    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.

    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.

    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.

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.

    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.
    In 2007 Martin Schuette already gave a talk on Syslog at the Chemnitze Linux-Tage (http://chemnitzer.linux-tage.de/2007/vortraege/detail.html?idx=547 in german; for a newer english version see these slides for a seminar talk: http://fara.cs.uni-potsdam.de/~mschuett/uni/syslog-protocols-080522.pdf).

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

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

    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.

    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.
    Hauke Fath works as a systems administrator for the Institut fr Nachrichtentechnik (telecommunication) at Technische Universitt Darmstadt. He has been using NetBSD since 1994, when he first booted a NetBSD 1.0A kernel on a Macintosh SE/30. NetBSD helped shaping his career by causing a slow drift from application programmer's work towards systems and network administration. Hauke Fath holds a MS in Physics and became a NetBSD developer in late 2006.

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

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

    The University of Toronto is a large educational institutional with over 70,000 students and 10,000 staff and faculty. For the past three years, we have developed and implemented a ubiquitous VPN service, based up on OpenVPN and FreeBSD. The service has over 3000 active customers, with up to 35 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 Source and freely available.

    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.

    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.

    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.

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.

    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.

    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.

    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.

    "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.

    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.

    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 GUIs 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 environment, 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 PCs around the office.

    Nearly 10 years ago Kirk McKusick wrote a history of the Berkeley Unix distributions for the O'Reilly book "Open Sources: Voices from the Open Source Revolution". We recommend you read his story, entitled "Twenty Years of Berkeley Unix From AT&T-Owned to Freely Redistributable" first, to see how Kirk remembers how we got here. Sadly, since it showed up in book form originally, this text has probably not been read by enough people.

    The USL(AT&T) vs BSDI/UCB court case settlement documents were not public until recently; their disclosure has made the facts more clear. But the story of how three people decided to free the BSD codebase of corporate pollution -- and release it freely -- is more interesting than the lawsuit which followed. Sure, a stupid lawsuit happened which hindered the acceptance of the BSD code during a critical period. But how did a bunch of guys go through the effort of replacing so much AT&T code in the first place? After all, companies had lots of really evil lawyers back then too -- were they not afraid?

    After a decade of development, most of the AT&T code had already been replaced by university researchers and their associates. So Keith Bostic, Mike Karels and Kirk McKusick (the main UCB CSRG group) started going through the 4.3BSD codebase to cleanse the rest. Keith, in particular, built a ragtag team (in those days, USENIX conferences were a gold mine for such team building) and led these rebels to rewrite and replace all the Imperial AT&T code, piece by piece, starting with the libraries and userland programs. Anyone who helped only got credit as a Contributor -- people like Chris Torek and a cast of .. hundreds more.

    Then Mike and Kirk purified the kernel. After a bit more careful checking, this led to the release of a clean tree called Net/2 which was given to the world in June 1991 -- the largest dump of free source code the world had ever received (for those days -- not modern monsters like OpenOffice).

    Some of these ragtags formed a company (BSDi) to sell a production system based on this free code base, and a year later Unix System Laboratories (basically AT&T) sued BSDi and UCB. Eventually AT&T lost and after a few trifling fixes (described in the lawsuit documents) the codebase was free. A few newer developments (and more free code) were added, and released in June 1994 as 4.4BSD-Lite. Just over 14 years later OpenBSD is releasing its own 4.4 release (and for a lot less than $1000 per copy).

    The OpenBSD 4.4 release is dedicated to Keith Bostic, Mike Karels, Kirk McKusick, and all of those who contributed to making Net/2 and 4.4BSD-Lite free.

    We are just plain tired of being lectured to by a man who is a lot like Naomi Campbell.

