M2 Securing Linux Servers
Rik Farrow, Security Consultant
Who should attend: Linux system administrators and security managers familiar with Linux sysem administration, whether you manage a handful or clusters of Linux systems.
Linux servers start out very secure: it's what you do with them when you use them that can create insecurities. A straight Linux server install runs minimal services and has few users and a very restrictive firewall, which is a great security posture but is pretty useless for most purposes. As users are added, services enabled, and holes punched through the firewall, the security can deteriorate quickly.
This class will show you how to maintain a strong security posture through careful configuration and proper use of Linux tools and services. Linux contains tools and software that can be enabled to slow brute-force attacks against user accounts, can notice when your accounts have weak passwords or are under attack, can keep services and software up to date, and can sandbox applications to prevent even zero-day attacks. The class will focus on attacks most recently seen, including attacks on mail and Web servers.
Take back to work: Techniques for securing and maintaining Linux servers.
- Minimizing risk with appropriate restrictions
- Managing and tracking application vulnerabilities

Have you checked the Perl version on your server recently? Chances are high that it is Perl 5.8 or maybe, if you are lucky, 5.10. Perl 5.8 was originally published in 2002, more than nine years ago. The current version of Perl is 5.14. It's high time you updated both your Perl setup and your Perl knowledge.
While so much attention, excitement, and disappointment have been focused on Perl 6, Perl 5 has continued to flourish. For the past two years there have been regular scheduled releases, with one major release each year. There has been talk about Enlightened Perl and Modern Perl. CPAN, the Central Perl Archive Network (where most of the extension modules for Perl are hosted), sees up to 200 package updates and releases every week.
In this course you will learn about core features that have been added to Perl since 5.8, and you will get to know some popular extension packages that bring even more fun to working with the only programming language that adapts to the style of its users.

M10 Perl 6 for Perl Users and Sysadmins NEW!
Tobias Oetiker, Consultant and author of RRDTool
Who should attend: People who work with Perl and would like to try their hand at working with a real implementation of Perl 6.
Perl 6 was conceived over ten years ago. The long gestation time has prompted many eulogies and second-system-syndrome remarks. All the while, Larry Wall and a bunch of die-hards have been working at designing and implementing a new language called Perl 6. Perl 6 is heavily inspired by Perl 5, but it also introduces many new concepts on all levels.
For years Perl 6 existed mainly on paper. With Rakudo, we now have a real implementation of the language at our disposal. This class is based on actual working Rakudo code, focusing on upgrading your Perl knowledge to Perl 6.
Take back to work: The ability to harness Perl 6 to solve problems with less effort and more fun than ever before.

M12 Monitoring Servers, Networks, and Lunchrooms with Zenoss
David Nalley, Cloud.com
Who should attend: Sysadmins and managers evaluating Zenoss as a monitoring platform or nascent in their exploration of systems/network monitoring. Sysadmins experiencing scaling/scope issues with other tools such as RRDtool or Nagios will walk away learning much. Participants are expected to be relatively well versed in operating system and application mechanics.
To quote Tom Limoncelli, "It's not a service if you aren't
monitoring it." A decade ago, monitoring effectively meant either
cobbled together, home-grown scripts or massive and inflexible
enterprise applications. In the intervening time, monitoring has
become a must-have for even the smallest environment, the hodgepodge
collection of scripts has grown to become unmaintainable, and the
massive enterprise applications, while working well, are slow to
respond to the changes happening everywhere. In that interim,
monitoring with open source software has effectively become the de
facto standard, because, like the browser and operating system,
monitoring is now a commodity.
Take back to work: A good grasp of the basics of Zenoss and monitoring theory and the ability to put this information to use immediately, along with a rudimentary understanding of some of the more esoteric features Zenoss offers.
Zenoss is free/libre open source software for monitoring applications,
networks, servers, and even whether the restroom is in use.

Tuesday Full-Day Tutorial
T1 SELinux (Security-Enhanced Linux)
Rik Farrow, Security Consultant
Who should attend: Linux system administrators and security managers who want or are required to use SELinux. Participants must be familiar with Linux system administration; previous frustration with SELinux is expected but not required.
SELinux provides an extra layer of security for most Linux systems—if you leave it enabled. Most commonly, SELinux gets disabled as the first step when debugging system problems, even when it is not the problem. SELinux can stop many attacks, even previously unknown (zero-day) attacks, as it confines applications' access to files, directories, commands, and network sockets.
This class will show you how to work with SELinux: how to determine if SELinux is blocking an application and how to adjust policy to move beyond problems. SELinux includes many tools for viewing audit logs, file and process contexts, modifying policy, and even interpreting log messages, and you will learn how to use these tools. You will learn how to modify file contexts, add new policy, monitor logs both graphically and in text-only mode, and, most importantly, how to recover full SELinux coverage on systems where it has been disabled. The class will cover reading and modifying existing policy where necessary, so that changes to services, such as non-standard directory locations, are accommodated. The class will also investigate adding new, custom services to SELinux policy.
This class includes exercises that will be performed using a provided VM.
Take back to work: The ability to run Linux servers and desktops with SELinux enabled and to modify policy to handle configurations not supported by the default policy.

