Central Syslog

Ogg version (7 minutes), MP3 version (3 Mb, 7 minutes)
Setting up a central syslog server.
- If you are concerned about the security of your logs, use a dedicated machine and lock it down.
- Keep clocks in sync.
- You may need to change log rotation schedule in /etc/newsyslog.conf. You can rotate based in size and/or time. This can be as much a policy decision as a hardware decision.
- On central log host, change syslogd flags to listen to network. Each BSD does this differently, so check the man pages. Also, check out the -n flag for busy environments.
- Make sure host firewall allows syslog traffic through.
- Be careful to limit syslog traffic to just the trusted network or hosts. FreeBSD man page refers to syslogd as a "remote disk filling service".
- For heavy logging environments, it is important to have a dedicated network. A down syslogd server can create a lot of "ARP who-has" broadcasts.
- Most network devices such as printers and commercial firewalls support sending to a central syslog server. Take a look at "Snare" for Windows hosts.
- To send messages from a Unix host, specify the host name prepended with @ instead of a file for logging in /etc/syslog.conf. For example, change /var/log/xferlog to @loghost.mydomain.biz. You can also copy and edit the line to have it log to both a local file and a remote host.

Why I like the CLI
Source: bsdtalk
Added: 01 September 2007
Tags: bsdtalk, cli, will backman
Ogg version (12 minutes), MP3 version (6 Mb, 12 minutes)
Why I like the CLI:
- Uses minimal resources. Less space, less memory, fewer dependencies.
- Transparency. GUI hides internals, limits options.
- Similar between Unix-like systems. GUI tools seem to change every week.
- Remote management. SSH rocks.
- Everything is text. Configs, devices, output. CLI is natural complement.
- Pipes and scripts. One time is hard, a thousand times is easy.
- Only need a few tools. Grep, sed, awk, vi, cron.
- Text config files. Easy to version, share, and comment.
- Requires reading skills instead of clicking skills.
- Much faster when you know what you are doing.

One Time Passwords
Source: bsdtalk
Added: 14 June 2007
Tags: bsdtalk, security, one time passwords
Ogg version (6 minutes), MP3 version (4 Mb, 6 minutes)
- Important when you don't trust the computer you are using, such as a library computer or internet kiosk.
- Available by default in Free/Net/Open BSD.
- FreeBSD uses OPIE, Net/Open use S/Key.
- One time passwords are based on your pass phrase, a non-repeating sequence number, and a seed.
- Initial setup should be done directly on the server.
- "skeyinit" for Net/Open, "opiepasswd -c" for FreeBSD.
- Enter a pass phrase that is not your regular account password.
- Find your current sequence number and seed with "opieinfo" or "skeyinfo", for example: "497 pc5246".
- Generate a list of the next 10 passwords and write them down, using "opiekey -n 10 497 pc5246" or "skey -n 10 497 pc5246".
- When you log in from a remote machine that might have a keystroke logger, you can now use a one time password instead of your regular password.
- For OpenBSD, log in as account:skey, for example "bob:skey", which will cause the system to present the s/key challenge.
- For NetBSD, the system will always present you with the s/key challenge if it is configured for your account, although you can still use your regular password.
- FreeBSD by default will force you to use a one time password if it is configured for your account.
- If you want both OPIE and password authentication, FreeBSD allows you to list trusted networks or hosts in /etc/opieaccess.
- Instead of carrying a list of passwords around, you can use s/key generators on a portable device that you trust, such as a palm pilot.
- For more info, check the man pages.

- "ctrl" and "alt" and "backspace" keys at the same time will zap X.
- "X & xterm -display :0"
- "xterm -geometry +300+300"

This paper provides a how-to embed FreeBSD. A console
server built form an AT91RM9200 based ARM system
will be explored. This paper will talk about the
selection of hardware. It will explore creating
images for the target system, as well as concentrate
on different alternatives for deploying the system.
A number of different options exist today, and no
comprehensive guide for navigating through the
choices exists today. This paper will explore the
different alternatives that exist today for producing
images targeted at different size requirements. The
differing choices for storage in an embedded
environment are explored. The techniques used to
access rich debugging environments are discussed.

