M1: Beginning Perl Programming for UNIX Programmers (Updated for Perl 5)
Tom Christiansen, Consultant

Who should attend: System administrators and toolsmiths, database managers, software test and support engineers, GUI and World Wide Web programmers unfamiliar with Perl or those with little programming experience. You should have a background in UNIX shell programming with a good working knowledge of regular expressions. A background in sed, awk, and/or C programming will prove useful.

What you will learn: Perl syntax and semantics. More importantly, you will learn how to read Perl (and thus learn from other peoples programming experiences).

Have you been spending a lot of time trying to solve problems in the shell or C? Perl is an extremely powerful and robust scripting language that can help you solve problems in less time. Now ten years old, Perl is the tool of choice because of its power, plus, it works on nearly every conceivable platform. Because it incorporates aspects of more than a dozen well-known UNIX tools, experienced UNIX users will come up to speed on Perl rapidly, and even programmers inexperienced at UNIX will learn UNIX through learning Perl.

You will learn about these topics: detailed descriptions and numerous examples of the syntax and semantics of the language; its data types and data structures; operators and control flow; regular expressions; I/O facilities; database access; user-defined functions; writing and using library modules; and an easy intro to Perls object-oriented programming mechanisms.

You will also hear about some of the new Perl 5 modules, including examples of full applications for Tk-based graphical programming, CGI programs, and client/server programming.

NOTE: This course is based on the current release of Perl (version 5.002,) but is not intended to be a detailed discourse on all advanced programming constructs of that release. It is a jump-start course on Perl for experienced UNIX programmers, not an advanced course for previous Perl programmers.

Tom Christiansen is a consultant specializing in Perl applications, optimizations, and training. He is a frequent instructor at USENIX and other conferences. He earned an MS degree in computer science from the University of Wisconsin at Madison.

M2: The Kerberos Approach to Network Security (Updated) Daniel Geer, Open Market, Inc., Jon A. Rochlis, BBN Planet

Who should attend:

What you will learn: the Kerberos network security system; how to start work on a computing environment that is both open and accountable, and be able to explain all this to your colleagues.

No matter what your position isdeveloper, system administrator, or managersecurity is one of the most urgent issues facing you today. In this course, you will learn how the Kerberos approach might solve the practical challenges of providing security for the cooperative electronic workplace, workplaces that aspire to location and scale independence in the client-server idiom or which need to provide the kind of security services that enable external access to enterprise data.

You will learn about these topics:

Above all, we will stress nuts-and-bolts of making this work in your environment, including administration and integration of this technology with your existing environments.

Daniel E. Geer, Jr. is director of engineering at Open Market, Inc. Formerly he was chief scientist, vice president of technology, and managing director of security consulting services for OpenVision Technologies. He is a consultant to major Wall Street financial institutions, and a frequent speaker at many technology conferences. He holds a Doctor of Science from Harvard.

Jon Rochlis is an engineering manager with BBN Planet where he leads groups developing managed connectivity and security services. Previously he was with OpenVision Technologies, responsible for systems and security management products.

M3: An Introduction to Java Ken Arnold, Sun Microsystems Labs.

Who should attend: Experienced programmers and technical contributors familiar with the C and C++ programming languages, the basics of object-oriented programming, and the basics of how the World Wide Web operates and is organized.

What you will learn: An understanding of the structure and features of the Java language.

No matter what your programming background is, programming in Java has become an important skill. Java is one of the most talked-about programming languages because it makes the Web interactive, rather than just a passive medium. Learn about Java and how it enables live content programming. This live content consists of full programs that can be placed into HTML documents. When such a document is loaded into a Java-enabled HTML viewer such as HotJava, the program is run, creating a page with active or even interactive elements.

You will also learn about Java features that allow you to write secure, robust programs that can be relied upon to run in a finite amount of space without crashing into a pile of bits. These features include garbage collection, exceptions, strong typing, and a clean separation between classes and interfaces. You will also examine the set of class and interface libraries which are defined as part of any compliant Java implementation.

