UKUUG WINTER CONFERENCE 2001
Speakers & Presentations

The names below are in alphabetical order:

Malcolm Beattie, University of Oxford

IBM Mainframe Hardware from a Linux Hacker's Viewpoint

Abstract: This talk is intended for those who are unfamiliar with modern IBM mainframe hardware (S/390 and the newly announced z900). It covers the architecture, reliability and performance characteristics of the hardware of a modern mainframe, compared and contrasted with those of traditional Linux/Unix systems. By the end, IBM jargon such as STI, ESCON, and SAP will hold as little terror as PCI and SCSI and the mild Linux/390 brainwashing will be lurking painlessly in your subconscious.

Andrew Cormack, UKERNA

How traditional security measures will shape up in the 21st century

Abstract: Traditional security models involving corporate firewalls may have been adequate for the 20th century, but will struggle in future. Higher speed networks and increasing variety of use challenge both the hardware and threat assumptions on which such designs are based. This talk will consider possible solutions to these new problems and try to predict what a scalable 21st century security system will look like.

Andrew Findlay, Skills 1st Ltd.

E-Commerce in Miniature: the Network Connection Booking System at Brunel University

Abstract: By Summer 1999, Brunel had 1000 study-bedrooms wired for networking and the administrative load was getting out of hand. We decided to build a web-based system for students to request connections, handle payment, and record the actual connections made. The application was written in Perl using a number of CPAN modules, and it runs under Apache using a mySQL database. The entire process from initial booking through payment, connection establishment, and eventual teardown is managed through the web interface.

Anton Holleman, Atos Origin

DHCP service

Abstract: This talk covers the rollout of a large (10,000 users over 10 subnets) DHCP system. Anton will talk about product selection, and cover many topics essential to the implementation of a system of this size, including management, the delegation of control to service providers, design for failover, migration and synchronisation with DNS. Delegates will gain an understanding of the issues involved in -- and winning strategies for -- the rollout of large DHCP systems, including both the potential pitfalls for the unprepared and the potential benefits to be gained.

Brad Knowles, Belgacom Skynet SA/NV

The Design and Implementation of Highly Scalable Email Systems

Abstract: Email systems can scale larger than had been thought possible! This talk will detail fundamental flaws in the current mailbox-per-user paradigm of standard off-the-shelf Local Delivery Agent software. It will describe how they can be scaled up to handle many more users, how virtually all synchronous metadata and file locking can be eliminated, how storage requirements can be reduced to grow at a rate less than O(n), and how various services can be broken out and handled by multiple separate servers.

Lindsay Marshall, University of Newcastle upon Tyne

The Newcastle Electronic Submission System

Abstract: Managing the collection and marking of coursework in universities has always been difficult. As the majority of students in all disciplines nowadays tend to use document preparation tools, the use electronic submission becomes much more practical. This paper describes the web-based submission system that is in use in the Department of Computing Science at the University of Newcastle and discusses some of the issues that arise regarding security, plagiarism detection and general management of coursework.

Stuart McRobert, Imperial College

Wireless Ethernet @ 11 Mbps

Abstract: The installation of IEEE 802.11b High Rate (Wi-Fi)-compliant 11 Mbps Ethernet base stations operating over the unlicensed 2.4GHz spectrum allows users with multi-vendor Wi-Fi compliant systems to interoperate from PDAs, laptops and even desktops. System and network support is easier since transparent roaming between base stations is possible, removing the need to search out a spare UTP outlet at each location. The ease and freedom of use is one of the key advantages of this technology.

Jim Reid, Nominum Inc.

The Design and Architecture of a Robust Global DNS Infrastructure: - GNS

Abstract: Nominum has launched a global DNS hosting service called GNS. This uses a scalable and flexible architecture to deliver robust, highly available DNS data. Customers can use the GNS name servers as master (primary), slave (secondary) - or even both! - for their DNS zones. This talk describes the architecture and the policy choices about criteria such as hardware platforms, location of servers and so on.
