Journaling FFS with WAPBL
NetBSD 5 is the first NetBSD release with a journaling
filesystem. This lecture introduces the structure
of the Fast File System, the modifications for WAPBL
and specific constraints of the implementation.
The Fast File System (FFS) has been used in the BSD
land for more than two decades. The original
implementation offered two operational modes:
- safe and slow (sync)
- unsafe and fast (async) One decade ago, Kirk
McKusick introduced the soft dependency mechanism
to offset the performance impact without risk of
mortal peril on the first crash. With the advent
of Terabyte hard disks, the need for a file system
check (fsck) after a crash becomes finally unacceptable.
Even a background fsck like supported on FreeBSD
consumes lots of CPU time and IO bandwidth.
Based on a donation from Wasabi Systems, Write Ahead
Physical Block Logging (WAPBL) provides journaling
for FFS with similar or better performance than
soft dependencies during normal operation. Recovery
time after crashes depends on the amount of outstanding
IO operations and normally takes a few seconds.
This lecture gives a short overview of FFS and the
consistency constraints for meta data updates. It
introduces the WAPBL changes, both in terms of the
on-disk format and the implementation in NetBSD.
Finally the implementation is compared to the design
of comparable file systems and specific issues of
and plans for the current implementation are
discussed.

Crypto Acceleration on FreeBSD
As more and more services on the internet become
cryptographically secured, the load of cryptography
on systems becomes heavier and heavier. Crypto
acceleration hardware is available in different
forms for different workloads. Embedded communications
processors from VIA and AMD have limited acceleration
facilities in silicon and various manufacturers
build hardware for accelerating secure web traffic
and IPSEC VPN tunnels.
This talk gives an overview of FreeBSD's crypto
framework in the kernel and how it can be used
together with OpenSSL to leverage acceleration
hardware. Some numbers will be presented to demonstrate
how acceleration can improve performance - and how
it can curiously bring a system to a grinding halt.
Philip originally started playing with crypto
acceleration when he saw the "crypto block" in one
of his Soekris boards. As usual, addiction was
instant and by the grace of the "you touch it, you
own it" principle, he has been fiddling the crypto
framework more than is good for him.

Multiple Passes of the FreeBSD Device Tree
The existing device driver framework in FreeBSD
works fairly well for many tasks. However, there
are a few problems that are not easily solved with
the current design. These problems include having
"real" device drivers for low-level hardware such
as clocks and interrupt controllers, proper resource
discovery and management, and allowing most drivers
to always probe and attach in an environment where
interrupts are enabled. I propose extending the
device driver framework to support multiple passes
over the device tree during boot. This would allow
certain classes of drivers to be attached earlier
and perform boot-time setup before other drivers
are probed and attached. This in turn can be used
to develop solutions to the earlier list of problems.

Isolating Cluster Jobs for Performance and Predictability
At The Aerospace Corporation, we run a large FreeBSD
based computing cluster to support engineering
applications. These applications come in all shapes,
sizes, and qualities of implementation. To support
them and our diverse userbase we have been searching
for ways to isolate jobs from one another in ways
that are more effective than Unix time sharing and
more fine grained than allocating whole nodes to
jobs.
In this talk we discuss the problem space and our
efforts so far. These efforts include implementation
of partial file systems virtualization and CPU
isolation using CPU sets.

Understanding and Tuning SCHED_ULE
With the advent of widespread SMP and multicore CPU
architectures it was necessary to implement a new
scheduler in the FreeBSD operating system. The
SCHEDULE scheduler was added for the 5 series of
FreeBSD releases and has now matured to the point
where it is the default scheduler in the 7.1 release.
While scheduling processes was a difficult enough
task in the uniprocessor world, moving to multiple
processors, and multiple cores, has significantly
increased the number of problems that await engineers
who wish to squeeze every last ounce of performance
out of their system. This talk will cover the basic
design of SCHEDULE and focus a great deal of attention
on how to tune the scheduler for different workloads,
using the sysctl interfaces that have been provided
for that purpose.
Understanding and tuning a scheduler used to be
done only by operating systems designers and perhaps
a small minority of engineers focusing on esoteric
high performance systems. With the advent of
widespread multi-processor and multi-core architectures
it has become necessary for more users and
administrators to decide how to tune their systems
for the best performance. The SCHEDULE scheduler
in FreeBSD provides a set of sysctl interfaces for
tuning the scheduler at run time, but in order to
use these interfaces effectively the scheduling
process must first be understood. This presentation
will give an overview of how SCHEDULE works and
then will show several examples of tuning the system
with the interfaces provided.
The goal of modifying the scheduler's parameters
is to change the overall performance of programs
on the system. One of the first problems presented
to the person who wants to tune the scheduler is
how to measure the effects of their changes. Simply
tweaking the parameters and hoping that that will
help is not going to lead to good results. In our
recent experiments we have used the top(1) program
to measure our results.

Results of a Security Assessment of the TCP and IP
protocols and Common implementation Strategies
Fernando Gont will present the results of security
assessment of the TCP and IP protocols carried out
on behalf of the United Kingdom's Centre for the
Protection of National Infrastructure (Centre for
the Protection of National Infrastructure). His
presentation will provide an overview of the
aforementioned project, and will describe some of
the new insights that were gained as a result of
this project. Additionally, it will provide an
overview of the state of affairs of the different
TCP/IP implementations found in BSD operating systems
with respect to the aforementioned issues.
During the last twenty years, many vulnerabilities
have been identified in the TCP/IP stacks of a
number of systems. The discovery of these vulnerabilities
led in most cases to reports being published by a
number of CSIRTs and vendors, which helped to raise
awareness about the threats and the best possible
mitigations known at the time the reports were
published. For some reason, much of the effort of
the security community on the Internet protocols
did not result in official documents (RFCs) being
issued by the organization in charge of the
standardization of the communication protocols in
use by the Internet: the Internet Engineering Task
Force (IETF). This basically led to a situation in
which "known" security problems have not always
been addressed by all vendors. In addition, in many
cases vendors have implemented quick "fixes" to the
identified vulnerabilities without a careful analysis
of their effectiveness and their impact on
interoperability. As a result, producing a secure
TCP/IP implementation nowadays is a very difficult
task, in large part because of the hard task of
identifying relevant documentation and differentiating
between that which provides correct advisory, and
that which provides misleading advisory based on
inaccurate or wrong assumptions. During 2006, the
United Kingdom's Centre for the Protection of
National Infrastructure embarked itself in an
ambitious and arduous project: performing a security
assessment of the TCP and IP protocols. The project
did not limit itself to an analysis of the relevant
IETF specifications, but also included an analysis
of common implementation strategies found in the
most popular TCP and IP implementations. The result
of the project was a set of documents which identifies
possible threats for the TCP and IP protocols and,
where possible, proposes counter-measures to mitigate
the identified threats. This presentation will will
describe some of the new insights that were gained
as a result of this project. Additionally, it will
provide an overview of the state of affairs of the
different TCP/IP implementations found in BSD
operating systems.

