• DNSSEC and DANE
    Viktor Dukhovni -on- DNSSEC and DANE Note: WE ARE MEETING AT TWO SIGMA!! We'll need names, and you will need IDs. RSVP will open Wednesday October 3rd, 2018, 4:30pm. The talk will introduce the audience to DNSSEC and its role in securing server-to-server email transport via opportunistic use of DANE TLSA records to resist active attacks on STARTTLS. We will cover DNSSEC and DANE theory and practice, focusing on how to avoid operational pitfalls. Adoption metrics from an ongoing DNSSEC/DANE survey will be briefly covered. Questions from the audience welcome. Coincidentally, ICANN will be replacing the original 2010 root zone key-signing-key (KSK-2010, key id 19036) with the new KSK-2017 (key id 20326) the day after the talk. The audience should be well prepared for the change. Afterwards: Join us afterwards at the Cupping Room Cafe where we'll continue the discussion over drinks and/or food. The Cupping Room Cafe is located at 359 W Broadway, two blocks from the venue. Speaker bio: Viktor Dukhovni is the maintainer of the TLS stack in Postfix and the DANE and X.509 support in OpenSSL. He is the author of RFC7435, which broadly defines opportunistic security and RFCs 7671 and 7672 which update DANE and apply it to SMTP. He developed and operates a DNSSEC/DANE survey which helps to drive adoption and detect/fix implementation obstacles.

  • Linux User Namespaces
    Michael Kerrisk -on- Linux User Namespaces Note: WE ARE MEETING AT TWO SIGMA!! We'll need names, and you will need IDs. RSVP will open Wednesday September 5th, 2018, 4:30pm. The Linux kernel's user namespaces feature http://man7.org/linux/man-pages/man7/user_namespaces.7.html is one of the cornerstones in building many interesting technologies that allow isolation and sandboxing of applications, for example running containers without root privileges and sandboxes for web browser plug-ins. In this presentation, we'll look in detail at user namespaces, building up a basic understanding of what a user namespace is and going on to questions such as: what does being "superuser inside a user namespace" allow you do (and what does it not allow); what is the relationship between user namespaces and other namespace types (PID, UTS, network, etc.); and what are the security implications of user namespaces? We'll also explore some simple shell commands that can be used for creating and experimenting with user namespaces in order to better understand how they work. We'll conclude with a brief survey of some use cases for user namespaces. Afterwards: Join us afterwards at the Cupping Room Cafe where we'll continue the discussion over drinks and/or food. The Cupping Room Cafe is located at 359 W Broadway, two blocks from the venue. Speaker bio: Michael Kerrisk is a programmer, writer, and trainer who has a passion for investigating and explaining software systems. He is the author of The Linux Programming Interface http://man7.org/tlpi/ , a widely acclaimed book on Linux (and UNIX) system programming. He has been actively involved in the Linux development community since 2000, operating mainly in the area of testing, design review, and documentation of kernel-user-space interfaces. Since 2004, he has maintained the Linux man-pages project https://www.kernel.org/doc/man-pages/ , which provides the primary documentation for Linux system calls and C library functions. Michael is a New Zealander, living in Munich, Germany, from where he operates a training business ( http://man7.org/training/ ) providing low-level Linux programming courses primarily in Europe, and occasionally in North America and further afield.

    You're invited to hack along with the New York Linux Users Group! We are very kindly hosted by the New York Amatuer Computer Club (http://nyacc.org/) which meets at NYU. Please have a government issued form of ID with you. This is a peer-supported workshop where we get together to share current challenges and approaches to solving problems or to just work alongside like-minded individuals and learn through osmosis. This event is NOT a lecture-style meeting. The agenda is generally set when someone poses a question, so bring questions! Some topics up for discussion are: • Install and configuration assistance • Documentation, standards, and best practices • Current events/Conventions • Release testing and bug reporting • Getting started with languages like Python and LaTeX • -Other projects (Pi/Arduino/Analog devices) We will also have brief (approx. 5-10 minute) lightning talks, so please speak with a coordinator if you're interested in sharing some of your work. A laptop is not required but strongly recommended. Bring a project, topic, and questions and work with other enthusiasts on using Linux or get assistance with your own Linux/Open Source projects. Geeks are more sociable solving problems rather then just talking about themselves.

  • Crostini: Running Linux applications on Chrome OS
    David Reveman and Zach Reizner -on- Crostini Running Linux applications on Chrome OS Note: WE ARE MEETING AT TWO SIGMA!! We'll need names, and you will need IDs. RSVP will open Wednesday July 4th, 2018, 4:30pm. Crouton has long been an option for running Linux applications on Chromebooks. However, it lacked UX integration and required the device to be in “dev”-mode, which meant that many of the security benefits of Chrome OS were lost. Crostini brings Linux applications to Chrome OS with proper UX integration and all security benefits intact. This presentation will provide an overview of Crostini, and a detailed description of the Chrome OS graphics stack in order to explain how the Crostini UX integration has been accomplished. It will also provide useful tips for how to help make applications work better on Chrome OS, and how to make the most of a Chromebook as a Linux development device. Afterwards: Join us afterwards at the Cupping Room Cafe where we'll continue the discussion over drinks and/or food. The Cupping Room Cafe is located at 359 W Broadway, two blocks from the venue. Speaker Bio: David Reveman worked on bringing compositing to the Linux desktop 10 years ago when employed by Novell. In the last 7 years, David has worked at Google, building the Chrome compositor, bringing Android apps to Chrome OS with native graphics performance, and most recently, bringing Linux applications to Chromebooks. Zach Reizner has been working on Chrome OS platforms for 4 years, with a focus on graphics. Recently, Zach has been working on crosvm, the new virtual machine monitor powering crostini, and virtio-wayland, the transport protocol underlying the windowing integration. Currently, Zach is working on bringing GPU acceleration to applications running under Crostini, and advancing Rust usage throughout Chrome OS.

  • A Greybeard's Worst Nightmare
    Daniel Riek -on- A Greybeard's Worst Nightmare How Containers and Kubernetes re-defined the GNU/Linux Operating System. Note: WE ARE MEETING AT TWO SIGMA!! We'll need names, and you will need IDs. RSVP will open Wednesday June 6th, 2018, 4:30pm. Containers and Kubernetes with the concepts of application-centric packaging, process isolation through Linux containers, and immutable infrastructure are shaking up the core traditions of today's GNU/Linux operating systems. We are challenging assumptions and approaches derived from the past 40+ years of UNIX tradition. The Linux distribution as we know it, is morphing into new concept of containerized, multi-instance, multi-user applications, which can be deployed in scale-out environments. In this session, we'll assess this new OS environment and take a look at the consequences this new OS model has. Afterwards: Join us afterwards at the Cupping Room Cafe where we'll continue the discussion over drinks and/or food. The Cupping Room Cafe is located at 359 W Broadway, two blocks from the venue. Speaker Bio: Daniel leads the Artificial Intelligence Center of Excellence in the Office of the CTO at Red Hat, which is tasked with advancing the adoption of AI across Red Hat's products, services and communities. Before that, Daniel most recently managed a cross-product group and was deeply involved in Red Hat's broader Container and Platform strategy. Daniel has been in the Open Source business since co-founding ID-Pro, one of the early Linux-startups in Europe in 1996. He lead Product Management for Red Hat Enterprise Linux from 2005 to 2011.
