SCALE 8x - 2010 Southern California Linux Expo - Everyone http://www.socallinuxexpo.org/scale8x/taxonomy/term/1/0 en Communication Privacy for a Free Society http://www.socallinuxexpo.org/scale8x/presentations/communication-privacy-free-society <p>Secure free as in freedom and free as in cost real-time communications for everyone</p> <div class="field field-type-text field-field-presentation-short-abs"> <div class="field-items"> <div class="field-item odd"> The GNU Telephony Secure Calling initiative was originally formed to make passive voice communication intercept a thing of the past. While it is true that technological means for mass communication intercept has grown with incremental improvements in communication technology, the means to apply and use encryption techniques to counter these abuses and offer communication privacy on a large scale using free software have also become possible. In particular, I will be talking about how the GNU ZRTP stack (and our related ZRTP4J used in SIP communicator), ZRTP enabled clients such as Twinkle, and GNU SIP Witch can be used to create and deploy network scalable secure VoIP solutions for individuals, private organizations, and even national governments. </div> </div> </div> <div class="field field-type-text field-field-presentation-long-abs"> <div class="field-items"> <div class="field-item odd"> <p>Last September we presented the technological aspect of the secure calling project at LinuxCon 2009. This was an important milestone in presenting the technological aspect of how this project will offer the means for anyone to create and deploy network scalable and secure VoIP/collaboration solution to enable privacy without the need for a central service provider or proprietary software to achieve these goals. Our overall vision is to facilitate both solutions that are privately built, such as for organizations that wish to have secure communication as a foundation, and especially which can be autonomously assembled over the public Internet as a full public alternative to Skype using only free software and that depends purely on existing DNS for user lookup, rather than a service provider, and eliminates the use of source secret clients which can of course be compromised.</p> <p>Background of architecture:</p> <p>A SIP user agent is a front-end application which supports a standard set of protocols to enable registering with a directory service (SIP registrar) and a routing server to establish calls by sip uri's. Some user agents can also directly connect if you know each parties IP address, though some will not allow that because in the SIP standard a UA is supposed to only accept calls received by it's published "contact" uri that was sent to a registrar, and not just any arbitrary client calling it directly without looking that up first (such as by ip address).</p> <p>Some use this behavior as a security means, by having the UA generate a UUID or some other kind of token for the contact uri to publish with a registrar, so that unless the call resolved through the registrar it is using there would be no way to directly know what uri the agent will respond to. Most UA's use<br /> it as a means to separate which "identity" it is receiving a call as, since a UA can register itself with multiple registrars which may represent different service providers, and each one would have a different and unique contact uri.</p> <p>Many VoIP providers offer themselves as a "backend" service for SIP. This means your UA is tethered to said provider, and your call peering goes through them. That looks like a standard telephone service simply conducted on TCP/IP rather than something new. It also is very convenient from a regulatory and intercept regime since all call control and routing happens at their end.</p> <p>One can run a local asterisk server as a backend SIP registrar and routing service, but it (and bayonne) makes several assumptions. First, the call must connect to the server before the destination is even determined. This means all audio is established through the server first, and then hopped across the server to the final destination, converted as necessary. In one sense it is convenient, but since the audio session is established with and must be decoded by the server first, it obviously cannot pass encrypted audio end-to-end. It also means that said server has to have all supported codecs that will be used, including proprietary or patent encumbered ones if calls are supported with them. It means the call capacity is compute-bound, and induces latency. Finally, in the case of Asterisk, it was never designed for arbitrary uri routing, but rather for resolving things that are purely telephone numbers in form.</p> <p>Skype actually is a kind of user agent that includes/integrates code for specific routing and network connection logic, but also depends on the Skype backend to find users. It is of course also proprietary, and the protocols it uses are undocumented and proprietary as well.