Dear System Administrator:
Every year, systems multiply and networks become more complex. You are expected to be at the forefront of technology and manage this increasing complexity while keeping critical functions operating at peak performance. At the 10th LISA Conference, you can join your community and meet with other system administrators to find new strategies for ongoing and new support issues. This year's program will benefit you whether you are a novice or senior-level guru, network admin, or even the manager of these unique individuals.
No matter what your current issues are, you will be able to find a tutorial, paper, or talk that will address your needs. LISA '96 will include 35 tutorials, almost twice as many as in the past and many of them new; 29 peer-reviewed technical presentations; ten invited talks, and the ever-popular Birds-of-a-Feather and Guru Is In sessions. A Works-in-progress session will present the very latest solutions being developed. If you are very experienced, you may want to attend the Advanced Topics Workshop.
The Vendor Exhibition will include many products that vendors hope will allow you to work more efficiently.
LISA is a conference developed by system administrators for system administrators. We understand your concerns and are positive that this year's conference will be worth your time to attend!
Please join us in Chicago from September 29 to October 4. We hope to see you there.
Sincerely,

SUNDAY - TUESDAY, SEPTEMBER 29-OCTOBER 1, 1996
S1: Joining the Internet Safely Using UNIX and Firewalls
(9:00am - 5:00pm)
Tina Darmohray, Consultant
Intended audience: Participants should be familiar with basic
Internet concepts such as Internet services, TCP/IP, and
routing.
Connecting to the Internet is an exciting event for every organization but the security implications can often bring hesitation. This practical course outlines details and examples of UNIX network security and Internet connectivity issues. Site policies and topologies that implement them will be covered, including packet-filtering, application-level, and circuit-level gateways. Overviews of current, publically-available solutions will be provided, focusing on complete examples for configuring an Internet firewall. Prerequisites for this course are a knowledge of TCP/IP, DNS, and Sendmail.
This course will cover:
This course provides an introduction to the basic tools and concepts required to successfully administer a UNIX system. It utilizes a step-by-step approach to teach the commands and techniques required to maintain a well-running system, and to diagnose and solve problems.
Topics include:
Both BSD (SunOS 4.1.X) and SysV (Solaris 2.X) versions of UNIX will be discussed in detail, along with examples from Irix, Digital UNIX and Ultrix.
This course will explore procedures and techniques for tuning systems, networks, and application code. Starting from the single system view, it 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.
Detailed treatment of networking performance problems will lead to examples of network capacity planning. Application issues will be addressed. Many examples will be given, along with guidelines for capacity planning and customized monitoring based of your workloads and traffic patterns.
Topics include:
This course explains how to use Expect to automate interactive programs such as telnet, ftp, passwd, rlogin and hundreds of other applications.
It will cover how to test and connect interactive applications with no changes to the underlying programs or access to the original source - a common problem for legacy applications or sites without source code - but of value even with source code.
The course will demonstrate how to wrap interactive programs with Motif-like front-ends using Tk to control applications by buttons, scrollbars, and other graphic elements. Participants will learn to reuse interactive programs in Web applications without rewriting existing code.
Both total and partial automation will be covered, showing how
to automate and move interactive tasks into the background with
security and reliability.
This course is an introduction to HTML focusing on its basic properties, Web page design and creation.
Topics include:
Participants will know how to create and maintain Web pages many the tricks of the trade used by experienced HTML authors.
Two of the weakest security links in nearly any network are the network's user accounts and the administration tools used to maintain machines. This course will explain how install and deploy Kerberos to secure common system administration tasks and user access to workstations and time-sharing systems. The nuts-and-bolts details of running the system, rather than the cryptographic theory behind its operation, will be stressed.
Topics include:
The course will also include a discussion of freely and commercially available Kerberos products.
This course will teach you how to install a new name server or to maintain an existing one.
Topics include:
After completing this course, participants will be qualified to act as "hostmaster" for their sites, to allocate host names and addresses, to determine an appropriate subdomain naming convention, and to design and implement a server topology.
This course is a continuation of the Introduction to HTML, but stands on its own for those with a basic understanding of HTML. It explores some of the more complex HTML formatting tags and techniques.