    In 1998 when a United Airlines plane was waiting in the queue at Washington Dulles International Airport for take-off to New Orleans (where a Usenix conference was taking place), one man stood up from his seat, demanded that they stop waiting in the queue and be permitted to deplane. Even after orders from the crew and a pilot from the cockpit he refused to sit down. The plane exited the queue and returned to the airport gangway. Security personnel ran onto the plane and removed this man, Richard Stallman, from the plane. After Richard was removed from the plane, everyone else stayed onboard and continued their journey to New Orleans. A few OpenBSD developers were on that same plane, seated very closeby, so we have an accurate story of the events.

    This is the man who presumes that he should preach to us about morality, freedom, and what is best for us. He believes it is his God-given role to tell us what is best for us, when he has shown that he takes actions which are not best for everyone. He prefers actions which he thinks are best for him -- and him alone -- and then lies to the public. Richard Stallman is no Spock.

    We release our software in ways that are maximally free. We remove all restrictions on use and distribution, but leave a requirement to be known as the authors. We follow a pattern of free source code distribution that started in the mid-1980's in Berkeley, from before Richard Stallman had any powerful influence which he could use so falsely.

    We have a development sub-tree called "ports". Our "ports" tree builds software that is 'found on the net' into packages that OpenBSD users can use more easily. A scaffold of Makefiles and scripts automatically fetch these pieces of software, apply patches as required by OpenBSD, and then build them into nice neat little tarballs. This is provided as a convenience for users. The ports tree is maintained by OpenBSD entirely separately from our main source tree. Some of the software which is fetched and compiled is not as free as we would like, but what can we do. All the other operating system projects make exactly the same decision, and provide these same conveniences to their users.

    Richard felt that this "ports tree" of ours made OpenBSD non-free. He came to our mailing lists and lectured to us specifically, yet he said nothing to the many other vendors who do the same; many of them donate to the FSF and perhaps that has something to do with it. Meanwhile, Richard has personally made sure that all the official GNU software -- including Emacs -- compiles and runs on Windows.

    That man is a false leader. He is a hypocrite. There may be some people who listen to him. But we don't listen to people who do not follow their own stupid rules.

    Those of us who work on OpenBSD are often asked why we do what we do. This song's lyrics express the core motivations and goals which have remained unchanged over the years - secure, free, reliable software, that can be shared with anyone. Many other projects purport to share these same goals, and love to wrap themselves in a banner of "Open Source" and "Free Software". Given how many projects there are one would think it might be easy to stick to those goals, but it doesn't seem to work out that way. A variety of desires drag many projects away from the ideals very quickly.

    Much of any operating system's usability depends on device support, and there are some very tempting alternative ways to support devices available to those who will surrender their moral code. A project could compromise by entering into NDA agreements with vendors, or including binary objects in the operating system for which no source code exists, or tying their users down with contract terms hidden inside copyright notices. All of these choices surrender some subset of the ideals, and we simply will not do this. Sure, we care about getting devices working, but not at the expense of our original goals.

    Of course since "free to share with anyone" is part of our goals, we've been at the forefront of many licensing and NDA issues, resulting in a good number of successes. This success had led to much recognition for the advancement of Free Software causes, but has also led to other issues.

    We fully admit that some BSD licensed software has been taken and used by many commercial entities, but contributions come back more often than people seem to know, and when they do, they're always still properly attributed to the original authors, and given back in the same spirit that they were given in the first place.

    That's the best we can expect from companies. After all, we make our stuff so free so that everyone can benefit -- it remains a core goal; we really have not strayed at all in 10 years. But we can expect more from projects who talk about sharing -- such as the various Linux projects.

    Now rather than seeing us as friends who can cooperatively improve all codebases, we are seen as foes who oppose the GPL. The participants of "the race" are being manipulated by the FSF and their legal arm, the SFLC, for the FSF's aims, rather than the goal of getting good source into Linux (and all other code bases). We don't want this to come off as some conspiracy theory, but we simply urge those developers caution -- they should ensure that the path they are being shown by those who have positioned themselves as leaders is still true. Run for yourself, not for their agenda.