In the past ten years most of the research in network
protocols has gone into TCP, leaving UDP to languish
as a local configuration protocol. While the majority
of Internet traffic is TCP, UDP remains the only
IP protocol that works over multicast and as such
has some specific, and interesting uses in some
areas of computing. In 2008 we undertook a study
of the performance of UDP multicast on both 1Gbps
and 10Gbps Ethernet networks in order to see if
changing the physical layer of the network would
give a linear decrease in packet latency. To measure
the possible gains we developed a new network
protocol test program, mctest, which is capable of
recording packet round trip times from many hosts
simultaneously and which we believe accurately
represents how many environments use multicast. The
mctest program has been integrated into FreeBSD and
is now being used to verify the proper operation
of multicast on various pieces of 10Gbps hardware.

In recent years, traditional branches of engineering
like Civil, Chemical, Mechanical, Electrical and
Industrial Engineering are requiring extensive
computing facilities for their needs. Several well
known labs (Sandia, Lawrence Livermore) rely on
huge clusters to do all types of complex analysis
that were unthinkable a couple of decades ago. While
the free BSD variants share the environment with
traditional UNIX systems, frequently used for such
computations, it was not common to find adequate
free software packages to carry complex calculations.
Eventually commercial versions of important math
related packages started to appear for the Linux
platform. Even when the big packages were distant,
the BSDs learned and adapted in resourceful ways:
Matlab and Mathematica, running under Linux emulation,
demanded functionality from the BSDs and NetBSD
implemented a signal trampoline to be able to run
AutoCAD with IRIX binary compatibility. A notable
project that was always available under a free
license was Berkeley's Spice circuit analysis
program, however it was an exception rather than
the rule. Even when the scientific community pressed
for a while to get other important tools like NASA's
FEA package Nastran under a free license, the
objective of being able to access and enhance open
scientific tools was elusive. About a decade ago
the situation started to improve: FreeBSD's ports
system started growing exponentially, first with a
high content in the math category, afterwards with
a CAD section and after sustained growth in those
categories a science section was created. This
growth was mostly pushed by Universities and their
research projects and in general are not well known
with respect to the commercial counterparts. I
started porting math/engineering code for FreeBSD
around 1996. Back then it was absolutely unthinkable
for a Mechanical Engineer to depend only on FreeBSD
for it's daily work. The situation nowadays is
different: there are some very high quality engineering
analysis packages like EDF's Code Aster, with more
than 12 years of professional development, that
just can't be ignored. A Finite Element package,
like Code Aster, can easily cost 5000 US$, is priced
according to the maximum problem size it can solve,
can require yearly licenses, and is rarely available
with source code. In NASTRAN's case the source code
is only available for US citizens under a yearly
fee. Free software does have serious limitations
though; just like in office applications there are
proprietary CAD formats or sometimes the package
simply doesn't have the required functionality.
Having the sources, of course, always has the
advantage of being able to implement (or pay for)
some specific functionality you might need. Many
commercial packages have been recently ported to
Linux, but even when they gain some of the advantages
of an open environment they still have yet another
limitation: they have been very slow to make use
of the multicored features of the new processors
in the market, a huge limitation now that the speed
war between processors has been limited by the
overheating problem. The objective of the talk is
to give an overview of several CAD/CAE packages
that have been made available recently as part of
FreeBSD's ports system and the decisions that were
made to port them. BRLCAD and Varkon are two CAD
utilities that made a transition from closed source
to an open environment and in the process in the
process of getting ported to BSD have gained greater
portability and general "bug" fixes critical for
their consolidation as usable and maintainable
projects. There are also some tricks that have not
been well documented: it is possible to enable
threads and some extra optimizations on some packages,
and it is also possible to replace the standard
BLAS library with the faster GOTO BLAS without
rebuilding the package. It is also possible to build
the packages optimized for a clustered environment,
but perhaps what is most interesting of all is how
all the packages interrelate with each other and
can turn FreeBSD into a complete enginering
environment. No OS distribution so far is offering
all the engineering specific utilities offered
through FreeBSD's ports system: from design to
visualization, passing through analysis FreeBSD is
becoming an option that can't be ignored, and best
of all, it is an effort that will benefit not only
FreeBSD but the wider audience.

