Full-Day Tutorials
S1 Computer Forensics NEW! Simson L. Garfinkel
Simson L. Garfinkel, Naval Postgraduate School

Who should attend: Anyone interested in forensics: recovering lost or deleted data, hunting for clues, and tracking information.

Computer forensics is the study of information stored in computer systems for the purpose of learning what happened to that computer at some point in the past—and for making a convincing argument about what was learned in a court of law. Today computer forensics covers four broad categories:

  • Hard drive forensics, which aims to inventory and locate information that is on a computer's hard drive, whether or not the information is visible to the computer's user. Hard drive forensics includes the recovery of deleted files and file fragments, the construction of timelines, and the creation of profiles of a computer's user.
  • Memory forensics, which analyzes the memory (or memory dump) of a computer system to reveal information about what the computer has been doing.
  • Network forensics, which captures and analyzes information moving over a computer network. Network forensics can be based on full-content analysis or the analysis of network flows.
  • Document forensics, in which specific files are analyzed for subtle and possibly hidden information. Document forensics can recover deleted information from Microsoft Word files or reveal which computers were used to create an individual file.

Take back to work:

  • Modern forensic tools, including both open source and commercial
  • Drill-down familiarity with disk forensics, including specific tools and techniques
  • The history of computer forensics (celebrated cases)

As a system administrator, you perform change management every day. Every time your finger hovers over the return key, that's risk management. Every time you apply a patch to your desktop before you apply it to production, that's change qualification. Every time you stay late to apply a patch out of hours, that's change scheduling. Although you may be doing it now, you have probably never considered the deeper aspects of what you do and how you might do it better.

Take back to work: A grasp of the many aspects of effective change management and how you can improve the process, using tactics, tools, and tips learned in this course.

Topics include:

  • The basic change management process
  • Building a change plan

Sunday Morning Half-Day Tutorials
S7 Time Management for System Administrators Tom Limoncelli
Tom Limoncelli, Google NYC

Who should attend: IT people, sysadmins, and other busy people who want to improve their time-management skills; those who want to have more control over their time and better follow-through on assignments.

If you agree with any of these statements, this class is for you:

  • I don't have enough time to get all my work done.
  • As a sysadmin, I can't schedule, prioritize, or plan my work.
  • I'm spending all my time mopping the floor; I don't have time to fix the leaking pipe.
  • My boss says I don't work hard enough, but I'm always working my ____ off!

Based on a new book from O'Reilly, this tutorial will help you get more done in less time.

Take back to work: The skills you need to streamline your workflow to make your users—and you!—happy.

Topics include:

  • Why typical "time management" books don't work for sysadmins.
  • What makes "to-do" lists fail, and how to make them work.
  • How not to forget a user's request ever again!
  • How to prioritize tasks so that users think you're a genius.

S8 Advanced DHCP (This Is Not Your Grandparents' DHCP) NEW! David Hankins
David Hankins, ISC

Who should attend: Anyone who is involved in administering a network and who still believes that DHCP is a simple protocol like ARP that you just turn on and forget. The protocol now includes (and ISC's reference implementation now provides) important tools to improve the security, reliability, administerability, and Sarbanes-Oxley auditability.

We are well aware that your parents' home router implements DHCP along with NAT, and that you've never had to change or even look at its configuration. But, unlike that home system, your enterprise network will be attacked, hacked, and audited, and it needs to keep working even during significant partitions and failures.

Take back to work: How to use DHCP to keep your networks secure and reliable.

Topics include:

  • How to make DHCP more reliable
    • Configuring, managing, and administering failover
  • How to have more flexible control over users (you are no longer limited to simple yes/no access control keyed on MAC address)

    • Conditional response
    • Client classing
    • Allocation by class
  • Using DHCP LEASEQUERY to find information about a lease using IP address, MAC address, or client identifier
  • How to integrate DHCP with Dynamic DNS (when your DHCP server allocates an address, you can make sure DNS knows about it immediately, without using the hack of giving pre-assigned DNS names to every address in your pools)
  • How to configure your DHCP server so that it does everything that VOIP phones need
  • Using the new RFC 3925 Vendor-Identifying Options

S12 Network Diagnosis and Improvement with Netflow NEW! Michael W. Lucas
Michael W. Lucas, Author and Consultant

Who should attend: Administrators who need more information about their networks.

