  • Authentication and authorization in Samba 4

    Volker Lendecke is one of the first contributors to Samba, having submitted his first patches in 1994. In addition to developing other important file-sharing tools, he's heavily involved in development of the winbind service, which is implemented in winbindd. Although the core Active Directory (AD) domain controller (DC) code was written by his colleague Stefan Metzmacher, winbind is a crucial component of Samba's AD functionality. In his information-packed talk at FOSDEM 2018, Lendecke said he aimed to give a high-level overview of what AD and Samba authentication is, and in particular the communication pathways and trust relationships between the parts of Samba that authenticate a Samba user in an AD environment.

  • Two FOSDEM talks on Samba 4

    Much as some of us would love never to have to deal with Windows, it exists. It wants to authenticate its users and share resources like files and printers over the network. Although many enterprises use Microsoft tools to do this, there is a free alternative, in the form of Samba. While Samba 3 has been happily providing authentication along with file and print sharing to Windows clients for many years, the Microsoft world has been slowly moving toward Active Directory (AD). Meanwhile, Samba 4, which adds a free reimplementation of AD on Linux, has been increasingly ready for deployment. Three short talks at FOSDEM 2018 provided three different views of Samba 4, also known as Samba-AD, and left behind a pretty clear picture that Samba 4 is truly ready for use. I will cover the first two talks in this article, and the third in a later one.

  • A report from the Enigma conference

    The 2018 USENIX Enigma conference was held for the third time in January. Among many interesting talks, three presentations dealing with human security behaviors stood out. This article covers the key messages of these talks, namely the finding that humans are social in their security behaviors: their decision to adopt a good security practice is hardly ever an isolated decision.

    Security conferences tend to be dominated by security researchers demonstrating their latest exploits. The talks are attack-oriented, they keep a narrow focus, and usually they close with a dark outlook. The security industry has been doing security conferences like this for twenty years and seems to prefer this format. Yet, if you are tired of this style, the annual USENIX Enigma conference is a welcome change of pace. Most of the talks are defense-oriented, they have a horizon going far beyond technology alone, and they are generally focused on successful solutions.

  • DIY biology

    A scientist with a rather unusual name, Meow-Ludo Meow-Meow, gave a talk at linux.conf.au 2018 about the current trends in "do it yourself" (DIY) biology or "biohacking". He is perhaps most famous for being prosecuted for implanting an Opal card RFID chip into his hand; the Opal card is used for public transportation fares in Sydney. He gave more details about his implant as well as describing some other biohacking projects in an engaging presentation.

    Meow-Meow is a politician with the Australian Science Party, he said by way of introduction; he has run in the last two elections. He founded BioFoundry, which is "Australia's first open-access molecular biology lab"; there are now two such labs in the country. He is also speaks frequently as "an emerging technology evangelist" for biology as well as other topics.

  • Notes from FAST18

    I attended the technical sessions of Usenix's File And Storage Technology conference this week. Below the fold, notes on the papers that caught my attention.

Red Hat: Boston, US Government, OpenShift Route, VirtualBox and More

  • BU Spark! teams up with Red Hat, hosts software design workshop
    Students traveled across Boston to its Fort Point neighborhood to attend a BU Spark! workshop about interaction design Friday. There they delved into interaction design and explored how to develop user-friendly software. BU Spark! and Red Hat Inc. hosted the Interaction Design Bootcamp jointly at Red Hat’s Boston office. BU students and Spark! Interaction design fellows attended. Red Hat is a software company that specializes in information technology and has a research relationship with Boston University that includes educational elements. The programs taught by Red Hat focus on user experience design, one of Red Hat’s specializations, according to their website.
  • Open source can spark innovative business transformation in government, Red Hat leaders say
    The federal government, largely hamstrung by legacy systems, is in need of a major digital transformation. Open source technology can be the spark that sets off that revolution, leaders from open-source software company Red Hat said Tuesday. “The types of technologies that you choose matter,” said Mike Walker, global director of Open Innovation Labs at Red Hat. “It will influence the way your business operates and open new doors to new business process, and ultimately allow you to become a software company that can achieve some of those innovations and reductions in cost and time.”
  • Kubernetes Ingress vs OpenShift Route
    Although pods and services have their own IP addresses on Kubernetes, these IP addresses are only reachable within the Kubernetes cluster and not accessible to the outside clients. The Ingress object in Kubernetes, although still in beta, is designed to signal the Kubernetes platform that a certain service needs to be accessible to the outside world and it contains the configuration needed such as an externally-reachable URL, SSL, and more. Creating an ingress object should not have any effects on its own and requires an ingress controller on the Kubernetes platform in order to fulfill the configurations defined by the ingress object. Here at Red Hat, we saw the need for enabling external access to services before the introduction of ingress objects in Kubernetes, and created a concept called Route for the same purpose (with additional capabilities such as splitting traffic between multiple backends, sticky sessions, etc). Red Hat is one of the top contributors to the Kubernetes community and contributed the design principles behind Routes to the community which heavily influenced the Ingress design.
  • VirtualBox DRM/KMS Driver Proceeding With Atomic Mode-Setting Support
    The "vboxvideo" DRM/KMS driver for use by VirtualBox guest virtual machines that has been part of the mainline Linux kernel the past several cycles will soon see atomic mode-setting support. Hans de Goede of Red Hat, who has been stewarding this driver into the Linux kernel after Oracle has failed to do so, is tackling the atomic mode-setting as his latest advancement to this driver important for a VirtualBox desktop VM experience. Published today were initial patches preparing the move to atomic mode-setting but not yet the full migration to this modern display API that offers numerous benefits.