Implementation of TARGET_MODE applications
How we used TARGET_MODE in the kernel to create and
interesting product
This presentation will cover a real world implementation
of the TARGET_MODE infrastructure in the kernel
(stable/6). Topics to include: drivers used (isp,
aic7xxx, firewire). scsi_target userland code vs
kernel drivers missing drivers (4/8G isp support,
iSCSI target)
Target Mode describes a feature within certain
drivers that allows a FreeBSD system to emulate a
Target in the SCSI sense of the word. By recompiling
your kernel with this feature enabled, it permits
one to turn a FreeBSD system into an external hard
disk. This feature of the FreeBSD kernel provides
many interesting implementations and is highly
desirable to many organizations whom run FreeBSD
as their platform.
I have been tasked with the maintenance of a
proprietary target driver that interfaces with the
FreeBSD kernel to do offsite data mirroring at the
block level. This talk will discuss the implementation
of that kernel mode driver and the process my
employer went through to implement a robust and
flexible appliance.
Since I took over the implementation, we have
implemented U160 SCSI(via aic7xxx), 2G Fibre
Channel(via isp) and Firewire 400 (via sbp_targ).
Each driver has it's own subtleties and requirements.
I personally enhanced the existing Firewire target
driver and was able to get some interesting results.
I hope to demonstrate a functional Firewire 400/800
target and show how useful this application can be
for the embedded space. Also, I wish to demonstrate
the need for iSCSI. USB and 4/8G Fibre Channel
target implementations that use the TARGET_MODE
infrastructure that is currently in place to allow
others to expand their various interface types.
The presentation should consist of a high level
overview, followed by detailed implementation
instructions with regards to the Firewire implementation
and finish up with a hands-on demonstration with a
FreeBSD PC flipped into TARGET_MODE and a Mac.

Central to the toolbox is the OpenBSD PF packet
filter, supplemented with tools that interact with
it. Whether you are a greybeard looking for ways
to optimize your setups or a greenhorn just starting
out, this session will give you valuable insight
into the inner life of your network and provide
pointers to how to use that knowledge to build the
network you need. The session will also offer some
fresh information on changes introduced in OpenBSD
4.5, the most recent version of PF and OpenBSD. The
tutorial is loosely based on Hansteen's recent book,
/The Book of PF/ (No Starch Press), with updates
and adaptations based on developments since the
book's publication date.

Remote and mass management of systems with finstall
Automated management on a largish scale
An important part of the "finstall" project, created
as a graphical installer for FreeBSD, is a configuration
server that can be used to remotely administer and
configure arbitrary systems. It allows for remote
scripting of administration tasks and is flexible
enough to support complete reconfiguration of running
systems.
The finstall project has two major parts - the
front-end and the back-end. The front-end is just
a GUI allowing the users to install the system in
a convenient way. The back-end is a network-enabled
XML-RPC server that is used by the front-end to
perform its tasks. It can be used as a stand-alone
configuration daemon. This talk will describe a way
to make use of this property of finstall to remotely
manage large groups of systems.

scrypt: A new key derivation function
Doing our best to thwart TLAs armed with ASICs
Password-based key derivation functions are used
for two primary purposes: First, to hash passwords
so that an attacker who gains access to a password
file does not immediately possess the passwords
contained therewithin; and second, to generate
cryptographic keys to be used for encrypting or
authenticating data.
In both cases, if passwords do not have sufficient
entropy, an attacker with the relevant data can
perform a brute force attack, hashing potential
passwords repeatedly until the correct key is found.
While commonly used key derivation functions, such
as Kamp's iterated MD5, Provos and Mazieres' bcrypt,
and RSA Laboratories' PBKDF1 and PBKDF2 make an
attempt to increase the difficulty of brute-force
attacks, they all require very little memory, making
them ideally suited to attack by custom hardware.
In this talk, I will introduce the concepts of
memory-hard and sequential memory-hard functions,
and argue that key derivation functions should be
sequential memory-hard. I will present a key
derivation function which, subject to common
assumptions about cryptographic hash functions, is
provably sequential memory-hard, and a variation
which appears to be stronger (but not provably so).
Finally, I will provide some estimates of the cost
of performing brute force attacks on a variety of
password strengths and key derivation functions.

Students will learn the basic data structures and
APIs necessary to implement a network driver in

be applied to other BSDs, and likely to other
embedded and UNIX like systems while being specific
enough that given a device and a manual the student
should be able to develop a working driver on their

This session will start with an introduction to the
project and its common uses, which have expanded
considerably beyond firewalling. We will cover much
of the new functionality coming in the 2.0 release,
which contains significant enhancements to nearly
every portion of the system as well as numerous new
features.
While the primary function of the project is a
firewalling and routing platform, with changes
coming in pfSense 2.0, it has also become an appliance
building framework enabling the creation of customized
special purpose appliances. The m0n0wall code where
pfSense originated has proved popular for this
purpose, with AskoziaPBX and FreeNAS also based
upon it, in addition to a number of commercial
solutions. The goal of this appliance building
framework is to enable creation of projects such
as these without having to fork and maintain another
code base. The existing appliances, including a DNS
server using TinyDNS, VoIP with FreeSWITCH, and
others will be discussed. For those interested in
creating appliances, an overview of the process
will be provided along with references for additional
information.

PC-BSD - Making FreeBSD on the desktop a reality
FreeBSD on the Desktop
While FreeBSD is a all-around great operating system,
it is greatly lagging behind in desktop appeal. Why
is this? In this talk, we will take a look at some
of the desktop drawbacks of FreeBSD, and how are
are attempting to fix them through PC-BSD.
FreeBSD has a reputation for its rock-solid
reliability, and top-notch performance in the server
world, but is noticeably absent when it comes to
the vast market of desktop computing. Why is this?
FreeBSD offers many, if not almost all of the same
open-source packages and software that can be found
in the more popular Linux desktop distributions,
yet even with the speed and reliability FreeBSD
offers, a relative few number of users are deploying
it on their desktops.
In this presentation we will take a look at some
of the reasons why FreeBSD has not been as widely
adopted in the desktop market as it has on the
server side. Several of the desktop weaknesses of
FreeBSD will be shown, along with how we are trying
to fix these short-comings through a desktop-centric
version of FreeBSD, known as PC-BSD. We will also
take a look at the package management system employed
by all open-source operating systems alike, and
some of the pitfalls it brings, which may hinder
widespread desktop adoption.

Detecting TCP regressions with tcpdiff
Determining if a TCP stack is working correctly is
hard. The tcpdiff project aims for a simpler goal:
To automatically detect differences in TCP behavior
between different versions of an operating system
and display those differences in an easy to understand
format. The value judgement of whether a certain
change between version X and Y of a TCP stack is
good or bad will be left to human eyes.

The initial version of tcpdiff presented at NYCBSDCon
2008 demonstrated that it could be used to detect
at least two major TCP bugs that were introduced
into FreeBSD in the past few years. The work from
that presentation can be viewed at
http://www.silby.com/nycbsdcon08/.
For BSDCan 2009, I hope to fix a number of bugs in
tcpdiff, make it easier to use, set up nightly tests
of FreeBSD, and improve it so that additional known
bugs can be detected. Additionally, I plan to run
it on OSes other than FreeBSD.