Netflow is an extremely powerful network management tool with a reputation for being obtuse and expensive. While Netflow might not be easy, it becomes much simpler if someone takes you through it. Netflow picks up where tools like MRTG leave off, and will not only solve technical problems but resolve administrative and social problems you probably resigned yourself to enduring years ago.

Every network administrator has had a problem that can only be caught by a packet sniffer while it's happening. Netflow is a historical packet sniffer, giving you eyes into your network over a period of time. You know not only what is happening now, but what happened yesterday or last week.

With the right knowledge, anyone can implement Netflow for small costs in both hardware and time. I will present a coherent, start-to-finish solution that works in any vaguely modern environment and can be assembled out of a few gigs of disk, some network cards and cables, a free UNIX of choice, and freely available software, while also leveraging any Cisco hardware students already have. Attendees will be fully equipped to work with Netflow the day they return home.

S13 Implementing Some Autonomic Principles Using Cfengine NEW! Mark Burgess
Mark Burgess, Oslo University College

Who should attend: Anyone who likes to use simple tools well and with an understanding of their implications; anyone who wants to make the most of a tool that deals with long- and short-term management.

A lot of marketing and hype has been invested in the term autonomics lately, but what does this actually mean? Autonomics covers a number of ideas, most of which boil down to adding feedback loops into systems so that they can sense operational changes and respond automatically. This basic idea has been embodied in cfengine for many years.

Take back to work: A simple way to use cfengine to achieve the goals of autonomic management.

Topics include:

  • When and how does hands-free computer management make sense?
  • What mechanisms are there in cfengine for "self-adaptation"?
  • Key concepts of and obstacles to implementing hands-free administration
  • Self-healing
  • Fixed-point rules
  • Probabilistic management
  • Peer monitoring
  • Intermittency and reliability measures

Full-Day Tutorials
M1 Administering Linux in Production Environments Aeleen Frisch
Æleen Frisch, Exponential Consulting

Who should attend: Both current Linux system administrators and administrators from sites considering converting to Linux or adding Linux systems to their current computing resources.

Linux has graduated from being a "toy" operating system favored by hobbyists into a production-level operating system embraced by major corporations such as IBM, Novell, and Amazon. It is used on the front line for mission-critical applications, and mastery of this operating system is now becoming a major asset to system administrators.

Linux system administrators in production environments face many challenges: the inevitable skepticism about whether an open source operating system will perform as required; how well Linux systems will integrate with existing computing facilities; how to locate, install, and manage high-end features which the standard distributions may lack; and many more. Sometimes the hardest part of ensuring that the system meets production requirements is matching the best solution with the particular local need. This course is designed to give you a broad knowledge of production-worthy Linux capabilities, as well as where Linux currently falls short. The material in the course is all based on extensive experience with production systems.

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. This course is designed for both current Linux system administrators and for administrators from sites considering converting to Linux or adding Linux systems to their current computing resources.

Laptop requirements: Each student should have a laptop with wireless access for remote access into an instructor-provided Solaris 10 machine (if you do not have a laptop, we will make every effort to pair you with another student to work as a group). Your laptop does not need to be running Solaris.

Monday Morning Half-Day Tutorials
M6 Over the Edge System Administration, Volume 1 David N. Blank-Edelman
David N. Blank-Edelman, Northeastern University

Who should attend: Old-timers who think they've already seen it all, and those who want to develop inventive thinking early in their career. Join us and be prepared to be delighted, disgusted, and amazed. Most of all, be ready to enrich your network and system adminstration by learning to be different.

It's time to learn how to break the rules, abuse the tools, and generally turn your system administration knowledge inside out. This class is a cornucopia of ideas for creative ways to take the standard (and sometimes not-so-standard) system administration tools and techniques and use them in ways no one would expect. We'll also cover some tools you may have missed.

Note: The teacher takes no responsibility should your head explode during this class.

Take back to work: New approaches to old problems, along with some ways to solve the insolubles.

Topics include:

  • How to (ab)use perfectly good network transports by using them for purposes never dreamed of by their authors
  • How to increase user satisfaction during downtimes with 6 lines of Perl
  • How to improve your network services by intentionally throwing away data

M7 RRDtool as a Communication Tool NEW! Tobias Oetiker
Tobias Oetiker, Consultant and author of RRDTool

Who should attend: Scripters and programmers who would like to create a custom monitoring application with great presentation tools.

