What is a WiFi Controller?

Feature freeze
Jan 24th
Some of us took the time last week to create something new. I chose to challenge myself by designing a system I had not built before and that I am not ready to share… quite yet. :) But I do want to share something about the design process in very general terms.
The lesson I learned: Feature freeze is a good thing. Know when to stop fixing.
Now early in the project, I had a pretty good idea of what pieces needed to go together but I did not have a very good idea of how to get there. I put down a quick design and while I was doing that I started to see problems..
- Pieces did not fit together.
- Some things were missing.
- This was not going to work.
Time to start learning. I love learning.
Debugging IPSec VPNs in FortiGate

Debugging IPSec VPNs in FortiGate
Debugging what is going wrong with a VPN setup is difficult. The IKE protocol is “chatty”, and negotiates back and forth between the two ends for several rounds. The GUI offers not much help, it is either UP or Down. Most of the real debugging happens inside the CLI.
One problem in particular that has always bugged me is that you need access to the end machines involved to initiate traffic across the link. The network admin typically doesn’t have direct access on the computers on either side of the VPN in order to initiate that traffic. I’ll show you a method that can be used to initiate traffic from that network as well.

FreeBSD 9 and ZFS version 28, THANK YOU!
Jan 18th
I’m excited! My favorite operating system, FreeBSD, has gotten an upgrade! There are a lot of small changes but the big one (the one that I’m excited about) is getting ZFS version 28 into the kernel.
ZFS Version 28 adds some of the more important features of ZFS: Deduplication, triple parity RAIDZ3, and RAIDZ. This means that I can have full featured storage devices, running ZFS natively, via FreeBSD.
As a bonus I don’t have to learn Solaris.
