- The Future of System Administration (and What You Should Do to Prepare)
Adam Moskowitz, MathWorks
System Administration is changing faster and more radically that at
any time in its history. Like it or not, your job is probably going to
be very different in 10 years (and maybe even in 5 years); come hear
where the field is headed and what you should do if you want to stay
on the leading edge of system administration. (Sneak preview of the
recommendation: "stop being a sysadmin.")
Adam Moskowitz is a Senior Tools Developer at MathWorks in Natick MA;
in the past he has also been a system administrator, and his current
project marries those two disciplines and if it works, will make a
significant change in how system administration is done. Adam has been
in the field since 1978 but claims he keeps working "to keep food in
his puppy's bowl" (and to support his barbecue habit).

Josh Boon PCIP, Walt Williams
Compliance Soup: PCI DSS Condensed
Speaker: Josh Boon PCIP
An overview of PCI DSS 3.0 requirements and definitions. In this talk
I'll define types of credit card data and the storage requirements of
each, the types of merchants and service providers and the reporting
requirements of each, and summary of the twelve requirements of PCI
compliance. A participant should be able to take away from this talk
the basics of PCI and if it applies take the next steps towards
Compliance Soup: ISO, ISACA, SSAE, NIST and CSA Oh My!
Speaker: Walt Williams
A brief history of the alphabet soup that is security standards,
looking at the goals and scope of each of the commonly sought
certifications, applicability of each, challenges in
achieving/maintaining and the bang for the buck if you will, or are
they worth the time invested. The person shall be able to take away a
comparative understanding of the many standards available in
Josh Boon has worked across many verticals including higher education
and ecommerce primarily as a sysadmin expanding into compliance with a
focus on securing credit card data and personally identifiable
information. He now works for NutraClick in the role as a senior
sysadmin and internal security assessor and consults for other
companies in the PCI and PII space.

- Hyper-V and Openstack
Peter Pouliot, Microsoft
OpenStack is a rapidly evolving open source cloud computing
infrastructure typically thought of as a Linux centric
technology. Microsoft however has been involved with the OpenStack
from early on ensuring that Hyper-V, Windows and other core Microsoft
technologies interoperate within the OpenStack API framework. This
talk will discuss some key areas of integration between Microsoft
technologies and the OpenStack architecture while additionally
highlighting Microsoft's involvement in the OpenStack project
Development and Continuous Integration cycles.

- Radical ideas from The Practice of Cloud System Administration
Tom will highlight some of the most radical ideas from the new book
"The Practice of Cloud System Administration". The book focuses on
"distributed" or "cloud" computing and brings a DevOps/SRE sensibility
to the practice of system administration. Unsatisfied with books that
cover either design or operations in isolation, the authors created
this new reference centered around a comprehensive approach.
Some of the radical advice includes: improving uptime by using cheap
unreliable hardware, why you should crashing servers at random times,
and that you should make peace with outages.
(Note: Tom will not have books for sale at the talk, but he will sign
books you bring, even ones he didn't write. Ebook purchasers will
receive a sticker to put on their Kindle.)

Project Atomic: Server OS and app container delivery with Docker and OSTree
For many years, "traditional packaging" has been the default method
for software delivery and management on Unix systems; exemplified by
dpkg, RPM, and similar systems.
Project Atomic is a pattern that can be applied to a traditional
distribution (for example, Fedora, CentOS, Red Hat Enterprise Linux),
bringing together several upstream components: SELinux, Linux kernel
containers, Docker, (RPM-)OSTree, and orchestration frameworks such as
geard and Kubernetes.
This talk will explore the details of all of these technologies, with
a particular focus on the RPM-OSTree side, which provides atomic
upgrades and rollbacks for bare metal operating systems For example,
we'll look at why /home is a symlink to /var/home on an Atomic system,
and how configuration files in /etc are carried forward on upgrades in
a fully atomic fashion.
Colin Walters is a Senior Software Engineer at Red Hat in the Server
Experience group. He is the upstream author of OSTree, and has
contributed to a variety of Free Software projects, such as Emacs,
systemd, GNOME, OpenEmbedded, and both Debian and Fedora packaging.