Over the past few years RRDtool has become the standard method for handling time-series data in the networking area. RRDtool takes care of all the work related to data storage and presentation. Many users only access RRDtool through some front-end application such as Cacti or Cricket.

In this tutorial you will learn how RRDtool works from a programmer's point of view and how you can use it to write your own custom monitoring applications. An emphasis will be put on presentation aspects. The best data is worth only as much as your bosses and customers understand of it, so the graphs you create are key components to any such application.

Strata Rose Chalup, Project Management Consultant

Who should attend: System administrators who want to stay hands-on as team leads or system architects and need a new set of skills with which to tackle bigger, more complex challenges. No previous experience with project management is required.

People who have been through traditional multi-day project management courses will be shocked, yet refreshed, by the practicality of our approach. To get the most out of this tutorial, participants should have some real-world project or complex task in mind for the lab sections.

This tutorial focuses on complementing your own organizational style (or lack thereof) with a toolbox of ways to organize and manage complex tasks without drowning in paperwork or clumsy, meeting-intensive methodologies. Also emphasized is how to bridge the gap between ad hoc methods and the kinds of tracking and reporting traditionally trained managers will understand.

Take back to work: A no-nonsense grounding in methods that work without adding significantly to one's workload. You will be able to take an arbitrarily daunting task and reduce it to a plan of attack that will be realistic, will lend itself to tracking, and will have functional, documented goals. You will be able to give succinct and useful feedback to management on overall project viability and timelines and easily deliver regular progress reports.

Topics include:

  • Quick basics of project management
    • The essentials you need to know

M9 How to Interview a System Administrator Adam Moskowitz
Adam Moskowitz, Menlo Computing

Who should attend: System administrators of all levels of experience, as well as managers of system administrators. The course will focus on techniques for interviewers, but even sysadmins who are just starting out will learn some things to use as an interviewee. Managers of system administrators and junior sysadmins will learn, among other things, how to interview someone who knows more than you do. Junior administrators will also learn how to respond (as an interviewee) when asked a bad question—in particular, how to turn it into a better question.

Do you know how to interview a system administrator? Do the questions you ask elicit specific, narrowly focused information, or do they show you both the depth and breadth of a candidate's knowledge of a particular subject or technology? Do you know how to distinguish between a candidate who is just trying to bluff through the interview and one who has some knowledge of the field but hasn't yet become an expert? Are trick questions ever appropriate, and, if so, when and why? Some questions shouldn't be asked, and some would even land you in hot water with your company's HR or legal department: do you know what those questions are? Finally, have you figured out how to help a candidate do well in an interview while still getting an objective and fair assesment of their skills?

If you answered "no" or even "I'm not sure" to any of these questions, this course is for you.

Take back to work: Increased confidence in your ability to weed out the posers and hire really great sysadmins.

Topics include:

  • Purposes of an interview
    • To assess the candidate's technical skills
    • To get a feel for the candidate's personality and interpersonal skills
    • To learn whether a candidate is likely to be a good fit with the company and with the IT group
    • To help the candidate figure out whether he wants this job and whether he is likely to do well in the position
    • Maybe even to teach the candidate something new about system administration
  • Basic questions to bear in mind
    • Is the candidate comfortable?
    • Does he need a drink or a bathroom break?
    • Does she know who you are and what your role in the company is?
  • Preparatory questions
    • What are you really trying to learn about the candidate's skills, and why?
    • What makes a good question good?
    • What makes a bad question bad?
    • How can you turn bad questions into good ones?
    • When is it appropriate to ask a trick question, and why?
    • What questions can't or shouldn't you ask?
Monday Afternoon Half-Day Tutorials
M10 Over the Edge System Administration, Volume 2 David N. Blank-Edelman
David N. Blank-Edelman, Northeastern University

Who should attend: Old-timers who think they've already seen it all, and those who want to develop inventive thinking early in their career. Join us and be prepared to be delighted, disgusted, and amazed. Most of all, be ready to enrich your network and system adminstration by learning to be different. Previous attendance at Volume 1 of the series is recommended but not required.

