Plenary Session Salon E/F Open Source and Proprietary Software: A Blending of Cultures Alan Nugent, VP & CTO, Novell Listen in MP3 format As a 20-year provider of proprietary software for the enterprise market, Novell has built products and a culture around proprietary (or closed) software. Within the last 18 months, we have embraced open source development and Linux and have injected them into our corporate DNA. While different, the two approaches are not mutually exclusive. In fact, I would argue embracing open source as a proprietary company is more straightforward than an open source company trying to move "up the stack." In this talk I will examine the myths, challenges, and opportunities for companies attempting to understand the best of both worlds. Alan F. Nugent serves as chief technology officer of Novell. Prior to Novell, Alan was the Managing Partner, Technology, at Palladian Partners. Mr. Nugent has successfully led many different technology organizations. He serves on the Board of Directors and on the Technical Committee for the Object Management Group and is a widely respected writer and speaker on OT, BPR, and Information Management. He sits on the board of directors of several technology startup companies.

SIG SESSIONS Salon F Advanced System Administration SIG Session: Automating System and Storage Configuration CHAMPS: A Schedule-Optimized Change Management System Alex Keller, IBM T.J. Watson Research Center IBM's CHAnge Management with Planning and Scheduling (CHAMPS) system gleans and exploits detailed structural knowledge about software dependencies in a distributed system. CHAMPS' ability to gather and optimize such information according to administrator-defined objectives, available resources in server pools, and financial constraints enables high-quality optimized solutions for quick and reliable software provisioning tasks, such as installations and updates. Autonomics in System Configuration Paul Anderson, University of Edinburgh A computing installation is created from a collection of bare hardware and a repository of software. These same components may be used to build "fabrics" with very different objectives, from a GRID computing cluster to a network of desktop workstations. We use the term "system configuration" for the task of turning these raw components into an integrated system that satisfies the given objectives. However, we also want to maintain these objectives in the face of changing requirements and external influences. To do this, a system needs to be able to adapt autonomically. This talk discusses some of the problems of specifying and implementing configurations in an autonomic environment.
GURU SESSIONS Harvard Embedded Linux Bart Massey, Portland State University Bart is the faculty advisor to the Portland State Aerospace Society (PSAS). PSAS has been using Linux as the embedded OS for launch control, flight sequencing, and in-flight telemetry in the extremely unforgiving environment of their 12-foot-high supersonic rocket. Bart has also been involved with the efforts of Keith Packard and Carl Worth in developing the Linux/X infrastructure for embedded devices in conjunction with the handhelds.org project. The session will be fun-filled and informative for embedded Linux novices and experts alike. Session focus will be on cost-effective, practical Linux solutions for a variety of embedded environments.

SIG SESSIONS Salon F Advanced System Administration SIG Session: System Administration: The Big Picture The Technical Big Picture Alva Couch, Tufts University Network and system administration are still considered bottom-up processes: integrating disparate hardware and software into a usable computing infrastructure, building a pyramid of capabilities and services upon a foundation of reliable core systems. By contrast, the true goal of network and system administration is to support a particular top-down mission or pattern of use, by expressing organizational goals as subgoals in an upside-down pyramid of needs. Looking at the profession from a top-down perspective leads to new metrics for the profession, some surprising and controversial conclusions, and several interesting questions for the future. The Human Big Picture Tom Limoncelli, Independent Consultant Imagine rolling out a security patch, a new application, or a new operating system to 40,000 PCs—it's 65% communication, 25% technical work, and 10% ego management. System administration on a large scale becomes a study of human relationships: managing large teams of people on a project, managing expectations and resources with upper management, and coordinating with a user base. Psychology and public relations become just as important as technical prowess. Why aren't those skills taught to CS majors?

SIG SESSIONS Salon F Advanced System Administration SIG Session: Large Storage Autonomic Policy-based Storage Management Kaladhar Voruganti, IBM Almaden Research The cost of managing ever-growing storage is now a dominant IT expense. Storage administration complexity is growing, and the amount of storage a single administrator can manage is not growing as quickly as a site's storage capacity. We present a new approach: autonomic policy-based storage management. This approach dramatically increases administrative leverage by moving storage admin to software that understands high-level policy goals with respect to performance, availability, security, and backup/restore. The talk discusses the architecture, algorithms, and implementation details of a policy-enabled storage-network planner—a key component of the overall policy-based storage management solution. Experiences with Large Storage Environments Andrew Hume, AT&T Research I have worked with various aspects of the recording and billing systems for a large telecommunications company for the last several years. We process feeds from various UNIX, MVS (Cobol and PL/1), and AS/400 systems, to the tune of 4000 files comprising 300–700GB of new data per day. This data streams into several PC clusters, where it is chewed on, compressed, added to databases, and copied onto tape. This is not trivial to do. Sure, we have about 50TB of disk, but that doesn't go as far as it used to. Managing the space is harder than it ought to be; annually managing 2–3 million files and their life cycles is awkward, as is controlling the processing of these files. This talk will discuss these and other challenges in both hardware and operating system choices and will discuss solutions we've found.

Plenary Session Salon E/F Network Complexity: How Do I Manage All of This? (PDF) Eliot Lear, Corporate Irritant, Cisco Systems Listen in MP3 format In the evolution of computers and networks, we have developed complex mechanisms to manage one, the other, or both. We organize teams based on technology or task, only to find that the tools they use converge at times and then diverge again. I'll discuss the latest convergences in the context of distributed systems management, network management, security, and voice in a world of ISPs, ASPs, Web services. It all boils down to this: why can't we manage the network just like one large UNIX box? Eliot Lear started his career developing distributed management tools for UNIX in 1987 at Rutgers University. From 1991 through 1998 he was part of a team that ran a large computer manufacturer network. Since 1998, Eliot has been the Corporate Irritant of Cisco Systems, focusing on the area of network management, network applications, and cross-functional integration.

