Workshop Presenter

Implementing Puppet configuration management for sustainable service delivery (half day)

Puppet is a system administration framework, written entirely in Ruby and capable of scaling from managing symlinks and Subversion checkouts in your home directory up to managing networks of hundreds or thousands of machines. It reframes the management problem, talking about resources like users, hosts, and packages, instead of the contents of files like /etc/passwd and /etc/hosts.

Puppet handles translating these resources to the appropriate file contents or commands, using what is called "Providers" for supporting a given platform or application. This higher-level resource layer makes the management problem drastically easier, allowing you to focus on how to configure and manage your services, rather than the intimate details of each individual application or operating system.

This workshop will cover managing a system with puppet, from adding users and packages, up to creating & managing databases, installing web applications and tools, and maintaining services on the system. Integration with tools such as Augeas, Nagios and Cucumber will also be covered.

Attendees should have a basic understanding of Linux and the LAMP (Linux Apache Mysql PHP) stack, be familiar with common cli enditors, and will need a laptop with 2Gb of ram, and a working install of Vmware player or workstation.

IPv6 Workshop (full day)

IPv6 is our next hurdle. This workshop will go into some details and examples on implementing IPv6 at your organisation/campus. Plug-and-play is the word for IPv6 and we hope you will see why after attending this workshop. We suggest you bring your IPv6 ideas with you as we will be discussing them on the way.

- Why IPv6?
- IPv6 address space overview and subnetting
- Implementation models (dual stack, static or dynamic tunneling)
- Cisco static and dynamic routing using EIGRPv6
- Multicast via IPv6
- Security (Fortigate UTM, ACLs)
- Supported Cisco equipment and IOS revision
- Good/Bad/Ugly

Karl Auer, from IPv6 Now Pty Ltd, will also feature as a guest speaker.

The Application of 3D Virtual Worlds in Higher Education (half day)

There is a growing interest in the use of 3D virtual world technology as a communications and collaboration platform in many areas of business and the community. Education and Training appears to be one area in which virtual worlds may have a lot to offer.

One obvious area is in delivering of the learning experience itself. In a virtual world participants can communicate in a manner which is very natural and intuitive without the need to be in the same physical location. This is very conducive to learning as not only can a lecture be delivered to a number of students but these students can also easily participate in the kind of ad hoc discussions and interactions which are one of the benefits of learning in a group. Another benefit is the ability to create specialised environments which are directly related to the subject matter. For example, law students may be able to participate in a mock trial in a virtual court room.

Perhaps not so obvious is the use of virtual worlds for other functions. Most Universities maintain one or more call centres providing many kinds of administrative and student support functions and many of these could be provided effectively through virtual worlds.

Many organisations, including a number in Higher Education, have experimented with the use of virtual worlds by using Second Life by Linden Lab. This has proved many of the expected benefits of these worlds but has also highly some challenges. Second Life is effectively a public space, with no guarantee of privacy or security or even the integrity of the environment.

Nortel's Immersive Internet technology builds on the successful aspects of existing virtual worlds while adding functionality that adds value to specific commercial environments, especially in Education. Areas such as security, privacy and integration with existing online learning systems enable wider adoption of virtual worlds in Universities. There are also many enhancements to the virtual world experience itself such as full spatial audio and embedding of other media.

This workshop will discuss some of the applications of virtual worlds in higher education including real world experience and feedback from working with a number of organisations within industry in general and in Higher Education in particular.


  • Introduction to Virtual Worlds and a Tour of Nortel's Immersive Internet environments
  • Experiential & Contextual Learning overview
  • Steps to identifying where to start for a virtual world
    • How to look at opportunities in your organisation for the application of virtual worlds to achieve a real ROI
  • Interactive Session
    • One or more workshop participants will be asked to provide input based on their organisation's situation so the principles from the previous section can be applied to a real world case study

IP Telephony and Unified Communications Experiences (half day)

This half day workshop will provide attendees with the learnings and experiences of implementers (from CQU, QUT, UQ & UTas) of IP Telephony and/or unified communications solutions (Microsoft OCS, Cisco, etc). It is not the traditional instructive form of workshop but rather an interactive workshop where attendees will learn from other university technical staff who have deployed trial or production implementations - what they have discovered worked well, didn't work, what may have been overlooked, issues of scaling, what things to avoid and the ongoing support and maintenance aspects. Attendees will be encouraged to question presenters and contribute their own experiences on the various aspects of deployments.

Specifically presenters will include issues of:


  • QoS vs bandwidth considerations (internal & external to the organization)
  • Softphones vs Fixed handsets
  • Security/encryption
  • Provisioning, de-provisioning & MACS


  • Design (scope/integration into existing PBX etc.)
  • Initial experiences and issues
  • The client experience and their feedback
  • Federation
  • Where to from here?

Merv Connell (CQU), Jouni Stroja (QUT), Graeme Wilson (UQ) and John Miezitis (Uni of Tasmania) will contribute their experiences.