Join us for volume two of the wildly successful Over the Edge System Administration class series. Once again we'll learn how to break the rules, abuse the tools, and generally turn your system administration knowledge inside out with the help of a whole new set of examples. This class is a second cornucopia of ideas for creative ways to take the standard (and sometimes not-so-standard) system administration tools and techniques and use them in ways no one would expect. We'll also cover some tools you may have missed. This class will take some of the concepts from the first installment and develop them even further.

Once again, we feel it is important to remind you: The teacher takes no responsibility should your head explode during this class.

Take back to work: Approaches to system administration you never dreamed of—but you wish you had!

Topics include:

  • How to exploit side effects to your benefit
  • Applying the arts and crafts you learned in camp to system administration
  • Pressing Web apps from places like Google and Yahoo! into service as sysadmin tools
  • How to perform SQL queries on your network equipment
  • How to use even more ordinary objects you have lying around the house to make your life easier (seriously!)

M11 The Joy of Running Diskless Linux NEW! Tobias Oetiker
Tobias Oetiker, Consultant

Who should attend: Linux/UNIX system administrators who manage several networked UNIX workstations or cluster nodes.

Would you like to reap all the benefits of a thin client infrastructure without compromising on raw CPU and graphics performance? Would you like to be able to set up new workstations before you even have the hardware on site? Would you like to be able to upgrade, patch, and test without any of your users noticing, until everything is ready, and then have a downtime of only one reboot? Would you like to be able to install 10 new workstations or cluster nodes in 5 minutes? If you answer yes to one of these questions, come join us on this adventure.

Running diskless Linux is as simple as using PEX to boot a server and hosting the filesystem on NFS. If you want to do this with a large number of machines, there are many ways to optimize procedures and provide unique features to your users.

Course examples will be based on Debian/Ubuntu, but we will address how this approach can easily be adapted to other distros.

Take back to work: The ability to slash your installation times and downtime, and reduce hardware costs as well.

Topics include:

  • Basic PXE netboot and NFS setup
  • Installing Linux without a workstation
  • Organizing NFS roots

M12 Problem-Solving for IT Professionals Strata Rose Chalup
Strata Rose Chalup, Project Management Consultant

Who should attend: IT support people who would like to have a better grasp of problem-solving as a discipline.

In the world of IT support, you build up a lot of specialized domains of knowledge that may or may not interact. As you will see, most types of troubleshooting rely on what you might call call "guided intuition"-- focusing your attention down a probable path of diagnosis, and then making an intuitive leap. If you haven't practiced your intuitive pole vaulting lately, don't worry. By using checklists and patterns to do brute-force troubleshooting, you will gradually build up a reservoir of understanding that will eventually have you shouting "Aha!" while other folks are still scratching their heads in puzzlement.

Take back to work:

  • A solid grounding in the process of solving problems
  • A framework on which to build specialized troubleshooting techniques that are specific to your environment
  • Confidence in your ability to apply logic and common sense to debug problems in complex interacting systems
  • How to trace out common patterns of interaction
  • How to apply basic principles to isolate symptoms and interactions between subsystems

What this class does not provide:

  • Detailed instruction in specific problem-solving situations, such as "what to do when the mouse stops moving"
  • Information on custom environments that are unique to your employer or organization
  • An intro or remedial tutorial on IT basics such as how DNS lookups occur or what TCP steps happen when a request to a Web server comes in

Rather than cover ground many of you already know, we have chosen to focus exclusively on the domain of problem-solving itself as a discipline, not on solving specific problems common to IT situations.

Full-Day Tutorials
T1 Introduction to Ruby, Rails, and Capistrano NEW! Faisal N. Jawdat
Faisal N. Jawdat, Consultant

Who should attend: Programmers, as well as system administrators with programming experience, who want to understand Ruby on Rails.

Over the past three years the Ruby on Rails Web development framework has gone from its first release to powering apps used by hundreds of thousands of users. In the process, Rails has dragged the Ruby programming language out of relative obscurity and into the mainstream of scripting languages. The elegance of the language and the power of the framework have gained a lot of attention both from Web 2.0 developers and from in-house application developers. What do you need to know to put Ruby on Rails to work for you?

This tutorial will provide an in-depth introduction to the Ruby language, the Rails application framework, and the Capistrano deployment system. We'll look at what each of these is, how it works, and when you should or shouldn't use it.

Take back to work: The ability to write scripts using Ruby and create and deploy your own applications using Rails and Capistrano.