Plenary Session Salon E/F Thinking Sensibly About Security in an Uncertain World Bruce Schneier, Counterpane Internet Security, Inc. Listen in MP3 format All security decisions involve trade-offs: how much security you get, and what you give up to get it. When we decide whether to walk down a dimly lit street, purchase a home burglar alarm system, or implement an airline passenger profiling system, we're making a security trade-off. Everyone makes these trade-offs all the time. It's intuitive and natural, and fundamental to being alive. But paradoxically, people are astonishingly bad at making rational decisions about these trade-offs. Security expert Bruce Schneier discusses this notion of security trade-offs and how we are all "security consumers." He makes use of a five-step process to explicate these intuitive trade-offs and shows how the process can be applied to decisions both small and large. Learn how security works in the real world, and what you can do to get the security you want . . . not the security that is forced upon you. Internationally renowned security expert Bruce Schneier has written eight books, including Beyond Fear and Secrets and Lies, as well as the Blowfish and Twofish encryption algorithms. Schneier has appeared on numerous television and radio programs, has testified before Congress, and is a frequent writer and lecturer on issues surrounding security and privacy.

SIG SESSIONS Salon F Security SIG Panel: The Politicization of Security Moderator: Avi Rubin, Johns Hopkins University Panelists: Ed Felten, Princeton University; Jeff Grove, ACM; Gary McGraw, Cigital Like it or not, security has become political. Technologists once interested only in how security apparatus works and how it fails need to be cognizant of the ramifications of their activities. These days, announcing a security flaw can lead to personal and professional attack by corporate spin control. Pointing out that the emperor has no clothes can wind you up in jail. Demanding secure voting induces smear campaigns—even in a democracy. This panel is about what happens when security and politics collide. Using particular real world examples, we will discuss the politicization of security. Examples we will discuss include: The RIAA and the DMCA Electronic voting apparatus Compiler flaws and Microsoft security response We will debate the finer points of: Disclosure of security problems Civil liberty and security Fighting stupid security Come join us!
GURU SESSIONS Harvard High-Performance Linux Clusters Greg Bruno, San Diego Supercomputer Center Greg is a core developer for Rocks, a high-performance Linux cluster distribution developed at SDSC.

SIG SESSIONS Salon F Security SIG Panel: Wireless Devices and Consumer Privacy Organizers: Ari Juels, RSA Laboratories; Richard Smith, Consultant Panelists: Markus Jakobsson, RSA Laboratories; Frank Schroth, Ulocate; Matthew Gray, Newbury Networks Location-based services, RFID, Bluetooth, and 802.11 promise a more seamless interface between the physical and virtual worlds. Like many information technologies, they have also ignited fears among privacy advocates, ranging from the legitimate and pressing to the fantastical. The goal of this panel is to adumbrate and compare the threats to individual privacy and civil liberties posed by several popular wireless technologies. Is RFID a greater threat to privacy than a GPS-enabled mobile phone? Is Bluetooth an emerging threat? How much do 802.11 devices reveal about you when used in public venues? More generally, the panelists will consider how technology itself can effectively combat the very privacy problems it is creating.

Plenary Session Salon E/F Cheap Hardware + Fault Tolerance = Web Site Rob Pike, Google, Inc. Listen in MP3 format The Web is too large to fit on a single machine, so it's no surprise that searching the Web requires the coordination of many machines, too. A single Google query may touch over a thousand machines before the results are returned to the user, all in a fraction of a second. With all those machines, the opportunities for parallelism and distributed computation are offset by the likelihood of hardware failure. If one machine breaks on average every few years, a pool of a thousand machines will have machines break on a daily basis. A key part of the Google story is that by designing a system to cope with breakage, we can provide not only robustness, but also parallelizability, efficiency, and economies of scale. Rob Pike is a member of the Systems Lab at Google, Inc. In 1981, while at Bell Labs, he wrote the first bitmap window system for UNIX. He has since written a dozen more. He is a principal designer and implementer of the Plan 9 and Inferno operating systems and co-author with Brian Kernighan of The UNIX Programming Environment and The Practice of Programming.

Plenary Session Salon E/F The State of the Spam Eric Allman, CTO, Sendmail, Inc. Listen in MP3 format No one needs to be told that email spam is a serious problem, but some people don't truly understand how serious it is. The speaker now gets about 900 spams every day, a great many of them in character sets he can't even render, and is seeing a doubling rate of about four months. Many solutions have been proposed, falling primarily into two areas, legislative and technological. The current state of spam will be reviewed, including some thoughts about the current legislative climate (and whether legislation has any chance of doing any good) and quite a bit about the various technologies that are being discussed and deployed. Although opinions will be offered, no conclusions will (or can) be drawn in an environment changing as quickly as we are seeing with email today. Eric Allman is the original author of Sendmail, co-founder and CTO of Sendmail, Inc., and co-author of Sendmail, published by O'Reilly. At UC Berkeley, he was the chief programmer on the INGRES database management project, leader of the Mammoth project, and an early contributer to BSD, authoring syslog, tset, the -me troff macros, and trek. Eric designed database user and application interfaces at Britton Lee (later Sharebase) and contributed to the Ring Array Processor project for neural-network-based speech recognition at the International Computer Science Institute. Eric is on the Editorial Review Board of ACM Queue magazine and a former member of the Board of Directors of the USENIX Association.
