This manual describes how to configure and manage the network interfaces and network services, and solve problems that might arise on systems running the Tru64TM UNIX (formerly DIGITAL UNIX) operating system software.
This manual assumes that the operating system software and the appropriate
networking subsets are installed.
Audience
This manual is intended for system and network adminstrators responsible
for configuring and managing network services.
Administrators are expected
to have knowledge of operating system concepts, commands, and configuration.
It is also helpful to have knowledge of Transmission Control Protocol/Internet
Protocol (TCP/IP) networking concepts and network configuration; this manual
is not a TCP/IP networking tutorial.
New and Changed Features
This manual has been revised to include the following:
An expanded overview of administrative methods
A new chapter on Internet Protocol Version 6 (IPv6), originally part of the Guide to Tru64 UNIX IPv6, a new section on configuring an IPv6 Domain Name System (DNS) master server, and updated sections throughout the manual to discuss where IPv6 is supported
New sections on configuring authentication of DNS dynamic updates and zone transfers
New and updated sections about automatically and transparently mounting remote file systems with the AutoFS daemon
An updated section on IMAP mail to discuss changes related to its directory structure
An updated section on administering and distributing alias information that describes new Sendmail support for LDAP servers
Updated sections throughout the manual on how to use the SysMan Menu to configure network components
Updated sections on problem solving tools
Information that was previously included in the Release Notes
This manual is divided into two parts and several appendices. Part 1, Chapters 1-14, contains management information and Part 2, Chapters 15-18, contains problem solving information. The appendices contain supplemental information.

Request for Comments (RFC)
Many sections of this book refer to RFCs (for example, RFC 1577) for more information about certain networking topics. These documents publicize Internet Standards, new research concepts, and status memos about the internet. You can access the full range of RFC documents and more information about the Internet Engineering Task Force (IETF) at the following URL:
Best Practices
Compaq Tru64 UNIX Best Practices describe additional concepts and tasks, for networking as well as other topics. You can find these documents at the following URL:

Icons on Tru64 UNIX Printed Books
The printed version of the Tru64 UNIX documentation uses letter icons on the spines of the books to help specific audiences quickly find the books that meet their needs. (You can order the printed documentation from Compaq.) The following list describes this convention:
| G | Books for general users |
| S | Books for system and network administrators |
| P | Books for programmers |
| D | Books for device driver writers |
| R | Books for reference page users |
Some books in the documentation help meet the needs of several audiences. For example, the information in some system books is also used by programmers. Keep this in mind when searching for information on specific topics.
The
Documentation Overview
provides
information on all of the books in the Tru64 UNIX documentation set.