Topics include:

  • The basics of the Ruby programming language, including the object model, the library, and functional features
  • A survey of significant Ruby packages and technologies, including when to use them
  • Ruby scripting for admins
  • Building a Rails application
  • Rails' sharp edges: the limits of easy and rapid app development and where you'll need to roll your own
  • How to decide what infrastructure to use to support your Rails application
  • Using Capistrano to deploy and manage distributed applications

T2 Configuring and Deploying Linux-HA NEW! Alan Robertson
Alan Robertson, IBM Linux Technology Center

Who should attend: System administrators and IT architects who architect, evaluate, install, or manage critical computing systems. It is suggested that participants have basic familiarity with system V/LSB-style startup scripts, shell scripting, and XML. Familiarity with high availability concepts is not assumed.

The Linux-HA project (http://linux-ha.org/) is the oldest and most powerful open source high-availability (HA) package available, comparing favorably to well-known commercial HA packages. Although the project is called Linux-HA (or "heartbeat"), it runs on a variety of POSIX-like systems, including FreeBSD, Solaris, and OS X.

Linux-HA provides highly available services on clusters from one to more than 16 nodes with no single point of failure. These services and the servers they run on are monitored. If a service should fail to operate correctly, or a server should fail, the affected services will be quickly restarted or migrated to another server, dramatically improving service availability.

Linux-HA supports rules for expressing dependencies between services, and powerful rules for locating services in the cluster. Because these services are derived from init service scripts, they are familiar to system administrators and are easy to configure and manage.

Take back to work: Both the basic theory of high availability systems and practical knowledge of how to plan, install, and configure highly available systems using Linux-HA.

Topics include:

  • General HA principles
  • Compilation and installation of the Linux-HA ("heartbeat") software
  • Overview of Linux-HA configuration
  • Overview of commonly used resource agents
  • Managing services supplied with init(8) scripts
  • Sample Linux-HA configurations for Apache, NFS, DHCP, DNS, and Samba
  • Writing and testing resource agents conforming to the Open Cluster Framework (OCF) specification
  • Creating detailed resource dependencies
  • Creating co-location constraints
  • Writing resource location constraints
  • Causing failovers on user-defined conditions

T3 Thinking About Security (Because They Really Are Out to Get You) NEW! Marcus Ranum
Marcus Ranum, Tenable Network Security, Inc.

Who should attend: Programmers and managers involved in the design, specification, deployment, or maintenance of computer-based applications. Does that sound perhaps overly broad? Well, it is—because virtually any software will, eventually, be security-critical whether you like it or not. Participants do not need any specific knowledge, though a basic understanding of computer security will help. People who attend this tutorial should come away with a high-level view of the pressure points in the development/deployment cycle where they can best stop the bleeding, along with a collection of mental tools that they can employ, and a framework for using them.

This tutorial is a high-level mental toolkit for thinking about security in applications and administration. It's aimed not at the tactical level of security (where most of us spend our time) but at the strategic level, and how to think about security as a problem, overall, rather than getting mired in the details.

Take back to work: Either a feeling of confidence or of terror; regardless, you will be much better equipped to cope with security.

Topics include:

  • The natural laws of security
  • Blocking and carrying
  • Whitelisting and blacklisting
  • Security in the design process
  • Touchpoints for adding security to development cycles
  • Data security

T5 Solaris 10 Security Features Workshop (Hands-on)Peter Baer Galvin
Peter Baer Galvin, Corporate Technologies

Who should attend: Solaris systems managers and administrators interested in the new security features in Solaris 10 (and features in previous Solaris releases that they might not be using).

Solaris has always been the premier commercial operating system, but it is also somewhat different from other UNIX/Linux systems. It has novel features and applications (some have been copied in other operating systems), and there are things you need to know to use them effectively and securely.

This course covers a variety of topics surrounding Solaris 10 and security. Note that this is not a class about specific security vulnerabilities and hardening; rather, it examines new features in Solaris 10 for addressing the entire security infrastructure, as well as new issues to consider when deploying, implementing, and managing Solaris 10. This will be a workshop featuring instruction and practice/exploration.

Take back to work: During this exploration of the important new features of Solaris 10, you'll not only learn what it does and how to get it done, but also best practices. Also covered is the status of each of these new features, how stable it is, whether it is ready for production use, and expected future enhancements.

