Portland Linux/Unix Group General Monthly Meeting: an OpenWrt Clinic – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 A quick overview of the build system for OpenWrt on supported devices, followed by a demonstration of installation and configuration. If you have a device you'd like help installing OpenWrt on, bring it along, perhaps we'll have time to address it. At a minimum there will be a Watchguard Firebox M300. Russell Senior has been building OpenWrt from source for a variety of purposes since about 2006 and has considerable knowledge about the ins and outs and what-have-yous. For background, you can watch a presentation he gave at Open Source Bridge in 2014: https://www.youtube.com/watch?v=ZOsRAxToyiM (some of the information in that talk from a decade ago is stale, so beware) |

PLUG/Perl: Indexing CPAN – Jax Bar (CLOSED) Speaker: brian d foy Topic: Indexing CPAN BackPAN is the historical archive of the Comprehensive Perl Archive Network, where most Perl modules live. Going back to 1993, BackPAN has about 100,000 distributions, taking up 12 GB of space. So far, there has not been a comprehensive index of all of these distributions. I'm working on a project to go through each distribution, record as much information as I can, and store that in a way that other people can ask questions. The big goal now is to take any Perl module file you have installed locally and query my index to determine exactly which distribution it came from, when it was released, what other files came with it, and at the time of it's release what its dependency list was. My talk is a demonstration of what I have so far, which is still in the data collection phase. I have an indexer that knows how to go through distributions and record information, and can do some with pluggable components for each portion of the work. In my talk, I'll demonstrate the current indexer and talk a little bit about the tools and techniques I use. There's plenty of cool Perl things going on, and I'm sure some of the Linux people will have valuable comments about software indexing. |

[Cancelled] PLUG Advanced Topics: FreeTUIT, Codeless GUI Programming – Jax Bar (CLOSED) Jax Bar 826 SW 2nd Ave Speaker: Eric Wilhelm Codeless GUI Programming A Declarative Syntax Layer for Desktop Graphical User Interfaces This will be the world premiere of a game-changing advancement in the development of desktop graphical user interfaces (GUIs). FreeTUIT removes the verbosity, tedium, and confusion from GUI development and provides a unified syntax for widget layout and configuration which supports good software design practice without getting in the way of rapid application development. FreeTUIT is a syntax and runtime for concisely declaring the layout and configuration of GUI widgets (such as forms, toolbars, buttons, and dialogs). The freetuit interpreter drives a unified object layer which is accessible from event callbacks. This takes you from a blank page to a static demo of the layout with zero setup and allows desktop applications to be developed and deployed faster than web applications by simply removing the HTML, CSS, XML, HTTP, Javascript, Database, Network, and User Agent components. |

Portland Linux/Unix Group: Intro to Digital Forensics – Portland State University FAB, Room 86-09
While it may not be as sexy as they make it look on TV, there are a number of powerful Open Source tools available for analyzing file systems and recovering data-- even data that may have been deleted by the attacker. This talk will start with an overview of the standard Unix file system architecture and discuss tools for imaging file systems, suggest a few useful tools and idioms for finding clues in your images, and cover how to discover "interesting" data from deleted files and re-assemble that data into an actual file image. Hal Pomeranz is the founder and technical lead of Deer Run Associates, and has been active in the system and network management/security field for over twenty years. As a senior member of the Faculty for the SANS Institute, Hal developed the SANS "Step-by-Step" course model and currently serves as the track coordinator and primary instructor for the SANS/GIAC Linux/Unix Security Certification track (GCUX). In 2001 he was given the SAGE Outstanding Achievement Award for his teaching and leadership in the field of System Administration. Note: |

PLUG Advanced Topics: DRDB HA Clustering on Commodity HW – Roots Organic Brewing [Out of business. *Sigh*] Using DRBD to Build High-Availability Clusters on Commodity Hardware Charlie Schluting of LINBIT will explain how DRBD works and how people currently use it, with enough information to get you started building your own clusters. DRBD stands for Distributed Replicated Block Device, and as the name implies, allows you to replicate block devices over TCP. DRBD is extremely flexible due to the fact it is a block device, and as such is used in a variety of situations. At the most basic level, you can replicate data between two servers to provide synchronously replicated storage redundancy for either failover or disaster recovery purposes. In active/active mode, you can also run GFS, OCFS2, or other clustered file systems. Topics that will be covered: - How it works, history, and future exciting news regarding mainline kernel inclusion - How it is used: HA-iSCSI, HA-NFS, Virtualization, Apache, Samba, etc. - Cluster Resource Manager options and recommendations, and news about the confusing changes in the Linux-HA / Clusterlabs communities. And the majority of the time will be spent on: - Example cluster configuration: hardware setup, installation and configuration, and cluster manager integration. Come with questions! |

Portland Linux/Unix Group: A Talk by Jeri Ellsworth – Portland State University FAB, Room 86-09 A Talk by Jeri Ellsworth (Circuit Girl) Jeri Ellsworth is a native Oregonian, born in Yamhill and raised in Dallas, Oregon. Early on she became fascinated with electronics and 8-bit computers setting the stage for her unique approach to learning. Not being challenged in school, she skipped higher education to pursue a career in car-racing and chassis fabrication. After that, she opened a chain of computer stores in Oregon and Washington. She sold those to persue a career in chip design, which lead her to design the CommodoreOne - based upon the Commodore 64 - using reconfigurable logic and the C64 DTV 30-games-in-one joystick, selling, a quarter million units. She currently works as an Oregon based consultant. I'm not sure what Jeri is going to speak about yet, but judging from the talk she gave at Stanford, it should be very good indeed. See a video of her Stanford talk at: http://video.google.com/videoplay?docid=-1053309060448851979# Also, see her webs sites at: http://www.jeriellsworth.com/ and http://www.fatmanandcircuitgirl.com/ |