T3 Backups, Archiving, and Life Cycle Management: Riding the Wave of Data Proliferation NEW!
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.
Most IT organizations report exponential data growth over time, and whether
your data doubles every year, every two years, or every five years, the simple
fact remains that if your data capacities double, then both the capacity and
the performance of your backup system must double. All of this doubling
stresses traditional approaches to data management. Thus, it is no surprise
that backup/recovery is one of the most costly and unforgiving operations
in the data center. Meanwhile, most IT organizations also report that the
vast majority of their unstructured data is seldom or never accessed. Files
accumulate year after year, choking the backup systems and driving up costs.
This course explores two main ways to manage the data deluge: (1) optimize
backup systems by eliminating bottlenecks, streamlining operations, and
bulking up backup infrastructure; and (2) manage the life cycles of
unstructured data so that files that are not in active use can be managed
separately from files that are in active use. We start by offering a simple
framework for defining business requirements and comparing solutions at a
high level. We then delve into the various mechanisms for lifecycle
management and for eliminating backup system bottlenecks. Some time is spent
exploring storage systems that have built-in mechanisms for data protection
and lifecycle management.
Take back to work: Ideas for immediate, effective, inexpensive improvements to your backup systems and a vision for how you might deploy a lifecycle management system that fits your organization.
- Formulating strategies for data protection and lifecycle management
- Identifying and addressing backup system bottlenecks
- Managing fixed content
- Hierarchical storage management and data migration
- In-band versus out-of-band approaches to file lifecycle management
- Breathing new life into tape storage
- Deduplication: separating hype from reality
- Object-based storage models for backup and archiving
- Self-healing and self-protecting storage systems
- Leveraging the cloud for backup and archiving
T4 Real-World Insights on How to Secure and Route Your Linux Network

T5 Introduction to Cloud Storage NEW!
Gerald Carter, Likewise Software
Who should attend: Administrators and developers looking for answers about cloud storage providers, APIs, and end-user devices.
The term "cloud" means different things to different people. Adding "storage" to the phrase make the concept more concrete by applying the concept of elastic computing to something everyone produces and consumes each day—data. However, you must still navigate a maze of both terminology and offerings before arriving at any decisions. This class will help answer your questions.
Take back to work: An understanding of what cloud storage is and is not, as well as ways to leverage both private and public storage offerings in your network.

T7 A Sysadmin's Guide to Navigating the Business World
Mark Burgess, CFEngine; Carolyn Rowland, National Institute of Standards and Technology (NIST)
Who should attend: IT people and sysadmins interested in taking their career to the next level, improving their relationship with senior management, and increasing their value and marketability.
As a system administrator, you are already a crack technical analyst or engineer, but does your management understand the value and importance of your work? When you ask for staff or funding to support new or existing efforts, does management readily support you? Does management look to you to develop the future of IT services in your organization? Do you feel you have enough time to focus on projects and innovation instead of fire-fighting?
If you answered no to several of the above questions, then this course is for you. The first step toward improving your professional quality of life is to create a positive and collaborative relationship with your management. So why not take responsibility for the relationship? Senior management makes the decisions about budget, staffing, and, often, new services, without understanding the full impact of their decisions. What if you could make yourself part of that process? What if it was easy to ask your management for more resources because they already believed strongly in your positive contribution to the organization?
System administrators often have all the responsibility for IT systems, but none of the control. In this course we bring the two sides together by teaching the system administrator how to communicate effectively so that management will listen and understand. You can use the tactics presented here to increase your value in the organization and improve your marketability.
Make business look good, and you become an important asset to your organization. Your management will appreciate these skills because you will be demonstrating your value in ways they understand and that empower them to make smart IT investment decisions. In turn, your professional credibility increases, putting you in a position to influence decisions impacting your role in the organization.
Take back to work: Skills to help you develop a productive relationship with your management.