Topics include:
After completing this course, participants will understand how to use advanced HTML features to create interesting, well-flowing HTML documents.
This course will focus solely on legal issues of importance to system administrators.
The law as it applies to the electronic media is not always intuitive or obvious. It is especially confusing and unpredictable as it pertains to computer and network system administration. This course provides invaluable information when you or one of your users is confronted with legal issues.
Topics will include the most recent legal developments:
The course will offer specific recommendations about what you can do to minimize your legal liability and clarify the limits of your responsibilities to your employer and other concerned parties.
A companion course on Obscenity, Indecency and the Communications Decency Act is offered on Monday.
This course will survey the DNS protocol and describe upcoming extensions to it, as well as implementation considerations in BIND.
Topics will include:
After completing this course, participants will know what the IETF has been up to and what to expect in upcoming BIND releases.
M1: NIS+ (9:00am-5:00pm)
Marc Staveley, Consultant
Intended audience: System administrators and technical managers
who wish to evaluate or set up an NIS+ network; those with some
experience setting up and maintaining an NIS (formally yellow pages)
or DNS system.
This course will examine why and how to set up and administer an NIS+ network. There will also be an overview of what NIS+ is and how it differs from NIS.
The course will cover the benefits of NIS+: its integration with DNS, enhanced security, cross-domain and cross-subnet operability, distributed network information, and dynamic binding. Basic concepts such as NIS+ tables, the namespace, and basic will be explained.
Topics include:
Network crisis case studies provide important insights into real-world network problems. We've chosen network and security crises to dissect and correct in front of your eyes.
IPv6 - What will 128-bit IP addresses mean to your site? What features and motivations should you consider when planning your network for the future? We'll give an overview of the IPv6 standard and explain how it relates to your existing environment.
Advanced Routing Protocols - The days of RIP as a useful routing protocol are numbered. As internetworks scale rapidly, you have to look towards protocols such as BGP and OSPF for reliable connectivity. We'll cover the basics of the protocols and explain their use in real-world environments.
Security Auditing 101 - So, you've done everything the experts recommend and more to secure your site. Now, how do you measure how secure your site really is? We'll take you through the anatomy of a security audit from start to finish.
Network Monitoring - Bigger networks need bigger management tools. Until recently, automated network monitoring was implemented as a mish-mash of home grown tools at most sites. Now there are a number of "production" quality tools available both commercially and from the net. We'll explain what a number of these tools do and compare them.
Server Performance - Years ago, sinking more money into a bigger CPU was often the fix for performance problems. With CPUs outperforming many other aspects of machines today, performance problems most often appear in areas such as network bandwidth, software optimization, memory usage, and system configuration. Learn how to tune your modern UNIX box to get the most bang for your buck.
The current underlying protocol used by TCP/IP applications and the Internet is called "IP version 4" (IPv4). Over the past few years, proposals have been made to replace it with a new version to overcome the addressing limitations. In July 1994 a successor was chosen, IPv6. Since then, numerous working groups have been completing the specifications for all facets of IPv6 and implementations are starting to appear. It is expected that there will be a gradual transition of the Internet to IPv6.
This course is an overview of all aspects of IPv6. It approaches 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:
Nearly ten years old now, Perl is a robust tool that is the language of choice for systems administrators and toolsmiths, database managers, software test and support engineers, GUI programmers, and World Wide Web programmers. Running on nearly every conceivable platform, Perl is an extremely powerful scripting language for problems previously solved at great effort in the shell or C. 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.
Topics include: 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 Perl's object-oriented programming mechanisms. The course will end with a tour of some of the new Perl5 modules includes examples of full applications for Tk-based graphical programming, CGI programs, and client/server programming.
Note: While this course is based on the current release of Perl, version 5.002, it is not intended to be a detailed discourse on all advanced programming constructs now afforded by that release. It is a jump-start course on Perl for experienced UNIX programmers, not an advanced course for previous Perl programmers.
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 security implications are and other nuances are just some of the important issues that all webmasters need to thoroughly understand. After completing this course, participants should have an in-depth understanding of their server environment and the critical issues surrounding ongoing maintenance.
