ASU product overview  
   

Features of the ASU software include

  • Windows NT Server Version 4.0 file, print, security, and management services on a system running the Tru64 UNIX Version 4.0F or higher operating system software.
  • Can participate in a Windows NT and Windows 2000 domain.
  • Can be configured as a primary domain controller (PDC), a backup domain controller (BDC), or a member server.
  • Can participate in a trust relationship.
  • Can participate in a TruCluster environment.
  • Provides two free client connections.
  • Provides Year 2000 support.
  • Supports international languages.

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 shares:

  • 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.

Users sharing files

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 download.

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.

Users sharing network printers

Network transport support

The ASU software provides and allows for the use of the following networking transport software:

  • 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 methods:

  • 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 configuration file.

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.

Security

The ASU software provides flexible security by supporting Windows NT exclusively, or Windows NT combined with Tru64 UNIX network security models.

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 accounts:

  • A domain user account that you create.  This account is used to authenticate Windows NT security.
  • 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.

Administration

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 shares
  • 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 dxprint).

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 supports.
