UNIGROUP GENERAL MEETING
Unigroup's November 2019 meeting will discuss AFS - The Andrew File System, a distributed filesystem which now has some built-in out-of-the-box support in Fedora 31. AFS was developed back in the 1980s, and the open source OpenAFS project was formed back in year 2000. AFS has been available for a broad range of heterogeneous systems including: UNIX, Linux, MacOS X, and Microsoft Windows.
Our speaker, Jeff Altman, had last presented AFS-related topics to Unigroup back in 2011 (and 2005 before that), and his other Unigroup talks included: MIT Kerberos 5 (2004) and Security Protocols and Technologies (2001).

Topic: Linux Kernel AFS (Distributed Filesystem) on Fedora 31.
AFS, Andrew File System, AFS3, OpenAFS, AuriStor File System, Global File Namespace, Wide Area Distributed File System, Linux Kernel, AF_RXRPC, kAFS, Fedora Linux, Cloud Era File System, Containers, Linux Namespaces, Federated Authentication, Combined Identity Authentication, Constrained Elevation Multi-factor Authorization, GSS-API, Kerberos, Linux Keyrings.
Introduction & Description of Talks:
This meeting will be exploring some old technologies, some new implementations and the reasons why the ACM's 2016 Software System Award went to the developers of the Andrew File System (AFS). Thirty four years after the /afs file namespace went into production, Fedora 31 became the first Linux distribution to ship a complete Linux kernel AFS client solution. Unlike the monolithic AFS clients that originated with IBM AFS, Linux kafs is a modular Linux specific AFS and AuriStorFS client. Many of the components developed for kafs have become core Linux technologies including Keyrings, FS-Cache, and keyutils. With built-in support for Linux namespaces kafs provides one of the best solutions to address secure persistent storage for Linux Containers and implementation of portable overflow compute models.

Jeffrey Eric Altman, Founder and CEO, AuriStor
Jeffrey has developed data communications, distributed file system and network security solutions for more than thirty years. His experience with secure data communications extends from two-pair circuits to interplanetary transmissions.
Jeffrey founded AuriStor, Inc. in 2007 to extend the AFS concepts of WAN file system namespaces, security first network protocols, and access control to all 21st centry applications and end users. Today, AuriStor is setting a new standard for secure high performance globally accessible general purpose file systems.
AuriStor, Inc. produces secure, scalable cloud storage solutions that reduce the cost of managing the ever increasing unstructured storage needs of global enterprises, small & midsize businesses and eventually, individuals. AuriStor envisions a world in which all users experience the benefits of a universal globally accessible file namespace that provides all of the capabilities and performance of local disk file systems. In this world, operating systems, applications, and user data are executed locally for performance but are logically managed in the network simplifying hardware replacement, reducing risk of data-loss, improving accessibility, providing new opportunities for collaboration, application development and business models.
The AuriStor principals have worked together for over twenty years on Internet-based network file system and security technologies. These collaborations have led to the delivery of successful storage and security solutions to multiple industries, including finance, high performance computing, government research, and computer industry leaders including Apple and Microsoft.
The U.S. Department of Energy awarded Small Business Innovation Research grants in 2008 and 2009 to develop the AuriStor File System. Revenues are generated from software licensing and support contracts in multiple markets such as research organizations, academia and high finance.
AuriStor team members utilize our technology to successful collaborate from multiple locations. Headquartered in New York City, AuriStor team members reside in New York City, Cambridge MA, Edinburgh Scotland UK and Nova Scotia Canada.

Addison-Wesley Professional/Prentice Hall PTR/Pearson, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.
Unigroup would like to thank both publishing companies for the support provided by their User Group programs.
As always, all of the books will be available for review at the start of the meeting.
Note: Our book supply is currently running low, and we need to restock.
