Events and Papers
</h2>
<hr>
<p>
OpenBSD developers, users and sponsors attend trade shows and conferences,
give papers, and organize "Birds Of a Feather" (BOF) sessions.
This is an opportunity to find out more about OpenBSD or just meet
like-minded people.
<!-- STYLE NOTES:
Place past events in most-recent-first order.
Make sure you change the tense from future to past when you move an item.
Use <br> tags instead of <p> to avoid gaps within an item.
Tagline formatting:
<li><strong>
<a href="LINK">EVENT NAME</a></strong>,
Month Day - Day, Year, Location.<br>
Use a 3 letter abbreviation for the month. Name anchors go on the line
with the <li> tag.
If you add talks about LibreSSL, OpenSMTPD, OpenNTPD, etc then please
also add them to the "papers" page of those projects' websites.

Jun 6 - 11, 1999, Monterey, California, USA.<br>
The <a href="http://www.usenix.org">USENIX Association</a>
provided The OpenBSD Project with a grant to underwrite the production
of CDs of OpenBSD 2.5. (We distributed the
release for free to attendees of the USENIX Annual Conference in
June.)
<br>
Usenix team members were involved in the authoring and
presentation of 4 OpenBSD-related papers:

<a href="http://www.linuxexpo.org">5th Annual Linux Expo</a></strong>,
May 18 - 22, 1999, Raleigh, North Carolina, USA.<br>
Some OpenBSD team members were at this conference selling OpenBSD 2.5 CDs,
OpenBSE T-shirts, as well as Blowfish T-shirts, which sold out very quickly
at a table donated by the Expo. OpenBSD was the only BSD represented at the
vendor exposition, and we had good chance to present a secure alternative
to Linux.
<p>
<li><strong>
<a href="https://www.ietf.org/proceedings/99mar/index.html">44th IETF
meeting</a></strong>,
Mar 15 - 19, 1999, Minneapolis, Minnesota, USA.<br>
Some OpenBSD team members were at this conference, in particular our
IPSEC developers.
<p>
<li><strong>
<a href="http://www.europen.se/NordU99">NordU99 -- The first
EurOpen/USENIX Conference</a></strong>,
Feb 9 - 12, 1999, Stockholm, Sweden.<br>
A couple of OpenBSD team members were there and some of the swedish user
society as well. OpenBSD CDs were sold at a booth and at the end of a
security talk, the project got applauded for its continuous strive of auditing
security sensitive parts of the system.
<p>
</ul>
<h3>1998</h3>
<ul>
<li id="ipsec98"><strong>
IPsec/VPN Interoperability tests & seminar</strong>,
Dec 14, 1998, Stockholm, Sweden.<br>
OpenBSD was represented as one of about a dozen
<a href="https://man.openbsd.org/?query=ipsec&sektion=4">IPsec</a>
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.
<p>
<li id="lisaboston-98"><strong>
<a href="http://www.usenix.org/events/lisa98">LISA '98: 12th Systems Administration
Conference</a></strong>,
Dec 6 - 11, 1998, Boston, Massachusetts, USA.<br>
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.
<br>
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.

<li><strong>
<a href="http://www.disc.unam.mx/eventos_anteriores/disc98/">DISC - Seguridad en
Cómputo 98</a></strong>,
Nov 2 - 7, 1998, Mexico City, Mexico.<br>
Theo de Raadt gave a talk about security auditing, sponsored by
<a href="http://www.core-sdi.com">CORE SDI S.A.</a>, an Argentine
security auditing company who strongly believes in the future
of OpenBSD. (<a href="papers/mexico98-slides.ps">Slides are available</a>).
<p>
<li><strong>IP-dagarna</strong>,
Oct 29 - 30, 1998, Stockholm, Sweden.<br>
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 <strong>isakmpd</strong>,
an IKE implementation funded by Ericsson Radio Systems and developed
primarily for the OpenBSD IPSEC stack.
<p>
<li><strong>NCEE '98</strong>,
Oct 9 - 10, 1998, Auburn, Maine, USA.<br>
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.
<p>
<li><strong>
<a href="http://www.acm.uiuc.edu/conference/1998/">Reflections/Projections
1998</a></strong>,
Oct 2 - 4, 1998, Champaign-Urbana, Illinois, USA.<br>
Theo de Raadt spoke in a panel about Open/Free software with Eric
Raymond and others.
<p>
<li><strong>
<a href="http://press.oreilly.com/pub/pr/797">O'Reilly and
Associates Open Source Developer Days</a></strong>,
Aug 21, 1998, San Jose, California, USA.<br>
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.
<p>
<li id="defcon98"><strong>
<a href="http://www.defcon.org/html/defcon-6/defcon-6.html">Defcon 6.0</a></strong>,
Jul 31 - Aug 2, 1998, Las Vegas, Nevada, USA.<br>
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.
<br>
Almost 100 OpenBSD 2.3 CDROMs were sold (we ran out again). The primates
at <a href="http://www.monkey.org">monkey.org</a> 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.
<p>
<li><strong><a href="http://www.blackhat.com/html/bh-usa-98/bh2-index.html">BlackHat Sessions</a></strong>,
Jul 29 - 30, 1998, Las Vegas, Nevada, USA.<br>
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.
<p>
<li id="usenix-neworleans"><strong>
<a href="http://www.usenix.org/publications/library/proceedings/usenix98/index.html">Usenix Annual Technical Conference</a></strong>,
Jun 15 - 19, 1998, New Orleans, Louisiana, USA.<br>
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).
<br>
The terminal room PCs ran OpenBSD 2.3. We sold many CDROMs. The
first style of OpenBSD T-shirt also sold quite well.
<p>
<li><strong>
<a href="http://www.usenix.org/publications/library/proceedings/sec98/index.html">Usenix Security</a></strong>,
Jan 26 - 29, 1998, San Antonio, Texas, USA.<br>
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
(<a href="papers/security98-slides.ps">slides available</a>).
<br>
The terminal room PCs ran OpenBSD 2.2.
<p>
</ul>
<h3>1997</h3>
<ul>
<li><strong>
<a href="http://www.hip97.nl">HIP</a></strong>,
Aug, 1997, Almere, Netherlands.<br>
Niels held a
<a href="http://www.citi.umich.edu/u/provos/papers/hip97-tcpip.html">talk</a>
about the problems of unencrypted TCP/IP connections, offering IPSEC as
possible solution.
<p>
<li><strong>HOPE</strong>,
Aug, 1997, New York, New York, USA.<br>
The terminal room consisted primarily of DECstations running
OpenBSD 2.1. Once again, the <a href="http://www.lopht.com/">L0phT</a>
people had very good things to say about our security.
<p>
<li id="defcon5"><strong>
<a href="http://www.defcon.org/html/defcon-5/defcon-5.html">Defcon V</a></strong>,
Jul 11 - 13, 1997, Las Vegas, Nevada, USA.<br>
At this conference, the OpenBSD team sold 100 or so 2.1 release CDROMs.
<br>
Since this is the primary security conference, many speakers said very
good things about our stance on security... particularly people like
<a href="http://www.lopht.com">the L0phT</a>.
<p>
<li><strong>
<a
href="http://www.usenix.org/publications/library/proceedings/ana97/index.html">Usenix Annual Technical Conference</a></strong>,
Jan 6 - 10, 1997, Anaheim, California, USA.<br>
Theo de Raadt held a BOF ("Birds Of a Feather", i.e. a meeting of people
interested in the same thing) about OpenBSD.
