Sun released the 2.0.2 maintenance release yesterday. Judging by the changelog it fixes a number of kernel related crashes of the guest os and a number of GUI crashes. Might be good to upgrade in other words.

Virtualbox 2.0.0 was released yesterday. Be sure to check it out at www.virtualbox.org.
A part from the GUI improvements it contains a couple of performance improvements and bugfixes. The complete changelog is here.
If you don’t want to end up loosing some work (as I did), make sure you don’t have any machines with their state saved (ie. make sure you shut all machines down) before you upgrade.

So I finally had some great success running airbase-ng as a rogue AP. I ended up buying the Alfa AWUS036H, an excellent 500mw Realtek 8187 based card. I am running a Virtual Gentoo system with the git version of the rtl8187 driver. The SKB BUF error messages from the aircrack-ng version of the driver where too annoying.
All in all I am very pleased with the setup, as it behaves consistantly now (knowing the needed tweaks to get it running). I believe it performs as well as running an AP with the madwifi-ng karma kernel patches from digininja. Well, except for one thing. When changing the MAC address of the wifi card it doesn’t really do such a good job anymore. For some reason most clients fail to associate, some still do but theres a considerable drop in the number of connecting clients.
I have tried to change the MAC using both ifconfig and simply specifying the -a option to airbase-ng. Sniffing the traffic using another wifi card shows a lot of probe requests and responses being re-sent, but no requests to associate. From my initial checks I do not see any difference in the requests or responses apart from the “Frame check sequence” and the MAC of-course. But then again, I haven’t put that much time into it.
ANY insight into why this happens, and if I am missing something REALLY obvious would be great. I will file a bugreport in the aircrack-ng TRAC system once I collect and clean the relevant packet traces.