Quiet Computing with BSD
Programming system hardware monitors for quiet computing
In this talk, we will present a detailed overview
of the features and common problems of microprocessor
system hardware monitors as they relate to the topic
of silent computing. In a nutshell, the topic of
programmable fan control will be explored.
Silent computing is an important subject as its
practice reduces the amount of unnecessary stress
and improves the motivation of the workforce, at
home and in the office.
Attendees will gain knowledge on how to effectively
programme the chips to minimise fan noise and avoid
system failure or shutdown during temperature
fluctuations, as well as some basic principles
regarding quiet computing.
Shortly before the talk, a patch for programming
the most popular chips (like those from Winbond)
will be released for the OpenBSD operating system,
although the talk itself will be more specific to
the microprocessor system hardware monitors themselves,
as opposed to the interfacing with thereof in modern
operating systems like OpenBSD, NetBSD, DragonFly
BSD and FreeBSD.

Improving the FreeBSD TCP Implementation.
An update on all things TCP in FreeBSD and how they
affect you.
My involvement in improving the FreeBSD TCP stack
has continued this past year, with much of the work
targeted at FreeBSD 8. This talk will cover what
these changes entail, why they are of interest to
the FreeBSD community and how they help to improve
our TCP implementation.
It has been a busy year since attending my inaugural
BSDCan in 2008, where I talked about some of my
work with TCP in FreeBSD.
I have continued the work on TCP analysis/debugging
tools and integrating modular congestion control
into FreeBSD as part of the NewTCP research project.
I will provide a progress update on this work.
Additionally, a grant win from the FreeBSD Foundation
to undertake a project titled "Improving the FreeBSD
TCP Implementation" at Swinburne University's Centre
for Advanced Internet Architectures has been
progressing well. The project focuses on bringing
TCP Appropriate Byte Counting (RFC 3465), reassembly
queue auto-tuning and integration of low-level
analysis/debugging tools to the base system, all
of which I will also discuss.

GEOM based disk schedulers for FreeBSD
The high cost of seek operations makes the throughput
of disk devices very sensitive to the offered
workload. A disk scheduler can then help reorder
requests to improve the overall throughput of the
device, or improve the service guarantees for
individual users, or both.
Research results in recent years have introduced,
and proven the effectiveness of, a technique called
"anticipatory scheduling". The basic idea behind
this technique is that, in some cases, requests
that cause a seek should not be served immediately;
instead, the scheduler should wait for a short
period of time in case other requests arrive that
do not require a seek to be served. With many common
workloads, dominated by sequential synchronous
requests, the potential loss of throughput caused
by the disk idling times is more than balanced by
the overall reduction of seeks.
While a fair amount of research on disk scheduling
has been conducted on FreeBSD, the results were
never integrated in the OS, perhaps because the
various prototype implementations were very
device-specific and operated within the device
drivers. Ironically, anticipatory schedulers are
instead a standard part of Linux kernels.
This talk has two major contributions:
First, we will show how, thanks to the flexibility
of the GEOM architecture, an anticipatory disk
scheduling framework has been implemented in FreeBSD
with little or no modification to a GENERIC kernel.
While these schedulers operate slightly above the
layer where one would naturally put a scheduler,
they can still achieve substantial performance
improvements over the standard disk scheduler; in
particular, even the simplest anticipatory schedulers
can prevent the complete trashing of the disk
performance that often occurs in presence of multiple
processes accessing the disk.
Secondly, we will discuss how the basic anticipatory
scheduling technique can be used not only to improve
the overall throughput of the disk, but also to
give service guarantees to individual disk clients,
a feature that is extremely important in practice
e.g., when serving applications with pseudo-real-time
constraints such as audio or video streaming ones.
A prototype implementation of the scheduler that
will be covered in the presentation is available

Tracking FreeBSD in a commercial Environment
How to stay current while staying sane
The FreeBSD project publishes two lines of source
code: current and stable. All changes must first
be committed to current and then are merged into
stable. Commercial organizations wishing to use
FreeBSD in their products must be aware of this
policy. Four different strategies have developed
for tracking FreeBSD over time. A company can choose
to run only unmodified release versions of FreeBSD.
A company may choose to import FreeBSD's sources
once and then never merge newer versions. A company
can choose to import each new stable branch as it
is created, adding its own changes to that branch,
as well as integrating new versions from FreeBSD
from time to time. A company can track FreeBSD's
current branch, adding to it their changes as well
as newer FreeBSD changes. Which method a company
chooses depends on the needs of the company. These
methods are explored in detail, and their advantages
and disadvantages are discussed. Tracking FreeBSD's
ports and packages is not discussed.
Companies building products based upon FreeBSD have
many choices in how to use the projects sources and
binaries. The choices range from using unmodified
binaries from FreeBSD's releases, to tracking modify
FreeBSD heavily and tracking FreeBSD's evolution
in a merged tree. Some companies may only need to
maintain a stable version of FreeBSD with more bug
fixes or customizations than the FreeBSD project
wishes to place in that branch. Some companies also
wish to contribute some subset of their changes
back to the FreeBSD project.
FreeBSD provides an excellent base technology with
which to base products. It is a proven leader in
performance, reliability and scalability. The
technology also offers a very business friendly
license that allows companies to pick and choose
which changes they wish to contribute to the community
rather than forcing all changes to be contributed
back, or attaching other undesirable license
conditions to the code.
However, the FreeBSD project does not focus on
integration of its technology into customized
commercial products. Instead, the project focuses
on producing a good, reliable, fast and scalable
operating system and associated packages. The project
maintains two lines of development. A current branch,
where the main development of the project takes
place, and a stable branch which is managed for
stability and reliability. While the project maintains
documentation on the system, including its development
model, relatively little guidance has been given
to companies in how to integrate FreeBSD into their
products with a minimum of trouble.
Developing a sensible strategy to deal with both
these portions of FreeBSD requires careful planning
and analysis. FreeBSD's lack of guidelines to
companies leaves it up to them to develop a strategy.
FreeBSD's development model differs from some of
the other Free and Open Source projects. People
familiar with those systems often discover that
methods that were well suited to them may not work
as well with FreeBSD's development model. These two
issues cause many companies to make poor decisions
without understanding the problems that lie in their
future.
Very little formal guidance exists for companies
wishing to integrate FreeBSD into their products.
Some email threads can be located via a Google
search that could help companies, but many of them
are full of contradictory information, and it is
very disorganized. While the information about the
FreeBSD development process is in the FreeBSD
handbook, the implications of that process for
companies integrating FreeBSD into their products
are not discussed.

that are more effective than Unix time sharing and
more fine grained than allocating whole nodes to
jobs. In this paper we discuss the problem space

Ineffective concurrency mechanisms in an operating
system can lead to low performance in both single

involved with attempting overly invasive kernel
changes have made it difficult in the past to
implement new and innovative concurrency systems.
This paper describes the rationale behind interfaces
in the DragonFly BSD operating system intended to
provide high performance and scalability on
multiprocessor architectures. Using a lock-free
processor centric approach, DragonFly BSD has
developed a unique thread system with the potential
for excellent scalability.