</p> <p>SIP Witch operates by keeping the network routing layer separate from the user agent rather than merging them like the Skype application does, hence any standard's compliant SIP client can be used with it. It also peers calls by URI using DNS lookup. It also does destination routing, so the final destination is determined first, and the calling user agent is then directed to connect itself with the final destination's IP address directly, rather than the asterisk/bayonne model where user agent is directed to connect with the server and without the need of a central directory service. This means all media connections are established peer-to-peer, and this can support an end-to-end encrypted media channel like ZRTP. It also means all codecs are negotiated between the endpoints, which also means<br /> conducting calls does not require having patent licensed codecs, though the ua's may have and certainly use them if they choose. That is the user's decision and circumstances of course, but at least is not something that is burdened or otherwise forced on the software used for conveyance as well.</p> </div> </div> </div> <div class="field field-type-text field-field-presentation-speaker-id"> <div class="field-items"> <div class="field-item odd"> Speaker: <a href="/scale8x/speakers/david-sugar">David Sugar</a> </div> </div> </div> <fieldset class="fieldgroup group-presentation-downloads"><legend>Downloads</legend><div class="field field-type-text field-field-presentation-url"> <div class="field-items"> <div class="field-item odd"> <a href="https://www.socallinuxexpo.org/scalemedia/scale/simple_cfp/20100227-182252/David_Sugar.odp">Presentation</a></div> </div> </div> <div class="field field-type-text field-field-presentation-audio"> <div class="field-items"> <div class="field-item odd"> <a href="http://audio.socallinuxexpo.org/Saturday/Track%20A/talk%20%235%20(David%20Sugar).mp3">Audio</a></div> </div> </div> </fieldset> http://www.socallinuxexpo.org/scale8x/presentations/communication-privacy-free-society#comments Everyone Program Track A Fri, 18 Jun 2010 00:00:53 +0000 2286 at http://www.socallinuxexpo.org/scale8x Ready or Not, IPv6 is Here: Preparing Your Linux Networks for IPv6 http://www.socallinuxexpo.org/scale8x/presentations/ready-or-not-ipv6-here-preparing-your-linux-networks-ipv6 <p>In this educational session, John Curran, President and CEO of ARIN will discuss how Linux IT professionals can prepare for IPv6, the benefits of adopting now, and the available resources to help communicate the value of IPv6 to their organizations.</p> <div class="field field-type-text field-field-presentation-short-abs"> <div class="field-items"> <div class="field-item odd"> With less than 10% of IPv4 address space remaining, it is extremely urgent that all organizations adopt IPv6 – the next generation of IP technology – before time runs out and the global Internet community is fragmented.

It is designed to work alongside your operating system's packaging tool. I'll talk about the advantages of separating the packaging of your applications from your base OS. Separating the packaging of applications from the base OS system ensures that application packages and their dependencies don't interfere with the functioning of the base OS. For example, your OS comes with Perl 5.6.1, but your application needs 5.8.9. Upgrading the OS copy of Perl may break other applications. By using tpkg and installing your application and the newer version of Perl in a location reserved for tpkg you avoid any conflicts. Tpkg is cross platform, so although you may have two or three different operating systems in your environment you can use a common tool to package and deploy your applications on those systems.</p> <p>I'll talk about some of the unique features of tpkg that make it ideally suited to packaging applications, and distinguish tpkg from OS packaging tools like rpm and dpkg. Tpkg supports encrypting some or all of the files in the package, so your application package can contain secret files like SSL or SSH keys, database passwords, etc. Also supported are external hooks that can be used to tie into a system configuration management tool, allowing packages to request accounts and other OS configuration.</p> <p>The process of making and deploying packages in tpkg will be covered.</p> <p>The process of building a package is quite simple. The package metadata is stored in an XML or YAML configuration file. Packages can have pre and post install and removal scripts. Incorporating init scripts and crontabs into packages will be discussed. cpan2tpkg and gem2tpkg utilities are also available to readily package Perl modules or Ruby gems.</p> <p>Tpkg supports dependencies both on other tpkg packages as well as native packages, and tpkg handles dependency resolution and automatic dependency installation of both tpkg and native dependencies. As such installing applications with complex dependency trees is simple and fast. The deployment features of tpkg allow you to automate the installation, upgrade or removal of packages across a large number of systems.

As the collection of Activities grew, more programs of interest to older students, and even adults, were added.</p> <p>Participants will learn about the latest and greatest Sugar Activities and the simple processes for getting them.