PLUG Advanced Topics: What Went Wrong with My Disaster Recovery Plan – Roots Organic Brewing [Out of business. *Sigh*] Brian Martin will be test-driving his IEEE presentation on his experiences in a true, "abandon the building" disaster recovery effort. He'll place particular emphasis on where technically sound, well-tested disaster plans often fail in a real disaster, and how these problems can be overcome. The best data center disaster recovery plans are developed carefully and tested regularly. If you're at that stage, you may think you are well prepared. In this entertaining presentation, Brian Martin describes the unexpected problems that arose when a well thought out and tested plan met a real disaster, and draws lessons that are applicable to any disaster recovery situation. Brian Martin has spent 30 years in the IT field, fairly evenly divided between being a mainframe system programmer and a server system administrator. He has operated Martin Consulting Services in the Portland Oregon area since moving to Portland from the San Francisco Bay Area in 1996. He has a wife, two cats, a dog, and nine in-service computers at home. |

PLUG Advanced Topics: DRBD & Pacemaker part II by Adam Gandelman – Roots Organic Brewing [Out of business. *Sigh*] DRBD stands for Distributed Replicated Block Device. Mainline in the Linux kernel since 2.6.33, it is used to replicate data at the block level over the network in a "network RAID1" fashion. It is generally deployed as a cost effective, shared-nothing alternative to a SAN and used as the building block for high availability clusters. Pacemaker is currently the de facto open-source cluster resource manager (CRM) for Linux HA clustering. With it, nodes and services can be monitored and managed to ensure maximum uptime in the face of the most severe service and hardware level failures. Combining the two allows admins to %99.999 uptime at a fraction of the price of proprietary alternatives. In LINBIT's second PLUG Advance Topics installment, Adam Gandelman will give a more in-depth view of DRBD and Pacemaker and demonstrate how they work closely together to keep applications running and consistent. During the second half of the presentation, Adam will provide attendees with a real-world example by configuring a highly-available LAMP cluster from the ground up. Though geared toward web services, the concepts presented can easily be expanded to provide the HA gaurantee to virtually any Linux service. Agenda: - Brief re-introduction to DRBD, Pacemaker and HA clustering concepts. - Overview of various use cases and interesting deployments - Configuration and implementation of a highly-available LAMP cluster using DRBD for data redundancy and Pacemaker for resource management. Adam Gandelman is an expert in open-source clustering and high availability. Originally from New England, Adam lives in Portland, OR where he has been working at LINBIT, developers of DRBD and maintainers of Heartbeat. Aside from providing top-level Linux High-Availability and Disaster Recovery consulting for customers in the Americas, he leads LINBIT training courses in the US, doubles as a technical writer and regularly contributes to related open-source projects. |

Portland Linux/Unix Group General Meeting: Hacking on the Beagle Bone Black – PSU Maseeh Engineering Building Hacking on the new Beagle Bone Black Description: Russell recently spent some time working on porting a house-monitoring system from the Beagle Bone (an $89 embedded, ARM-based, I/O rich device running linux http://beagleboard.org/) to the new Beagle Bone Black, a $45 device which is faster, includes video and 2G of onboard flash. The sensors required a one-wire bus, one of which the original Beagle Bone had configured out of the box. The Beagle Bone Black had none. This talk is a description of what it took to get one-wire (specifically w1-gpio) going with his own custom "cape" (a daughter-board for the Beagle Bone). Biography: Russell Senior has been a GNU/Linux user for over 20 years, since the 0.99plN days, using it both recreationally and professionally as a research programmer/scientific data analyst. Since 2005, Russell has become involved as a principal volunteer with the Personal Telco Project (https://personaltelco.net), during which he has worked on embedded systems, primarily network routers. He contributes to the development and improvement of the OpenWrt project. In the last couple years, he has worked on monitoring systems involving Arduino and, since last year, the Beagle Bone and has learned a bit about the Angstrom distribution of linux for embedded devices.

Portland Linux/Unix Group: Virtual Private Networks – Virtual Private Networking Our illustrious IPv6 authority, Ted Mittelstaedt, will give a talk on popular Virtual Private Network options, including: 1) standard IPSec clients - require static IP at each endpoint, and are supported out of the box by Windows, Cisco IOS, Mac, and Unix using raccoon and similar programs. 2) Modified IPSec VPN clients - example is the Cisco IPSec VPN client. This is a proprietary modification used to allow one end to have a dynamic IP number. 3) SSL VPN clients. Cisco has one they call AnyConnect that is proprietary. OpenVPN is another example. 4) PPTP. This was supposed to have died years ago but since Microsoft ships the PPTP client with Windows it is still very useful in situations where the network admin is forced to provide VPN services to clients that she has no control over. 5) L2TP. This is what PPTP morphed into, Microsoft supports it natively, so it has the same benefits (to the network admin) as PPTP plus the Microsoft implementation allows for encryption using IPSec with certificates. Ted is the Co-Owner of Portlandia IT and author of the FreeBSD Corporate Networker's Guide Many attendees will break for a social hour at the Lucky Lab Brew Pub NW at 1945 NW Quimby See you there! |

Portland Linux/Unix Group Advanced Topics: Android App Collusion – Free Geek Who: Rogan Creswick The Android permission model opens up a number of opportunities for apps to bypass the established single-app permission checks that Android users rely on to control data flow and application behavior on their devices. I'll do my best to terrify the Android-using audience by describing the attack surface for colluding applications and showing interactive visualizations of multi-app data flow. We'll look at the Android permission model, the user-interface it results in, and I'll show just how easy it is to make apps that look innocuous. Bio: Rogan Creswick develops unique tools and techniques for software development and security analysis at Galois, Inc. His research interests focus on improving the state of the art in software engineering tools and user interfaces. His experience also reaches into the areas of user interface automation and customization via integrated assistants and automated documentation aides at IBM Research.