to give me a subscription for several years to
FreeBSD's CD-ROM. Since then I've been on and off
porting software packages or fixing the bugs I have
caused while porting them. Of course there has
always been great respect for the other BSDs and
their wonderful license and while I've given up on
the idea of one day seeing a "UnifiedBSD" I am glad
to see different approaches sharing ideas in a

In this talk, we will discuss the past and present
history and the design principles of the OpenBSD
hardware sensors framework. Sensors framework
provides a unified interface for storing, registering
and accessing information about hardware monitoring
sensors. Sensor types include, but are not limited
to, temperature, voltage, fan RPM, time offset and
logical drive status. The framework spans
sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8),
ntpd(8), snmpd(8) and more than 67 drivers, ranging
from I2C temperature sensors and Super I/O hardware
monitors to IPMI, RAID and SCSI enclosures. Several
third-party tools are also available, for example,
a plug-in for Nagios and ports/sysutils/symon.
Originally based on some ideas from NetBSD, the
framework has sustained many improvements in OpenBSD,
and was ported and committed to FreeBSD and DragonFly
BSD.

The arrival of high CPU core density, with commodity
quad-core notebooks and 32-core servers, combined
with 10gbps networking have transformed network
design principles for operating systems. This talk
will describe changes in the FreeBSD 6.x, 7.x, and
forthcoming 8.x network stacks required to exploit
multiple cores and serve 10gbps networks. The goal
of the session will be to introduce the audience
to general strategies used to improve performance,
their rationales, and their impact on applications
and users:
- Introduction to the SMPng Project and the follow-on Netperf Project
- Workloads and performance measurement
- Efficient primitives to support modern network stacks
- Multi-core and cache-aware network memory allocator
- Fine-grained network stack locking
- Load-balancing and contention-avoidance across multiple CPUs
- CPU affinity for network stack data structures
- TCP performance enhancements including TSO, LRO, and TOE
- Zero-copy Berkely Packet Filter (BPF) buffers
- Direct network stack dispatch from interrupt handlers
- Multiple input and output queues

Martin Schuette has three main goals, defined by three
internet drafts to implement:
- TLS transport is the most obvious improvement: it
provides a reliable network transport with data encryption
and peer authentication. To make full use of this a
buffering mechanism to bridge temporary network errors
is implemented as well.
- Syslog-protocol extends the message format to use
a complete timestamp, include a fully qualified domain
name, and allow UTF-8 messages. It also offers a
structured data field to unambiguously encode application
dependent information.
- Syslog-sign will allow any syslog sender to digitally
sign its messages, so their integrity can be verified
later. This enable the detection of loss, deletion or
other manipulation syslog data after network transfer
or archiving on storage media.

Given the modern trend towards multi-core shared
memory multiprocessors, it is inconceivable for
production OS kernels not to be reentrant. The
typical approach for allowing multiple execution
contexts to simultaneously execute in kernel mode
has been to use fine-grained locking for synchronising
access to shared resources. While this technique
has been proven efficient, empirical evidence
suggests that the resulting locking rules tend to
be cumbersome even for the experienced kernel
programmer, leading to bugs that are hard to diagnose.
Moreover, scaling to more processors requires
extensive use of locks, which may impose unnecessary
locking overhead for small scale multiprocessor
systems. This talk will describe the typical approach
and then discuss the alternative approach taken in
the DragonFlyBSD network stack. We will give an
overview of the various protocol threads employed
for network I/O processing and the common-case code
paths for packet reception and transmission.
Additionally, we'll need to make a passing reference
to DragonFlyBSD's message passing model. This should
establish a baseline, allowing us to focus on the
recent work by the author to eliminate use of the
Big Giant Lock in the performance-critical paths
for the TCP and UDP protocols. The decision to
constrain this work on the two by far most widely-used
transport protocols was made in order to (a) limit
the amount of work necessary and (b) explore the
effectiveness of the approach on the cases that
matter at this point in time.

