  1. Windows UNIX Integration in the Enterprise Paul Hinsberg, MCSE, MBA CEO, CRSD Inc http://www.crsdinc.com

  2. Integration • File/Printing • Active Directory/Networking • Password/Authentication • Emulation • Application Interoperability Windows UNIX Integration PaulHins@CRSDINC.COM

  3. File and Printing • Printing • Windows and NFS • UNIX Samba/PCNetlink Windows UNIX Integration PaulHins@CRSDINC.COM

  4. LPR/LPD • Microsoft provides a LPR client and LPD daemon (server) • Windows can print to UNIX LPD via the LPR client • Windows can receive print jobs from UNIX LPR • Microsoft LPR/LPD is based on RFC1179 Windows UNIX Integration PaulHins@CRSDINC.COM

  5. Control Panel ,Network and Dial-up Connections Click Advanced and Optional Network Components Select Other Network File and Print Services LPR/LPD Setup Windows UNIX Integration PaulHins@CRSDINC.COM

  6. Creating Printers • To connect to a UNIX LPD printer, you will need to create a LPR printer port when creating the printer. • To allow UNIX LPR clients to connect, set the TCP/IP Printer Service to start automatically in Control Panel and then share the printer. Windows UNIX Integration PaulHins@CRSDINC.COM

  7. Printer Issues • HP-UX has some particulars (see Q150154) • Control Characters and Post Script can sometimes create issues. (see Q124735) Windows UNIX Integration PaulHins@CRSDINC.COM

  8. File Share • UNIX utilizes Network File System (NFS) for sharing files systems information • Both UNIX and Windows have emulation and compatibility components Windows UNIX Integration PaulHins@CRSDINC.COM

  9. Windows NFS • Services for UNIX (SFU) is a Microsoft product that provides a variety of compatibility and integration solutions • SFU contains an NFS Client and NFS Server • SFU is a separate product for sale from Microsoft (SFU 3.0 retails at $99) http://www.microsoft.com/windows/sfu/default.asp Windows UNIX Integration PaulHins@CRSDINC.COM

  10. NFS Client • Once installed can mount UNIX published NFS using standard NET Use and Explorer Commands • MOUNT, is also available to Windows Users • UNIX systems must be set to allow the Windows client to connect. The client’s machine name is specified. Windows UNIX Integration PaulHins@CRSDINC.COM

  11. NFS Server • Provides ability to create NFS Shares • Access is controlled via Permissions allow machine names or groups of machines names • Root Access can also be provided. Windows UNIX Integration PaulHins@CRSDINC.COM

  12. NFS Server Permissions • NFS Server also will translate UNIX user permissions • Microsoft DACL are translated to UNIX style permissions list • User Name Mapping can be used to map SIDs (Windows Users) to UNIX UIDs and GIDs more on UNM and authentication later Windows UNIX Integration PaulHins@CRSDINC.COM

  13. UNIX Samba • Samba is opensource freeware that installs on UNIX machines to provide File and Print services to Windows Clients • Once configured, the UNIX system presents itself as a Windows Machine and can appear in the Network Neighborhood. • Active Directory publications and DFS Shares can be created to point to the Samba Shares. Windows UNIX Integration PaulHins@CRSDINC.COM

  14. Samba Information • Samba is configured like many UNIX systems via a series of files. • More information can be acquired by visiting: Main Samba Site http://www.samba.org/ Samba Intro http://us1.samba.org/samba/docs/SambaIntro.html Windows UNIX Integration PaulHins@CRSDINC.COM

  15. Samba Issues • Master Browser functionality can sometimes interfere with Windows Operation (Q168821) • Configure information in the smb.conf can correct most of the issues. • os level, domain master, and preferred master settings should be made to disable browser election functions. Windows UNIX Integration PaulHins@CRSDINC.COM

  16. Active Directory / Networking • Active Directory relies on some network functions like DNS which both UNIX and Windows can provide • Active Directory contains information on objects in an environment including users and devices Windows UNIX Integration PaulHins@CRSDINC.COM

  17. DNS Compatibilty • AD is reliant on correctly configured DNS and hierarchy • Any DNS server for Active Directory must support the SRV record type and allow dynamic updates per RFC 2136 Windows UNIX Integration PaulHins@CRSDINC.COM

  18. DNS Issue • UNIX servers allowing Dynamic Updates can be a security risk • Experience has shown that Microsoft DNS servers can have performance issues under extreme conditions. (Note that .NET server has made some vast improvements.) Windows UNIX Integration PaulHins@CRSDINC.COM

  19. AD User Integration • User Name Mapping • Provides a way for user accounts to be mapped to UNIX UID and GID information • Relies on UNIX User gathering tools like PCNFS and NIS • Provides for one-to-many mappings Windows UNIX Integration PaulHins@CRSDINC.COM

  20. PCNFS • Older style of manual information exchange of passwd files • Generally not highly secure • User in smaller installation or fore SFU 1.0 compatibility Windows UNIX Integration PaulHins@CRSDINC.COM

  21. UNIX Network Information Service (NIS) • Used to group UNIX systems into administrative units • Coordinates the username, passwords, and other files between multiple systems. • Windows Server for NIS integrates directly into Active Directory – expanding the schema to include UNIX style information Windows UNIX Integration PaulHins@CRSDINC.COM

  22. NIS Installations • UNIX Daemon must be installed if Windows is to propagate user information • UNIX module must be installed on UNIX systems that will propagate changes back to Windows • Server for NIS must be installed on a Windows machine and be allowed to alter the schema Windows UNIX Integration PaulHins@CRSDINC.COM

  23. Password Synchronization • Is installed with NIS, but does not require NIS • Has a UNIX Daemon used to accepting changes from windows (encrypted) • Has a UNIX module for allowing changes on UNIX to propagate back to Windows • Works with NIS domains or individual machines Windows UNIX Integration PaulHins@CRSDINC.COM

  24. Emulation • Provide Windows or UNIX style commands through translation • Typical form is that of a virtual machine or second OS on the same system • Examples • VMWare www.vmware.com • Win4Lin www.netraverse.com Windows UNIX Integration PaulHins@CRSDINC.COM

  25. Application Compatibility • Unlike emulation, ported APIs allow for a more native method of running code. • Windows Compatibility on UNIX • WINE wine.codeweavers.com • Lindows www.lindows.com • UNIX Compatibility on Windows • Services for UNIX (Interix) http://www.microsoft.com/windows/sfu/default.asp Windows UNIX Integration PaulHins@CRSDINC.COM

  26. UNIX Application Integration • Windows SFU comes with the Interix subsystem which runs in kernel mode on the Windows platform. • Running in kernel mode leads to highly integrated operations and enhanced performance. • SFU comes with many utilities and functions common in a UNIX environment: Windows UNIX Integration PaulHins@CRSDINC.COM

  27. SFU Utilities • SFU Includes • Telnetd • Nfs • NIS & PCNFS Servers • Password Synch • C-shell, Kron Shell • Cron & Remote Shell utilitiese • Interix Subsystem Windows UNIX Integration PaulHins@CRSDINC.COM

  28. Application Integration • WINE allows for the running of a good percentage of Windows programs • Allows for code developed in Windows C/C++ to be ported • Running as an integrated part of the kernel gives it a performance gain over emulators. Windows UNIX Integration PaulHins@CRSDINC.COM