Portland Linux/Unix Group Advanced Topics: Speaking in Public is Easy – Free Geek Portland Linux/Unix Group Advanced Topics Meeting Announcement Who: Brian Rohan and Michael Dexter What: Speaking in Public is Easy Where: Free Geek, 1731 SE 10th Avenue, Portland (Left Entrance) When: Tuesday, January 21st, 2014 at 7pm Why: The pursuit of technology freedom You read that right: Speaking in public is easy and there is nothing stopping you from giving the next informative and compelling PLUG talk.
Brian and Michael will give you a pragmatic tour of exactly what is involved in open source conference speaking and explain precisely how nothing is stopping you from getting involved thanks to local organizations like the Portland Linux/Unix Group. Brian says: In 2007 I made the switch from being a machinist to a real estate agent, shortly thereafter I was invited to investigate a Toastmasters club, in order to become a better communicator. Through 5 years and over 40 speeches in Toastmasters I reached the highest level of Distinguished Toastmaster. Simply stepping out of my comfort zone has given me the opportunity introduce dignitaries, and MC fund-raising events for worthwhile causes (notably a record breaking Clark County Republican Party Lincoln Day Dinner auction). Currently I am a recognized top 2% leader in AdvoCare International, helping others achieve their physical and financial goals. I enjoy using Linux on a personal level for the freedom that it represents. "You never get rid of public speaking butterflies, you just get them to fly in formation: ~Marv Serhan Michael says: Never in a 1,000 years will I speak in public yet I find myself doing it several times a month in Portland and at conferences around the world. I guarantee I'm no Brian Rohan but I fill rooms and get applause. The secret is finding the right room and just doing it. I will talk about the absolute worst that can happen (rarely what you think it would be), the open source conference community and how to get from submitting a proposal to stepping down from the stage.

PLUG: Public Speaking is the Greatest Skill You Can Possess – PSU Maseeh Engineering Building The Portland Linux/Unix Group: Portland's monthly, three-track tech conference, celebrating its 20th anniversary this spring!
Brian and Michael are back to teach you everything you ever wanted to know about speaking at an open source from PLUG (hint hint) to OSCON. Brian has years as an experienced Distinguished Toastmaster (beer available at the Lucky Lab NW after the meeting) and Michael has just submitted his paper for the upcoming AsiaBSDCon conference on a topic he had previously known nothing about. Why should you give a talk?
Highlight from our Advanced Topics talk: (paraphrased) "My mom got more value out of learning to community with Toastmasters than two years of a (VERY impressive school) scholarship." YOU may change careers a dozen times in your life and need a new skill set for each job but will ALWAYS need to express yourself and communicate on behalf of yourself and your team. Let PLUG be that first step in what could be worth more than a (VERY impressive school) scholarship!

Dynamic Tracing with DTrace and SystemTap - Portland Linux/Unix Group Advanced Topics – Free Geek Daniel Hedlund will be giving an intermediate to advanced level talk on DTrace and SystemTap. DTrace (http://dtrace.org/blogs/about/) is a dynamic tracing framework, originally developed for Solaris, has been released under the CDDL license and ported to many other Unix-like OSes including FreeBSD, OS X and Linux. SystemTap (https://sourceware.org/systemtap/) provides similar functionality to DTrace but is Linux specific and released under the GPL. Dynamic tracing tools make it possible to safely inject instrumentation points (probes) into running applications on production environments; no recompilation is necessary and there is only minimal performance overhead when being used, and no overhead when not. Probes can be used to gather performance metrics to identify bottlenecks, create aggregate statistics such as the size distribution of filesystem writes, or to introspect arguments passed to individual functions in a running application without ever taking it offline. Many attendees will break for a social hour after the Third Tuesday meeting at the Lucky Lab on Hawthorne after the meeting PLUG: Portland's monthly, three-track tech conference!

Portland Linux/Unix Group: Security and OpenSSH – PSU Maseeh Engineering Building Who: Steve Dum What: Security and OpenSSH Where: PSU, 1930 SW 4th Ave. Room FAB 86-01 (Lower Level) When: Thursday, June 5th, 2014 at 7pm Why: The pursuit of technology freedom Stream: http://pdxlinux.org/live/ We will look at the security provided by OpenSSH and how the environment it is used in affects it's security. When can SSH security improve network security and when can't it. This presentation assumes you have a basic understanding of SSH and how it is setup. Those topics will be reviewed very rapidly as we dig deeper into the security aspects of SSH. The discussion concentrates on SSH authentication using asymetric or public key encryption. SSH is widely used to provide convenient and secure access to multiple machines on a local network, and to tunnel into remote networks to access machines on those networks that aren't directly visible to your local machine. We will analyze various use scenario's of SSH in these two usage scenario's and also the advantages and disadvantages of using an agent to facilitate SSH connections. For each of these scenario's, we will discuss the privacy aspects of one's passphrase and private keys, how secure the transmitted data is, and the ability of others to 'borrow' your credentials. You should walk away from this presentation with a better understanding of what actions you need to take to maximize your privacy, while reaping the benefits of using SSH. Many will head to the Lucky Lab NW at 1945 NW Quimby after the meeting. |

