SSH Secure Shell software development tool for Borland Delphi

ActiveSocket is a Network Communication component for Windows Developers. It runs on any 32 bit and 64 bit Windows Platform, incl. Windows 7, Windows 2008, Windows 2003, Windows 2000, Windows Vista and Windows XP.
It features many IP protocols, incl.: SSH (Secure Shell), RSH (Remote Shell), HTTP(s), FTP, ICMP Ping, NTP, SNMP v1/v2c (Get,GetNext,Set), SNMP MIB translation, SNMP Trap Sender, SNMP Trap Receiver, Telnet, DNS, TCP, UDP, IP-to-Country, Wake-On-LAN and more. Samples are included many popular development platforms, incl. Visual C# .NET, Visual Basic .NET, ASP .NET, Visual Basic, Visual C/C++, ASP, Java, Javascript, PHP, Borland Delphi, Borland C++ Builder, ColdFusion.

SSH Secure Shell is a secure telnet internet protocol to allow exchange of data. On the first place, it is used on Unix and Linux systems to access shell accounts and shell scripts. SSH was designed to replacement the insecure TELNET protocol and other insecure remote shell protocols (incl. RSH, Remote Shell). SSH uses the well-known public-key cryptographic algorithm to authenticate the remote host.

ActiveSocket can be well integrated into Borland Delphi environments. This document describes how ActiveSocket can be integrated into Borland Delphi projects.

Step 1: Download and install the ActiveSocket Toolkit

Download the ActiveSocket from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new Delphi Project

Launch Borland Delphi (for instance 'Delphi 2005') from the Start menu. Choose 'New' from the 'File' menu and select your preferred kind of application, for instance: 'VCL Forms Application - Delphi for Win32'. A new Form is displayed in the workspace.

Step 3: Refer to the ActiveSocket Library and create the objects

Now that a new project has been created, you must add a reference to ActiveSocket in the project to be able to use the ActiveSocket object. To do so, choose 'Import Component...' from the 'Component' menu. The Import Components' dialog appears. Select 'Import a Type Library': Delphi

The interface code is generated now and is shown in the ASOCKETLib_TLB tab of the project.

Step 4: Declare and create the object

From the Project Manager, open Unit1.bas and add the ASOCKETLib_TLB to the 'Uses' statement to refer to the ActiveSocket library: Delphi

In the 'private' or 'public' section, declare the following objects:

   objSsh       : ISsh

You can now create the objects, for instance in the 'FormCreate' function:

   objSsh       := TSsh.Create(Form1).DefaultInterface;