In NetBSD and OpenBSD, user-land process and
process-context isolation is limited to credential
cross-checks, file-system chroot and explicit
systrace/kauth applications. I'll demonstrate a
working mechanism of isolated process trees in
branched OpenBSD-4.4 and NetBSD-5.0-beta kernels
where an isolated process is started by a system
call similar to fork; following that, the child
process and its descendants execute in a context
isolated from the caller. This system is the continued
work of "mult" -- first prototyped in a branched
NetBSD-3.1 kernel and isolating all system resources
-- pared down to a lightweight, auditable patch of
process-only separation for both OpenBSD and NetBSD.
I specifically address solutions to performance
issues and mechanism design with an eye toward more
resources being isolated in the future.

Speaker Bio
Victor Duchovni trained in mathematics, switched
tracks to CS in 1980s leaving Princeton with a
master`s degree in mathematics and newly acquired
skills in Unix system administration and system
programming. In 1990 moved to Lehman Brothers,
worked on system management tooling, and network
engineering. Ported "Moira" from MIT to Lehman,
built efficient build systems that predated (and
partly inspired) Jumpstart. In 1994 joined ESM to
market "CMDB" tools to enterprise users, but this
did not pan out, in the mean time learned Tcl, and
contributed bunch of patches to the 7.x early 8.x
TCL releases. In 1997 returned to New York, working
in IT Security at Morgan Stanley since late 1999.
At Morgan Stanley, developed a hobby in perimeter
email security, becoming an active Postfix user and
very soon contributor in May of 2001. In addition
to many smaller feature improvements, contributed
initial implementation of SMTP connection caching,
overhauled and currently maintain LDAP and TLS
support. Made significant design contributions to
queue manager in collaboration with Wietse and
Patrik Raq. In 2.6 contributing support for TLS EC
ciphers and multi-instance management tooling,
ideally also TLS SNI if time permits.

A sneak peak into the FreeBSD development process.
Warning 2 hours! filmed over 2 days.
(The schedule worked out was optimistic to say the
least but it's still looking ok...)
Marko Zec and Julian Elischer report back to the
developers at BSDCan on the progress on virtualizing
the network stack in FreeBSD. This has been a long
term project but at the time of this recording was
just reaching the point of feasibility. In this
video you can see some of the dynamics of the group
as developers become familiar with the project and
discussions take place regarding such things as
maintainability, ABI compatibility, and even what
to call the feature. In this video you can see the
decision being made by a "quorum" of developers to
take this project mainstream.
The sound is less that perfect, but it's what we have.
This is a montage of 3 video sources, one of which
is a lower resolution, but at times it was the only
camera capturing the action. (the other ran out of
tape for a while)
Thanks to Ed Maste for the added footage.
I will be doing more editing later and will be
substituting in better footage in some places.

Ogg version (4.4 Mb, 3 minutes 5 seconds), MP3 version (5.6 Mb, 3 minutes 5 seconds)
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.

Many modern CPUs provide on chip counters for
performance events such as retiring instructions
and cache misses. The hwpmc driver and libraries
in FreeBSD give systems administrators and programmers
access to APIs which make it possible to measure
performance without modifying source code and with
minimal intrusion into application execution. This
talk will be a brief introduction to HWPMC, and how
to use it.

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.

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.
Martin Schuette is a student of computer science in
Potsdam, Germany, and has been working as a part-time
system administrator for BSD servers since 2004.
In 2007 Martin Schuette already gave a talk on Syslog

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

years. He is the Program Manager at the BSD Fund

The Google Summer of Code is a program designed to
provide students with real world experience
contributing to open source projects during the
summer break in university studies. Each year Google
selects a number of open source projects to act as
mentoring organizations. Students are invited to
submit project proposals for the open source projects
that are most interesting to them. FreeBSD was one
of the projects selected to participate in the
inaugural Summer of Code in 2005 and we have
participated each year since then. Over the past 4
years a total of 79 students have participated in
the program and it has become a very significant
source of new committers to FreeBSD. This talk will
examine in detail the selection criteria for projects,
the impact that successful projects have had, and
some suggestions for how we can better leverage
this program in the future.

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.

fell in love with the idea of being able to install
a complete version of UNIX from the net with just

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 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.

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.

helped shaping his career by causing a slow drift

simultaneous users. The system supports, Linux, Mac
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

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

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.

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.

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.

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.

integrate well with the available typesetters.
Edd Barrett os a student from the UK, currently on
"placement year" as a systems administrator for
Bournemouth University. Open Source *NIX has been
his platform of choice for many years and he has
been using OpenBSD for about 3 years now, simply
because it is small, clean, correct and secure.
Just recently he has started developing things I
want or need for OpenBSD.

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).

ABSD/UNIX operating system is traditionally split
into two pieces: the kernel and userspace. Historically
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.

Two tools which have become the norm in Linux- and
Unix-based environments are SSH for secure
communications, and sudo for performing administrative
tasks. These are independent programs with substantially
different purposes, but they are often used in
conjunction. In this talk, I describe a flaw in
their interaction, and then present our solution
called public-key sudo.
Public-key sudo is an extension to the sudo
authentication mechanism which allows for public
key authentication using the SSH public key framework.
I describe our implementation of a generic SSH
authentication module and the sudo modifications
required to use this module.

Configuration Management with Cfengine
Cfengine is a policy-based configuration management
system. Its primary function is to provide automated
configuration and maintenance of computers, from a
policy specification.
The cfengine project was started in 1993 as a
reaction to the complexity and non-portability of
shell scripting for Unix configuration management,
and continues today. The aim was to absorb frequently
used coding paradigms into a declarative, domain-specific
language that would offer self-documenting
configuration.

Steven Kreuzer has been working with Open Source
technologies since as long as he can remember,
starting out with a 486 salvaged from a dumpster

pfSense Tutorial
From Zero to Hero with pfSense
pfSense is a free, open source customized distribution
of FreeBSD tailored for use as a firewall and router.
In addition to being a powerful, flexible firewalling
and routing platform, it includes a long list of
related features and a package system allowing
further expandability without adding bloat and
potential security vulnerabilities to the base
distribution. pfSense is a popular project with
more than 1 million downloads since its inception,
and proven in countless installations ranging from
small home networks protecting a PC and an Xbox to
large corporations, universities and other organizations
protecting thousands of network devices.
This tutorial is being presented by the founders
of the pfSense project, Chris Buechler and Scott
Ullrich.
The session will start with an introduction to the
project, hardware sizing and selection, installation,
firewalling concepts and basic configuration, and
continue to cover all the most popular features of
the system. Common usage scenarios, deployment
considerations, step by step configuration guidance,
and best practices will be covered for each feature.
Most configurations will be demonstrated in a live
lab environment.
Attendees are assumed to have basic knowledge of
TCP/IP and firewalling concepts, however no in-depth
knowledge in these areas or prior knowledge of
pfSense or FreeBSD is necessary.

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.

