The Solaris PC NetLink Blueprint is quickly becoming the bible by which system administrators and system planners are obtaining the vital information they need to plan and implement an enterprise-capable PC NetLink Software system.
Solaris PC NetLink Software is the latest offering from Sun to enable Sun servers to support PC Client services. Solaris servers, with PC NetLink Software installed, not only support both the file and print services that are common to all Microsoft PC operating systems, but also allow Sun Workgroup and Enterprise servers to be fully integrated into NT Domains as a Primary, or Backup Domain Controller (PDC, BDC). In addition, PC NetLink Software offers the benefit of allowing NT system administrators to manage PC NetLink Software systems using the same tools they already use to set up and maintain NT servers.
The purpose of this book is to supply system planners and system administrators the information that allows them to install, tune, and use their PC NetLink Software to its maximum functionality and performance. Server sizing information is supplied for system planners to scale their PC NetLink Software to their own PC Client environment.

This book describes many aspects of the Solaris PC NetLink product from Sun Microsystems. This book is intended to help you gain a basic knowledge of the most common areas of the Solaris PC NetLink software functionality and provide best practices for its use.
The mission of the Sun BluePrints Program is to empower Sun customers with the technical knowledge required to implement reliable, available, extensible, and secure information systems within the data center using Sun products. The Sun BluePrints Program is managed by the Enterprise Engineering Group. This group provides a framework to identify, develop, and distribute best practices information that applies across the Sun product line. Technical subject matter experts in various areas contribute to the program and focus on the scope and usefulness of the information.
The Enterprise Engineering Group is the primary provider of the technical content of the Sun BluePrints Program that includes books, guides, and online articles. Through these vehicles, Sun can provide guidance, installation and implementation experiences, real-life scenarios, and late-breaking technical information.
The monthly electronic magazine, Sun BluePrints OnLine, is located on the Web at http://www.sun.com/blueprints
The book is aimed at two types of audiences:
This book is primarily written for experienced system administrators and planners who are familiar with UNIX, the Solaris operating environment, and Microsoft Windows NT.
System Administrators new to Solaris and to the PC NetLink software will find this book useful after they have gained a basic understanding of Solaris administration procedures.
This book does not replace the documentation supplied with the Solaris PC NetLink product. Instead, it supplies additional information such as software architecture, server scaling information, performance tuning tips, and best practices that are not generally available in the standard documentation.
This book was written during development and release of Solaris PC NetLink 1.0 and 1.1 software. For up-to-date information and announcements on new versions and capabilities of the PC NetLink software as it evolves, search the Sun web site at http://www.sun.com
for the term "PC NetLink."
After reading the description of the Solaris PC NetLink product in Chapter 1, you may recognize the description but associate it with a different product name. The Solaris PC NetLink product has been known by a variety of names during its development. First, the Solaris PC NetLink product is based on the AT&T Advanced Server for UNIX (AS/U) product. The AT&T product, in turn, was based on Microsoft Windows NT 4.0 source code. The AT&T product ships in various forms for different UNIX environments by several OEMs. When Sun acquired the code to start development, the internal project name was Project Cascade. The product's official name used for the first release of the product was SunLink Server.
The product name was immediately changed to Solaris PC NetLink. Unfortunately, time-to-market issues forced the first versions of the product to ship with the older name, SunLink Server. If you have one of the first versions of Solaris PC NetLink, your product probably is labeled, documented, and implemented in code as SunLink Server. That name still appears in the code and the man pages. Thus, Cascade Project, Sunlink Server, and Solaris PC NetLink all refer to the same product.
Throughout the book the term "PC NetLink" is used in several contexts. The context of the term changes the meaning. Some of the most common uses of the term are:
Chapter 1 "Introduction to the PC NetLink Software," provides an overview of the Solaris PC NetLink product and describes its server functionality.
Chapter 2 "The PC NetLink Software Architecture" describes the architecture of the PC NetLink software as well as how it implements its services.
Chapter 3, "Tuning a Solaris System for use with the PC NetLink software" focuses on tuning a Solaris server to best support the PC NetLink software. Benchmarks are used to study how each server subsystem influences PC NetLink software.
Chapter 4 "PC NetLink Tuning Parameters," looks at tuning the server from a PC NetLink software perspective. PC NetLink Registry parameters that control performance are reviewed and procedures for changing and managing these parameters are described.
Chapter 5 "Sizing a Solaris PC NetLink Server," explains how to size a PC NetLink server. Using a methodology applied to specific examples, it takes you step by step through the sizing exercise. A spreadsheet tool, available on the Sun web site, helps summarize and implement sizing.
Chapter 6 "Transitioning to a PC NetLink Server," investigates issues in transitioning from Windows NT servers and other Solaris-based products that offer functionality similar to that of Solaris PC NetLink. This chapter also discusses UNIX and Windows NT user account maintenance.
Chapter 7 "Server Consolidation and Resource Management," investigates how consolidating the services of several servers onto one larger, scalable system that supports multiple services solve system administration and server room requirements.
Chapter 8 "Monitoring the Resources Used by PC NetLink Software," reviews the Solaris commands to monitor system usage. This chapter focuses on tracking resources consumed by the PC NetLink software. The chapter includes scripts to help resolve resource consumption problems by specific users or clients.
Chapter 9 "Printing With PC NetLink," provides procedures for setting up and maintaining printer services with the Solaris PC NetLink product. It highlights issues to be aware of when printing using the PC NetLink software with the different Solaris releases.
Chapter 10 "PC NetLink Setup Maintenance and Troubleshooting Procedures," provides procedures for backing up user data and the databases used by the PC NetLink software. Procedures for setting up Directory Replication, Roaming Profiles, combining UNIX and Windows NT permissions, and other PC NetLink services are also provided.
Appendix A "File Service Benchmark Methodology," explains how the benchmarks are used to support sizing discussed in Chapter 5. It also defines the client, server, and network environment used to execute the Ziff-Davis NetBench benchmark.
Appendix B "A Profile of an Average End User," profiles the end user that the sizing example presented in Chapter 5 was based on.
Appendix C "Man Pages and Help Files," provides the text of all the UNIX man pages that were supplied by the Solaris PC NetLink product. Useful help files for the NET command are also listed.
The Solaris PC NetLink product ships with several online manuals. The manuals are available in HTML, PDF, and AnswerBook2 formats:
When installation is completed, these sources of information are available to administrators:
file:/opt/lanman/shares/admindoc/TOC.htm
file://servername/admindoc/toc.htm
where servername is the name of a PC NetLink server.hostname% /opt/lanman/sbin/slsmgr &