You will find out how to create applets, programs that can be included as part of a standard HTML document, including how to write applets, what resources are available to them, and what features of the language and runtime environment allow these applets to be run securely by anyone on the Internet.

If time permits, the day will end in wild speculation and discussion of the possible technological and social impacts of the kind of computing that Java allows.

Ken Arnold is part of the team developing the JavaSoft Remote Messaging Interface for communication between Java code running on different machines. He is co-author, with James Gosling, ofThe Java Programming Language. He is a leading expert in object-oriented design and implementation, and has written extensively on C and C++ topics for UNIX Review, and is also co-author, with John Peyton, of A C Users Guide to ANSI C.

M4: Secure Java Programming (New)
Marianne Mueller and David Brownell, JavaSoft

Vincent C. Jones, PE

Who should attend: Technical individuals, regardless of title, who are responsible for the design and upkeep of extended LAN and LAN/WAN networks supporting multiple protocol architectures. A working knowledge of TCP/IP, Ethernet, and the OSI reference model is assumed.

What you will learn: Practical knowledge: how to benefit from emerging technologies without getting burnt and how to take advantage of mature technologies without getting locked in. You will gain an understanding of the theory behind the rules so you will know which rules must be strictly obeyed, which can be safely stretched, and under what conditions.

Technology is getting more complex every day, but how do you evaluate emerging technologies? In this course, you will gain an understanding of the theoretical underpinnings of modern network technology, probing the current limits of performance and distinguishing between those limits which are fundamental and those which are temporary. You will learn whats the hype and whats the reality on a wide range of critical technologies, from cell relay (ATM) and virtual LANs to IP version 6 and link state routing.

The bottom line is that every networking protocol and technology is a compromise among competing needs. The better you understand the underlying theory, the better able you are to make appropriate choices that best meet the needs of your users and their applications.

Topics include:

Vincent C. Jones is an independent consultant on network planning, design, and analysis of integrated local and wide area networks for cooperative, distributed processing in multivendor environments. Dr. Jones has over twenty five years of experience finding practical, cost-effective solutions to complex networking issues.

M9: System and Network Performance Tuning (New)

Who should attend: Novice and advanced UNIX system and network administrators, UNIX developers concerned about network performance impacts. You should have a basic understanding of the UNIX system facilities and network environments.

What you will learn: Procedures and techniques for tuning systems, networks, and application code.

More measurement and performance evaluation is being demanded of systems and networks than ever before. In this course you will learn about procedures and techniques for tuning systems, networks, and application code. Starting from the single system view, you will examine how the virtual memory system, the I/O system, and filesystem can be measured and optimized. The single host view will expand to include Network File System tuning and performance strategies.

A detailed treatment of networking performance problems, including network design and media choices, will lead to examples of network capacity planning. Youll learn about application issues, such as system call optimization, memory usage and monitoring, code profiling, real-time programming, and techniques for controlling response time. Many examples will be given, along with guidelines for capacity planning and customized monitoring, based on your workloads and traffic patterns.

Who should attend: Anyone responsible for running a Web site who wants to understand the tradeoffs in making it secure and how it is likely to be secured.

What you will learn: A comparison of available methods of Web security.

The World Wide Web is perhaps the most important enabler (so far) of electronic commerce. It has grabbed the popular imagination and the engineering and marketing efforts of a generation of on-line entrepreneurs and consumers. But it was initially designed with little thought to industrial strength security. Over the past several years numerous proposals have surfaced to secure the Web. This course will survey them with the goal of understanding the strengths and weaknesses of each.

The topics will include:

Daniel E. Geer, Jr. is director of engineering at Open Market, Inc.

Who should attend: People involved in the process of designing, implementing, evaluating, and managing the development of interactive graphical user interfaces. You need not have programming experience, but experience using interactive applications is required.

