Nexgen+Server SDK description
Nexgen Server SDK - Internet SDK that allows easy development of server code and MS Windows services

The Nexgen Server SDK can help you add server functionality to new or existing C, C++, or Visual Basic projects.

Through the use of the SDKs functions and user-callbacks, developers are given complete control over the type of server they wish to implement.

The application is simple to use. First, choose the IP address to be associated with your FTP server. You can choose the 0.0.0.0 address to specify any IP address associated with your computer. Press the Start Server button to begin accepting connections on port 21. Likewise, press the Stop Server button to stop an FTP server.

You can specify whether to allow anonymous connections by checking the Allow anonymous login box. You can also set the anonymous greeting text and specify the directory for the anonymous connection. If the Set home directory as virtual root box is checked, an anonymous client will be restricted to the directory tree specified in the Anonymous home directory edit field.

Provide an administrator username and password to allow full access to your FTP site. An empty administrator username disables this type of account.

Finally, press the Update Server Stats button when a server is running to obtain statistics on that server.

Use the Nexgen Server SDK to:

· Save hours of costly development time
· Create scalable TCP and UDP servers
· Easily add FTP Server support to any application
· Add Windows Service support to any application
· Control service applications remotely with the built-in Service Control Server
· Create custom C/C++ DLLs to use with Visual Basic


Here are some key features of "Nexgen+Server SDK":

· Make use of multiple CPUs for data transfer
· I/O Completion Ports provide the benefits of speed, efficiency, and scalability
· Built-in service functionality provides allows creating and manipulating service-based applications
· Run multiple servers within the same application
· Obtain detailed information about servers running within the application's process
· Query statistics and information for users on any server
· User-defined data may be associated with any server or client
· Visual Basic applications can use DLLs written in C/C++ to process events
· Receive notifications for the current state of a server (i.e. started or stopped)
· Accept and/or reject server connections based on the client's IP address
· Assign user-defined data to connected clients for additional control
· Disconnect idle connections by setting timeout intervals
· Receive notification when a timeout is about to occur
· Disconnect users with (or without) warning
· Enumeration routines allow you to obtain useful information about clients, servers, and all IP addresses associated with the system
· Send either binary or ASCII data to connected clients
· Notification of sent data gives you the peace-of-mind that data transfers have been sent
· Received data can be processed the instant it is available
· Passive-style transfer allows clients to obtain a separate data connection
· Transferring files is simplified through the Nexgen Server's built-in file transfer routines
· Notification of client disconnects helps you keep track of active connections
· Fully compliant with the RFC-959 specification
· Assign custom permission groups to users and let the server handle the allowing of clients' FTP commands
· Tailor most FTP responses to your needs.
· Customize the greeting/goodbye text seen by FTP clients when they connect or disconnect
· Specify the user's home directory and/or restrict the user to that home directory tree
· Grant or restrict access to any directory or file access attempted by a client
· Receive notification of all aspects regarding file transfer from the beginning to the end
· Intercept data being sent to the server (either session data or file transfer data) prior to its being interpreted by the SDK
· Ability to transmit and listen on either one or two ports
· Ability to broadcast data to all listening clients
· Ability to send data to an individual client


Requirements:

· Windows NT, 2000, or XP operating system
· 10 MB hard drive space
· 512 MB RAM
· Compiler for C/C++ and/or Visual Basic


Limitations:

· The trial version of the Software shall be available for evaluation for a period of 30 days after the first time the Software is tested. After the evaluation period expires, the Software will no longer function until it is registered.
