Abstract

Managing e-mail services has become more than tedious in recent years. With the rise in spam, viruses and and worms implementing a scalable system can be quite difficult. It must be able to quickly filter out harmful messages without interfering with legitimate user e-mail.

This talk will cover one proven configuration that uses low-error anti-spam techniques and anti-virus software. It uses sendmail's milter API with Sender Validation and Sender Profile Facility (SPF) along with Clam AntiVirus. Some discussion of each of these technologies as well as the headaches you must be prepared to accept will be discussed.

For the past 6 years, I have been a computer systems engineer at the UVA Engineering School. My work involves managing web, SQL and file servers, Beowulf clusters, Linux and Windows workstations. I provide primary user support to the MAE and MSE Departments. The languages I currently use (in no particular order) are C/C++, PHP, HTML, bash, Java, and JavaScript.

I was born in Charlottesville and have a BS from Ga. Tech and a MS from UVa and have lived in Charlottesville since 1971. My first computer job started in 1980 with Academic Computing (predecessor of ITC) in the basement of Gilmer Hall at UVa. We had a CDC mainframe with four 300MB drives and 2 HP minicomputers. The CS Department had a Vax 11-780 and UVa has grown from there. My first "home computer" was a CompuPro dual CPU (8080 and 80286) machine with 2 8" floppies and a ADM5 console and no hard drive.

The presentation is available here.

Abstract

In search of a small, cool-running, robust home firewall/router, I revived a 10-year-old SPARC station by installing OpenBSD. Using OpenBSD's built-in packet filter/NAT engine, 'pf', I turned this cute little workstation into a virtually trouble-free firewall with far better security than conventional so-ho router appliances.

Come see how easy it is to set up OpenBSD on computers of yester-millennium and why OpenBSD and sun hardware is a match made in computer heaven.

Abstract

Asterisk, a Linux-based Open Source PBX (Private Branch Exchange) and IVR (Interactive Voice Response), enables individuals and organizations an unprecedented amount of power, freedom and cost savings over traditional telephony solutions. Asterisk, distributed under the GNU GPL, is a full-featured phone system that provides caller id, voicemail, event notification, call queuing, multiple person conferencing, and other advanced management features. Asterisk supports analog services (FXO, FXS, T1, E1, PRI) and Voice-Over-IP technologies (IAX, SIP, H.323). This presentation provides an introduction to Asterisk and includes a discussion of the basic configuration files.

Abstract

Adrian Filipi will speak about how cryptography works and is applied to securing digital information and communications. This talk does not get into the math of cryptography, and instead focuses on how to use cryptography meaningfully. When finished, you should understand why you should prefer not to use passwords with SSH and instead use public keys (DSA or RSA). It will also be clear why the way SSL is currently deployed by 99.9999% of the world is vulnerable to MitM (man-in-the-middle) attacks.

Abstract

Ryan Bokko, the author of QHacc, will present The Q Home Accountant (QHacc) package. It is an accounting package aimed at the home user.

QHacc is built exclusively using the Qt Toolkit, and integrates into KDE as well. It has advanced features like graphing and reporting, transaction templates, journaling, and database atomicity. He will give a brief introduction to this program, followed by a hands-on demonstration of some of its capabilities.

QHacc is hosted at Source Forge at http://qhacc.sourceforge.net.

Abstract

Brian will provide a high-level overview of the emerging practice of aspect-oriented programming (AOP) as a way of building modern software systems by keeping cross-cutting concerns appropriately modularized (don't worry, this mantra will be explained). AOP is an evolution from the successes of Object-Oriented Programming (OOP) and Design Patterns, not a revolution. The focus will be on AspectJ and Java-based AOP, but a quick survey of other techniques, languages and resources will be presented.