What you will learn: How to design a good user interface, and also how to constructively (and authoritatively) criticize a bad user interface.

With the advent of readily available, easy-to-use packages for building GUI-based systems, GUI-based systems have moved from the realm of specialty to almost mundane. But along with the widespread accessibility of GUI-builders has arisen a glut of poorly conceived user interfaces, which are hard to use, difficult to understand, or simply hard on the eyes.

You will get a broad introduction to user interface design and evaluation, introducing the task-centered interface design method, and covering principles behind UI design and techniques for UI evaluation. These techniques are pulled together at the end with a set of examples from visualization and Web page design.

Topics include:

You will learn why it is a very, very bad thing and how to criticize evil name-brand software effectively!

Joseph A. Konstan is an award-winning teacher and directs a research program in user interfaces and multimedia systems. He regularly teaches short courses on user interface design and evaluation at the University of Minnesota.

Who should attend: Webmasters and administrators charged with creating a World Wide Web service for their company. You should have some knowledge of UNIX system administration.

What you will learn: An in-depth understanding of your server environment and the critical issues surrounding ongoing maintenance.

The World Wide Web is the most widely used Internet service. Companies are quickly discovering that they need to be on the Web to provide information to customers and to keep up with the competition. This course describes how to set up and maintain a World Wide Web server on a UNIX platform. The servers covered in the course include the popular and freely-available Apache and NCSA Web servers.

Setting up the Web server is only half of the battle. Understanding exactly how the protocol works, what performance issues are critical, what the security implications are, and other nuances are just some of the important issues that all webmasters need to thoroughly understand.

Topics include:

Bryan Buus is the manager of XOR Network Engineerings Web services group. Prior to joining XOR, Bryan kickstarted OReilly & Associates' online efforts in 1992. He is a co-author ofManaging Internet Information Services, and has given seminars on managing Web services for CERFnet, the LISA Conference, and Hewlett Packard.

T7: Security for Software Developers: How to Write Code that Withstands Hostile Environments (New)
Marcus J. Ranum, V-ONE Corp.

T8: Solaris System Administration (New)
Marc Staveley, Consultant

Who should attend: System administrators who need to know the differences between SunOS 4.x and Solaris 2.x administration. Portions of this course will also be useful from a BSD to SysV.4 perspective. It will be most meaningful to system administrators who have some experience setting up and maintaining a network of SunOS 4.x workstations and servers.

What you will learn: New methods in Solaris to accomplish the same task as in SunOS (for example, the new NFS filesystem administration commands) and new features in Solaris (for example, the CacheFS filesystem). The course will concentrate on the Solaris 2.5 release.

Topics will include:

Marc Staveley has 14 years experience in UNIX application development and administration. An independent consultant, he is working with the Sun Microsystems Developer Support Centre assisting customers in migrating from SunOS to Solaris. He is a frequent speaker on the topics of standards-based development, multi-threaded programming, and system administration.

T9: IP version 6: An Introduction
Richard Stevens, Consultant

Who should attend: Network programmers and system administrators who will be converting applications and networks from IPv4 to IPv6, and implementors of IPv6. You should have a basic understanding of TCP/IP.

What you will learn: How to transition from IPv4 to IPv6 from the administration and programming standpoints.

Over the past few years, proposals have been made to replace IPv4 with a new version, mainly to overcome the addressing limitations of IPv4. In July 1994 the successor was chosen and named IPv6. Since that time numerous working groups have been busy completing the specifications for all facets of IPv6, and implementations are starting to appear. It is expected that vendor-supplied implementations of IPv6 will appear in the coming years and there will be a gradual transition of the Internet to IPv6.

You will get an overview of all aspects of IPv6, from the perspectives of a system administrator who needs to transition a network from pure-IPv4 hosts and routers to a mixture of IPv4 and IPv6 nodes and a programmer who needs to convert applications from IPv4 to IPv6 .

