General questions

Q. What is ASU?

A. ASU is a Tru64 UNIX layered application that integrates Tru64 UNIX and Windows environments. The ASU software implements Windows NT Version 4.0 Server services and functionality on a system running the Tru64 UNIX Version 4.0F or higher operating system software. The Tru64 UNIX system on which ASU is running appears as a Windows NT Version 4.0 server to other Windows systems and to users of Windows systems.

You use  Windows commands and utilities to manage the ASU software and to make UNIX-based file systems and printers available to Windows users as shares. Windows users access the shares without modification to their software.

Q. Can I try the ASU software?

A. Yes!  Included with the ASU software are two complimentary connects. 

See Two Free Connects for more information

Q. Where is the ASU software?

A. .

Licensing questions

Q.How is ASU licensed?

A. ASU licenses are supplied in the form of a product authorization key (PAK) called ASDU-CONNECT. You load the ASDU-CONNECT PAK into the Tru64 UNIX License Management Facility (LMF).

ASDU-CONNECT PAKs are available in license quantities of 10, 25, 50, 100, 250, 500, and 1,000.  You purchase ASDU-CONNECT PAKs based on your needs. For example, if you expect 275 Windows users to access disk and printer shares, then you should purchase one PAK for 25 licenses and one PAK for 250 licenses.

One ASDU-CONNECT license is used by each Windows client that browses or first connects to a share on the Tru64 UNIX system on which the ASU software is running. The license allows the client to browse and connect to disk and printer shares offered by that ASU server. The client retains the license until it stops browsing and terminates its connections, at which time the license can be reassigned. A client uses an ASDU-CONNECT license from each ASU server to which it browses or connects.

Q. How do I purchase ASU license PAKs?

A. You can purchase ASDU-CONNECT PAKs from your HP sales representative or authorized  business partner

The following table lists the quantities and part numbers for ASDU-CONNECT PAKs:

Number of Concurrent Users ASDU-CONNECT PAKs
1 QL-5U29M-3B
10 QL-5U29M-3C
25 QL-5U29M-3D
50 QL-5U29M-3E
100 QL-5U29M-3F
250 QL-5U29M-3G
500 QL-5U29M-3H
1000 QL-5U29M 3J

Q.. What do I do after I have ASU license PAKs?

A. When you have the ASDU-CONNECT PAK, you must:

  1. Load the PAK into the License Management Facility (LMF).
  2. Install and configure the ASU software.

See the ASU Release Notes, Concepts and Planning, and Installation and Administration guides for more information.

Administrative questions

 Q. How do I install the ASU software?

A. The ASU software has mandatory and optional subsets. You use the I UNIX setld utility to install the ASU subsets.

After the installation you run a configuration utility to provide information that the ASU software requires to start.

Q. How do I configure the ASU software?

A. The ASU software is configured by values assigned to value entries stored in a central database, called the ASU registry, and by values assigned to parameters in the lanman.ini configuration file.

Registry value entries and lanman.ini parameters are assigned default values, which you can change.

See the ASU Installation and Administration guide  for more information about the ASU registry and the lanman.ini file.

Q. What is a disk share?

A. A disk share is a file system that is made available through the ASU software.   Windows users map a network drive to connect to the disk share.  If the user is granted access to the disk share, the disk share appears as a transparent extension to the user's local computing environment.

Q. What is a printer share?

A. A printer share is a network printer that is made available through the ASU software.   If the user is granted access to the printer share, the user can configure their system to use the printer share, which then becomes a transparent extension to the user's local computing environment.

Q. How does the ASU software implement security?

A. By default, Windows NT and Tru64 UNIX security policies are enforced when a Windows user requests access to a share. A Windows user must pass the following three levels of security before they can access a share:

  1. Windows NT share level security
  2. Windows NT File System (NTFS) security
  3. Standard UNIX file and directory security

You can configure the ASU software to only use Windows NT security.

Q. Do I have to create user accounts?

A. Yes. You must create a domain user account for each user. A domain user account is used to authenticate Windows NT security policies. If Tru64 UNIX security policies are enforced, users must also have one of the following accounts to  authenticate Tru64 UNIX security policies: 

  • A Tru64 UNIX user account located in the local /etc/passwd file or network information service (NIS). By default, when you create the domain user account, the ASU server will create a user account in the local /etc/passwd file or NIS if an account with the same name does not exist.
  • A user account on a Windows 2000 or Windows NT Server Version 4.0. You can configure the Tru64 UNIX operating system software to direct authentication requests to a Windows 2000 Server or to a Windows NT Server Version 4.0. The Windows 2000 Server or Windows NT Server Version 4.0 uses its user account information to authenticate users on behalf of the Tru64 UNIX system. This is useful if you store user account information on a Windows 2000 Server or on a Windows NT Server Version 4.0 and you do not want to store user account information on the Tru64 UNIX system. 

Q. What is a domain?

A. A domain is a group of ASU and Windows NT servers that share a central database that contains information about domain user accounts and groups of domain user accounts.  Servers sharing the database eliminates the need of users having accounts on each server.

Each domain includes one server that is configured as the primary domain controller (PDC), which maintains the master copy of the database, and usually one or more backup domain controllers (BDCs) to which the PDC replicates database changes. BDCs provide fault tolerance in case the PDC is unavailable and participates in user domain log in authentication. Once authenticated, users can access the disk and printer shares to which you have granted them access.

You can establish trust relationships between domains where the controllers in one domain trusts the authority of another domain's database.  Trust relationships expands users access to include the disk and printer shares that are offered by servers in the domains that are participating in the trust relationship. 

Q. Can I use Windows-based tools to manage the ASU software?

A. Yes, you use the:

  • Windows-based User Manager for Domains utility to create and manage domain user accounts and groups. 
  • Server Manager utility to create and manage domain user account and group access to disk shares. 
  • Add Printer Wizard to create and manage printer shares. 

Q. Can I manage ASU from UNIX?

A. Yes, you can administer the ASU software using net commands on a system running the Tru64 UNIX Version 4.0F or higher software on which the ASU software is installed.

You can also use the default Tru64 UNIX Motif-based GUI tools (such as dxaccounts, dxfileshare, or dxprint) on a system running the Tru64 UNIX Version 5.0 or higher software on which the ASU software is installed.

Q. How many client can connect to the ASU server?

A. Several thousand clients have connected to a single ASU server however, the answer to this question depends on the size of the server on which the ASU software is running and the amount of network activity between the clients and server.