Trying to Outpace Log Collection with ELK
This talk will detail the adventures of centralizing log data with the
ELK stack: Elasticsearch, Logstash, and Kibana. We wanted to
centralize logs from many very separate networks because it's a really
good idea to look at logs more than you probably are. The adventures
in this project include building concurrent prototypes with Logstash,
Graylog2, and Splunk. There's a bit of layer 7 routing and buffering
with RabbitMQ. I might get a bit DevOps-y in the description of using
Chef to deploy all the systems in this project. And finally, there are
some lessons learned about running distributed magical databases like
ElasticSearch in Amazon AWS. tldr; Lots of stuff only breaks when it
gets big enough to break.
Neil Schelly has been a sysadmin, developer, or consultant for most of
the last 20 years. Currently, he's a Principle Security Administrator
at Dyn, Inc in Manchester, NH. Lately, there's been more of a

Server Names? We don't need names where we're going!
How do you thrive in a environment where you don?t know your servers'
names, or if they'll disappear at any time? How do you build servers
with configuration management in this kind of environment? What do you
give up? This talk will discuss how you can name your hosts to make
life easier, and covers using cloudinit, autoscaling, mcollective,
logstash & sensu.
Matthew Barr has been a sysadmin (professionally) for over 15 years,
managing both cloud based & datacenter infrastructures. He's led the
ops group at Kensho & Snap Interactive, and the US sysops group for
MarkitServ. He recently finished building a production autoscaling
infrastructure in AWS without knowing his hostnames. He's a
co-maintainer on puppet-jenkins, and has contributed code to Puppet,
logstash, and various other projects.

Lay waste to waste
This talk will cover the basic ideas and some background behind Lean
and 6 Sigma (LSS), discuss their origins and then walk through some
examples while introducing the tools and techniques. Plus you get to
test the speaker by bringing your own problems and (hopefully) leave
with some ideas on how to tackle resolving the problem.
John Rouillard has been a system administrator trying to fix practices
for more decades than he cares to remember. His interest in formal
problem solving techniques developed by watching solutions that didn't
really solve problems but merely added more problems while allowing
the original issue to generate even more failures.

IT Project Management
20 years ago SAGE was defining IT job skills sets for HR
departments. Today (no surprise) IT departments are the heart beat of
the enterprise. With burgeoning budgets and even more complex
technologies management is trying to get more of a handle on their IT
processes and align them with standard management
methodologies. Sometimes with good results.
I will touch on TQM, ITIL, PMP & Agile practices and why some
practices work and some do not. Much of it depends on the culture of
the enterprise. Managing projects at large enterprises
(e.g. Microsoft), higher education (e.g. Harvard) and startups is
vastly different and requires a large bag of tricks. A major issue of
project management is who is "The Boss"? Is it the technical lead, a
non-technical manager or the project manager? In IT, it is often the
technical leader that is the real boss, regardless of titles.
Most Project Managers come from a business background. But IT Project
Managers better be able to understand the technical aspects of IT. If
an IT Project Manager asks naive questions like "Do you really need
fail over for DNS?" They will be abused and ignored by the technical
staff. Hence, many IT professionals see Project Managers as someone to
avoid. Management hears "The IT department is not cooperating" from
the Project Management staff.
I will share my horror stories, but actually explain how Good IT Project Management can help your IT department be more successful.

The Practical Gamemaster: Design & Execution of IT Emergency Operations Drills
Practical IT drill design brings together emergency response and
operations, business continuity, disaster recovery, and IT
architecture. During this talk, you will learn key concepts in
emergency operations center and incident headquarters design, methods
of introducing such concepts to your organization, and a sequence of
basic-to-advanced drill designs. Keeping IT folks engaged in a drill
simulation can be very challenging. Become a practical gamemaster
worthy of designing and executing drills on likely emergency scenarios
and realistic function failures for your organization. d10s included.

