Editing Windows Services for UNIX (section)

==Releases==

===1.0===
Microsoft produced at least one beta release of the initial version of SFU before its final release in February 1999. This release, in [[English language|English]] only, was supported on the [[Windows NT 4.0]] SP3+ for [[x86]] and [[DEC Alpha|Alpha]] platforms. This is the only known release to support Alpha. It included a demonstration version of the [[MKS Toolkit]] along with the following components:

* [[Telnet]] server
* Telnet client
* UNIX Utilities (from [[MKS Inc.|MKS]])
* Client for [[Network File System|NFS]]
* Server for NFS
* Server for NFS Authentication
* Windows NT to UNIX password-synchronization
* Help files and documentation

===2.0===
This second installment of SFU was released April 2000 and was also for English; however, a [[Japanese language|Japanese-language]] release appeared just two months later in June 2000. Both ran on Windows NT 4.0 SP4+ and [[Windows 2000]] on x86 platforms with [[Internet Explorer]] 4.01+. SFU 2.0 supported the following UNIX versions: [[Solaris (operating system)|Solaris]] 2.6+, [[HP-UX]] 10.2+, [[IBM AIX|AIX]] 4.2+, [[Tru64 UNIX]] 5.0+, and [[Red Hat Linux]] 5.1+. It included the following components:
* Server for [[Network File System|NFS]] (NFSServer)
* Client for NFS (NFSClient)
* Gateway for NFS (NFSGateway)
* Server for PCNFS (Pcnfsd)
* User Name Mapping (Mapsvc)
* Server for NFS Authentication (NFSServerAuth)
* Server for [[Network Information Service|NIS]] (NIS)

* Telnet server (TelnetServer)
* Password synchronization (PasswdSync)
* [[ActiveState]] ActivePerl (Perl)
* UNIX utilities (UnixUtilities)
* [[Cron]] service (CronSvc)
* [[Remote Shell|Rsh]] service (RshSvc)
There were subsequent updated OEM releases SFU 2.1, SFU 2.2, and SFU 2.3.

===3.0===
This version, released in May 2002, was the first release to include the [[Interix]] subsystem. Previously Microsoft had released Interix 2.2 (actually version 2.2.5) as a separate product around the same time frame as SFU 2.0. This SFU release included Interix release 3.0 (commonly called the "version" as reported by '''uname -r''') with an internal Microsoft version of 7.0 that relates to internal build sequences. This Interix release contained significant technical extensions from the Interix 2.2 release such as a rooted file system and setuid functionality that were entirely based on the Softway Systems' [[Interix]] development codenamed "Firebrand". This was also released in English and followed by a later release in Japanese in October 2002, adding [[Internationalization and localization|internationalization]] support. Both supported Windows NT 4.0 SP6a+, Windows 2000, and [[Windows XP]] Professional on x86 platforms with Internet Explorer 5.0+. The MKS Toolkit was no longer included. It included the following components:
* Base Utilities for Interix (BaseUtils; including [[X Window System|X11R5]] utilities)
* UNIX Perl for Interix (UNIXPerl)
* Interix SDK (InterixSDK; including headers and libraries for development and a wrapper for [[Microsoft Visual Studio|Visual Studio]] compiler)
* GNU Utilities for Interix (GNUUtils, about 9 utilities in total)
* GNU SDK for Interix (GNUSDK; including [[GNU Compiler Collection|gcc]] and g++)
* NFS Client for Windows (NFSClient)
* NFS Gateway for Windows (NFSGateway)
* NFS Server for Windows (NFSServer)
* NIS Server for Windows (NIS)
* Password Synchronization (PasswdSync)
* Windows Remote Shell Service (RshSvc)
* Telnet Server for Windows (TelnetServer)
* NFS User Name Mapping (Mapsvc)
* NFS Authentication Server (NFSServerAuth)
* PCNFS Server (Pcnfsd)
* ActiveState Perl (Perl)

===3.5===
This was the final release of SFU and the only release to be distributed free of charge. It was released January 2004 and included both English and Japanese versions for Windows 2000, Windows XP Professional, and [[Windows Server 2003]] (original release only{{efn|Only works on "R1", not on R2}}) on x86 platforms with Internet Explorer 5.0+. It included Interix subsystem release 3.5 (build version 8.0) adding internationalization support (at least for the English version which did not have such until now) and [[POSIX Threads|POSIX threading]]. This release could only be installed to an [[NTFS]] [[file system]] (earlier versions supported [[File Allocation Table|FAT]]; this was for improved file-security requirements in Interix 3.5). The following UNIX versions were supported for NFS components: Solaris 7 and 8, Red Hat Linux 8.0, AIX 5L 5.2, and HP-UX 11i. It included the following components:
* Base Utilities for Interix (BaseUtils; including X11R6 and X11R5 utilities)
* UNIX Perl for Interix (UNIXPerl)
* Interix SDK (InterixSDK; including headers and libraries for development and a wrapper for Visual Studio compiler)
* GNU Utilities for Interix (GNUUtils, again about 9 utilities)
* GNU SDK for Interix (GNUSDK; including gcc and g++)
* NFS Client for Windows (NFSClient)
* NFS Gateway for Windows (NFSGateway)
* NFS Server for Windows (NFSServer)
* NIS Server for Windows (NIS)