Topics include:

  • Overview
  • Virtualization
    • Containers (a.k.a. Zones), light-weight virtual environments for application isolation and resource management
    • Installation
    • Management
    • Resource management
    • Other Solaris virtualizations: LDOMs, Xen
  • RBAC: Role Based Access Control (giving users and application access to data and functions based on the role they are filling, as opposed to their login name)
  • Privileges: A new Solaris facility based on the principle of least privilege; instead of being root (or not), users are accorded 43 distinct bits of privilege, sometimes spanning classes of actions and sometimes being confined to a specific system call
  • NFSv4: The latest version of NFS (based on an industry standard), featuring stateful connection, more and better security, write locks, and faster performance
  • Flash archives and live upgrade (automated system builds)
  • Moving from NIS to LDAP

  • Service Management Facility (a replacement for rc files)
    • New "Secure By Default" settings
  • Solaris Cryptographic Framework: A built-in system for encrypting anything, from files on disks to data streams between applications
  • Kerberos enhancements
  • Packet filtering with IPfilters
  • BART (Basic Audit Reporting Tool): similar to Tripwire, BART enables you to determine what file-level changes have occurred on a system, relative to a known baseline
  • Trusted Extension: Additions to Solaris 10 to make it "Trusted Solaris"
  • Securing a Solaris 10 system

Laptop Requirements:
Each student should have a laptop with wireless access for remote access into an instructor-provided Solaris 10 machine (if you do not have a laptop, we will make every effort to pair you up with another student to work as a group; your laptop does not need to be running Solaris).

Tuesday Morning Half-Day Tutorials
T6 Advanced Shell Programming Mike Ciavarella
Mike Ciavarella, University of Melbourne, Australia

Who should attend: Junior or intermediate system administrators or anyone with a basic knowledge of programming, preferably with some experience in Bourne/Korn shells (or their derivatives).

The humble shell script is still a mainstay of UNIX/Linux system administration, despite the wide availability of other scripting languages. This tutorial details techniques that move beyond the quick-and-dirty shell script.

Take back to work: An understanding of how to use the "lowly" shell to achieve lofty goals.

Topics include:

  • Common mistakes and unsafe practices
  • Modular shell script programming
  • Building blocks: awk, sed, etc.

T7 Management 101: Effective Communication Tools for Sysadmins NEW!
Elizabeth Zwicky Geoff Halprin Geoff Halprin, Consultant; Elizabeth Zwicky, Acutis, Inc.

Who should attend: System administrators who wish to become more proactive in managing their duties and to learn tools and tips that will assist them to communicate more effectively with their managers, users, and other important constituents of their services.

You may have noticed that being technically adept is not sufficient. You have to be able to deal with people: your fellow team members, your boss, your customers, the finance people, the legal department, and even upper management. You need them to do things for you (if it's only leaving you alone). System administrators generally find talking to people much more stressful and less productive than talking to computers. People do not operate by the same rules that computers do, and the process often seems random, irrational, or incomprehensible.

In this tutorial, we examine the many facets of communication and introduce various systems, tools, and techniques you can employ to ease your stress and improve your ability to attain the outcomes you desire.

Take back to work: Improved communication skills that will make you a more effective system administrator; an understanding of how communication works, so that it becomes a tool you can use instead of a source of frustration.

Topics include:

  • Oral communication
    • Effective listening
    • Effective talking
    • Presentations
  • Written communication

    • Personality types
  • Time management
  • Risk management
  • Project management

T8 Virtualization: VMs! What Are They Good For? NEW! Kyrre BegnumAeleen Frisch
Æleen Frisch, Exponential Consulting; Kyrre Begnum, Oslo University College

Who should attend: System administrators who are curious about the benefits of virtualization or who need to deploy it in their environment.

Virtualization is a hot computing topic these days, but you may be wondering whether it will actually benefit your site. When is virtualization appropriate, and when isn't it? What does it take to administer a virtual infrastructure? How do you handle challenges such as OS and software installation and backups? This course will answer those questions.

Take back to work: The ability to begin deploying virtualization in your environment, along with an understanding of the many tradeoffs you will need to address.

