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.
Can I try the ASU software?
A. Yes! Included with the
ASU software are two complimentary connects.

Where is the ASU software?
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
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.
How do I purchase ASU license PAKs?
A. You can purchase ASDU-CONNECT PAKs
HP sales representative or authorized
The following table lists the quantities and
part numbers for ASDU-CONNECT PAKs:
What do I do after I have ASU license PAKs?
A. When you have the ASDU-CONNECT PAK,
- Load the PAK into the License Management
- Install and configure the ASU software.
See the ASU
Concepts and Planning, and
Installation and Administration guides for
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.
How do I configure the ASU
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.
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
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
How does the ASU software
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:
- Windows NT share level security
- Windows NT File System (NTFS) security
- Standard UNIX file and directory security
You can configure the ASU software to only use
Windows NT security.
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
- 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.
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
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
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
- Add Printer Wizard to create and manage
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.
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.