Measured (almost) does Air Traffic Control
Monitoring weird hardware reliably
The new Danish Air Traffic Control system, CASIMO,
prompted the development on a modular and general
software platform for data collection, control and
monitoring of "weird hardware" of all sorts.
The talk will present the "measured" daemon, and
detail some of the uses it has been put to, as an,
admittedly peripheral, component of the ATC system.
Many "SCADA" systems suffer from lack of usable
interfaces for external access to the data. Measured
takes the opposite point of view and makes real-time
situation available, and accepts control instructions
as ASCII text stream over TCP connections. Several
examples of how this can be used will be demonstrated.
Measured will run on any FreeBSD system, but has
not been ported to other UNIX variants yet, and it
is perfect for that "intelligent house" project of
yours.
I believe I gave a WIP presentation of this about
two years ago.

FreeBSD/mips
Embedding FreeBSD
FreeBSD now runs on the MIPS platform. FreeBSD/mips
supports MIPS-32 and MIPS-64 targets, including SMP
for multicore support.
FreeBSD/mips is targeted at the embedded MIPS
marketplace. FreeBSD has run on the MIPS platform
for many years. Juniper ported FreeBSD to the Mips
platform in the late 1990's. However, concern about
intellectual property issues kept Juniper from
contributing the port back to FreeBSD until recently.
The contributed port was a 64-bit mips port.
In the mean time, many efforts were made to bring
FreeBSD to the mips platform. The first substantial
effort to bring FreeBSD to the Mips platform was
done by Juli Mallet. This effort made it to single
user, but never further than that. This effort was
abandoned due to a change in Juli's life. The port
languished.
Two years ago at BSDcan, as my involvement with
FreeBSD/arm was growing, I tried to rally the troops
into doing a FreeBSD/mips port. My efforts resulted
in what has been commonly called the "mips2" effort.
The name comes from the choice of //depot/projects/mips2
to host the work in perforce. A number of people
worked on the earliest versions of the port, but
it too languished and seemed destined to suffer the
same fate as earlier efforts. Then, two individuals
stood up and started working on the port. Wojciech
A. Koszek and Oleksandr Tymoshenko pulled in code
from the prior efforts. Through their efforts of
stabilizing this code, the port to the single user
stage and ported it to three different platforms.
Others ported it to a few more. Snapshots of this
work were released from time to time.
Cavium Networks picked up one of these snapshots
and ported it to their multicore mips64 network
processor. Cavium has kindly donated much of their
work to the comminuty.
In December, I started at Cisco systems. My first
job was to merge all the divergent variants of
FreeBSD/mips and get it into shape to push into the
tree. With luck, this should be in the tree before
I give my talk.
In parallel to this, other advances in the embedded
support for FreeBSD have been happening as well.
I'll talk about new device drivers, new subsystems,
and new build tools that help to support the embedded
developer.

Building self-contained PBIs from Ports (Automagically)
Creating a self-contained application from the ports tree
PC-BSD provides a user-friendly desktop experience,
for experts and casual users alike. PC-BSD is 100%
FreeBSD under the hood, while providing desktop
essentials, such as a graphical installation system,
point-n-click package-management using the PBI
system, and easy to use system management tools;
All integrated into an easy to use K Desktop
Environment (KDE).
The PBI (Push Button Installer) format is the
cornerstone of the PC-BSD desktop, which allows
users to install applications in a self-contained
format, free from dependency problems, and compile
issues that stop most casual users from desktop
adoption. The PBI format also provides power and
flexibility in user interaction, and scripting
support, which allows applications to be fine-tuned
to the best possible user experience.
This talk would go over in some detail our new PBI
building system, which converts a FreeBSD port,
such as FireFox, into a standalone self-contained
PBI installer for PC-BSD desktops.
The presentation will be divided into two main sections:
The Push Button Installer (PBI) Format
- The basics of the PBI format
- The PBI format construction
- Add & Remove scripting support within PBI
Building PBIs from Ports "Auto-magically"
- The PBI build server & standalone software

An Open Source Enterprise VPN Solution with OpenVPN and OpenBSD
Solving the problem
At Appalachian State University, we utilize an open
source VPN to allow faculty, staff and vendors
secure access to Appalachian State University's
internal network from any location that has an
Internet connection. To implement our virtual private
network project, we needed a secure VPN that is
flexible enough to work with our existing network
registration and LDAP authentication systems, has
simple client installation, is redundant, allows
multiple VPN server instances for special site-to-site
tunnels and unique configurations, and can run on
multiple platforms. Using OpenVPN running on OpenBSD,
we met those requirements and added a distributed
administration system that allows select users to
allow VPN access to specific computers for external
users and vendors without requiring intervention
from our network or security personnel. Our
presentation will start with a quick overview of
OpenVPN and OpenBSD and then detail the specifics
of our VPN implementation.
Dissatisfied with IPSec for road warrior VPN usage
we went looking for a better solution. We had hopped
that we could find a solution that would run on
multiple platforms, was flexible and worked well.
We found OpenVPN and have been pleased. Initially
we ran it on RHEL. We migrated to OpenBSD for pf
functionality and general security concerns. ...and
because we like OpenBSD.
Our presentation will focus on the specifics of our
VPN implementation. We will quickly cover the basics
of OpenVPN and the most used features of OpenBSD.
Moving along we will cover multiple authentication
methods, redundancy, running multiple instances,
integration with our netreg system, how pf has
extended functionality, embedding in appliances,
and client configuration. The system has proven
helpful with providing vendor access where needed
and we'll cover this aspect as well. Time permitting
we will cover current enhancement efforts and future
plans.
OpenVPN has been called the "Swiss army knife" of
VPN solutions. We hope our presentation leaves
participants with that feeling.

"finstall" - the new FreeBSD installer
A graphical installer for FreeBSD
The "finstall" project, sponsored by Google as a
Summer of Code 2007 project, is an attempt to create
a user-friendly graphical installer for FreeBSD,
with enough strong technical features to appeal to
the more professional users. A long term goal for
it is to be a replacement for sysinstall, and as
such should support almost all of the features
present in sysinstall, as well as add support for
new FreeBSD features such as GEOM, ZFS, etc. This
talk will describe the architecture of "finstall"
and focus on its lesser known features such as
remote installation.
"finstall" is funded by Google SoC as a possible
long-term replacement for sysinstall, as a "LiveCD"
with the whole FreeBSD base system on the CD, with
X11 and XFCE4 GUI. In the talk I intend to describe
what I did so far, and what are the future plans
for it. This includes the installer GUI, the backend
(which has the potential to become a generic FreeBSD
configuration backend) and the assorted tools
developed for finstall ("LiveCD" creation scripts).
More information on finstall can be found here:

