Welcome to the TriLUG home page. We are a LUG dedicated to the Triangle area including Durham, Raleigh, Chapel Hill, and Research Triangle Park. This site, along with our wiki, will enable you to keep abreast of TriLUG information (meetings, events, news), and to communicate with local Linux and FOSS (Free and Open Source) enthusiasts.

The primary modes of interacting with us: mailing list, IRC, or coming to the monthly meetings.

October 8 meeting - Linux High-Availability

Mon, 2009-10-05 22:20

Linux is a very popular choice for server applications, but many businesses require extremely high availability. For example, phone companies require "five nines" of availability. That's 99.999% uptime.

Sure, my desktop PC might go a month or two between reboots. But how do you ensure that your Linux-based application is available ALL the time?

"Linux HA" is a set of tools that allows you to cluster several Linux systems together to provide a very high level of availability. When one system is not responding, the next one takes over.


September 10 meeting - So, You Think You Want to Start an Open Source Business

Mon, 2009-08-24 09:21

NOTE - There was some concern that our speaker might not be able to make it on Thursday night, but we have confirmed that the presentation will proceed as originally planned. - Alan Porter, 9/8 10pm

In 2002, Tarus Balog took a leap of faith by leaving his steady day job and taking over the management of a software package called OpenNMS. He has managed to slowly grow his business by providing support for this open source package, and by following the mantra "spend less than you earn".

Tarus will share his experiences with open source business, how it is viewed by customers, competitors, contributors and leeches.

And if you've got this lingering feeling that you could participate in the open source world and make it your full-time profession, Tarus has plenty of advice. Come join us for an unforgettable talk.


August 13 meeting - Drupal

Sun, 2009-07-26 21:29

Our very own Allen Freeman will be discussing Drupal, a very popular content management system (and if you're reading this notice, then you're seeing an example of it in action).

Find out how to set it up, what it can do, why you'd want to use it.

(1) Design a web page using Drupal. (2) ??? (3) Profit!

July 9 meeting - The Semantic Web

Tue, 2009-06-30 21:47

Please join us as Phillip Rhodes gives us a glimpse into the future of the internet - the Semantic Web.

The Semantic Web is the name given to Sir Tim Berners-Lee's vision for the next generation of the World Wide Web. On today's web, most data is provided in a format which is easy for humans to understand, but which computer programs have trouble understanding. This makes it difficult for us to program computers to perform useful, time-consuming tasks for us, using data retrieved over the Web.


June 11 meeting - Unbreaking Linux Audio

Wed, 2009-05-20 12:55

Daniel Chen is a Master of the Universe. No, not like "He-Man". He contributes significant time to the Ubuntu project, helping make audio applications and infrastructure "just work". This is a huge undertaking, since there are so many sound card drivers and so many audio frameworks that have come and gone over the years. This work has earned him the title of MotU from the Ubuntu team.


May 14th meeting - LinuxDNA

Sun, 2009-05-17 21:43

Tyler McAdams has been researching ways to fine-tune systems to run extremely fast. He is involved with a global project called "LinuxDNA", which aims to optimize the binaries which run on a machine, with special emphasis on the kernel. His team employs a compiler from Intel that is very good at producing optimized code for the x86 family of processors.

Bonus points if you can tell which distro Tyler likes to run (see below).

Come hear Tyler tell his secrets and his war stories about making Linux run FAST.


April 9th meeting - Lightning Talks

Sun, 2009-05-17 21:40

The April meeting will be a chance for members to share tips and tools with each other, in the form of "Lightning Talks". Each speaker will be given 10 minutes to discuss an indispensable tool to the group, including time for questions. Bring your ideas, and be ready to "share and enjoy".

March 12th meeting - Geographic Information Systems

Sun, 2009-05-17 21:31

WHAT: March TriLUG meeting
WHEN: Thursday, March 12th, 7:00pm
WHERE: Red Hat HQ, NCSU Centennial Campus
MAP: http://www.redhat.com/about/contact/ww/americas/raleigh.html

This month, our very own Doug Newcomb will give us an introduction
to the fascinating world of Geographic Information Systems. It's
the ultimate form of representing the world around us using computers.
Literally, we're mapping out our entire planet for use online.

We've all used Google Maps and Mapquest. But have you heard of the
collaborative effort at OpenStreetMap.org [1] to produce a complete


So you think you've been rooted...

Sun, 2009-03-01 12:00

Since we had a break-in on pilot recently, I thought I would bring up a
couple of points.


First of all, it appears that what happened to pilot was that a
vulnerability in "RoundCube", a fancy web mail package, was exploited by
a script that installs a "bot" (part of a botnet).

As far as I can tell, no files or emails were damaged. Everything
appeared to be intact. It looks to me like it was just talking to a lot
of other machines via an IRC channel (and that's how we noticed it).

The bot was running as user 'www-data'. So technically, we were not

February 12th meeting - CA Cert

Mon, 2009-01-12 22:46

CAcert.org is a community-driven certificate authority that issues free public key certificates to the public (unlike other certificate authorities which are commercial and sell certificates).

At the February TriLUG meeting, we will learn about certificates and certificate authorities, and we will have a chance to become "certified" to issue our own certificates through CA Cert. These certificates can be used to enable SSL on a web server or a mail server.
