July Meeting Program

Okay, if you run a public DNS server you need to hear this months' presentation. This month we have a presentation on DNS Security Extensions by Jeremy Reed. Jeremy C. Reed is a NetBSD and DragonFly committer, board member for BSD Certification Group, and an ISC employee. His presentation will introduce the DNS Security Extensions (DNSSEC-bis). It will cover the need, creation, use, troubleshooting, and problems of DNSSEC signed zones. The presentation will also introduce EDNS0, new resource records, and DNSSEC related tools. The examples will be done using ISC BIND. Due to limited time, the lecture will be very introductory while still covering these many topics. DNSSEC extends standard DNS to add resource records and algorithms to provide source authentication (not encryption) for DNS. It is backward compatible, so non-DNSSEC systems can still use the normal DNS data.

The next CACTUS meeting will be held on Thursday, July 17, 2008 at 7:00 PM (doors open at 6:30 PM for pizza and informal discussion), at Mangia Pizza at the corner of Burnet Rd./Mopac service road and Gracy Farms Ln. (See end of newsletter for directions to the facility).

Directions to Meeting Location

CACTUS meets on the third Thursday of each month at the Mangia Pizza (Gracy Farms location):

Mangia Pizza - Gracy Farms
12,001 Burnet Road at Gracy Farms Ln.
Austin, TX 78758
(512) 832-5550
http://www.mangiapizza.com/33/Gracy_Farms.html

This location is approximately 2 miles north of our previous meeting location at ARL. Note that the Mapquest map on Mangia's web site is slightly wrong.

Mangia pizza is on the north-east corner of the Mopac service road and Gracy Farms Ln.

From 183 north of Duval Rd.:
Take the Duval Rd. exit on 183 and turn left onto Duval Rd. When you get to the intersection of Mopac (Loop 1) and Duval Rd., make the left turn as though you were going to get onto Mopac North (this is Gracy Farms Ln.). You will see Mangia Pizza in front of you to the left at the traffic light. Turn left and then make an immediate right turn into the little store cluster.
From 183 south:
Take the Burnet Rd. exit on 183 and head toward UT Applied Research Labs (ARL) as you would normally. Instead of going to ARL, continue on Burnet Rd. In approximately 2 miles, Burnet Rd. will fork - to the left will be Duval Rd. continuing straight will bring you to a traffic light (at Gracy Farms Ln.). You should see Mangia Pizza on your right. Continue through the traffic light and make a right turn into the store cluster.
From Mopac:
Exit at Duval Rd./Burnet Rd. From the south, continue on the service road. Continue straight at the traffic light to the next traffic light just a little bit further up. You will see Mangia Pizza in front of you to the left at the traffic light. Turn left and then make an immediate right turn into the little store cluster.

From the north, make a left turn onto Duval Rd./Burnet Rd. and then an immediate left turn (as though you were going to make a U-turn back onto Mopac) and there will be another traffic light where you will see Mangia Pizza in front of you to the left. Turn left and then make an immediate right turn into the little store cluster.

Note: If you pass Mangia Pizza, there is a U-turn on the left just a little past the store cluster. Follow the directions for Mopac coming from the north.
