S.C.A.L.E is coming! Feb. 19-21!

Sorry to take so long between posts… But I’ve been kinda busy getting ready for The So. Cal Linux Expo, coming up in Los Angeles February 19th through the 21st. This is the premier open source show on the west coast! I’ll be there as the network architect this year, with Mike Maki taking over my position as Tech Committee Chairperson.

This year, we are pushing the envelope by adding IPv6 connectivity network wide. As near as we all can gather, this makes us the first show of this type to provide a dual stack network show wide!

If you are in to opensource, or getting pressure to reduce your IT costs, come enjoy the show! A quick sumary:

• Over 80 exhibitor booths
• Over 100 talks and presentations
• B.O.F. events
• Gatherings and Fun & Games

See their web page for details http://www.socallinuxexpo.org.

Come be a part!

Hope to see you there.

How to build a Linux Firewall… Join us and Learn!

I will be speaking at the Simi Conejo Linux Users Group (SCLug) on August 15th 2009.

I will be demonstrating how to setup a Linux based PC with multiple network interfaces to act as a firewall. The presentation will cover the following topics:

1. Linux as a stateful firewall.
2. Using policy based routing to select between multiple  routes.
3. Performing source and destination network address translation.
4. Performing load balancing between multiple internet connections.

I plan to start with a base Debian install, and take the group step by step through setting up NAT for both static and DHCP internet connections. I’ll then move to setting up a second internet connection, and demonstrate the use of policy routing to choose an outbound route for different types of connections. Once we’ve covered policy routing, I”ll finish up with session based load balancing across both connections.

If you are going to be in the East Ventura County area on the 15th, I encourage you to join us!

The presentation will be held at the Simi Valley YMCA at 2:00PM on August 15th, 2009.

I look forward to seeing you there!

Notes From My KVM (Kernel Virtual Machine) Talk.

First of all, thanks to all who attended the SCLug meeting on Saturday. I had fun talking with everyone there.

I wanted to follow up with some written examples of the KVM command lines I demonstrated at the meeting. I know I seemed to go over this stuff kind of fast, so I wanted to elaborate a bit in text.
