Originally, ARPANET ran the Network Control Program (NCP). The NCP
had many limitations (including address space) and was in time superseded
by TCP/IP. However, users were reluctant to make the transition. So, in
1982, Vinton Cerf and Jon Postel brutally forced users to switch from NCP
to IPv4 by programming the Internet gateways to block all NCP traffic.
Now, almost 30 years later, it is the IPv4 address space that is
approaching exhaustion. If current IPv4 address allocation policy
continues, then IANA will allocate its last remaining /8 block in 2011-06,
and the RIRs will allocate the last of their IPv4 addresses in 2012-04. Yet
the demand for addresses will only grow due to the rapid proliferation of
hand-held devices and the ongoing roll-out of Internet services in the
third-world.
IPv6 is a complete rewrite that offers a vast address space, new
services, and solutions to old problems. Yet, as with the change from NCP
to TCP/IP, adoption has been slow due to inadequate transition planning and
lack of incentives to change---until recently. While it is unlikely that
someone like a Cerf or Postel will pull the plug, the ongoing demand for
addresses means increasing pressure to change.

Are you behind the curve?
Need to see the technology demonstrated?
Want to try it out on your laptop?
Surrounded by IPv4 equipment and need a way out?
Interested in certification?

LUG members and members of the general public are encouraged to
attend the IPv6 Install-Fest.
Objectives: The IPv6 Install-Fest is designed to:
1) demystify the IPv6 transition,
2) help attendees achieve connectivity, and
3) recommend steps towards certification.
Environment: The presenter will provide:
1) a Linux 2.6 box to serve as an IPv6 router,
2) an 8-port, level 2, unmanaged switch, and
3) a number of CAT5 Ethernet cables.
Attendees: Please bring:
1) your laptop running Linux 2.6,
2) a CAT5 Ethernet cable, or
3) (optionally) a wireless access point.

Device and Storage Management
10 a.m., 12 June 2010
Reston Regional Library

The 21st century has proved a challenge to traditional POSIX (UNIX) platforms. Limited device and platform-eccentric support has driven the hardware-agnostic Linux solution to a new set of universal tools to managing devices and storage. Most of these solutions are designed to be automated without configuration and intervention by home users, while very flexible and powerful for Linux system and network administrators and engineers.

In this presentation, Bryan J Smith will cover the the following details to managing devices and storage in 21st century Linux:

General concepts:

• Disk labels, aka partition tables, and disk slices, aka partitions
• Device and storage mapping and presentation, volumes and filesystems
• Universally unique identifiers (UUIDs), including those physical and logical
• Legacy to contemporary POSIX approaches, standards and best practices

Linux tools:

• How the Linux kernel handles character and block device for storage access
  and operations
• The Linux Ext2/3/4, XFS, GFS/GFS2 and other filesystems
• How the Linux userspace assigns and accesses device filesystem (/dev) and
  common tools (udev, multipath, etc...), including the device mapper (DM)
• The hardware-agnostic Linux Logical Volume Manager (LVM) disk label

This presentation will both cover the concepts and evolution of device and storage
management as well as real-world implementation in both home user and enterprise
solutions.

The twenty-first century has brought with it a disturbing loss of personal privacy. Communications are routinely monitored for content and traffic analysis can be used to determine which IP addresses are exchanging meaningful amounts of traffic. Onion routing is a technique by which a subset of all network nodes are tasked with relaying encrypted traffic for clients. Tor is a widely used implementation of an onion routing protocol which defends against traffic analysis
attacks; it also implements hidden services only reachable from within the Tor darknet. Tor is endorsed by a number of human rights and advocacy organizations, including as the Electronic Frontier Foundation, Reporters Without Borders, and Wikileaks.org. Tor is also used by the US Department of Defense and the US Military.

The presentation will describe the origins of Tor as well as how the darknet functions. The threat model Tor was designed under will be discussed, and a demonstration will be given of how to set up the client, middleman and exit nodes. A demonstration of how to set up a web server as a hidden service will also be given. Operational security for clients as well as routing nodes will be detailed.

Questions will be taken after the presentation.

Bio:
Bryce A. Lynch has worked as a system administrator, security engineer, and consultant for fifteen years in the public and private sectors. He is interested in cryptography, privacy and anonymity technologies, electronics, music of all kinds, security research and penetration testing. His other hobbies include designing and building synthesizers, constructing biofeedback devices, tailoring, and writing code that other people can't make heads or tails of. When stuck in traffic he has been known to sing beltway karaoke and hold animated conversations with himself as a problem solving technique. He is the partner of one wife,
no children or pets, seven computers, and too many books. His sense of humor is implemented in LOGO, and he is actually very shy.
