Tutorial Descriptions
[Tutorial Overview] TUESDAY, OCTOBER 10, 2000 T1 Linux Systems Administration Bryan C. Andregg, Red Hat Software Who should attend: This tutorial is directed at System Administrators that are planning on implementing a Linux solution in a production environment. Course attendees should be familiar with the basics of systems administration in a UNIX(tm)/Linux(tm) environment: user level commands, administration commands and TCP/IP networking. The novice Administrator and the Guru should both leave the tutorial having learned something. From a single server to a network of workstations, the Linux environment can be a daunting task for administrators knowledged in other platforms. Starting with a single server and finishing with a multi-server 1000+ user environment, case studies will provide practical information for using Linux in the real world. The following areas will be covered with a special emphasis on security:
At the completion of the course attendees should feel confident in their ability to setup and maintain a secure and useful Linux network. The tutorial will be conducted in an open manner that allows for question and answer interruption. Bryan C. Andregg is the Director of Networks at Red Hat, Inc. He has been with the company for three years and in that time has moved from being the only Systems Administrator through almost every job in IS. Bryan is responsible for some horrible PERL and even worse shell which have made the lives of his replacements a nightmare. His job title on his next round of business cards will say "firefighter."
T2 Internet Security for Linux System Administrators
Who should attend: Linux/UNIX System Administrators, Network Managers, and Operations/Support Staff. The tutorial materials assume that the attendees have a good working knowledge of Linux/UNIX system administration, and are experienced Internet users. At this one-day tutorial you will learn strategies and techniques to help eliminate the threat of Internet intrusions and to improve the security of Linux/UNIX systems connected to the Internet. This tutorial will also help you understand, set up, and manage a number of Internet services appropriate to your site's mission. Topics include:
After completing the tutorial, attendees will be able to establish and maintain a secure Internet site that allows the benefits of Internet connectivity while protecting their organization's information. Ed DeHart is a former member of the CERT Coordination Center, which he helped found in 1988. The CERT was formed by the Defense Advanced Research Projects Agency (DARPA) to serve as a focal point for the computer security concerns of Internet users. Ed recently was the President of Pittsburgh OnLine, Inc., a successful Internet Service Provider that operated several UNIX and Linux servers. Currently, Ed is the President of Prism Servers, Inc. building Internet Firewalls.
T3 Inside the Linux Kernel
Who should attend: Application programmers and kernel developers. You should be reasonably familiar with C programming in the UNIX environment, but no prior experience with the UNIX or Linux kernel code is assumed. This tutorial will give you an introduction to the structure of the Linux kernel, the basic features it provides, and the most important algorithms it employs. The Linux kernel aims to achieve conformance with existing standards and compatibility with existing operating systems , however, it is not a reworking of existing UNIX kernel code. The Linux kernel was written from scratch to provide both standard and novel features, and takes advantage of the best practice of existing UNIX kernel designs. Although the material will focus on the release version of the Linux kernel (v 2.2), it will also address aspects of the development kernel codebase (v 2.3) where its substance differs from 2.2. It will not contain any detailed examination of the source code but will rather offer an overview and roadmap of the kernel's design and functionality. Topics include:
Stephen Tweedie works on Linux kernel internals and high availability for Red Hat, Inc. Before that he worked on VMS filesystem internals for Digital's Operating Systems Software Group. He has been contributing to Linux for a number of years, in particular designing some of the high-performance algorithms central to the ext2fs filesystem and the virtual memory code. Theodore Ts'o has been a Linux kernel developer since almost the very beginnings 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 architected and implemented Linux's tty layer. Outside of the kernel, he is also the maintainer of the e2fsck filesystem consistency checker. Theodore is currently employed by VA Linux Systems.
