Office 2003 and Activesync and You

I was at a client's place today and she had Outlook 2003. I set her up with POP3 and tried to do a send/receive and it said "send/receive finished," but nothing happened. The test message I tried to send was still in the outbox, and the inbox was empty.

This problem also made it impossible for her to run Activesync with her Windows Mobile PDA. Whenever I tried to set it up, a message box would come up and tell me to install Outlook, run it once, and then run the synchronization wizard again.

Well, lo and behold, this was a known issue with Outlook 2003. A simple upgrade to Office 2003 SP3 fixed the problem.

Only took me 3 hours to figure it out!

Aircrack Injection (Part 1)

First of all, if you don't know, Aircrack is a program that's used to crack encryption keys of wireless networks. My laptop has a Broadcom 4306 chipset, which has been hacked to death by Linux developers.

Starting with kernel 2.6.24, a different driver is used for Broadcom chipsets (the older one was based on Intel drivers, the new one I believe is based on MadWifi). The drivers in the new kernel support injection out of the box, but the older ones do not. I previously spent a lot of time patching the older drivers to support injection, and it worked well, until I upgraded to the new kernel.

At first, injection only worked if I moved my laptop very close to the wireless AP. That problem appears to have been corrected in the new 2.6.27 kernel.

For a long time, I thought injection didn't work at all in the new kernel because I was doing it wrong: I was trying to authenticate with my access point at home, which uses no encryption. Apparently, the AP you authenticate with using Aircrack has to use WEP. Then today I tried authenticating on my neighbor's WEP-protected AP (just to test it, of course :) and it worked!

However, before doing that, I worked hard on making a live Ubuntu Gutsy CD that includes Aircrack, Kismet, and the patched drivers. So for anyone that wants it, you can download it here!


I was recently generously given two WiLife surveillance cameras. One of them has a power adapter that doesn't work, so only one camera is useful to me.

Unfortunately, it appears I can only access the camera using Logitech's proprietary software. Opening the powerline networking adapter in Wireshark shows TCP activity on a bunch of random ports, but I can't gleam any useful information.

If you've had success with third party software and this product, I'd like to hear about it.

We Need to Teach Critical Thinking Again

One thing most people don’t realize about tech people that are roughly my age (plus or minus five years, let’s say) is how many of the dark ...