Topics include:
This course will cover essential IP network adminstration, and background knowledge necessary to carry out such administration.
The course will begin with the Internet Model and some basics such as numerical addresses and the fundamentally important protocols: IP, ICMP, UDP, TCP, ARP, RARP. Packet routing (including subnetting) will be included, along with information about the most common UNIX routing daemons, routed and gated. This course will also take a brief look at the domain name system (DNS). Management of the common UNIX network services (telnet, rlogin, etc.) will be examined, along with the primary network service provider daemon, inet. Management of essential RPC services (NIS, NFS, mountd) will be covered as time permits. The course will finish with a section on troubleshooting and information on Internet resources.
This course will bring system administrators up to date on their responsibilities for dealing with adult-oriented content on their systems. If the Supreme Court affirms the lower court's rejection of the Communications Decency Act, this course will focus on the other laws which restrict the transmission of obscene and indecent content. If the Supreme Court overturns the lower court and reinstates the CDA, it will focus on the CDA itself and its implications. In either event, attendees will understand the current status of the law and how it affects them.
This course will include specific recommendations about how system administrators can reduce their exposure to liability, clarify their job responsibilities and be more effective in dealing with questionable content.
Communication involves not only the speaker and listener, but also their beliefs, pre-conceptions, and roles within the work environment. The different requirements and contexts in technical work and business/managerial work create barriers to understanding. These barriers can place limits on your personal growth as well as on your company's. If you cannot communicate effectively with your manager or your customers, you may lose their trust and recognition. This course will point out the problems in communicating effectively with non-peers, and help you remedy those problems.
Topics include:
This course will focus on real-world problems and configuring solutions, rather than Sendmail design and programming. It is designed to give network administrators an introduction to configuring Sendmail. It will cover the basics of the sendmail.cf file so you can define macros, use DNS MX records, understand rules and rulesets, and rewrite headers. It will then examine ways to:
This course provides an introduction to JavaScript.
Topics include:
While the focus of the course is client JavaScript, much of the information will be applicable to Netscape's LiveWire product. After completing this course, participants will be able to apply JavaScript to enhance the interactivity of their Web pages.
Meetings are a fact of life, and larger, more complex projects often involve larger, more complex meetings. Often we wonder "why was that meeting necessary?" A good meeting is necessary, timely, concise, and purposeful. Learn strategies to improve the quality of your meetings, whether you are hosting or attending them.
Topics include:
Sendmail 8.8, the latest release of Berkeley sendmail, has many new features. In many cases mail administrators can just compile the new release of Sendmail and use their old configuration files, but there are many new capabilities that "power users" may wish to utilize. This course discusses the new features in version 8.8 of Sendmail.
Topics include:
This course will also discuss two important features added in 8.7:
Time permitting, musings on the future direction of sendmail will be indulged in.
This course probes the issues of establishing a dedicated full-time connection to the Internet. A dedicated Internet connection is essential for a wide-area network (WAN) connection to an external environment. This course will cover the issues in choosing a WAN technology and implementation, choosing an Internet Service Provider (ISP), how your internal network may need to adapt, and how to effect the transition seamlessly. It will provide an overview of future WAN technologies.
Topics include:
Sendmail is arguably the most successful UNIX-based mail transfer agent in the world today. However, it has a reputation for being difficult to configure and manage. After introducing a bit of the philosophy and history underlying sendmail.
Topics will include:
This course describes the latest release of Sendmail from Berkeley, version 8.8. (Version 8 or variants thereon is currently shipped or will shortly be shipped by BSDI, Convex, Hewlett-Packard, Sequent, Silicon Graphics, and Sun.) Version 8 includes many of the popular features of IDA Sendmail.
This course teaches practical strategies and techniques to combat the threat of intrusions and improve the security of operating systems connected to the Internet. Participants are mandated to provide trustworthy network services. They need to understand security issues, and how to protect their systems on the Internet.
The course will cover fundamental security practices for UNIX system administration. Participants will learn about the latest information on security problems, defensive and offensive strategies, network security, and establishing appropriate site security policy.
After this course, participants will be able to establish and maintain a secure Internet site while protecting the organization's data. Participants will gain familiarity with security tools.