W1 Using Amazon Web Services
William LeFebvre, Digital Valence, LLC; Marc Staveley, Consultant
Who should attend: System administrators who currently use or are considering the use of Amazon Web Services (AWS), as well as individuals who are tasked with supporting AWS for production services, especially if they are unfamiliar or uncomfortable with the command-line tools and the Web-based interfaces supplied by Amazon. Experience with cloud computing is not required. Experience with the installation and support of basic tools and languages (especially Java and Ruby) would be beneficial. Time will only permit us to study the creation and support of Linux instances in the Amazon cloud.
Amazon offers a solid collection of cloud services through the Amazon Web Services (AWS). These include virtual machines and storage, load balancers, replicated databases, content data delivery, and automatic scaling and monitoring. AWS provides a very rich API to facilitate building applications that utilize these services, but the actual user interfaces can be difficult to master. This tutorial introduces the Amazon Web Services and describes the more popular services and how they can all fit together to support an infrastructure. It provides in-depth instruction on using the user-level interfaces for the more popular services: EC2, EBS, ELB, S3, Cloudfront, and others. Three interfaces will be taught: the Web console, the Firefox plug-in Elasticfox, and the command-line tools. Cautions and pitfalls will be presented along the way to ensure that the student will not make some common mistakes of first-time AWS users.
Take back to work: Knowledge of the techniques, pitfalls, commands, and programs that will help you make effective use of the Amazon cloud.
- Introduction to AWS
- Elastic Compute Cloud (EC2)
- Elastic Block Store (EBS)

W2 ZFS: A Filesystem for Modern Hardware
Richard Elling, Nexenta Systems
Who should attend: Systems engineers, integrators, and administrators who are interested in deploying ZFS on Solaris, Mac OS X, or FreeBSD. Participants should be familiar with storage devices, RAID systems, logical volume managers, backup, and file system features. Special emphasis will be placed on integration considerations for virtualization, NAS, and databases.
File systems developed in the mid-20th century were severely constrained by the storage hardware available at the time. ZFS was conceived with an eye toward the hardware of the future and how storage will evolve. This presented an opportunity to rethink how file systems use storage hardware. The result is a new way of managing data which can evolve as the hardware changes while remaining compatible with earlier notions of file system use. Along the way, new concepts such as the Hybrid Storage Pool provide new opportunities for optimization, efficiency, and data protection. In this tutorial, ZFS will be examined from the bottom up, to build a solid understanding of the data-hardware interface, and then from the top down, to provide insight into the best ways to use ZFS for applications.
Take back to work: A solid understanding of the concepts behind ZFS and how to make the best decisions when implementing storage at your site.
- Evolution of hardware and file systems
- Storage pools
- RAID data protection
- Import/export and shared storage
- Pool parameters and features

W3 Pacemaker and Linux-HA: World-Class High Availability Software
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/), together with its child project, Pacemaker, is the oldest and most powerful open source high-availability (HA) package available, comparing favorably to well-known commercial HA packages. This software runs on a variety of POSIX-like systems, including FreeBSD, Solaris, and OS X.
Pacemaker+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.
Pacemaker 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 and Pacemaker.
- General HA principles
- Installation of the Linux-HA
and Pacemaker software
- Configuration overview

W4 Solaris Dynamic Tracing (DTrace)
James Mauro, Oracle Corporation
Who should attend: Sysadmins and other production support staff that need to look at systems and figure out what they're doing or why they're running slowly on a regular basis. Some general programming knowledge will be assumed, along the lines of writing shell, awk, or Perl scripts, as well as general familiarity with using and administering systems running some variant of UNIX.
This tutorial covers using the Dynamic Tracing (DTrace) technology that originated in Solaris and OpenSolaris and is now available in Mac OS X 10.5 (Leopard) and FreeBSD 8.0. DTrace is a framework that allows for dynamically inserting points of instrumentation, called probes, in the operating system (kernel) as well as user processes.
This session will combine slides with live demos of DTrace on several operating systems.
Take back to work: How to use DTrace to understand the behavior of your systems and the workloads they run, whether you're chasing a performance problem or pathological behavior or you simply wish to better understand how applications are using the underlying system.
- Introduction to DTrace
- DTrace components

F1 Linux Performance Tuning
Theodore Ts'o, Google
Who should attend: Intermediate and advanced Linux system administrators who want to understand their systems better and get the most out of them.
The Linux operating system is commonly used in both the data center
and for scientific computing applications; it is used in embedded
systems as small as a wristwatch, as well as in large mainframes. As
a result, the Linux system has many tuning knobs, so that it can be
optimized for a wide variety of workloads. Some tuning of the Linux
operating system has been done "out of the box" by
enterprised-optimized distributions, but there are still many
opportunities for a system administrator to improve the performance of
his or her workloads on a Linux system.
This class will cover the tools that can be used to monitor and
analyze a Linux system, and key tuning parameters to optimize Linux
for specific server applications, covering the gamut from memory
usage to filesystem and storage stacks, networking, and application
