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.

Topic: 
Home Brew Lab Hack Night
Presenter: 
Mike Canada
When: 
Thursday, 18 May 2017 - 7:00pm to 9:00pm
Where: 
Caktus Group, 108 Morris St, Suite 2 Durham, NC (Next to Bullseye Bicycle)
Parking: 
Street parking

Bring your system down to Caktus Group and let Mike help guide you in how to set up your own Home Brew Lab. From installing the hypervisor, to spinning up VMs and maybe configuring a little virtual infrastructure, he'll be on hand to help kickstart your setup.

Note that you should bring a reasonably powerful system if you want to set up much more than a trivial lab.

Thursday, 11 May 2017 - 7:00pm to 9:00pm
Where: 
The Frontier, 800 Park Offices Drive, Durham, NC
Parking: 
Parking is free, onsite

Note
We will be holding our annual Steering Committee elections at the very start of the meeting.

Summary
In this talk, I will cover how you can create your very own lab for both testing and learning new platforms using freely available software. I want to share with everyone a way that you can have your very own test lab at home for little to no money. With this project, you can brew your own lab at home or work with only one "server" allowing you to test many OSes and networking configurations. I will discuss topics including: Why do a Home Brew Lab? What kind of hardware to you need? What virtualization platform? What kind of networking? I will also provide ideas on how to obtain hardware at reduced and sometimes no cost. I will present methods of acquiring various type of OS and software including VMWare, KVM, and Hyper-V. I will also discuss the implications of the licensing for each product.

Topic: 
Understand or Write a Basic SELinux Policy
Presenter: 
Brian Bouterse
When: 
Thursday, 16 March 2017 - 7:00pm to 9:00pm
Where: 
Caktus Group, 108 Morris St, Suite 2 Durham, NC (Next to Bullseye Bicycle)
Parking:

Writing or maintaining an SELinux policy can be a daunting task if you've never done it before. In this hands-on workshop, you will learn how to create a basic SELinux policy. You will also learn to debug SELinux issues while designing or maintaining a SELinux policy. Contributing to SELinux is a great way to become more familiar with how it works and make open source computing more secure.

A rough outline of topics will include:

* Basic examples and compiling
* Using the M4 Macro Language (Reference Policy language)
* Debugging SELinux policy issues
* Contributing policies and fixes upstream with SELinux
* Packaging your policy
* Decompiling policies
* Where to get help

I wrote and maintain the SELinux policy for an open source project, Pulp, and want to share the experience I had writing it. With some guidance it can be fun. I'm assuming users have Fedora or RHEL, but we can probably figure it out on other distributions too.

Attendees are encouraged to come with a computer and a desire to contribute to an open source SELinux policy. If you bring software that does does not run within a SELinux context already you could write a basic policy for it. You can also learn more about an existing policy that you did not write. We can fix SELinux bugs and improve existing open source policies.

Topic: 
Understanding SELinux for the Win
Presenter: 
Brian Bouterse
When:

Where: 
The Frontier, 800 Park Offices Drive, Durham, NC

Many thanks to Eric Leary of DataKraft for the excellent recording and editing work!

Summary
Do you find SELinux complex or confusing? Have you ever disabled it in production? Is your application compliant with SELinux? This talk will provide an introduction to SELinux including how it works and motivation for why it is important for secure systems. This does not require previous SELinux knowledge, but it will give the basic tools to analyze failures and understand the state of SELinux on a system for both sysadmins and developers.

Topics will include:

  • Why do we care about SELinux?
  • How SELinux Works
  • What is an SELinux Policy
  • Fixing SELinux Errors
  • CIL Language
  • M4 Macro Language (Reference Policy language)

Come learn about SELinux so you can work with it for the win.