Topics include:

  • What virtualization is and what it can and cannot do for you
  • Available software and management options
  • Typical deployment scenarios and special-purpose solutions
    • Student labs
    • Testing environments
    • HPC
    • HA/load balancing
  • Dealing with legacy hardware

T9 Disk-to-Disk Backup and Eliminating Backup System Bottlenecks Jacob Farmer
Jacob Farmer, Cambridge Computer Services

Who should attend: System administrators involved in the design and management of backup systems and policymakers responsible for protecting their organization's data. A general familiarity with server and storage hardware is assumed. The class focuses on architectures and core technologies and is relevant regardless of what backup hardware and software you currently use.

The data protection industry is going through a mini-renaissance. In the past few years, the cost of disk media has dropped to the point where it is practical to use disk arrays in backup systems, thus minimizing and sometimes eliminating the need for tape. In the first incarnations of disk-to-disk backup—disk staging and virtual tape libraries—disk has been used as a direct replacement for tape media. While this compensates for the mechanical shortcomings of tape drives, it fails to address other critical bottlenecks in the backup system, and thus many disk-to-disk backup projects fall short of expectations. Meanwhile, many early adopters of disk-to-disk backup are discovering that the longterm costs of disk staging and virtual tape libraries are prohibitive.

The good news is that the next generation of disk-enabled data protection solutions has reached a level of maturity where they can assist—and sometimes even replace—conventional enterprise backup systems. These new D2D solutions leverage the random access properties of disk devices to use capacity much more efficiently and to obviate many of the hidden backup-system bottlenecks that are not addressed by first-generation solutions. The challenge to the backup system architect is to cut through the industry hype, sort out all of these new technologies, and figure out how to integrate them into an existing backup system.

This tutorial identifies the major bottlenecks in conventional backup systems and explains how to address them. The emphasis is placed on the various roles for inexpensive disk in your data protection strategy; however, attention is given to SAN-enabled backup, the current state and future of tape drives, and iSCSI.

Take back to work: Ideas for immediate, effective, inexpensive improvements to your backup systems.

Topics include:

  • Identifying and eliminating backup system bottlenecks
  • Conventional disk staging
  • Virtual tape libraries
  • Removable disk media
  • Incremental forever and synthetic full backup strategies
  • Block- and object-level incremental backups
  • Information lifecycle management and nearline archiving
  • Data replication
  • CDP (Continuous Data Protection)
  • Snapshots
  • Current and future tape drives
  • Capacity Optimization (Single-Instance File Systems)

T11 Management 201: Effective Team Management of System Administrators NEW!
Elizabeth Zwicky Geoff Halprin Geoff Halprin, Consultant; Elizabeth Zwicky, Acutis, Inc.

Who should attend: System administrators who have found themselves being given (or are hoping to be given, or are anticipating with apprehension) responsibilities for "wetware systems" (i.e., other people).

As you grow in seniority, a funny thing happens: you are expected to pass that wisdom on to others. You are given projects to run, teams to lead, apprentices to mentor, and ever larger budgets to manage effectively. The one thing, however, that you are almost never given is management training.

This tutorial examines many of the diverse areas of team management and provides you with an extensive set of insights, tools, and tips for conquering this brave new world.

Take back to work: The techniques you need to be effective in your "organization-facing" duties.

Topics include:

  • Sysadmin workflow
  • Personal and workgroup productivity

T12 So You Have Active Directory: Now What? A Guide to AD Integration for UNIX Sysadmins Gerald Carter
Gerald Carter, Centeris/Samba Team

Who should attend: System administrators who are tasked with integrating authentication, Web, and file/print services provided by UNIX hosts into an Active Directory domain.

Frequently, AD deployments are handled outside the UNIX infrastructure teams. This can leave UNIX/Linux sysadmins scratching their collective heads about how to make use of the new directory service and increase the amount of work duplicated by the UNIX server teams and the AD administrators. This tutorial will help reduce that workload for you.

Take back to work: In-depth understanding of the best approaches to managing your system services with Active Directory.

Topics include:

  • AD domain membership using Samba
  • NTLM and Kerberos authentication for Apache

T13 Next-Generation Storage Networking Jacob Farmer
Jacob Farmer, Cambridge Computer Services

Who should attend: Sysadmins running day-to-day operations and those who set or enforce budgets. This tutorial is technical in nature, but it does not address command-line syntax or the operation of specific products or technologies. Rather, the focus is on general architectures and various approaches to scaling in both performance and capacity. Since storage networking technologies tend to be costly, there is some discussion of the relative cost of different technologies and of strategies for managing cost and achieving results on a limited budget.

