Setting up an EeePC for gathering heat map data ¶

INTRODUCTION ¶

Ubuntu 10.10 ships with a fairly old version of kismet (2008 vs 2011), which is a pain to configure and not compatible with the latest gpsd in the repository.

This guide will help you configure Kismet to be used with a external GPS dongle. In this case the external GPS dongle is a Android Phone running the application BlueNMEA.

If you are using a serial or USB GPS dongle, you can skip the setup of bluetooth GPS and make sure to replace /dev/rfcomm0 your /dev/ttyXXX, e.g. /dev/ttyUSB0.

Good luck! Any questions? Rick van der Zwet <info@…>

INSTALL KISMET ¶

$ sudo apt-get install libncurses5-dev build-essential libpcap-dev libnl $ wget ​http://www.kismetwireless.net/code/kismet-2011-03-R1.tar.gz $ tar xvzf kismet-2011-03-R1.tar.gz $ cd kismet-2011-03-R1 $ ./configure --prefix /opt/kismet $ make $ sudo make install

INSTALL BLUETOOTH GPS ¶

$ sudo apt-get install bluez
# Find the MAC-ADDRESS you need, I have 38:E7:D8:C3:6B:C6
$ sudo hcitool scan
$ sudo hcitool cc MAC-ADDRESS
$ sudo hcitool auth MAC-ADDRESS
# Find the channel the GPS serial is 'working' on
$ sudo sdptool browse MAC-ADDRESS

# Configure your rfcomm config file
cat <<EOF >> /etc/bluetooth/rfcomm.conf
  rfcomm0 {
    bind yes;
    device 38:E7:D8:C3:6B:C6;
    channel 29;
    comment "GPS Android";
  }
EOF
# Restart bluetooth, alltough not sure whether this is really needed.
$ sudo service bluetooth restart

# Attach your new Bluetooth serial device
$ sudo rfcomm attach all
# View if attached succesfully by displaying raw NMEA stream
$ cat /dev/rfcomm0
# If you like to close it (properly during shutdown).
$ sudo rfcoom release all

INSTALL GPSD ¶

# Re-configure GPSD and make sure to set device to /dev/rfcomm0
$ sudo apt-get install gpsd gpsd-clients
$ sudo dpkg-reconfigure gpsd
$ sudo service gpsd restart
# View status of GPS
$ xgps (or gpspipe -r if you only have a CLI)

STARTING KISMET ¶

# Edit the config file;
#   - make sure ncsource= is set to the right source/interface.
#   - Check your gpsdevice=/dev/rfcomm0 and gps=true
$ sudo vim /opt/kismet/etc/kismet.conf
# Now start the server, we are not using the adviced SUID-ROOT mode as this
# require hacking around in our groups, refer to the KISMET manual if you are
# going to run this in a production envirionment.
$ sudo /opt/kismet/bin/kismet_server
# If all goes well you will see messages passing like:
## INFO: Started source 'wlan0'
## INFO: Connected to a JSON-enabled GPSD version 2.94, turning on JSON mode
#
# Now start the client and see the visual output
$ /opt/kismet/bin/kismet_client
#
# HINT: Alternative GUI kismet applications to try:
#  - qkismet (Hard to compile)
#  - gkismet (FAIL Ubuntu 10.10 - require Gtk.pm, no longer in repos).
#  - kismon  (FAIL Ubuntu 10.10 - require champlain-memphis which is only
#  availble in next version)

TROUBLESHOOTING ¶

As a rule of thumb, follow all steps in the process which allow you to view the status and or result of a step and see if it completes succesfully.

• Using Ulysse Gizmos you can nicely see if your Android phone has a fix already.