Many BSD-licensed strategies of various levels of
maturity exist to implement multiplicity, herein
defined as the introduction of plurality to
traditionally singular computing environments via
isolation, virtualization, or other method. For
example, the chroot utility introduces an additional
isolated root execution environment within that of
the host; or an emulator provides highly-isolated
virtual systems that can run complete native or
foreign operating systems. Motivations for multiplicity
vary, but a demonstrable desire exists for users
to obtain root or run a foreign binary or operating
system. We propose a hands-on survey of portable
and integrated BSD-licensed multiplicity strategies
applicable to the FreeBSD, OpenBSD, DragonFlyBSD
and NetBSD operating systems on the i386 architecture.
We will also address three oft-coupled disciplines:
software storage devices, the installation of
operating system and userlands in multiplicity
environments plus the management of select multiplicity
environments. Finally we will comment on each
strategies potential limits of isolation, compatibility,
independence and potential overhead in comparison
to traditional systems. Keywords: multiplicity,
virtualization, chroot, jail, hypervisor, xen,
compat.
Michael Dexter has used Unix systems since 1991 and
BSD-licensed multiplicity strategies for over five

Hello My name is Nick Barkas. I'm a master's student
studying scientific computing at Kungliga Tekniska
hgskolan (KTH) in Stockholm, Sweden. I have just
begun work on a Google Summer of Code project with
FreeBSD: Dynamic memory allocation for dirhash in
UFS2 . I would like to present my results from
this project at EuroBSDCon this year. This project
is very much a work in progress now so it is a bit
difficult to summarize what I would ultimately
present. I will try to describe an outline, though.
First I will give background information on dirhash:
an explanation of the directory data structure in
UFS2, how directory lookups in this structure
necessitate a linear search, and how dirhash speeds
these lookups up without having to change anything
about the directory data structure. Next I will
explain the current limitation that dirhash's maximum
memory use must be manually specified by administrators,
or left at a small conservative default of 2MB. I
will explain some different methods I will have
explored to try and make this maximum memory limit
dynamically increase and decrease as the system has
more or less free memory, and which method I will
have ultimately settled on and implemented. Then
I'll present some test results of performance of
operations on very large directories with and without
dynamic memory allocation enabled for dirhash. Next
I will talk about how speed gains from dirhash are
limited by the fact that the hash tables exist only
in memory and must be recreated after each system
boot, as big directories are scanned for the first
time, or even have to be recreated for a directory
that has not been scanned in some time if its dirhash
has been discarded to free memory. These problems
can be eliminated by using an on-disk index for
directory entries. I will talk about some of the
challenges of implementing on-disk indexing, such
as remaining backwards compatible with older versions
of UFS2 and interoperating properly with softupdates.
Then, if my SoC project has permitted me time to
work on this aspect of it, I will explain some
possible methods for adding directory indexing to
UFS2 that meets these challenges, and which of those
ideas I will have implemented. Finally I will present
results of some benchmarks on this filesystem with
indices, and compare to performance with dirhash,
and with no indices or dirhashes.

are distinct phases: requirements capture, design,
implementation, testing, delivery. Once a project
has moved on to the next phase there is no going
back. The end result is often a late project that
no-one wants anymore because the requirements have

The members of the BSD family have traditionally
prospered off the desktop, as operating systems on
servers and embedded systems. The advent of MacOS
X has marked a change, and moved the desktop more
into focus. Modern desktop systems create a richer
software landscape, with more diverse requirements,
than their server counterparts. User demands,
software package interdependencies and frequent
security issues result in a change rate that can
put a considerable load on the admin staff. Without
central management tools, previously identical
installations diverge quickly. This paper looks at
concepts and strategies for managing tens to hundreds
of modern, Unix-like desktop clients. The available
management tools range from simple, image-based
software distribution, mainly used for setting up
uniform clients, to "intelligent" rule-based engines
capable of search-and-replace operations on
configuration files. We will briefly compare their
properties and limitations, then take a closer look
at Radmind, a suite for file level administration
of Unix clients. Radmind has been in use in the
Institute of Telecommunication at Technische
Universitt Darmstadt for over three years, managing
NetBSD and Debian Linux clients in the labs as well
as faculty members' machines. We will explore the
Radmind suite's underlying concepts and functionality.
In order to see how the concept holds up, we will
discuss real-world scenarios from the system
life-cycle of Installation, configuration changes,
security updates, component updates, and system
upgrades.
Hauke Fath works as a systems administrator for the
Institut fr Nachrichtentechnik (telecommunication)
at Technische Universitt Darmstadt. He has been
using NetBSD since 1994, when he first booted a
NetBSD 1.0A kernel on a Macintosh SE/30. NetBSD
helped shaping his career by causing a slow drift
from application programmer's work towards systems
and network administration. Hauke Fath holds a MS

