Lightning Talks
Lightning talks are short talks/presentations that last no more than 10 minutes. This is a good opportunity to introduce a new project or tool perhaps to get some experience with presenting without having to go to a full talk. At the Sysadmin Miniconf it is planned that there will be at least half an hour of lightning talk sessions.
It is intended that the range of topics for lightning talks is broader than for full level talk

VESPER (Virtual Embraced Space ProbER) - Heartbeat for cluster of virtual machines - Sungho Kim
This talk presents VESPER (Virtual Embraced Space ProbER), the framework that monitors guest effectively on the virtualized environment using probing technology. VESPER is designed to provide evaluation criterion of system reliability and serviceability, used in decision-making for system switching or load balancing with live migration by cluster manager. In general, cluster manager exchanges messages between underlying nodes to check their health through network in a periodic way. In this way, however, the manager is not able to find out fault immediately and not to get detailed information about faulty nodes either.
To address those problems, VESPER injects Kprobes to guest to gather guest detailed information on guest health, from the manager on host. By communicating with guest in Kprobes through VMM infrastructure, VESPER is able to provide the manager with prompt fault detection in much faster way and with failure analysis facility to find out the cause in a fine-grained manner. Therefore, the manager can assure of by far lesser system down-time.
In addition, VESPER can invoke SystemTap to build and to handle Kprobes for the virtualized environment to improve on its usability. By extending SystemTap to the virtualized environment, VESPER will make suggestions on probing technology bridging host and guests as well.
In this talk, we explain how VESPER injects Kprobes into guest and how VESPER cooperates with the cluster manager to improve upon fail-over latency and failure analysis facility. Furthermore, the effectiveness and usability of VEPSER will be demonstrated by showing some use cases on Heartbeat cluster.
As VESPER is not strongly coupled to specific VMM, we also show its portability into KVM and lguest.

System administration - a programming perspective - Devdas Bhagat
While the practice of programming and programmer management has seen extensive progress in the past few decades, we have not seen such development in the field of system administration and operations.
System administrators are essentially programmers at a different level of abstraction. It behooves us to learn from programming philosophy and practice instead of reinventing the wheel.
We can draw analogies from programming techniques and bring those into our daily lives. We can use some programming paradigms to use in managing operations. The point of this talk is to trigger a discussion on what we can learn, and what concepts/paradigms are being used in operations today.

Mondorescue via PXE - Simon Lyall
This talk will give a quick overview on using the mondorescue tool to backup, restore and clone servers across a network.
Length: 10 minutes

Think - Frank Sainsbury
Frank Sainsbury, Itsoil Pty Ltd will give an outline of the tactical and strategic thinking process applied to the deployment in 2006 of Oracle on RHEL 4 with a view to deploying Application Express (APEX).
A review of the traps and pitfalls
Length: 10 minutes

SAGE-AU - Jacinta Richardson
About SAGE-AU and the benefits of joining.
Length: 5 minutes

Time management with Toodledo.com - Geoff Crompton
Length: 5 minutes

and what is this DKIM thing anyway? - Daniel Black
Domain Keys Identified Mail, DKIM, is a digital signature protocol for email. The presenter will talk about how it works, what kinds of things are and are not compatible with it.
There are some interesting social questions around DKIM deployment like is a second party signer (like a email list manager) responsible for stuff they digitally sign or is this a perceived stigma associated with signing.
Other system administrator questions like is it ok to break some email list compatibility to achieve a goal of more integrity and less phishing.
The presenter may also do comparisons with SPF and other weaker verification methods if time /interest permits.
