Hans van de Looy and Brenda Langedijk,
Using the FreeBSD ports collection to perform network forensic analysis (tutorial # F2am)

Hans Van de Looy has been hacking operating systems since 1979 and has not stopped since. His private home-based network contains several computers running all kind of neat stuff using mostly BSD and windows flavored operating systems. Since his graduation he has worked for several companies in various functions, ranging from senior software developer at a nuclear science development site, development manager for a telecommunications company, product marketing manager for a high-end computer manufacturer and ethical hacker for one of the largest computer centers in the Netherlands. He has presented lectures, workshops and tutorials at universities and conferences like SANE, H2K, DefCON, ITSMF and HAL2001. A couple of years ago he decided to to start his own business and founded Madison Gurkha BV (http://www.madison-gurkha.com). A privately held company providing techical security oriented consultancy services like penetration testing and training. His interests include but are not limited to security in its broadest sense, reading, music and sailing. Hans can be also be contacted at: hans@blackhats.org.

Poul-Henning Kamp,
FreeBSD GEOM (tutorial # F2pm)

Poul-Henning Kamp believes that UNIX is the best OS ever made so far, he is convinced we can still make it better and he has been trying to since the early eighties. Ever since Minix 1.0 came out, Poul-Henning has been running UNIX on his laptop, and via 386BSD he came to FreeBSD where he sat on the Core Team from 1994-2000. Poul-Henning has been release engineer for a number of FreeBSD releases, written, rewritten and cleaned up many pieces of FreeBSD kernel, written a memory allocator, a password scrambler, the beerware license and generally been having a good time. Poul-Henning lives in Denmark with his wife, his son, his daughter about ten FreeBSD computers and one of the worlds most precise NTP clocks. He makes a living as an independent contractor doing all sorts of magic with computers and network.

Albert Mietus,
Securing syslog on FreeBSD

Albert has been using FreeBSD as long as the product exists; he started with 386 BSD, indeed on a 386-CPU. That system is still in use, now as a firewall. Albert is a hardcore Unix-user, running FreeBSD whenever possible. "Running Unix isn't a goal by itself", he always says, "but using FreeBSD can often simplifyi ng the solution". Especially in environments where stability, security and quali ty are important, the open and standardised implementations of FreeBSD come in h andy. Albert is currently working for a customer, where the FreeBSD implementation of syslog will be used for securing and auditing both infrastructure and applicatio ns. In Albert's current architecture, up to 100K applications and systems, from router to mainframe can be connected and use syslog for logging. Everything, fr om simple application-debugging to tracking of complex financial systems can be handled with this logging-infrastructure. By using the security enhancement, sys log can be used even in hostile environments. Albert is key-designer of this pro ject. He has both started the architecture, argued for syslog, and will assist w ith the implementations of the security-enhancements.

Marco Molteni,
Using SCTP with Partial Reliability for MPEG-4 Multimedia Streaming

I discovered Unix at University, and I have fallen in love with BSD since then. After graduating in Computer Science, I left Italy for California, where I worked for SRI International. I am now based in France and work for Cisco Systems. In my various experiences I have enjoyed hacking on FreeBSD and more esotic platforms. Among my interests are network and system programming, network protocol design, computer security and system administration. I like spending my spare time creating welded sculptures designed by my wife Francesca.

Bram Moolenaar,
All For One Port, One Port For All

Bram Moolenaar has worked on open-source software for more than ten years. He is mostly known as the creator of the text editor Vim. Currently he is working on a project called A-A-P, which is about creating, distributing and installing (open source) software. His background is in computer hardware, but these days mostly works on software. He still knows on which end to hold a soldering iron though. In the past he did inventions for digital copying machines, until open-source software became his full-time job. He likes travelling, and often visits a project in the south of Uganda. Bram founded the ICCF Holland foundation to help needy children there. His home site is www.moolenaar.net.

Riccardo Scandariato,
Advanced VPN support on FreeBSD systems

Riccardo Scandariato received his master degree in telecommunication engineering at Politecnico di Torino on December 2000. Currently he is a PhD student at the Control and Information Engineering Department of Politecnico di Torino.

Dag-Erling Smørgrav,
Authentication in FreeBSD 5.0

Over the past year, support for advanced user authentication in FreeBSD has grown considerably through the systematic integration of PAM in almost all authentication-related utilities. Administrators can now choose from a wide variety of both software- and hardware- based authentication methods for both local and remote access. In the course of this presentation, we will discuss and demonstrate a selection of these methods and the ways in which they can be put to fruitful use.

Ignatios Souvatzis,
A shared write-protected NFS root file system for a cluster of diskless machines

Ignatios Souvatzis is "System Programmer" (in reality, a nonlinear combination of system administrator, tape operator, kernel hacker, and user advisor) at Chair V of the Computer Science Department at the University of Bonn. He is also a NetBSD key developer. His main tasks have been some device drivers, a new ARP system, and maintaining the Amiga port. Sometimes, those assignments overlap. He studied Physics and Astronomy in Bonn. He has used nearly everything running VMS from the 11/780 to MicroVAX, and everything running Ultrix from the DECstation 2100 to the 5000/260 and even a CDC Cyber 172 and a Convex to do astronomical data reduction. Earlier at University, he (ab)used lots of different systems, from IBM 360 to 4331 to PC to solve the eight queens problem, has written test programs for 8085 and UNIBUS control boxes for the new accelerator at the physics department. In his second University year, he was introduced to Unix (on a z8000 box) at a small software company. He seldom admits that he was teaching an introduction to BASIC at an adult education center in late 1981/early 1982 (but it paid driving home for the weekends).

Valeriy Ushakov,
Porting NetBSD to JavaStation-NC

Valeriy started with 2.9BSD on a PDP-11. His involvement with NetBSD started with the sparc port and has been expanding along with his small but growing collection of hardware. He became a NetBSD developer in 2001. His day job involves working with Java AWT, so hacking device drivers is a refreshing change.

Gerald Wilson,
MacOS X on a budget

Gerald Wilson has worked for more than twenty years in technical computing, as p rogrammer, designer, and technical manager. In that time, Gerald has worked on c ontrol systems for laboratories and factories, avionics systems, military commun ications systems, and most recently naval command systems. Over the years he has also spent many happy hours as network and systems manager for technical develo pment teams. Gerald has an unhealthy depth of knowledge about Macintosh computer s, a working knowledge of UNIX, and can install Windows at a pinch. Gerald think s that Dr Edgar David Villanueva Nunez should be the next Secretary General of t he United Nations.

Marko Zec,
FreeBSD network stack virtualization

Marko Zec has five years of industry experience with networking technologies. While working for IBM, he was responsible for design and implementation for a couple of the largest WAN/ATM enterprise networks in Croatia.