Portland Linux/Unix Group: Lowest Common Denomiator Coding with vi and sh – PSU Maseeh Engineering Building Who: Michael Dexter What: Lowest Common Denominator Coding with vi and sh Where: PSU, 1930 SW 4th Ave. Room FAB 86-01 (Lower Level) When: Thursday, July 3rd, 2014 at 7pm Why: The pursuit of technology freedom Stream: http://pdxlinux.org/live/ There are countless available text editors, programming languages and Integrated Development Environments (IDEs) but few are guaranteed to be present on any given system. On POSIX Unix systems, the vi(1) text editor and sh(1) shell are required by the POSIX (opengroup.org) standard and might be the only development tools at your disposal. While some developers may consider these tools equivalent to a doughnut spare tire that should not be used over 50MPH, others embrace them and have used them for decades. Some would also argue that you should learn the rules before you break them in order to appreciate higher-level languages. This talk will be a crash course in vi(1) and sh(1) with examples from a 2500 line virtualization management project that uses a number of scripting techniques. Michael provides independent Unix support and organizes PLUG. Many will head to the Lucky Lab NW after the meeting. |

Bring your laptop and an RTL-SDR dongle, HackRF, BladeRF, USRP, or other SDR hardware to this hack session and get expert help. Jared Boone and Kenny McElroy will be on hand to help install and configure software and explain concepts. Do try to install GNU Radio on your computer before you come, since it can be a long, slow process. If you get into trouble, we will do their best to get you unstuck. For those who come with GNU Radio already functional, we will advise you on things to experiment with. If you do not already own a software-defined radio, purchasing an RTL-SDR dongle from HackerWarehouse.com or NooElec.com is recommended. They are quite inexpensive ($15 to $20) but very functional and a great way to get started in software-defined radio. Bring some radio-based toys to hack on! If you can't make this meeting, be sure to watch Calagator, where Jared and Kenny will be starting an SDR meetup in the next few weeks. Jared Boone has an ongoing obsession with software-defined radio. He helped with the design and coding of the HackRF SDR and has done some privacy-related work, particularly around automotive tire pressure monitors. He is a frequent user of GNU Radio, baudline, and radio signal processing techniques. Kenny McElroy is a computer security researcher, focused on improving understanding and visualization of how the ones and zeros of computer security move around in the real world. Organizer's Notes: Ham Radio Outlet in Tigard has a number of good
magazines including the July/August QEX which features an article on GNU

PLUG Advanced Topics: CFPs from Announcement to Reimbursements – Free Geek Portland Linux/Unix Group Advanced Topics Meeting Announcement Who: Michael What's His Name CFPs or Calls for Papers/Participation are something you generally are oblivious to or schedule your whole year around. A CFP is what conference organizers use to formally announce their desire for speakers at an upcoming event. They often set guidelines and requirements for the talk and the organizers of successful conferences can find themselves rejecting hundreds of proposals. Michael will analyze a number of prominent open source community CFPs and will step through every stage of a CFP that requires an extended abstract, paper and presentation. Attendees will hear repeatedly how astonishingly easy some CFPs (like PLUG's) are to respond to and in will fact have their proposals ready by the end of the talk.