Solid State Disks
Solid State Disks are a relatively new technology, but on the surface,
seem to function exactly like traditional hard drives, only
faster. The truth is that the underlying way they store and retrieve
data are completely different - and understanding how and why can make
the difference in making sure that your disks last much longer and
maintain their performance.
This talk is an adaptation of a tutorial presented at LOPSA-East
2013. Because of time constraints, we'll be sticking to the most
relevant and interesting parts, and you will still be able to walk
away with a much better understanding of how to use SSDs in your
environment, and make well-informed purchasing choices.

The role of the central IT department is changing. No longer are users
happy inadequate IT organizations that create solutions that aren't
fully baked out. More executives just want to "throw some cloud on
it." Given the difference of user expectations between internal
services and what the outside appears to offer -- can you blame them?
This talk focuses on how IT lost its edge, and how IT organizations
can work towards being more human-focused and ultimately regarded as
business game-changers and not just a cost center.
Patrick Cable is an infrastructure system administrator at a local
research institute. He's currently working on managing a network used

Project Managers as Value Role in IT
Responding to "urgent/non-important" IT requests takes time away from
developing initiatives, completing complex operations, and evaluating
hardware or software technologies. Given this ever-present aspect of
IT, many departments believe that sysadmin, service desk, network, and
security areas are the obvious priorities when increasing
staff. However, if project management is valued as a staff position or
as a portion of present staffing roles, projects will have the high
visibility and accountability they deserve, plus the resources they
need in order to be Done Right.
The fundamentals of project management (sponsors, stakeholders,
resources, scope, methodology) and how they can be used to drive the
strategic vision of IT departments can be transformative for a
department and its staff.
This talk is not a tutorial about "how to be a project manager",
instead, attendees will hear about how to advocate for and develop
project management within their groups, completing projects despite
the seemingly endless lists of things to do.
Cathleen Bonner has worked in IT at the Broad Institute for over a
decade. She began in desktop support, shifted into research computing
engagement, and now manages the project and portfolio team. Cathleen's
goal has been to understand how to best synchronize the tricky triad
of customer engagement, IT culture, and strategic vision to produce
the best IT services possible. In her non-work time, she finds
fulfillment by volunteering with the Boston Area Rape Crisis Center,

BackupPC it's not just for desktops
Six years ago I embarked on a search for a new backup system for work.
This talk will start by discussing the requirements and evaluation
process for the backup system. This will be followed by a tour of
BackupPC and a discussion of how BackupPC is used to: backup multi TB
live databases, handle off site backups, handle bandwidth limitation
requirements for backing up sites scattered across the internet, how
compression and file de-duplication works to improve backup capacity
(fitting 52T of source data into 3.7T of backup space). The talk will
close with methods used for testing the integrity of backups and

Is the MooseFS distributed filesystem in your future?
Peter aNeutrino (LizardFS.org)
This talk will focus on features of MooseFS which make it very
interesting choice for storage alternatives. MooseFS is used all over
the world to store hundreds of petabytes of production data. Starting
with installation and configuration the talk will move on to
management of MooseFS. Then the reasons for creating the LizardFS fork
of MooseFS will be presented. Finally the challenges to be solved to
make the LizardFS an enterprise ready storage solution will be discussed.
Peter aNeutrino started working in Poland 20 years ago writing
assembler for Demoscene. He sharpened his Linux skills working for
Siemens, Google and Gemius in Poland. He has spent his last 3 years

Continuous Integration of Infrastructure
Stability is the name of the game for systems and networks operators. It's
what we expect and what our end-users expect, but it can be incredibly
difficult to achieve - a constant stream of security patches, dead-end
releases, broken software, broken hardware, and demands from other
internal stakeholders force change. Constant, never ending change.
Complicating this is the fact that these changes are rarely isolated. A
change on one system (particularly a lower-layer system like a router) can
ripple through entire services. We have, in effect, an integration
problem with every software update or configuration change we apply. So
to solve this, we look to the software development world to see how they
deal with it, and the answer is continuous testing and continuous
At TERC, we're currently combining configuration management (puppet),
hierarchical configs (hiera), monitoring (nagios), test
software (rspec/cucumber), and a software development CI
stack (jenkins/rake/vagrant) in order to address this. This talk will

of current software are, and touch on what my plans are to improve it.

