Central Syslog
Source: bsdtalk

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

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

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

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

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

Universidad Nacional de Colombia I was born in
Bogota, Colombia but I am an Italian citizen. My
experience with computers started when I was about
12 years old With the TRS-80 Color Computer first
using Basic and the OS-9. I studied electronics for
3 years but became tired of worrying about "whatever
happened to electrons in there" and moved to
Mechanical Engineering. For a while I rested from
the computer world until the Internet came stepping
along. I started using FreeBSD around 1995 and soon
fell in love with the idea of being able to install
a complete version of UNIX from the net with just
one floppy. After submitting a the 999th port to
the FreeBSD project Walnut Creek was kind enough
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
healthful environment.

In this talk, we will discuss the past and present
history and the design principles of the OpenBSD
hardware sensors framework. Sensors framework
provides a unified interface for storing, registering
and accessing information about hardware monitoring
sensors. Sensor types include, but are not limited
to, temperature, voltage, fan RPM, time offset and
logical drive status. The framework spans
sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8),
ntpd(8), snmpd(8) and more than 67 drivers, ranging
from I2C temperature sensors and Super I/O hardware
monitors to IPMI, RAID and SCSI enclosures. Several
third-party tools are also available, for example,
a plug-in for Nagios and ports/sysutils/symon.
Originally based on some ideas from NetBSD, the
framework has sustained many improvements in OpenBSD,
and was ported and committed to FreeBSD and DragonFly
BSD.
Constantine A. Murenin is an MMath graduate student
at the David R. Cheriton School of Computer Science
at the University of Waterloo (CA). Prior to his
graduate appointment, Constantine attended and
subsequently graduated from East Carolina University
(US) and De Montfort University (UK), receiving two

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

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

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.

Edd Barrett will speak about using the BSD Platform
as a means of typesetting from a practical standpoint
at EuroBSDcon 2008. Edd Barrett does not wish to
go into the technicalities of each typesetter, but
rather state which are good for certain types of
document, and which tools (ports and packages),
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.

Many BSD-licensed strategies of various levels of
maturity exist to implement multiplicity, herein
defined as the introduction of plurality to
traditionally singular computing environments via
isolation, virtualization, or other method. For
example, the chroot utility introduces an additional
isolated root execution environment within that of
the host; or an emulator provides highly-isolated
virtual systems that can run complete native or
foreign operating systems. Motivations for multiplicity
vary, but a demonstrable desire exists for users
to obtain root or run a foreign binary or operating
system. We propose a hands-on survey of portable
and integrated BSD-licensed multiplicity strategies
applicable to the FreeBSD, OpenBSD, DragonFlyBSD
and NetBSD operating systems on the i386 architecture.
We will also address three oft-coupled disciplines:
software storage devices, the installation of
operating system and userlands in multiplicity
environments plus the management of select multiplicity
environments. Finally we will comment on each
strategies potential limits of isolation, compatibility,
independence and potential overhead in comparison
to traditional systems. Keywords: multiplicity,
virtualization, chroot, jail, hypervisor, xen,
compat.
Michael Dexter has used Unix systems since 1991 and
BSD-licensed multiplicity strategies for over five
years. He is the Program Manager at the BSD Fund
and Project Manager of the BSD.lv Project.
EuroBSDCon 2008 - Nick Barkas - Dynamic memory allocation for dirhash in UFS2

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.
Keywords: dirhash, ufs2, filesystems, performance tuning

Traditional project management methodologies are
typically based on the waterfall model where there
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
fundamentally changed by the time the project is
delivered.

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.

Institut fr Nachrichtentechnik (telecommunication)