Topics include:
Video Conferencing on the Desktop - Ever participated in a video conference at your desktop? You will, and probably sooner than you think. Exciting new desktop video conferencing tools are available today. Learn how to setup software and hold private conferences, as well as join in to technical sessions at conferences like USENIX and IETF from afar.
System Administration Power Tools - Often, system administrators are caught saying "if only I had time to learn how to use that nifty new program." Unfortunately, system administrators usually do so much firefighting that they don't have time to stop and smell the new administration tools. In this overview of readily-available UNIX system administration power tools, we'll discuss packages that are we'll discuss packages that are likely to save you time and increase your salary.
Intro to expect - Perhaps the greatest sysadmin tool to come along since Perl, expect is a high-powered interpreted dialogue language which can act like your hands on the keyboard to perform tricky tasks while you're away, asleep or at play. We'll talk about the basic contructs of the language and write some sample programs.
The Network Crisis Case Studies: At the request of former students, we've put together a set of network problem case studies that will be dissected and corrected in front of your eyes using many tools available on your UNIX system or from the net.
Policy and Politics - Many of the policies and procedures followed at a site are carefully filed in the sysadmin's head. With the worldwide net invading your local site, this folklore needs to be written down, run past lawyers, and followed by your sysadmin staff. We will discuss approaches to these tasks, both good and bad, and illustrate with war stories, sample policy agreements, and procedure checklists.
This course will be split between describing 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:
This course discusses CGI and other WWW programming using Perl with special attention to system security issues. All aspects of writing and processing fill-out forms are covered using the standard CGI.pm module. Some attention is also given to parsing of HTML documents and writing "spiderbots", automata that navigate the Web on their own.i
Topics include:
The World Wide Web is perhaps the most important enabler 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 design with little thought to industrial strength security. Numerous proposals have surfaced to secure the Web. This course will survey them with the goal of understanding the strengths and weaknesses of each.
Topics include:
The use of Sun's Network Information Service (formerly yellow pages) has become widespread for providing common configurations across a network of workstations. However, NIS out of the box is very much like a wild tiger: dangerous and unpredictable. This course will teach you how to tame the tiger and adapt NIS for effective use in a UNIX network. It discusses NIS's strengths and mechanisms for working around its weaknesses.
The course starts with the basics of NIS configuration and operation, covers details of the information NIS can provide, effective use of netgroups, adding additional maps, management of slave servers, available utilities for maintenance, security and performance concerns, and interaction with DNS. It ends with a frank discussion of NIS's shortcomings and the implementation of possible alternatives to NIS.
It should be noted that although the successor to NIS, NIS+, provides similar functionality to NIS, the commands and techniques for managing the two systems are completely different and the knowledge and experience is not transferable.
This course covers the basic installation and management of a netnews server using INN.
Topics include:
After completing this course, participants will be able to create and maintain INN server hosts, including reader support, transport ("netnews peering") administration, and installation of source code patches to INN.

Participants given a workbook with step-by-step instructions for all material covered. Using the workbook and the material presented, participants will have the tools to administer new and existing MS Windows NT networks, including:
The network is down: how do you fix it? This course focuses on a practical problem-solving method, using a diagnostic decision logic table (DDLT) developed by the instructor, based on many years' experience. The DDLT gives step-by-step instructions on what to look at, what it should look like, and how to fix it. Even if it's not your job to fix it, you can help your network administrator by being able to gather vital statistics about the network.
The course focuses on specific examples of network failures, and introduces and amplifies on TCP/IP and Ethernet concepts along the way. Examples are taken from SunOS 4.x and Solaris 2 UNIX systems, but apply in principle to any TCP/IP network.
After this course, participants will be able to follow the DDLT to isolate, diagnose, and correct common failures inTCP/IP networks.
Topics include:
This course will generally survey the NNTP and NNRP protocols, with special attention to reader vs. transport verbs and to the performance implications of "offline news servers" and Netscape Navigator. Obscure INN performance tuning issues will be covered, as will advanced troubleshooting and debugging techniques.
Topics include:
After completing this course, participants will know how to diagnose serious but less obvious configuration or utilization problems, and will be able to make informed decisions about complex enterprise-wide netnews topology.