Topics include DNS support, new socket address structure, address conversion functions, transition mechanisms, automatic tunneling, header fields and extension headers, source routing, path MTU discovery, upper-layer issues, ICMPv6, multicasting, neighbor discovery, CIDR, anycasting, and mobility.

W. Richard Stevens is an independent consultant and author of the booksTCP/IP Illustrated, Advanced Programming in the UNIX Environment, andUNIX Network Programming.

T10: Writing Device Drivers Under Linux (New)
Theodore Tso, Massachusetts Institute of Technology

Who should attend: System programmers who need to write, modify, or maintain device drivers for the Linux operating system. You should know the C programming language. Some knowledge of general UNIX or Linux kernel design principals is desirable but not necessary.

Linux is becoming more and more popular, particularly because of the wide variety of device drivers which are available in the Linux kernel. You will learn about the several basic classes of Linux device drivers character devices, block devices, and network devices and the abstract device driver layers which simplify the task of writing tty devices and SCSI devices.

You will also hear about general kernel-level design and programming issues and the basic Linux kernel services needed by device drivers. Examples in the tutorial will be based on actual device drivers taken from the Linux 2.0 kernel and will include a tty-based device driver, a hard-disk device driver, and a Ethernet device driver.

Theodore Tso has been a Linux kernel developer since almost the very beginning of Linux. He implemented POSIX job control in the 0.10 Linux kernel. He is the maintainer and author for the Linux COM serial port driver, and the Comtrol Rocketport driver. He also architected and implemented Linuxs tty layer. Outside of the kernel, he is the maintainer of the e2fsck filesystem consistency checker. Theodore is the project manager for the Kerberos V5 development team at MIT. He participates in the Internet Engineering Task Force where he serves on the Security Area Directorate.

Wednesday-Friday, January 8-10, 1997



Opening Remarks: John Kohl, Pure Atria Corporation

Keynote Address: Developing on "Internet Time"
James Gosling, Sun Microsystems

The development of the WWW and its attendant phenomena have led to the notion of Internet Time in which things seem to just happen faster. To avoid running into the sorts of nonsense results expressed by people such as Fred Brooks in The Mythical Man Month, you cant simply work faster you have to change the way you work. One such change has been the development and deployment of the Java language and the write once, run anywhere applications it enables. Such technological developments are not usually, by themselves, sufficient to accomplish the necessary changes often the skills and knowledge of the people using the technology have to change as well. This talk will discuss the changes in practice and perspective that such technologies have required of those creating and using Java and its associated tools.

James Gosling is a vice president and Fellow at Sun Microsystems where he has been the lead engineer for the Java/HotJava system. He has built satellite data acquisition systems, a multiprocessor version of UNIX, several compilers, mail systems, and window managers. He has also built a WYSIWYG text editor, a constraint-based drawing editor, and a text editor called Emacs for UNIX systems. Early in his career at Sun, he was lead engineer of the NeWS window system. James Gosling received a PhD in Computer Science from Carnegie-Mellon University.

Charles E. Perkins, IBM T.J. Watson Research Center

Laptop computers and the growth of wireless communications are driving a push towards nomadic computing and mobile networking. This talk will cover recent protocol developments at the IETF in areas that directly affect nomadic users, including mobile-IP, service location, IPv6, dynamic host configuration protocol for IPv4 and IPv6, dynamic updates to DNS, and ad-hoc networking. Ill attempt the dangerous task of describing these protocol developments as part of a coherent whole and offer some ideas about the future evolution of mobile networking.

2:00-3:30: If Cryptography Is So Great, Why Isnt It Used More?
Matt Blaze, AT&T Research

By separating the security of information from the security of the media over which it is transmitted and stored, cryptographic techniques seem ideal for protecting data on widely decentralized networks or data stored in files on insecure PCs and workstations. Thats the theory, but in practice, cryptography is almost never available where it would be most useful. This talk will focus on some of the technical (rather than political) problems in integrating secure cryptography into real applications, operating systems, and networks.