Portland Linux/Unix Group: Escaping GMail – PSU Maseeh Engineering Building Who: Louis Kowolowski If you’ve wanted to run your own mail server, but held back because it sounded complicated, fear no more. In mere days you too can have a GMail-like experience. Using common household tools such as Postfix, Dovecot, and MySQL, you can have a pointy clicky UI for your mail administration and webmail needs. I’ll be showing a demo that utilizes Postfix, Dovecot, PostfixAdmin, Sieve, MySQL, and RoundCube. Account manipulation (creating domains and users) through a webby, webmail, and server side mail filters. All of this is done on FreeBSD but can also be done on others such as Linux, Solaris, or even Irix (if you love pain). Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: The Future of Copyleft – PSU Maseeh Engineering Building Who: Bradley M. Kuhn Copyleft licenses, particularly the GPL and LGPL, are widely used throughout the Free Software community. However, recent for-profit corporate interest in Free Software development has led to a renewed preference toward non-copyleft licensing by for-profit entities. Meanwhile, many for-profit entities that do use copyleft for their own software now do so in a manner that most copyleft aficionados find, at best, distasteful and at worst, abusive. A long-standing truce exists in our community between fans of non-copyleft licensing and copyleft. No one in the copyleft communities disputes that non-copylefted Free Software is an important part of our community. However, copyleft faces new challenges that make past debates about the appropriateness of copyleft seem quite minor by comparison. This talk will discuss all aspects of the complicated situation facing copyleft, including younger developers apparent preference for non-copyleft licensing (as expressed, in part, in the "post-open source" debates), the widespread and common failures for companies to comply with GPL's relatively easy requirements, and how licensing choices are today, unlike in the past, rarely in the hands of individual developers, but instead their corporate employers. Bradley M. Kuhn is the President and Distinguished Technologist at Software Freedom Conservancy (sfconservancy.org) and on the Board of Directors of the Free Software Foundation (FSF). Kuhn began his work in the software freedom movement as a volunteer in 1992, when he became an early adopter of the GNU/Linux operating system, and began contributing to various FLOSS projects. He worked during the 1990s as a system administrator and software developer for various companies, and taught AP Computer Science at Walnut Hills High School in Cincinnati. Kuhn's non-profit career began in 2000, when he was hired by the FSF. As FSF's Executive Director from 2001–2005, Kuhn led FSF's GPL enforcement, launched its Associate Member program, and invented the Affero GPL. From 2005-2010, Kuhn worked as the Policy Analyst and Technology Director of the Software Freedom Law Center. Kuhn was the primary volunteer for Conservancy from 2006–2010, and has been a full-time staffer since early 2011. Kuhn holds a summa cum laude B.S. in Computer Science from Loyola University in Maryland, and an M.S. in Computer Science from the University of Cincinnati. Kuhn's Master's thesis discussed methods for dynamic interoperability of FLOSS programming languages. Kuhn received the O'Reilly Open Source Award in 2012, in recognition for his lifelong policy work on copyleft licensing. Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group Advanced Topics: FreeBSD Virtualization Options – Free Geek Who: Michael Dexter Learn about the latest developments in FreeBSD virtualization including EC2 and Hyper-V guest support, Xen Dom0 and DomU support and bhyve, the native FreeBSD Hypervisor. Learn about the latest developments in FreeBSD virtualization including EC2 and Hyper-V guest support, Xen Dom0 and DomU support and bhyve, the native FreeBSD Hypervisor. FreeBSD invented the modern Unix container with jail(8) in the year 2000 and today operates as an EC2 and Hyper-V guest, Xen Dom0 and DomU and now includes bhyve, the native FreeBSD Hypervisor. Michael wrote his first jail(8) management system in 2005 and has since operated NetBSD/Xen in production and was the first community user of bhyve, the FreeBSD hypervisor introduced with FreeBSD 10.0. bhyve is a modern, emulation-free hypervisor that relies on the Extended Page Table feature found in modern Intel and AMD CPUs. bhyve provides bare-metal performance for Unix virtual machines and an in some cases will in fact provide better than bare-metal performance. FreeBSD Xen Dom0 support has been many years in the making but is beginning to see the light of day. Michael is working with Xen developer Roger Pau Monné and aims to have a real-world report on the status of this unique effort. Combined, these technologies are establishing FreeBSD as an emerging first class virtualization platform with an increasing adoption by "cloud" service providers.

Portland Linux/Unix Group: Block Storage Device Life Cycles – PSU Maseeh Engineering Building Portland Linux/Unix Group: Block Storage Device Life Cycles Who: Michael Dexter Block storage has joined electricity as one of the fundamental technologies on which we are completely and irrevocably dependent. The two technologies are in fact becoming inextricable now that computers control virtually every electrical system from the distribution grids on up, and computers themselves are completely dependent on electricity to operate. Both technologies have undergone countless innovations yet still operate largely on their original basic principles. While high in capacity, fast and affordable, the modern hardware block storage device or “hard disk” operates on the same principles as the original 1956 IBM 350 disk storage unit and most solid-state alternatives emulate hard disks. Beginning with the Berkeley Fast File System, the BSD family of operating systems has played a key role in the evolution of general purpose block storage and continues this innovation with technologies like virtual block storage devices, GEOM, UFS2, ZFS, GELI, HAST, GEOM Journaling, FUSE, tmpfs and the NAND Flash framework. This paper will survey the available block device options in the FreeBSD operating system and explore their practical uses in modern storage architectures. FreeBSD is unique in that it provides the reference platform for the Unix File System and is now a tier one Zettabyte File System or ZFS platform. The 10.0 release of FreeBSD is particularly unique in that it includes in-kernel iSCSI network block device sharing, the NAND Flash framework, a FUSE implementation and the bhyve hypervisor which can leverage and help test most FreeBSD storage technologies. The FreeBSD ports collection also includes support for guest file systems such as ext2 and NTFS, which provide new opportunities to "round trip" virtual and physical machines using bhyve and tools such as the iBFT iSCSI boot framework. Finally, while an unprecedented block storage toolkit can enable extensive experimentation, there are pragmatic issues surrounding production storage architectures. This paper will touch on real world block storage solutions built with FreeBSD and its derivatives. These derivatives include the FreeNAS storage appliance, which provides networked block and file storage to a myriad of Unix and non-Unix clients. Pragmatic issues surrounding verifiable data integrity include: understanding and embracing ZFS behavior and limits, observing disk and partition health in addition to data integrity, understanding the implications of file naming, maintaining backups and restoring desired data in a timely manner.

Portland Linux/Unix Group Advanced Topics: Smarter S.M.A.R.T. and related storage challenges – Free Geek Portland Linux/Unix Group Advanced Topics Who: Roundtable discussion, moderated by Brian Martin and Michael Dexter We are addicted to storage devices like hard and solid state disks. Modern computing begins with storage and could survive quite some time without the computing part, as demonstrated by past storage devices like the Rosetta Stone for which we struggle to decode. This means HDD's and SSD's are reliable, right? Alas, they are not. In fact the situation is somewhat terrifying. File systems have made significant progress in the last decade but remarkably, there are still significant issues surrounding the devices they inhabit. Storage devices are inconsistent, to put it politely, about notifying the user of existing, potential and impending problems. Built-in, standard-ish reporting mechanisms like S.M.A.R.T. exist but pose as many challenges as they address. Some storage "health" monitoring data is straight-forward, some is not: https://www.youtube.com/watch?v=tDacjrSCeq4 Bring your storage-related questions, war stories and gadgets!

