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.

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.
All are welcome - no previous experience with cryptography is required, and the techniques will be presented in a programming-language neutral format.

"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.

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.

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?

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.

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.

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 president of the FreeBSD Foundation.

VG sponsored the creation of a web-accellerator called "Varnish" because Squid was too slow for them. Varnish is being developed by Poul-Henning Kamp and the Norwegian Linux consultancy Linpro. This is the releaseparty for version 1.0.
The first half of the talk will introduce Varnish and present some of the novel features it brings to the business of web-serving.
The second half of the talk, using Varnish as the example, will show ways to get the most performance out of modern hardware and operating systems.

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.

iSCSI
not an Apple appliance.iSCSI is not an Apple appliance.
The i in iSCSI stands for internet, some say for insecure, personally I like to think interesting. I'll try to share the road followed from RFC-3720 to the actual working driver, the challenges, the frustrations.