This paper discusses the NetBSD Power Management
Framework (PMF) and related changes to the kernel.
The outlined changes allow NetBSD to support essential
functions like suspend-to-RAM on most post-Y2K X86
machines. They are also the fundation for intelligent
handling of device activity by enabling devices
on-demand. This work is still progressing. Many of
the features will be available in the up-coming
NetBSD 5.0 release The NetBSD kernel is widely
regarded to be one of the cleanest and most portable
Operating System kernels available. For various
reasons it is also assumed that NetBSD only runs
well on older hardware. In the summer of 2006 Charles
Hannum, one of the founders of NetBSD, left with a
long mail mentioning as important issues the lack
of proper power management and suspendto- RAM
support. One year later, Jared D. McNeill posted a
plan for attacking this issue based on ideas derived
from the Windows Driver Model. This plan would
evolve into the new NetBSD Power Management Framework
(PMF for short).

The Aerospace Corporation operates a federally
funded research and development center in support
of national-security, civil and commercial space
programs. Many of our 2400+ engineers use a variety
of computing technologies to support their work.
Applications range from small models which are
easily handled by desktops to parameter studies
involving thousands of cpu hours and traditional,
large scale parallel codes such as computational
fluid dynamics and molecular modeling applications.
Our primary resources used to support these large
applications are computing clusters. Our current
primary cluster, the Fellowship cluster consists
of 352 dual-processor nodes with a total of 14xx
cores. Two additional clusters, beginning at 150
dual-processor nodes each are being constructed to
augment Fellowship. As in In any multiuser computing
environment with limited resources, user competition
for resources is a significant burden. Users want
everything they need to do their job, right now.
Unfortunately, other users may need those resources
at the same time. Thus, systems to arbitrate this
resource contention are necessary. On Fellowship
we have deployed the Sun Grid Engine scheduler which
scheduled batch jobs across the nodes. In the next
section we discuss the performance problems that
can occur when sharing resources in a high performance
computing cluster. We then discuss range of
possibilities to address these problems. We then
explain the solutions we are investigating and
describe our experiments with them. We then conclude
with a discussion of future work.

OS X and Windows XP/Vista/2000 clients. Tools have
been developed to create a central CA which enables
users to log in to a secure server and get their
customized client, certificates and configuration.
The NSIS installer is used to generate the customized
windows installers. Similar packages are generated
for the various Unix based clients. Additional
WWW/PHP based tools, have been developed to monitor
and log usage of the service, using standard graphs,
alarms for excessive use and a certificate revocation
mechanism. The system has been integrated into the
local identity management system (Kerberos/LDAP)
in order to authorize and authenticate users upon
initiation and per session usage. All code is Open

the reasons for this were clear: the UNIX kernel
was a simple entity. However, over time the kernel
has grown more and more complex. Currently, most
of the same functionality is available both in
userspace and the kernel, but under different names.
Examples include synchronization routines and
threading support. For instance, to lock a mutex
in the NetBSD kernel, the call is mutex_enter(),
while in userspace the routine which does exactly
the same thing is known as pthread_mutex_enter().
Taking another classic example, a BSD style OS has
malloc()/free() available both in userspace and the
kernel, but with different linkage (the kernel
malloc interface is currently being widely deprecated,
though). This imposes a completely arbitrary division
between the kernel and userspace. Most functionality
provided by an opearating system should be treated
as a service instead of explicitly pinning it down
as a userspace daemon or a kernel driver. Currently,
due to the arbitrarily difference in programming
interface names, functionality must be explicitly
ported between the kernel and userspace if it is
to run in one or the other environment. By unifying
the environments where possible, the arbitrary
division is weakened and porting between these
environments becomes simpler.
Antti Kantee has been a NetBSD developer for many
many moons. He has managed to work on quite a few
bits and pieces of a BSD system: userland utilities,
the pkgsrc packaging system, networking, virtual
memory, device drivers, hardware support and file
systems.

