Decrypting WPA with AirPcap in Windows

A step-by-step guide to decrypting WPA with Wireshark and AirPcap in Windows.

Free Enterprise Search

If you follow this blog, you’ll know that I recently setup an Ubuntu box running Samba with a 2.7TB Raid5 array. Its job is to replace one of our 300GB Dell PowerVault 715N NAS boxes which has become full.

Finding files on our previous 300GB PowerVault was nothing short of a nightmare and, with such a vast amount of data on the new system, we have to ensure that information won’t get ‘lost’ as easily. Obviously proper structuring of directories through a bit of Information Architecture will help, but what we really need is a search facility.

As a small company with a limited budget, the search facility has to be affordable. In addition, it needs to be easily accessible to everyone in the network, preferably without installing extra applications onto client systems…

Windows XP won’t hibernate: Insufficient System Resources Exist to Complete the API

After upgrading my laptop to 1.5GB of RAM, it began to frequently refuse to Hibernate, giving an error message in the system tray reading: “Insufficient System Resources Exist to Complete the API”.

Digging around, I found this Microsoft Knowledgebase article, along with a patch, which, insanely, isn’t available on Windows Update. Grr!

It seems the problem is caused due to the fact that when instructed to hibernate, XP has to find contiguous free space equal to the amount of RAM installed in the system. Naturally, as RAM increases, this becomes harder. Why on earth it’s incapable of using non-contiguous space is beyond me…but maybe that’s what the patch solves 🙂

Strange network behaviour on XP

This is a curiousity rather than a true solution. This morning, on booting his PC, a colleague found his PC refused to browse websites and (apparently) would not connect to any network shares, yet it could FTP to an external website and ping/tracert google.com. After booting XP, and entering user details (“loading your personal settings…”) the system would idle until the network cable was pulled from the NIC. The only thing which changed is that I installed VMWare Server Console on the system the day before (not the server itself, so it shouldn’t have added virtual NICs or messed with settings).

I solved the problem by uninstalling the NIC driver and letting it re-install after a reboot, but I’d love to know what may have caused the issue!