T4 Building Linux Applications
Who should attend: This class is designed for programmers who are familiar with the C programming language, the standard C library, and some basic ideas of UNIX shells: primarily pipes, I/O redirection, and job control. We will discuss (come prepared to ask questions) the major O/S related components of a Linux application and how they fit together. This course will prepare you to start building Linux applications. Since Linux is very similar to UNIX, you will be fundamentally prepared to build UNIX applications as well. The core of the tutorial will be an introduction to system programming: The process model, file I/O, file name and directory management, and signal processing lead the list. We will more briefly cover (in more or less depth depending on participant interest) ttys and pseudo ttys, time, random numbers, and simple networking. We will then cover some system library functionality, including globbing and regular expressions, command line parsing, and dynamic loading. If there is sufficient interest and time, we will then briefly survey the great variety of application programming libraries. Michael K. Johnson has worked with Linux since the first publicly released version. He is the co-author of "Linux Application Development" (Addison-Wesley, 1998) and is a software developer for Red Hat, Inc. Michael has written kernel, system, and application code for Linux, and has been teaching Linux courses and tutorials for six years. WEDNESDAY, OCTOBER 11, 2000 W1 Administering Linux in Production Environments Aeleen Frisch, Exponential Consulting Who should attend: This course is designed for both current Linux system administrators as well as administrators from sites considering converting to or adding Linux systems to their current computing resources. This course will cover configuring and managing Linux computer systems in production environments. We will be focusing on the administrative issues that arise when Linux systems are deployed to address a variety of real-world tasks and problems arising from both commercial and research and development contexts. Topics include:
Aeleen Frisch has been a system administrator for over 15 years. She currently looks after a very heterogeneous network of UNIX and Windows NT systems. She is the author of several books, including Essential Windows NT System Administration.
W2 Intrusion Detection and Network Forensics
Who should attend: Network and system managers, security managers, and auditors. This tutorial will assume some knowledge of TCP/IP networking and client/server computing. What can intrusion detection do for you? Intrusion detection systems are designed to alert network managers to the presence of unusual or possibly hostile events within the network. Once you've found traces of a hacker, what should you do? What kind of tools can you deploy to determine what happened, how they got in, and how to keep them out? This tutorial provides a highly technical overview of the state of intrusion detection software and the types of products that are available, as well as the basic principles to apply for building your own intrusion detection alarms. Methods of recording events during an intrusion are also covered. Topics include:
Marcus J. Ranum is CEO and founder of Network Flight Recorder, Inc. He is the principal author of several major Internet firewall products, including the DEC SEAL, the TIS Gauntlet, and the TIS Internet Firewall Toolkit. Marcus has been managing UNIX systems and network security for over 13 years, including configuring and managing whitehouse.gov. Marcus is a frequent lecturer and conference speaker on computer security topics.
W3 Designing Resilient Distributed Systems - High Availability
Who should attend: Beginning and intermediate UNIX system and network administrators, and UNIX developers concerned with building applications that can be deployed and managed in a highly resilient manner. A basic understanding of UNIX system programming, UNIX shell programming, and network environments is required. This course will explore procedures and techniques for designing, building and managing predictible, resilient UNIX-based systems in a distributed environment. Hardware redundancy, system redundancy, monitoring and verification techniques, network implications, system and application programming issues will all be addressed. We will discuss the trade-offs between cost, reliability and complexity. Topics include:
Evan Marcus is a Senior Systems Engineer and High Availability Specialist with VERITAS Software Corporation. Evan has more than 12 years of experience in UNIX Systems Administration. While working at Fusion Systems and OpenVision Software, Evan worked to bring the first High Availability software application for SunOS and Solaris to market. Evan has authored several articles and talks on the design of High Availability Systems. In February of 2000, Evan's first book, Blueprints for High Availability: Designing Resilient Distributed Systems, co-authored with Hal Stern of Sun Microsystems, was published by John Wiley and Sons.
W4 Network Administration
Who should attend: This tutorial is directed at System Administrators who are implementing Network Services and are looking for a background in the configuration of those services as well as basics of the protocols and performance tuning. Attendees should have used or been the client of an IP network before and have a basic knowledge of Systems Administration, but do not need to be experienced Network Administrators. Both new Network Administrators and Gurus will leave the tutorial having learned something. From a stand-alone client attached to the Internet to a distributed network of web servers, Systems Administrators are being tasked with bring their office environments on-line. The Network Services that need to be configured in order to this can be daunting to Administrators who aren't familiar with the applications required to do this. Configuration examples as well as brief overviews of the under-lying protocols will give the usable examples that work after the conference. Topics include:
At the completion of the course attendees should feel confident in their ability to setup and maintain secure Network Services. The tutorial will be conducted in an open manner that encourages question and answer interruption. Bryan C. Andregg is the Director of Networks at Red Hat, Inc. He has been with the company for three years and in that time has moved from being the only Systems Administrator through almost every job in IS. Bryan is responsible for some horrible PERL and even worse shell which have made the lives of his replacements a nightmare. His job title on his next round of business cards will say "firefighter."
