Press Release March 1, 2006
Combined SSH Server and Clients for the Interix Technology in Microsoft Windows Services for UNIX (SFU) or the Subsystem for UNIX-based Applications (SUA) in Windows Server 2003 R2 installing prerequisite software

Interop Secure Shell also features a graphical SFTP client for convenient, secure "drag and drop" file transfer.

Interop Secure Shell 2006 is derived from the OpenSSH 4.2 Interix port available as a free download from our "Slash Tools" website at www.interopsystems.com/tools. 
This commercial edition has several added features:

• Interop Secure Shell is released under a standard commercial software license, not an open source license. This means that a commercial entity (Interop Systems) is providing all the technical support and critical updates for this important piece of security software. (Interop Systems has been working with both the OpenSSH and Interix technology for over ten years.)
   
• The first year of annual maintenance (security patches, automated updates and version upgrades) is included with both individual and volume licenses.
   
• Interop Secure Shell includes Interop's own updating technology to facilitate unattended installation and automated distribution of updates to one, ten or a thousand machines.
• Secure shell access is provided to an Interix ksh, csh, bash or zsh shell. At the request of our user community, the commercial version also includes the ability to access Win32 character-based applications, such as cmd.exe. Access can come from any type of remote terminal, not just VT100s and xterms -- from an IBM tn3270 to a ksh or cmd.exe, for example.
   
• Network authentication works seamlessly on any Windows machine where the user is already authenticated in Active Directory. All SSH log-in events are recorded in the Windows Event log thereby facilitating compliance with security policies.
   
• The Installation uses a standard Windows Installer (MSI) install / uninstall process, accessible from the Control Panel, Add/Remove Programs.
   
• Terminal SSH and SFTP clients and the graphical SFTP client can be launched from the Windows 'Start | All Programs' user interface. A Session Manager lets you save your sessions for future access.
   
• Interop Secure Shell is also the ideal cross-platform SSH client for accessing the ubiquitous OpenSSH that ships with most flavors of UNIX and Linux, and Solaris Secure Shell (derived from OpenSSH). It is also compatible with other commercial Secure Shell products.
  
  Interop Secure Shell has several optional centralized administration features:
• Configuration of the Interop SSHD Server is facilitated by use of a Microsoft Management Console (MMC snap-in) accessible from the Windows 'Start | All Programs' user interface.
• Interop Secure Shell’s automated update system allows system administrators to first test updates and patches and then upload approved updates to a secure location. Secure Shell users will then automatically receive the update at a scheduled time or on next logon.
• Interop Secure Shell includes an additional level of access control and logging by utilizing OpenSSH functionality and syslogd improvements ported to Interix. These provide for optional centralized control of:

  • User level restrictions on which files are accessible via sftp and scp, port forwarding and X-11 tunneling use;
  • Additional logging of files transferred and programs executed;
  • Implementation of a “chroot jail” to create a safe user environment on systems that allow remote access via secure shell.

Installing Prerequisite Software
Interop Secure Shell requires Microsoft's UNIX-style subsystem technology.  This is available by downloading Windows Services for UNIX 3.5 (Interix subsystem) directly from Microsoft: SFU 3.5 download.  The standard download is sufficient.
If you have Windows Server 2003 R2 installed, then the Subsystem for UNIX-based Applications (SUA) is available to you from the Control Panel | Add or Remove Programs | Add/Remove Windows Components.  Once you have added in the SUA, then you need to download the Utilities package from the Start menu: Start | All Programs | Subsystem for UNIX-based Applications | Download Utilities for Subsystem for UNIX-based Applications.  That will take you to Microsoft's download site for the SUA utilities.
Microsoft just announced that the SUA will also ship as part of the Windows Vista operating system scheduled for release later this year.  See Microsoft's announcement.
