptions.Hostname := '10.0.0.1';
ScSSHClient.HttpOptions.ProxyOptions.Port := 808;
ScSSHClient.HttpOptions.ProxyOptions.Username := 'ProxyUser';
ScSSHClient.HttpOptions.ProxyOptions.Password := 'ProxyPassword';
ScSSHClient.Connect;

Note that setting parameters of ScSSHClient.HttpOptions.ProxyOptions
automatically enables proxy server usage.
