  The terminal room ran OpenBSD 2.4 on 45 machines. Obviously trust in OpenBSD had increased since many people,normally wary of security problems of open terminal rooms, were seen using the machines.

• DISC - Seguridad en Cómputo 98, Nov 2 - 7, 1998, Mexico City
  Theo de Raadt gave a talk about security auditing, sponsored by CORE SDI S.A., an Argentine security auditing company who strongly believes in the future of OpenBSD. (Slides are available).

• IP-dagarna, Oct 29, 30 1998, Stockholm, Sweden (in swedish)
  At this conference, entirely devoted to IP, Niklas Hallqvist from the OpenBSD team held a talk on the IKE (a.k.a ISAKMP/Oakley) key management protocol and experiences from the implementation of isakmpd, an IKE implementation funded by Ericsson Radio Systems and developed primarily for the OpenBSD IPSEC stack.

• NCEE '98, Oct 9 - 10, 1998, Auburn, Maine, USA
  An extensive after-action report was sent to advocacy@openbsd.org. While sales of shirts and CDROMs left much to be desired, we did have good opportunities to further project visibility and highlight its strengths.

• Reflections/Projections 1998, Oct 2 - 4, 1998, Champaign-Urbana, Illinois, USA
  Theo de Raadt spoke in a panel about Open/Free software with Eric Raymond and others.

• O'Reilly and Associates Open Source Developer Days, Aug 21, 1998, San Jose, California, USA
  OpenBSD team members were on-hand to discuss OpenBSD's role among the other free software projects available. They also sold some CDs and T-shirts.

• Defcon VI, Jul 31 - Aug 2, 1998, Las Vegas, Nevada, USA
  The router to the outside world was an OpenBSD 2.3 box. It was involved in a "capture the flag" competition in which an entire room of crackers attempted to break into it and machines running other operating systems. The OpenBSD box was not broken into.
  Almost 100 OpenBSD 2.3 CDROMs were sold (we ran out again). The primates at monkey.org brought 2.3 "wire-frame" OpenBSD T-shirts to the conference and sold almost 200 of them. The proceeds from the sales were donated to the OpenBSD project.

• BlackHat Sessions, Jul 29 - 30, 1998, Las Vegas, Nevada, USA
  Theo de Raadt presented a talk entitled "Auditing software for security" about the OpenBSD security auditing team's process and the lessons the team learned. The talk concentrated on how our process fixes bugs -- not just holes -- since one never knows when 5 bugs will act together to become a hole.

• Usenix Annual Technical Conference, Jun 15 - 19, 1998, New Orleans, Louisiana, USA
  At Usenix 1998 there was a strong OpenBSD presence both in the Freenix and normal tracks. Theo did a general talk about what the OpenBSD project offers. Angelos held a panel about IPSEC (which is quite an OpenBSD topic since IPSEC development at that time was so much further ahead in OpenBSD than anywhere else).
  The terminal room PCs ran OpenBSD 2.3. We sold many CDROMs. The first style of OpenBSD T-shirt also sold quite well.

• Usenix Security, Jan 26 - 29, 1998, San Antonio, Texas, USA
  At this conference, Theo presented an evening talk which basically turned into a list of fixed security problems and cautionary tales about subsystems in which future problems may be encountered (slides available).
  The terminal room PCs ran OpenBSD 2.2.

1997

• HIP, Aug, 1997, Almere, Netherlands
  Niels held a talk about the problems of unencrypted TCP/IP connections, offering IPSEC as possible solution.

• HOPE, Aug, 1997, New York, New York, USA
  The terminal room consisted primarily of DECstations running OpenBSD 2.1. Once again, the L0phT people had very good things to say about our security.

• Defcon V, Jul 11 - 13, 1997, Las Vegas, Nevada, USA
  At this conference, the OpenBSD team sold 100 or so 2.1 release CDROMs.
  Since this is the primary security conference, many speakers said very good things about our stance on security... particularly people like the L0phT.

• Usenix Annual Technical Conference, Jan 6 - 10, 1997, Anaheim, California, USA.
  Theo de Raadt held a BOF ("Birds Of a Feather", ie. a meeting of people interested in the same thing) about OpenBSD.
