VanDyke Software’s VShell 3.6 Secure Shell server delivers new tools for system administrators to restrict access to Windows and UNIX systems

The 3.6 release of the VShell server adds ability to limit user access to SSH2 commands and services through the public key. New VanDyke ClientPack 6.5 release with VRALib for scripting Secure Shell connections.

Albuquerque, N.M. (December 10, 2009) — VShell® 3.6 server from VanDyke Software®, Inc. helps organizations transfer files and secure data with fine-grained access control and configuration options. The 3.6 release announced today provides new controls over user access to commands and subsystems through public key "private use" headers.

"With the complexity of network environments, system administrators want Secure Shell servers with more control over end-user access to files and services," said Jeff P. Van Dyke, President of VanDyke Software. "VShell 3.6 provides that by allowing admins to restrict users to commands or subsystems through the same public key that authenticates the user."

VShell 3.6 also improves back-end control with the ability to set environment variables with SSH2 on the Windows server and expands logging capability for UNIX and Linux versions.

On the client side, the official release of VanDyke ClientPack 6.5 adds to its utility toolkit with VRALib, a Windows COM and .NET API and DLL for scripting Secure Shell connections. The VRALib API provides quick access to a variety of functions including controlling SSH2 connections, sending SSH2 commands and collecting output, performing SFTP file transfer and remote file management, setting up tunnels to encrypt TCP traffic, adding host keys to the host key database, and adding keys to the SSH2 authentication agent.

The VShell Secure Shell server replaces Telnet and FTP for secure network administration and end-user access on Windows and UNIX platforms. Precision control over privileges, the ability to fine-tune your Secure Shell environment, and a wide selection of strong authentication methods give you a flexible solution that grows with your evolving security policies. VanDyke Software also develops client applications for use with VShell and other Secure Shell servers. SecureCRT® is the tool of choice for IT professionals who are responsible for network administration and end-user access where security is critical, combining a feature-filled terminal emulator with the security of the Secure Shell (SSH) protocol. SecureFX® is a versatile file transfer application that supports SFTP, FTP over SSL, as well as standard FTP. The VanDyke ClientPack combines a powerful set of automation tools and command-line utilities for securely automating routine file transfer, shell, and public-key administration tasks on Windows, Linux, and UNIX.