Portland Linux/Unix Group Advanced Topics: Linux as a security camera monitoring platform – Free Geek Who: Kevin Kaelar Setting up a camera in Linux is relatively easy. With any luck, you plug in the USB cable and it "just works". But what if you need ten cameras? What if you need to store increasingly large amounts of footage for liability purposes? What if you need to be able to access the realtime feed from any (or all) of those cameras from anywhere in the world? What if you need fine-grained motion detection for some of the cameras, scheduled recording capabilities for others at certain times of day, and provide varying levels of access to multiple users? This problem set is normally solved in a business environment by purchasing expensive (and frequently proprietary) security camera systems at a significant cost. However, it's possible to accomplish all of these things with a Linux-based application called ZoneMinder. During this talk, you'll be walked through the process of setting up a fully featured security camera and monitoring system, and will have the opportunity to learn about and/or discuss some of the supportive tech such as an Apache proxy, firewall and router configuration, and pruning and backing up video archives. About Kevin System administrator, game designer, software developer, open source contributor, Soylent drinker, wood carver, small electronics prototyper, blacksmith, poet, machinist, musician, and martial artist. Currently working as a full time web application developer for a music publishing company, Kevin spends most of his spare time babysitting a 3d printer and doing fun (and occasionally strange) things with Arduino at his startup in the Pearl District of Portland, Oregon. |

Portland Linux/Unix Group Advanced Topics – Free Geek Portland Linux/Unix Group Advanced Topics Meeting Who: Moderator Michael Dexter, PLUG Volunteer What's in a mirror? If you've spent any time GNU/Linux distro hopping or testing virtualization strategies, you have probably spent a non-trivial amount of time in the "nearest" download mirror. Such mirrors vary in speed, quality and navigability. The burden for upholding quality in each of these respects falls both on the often-volunteer mirror maintainers and the often-volunteer project maintainers. Failure from a mirror's perspective is obvious: You can't access the materials you want to download or what you download is corrupt. In the case of the downloads themselves, THIS: mirror.org/releases/amd64/20160704/livedvd-amd64-multilib-20160704.iso I was cleaning up my local mirror and came across this path and installer ISO and...

No privately owned network would voluntarily allow open-access, and hasn't since the DSL days (when they were required to), and the Feds, namely the FCC has been steadfast in its refusal to enforce line-sharing (essentially the same thing as open access) on infrastructure built since 1996. Many of you may have heard about the FCC action in December rescinding the relatively new Title II regulation of ISPs and the Network Neutrality rules that went with it. With the consciousness raising this event has provided, there is a new window of opportunity from the groundswell of interest to create pressure on our political systems, namely City Council in Portland OR, failing that, an initiative petition to provide a local solution. Russell will describe the problem and what a solution would look like, where the user ends up in the driver seat. Bring your Net Neutrality questions! Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Meltdown and Spectre Vulnerabilities – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Steve Dum Seemingly simultaneously multiple people discovered these vulnerabilities that exploit CPU data cache timing to cause protected information to be leaked. I'll start with a review of modern CPU design features like parallel execution, out of order execution, speculative execution, branch prediction,cache access and side channels leading up to the 3 flaws, called Meltdown and Spectre. Including a simple understandable example of the flaws, and show an actual Proof of Concept. Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Upgrading your business phone system with Asterisk – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Ted Mittelstaedt Most medium to larger businesses use central PBX phone systems to save money on telephone lines. Over the last decade the business PBX has gradually evolved towards Voice over IP hardware and away from traditional digital phones. Proprietary VoIP PBX systems such as Panasonic, Cisco and Mitel are available but costly. This presentation will cover how companies can take advantage of open standards such as SIP and LDAP and software such as Asterisk to have an inexpensive PBX that has features of the large, expensive and proprietary systems. An Asterisk system will be demonstrated and used as a sample system for the presentation. Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Combating global warming with open source and IoT – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Robin Haberman To fight global warming on the local level requires a change in thinking. We need to consider how new systems can be easily deployed and used by local groups. Supported by regional groups of academics, scientists, citizen scientists, journalists, environmental hackers, communities from the DIY and Maker movements. Systems that can aid local populations in their understanding of environmental and climate changes and help them deal with those changes. Our systems are aimed at the area that is the difference between today's weather and long-term climate changes ahead. These systems are designed to be the “last mile” of climate change monitoring, allowing local communities around the world to monitor their climate and take steps to mitigate changes. The systems will be owned and run by these communities with limited outside technical support, and can either stand alone or be tied together into an ad-hoc network similar to a small network of cellphone towers. Using our system to ask three questions: What is happening to our climate and environment? What does it mean? And what can we do about it? The hard data collected from the system, leaders in communities can begin planning how they will adapt and stay in place in their decision-making process. The GMIBS-Project will design, develop, and produce low-cost systems to aid local groups efforts to monitor and mitigate climate change. By this we hope to foster an ecosystem of users, developers, contributors, and competitors in an open global marketplace for climate change intelligent aid tool systems. About Robin Robin’s current work is on development of an Early Warring System for local climate changes. Graduated from a private high school housed at Reed College and staffed by students from Reed. His academic training includes several degrees with an international focus as well as information management and telecommunications (BS/AA and 3 Cert’s) Along with over 10,000 hours of professional training in intelligent networks and information storage, which gave him the skills and capabilities needed to work for two multinational and three foreign corporations. Other careers have been: Academic research for non-profit R&D organization; musical bands and llght show logistics. Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Open Source and POSIX Environments for Windows – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Michael Dexter Windows has a hard-earned reputation for appalling security and reliability but, better late than never, has matured into a relatively stable and secure desktop and server problem. Windows can run many popular open source desktop applications and has an incredibly-long history of on-again and off-again supporting Unix/POSIX environments such as Interix/SFU and Cygwin, and now ships with Linux emulation. These tools vary wildly in their depth of frustration to Unix users but do provide a gateway to some extremely-interesting yet intentionally-vague open source opportunities that will be demonstrated.