Asterisk and VOIP
The near-universal provision of voice services and their terminals
(called "telephones") predates the Internet. While on some level,
voice traffic via TCP/IP is just another protocol, there are
challenges in making it "just work" like the traditional phones that
we are all used to. There are the technical issues of the nature of
the data, interfacing with the still robust telephone network, and of
course the UI expectations and experience.
That means that the protocols involved - SIP and the related suite -
were developed in the setting of a preexisting, mature, and complex
switched network. I found that from the perspective of a systems
administrator or network engineer there are complications,
terminology, and conventions that aren't necessarily obvious.
This talk will provide insight into the these technologies from that
perspective to allow you to grasp the protocols and the context in
which they interoperate, using an example implementation of Asterisk.

Mastering Human Communication Patterns for Techies
Missed human connections in the software industry account for most of
our project failures. Improving communication can dramatically improve
individual and team performance. Typical frustrations:
- They just don't get it
- They talked at you for an hour and made no sense
- That meeting was like a construction committee for the Tower of Babel
In the same way that programming languages have interfaces and design
patterns, so do human beings. Problems that appear technical in nature
can usually be traced back to failed interactions between
people. We'll explore:
- The human interface between system administrators, customers, and managers
- Key patterns of communication including negotiation and resolving miscommunication
- Examine techniques for how to listen to and understand others
- How to be heard and understood yourself.

Internet buffer bloat
Bufferbloat: Problem, Migitation, and Solution
VOIP and teleconferencing often perform much more poorly on today's
Internet than the Internet of a decade ago, despite great gains in
bandwidth. Lots of fiber, cheap memory, smart hardware, variability of
wireless goodput, changes in web browser behaviour, changes in TCP
implementations, and a focus on benchmarking Internet performance
solely by bandwidth, and engineer's natural reluctance to drop packets
have conspired to encourage papering over problems by adding buffers;
each of which may introduce latency when filled.
The mistaken quest to never drop packets has destroyed interactivity
under load, and often results in actual higher packet loss, as TCP's
congestion avoidance algorithms have been defeated by these
buffers. The lessons of the "RED manifesto" of 1997 have been
forgotten or never learned by a new generation of engineers.
Bufferbloat mitigation by tuning queue length is beginning to be
deployed in cable broadband systems. But solving bufferbloat requires
careful queue management that must be present anywhere a queue may
form. With the publication of the new CoDel AQM algorithm by Nichols
and Jacobson (and inclusion in Linux 3.5) we now have the opportunity
to solve rather than mitigate bufferbloat. I will also touch on
fq_codel, which combines stochastic fair queuing and CoDel, and why we
like the combination so much, and the remaining challenges.

Keeping up with Systems Management across Windows, Linux and Mac platforms.
How do you keep all of your systems (Windows, Mac, Linux)? Do you find
yourself having to use multiple toolsets? Enterprises keep adding new
types of system s (a resurgence in the Mac community and new Linux
applications being developed every day) that only increase the demands
on the systems administration team. On top of that, there are growing
regulatory and compliance (software licensing) demands placed on the
team. How can you streamline the systems management processes
(software distribution, asset management, patching, O/S deployment,

Cloud Filesystem HekaFS
Modern open-source distributed filesystems make it possible to provide
file services at a scale and level of availability that's finally
competitive with proprietary options. What they don't do - yet - is
enable secure sharing of those resources between multiple user bases
or organizations who pay for them. This talk will focus on how
GlusterFS works to solve the first set of problems, and how HekaFS -
which is based on GlusterFS - is solving the second. If you're tired
of having to deal with umpteen departmental file servers, each
configured differently, this approach might provide some relief.
Jeff Darcy has been working with network, cluster, and distributed
filesystems for about twenty years - since DECnet was still relevant
and NFSv2 was new. Since then he has gained scars from EMC's MPFS (for
which he was one of the initial developers), Lustre, and GlusterFS. He
is currently at Red Hat, where he's the project lead for HekaFS and

