Windows NT Server

• Brief Overview of NT Server History,
  Architecture, System Concept.
• Installation procedure and related concepts.
• Material adapted from
• Inside Windows NT by Helen Custer
• Windows NT Technical Support, MS press
• Supporting IIS Server, MS press

2
Window NT OS Effort

• Bill Gate hired Dave Culter from Digital in Oct
  1988 to build a team for design a new OS.
• Dave Culter was the designer of a real time
  multitasking system called RSX-11M that ran in
  32KB on PDP-11 minicomputers. It took 18 month,
  introduced in 1973.
• He lead the effort building VMS for VAX-11
  architecture.
• He also lead a group that build the MicroVax
  workstation.

3
Window NT OS Design Goals

• Portability (RISC or CISC) written in C.
• Security (Government Certifiable Security Class
  C2 Level)
• POSIX (UNIX standard interface spec) compliance
• Compatibility
• Scalable Performance (Multiprocessor support)
• Extensibility
• Ease of Internationalization

4
NT Server

• Microsoft, multipurpose server OS.
• Provide file, print, and application services.
• Internet Information Server(IIS) comes with it.
• IIS includes WWW, ftp, and gopher servers.
• The OS required for other Microsoft BackOffice
  server components Exchange Server (Mailer), SQL
  server, Proxy server, Merchant server.
• Its Directory Service provides single logon and
  single point of administration
• Provide DNS, Dynamic Host Configuration Protocol
  (DHCP) and Windows Internet Name Service (WINS)

NT Server and NT Workstation

• Support multiple platforms (x86, AXP, MIPS,
  PowerPC)
• Multitasking, Multithread operations
• Support MS-DOS, Win-16, Win-32 applications
• Built-in networking utilities, drivers, and
  protocols.
• Support FAT, NT File system (NTFS), and CD-ROM
  File System (CDFS).

7
NT Server vs. NT Workstation

• NT Server provides enhanced features for running
  different servers.
• NT Workstation designed and tuned as multitask
  desktop operation systems.
• NT workstation can only have a limit of 10
  incoming concurrent sessions.
• The of concurrent sessions on NT server depends
  on the license (Max. of 256 inbound sessions?)

8
Workgroup vs. Domain

• Both NT workstations and NT stand-alone servers
  can be member of a Window NT workgroup.
• Each computer functions as both server and
  client. Maintains its own accounts, admin,
  security policy
• NT Domain provides improvement over the redundant
  effort of admin and security.Play Domain video
  from MS.

NT Installation Preparation

• Preparation Make sure your hardware is in NT
  Hardware Compatiblity List (HCL).
  http//www.microsoft.com/isapi/hwtest/hcl.idc?RLD
  34
• There is a NT Hardware Qualifier (NTHQ) program
  for determining hardware on x86 based computer.
• Create three NT Server Setup disks. They
  typically comes with purchase. But it also
  contains in the CD.
• These three floppy need to be formatted and
  empty.
• Type d\I386\winnt /ox to create them.

12
NT 4.0 Minimum Hardware Requirements

• CPU 486/33 or higher, MIP R4400, Digital Alpha
  AXP, Prep-compliant PowerPC
• Memory 16MB for NT Server (32 MB at least) 12MB
  for NT workstation (32MB at least)
• Hard disk space 125MB for NT Server on
  partition with 16KB clusters (200MB on partition
  with 32KB clusters) 110MB for NT Workstation.
• Display VGA or higher
• Mouse

13
System and Boot Partitions

• NT Setup program copies the hardware specific
  files to the active partition (normally C drive),
  also known as system partition.
• Setup program then prompt you to select a folder
  for installing NT OS files. This can be on other
  partition.
• The partition that contains the OS files and its
  supporting files is called boot partition.

14
Selecting File System

• You have a choice of NTFS (NT file system) and
  File Allocation Table (FAT).
• NTFS can only be accessed by NT.
• More secure.
• Provide File level security
• Used when it is the only OS in use.
• FAT
• Allow multiple OS (DOS, Linux, Win95, Win32, NT)
  to access and share
• Less secure.

  are DLL acting as comm. Pipe between IIS and a
  service.
• Backoffice connectors Exchange/ODBC connectors
• CGI
• ISAPI filters (for pre/post processing of
  packets) e.g. SSL
• Administration tools communicate through RPC.
• Logging through log file or ODBC Data Source Name

Run CGI Perl scripts on NT IIS

• www.activestate.com provides free Perl for Win32
  machines. Current build version is 513, based
  on 5.005_3 Perl release.
• The activeperl is about 4.8MB.
• After download and install, you can run Perl
  scripts from MSDOS prompt window.
• You donot have to include !/usr/bin/perl as the
  first line but it does not hurt to include for
  portability.
• Just type the ltfilenamegt.pl to execute it.
• Same distribution includes PerlIS and ISAPI dll
  for running perl CGI scripts efficiently.