Portland Linux/Unix Group: PGP Key Storage with a Yubikey 4 – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Who: Russell Senior This presentation will walk through the use of a Yubikey 4 to hold an RSA PGP private key. Public key encryption requires protection of the private key. If control of the private key is lost, all reasoning about signatures and encryption is compromised. Storing private keys on a hard disk and processed by the PC makes the private key vulnerable to compromise. A Yubikey promises to key your private key secret. There will also be a digression during the presentation into so-called true Random Number Generators, e.g. ChaosKey and InfiniteNoise.

Portland Linux/Unix Group: Software Quality Engineering – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Who: Heather Wilcox There is no magic bullet for quality. Nor is there a right tool, script, or any amount of automation that can replace actual thought and effort. Building quality in requires that you first understand what it is. This talk will focus first on defining quality, then we will move to strategies for building the goodness in, and finally ways to test to ensure that both you and your "customers" are getting what they want. About Heather Heather Wilcox has spent 24 years working and learning in the software industry, choosing to focus primarily on start-up and small companies. As a result, she has had a broad range of job descriptions which include, but are not limited to: Tech Support Engineer, IS Manager, Technical Writer, QA Engineer, QA Manager, and Configuration Management Engineer. This has given Heather a wide range of experiences to draw from in her current roles as a Senior Quality Assurance engineer and Scrum Master.

Portland Linux/Unix Group: Why Packets Die – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Who: Tony Bourke Why do packets die? What happens inside data center switches and WAN routers that cause packets to die? In this talk, Tony does packet walks explaining in simple, relatable terms what happens when a packet leaves a server and doesn't make it's destination. Network congestion and its affects on buffering, queuing, QoS, rate limiting and shaping are all topics covered. Topics that can be scary to server administrators, but Tony breaks them down to very simple components. Also discussions on why protocol overhead doesn't much matter, and why jumbo frames don't matter to the network for performance are discussed. Tony Bourke is a networking instructor teaching primarily Cisco and related technologies. He is also a certified skydiving instructor and parachute rigger. He lives in Portland, Oregon but can be found all over the world teaching or skydiving (or both). Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Open Sourcing a Perl module – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Who: Andrew Hewus Fresh While I will explain about what DBIx::Class::Events does and how it works as well as some of the underlying technologies it builds on, this talk is primarily about open source contributions being driven by the folks in a company who care about them and how it is up to those people to provide the resources and knowledge to everyone else in order to create an open source culture in the workplace. As far as I know, no request to open source something has ever been denied by my employer, and while the company has always had the same "go for it" attitude, the folks writing code are only just starting to gain momentum releasing things publicly. I'll talk about showing other folks in the company the benefits of sharing code internally, how that exposed the benefits of open-source in general, and how we as a company progressed to getting DBIx::Class::Events onto the CPAN.

Portland Linux/Unix Group: Contending With Our Culture of Discouragement – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Who: You! The Free Software/Open Source community appears to be at a crossroads. A brave woman declared that "enough is enough" with the disturbing statements of a pivotal figure in the community and it rightfully cost that figure a number of prominent positions. Remarkably, she wasn't the first woman to challenge a foundation leader this year and help usher them to the door. Responses to such confrontations have ranged from false narratives to the proposal of morality-enforcing licenses for software. One theme however, is the chilling effect that disturbing, and at times unlawful behavior in the community causes, and the efforts to content with it. Why participate in communities with these issues? This passive discouragement is often combined with direct discouragement and countless forms of divisiveness. Yet we press on, and work to resolve these bugs, one by one. This meeting will be an open forum to share your experiences with discouragement in the free software/open source community. Trolls need not attend but will be educated by a panel of experts if they do. ATTENTION! Thanks to a new security policy, attendees will need to enter through the 1900 SW 4th entrance by 8PM, just North of the 1930 SW 4th entrance adjacent to Hawaiian Express, formerly Taco Del Mar: https://www.google.com/maps/place/1900+SW+4th+Ave,+Portland,+OR Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

Portland Linux/Unix Group: Glass Beatstation – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Athan Spathas Glass Beatstation: An open source mobile and modular musical interface for Linux machines and musicians that don’t know how to use Linux As a self-taught/amateur programmer, I was able to use open source programs to start building the versatile music workstation I’ve long dreamed of. The fact that I have been able to get this project functional to any degree is a great credit to the FLO (Free/Libre/Open Source) community. In the process I’ve learned about many of the benefits and learning curves of FLO hardware and software. I primarily used Python, Open-Stage-Control, Sooperlooper, Ardour, Puredata and the Kxstudio repositories, and have iterated an extra portable version of the project on raspberry pi. I will share the perspectives I have gained in the process how I was able to receive AND share knowledge with Linux users both new and experienced alike. Because of this, I’ve learned much about bridging the gap between those people already familiar with Linux/FLO technology, and those who aren’t familiar – yet. Athan Spathas teaches robotics to kids and supports open source software however he can: one is as likely to find him performing on his linux based portable studio as much as find him performing on it, doing demos, or educating others about the benefits of open source technology.