MP3 (1 byte, 57 minutes), OGG (1 byte, 57 minutes), PDF (1 byte, n pages)
This talk will present the different layers that
handle input, from the key that gets pressed or the
mouse motion to the applications, all the way through
the kernel drivers, X drivers and libraries, in the
case of the OpenBSD/NetBSD wscons driver and the
current and future X.Org server. It will cover stuff
like keyboard mappings, touch-screen calibration,
multi-pointer X or input coordinates transformations.
It will show some problems of current implementations
and try to show how current evolutions can solve
them.
Matthieu Herrb is maintaing X on OpenBSD. I've been
using X on various systems (SunOS, NetBSD, OpenBSD,
Mac OS X,...) since 1989. He has been a member of
the XFree86 Core Team for a short period in 2003
and is now a member of the X.Org Foundation BoD.
Matthieu Herrb works at LAAS a research laborarory
of the French National Research Agency (CNRS) both
on robotics and network security.

The FreeBSD Project is one of the oldest and most
successful open source operating system projects,
seeing wide deployment across the IT industry. From
the root name servers, to top tier ISPs, to core
router operating systems, to firewalls, to embedded
appliances, you can't use a networked computer for
ten minutes without using FreeBSD dozens of times.
Part of FreeBSD's reputation for quality and
reliability comes from the nature of its development
organization -- driven by a hundreds of highly
skilled volunteers, from high school students to
university professors. And unlike most open source
projects, the FreeBSD Project has developers who
have been working on the same source base for over
twenty years.
But how does this organization work? Who pays the
bandwidth bills, runs the web servers, writes the
documentation, writes the code, and calls the shots?
And how can developers in a dozen time zones reach
agreement on the time of day, let alone a kernel
architecture?
This presentation will attempt to provide, in 45
minutes, a brief if entertaining snapshot into what
makes FreeBSD run.

Nearly 10 years ago Kirk McKusick wrote a history
of the Berkeley Unix distributions for the O'Reilly
book "Open Sources: Voices from the Open Source
Revolution". We recommend you read his story,
entitled "Twenty Years of Berkeley Unix From
AT&T-Owned to Freely Redistributable" first, to see
how Kirk remembers how we got here. Sadly, since
it showed up in book form originally, this text has
probably not been read by enough people.
The USL(AT&T) vs BSDI/UCB court case settlement
documents were not public until recently; their
disclosure has made the facts more clear. But the
story of how three people decided to free the BSD
codebase of corporate pollution -- and release it
freely -- is more interesting than the lawsuit which
followed. Sure, a stupid lawsuit happened which
hindered the acceptance of the BSD code during a
critical period. But how did a bunch of guys go
through the effort of replacing so much AT&T code
in the first place? After all, companies had lots
of really evil lawyers back then too -- were they
not afraid?
After a decade of development, most of the AT&T
code had already been replaced by university
researchers and their associates. So Keith Bostic,
Mike Karels and Kirk McKusick (the main UCB CSRG
group) started going through the 4.3BSD codebase
to cleanse the rest. Keith, in particular, built a
ragtag team (in those days, USENIX conferences were
a gold mine for such team building) and led these
rebels to rewrite and replace all the Imperial AT&T
code, piece by piece, starting with the libraries
and userland programs. Anyone who helped only got
credit as a Contributor -- people like Chris Torek
and a cast of .. hundreds more.
Then Mike and Kirk purified the kernel. After a bit
more careful checking, this led to the release of
a clean tree called Net/2 which was given to the
world in June 1991 -- the largest dump of free
source code the world had ever received (for those
days -- not modern monsters like OpenOffice).
Some of these ragtags formed a company (BSDi) to
sell a production system based on this free code
base, and a year later Unix System Laboratories
(basically AT&T) sued BSDi and UCB. Eventually
AT&T lost and after a few trifling fixes (described
in the lawsuit documents) the codebase was free. A
few newer developments (and more free code) were
added, and released in June 1994 as 4.4BSD-Lite.
Just over 14 years later OpenBSD is releasing its
own 4.4 release (and for a lot less than $1000 per
copy).
The OpenBSD 4.4 release is dedicated to Keith Bostic,
Mike Karels, Kirk McKusick, and all of those who
contributed to making Net/2 and 4.4BSD-Lite free.