There has been tremendous innovation in the data storage industry over the past few years. Proprietary, monolithic SAN and NAS solutions are beginning to give way to open-system solutions and distributed architectures. Traditional storage interfaces such as parallel SCSI and Fibre Channel are being challenged by iSCSI (SCSI over TCP/IP), SATA (serial ATA), SAS (serial attached SCSI), and even Infiniband. New file system designs and alternatives to NFS and CIFS are enabling high-performance filesharing measured in gigabytes (yes, "bytes," not "bits") per second. New spindle management techniques are enabling higher-performance and lower-cost disk storage. Meanwhile, a whole new set of efficiency technologies are allowing storage protocols to flow over the WAN with unprecedented performance. This tutorial is a survey of the latest storage networking technologies, with commentary on where and when these technologies are most suitably deployed.

Take back to work: An understanding of general architectures, various approaches to scaling in both performance and capacity, relative costs of different technologies, and strategies for achieving results on a limited budget.

Topics include:

  • Fundamentals of storage virtualization: the storage I/O path
  • Shortcomings of conventional SAN and NAS architectures
  • In-band and out-of-band virtualization architectures
  • The latest storage interfaces: SATA (serial ATA), SAS (serial attached SCSI), 4Gb Fibre Channel, Infiniband, iSCSI
  • Content-Addressable Storage (CAS)
  • Information Life Cycle Management (ILM) and Hierarchical Storage Management (HSM)
  • The convergence of SAN and NAS
  • High-performance file sharing
  • Parallel file systems
  • SAN-enabled file systems

W1 Seven Habits of the Highly Effective System Administrator: Hints, Tricks, Techniques, & Tools of the Trade Mike Ciavarella Lee Damon
Lee Damon, University of Washington; Mike Ciavarella, University of Melbourne, Australia

Who should attend: Junior system administrators with anywhere from little to 3+ years of experience in computer system administration. We will focus on enabling the junior system administrator to "do it right the first time." Some topics will use UNIX-specific tools as examples, but the class is applicable to any sysadmin and any OS. Most of the material covered is "the other 90%" of system administration—things every sysadmin needs to do and to know, but which aren't details of specific technical implementation.

We aim to accelerate the experience curve for junior system administrators by teaching them the time honored tricks (and effective coping strategies) that experienced administrators take for granted and which are necessary for successful growth of both the administrator and the site.

The class covers many of the best practices that senior administrators have long incorporated in their work. We will touch on tools you should use, as well as tools you should try to avoid. We will touch on things that come up frequently, as well as those which happen only once or twice a year. We will look at a basic security approach.

Take back to work: Ideas about how to improve and to streamline your systems and your workload, and, just as important, where to look to find more answers.

Topics include:

  • Why your computers should all agree on what time it is
  • Why root passwords should not be the same on every computer
  • Why backing up every file system on every computer is not always a good idea

F3 Achieving High Availability (in Your Lifetime) Evan Marcus
Evan Marcus, QD Technology

Who should attend: System administrators and data center managers, but the material applies to developers and their managers and to IT managers as well.

What does high availability really mean? Do you need it? Do you already have it? How high is up? How up is high? Whom can you trust to give you a practical and useful answer, an answer you can apply to your data center and your systems? How can you sort through all of the marketing noise and really put high availability into place on your systems?

Every systems vendor, every OS vendor, every storage vendor, every networking vendor has his own definition of this very generic term—and all the definitions are different! Do any of these definitions apply to you and your systems? Probably not.

In this lively and upbeat tutorial, we'll give you some practical and useful information about high availability. We'll show you the relationship between cost and availability. We'll walk through our list of 20 key high availability design principles—the foundation for any critical system—and how you can get started down the path toward high availability without spending boatloads of money.

Take back to work: Simple and practical tools you can use right away to persuade the bean counters in your organization of the value of putting high availability techniques and practices into place.

Ultimately, availability is defined by the users of a system: can they use it, or not? With that in mind, we take the approach that high availability is a very broad science, affecting every aspect of system management.

Topics include, in reference to high availability:

  • Backups and restores
  • Storage
  • Security
  • Networking
  • The data center environment
  • Services and applications