Introduction to Debugging the FreeBSD Kernel
Just like every other piece of software, the FreeBSD
kernel has bugs. Debugging a kernel is a bit different
from debugging a userland program as there is nothing
underneath the kernel to provide debugging facilities
such as ptrace() or procfs. This paper will give a
brief overview of some of the tools available for
investigating bugs in the FreeBSD kernel. It will
cover the in-kernel debugger DDB and the external
debugger kgdb which is used to perform post-mortem
analysis on kernel crash dumps.
Introduction to Debugging the FreeBSD Kernel
- Basic crash messages, what a crash looks like
- typical panic() invocation
- page fault example
- "live" debugging with DDB
- stack traces
- ps
- deadlock examples
- show lockchain
- show sleepchain
- Adding new DDB commands
- KGDB
- inspecting processes and threads
- working with kernel modules
- using scripts to extend
- examining crashdumps using utilities
- debugging strategies
- kernel crashes
- system hangs

What Not To Do When Writing Network Applications
The lessons learnt working with not-so-high-performance network applications
This talk will look at issues which face the modern
network application developer, from the point of
view of poorly-designed examples. This will cover
internal code structure and dataflow, interaction
with the TCP stack, IO scheduling in high and low
latency environments and high-availability
considerations. In essence, this presentation should
be seen as a checklist of what not to do when writing
network applications.
Plenty of examples of well designed network
applications exist in the open and closed source
world today. Unfortunately there are just as many
examples of fast network applications as there are
"fast but workload specific"; sometimes failing
miserably in handling the general case. This may
be due to explicit design (eg Varnish) but many are
simply due to the designer not fully appreciating
the wide variance in "networks" - and their network
application degrades ungracefully when under duress.
My aim in this presentation is to touch on a wide
number of issues which face network application
programmers - most of which seem not "application
related" to the newcomer - such as including
pipelining into network communication, managing a
balance between accepting new requests and servicing
existing requests, or providing back-pressure to a
L4 loadbalancer in case of traffic bursts. Various
schemes for working with these issues will be
presented, and hopefully participants will walk
away with more of an understanding about how the
network, application and operating systems interact.

Porting FreeBSD/ARM to Marvell Orion System-On-Chip
This talk covers the development work on porting
the FreeBSD/ARM to Marvell Orion family of highly
integrated chips.
ARM architecture is widely adopted in the embedded
devices, and since the architecture can be licensed,
many implementation variations exist: Orion is a
derivative compliant with the ARMv5TE definition,
it provides a rich set of on-chip peripherals.
Present state of the FreeBSD support for ARM is
explained, areas for improvement highlighted and
its overall shape and condition presented.
The main discussion covers scope of the Orion port
(what integrated peripherals required new development,
what was adapted from existing code base); design
decisions are explained for the most critical items,
and implementation details revealed.
Summary notes are given on general porting methodology,
debugging techniques and difficulties encountered
during such undertaking.

DTrace for FreeBSD
What on earth is that system doing?!
DTrace is a comprehensive dynamic tracing facility
originally developed for Solaris that can be used
by administrators and developers on live production
systems to examine the behavior of both user programs
and of the operating system itself. DTrace enables
users to explore their system to understand how it
works, track down performance problems across many
layers of software, or locate the cause of aberrant
behavior. DTrace lets users create their own custom
programs to dynamically instrument the system and
provide immediate, concise answers to arbitrary
questions you can formulate using the DTrace D
programming language.
This talk discusses the port of the DTrace facility
to FreeBSD and demonstrates examples on a live
FreeBSD system.
- Introduction to the D language - probes, predicates and actions.
- dtrace(8) and libdtrace - the userland side of the DTrace story.
- The DTrace kernel module, it's ioctl interface to userland and the provider infrastructure in the kernel.
- DTrace kernel hooks and the problem of code licensed under Sun's CDDL.
- What does a DTrace probe actually do?
- DTrace safety and how it is implemented.
- Build system changes to add CTF (Compact C Type Format) data to objects, shared libraries and executables.
- The DTrace test suite.
- A brief list of things to do to port the DTrace facility to other BSD-derived operating systems.

A closer look at the ZFS file system
simple administration, transactional semantics, end-to-end data integrity
SUN's ZFS file system became part of FreeBSD on 6th
April 2007. ZFS is a new kind of file system that
provides simple administration, transactional
semantics, end-to-end data integrity, and immense
scalability. ZFS is not an incremental improvement
to existing technology; it is a fundamentally new
approach to data management. We've blown away 20
years of obsolete assumptions, eliminated complexity
at the source, and created a storage system that's
actually a pleasure to use.
ZFS presents a pooled storage model that completely
eliminates the concept of volumes and the associated
problems of partitions, provisioning, wasted bandwidth
and stranded storage. Thousands of file systems can
draw from a common storage pool, each one consuming
only as much space as it actually needs. The combined
I/O bandwidth of all devices in the pool is available
to all filesystems at all times.
All operations are copy-on-write transactions, so
the on-disk state is always valid. There is no need
to fsck(1M) a ZFS file system, ever. Every block
is checksummed to prevent silent data corruption,
and the data is self-healing in replicated (mirrored
or RAID) configurations. If one copy is damaged,
ZFS detects it and uses another copy to repair it.

Interfacing embedded FreeBSD with U-Boot
Working with the de facto standard for an initial level boot loader
In the embedded world U-Boot is a de facto standard
for an initial level boot loader (firmware). It
runs on a great number of platforms and architectures,
and is open source.
This talk covers the development work on integrating
FreeBSD with U-Boot-based systems. Starting with
an overview of differences between booting an
all-purpose desktop computer vs. embedded system,
FreeBSD booting concepts are explained along with
requirements for the underlying firmware.
Historical attempts to interface FreeBSD with this
firmware are mentioned and explanation given on why
they failed or proved incomplete. Finally, the
recently developed approach to integrate FreeBSD
and U-Boot is presented, with implementation details
and particular attention on how it's been made
architecture and platform independent, and how
loader(8) has been bound to it.

Using FreeBSD to Promote Open Source Development Methods
In this talk we present Aerosource, an initiative
to bring Open Source Software development methods
to internal software developers at The Aerospace
Corporation.
Within Aerosource, FreeBSD is used in several key
roles. First, we run most of our tools on top of
FreeBSD. Second, the ports collection (both official
ports and custom internal ones) eases our administrative
burden. Third, the FreeBSD project serves as an
example and role model for the results that can be
achieved by an Open Source Software projects. We
discuss the development infrastructure we have built
for Aerosource based largely on BSD licensed software
including FreeBSD, PostgreSQL, Apache, and Trac.
We will also discuss our custom management tools
including our system for managing our custom internal
ports. Finally, we will cover our development
successes and how we use projects like FreeBSD as
exemplars of OSS development.

BSD licensed C++ compiler
LLVM is a suite of carefully designed open source
libraries that implement compiler components (like
language front-ends, code generators, aggressive
optimizers, Just-In-Time compiler support, debug
support, link-time optimization, etc.). The goal
of the LLVM project is to build these components
in a way that allows them to be combined together
to create familiar tools (like a C compiler),
interesting new tools (like an OpenGL JIT compiler),
and many other things we haven't thought of yet.
Because LLVM is under continuous development, clients
of these components naturally benefit from improvements
in the libraries.
This talk gives an overview of LLVM's design and
approach to compiler construction, and gives several
example applications. It describes applications of
LLVM technology to llvm-gcc (a C/C++/Objective C
compiler based on the GNU GCC front-end), the OpenGL
stack in Mac OS/X Leopard, and Clang. Among other
things, the Clang+LLVM Compiler provides a fully
BSD-Licensed C and Objective-C compiler (with C++
in development) which compiles code several times
faster than GCC, produces code that is faster than
GCC in many cases, produces better warnings and
error messages, and supports many other applications
(e.g. static analysis and refactoring).