36
ISAPI

• ISAPI (Internet Server Application Programming
  Interface) is an API for writing extensions to
  IIS web servers.
• Originally developed by Process Software, and
  adopted by Microsoft as its standard server API.
• It complements or replaces the Common Gateway
  Interface (CGI).
• ISAPI's main advantage over CGI is that it uses
  dynamic-link library (DLL) function calls to
  communicate with extension components, rather
  than environment variables and standard I/O, as
  CGI does.
• There's a lot of overhead when starting new
  processes on Win32 platforms, and DLL calls
  eliminate the need for new processes, thus
  reducing the running time.

37
Perl for ISAPI

• Perl for ISAPI (PerlIS), is an ISAPI extension
  that runs Perl scripts on Win32 platforms.
• Writing Perl scripts that run under PerlIS is not
  much different than writing scripts for the
  Common Gateway Interface (CGI).
• Perl for ISAPI doesn't have much general purpose
  use. For general purpose programming, stick with
  the perl interpreter (perl.exe).
• You may also see Perl for ISAPI referred to as
  PerlIS. PerlIS is the name of the Perl for ISAPI
  DLL.
• Perl for ISAPI is distributed as a part of the
  Perl for Win32 distribution

38
Configure IIS 3.0 or lower to support Perl for
Win32

• By default, Perl for Win32 maps the .plx
  extension to PerlIS?
• Consult Configuring and Testing a PERL sic
  Script with IIS
• Follow these steps
• Use Regedt32.exe to associate the extension in
  Registry for your scripts with the appropriate
  interpreter in the script map for IIS. This is
  under the Registry key HKEY_LOCAL_SYSTEM, with
  the sub-key System\CurrentControlSet\Services\W3S
  VC\Parameters\Script Map.
• Many people map two extensions one to perl.exe
  (for example, .pl) and another to PerlIS.dll (for
  example, .plx). Use the full paths to specify
  the executable files (perl.exe or PerlIS.dll) in
  the script map entry.

39
Windows NT Registry

• Registry is a unified database storing all
  hardware and software configuration information.

40
Use Regedt32.exe to update Registry

• Select Edit Add Value
• Enter .plx Click OK
• Enter full path as string value

41
Configure IIS to run Perl scripts

• Put your scripts in a virtual directory on the
  server that has Execute access but not Read
  access.
• add virtual directories or view their access with
  the Internet Service Manager. Remember that the
  URLs for your virtual directories can't overlap
  with URLs to directories in the WWW root
  directory.
• Ensure that your scripts are readable by the
  account used by the IIS server. You set this
  account in Internet Service Manager it is set to
  IUSR_your server name by default.
• Ensure that all supporting files, like the perl
  binary files, the perl library files, and the
  modules that you use, are all readable by the
  account used by the IIS server.

42
Configure IIS4.0 to Run Perl Scripts

• 1. Open the IIS 4.0 Internet Service Manager.
  This will bring up the Microsoft Management
  Console with the Internet Service Manager snap-in
  selected.
• 2. From the tree display on the left, select the
  level at which to apply the mappings. You can
  choose an entire server, web site, or a given
  virtual directory.
• 3. Select Properties from the Action menu.
• 4. If you chose to administer the properties for
  the entire server, the Server Properties dialog
  will appear. Select WWW Service from the Master
  Properties pull-down menu and click the Edit
  button under Master Properties. This opens WWW
  Service Master Properties. Select the Home
  Directory tab and proceed to step 7.
• 5. If you chose to administer the properties for
  an entire web site, the Web Site Properties sheet
  appears. Select the Home Directory tab and
  proceed to step 7.

43
Configure IIS4.0 to Run Perl Scripts

• 6. If you chose to administer the properties
  for a virtual directory, the Virtual Directory
  Properties sheet appears. Select the Virtual
  Directory tab and proceed to step 7.
• 7. Click the Configuration button. This opens
  the Application Configuration dialog.
• 8. Select the App Mappings tab and click the
  Add button. You see the Add/Edit Application
  Extension Mapping dialog.
• 9. To run Perl as a CGI application, type the
  full path to Perl.EXE followed by s s. When a
  script is executed, the first s will be replaced
  by the full path to the script, and the second s
  will be replaced by the script parameters.
• 10. To run Perl for ISAPI, type the full path to
  PerlIS.DLL. The s s is not required for ISAPI
  DLLs.
• 11. In the Extension field, type .pl or .plx (or
  whatever extension you want to use).
• 12. The application mapping is now complete.
  Click the OK button and click OK to dismiss any
  remaining dialogs/property sheets.
• 13. Close the IIS 4.0 Internet Service Manager.
