operating system software.

Sharing UNIX file systems
On a Tru64 UNIX system with ASU software
installed, you can make the following mounted
file systems available to Windows users as disk
- Advanced File System (AdvFS)
- UNIX File System (UFS)
- CD-ROM File System (CDFS), read only
- Network File System (NFS). The ASU
software automatically exports nonrestricted
network file systems as disk shares.
- Common Internet File System (CIFS)
ASU disk shares are based on Microsoft's LAN
Manager Extended Server Message Block (SMB)
protocols, which enable Windows users to connect
to them by using native Windows utilities, such
as the Windows Explorer. Once connected, the
file system that is associated with the disk
share appears as a transparent extension to a
user's local computing environment. For
example, using an application, such as Microsoft
Word, users can save files directly to the disk
share on the Tru64 UNIX server.
Other types of network users can access files
in ASU disk shares. For example, a Windows user
or a Tru64 UNIX interactive user can access a
text file stored in an ASU disk share.
Sharing Tru64 UNIX printers
You can make printers hosted by Tru64 UNIX
servers on which the ASU software is installed
available to Windows users as printer shares.
Users configure their Windows systems to use
ASU printer shares by using Windows utilities,
such as the Add Printer Wizard. The ASU software
stores supported printer drivers for Windows
clients in a disk share. The printer drivers are
then available for clients to automatically
Once configured, the printer that is associated
with the printer share appears as a transparent
extension to a user's local computing
environment. For example, using an
application, such as Microsoft Word, users can
print directly to the printer.
Network transport support
The ASU software provides and allows for the
use of the following networking transport
- NetBIOS for TCP/IP, which is used over the
system's installed TCP/IP transport software for
local and wide area networking.
- NetBEUI transport, which is used exclusively
for local area networking.
The ASU software can participate in a routed
wide-area TCP/IP network when you configure it
to resolve computer NetBIOS names and TCP/IP
addresses by using any or all of the following
- Microsoft WINS Server. You can configure
the ASU software as a WINS client.
- Domain Name Server (DNS).
- An lmhosts file. You edit the lmhosts file
on each system to add an entry that includes the
NetBIOS name and TCP/IP address for each system
with which the system needs to communicate.
Installation and configuration
You install the ASU software by using the Tru64
UNIX setld installation utility.
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
Registry value entries and lanman.ini
parameters are assigned default values, which
you can change.
See the Advanced Server
Installation and Administration guide
for more information about the ASU registry and
the lanman.ini file.
The ASU software provides flexible security by
supporting Windows NT exclusively, or Windows NT
combined with Tru64 UNIX network security
When using Windows NT exclusive security, only
the Windows NT file share level security
(including support for NT local and global
groups) and NT ACL permissions on individual
files are checked. UNIX user account and file
level security are ignored.
When using combined security, users have two
- A domain user account that you create. This
account is used to authenticate Windows NT
- A Tru64 UNIX user account. This account is
used to authenticate Tru64 UNIX security. By
default, when you create a domain user account,
the ASU server automatically creates a Tru64
UNIX user account in the local /etc/passwd file
or network information service (NIS) if an
account with the same name does not exist.
Alternatively, 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.
The ASU software runs the netlogon service,
which eliminates the need for the user to supply
a password for each disk or print share
connection that they make within a domain.
You can administer the ASU software from a
Windows system by using the following Windows
graphical user interfaces (GUIs):
- User Manager for Domains to create and
manage domain user accounts and groups
- Server Manager to create and manage disk
- Event Viewer to view ASU events
You can administer the ASU software from the
system running the ASU software by using the net
commands. If the system is running the
Tru64 UNIX Version 5.0 or higher software, you
can also administer the ASU software by
using the default Tru64 UNIX Motif-based GUI
tools (such as dxaccounts, dxfileshare, or
Tru64 UNIX TruCluster Software support
By using ASU and Tru64 UNIX TruCluster software
products, you can create a network environment
that continuously provides ASU services such as
disk shares, print shares, and PDC services if a
system running the ASU server stops.
International language support
You can configure the ASU software to display
disk and printer share names and ASU user and
group names in different languages. For
example, if Windows systems are running the
French edition of Windows, you can configure the
ASU software to display information in French.
The ASU software supports most of the languages
that the Tru64 UNIX operating system software