    The Race is there to be run, for ourselves, not for others. We do what we do to run our own race, and finish it the best we can. We don't rush off at every distraction, or worry how this will affect our image. We are here to have fun doing right.

    As developers of a free operating system, one of our prime responsibilities is device support. No matter how nice an operating system is, it remains useless and unusable without solid support for a wide percentage of the hardware that is available on the market. It is therefore rather unsurprising that more than half of our efforts focus on various aspects relating to device support.

    Most parts of the operating system (from low kernel, through to libraries, all the way up to X, and then even to applications) use fairly obvious interface layers, where the "communication protocols" or "argument passing" mechanisms (ie. APIs) can be understood by any developer who takes the time to read the free code. Device drivers pose an additional and significant challenge though: because many vendors refuse to document the exact behavior of their devices. The devices are black boxes. And often they are surprisingly weird, or even buggy.

    When vendor documentation does not exist, the development process can become extremely hairy. Groups of developers have found themselves focused for months at a time, figuring out the most simple steps, simply because the hardware is a complete mystery. Access to documentation can ease these difficulties rapidly. However, getting access to the chip documentation from vendors is ... almost always a negotiation. If we had open access to documentation, anyone would be able to see how simple all these devices actually are, and device driver development would flourish (and not just in OpenBSD, either).

    When we proceed into negotiations with vendors, asking for documentation, our position is often weak. One would assume that the modern market is fair, and that selling chips would be the primary focus of these vendors. But unfortunately a number of behemoth software vendors have spent the last 10 or 20 years building political hurdles against the smaller players.

    A particularly nasty player in this regard has been the Linux vendors and some Linux developers, who have played along with an American corporate model of requiring NDAs for chip documentation. This has effectively put Linux into the club with Microsoft, but has left all the other operating system communities -- and their developers -- with much less available clout for requesting documentation. In a more fair world, the Linux vendors would work with us, and the device driver support in all free operating systems would be fantastic by now.

    We only ask that users help us in changing the political landscape.

    The last 10 years, every 6 month period has (without fail) resulted in an official OpenBSD release making it to the FTP servers. But CDs are also manufactured, which the project sells to continue our development goals.

    While tests of the release binaries are done by developers around the world, Theo and some developers from Calgary or Edmonton (such as Peter Valchev or Bob Beck) test that the discs are full of (only) correct code. Ty Semaka works for approximately two months to design and draw artwork that will fit the designated theme, and coordinates with his music buddies to write and record a song that also matches the theme.

    Then the discs and all the artwork gets delivered to the plant, so that they can be pressed in time for an official release date.

    This release, instead of bemoaning vendors or organizations that try to make our task of writing free software more difficult, we instead celebrate the 10 years that we have been given (so far) to write free software, express our themes in art, and the 5 years that we have made music with a group of talented musicians.

    OpenBSD developers have been torturing each other for years now with Humppa-style music, so this release our users get a taste of this too. Sometimes at hackathons you will hear the same songs being played on multiple laptops, out of sync. It is under such duress that much of our code gets written.

    We feel like Pufferix and Bobilix delivering The Three Discs of Freedom to those who want them whenever the need arises, then returning to celebrate the (unlocked) source tree with all the other developers.

    Last month I attended a meeting of the Ottawa Amateur Radio Club (OARC) as a member of my local BUG was giving a presentation on Ham Radio on FreeBSD. Diane Bruce, call sign VA3DB, has had her operator license since 1969 and is well known in the BSD community and for the development of ircd-hybrid. In the past year she has assisted in the creation of the Hamradio category in the FreeBSD ports tree and has become the maintainer of over 20 of the hamradio ports. She also contributed to the FreeBSD entry at Hampedia, the Wikipedia for ham operators.

    Her presentation slides are a great introduction to the various ham utilities which are available, including both descriptions and screenshots of the utilities in action.