Converged Networks, Voice / Video / Storage / Data
How do you keep everything running smoothly while giving technologies
that require low or constant latency what they need and still be able
to watch that dog skateboarding on YouTube. Will discuss how Quality
of Service (QoS) works on both Layer 2 and Layer 3 devices and why you
probably need both. How should traffic be tagged and retagged with
policy decisions. If time permits we may even have some time to go
into why net neutrality isn't as cut and dry as you may think.
Technical details will be based off of Cisco devices but most concepts
will translate to any modern equipment.
Our speaker, Ryan Sutton, is a Systems Engineer at a local Gold
Certified Cisco Partner. Ryan specializes in large scale Routing and
Switching, Voice, and Data Center designs and implementations. His
solutions often include interworking between multiple networking
vendors and technologies. Current projects include sub-second core
convergence, and multi-city/multi-vendor VoIP installations.

Ruby: More Batteries, Fewer Brackets
Aaron D. Ball
Ruby may be most familiar as the language behind the Rails web
framework, and Perl as the "Swiss Army chainsaw" that no sysadmin can
live without, but they have a lot more in common than you might
think. Ruby comes out of the box with a great set of sysadmin tools,
from text processing to Unix system interfaces to TCP servers, and has
a syntax about as terse as Perl but with object-oriented and
functional-programming idioms that make your code easier to write and
understand. Whether you're new to scripting or you've been typing line
noise since 1987, this talk will show you another way.

The Path to Senior Sysadmin
Being a senior system administrator is about more than knowing all the
options to mount(8) or that modprobe is what's used to replace that
buggy kernel module with the latest version. Rather, a good senior
sysadmin will have a wide knowledge of relevant technical topics,
in-depth knowledge of one or more technologies, good interpersonal
skills, and the ability to manage "problem users" and will be
comfortable making presentations to and negotiating with mid- and
upper-level management. This talk will cover the skills a senior
sysadmin needs and why they are necessary and will provide some
suggestions for how to acquire these skills.
For nearly one-third of his sysadmin career, Adam Moskowitz held
titles such as Senior System Administrator, System Architect, and IT
Manager. Despite having returned to his roots as a programmer, Adam
remains active in the sysadmin community, including running the LISA
Advanced Topics Workshop and serving on the LOPSA Leadership
Committee. He claims he does all of this only to support his hobby

How Splunk manages our Junk
Jim Donn and Tim Hartmann
As environments grow and systems become more complex, building and
managing a usable centralized logging infrastructure can be a daunting
task. In this talk, we will walk through our real-life experiences
implementing Splunk as our centrali zed logging infrastructure for our
Network, Systems, Security, and Application teams. Over the past three
years, we have had to change our strategies and architecture to
account for organic customer growth, changes in team requirements, and
evolutions in technology.

Using MySQLtuner 2.0 to monitor and improve mysql performance
Sheeri K. Cabral
With help from Major Hayden, mysqltuner's original author, Sheeri
K. Cabral of the Pythian Group has modified mysqltuner to be more
comprehensive, to output information and to have a "spreadsheet" mode
where the results of mysqltuner are outputted as a single column, so
that you can easily compare subsequent runs of the modified
mysqltuner -- for example, running it monthly or weekly to see how
performance is progressing (or degrading). There is also a truly
offline mode that requires no database connectivity where files
containing the output of SHOW GLOBAL STATUS and SHOW GLOBAL VARIABLES
are used. This talk will go through how the the modified mysqltuner
works including how easy it is to change what is checked and the
thresholds, so that you can easily do one-off sanity checks as well as
Sheeri K. Cabral (The Pythian Group) is a noted MySQL community activist who recently wrote The MySQL Administrator's Bible.
