Overview

The Telnet protocol is used to establish a connection with a server which provides a virtual terminal session for a user. Its functionality is similar to how character based consoles and serial terminals work, enabling a user to login to the server, execute commands and interact with applications running on the server. The class provides an interface for establishing the connection, negotiating certain options (such as whether characters will be echoed back to the client) and handling the standard I/O functions needed by the program.

The class also provides methods that enable a program to easily scan the data stream for specific sequences of characters, making it very simple to write light-weight client interfaces to applications running on the server. The CTelnetClient class can be combined with the CTerminalEmulator class to provide complete terminal emulation services for a standard ANSI or DEC-VT220 terminal.

This class supports secure connections using the standard SSL and TLS protocols. To establish a secure connection to the server using the Secure Shell (SSH) protocol, use the SocketTools CSshClient class.

Requirements

The SocketTools Library Edition libraries are compatible with any programming language that supports calling functions exported from a standard dynamic link library (DLL). If you are using Visual C++ 6.0 it is required that you have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools and have the current Windows SDK installed.

This library is supported on Windows XP, Windows Server 2003, Windows Vista, Windows 7 and Windows Server 2008. If you are using Windows XP, it is required that you have Service Pack 3 (SP3) installed. It is recommended that all service packs and critical updates to the Windows operating system be installed.

This product includes both 32-bit and 64-bit libraries. Native 64-bit CPU support requires the latest 64-bit version of Windows XP Professional, Windows Server 2003 or later versions of the Windows operating system.

Distribution

When you distribute your application that uses this library, it is recommended that you install the file in the same folder as your application executable. If you install the library into a shared location on the system, it is important that you distribute the correct version for the target platform and it should be registered as a shared DLL. This is a standard Windows dynamic link library, not an ActiveX component, and does not require COM registration.
