1998

• IPsec/VPN Interoperability tests & seminar, Dec 14, 1998, Stockholm, Sweden (in swedish)
  OpenBSD was represented as one of about a dozen IPsec implementations who were tested for interoperability. The tests were successful, both for the technology in general, and for OpenBSD in specific. We managed to communicate encrypted with every vendor present, and to negotiate keys via IKE with everyone capable.

• LISA '98: 12th Systems Administration Conference, Dec 6 - 11, 1998, Boston, Massachusetts
  More than 10 OpenBSD team members showed up. By far, OpenBSD was the largest representative group from free software at the conference. Usenix gave us a table in the vendor area where we sold 2.4 CDROMs, 2.3 "wire-frame" T-shirts, and the new 2.4 embroidered "Because security matters..." T-shirts, polos, and sweaters. An OpenBSD BOF was held one evening, led by Theo de Raadt. A PalmPilot schedule loader was at the membership booth, powered by OpenBSD.
  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.

  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.

• 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).

• 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.