Portland Linux/Unix Group: Do you still use ASCII? – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Steve Dum A look at the journey from ASCII to UTF-8. I'll discuss the ramifications of the results of this journey for users and highlight cautions for developers. We have gone from the simple, a character is a byte, to a character may be tens of bytes, and worse monospace characters are not always the same width when displayed. This is a overview of features every GNU/Linux user should be aware of. It also highlights some issues programmers and sysadmins will face. I am a UTF-8 neophyte trying to fix a broken program that now needs to use UTF-8. I've spent decades porting large programs to new environments. Now I'm planning on integrating a large library to a small program. ATTENTION!

Portland Linux/Unix Group: Reading wireless temperature sensors with RTL-SDR and rtl_433 – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 Portland Linux/Unix Group General Meeting Announcement Who: Russell Senior
What: Reading wireless temperature sensors with RTL-SDR and rtl_433 Russell has been measuring an array of temperature sensors in and around his house since October-ish 2011, primarily Dallas Semiconductor DS18B20 one-wire sensors (previously talk: 2013-06-06 Hacking on the Beagle Bone Black). For years, he's had a few Oregon Scientific wireless temperature sensors outside, but no way to log the temperatures for posterity. About a year ago, in early December 2018, he discovered a project called rtl_433 that uses a software defined radio to receive and decode the signals coming from these and similar sensors. so that they can be logged. This talk will describe a few of the things that are possible with rtl_433 and what Russell does and doesn't do with the data. About Russell: Russell has been a Linux user since 1992. He worked for a few decades doing data management, programming, and analysis for a small scientific consulting firm. Since 2005 he has been deeply involved in the Personal Telco Project and trying to bring about telecommunications in the users interests, while also hacking on router firmware. For two years, he's been involved in an active effort to bring publicly-owned fiber infrastructure to the Portland metro area (in furtherance of the Personal Telco goal). He has a possibly unnatural love for serial consoles and RS-232, but is too smitten to be ashamed. He describes himself as self-under-employed. Will work on Linux'y things for money. Will work on Science'y/measurement'y things for money, as long as Linux is or can be involved somehow. He's very interested in trying to solve your telemetry problems with off-the-shelf wifi equipment and some elbow grease, if you've got some.

Portland Linux/Unix Group General Monthly Meeting: A Network Relay through a Cloud Instance; and Retro Linux Tape Recovery Show and Tell – Oregon Latvian Community Center Who: Russell Senior The first part is going to be a description of how I relay network connections from the Internet to my low-volume home-based email server to evade potential ISP blockages. The second part is going to be a show and tell about my resurrection of an ancient Linux version in order to recover data from Quarter Inch Cartridge tapes and ancillary topics. It will also include a short demo of my MS-DOS 5.0 environment also (resurrected from tape) the month before I installed Linux for the first time in December 1992. About Russell: I am a person for whom the Year of the Linux Desktop started in 1992 and has continued annually, uninterrupted. I worked for a couple decades in scientific data management and analysis. Since 2005, I have been involved with the Personal Telco Project, a volunteer-based 501c3 non-profit trying to unscrew telecommunications policy in the Portland metropolitan area. I did a short stint in data management for an Oceanographic organization when it was housed at OH&SU. I also volunteer at Portland State Aerospace Society working on their OreSat program. My name, misspelled in glorious circuit board silkscreen, has literally been in orbit for most of the last 2 years. I have done a bunch of PLUG talks over the years.

Portland Linux/Unix Group General Monthly Meeting: Ben Koenig on a Linux Changelog – Oregon Latvian Community Center Ever wondered how many package updates were released for your favorite distro in the past month? Or how many times you have had to upgrade Firefox? The Linux Changelog Project is an attempt to present statistics for the development and maintenance of Linux Distributions based on publicly available changelog data. By creating a distro-agnostic view of all changelog updates for a given project, we can see how the size and activity of a given distribution compares to its peers. At the moment only Fedora and Slackware are supported, but over time more distributions will be added. The end goal is to provide a web interface that will allow people to search for and browse the millions of package updates across all major Linux distributions. As someone who is largely self-taught in the world of GNU/Linux, projects like this are how I learn about the Linux ecosystem and practice skills that I apply to my career in IT support. While my experience goes all the way back to the dark days of HAL I'm still surprised by what I find hiding in the various corners of the Linux world. Working with the changelog formats of different distributions has challenged hat I thought I knew, and I hope other users (new and old) will find it interesting as well. |

Portland Linux/Unix Group General Monthly Meeting:OpenWISP, an Open Source Network Management System for OpenWrt – Portland State University Fourth Avenue Building (FAB) Room FAB 86-01 There are many commercial wifi access point (AP) controller setups, ie a single management interface to control multiple APs. Until recently there wasn't a FLOSS method of doing this. OpenWISP (https://openwisp.org/) is a modular and programmable Open Source Network Management System for OpenWrt. In this presentation we will go over the simple installation and setup process, including connection to multiple OpenWrt access points. Bio: Eldo Varghese is a constant nomad that has settled in Portland as of 3 years ago. Recently turned 40 and looking for more community in his old age. Currently works in an SRE/Devops role at a small non-profit academic journal (https://plos.org). Involved in Linux community in some fashion since 2007, and have used OpenWrt for the past 15 years. |