The FreeBSD, GNU/Linux, Solaris, and Windows operating
systems have kernels that provide comparable
facilities. Interestingly, their code bases share
almost no common parts, while their development
processes vary dramatically. We analyze the source
code of the four systems by collecting metrics in
the areas of file organization, code structure,
code style, the use of the C preprocessor, and data
organization. The aggregate results indicate that
across various areas and many different metrics,
four systems developed using wildly different
processes score comparably. This allows us to posit
that the structure and internal quality attributes
of a working, non-trivial software artifact will
represent first and foremost the engineering
requirements of its construction, with the influence
of process being marginal, if any.

This talk is the result of an after-meeting discussion
with a few folks, when it became apparent that there
is some confusion as to how to deal with OpenBSD
in small and large environments. The topic of
installation and upgrading came up again. This talk
is aimed to hopefully dispel many of the rumors,
provide a thorough description and walk through of
the various stages of running OpenBSD in any size
environment, and some of the features and tools at
the administrator`s disposal.
Okan Demirmen has been working with UNIX-like systems
for as long as he can remember and has found OpenBSD
to match some of the same philosophies in which he
believes, namely simplicity and correctness, and
reap the benefits of such.

Ogg version (6.5 Mb, 4 minutes 48 seconds), MP3 version (8.2 Mb, 4 minutes 48 seconds)
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.

Special NYC*BUG meeting with FreeBSD developer Brooks Davis
Since late 2000 we have developed and maintained a
general purpose technical and scientific computing
cluster running the FreeBSD operating system. In
that time we have grown from a cluster of 8 dual
Intel Pentium III systems to our current mix of 64
dual, quad-core Intel Xeon and 289 dual AMD Opteron
systems.
In this talk we reflect on the system architecture
as documented in our BSDCon 2003 paper "Building a
High-performance Computing Cluster Using FreeBSD"
and our changes since that time. After a brief
overview of the current cluster we revisit the
architectural decisions in that paper and reflect
on their long term success. We then discuss lessons
learned in the process. Finally, we conclude with
thoughts on future cluster expansion and designs.

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.

SSARES: Secure Searchable Automated Remote Email
Storage - A usable, secure email system on a remote
untrusted server
The increasing centralization of networked services
places user data at considerable risk. For example,
many users store email on remote servers rather
than on their local disk. Doing so allows users to
gain the benefit of regular backups and remote
access, but it also places a great deal of unwarranted
trust in the server. Since most email is stored in
plaintext, a compromise of the server implies the
loss of confidentiality and integrity of the email
stored therein. Although users could employ an
end-to-end encryption scheme (e.g., PGP), such
measures are not widely adopted, require action on
the sender side, only provide partial protection
(the email headers remain in the clear), and prevent
the users from performing some common operations,
such as server-side search.
To address this problem, we present Secure Searchable
Automated Remote Email Storage (SSARES), a novel
system that offers a practical approach to both
securing remotely stored email and allowing
privacy-preserving search of that email collection.
Our solution encrypts email (the headers, body, and
attachments) as it arrives on the server using
public-key encryption. SSARES uses a combination
of Identity Based Encryption and Bloom Filters to
create a searchable index. This index reveals little
information about search keywords and queries, even
against adversaries that compromise the server.
SSARES remains largely transparent to both the
sender and recipient. However, the system also
incurs significant costs, primarily in terms of
expanded storage requirements. We view our work as
a starting point toward creating privacy-friendly
hosted services.

OpenBSD 4.2 Release Song - "100001 1010101"
Source: OpenBSD
Added: 02 November 2007
Tags: openbsd, artwork
Ogg version (6.4 Mb, 4 minutes 4- seconds), MP3 version (4.0 Mb, 4 minutes 40 seconds)
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.

Cryptography has a reputation of slowing down
applications. However if done correctly, it can
actually be used to improve performance by storing
high-value/high-cost results "in public." In addition
the same techniques can solve common security
problems such as authorization, parameter scanning,
and parameter rewriting.
All are welcome - no previous experience with
cryptography is required, and the techniques will
be presented in a programming-language neutral
format.
Nick Galbreath have been working on high performance
servers and web security at various high profile
startups since 1994 (most recently Right Media).
He holds a Master degree of Mathematics from Boston
University, and published a book on cryptography.

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.

About the Speaker
Marc Spitzer started as a VAX/VMS operator who
taught himself some basic scripting in DCL to help
me remember how to do procedures that did not come
up enough to actually remember all the steps, this
was in 1990. Since then he has worked with HPUX,
Solaris, Windows, Linux, and the BSDs, FreeBSD being
his favorite. He has held a variety of positions,
admin and engineering, where he has been able to
introduce BSD into his work place. He currently
works for Columbia University as a Systems
Administrator.
He is a founding member of NYCBUG and LispNYC and
on the board of UNIGroup.
Most of his career has been building tools to solve
operational problems, with extra effort going to
the ones that irritated him personally. He takes a
great deal of pride in not needing a budget to solve
most problems.

"The Real Unix Tradition"
UNIX hackers, all standing on the shoulders of giants.
"...the number of UNIX installations has grown to
10, with more expected..." - Dennis Ritchie and Ken
Thompson, June 1972
"Well, it was all Open Source, before anybody really
called it that". - Brian Redman, 2003
UNIX is the oldest active and growing computing
culture alive today. From it`s humble roots in the
back room at Bell Laboratories, to today`s global
internet infrastructure- UNIX has consistently been
at the core of major advances in computing. Today,
the BSD legacy is the most direct continuation of
the most successful principles in UNIX, and continues
to lead major advances in computing.
Why? What`s so great about UNIX?
This lecture aims to prove that UNIX history is
surprisingly useful (and fun)- for developers,
sysadmins, and anyone working with BSD systems.
About the speaker

The FreeBSD Project is one of the oldest and most
successful open source operating system ... all
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.
Speaker: Robert Watson Robert Watson is a researcher
at the University of Cambridge Computer Laboratory
investinging operating system and network security.
Prior to joining the Computer Laboratory to work
on a PhD, he was a Senior Principal Scientist at
McAfee Research, now SPARTA ISSO, a leading security
research and development organization, where he
directed government and commercial research contracts
for customers that include DARPA, the US Navy, and
Apple Computer. His research interests include
operating system security, network stack structure
and performance, and windowing system structure.
He is also a member of the FreeBSD Core Team and

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.

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.