4:00-5:00: The Inktomi Web Search Engine
Eric Brewer, University of California, Berkeley

With 54 million documents, HotBot is the most complete Web index online.


9:00-10:30: The AltaVista Web Search Engine
Louis Monier, Digital Equipment Corporation

AltaVista is the result of a research project started in the summer of 1995 at Digitals Research Laboratories in Palo Alto, California, that combined a fast Web crawler with scalable indexing software. Within three weeks of launch, the AltaVista site was handling over two million HTTP requests per day. By May 1996, the index had grown to more than 30,000,000 pages, and the site was receiving twelve million daily HTTP requests. This talk will describe the software and hardware technology behind this popular and successful Web search engine.

11:00-12:30: IPv6: The New Version of the Internet Protocol
Steve Deering, Xerox Palo Alto Research Center

A new version of the Internets core protocol, IP, has been developed by the Internet Engineering Task Force (IETF) and is now entering the IETF Standards track. The new IP, known as IPv6, is designed to meet the scaling requirements imposed by the explosive growth of the Internet, and to meet the demand for greater functionality at the Internet layer. This talk will include a brief review of the motivations and events that led to the development of IPv6, a description of how the new protocol differs from the current version, and a status report on the IPv6 specifications, implementations, and transition mechanisms.

2:00-3:30: Highlights from 1996 USENIX Conferences and Workshops

9:00-10:30: Measuring Computer Systems: How to Tell the Truth with Numbers
Margo Seltzer and Aaron Brown, Harvard University

"Benchmarks shape a field (for better or worse); they are how we determine the value of change." -David Patterson, 1994.

If benchmarks shape a field, then computer science is in bad shape. Our field is characterized by a few examples of excellent benchmarks, and a large number of poorly conceived measurements. We will examine the current practice in computer system measurement, citing both surpisingly good and embarrassingly bad real-world examples that illustrate common benchmarking pitfalls. Through this we will offer some benchmarking tips and guidelines.

11:00-12:30: Stupid Net Tricks
Bill Cheswick, Bell Laboratories

The Net (born c. 1992) is a new Thing. Is it a highway? A library? The old analogies dont work very well.

This new Place is a rich source of new experiments, new tricks, and new troubles. It is subject to clever and annoying hacking tricks, an arms race that the hackers seem to be winning at the moment. They are even putting the network infrastructure at risk, though benign administrative problems may well beat them to the punch. Netnews has evolved horizontal and vertical spamming and cancelbots. The Web offers new publishing opportunities. Marketers can game search engines by, for example salting their pages with extra keywords, causing an arms spiral with the engine designers. Now Javas designers would have us execute safe programs in unsafe containers. When all the security stupid tricks are fixed, denial-of-service attacks will remain.

2:00-3:30: Finding Bugs in Concurrent Programs
Gerard J. Holzmann, Bell Laboratories

In a concurrent system, machines can maliciously conspire to find loopholes in our otherwise perfect code, causing irreproducible forms of deadlock or failure to perform the desired function. Since software now controls just about everything of significance, it is important to discover these types of bugs well before the software is used.

SPIN is a popular verification system for concurrent software. In this talk Ill show how SPIN works, and give some examples of some of the more remarkable applications.




9:00-10:30: Linux: What It Is and Why It Is Significant

11:00-12:30 (Shared Session): The Pluggable Authentication Modules (PAM) Framework
Ted Tso, Massachusetts Institute of Technology

Authentication systems are constantly evolving, and it is important to shield the system administrator and application programmers from such changes. The Pluggable Authentication Module (PAM) framework allows a system administrator to dynamically change the authentication schemes used by programs such as login, ftpd and passwd. This talk will discuss how the PAM system uses dynamically linked shared libraries to provide plugability for the functions of system authentication and account, session, and password management.

2:00-3:30: Standards
