Abstract:

Cryptography has been in the news a lot lately. We'll start with a quick overview of some of the major recent headlines, specifically about the NSA's attempts to circumvent and break encryption and what experts are recommending to stay as secure as possible online. This will be followed with a high-level overview of cryptography. We'll look at where it's been made easy to use, and were it's not so easy. Then we will dig into the details of using GPG from the command line, to encrypt documents and to verify software packages.

October 10 Meeting: Choosing a secondary DNS server, now with data!

Mon, 2013-08-12 09:33

Topic: Choosing a secondary DNS server, now with data!
Presenter: Aaron Joyner
When: Thursday, 10th October 2013, 7pm (pizza from 6.45pm)
Where: NC State Engineering Building II Room 1025, Centennial Campus
Parking: The parking decks and Oval Drive street parking are free after 5pm
Map: Google Maps
Video: YouTube

Abstract:
Are you responsible for a DNS domain, perhaps professionally, or a "vanity" domain for your personal email?  Have you given much thought to the DNS resolvers for that domain?  Every domain requires at least one DNS server, and everyone has probably heard that they should have a geographically disparate secondary server to hedge against catastrophic outages (network, building, etc).  Assuming you don’t have the luxury of a globally distributed set of datacenters, where should your secondary DNS server be hosted?  This talk will present one man's quest to answer that question, along with the data used to visualize and understand the available options.  There will also be a brief discussion of how that data was collected, and open source code (in Go, http://golang.org) to do it yourself.

Michael Tiemann started the world's first open source software company, thereby placing the topic of open source into the field of economics.

Ignored for several years, open source has helped to rewrite the rules of economics, and has become an important subject among Nobel laureates. After reviewing 20+ years of Nobel Prize lectures in economics, Tiemann has synthesized a new perspective on the economics of cloud computing and the continued role that open source will play in the development of this new paradigm.

August 8 Meeting: Patents and Linux in Context

Keith will talk about intellectual property as a reality that shapes the context for open source software, particularly when overlaid against trends in technologies such as mobile and cloud computing, provide the history of Open Invention Network and its licensee community, and discuss Linux Defenders and other opportunities for community members to contribute proactively for the benefit of open source software.

Keith Bergelt is the chief executive officer of Open Invention Network® (OIN), the collaborative enterprise that enables innovation in open source and an increasingly vibrant ecosystem around Linux. In this capacity he is directly responsible for enabling, influencing and defending the integrity of the Linux ecosystem. Central to the achievement of his goals is the acquisition and transfer of patent rights designed to permit members of the Linux ecosystem to operate free of the threat of assertion and litigation from those whose business models are antithetical to innovation and global economic growth in information technology and computing.

July 11 meeting: Lightning Talks

Tue, 2013-06-25 15:27

Topic: Lightning Talks
Presenter: TriLUG Community
When: Thursday, 11th July 2013, 7pm

RSVP:
EventBrite (You don't actually need to bring a ticket to attend. Getting one just helps us prepare for refreshments so nobody goes without pizza!)

We'll be putting the July meeting in the hands of the TriLUG community by holding a series of Lightning Talks. Lightning talks are short talks of about 5-15 minutes long that give the audience a taste of a topic rather than going into the great detail associated with formal presentations. If you've been working on a cool project lately or learned something cool about technology, you are qualified to present something!

If you have an idea for a talk, please pitch it on the TriLUG mailing list and the community will help you cultivate it into a presentation you can be proud of. Prepend your subject line with "LT:" to make it easy to find (ie subject = "LT: Using Inkscape"). The Steering Committee will then collate a list of the topics and speakers from the mailing list posts. There isn't a set theme yet, but we expect a theme will emerge from the discussions in the next couple of weeks.

  • Cracking Password Hashes (Slides) - Scott Miller
  • Booting Linux on EFI using rEFInd - Matthew Frazier
  • Electric Cars and Open Source Cars (Slides) - Jeremy Davis
  • Network testing with iperf (Slides) - Bill Farrow
  • Networking Tools (Slides) - William Chandler
  • Flashback - a better way to backup -Alan Porter
  • Open Source Ecological Solutions - Moustapha Barry
  • Ceph storage platform (Slides) - Jack Hill

We are extremely fortunate to have Cathy Davidson speaking June 13th at TriLUG! Make sure you do not miss this rare opportunity! Cathy Davidson is an extraordinary individual and a brilliant minded speaker, who is a highly influential player in the world of open education in the universities.
She is the first educator to serve on the six-person Board of Directors of the Mozilla Foundation! She'll include in her talk, discussion of her two current peer-taught, peer-evaluated classes and her upcoming work to prepare for a Coursera MOOC entitled "The History and Future of Higher Education". Make sure your schedule allows for you to attend this special event. Also, spread the word to your fellow digerati and invite them to attend.

Please note that this meeting will be held at a new venue, so there will be some shifts in the usual schedule. NCSU does not permit food in its classrooms, so we are going to begin the meeting with a reception/networking over our usual pizza in the atrium of Engineering Building 2. At about 7:30 we'll move to 1021 to begin businesss, community announcements, and the presentation.

Steering Committee Elections

Mon, 2013-04-15 20:23

The Steering Committee Elections will be held at the TriLUG May meeting.

Nominations are now open, please help your local Linux community by nominating yourself or some unsuspecting TriLUG member. There are five hotly contested positions on the Steering Committee, and you could be one of them. Contenders will be able to give a brief stump speech at the May meeting to drum up support, and then we vote.

To vote or serve on the committee, you will need to be a TriLUG "member". If you filled out a membership form at the April meeting or before, your covered. If you have lost your card, don't worry, we have a mysql database to look you up. Voting will be performed by paper ballot during the May meeting, and you must be present to vote.

The Steering Committee is responsible for planning meetings, finding speakers, ordering pizza, paying bills. This year they will need to secure a new meeting location, file the 501(c)3 paperwork, and Get Stuff Done™.

This post from a couple of years ago has a nice list of things to do:

Topic: FreeIPA
Presenter: Jeremy Agee & Chris Hudson
When: Thursday, May 9, 7pm
Where: Red Hat HQ, NCSU Centennial Campus, 1801 Varsity Dr, Raleigh, NC

FreeIPA is an integrated Identity and Authentication solution for Linux/UNIX networked environments. A FreeIPA server provides centralized authentication, authorization and account information by storing data about user, groups, hosts and other objects necessary to manage the security aspects of a network of computers.

This talk will describe the different parts of IPA and what each one does:

  • What is an IdM system and why do i need one?
  • What do we need to manage?
  • overview of how do these parts work together NTP, LDAP, PKI, KDC, HTTPD, and DNS
  • client parts sssd, certmonger

The talk will then switch to a live demo of installing and configuring a FreeIPA server, and adding a client to the IPA infrastructure. The demo will cover CLI and Web UI for admins, dns management, krb5+nfs4 for file access, SSO for ssh + key management, and sssd caching for when IPA servers are unavailable (anyone use a laptop?).

If there is enough time after the demo, we can go into enterprise features like HBAC, sudo rules, Automount maps, selinux users, and AD cross-realm trusts.