Integrated Enterprise Security Management
Security policies are a key component in protecting
enterprise networks. But, while there are many
diverse defensive options available, current models
and mechanisms for mechanically-enforced security
policies are limited to traditional admission-based
access control. Defensive capabilities include among
others logging, firewalls, honeypots, rollback/recovery,
and intrusion detection systems, while policy
enforcement is essentially limited to one-off access
control. Furthermore, access-control mechanisms
operate independently on each service, which can
(and often does) lead to inconsistent or incorrect
application of the intended system-wide policy. We
propose a new scheme for global security policies.
Every policy decision is made with near-global
knowledge, and re-evaluated as global knowledge
changes. Using a variety of actuators, we make the
full array of defensive capabilities available to
the global policy. Our goal is a coherent,
enterprise-wide response to any network threat.

MP3 version
The presentation will discuss Subversion from both
client and server points of view. It will show how
to create repositories and how to make them accessible
over the network using different access schemes
like http://, file:// or svn://. Pointers are given
on securing the repositories and on authenticating
and authorizing the clients. Next, the presentation
shows how an user interacts with the repository and
describes some of the important Subversion client
commands. Finally, it deals with administrating
the repository using "hook scripts".
Ivan Ivanov is generally interested in Version
Control Systems since his student years in Sofia
University, Bulgaria, where he set up and maintained
a CVS server for an academic project. When Subversion
became a fact and proved to be "a better CVS" he
researched it and last year deployed it for his
NYC-based employer Ariel Partners
(http://www.arielpartners.com/). He intergrated the
Subversion repositories with Apache Web Server over
https to enable a reliable and secure way to access
them from any point.

In NASSCOM Quality Summit 2006: Setting benchmarks in global outsourcing, Bangalore, India, September 2006. National Association of Software and Services Companies (NASSCOM)., International Workshop on Global Software Development for the Practitioner, pages 73-79. ACM Press, May 2006, Linux Format, (11):60?63, September/October 2006. In Greek.
FreeBSD is a sophisticated operating system developed
and maintained as open-source software by a team
of more than 350 individuals located throughout the
world. This study uses developer location data, the
configuration management repository, and records
from the issue database to examine the extent of
global development and its effect on productivity,
quality, and developer cooperation. The key findings
are that global development allows round-the-clock
work, but there are some marked differences between
the type of work performed at different regions.
The effects of multiple dispersed developers on the
quality of code and productivity are negligible.
Mentoring appears to be sometimes associated with
developers living closer together, but ad-hoc
cooperation seems to work fine across continents.

Introduction to Multithreading and Multiprocessing in the FreeBSD SMPng Network Stack (370 Kb)
EuroBSDCon 2005 took place in Basel, Switzerland
in November, 2005. Due to an injury, I was unable
to attend the conference itself, and my talks were
presented in absentia by Poul-Henning Kamp and Ed
Maste, who have my greatest appreciation!
The FreeBSD SMPng Project has spent the past five
years redesigning and reimplementing SMP support
for the FreeBSD operating system, moving from a
Giant-locked kernel to a fine-grained locking
implementation with greater kernel threading and
parallelism. This paper introduces the FreeBSD SMPng
Project, its architectural goals and implementation
approach. It then explores the impact of SMPng on
the FreeBSD network stack, including strategies for
integrating SMP support into the network stack,
locking approaches, optimizations, and challenges.

How the FreeBSD Project Works (EuroBSDCon 2006 Full Conference) (4.4 Mb), TrustedBSD presentation on Audit and priv(9) (Developer Summit) (166 Kb)
EuroBSDCon 2006 took place in Milan, Italy, and not
only offered excellent food on a flexible schedule,
but also an interesting array of talks on work
spanning the BSD's. On this page, you can find my
slides from the FreeBSD developer summit and full
conference.
Status report on the TrustedBSD Project: introduction
and status regarding Audit, plus a TODO list;
introduction to the priv(9) work recently merged
to 7.x.
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.

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.

This song details the process that Ty has to go
through to make the art and music for each OpenBSD
release. Ty and Theo really do go to a (very specific)
bar and discuss what is going on in the project,
and then try to find a theme that will work...

UNIX professionals are busy these days. Setting up
routers and firewalls are fundamental to any network,
but in environments where the focus is on various
applications, (servers, workstations, and the
software that runs on them), it`s difficult for a
business not to choose off-the-shelf SOHO routers
and networking gear. The web management gui`s are
understandable by everyone, (even techs without
UNIX knowledge), and the gear is cheap - this saves
time and money.
In the meantime, the features of your average Linksys
or Netgear router often leave MUCH to be desired,
(https auth management, for one simple example).
Enter m0n0wall and PFSense, 2 BSD based packaged
router/firewall solutions that are as solid and
full featured as you`d expect from any BSD system-
PLUS THEY HAVE HTML WEB INTERFACES FOR MANAGEMENT!
m0n0wall and PFSense become an easy sell in any
small professional enviornment, any competent tech
can manage the network within minutes... At home,
in every hackers home network, they free the hacker
to have trusted tools available, but are as time-saving
as using any Linksys router.
m0n0wall and PFSense are both light and clean,
designed to run on embedded systems- (Soekris,
WRAP), but are monsters when unleashed on even
legacy PC`s around the office. If you manage UNIX
networks and systems all day, do you really want
to manage the router for your DSL when you get home?
But then doesn`t it bug you to use a chincey Linksys
box?
Ike has been a member of NYC*BUG since we first
launched in January 2004. He is a long-time member
of the Lower East Side Mac Unix User Group. He has
spoken frequently on a number of topics at various
venues, particularly on the issue of FreeBSD`s jail
(8).

COMPLETE Hard Disk Encryption with FreeBSD, by Marc Schiesser
Learn how to effectively protect not only your data
but also your applications.
Most technologies and techniques intended for
securing digital data focus on protection while the
machine is turned on mostly by defending against
remote attacks. An attacker with physical access
to the machine, however, can easily circumvent these
defenses by reading out the contents of the storage
medium on a different, fully accessible system or
even compromise program code on it in order to leak
encrypted information. Especially for mobile users,
that threat is real. And for those carrying around
sensitive data, the risk is most likely high. This
talk will introduce a method of mitigating that
particular risk by protecting not only the data
through encryption, but also the applications and
the operating system from being compromised while
the machine is turned off.

Our Topic:
Network Protocol Development Tools and Techniques for FreeBSD
Our Speaker:
George Neville-Neil, co-author of the "Design and
Implementation of the FreeBSD Operating System"
"daemon" book.
Our Topic:
While computers have gotten faster and more powerful
the tools we use to develop network protocols, such
as TCP, UDP, IPv4 and IPv6 have not. Most network
protocols are developed, in C, in the kernel, and
require a lot of work to test. Over the past year
or so I have been working with virtual machines, a
couple of pieces of open source software, and begun
developing a library for use in protocol testing.
This talk will cover three topics:
- Developing and testing kernel code with Virtual Machines
- Finding good tests for networking code
- Packet Construction Set (PCS) a new library for
writing protocol tests

We talk with Daniel Seuffert about BSD. Several
flavours of bsd were represented in a joint BSD
booth: openbsd, freebsd, netbsd and miros. Daniel
is representative of the FreeBSD project and among
other things talks about the different operating
systems that are build on top of freebsd. For
instance, there are two distributions called pcbsd
and desktopbsd that are targetted towards desktop
users. There also is a version that specializes on
security entitled trustedbsd.
