Hi all,

first let me thank for this great tool. Although I am still not familiar with it, I think it will save me a lot of time. Let me start with my objective:

I have four identical APs (Buffalo G300NH2, Atheros Chipset) and flashed
them with the actual OpenWRT and installed Kismet_drone Version 2010-07-R1-1.

I want to make a localisation of _any_ Client, that is roaming around. Associated
with a certain AP or not. Therefore I need (in the first step) the SignalStrengh of all the client as it is seen from any of my four APs.

As far as I understood the Kismet Documentation, all this would be possible to set up... right?

My Drones are running (but I think there is something wrong..) and the Server
connects to them and receives Packages... everything seems OK, but now I am
stuck and really need some help.

First question:
Any of the drones fire the following ERROR on startup:

ERROR: Source 'mon.wlan0' doesn't have mac80211 support, disabling VAP creation
of default monitor mode VAP

But I am quite sure, that the mac80211 support is there... because:

root@OpenWrt:/etc/kismet# lsmod |grep 802
mac80211 228624 1 ath9k
cfg80211 136288 3 ath9k,ath,mac80211
compat 3200 1 mac80211

root@OpenWrt:/etc/kismet# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth0.1 no wireless extensions.

eth0.2 no wireless extensions.

br-lan no wireless extensions.

wlan0 IEEE 802.11bgn Mode:Master Frequency:2.457 GHz Tx-Power=19 dBm
RTS thr:off Fragment thr:off
Power Management:on

mon.wlan0 IEEE 802.11bgn Mode:Monitor Frequency:2.457 GHz Tx-Power=19 dBm
RTS thr:off Fragment thr:off
Power Management:on

Second question:
The logfile on the Server is growing, but I don´t know how to extract the
information I need (in realtime)... When I tcpdump it, I only see beacons,
and probes, but no information about any client that is around and its signal-
strength or SNR... AmI missing something? Do I have to filter something with tcpdump? If so, how would that filter look like?

Anyways, I would prefer the XML-Log, but the XML also only contains Information
about APs, nothing about the clients... how can I achieve that?

Thirs question...
Is there another way to receive the actual RF-situation in realtime on demand... currently I have set the logfile write interval to 1 second, but I´d really prefer to get the current state on a more elegant way, e.g. by connecting to the server via a port and get the XML (would be best)... e.g.
via a HTTP-Request sent to the kismet-server..??

Thanks again for reading and maybe trying to help me.