We are just plain tired of being lectured to by a
man who is a lot like Naomi Campbell.
In 1998 when a United Airlines plane was waiting
in the queue at Washington Dulles International
Airport for take-off to New Orleans (where a Usenix
conference was taking place), one man stood up from
his seat, demanded that they stop waiting in the
queue and be permitted to deplane. Even after orders
from the crew and a pilot from the cockpit he refused
to sit down. The plane exited the queue and returned
to the airport gangway. Security personnel ran onto
the plane and removed this man, Richard Stallman,
from the plane. After Richard was removed from the
plane, everyone else stayed onboard and continued
their journey to New Orleans. A few OpenBSD developers
were on that same plane, seated very closeby, so
we have an accurate story of the events.
This is the man who presumes that he should preach
to us about morality, freedom, and what is best for
us. He believes it is his God-given role to tell
us what is best for us, when he has shown that he
takes actions which are not best for everyone. He
prefers actions which he thinks are best for him
-- and him alone -- and then lies to the public.
Richard Stallman is no Spock.
We release our software in ways that are maximally
free. We remove all restrictions on use and
distribution, but leave a requirement to be known
as the authors. We follow a pattern of free source
code distribution that started in the mid-1980's
in Berkeley, from before Richard Stallman had any
powerful influence which he could use so falsely.
We have a development sub-tree called "ports". Our
"ports" tree builds software that is 'found on the
net' into packages that OpenBSD users can use more
easily. A scaffold of Makefiles and scripts
automatically fetch these pieces of software, apply
patches as required by OpenBSD, and then build them
into nice neat little tarballs. This is provided
as a convenience for users. The ports tree is
maintained by OpenBSD entirely separately from our
main source tree. Some of the software which is
fetched and compiled is not as free as we would
like, but what can we do. All the other operating
system projects make exactly the same decision, and
provide these same conveniences to their users.
Richard felt that this "ports tree" of ours made
OpenBSD non-free. He came to our mailing lists and
lectured to us specifically, yet he said nothing
to the many other vendors who do the same; many of
them donate to the FSF and perhaps that has something
to do with it. Meanwhile, Richard has personally
made sure that all the official GNU software --
including Emacs -- compiles and runs on Windows.
That man is a false leader. He is a hypocrite. There
may be some people who listen to him. But we don't
listen to people who do not follow their own stupid
rules.

Those of us who work on OpenBSD are often asked why
we do what we do. This song's lyrics express the
core motivations and goals which have remained
unchanged over the years - secure, free, reliable
software, that can be shared with anyone. Many other
projects purport to share these same goals, and
love to wrap themselves in a banner of "Open Source"
and "Free Software". Given how many projects there
are one would think it might be easy to stick to
those goals, but it doesn't seem to work out that
way. A variety of desires drag many projects away
from the ideals very quickly.
Much of any operating system's usability depends
on device support, and there are some very tempting
alternative ways to support devices available to
those who will surrender their moral code. A project
could compromise by entering into NDA agreements
with vendors, or including binary objects in the
operating system for which no source code exists,
or tying their users down with contract terms hidden
inside copyright notices. All of these choices
surrender some subset of the ideals, and we simply
will not do this. Sure, we care about getting devices
working, but not at the expense of our original
goals.
Of course since "free to share with anyone" is part
of our goals, we've been at the forefront of many
licensing and NDA issues, resulting in a good number
of successes. This success had led to much recognition
for the advancement of Free Software causes, but
has also led to other issues.
We fully admit that some BSD licensed software has
been taken and used by many commercial entities,
but contributions come back more often than people
seem to know, and when they do, they're always still
properly attributed to the original authors, and
given back in the same spirit that they were given
in the first place.
That's the best we can expect from companies. After
all, we make our stuff so free so that everyone can
benefit -- it remains a core goal; we really have
not strayed at all in 10 years. But we can expect
more from projects who talk about sharing -- such
as the various Linux projects.
Now rather than seeing us as friends who can
cooperatively improve all codebases, we are seen
as foes who oppose the GPL. The participants of
"the race" are being manipulated by the FSF and
their legal arm, the SFLC, for the FSF's aims,
rather than the goal of getting good source into
Linux (and all other code bases). We don't want
this to come off as some conspiracy theory, but we
simply urge those developers caution -- they should
ensure that the path they are being shown by those
who have positioned themselves as leaders is still
true. Run for yourself, not for their agenda.
The Race is there to be run, for ourselves, not for
others. We do what we do to run our own race, and
finish it the best we can. We don't rush off at
every distraction, or worry how this will affect
our image. We are here to have fun doing right.
OpenBSD 4.1 Release Song - Puffy Baba and the 40 Vendors