Three panelists argue the question from three angles: keep formal POSIX-type standards, use proprietary standards, or abolish standards altogether.
The Web is the bane and the boon of system administrators. While it is reasonably easy to configure a small web site and maintain it, dealing with a popular one is another story altogether. Sites like Galt, Lycos, and Yahoo regularly receive millions of hits per day, most of which are CGI scripts.
Even if your site isn't a universally-used site like these, a user with a popular set of pages can bring your server to its knees. This talk will address some of the issues of web server scaling from the perspective of a timeline of learning experiences, and will discuss such issues as name service, logging, network loads, system and server configuration, etc.
This talk will provide the reasoning and history behind his site's decision to implement our campus backbone network as an ATM fabric. By describing the advantages and disadvantages of the various options (Switched Ethernet, FDDI and ATM) that were considered and the demands for bandwidth both on campus and in the wide area that is foreseen, this presentation will help you decide if ATM is an appropriate technology for your site.

Nortel Ottawa has a fairly large site, 10,000+ nodes, and a rather large worldwide network of 120,000+ nodes. Effectively managing a network like this requires an accurate assessment of what services should be centralized and what tasks should be distributed to local administrators. The goal is to provide enough flexibility such that anarchy and entropy do not take over the network, and to keep services and service levels the same throughout the network. The speaker discusses how that goal was accomplished.
Following on the heels of a very successful BOF and BayLISA talk, Stokely and Darmohray present insights and information for people who plan on, or already have, set out on their own. Contracts, taxes, billing, getting work, and much more will be discussed, and a lively question-and-answer session is planned.
This talk will take a fascinating look behind the scenes of one of the Internet's richest and most popular free access archive sites, sunsite.doc.ic.ac.uk. This busy site is powered by an 8-way Gbyte SS1000 with some 70+GB trans (logged) RAID5 disk space, Ethernet and FDDI networking (expect ATM and switching shortly). Efforts to improve network and server performance, along with unburdening the campus network of server-bound traffic, will also be discussed.

While the future of any technology or technological aspect of our society is difficult to predict, examining the past can lead to an enlightened view of the future. This talk highlights certain events from the last decade and uses them as a framework to analyze the hype, financial and economic factors, political factors, technical issues, cultural issues, and wildcards that will affect system administration in the future.
Managing large numbers of UNIX userids in an enterprise wide system can be approached as a problem of managing information about people. This talk will look at some of the problems and opportunities encountered in implementing Simon (similar to MIT's Moira). Rather than discussing the gritty technical details, the talk looks at problems and techniques in dealing with multiple data feeds, maintaining information security, understanding (and developing) information policy, and some of the problems encountered in merging and transforming this information. We will also look beyond the maintenance of UNIX userids.
With stories of computer crime regularly in the news, we are painfully aware that our computer systems are vulnerable. While we would prefer to design and manage our systems to prevent attacks, technical, operational, and practical limitation conspire against us. Intrusion detection detects the attacks which do occur and provides an opportunity to respond to them in a timely fashion. This talk will present both an historical and technical overview of the field of intrusion detection. The history of intrusion detection provides insight into which approaches have and have not worked, reflects the changing threats over the years, and may provide clues as to the future of intrusion detection.
This talk will describe how the speaker became a felon in the process of doing his job as a system administrator in the well-publicized Oregon v. Schwartz case (victim: Intel). It will include some points about Oregon's current law and the implications of this case on the computer community. Similarly broad laws appear on the books in other states. There will be a special focus on how to make sure this doesn't happen to you.

** The Bismark is not in walking distance from the Marriott, so
you may want to book here for the Saturday nights, and then at
another hotel closer to the Marriott for the Conference days.
Special Note:
The USENIX conferences place a heavy demand on meeting space. To
get meeting space and other services free and keep your conference
registration fees low, USENIX guarantees to use a number of
sleeping rooms. Contracts are signed long in advance. The penalty
for not meeting the guarantee may exceed $100,000. You must
mention USENIX when reserving your room to ensure that it counts
against our room guarantee. If you use a a corporate rate, it will
not count against our commitment.
