One power house with no team? - 20:46
Looking at the photos from the TTT at the tour last night it appears every photo of Silence-Lotto on the stage report has Cadel on the front of the train. So sure we all know he has been let down once more by a weaker team at the tour, I also admit I have not watched the full live coverage of the stage. I do however begin to wonder, did Cadel end up doing a huge amount of the pulls for the whole TTT and then pulled away from most of his team mates in the last km. That appears to be riding harder than the effort by Cancellara at the end for Saxobank.

I really feel sorry for Cadel, now with so many strong Astana riders way up in the standing it looks like it will be a difficult task to gain time.

Success with WPA2 - 17:58
After spending far more time than I should have I have finally found a working configuration for the ANU WPA2 secure wireless on Linux. I spent a lot of time reading seemingly endless Ubuntu forum posts going on about problems that could be wpa supplicant, network-manager or kernel driver based issues. Bugs concerning various complaints were being assigned to any one of those three things.

Due to concerns that my driver for the iwlagn driver could be bad I upgraded my laptop kernel to the Debian sid 2.6.30 packages, I also then downloaded the latest wireless kernel drivers and installed them. Also the three programs mentioned, iw (new interface to wireless stack in Linux), crda and wireless-regdb.

Eventually I am not entirely convinced those things helped, many forum complaints for Ubuntu and other systems said network-manager had issues and to try wicd. My initial efforts with wicd failed. Eventually while reading some efforts someone else had made to work out what was happening on their system I saw someone using the rather simple iwlist tool to scan for the capabilities of the secure access points.

When I did this I notice the ANU-Secure access points all advertised the following. 

IE: IEEE 802.11i/WPA2 Version 1
    Group Cipher : CCMP
    Pairwise Ciphers (1) : CCMP
    Authentication Suites (1) : 802.1x

I had previously been trying TKIP and WPA2 when I tried wpa_supplicant alone without a manager on top. WPA2 and RSN are aliases for each other in this instance. Anyway with the new drivers and the sid wpa_supplicant I was able to get a wpa_supplicant.conf with the following to work on ANU-Secure. 

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root

network={
   ssid="ANU-Secure"
   scan_ssid=0
   proto=RSN
   key_mgmt=WPA-EAP
   eap=PEAP
   pairwise=CCMP
   group=CCMP
   identity="u9999999"
   password="PASSWORD"
   phase1="peaplabel=0"
   phase2="auth=MSCHAPV2"
#   priority=1
}

Then I looked through the wicd templates for one that had the minimum needed and noticed the wicd PEAP-GTC template had the desired fields set. So now in wicd I can access ANU-Secure from the desktop with no problems. I really should test out older drivers and some other configurations, also try out network manager again I think. Works for now though, I can finally stop wasting so much time on this.