As developers of a free operating system, one of
our prime responsibilities is device support. No
matter how nice an operating system is, it remains
useless and unusable without solid support for a
wide percentage of the hardware that is available
on the market. It is therefore rather unsurprising
that more than half of our efforts focus on various
aspects relating to device support.
Most parts of the operating system (from low kernel,
through to libraries, all the way up to X, and then
even to applications) use fairly obvious interface
layers, where the "communication protocols" or
"argument passing" mechanisms (ie. APIs) can be
understood by any developer who takes the time to
read the free code. Device drivers pose an additional
and significant challenge though: because many
vendors refuse to document the exact behavior of
their devices. The devices are black boxes. And
often they are surprisingly weird, or even buggy.
When vendor documentation does not exist, the
development process can become extremely hairy.
Groups of developers have found themselves focused
for months at a time, figuring out the most simple
steps, simply because the hardware is a complete
mystery. Access to documentation can ease these
difficulties rapidly. However, getting access to
the chip documentation from vendors is ... almost
always a negotiation. If we had open access to
documentation, anyone would be able to see how
simple all these devices actually are, and device
driver development would flourish (and not just in
OpenBSD, either).
When we proceed into negotiations with vendors,
asking for documentation, our position is often
weak. One would assume that the modern market is
fair, and that selling chips would be the primary
focus of these vendors. But unfortunately a number
of behemoth software vendors have spent the last
10 or 20 years building political
hurdles against the smaller players.
A particularly nasty player in this regard has been
the Linux vendors and some Linux developers, who
have played along with an American corporate model
of requiring NDAs for chip documentation. This has
effectively put Linux into the club with Microsoft,
but has left all the other operating system communities
-- and their developers -- with much less available
clout for requesting documentation. In a more fair
world, the Linux vendors would work with us, and
the device driver support in all free operating
systems would be fantastic by now.
We only ask that users
help us in changing the political landscape.

The last 10 years, every 6 month period has (without
fail) resulted in an official OpenBSD release making
it to the FTP servers. But CDs are also manufactured,
which the project sells to continue our development
goals.
While tests of the release binaries are done by
developers around the world, Theo and some developers
from Calgary or Edmonton (such as Peter Valchev or
Bob Beck) test that the discs are full of (only)
correct code. Ty Semaka works for approximately two
months to design and draw artwork that will fit the
designated theme, and coordinates with his music
buddies to write and record a song that also matches
the theme.
Then the discs and all the artwork gets delivered
to the plant, so that they can be pressed in time
for an official release date.
This release, instead of bemoaning vendors or
organizations that try to make our task of writing
free software more difficult, we instead celebrate
the 10 years that we have been given (so far) to
write free software, express our themes in art, and
the 5 years that we have made music with a group
of talented musicians.
OpenBSD developers have been torturing each other
for years now with Humppa-style music, so this
release our users get a taste of this too. Sometimes
at hackathons you will hear the same songs being
played on multiple laptops, out of sync. It is under
such duress that much of our code gets written.
We feel like Pufferix and Bobilix delivering The
Three Discs of Freedom to those who want them
whenever the need arises, then returning to celebrate
the (unlocked) source tree with all the other
developers.
