2016-03-25 Out of the WiGLE top 100 1 year ago
Once I was quite high in the WiGLE stats but nowadays I only "wardrive" when I remember to switch on the WiGLE client for Android on possibly interesting trips. So from the top position of being at number 14 in the WiGLE stats in June 2009 I now dropped out of the top 100, I just saw myself at ranking 107.

Most interesting recent wardriving option was on our winter holiday to the Brandnertal in Austria. I brought some wardriving device on that trip before and this trip did not find a big number of new networks, but it did find a lot of new mobile phone towers since the previous trip probably was with the WiGLE app on the android tablet without mobile data support.

Wardriving results 4 January 2014 - 11 July 2014: 14481 new networks with GPS locations according to WiGLE.

I don't "wardrive" on purpose now, but I leave an android device running the wigle android app on trips that can be interesting such as during holidays.

When I get around to wardriving lately I use the wigle app for android, so I decided to repurpose the wardrive box as shednet computer. This will also mean I can stop using PLC network to link the shed computer to the rest of the network, replacing it with wifi. Using PLC offends the radio amateur in me and people at the radio club now ask me whether I dumped it already. So, time for different hardware which as a plus will also use less power.

I already built in a laptop harddisk in the wardrive box and removed the compact flash holding the wardriving box image (I'll save it so I can restart using the wardriving box if needed). The alix 1c can work nicely with an IDE laptop harddisk.

The laptop harddisk built into the ritchie mini-itx case

The installation will probably be done with a recent debian jessie distribution.

Plans for the new shednet computer include an ntp server, but since the current gps unit (gpskit) seems to fail after running for a few days in the test setup that may have to wait.

Wardriving results 14 September 2012 - 30 November 2012: 1811 new networks with GPS locations. Adding a tablet with Android and WigleWifi for Android makes wardriving easier.

I am one place up in the WiGLE wardriving stats again.

Interesting article/presentation: Pen tester builds wifi war-bike about a motorcycle with war-driving capabilities based on kismet coupled with a heads-up display driven via a Raspberry Pi.

The video in the article of the presentation is not very good, and I can't find a website about this project at the moment.

Wardriving results 1 June 2012 - 13 September 2012: 1513 new networks with GPS locations at WiGLE. Some of those are from leaving the wardrivebox at home in the attic which still finds new networks when left running for days. Others are from trips including walking trips.

Sophos the security company went warbiking in central London and found very high numbers of wireless networks, with parts still without any security or with bad wireless security. All explained with a nice youtube video which presents the results in a format even your neighbour who still relies on WEP can understand.

The Sophos warbiking project.

Found via Warbiking: WiFi hacken op de fiets - security.nl although I would avoid using the term 'hacking' for purely passive measurements.

Gepubliceerd door het Agentschap Telecom: Afhankelijkheid telecommunicatie neemt toe, kwetsbaarheid netwerken stijgt - Agentschap Telecom met de 'staat van de ether 2011'. Staat van de ether 2011 (PDF)

Wat mij (ook) opvalt in dit rapport is dat het AT ook onderzoek gedaan heeft naar het gebruik van de 2.4 GHz en 5 GHz banden voor wifi en daar plotjes van gemaakt heeft die aardig op wardriving maps lijken. De plotjes zijn wat meer 'heatmaps' dus zullen er wel 'aantallen draadloze netwerken per oppervlakte eenheid' geplot zijn.

Verder is het interresant leesvoer. Een ander opvallend item: de nogal plotselinge overschakeling van de Duitse landelijke DAB zenders van kanaal 5A (174.160 MHz–175.696 MHz) naar kanaal 5C (177.584 MHz–179.120 MHz) omdat 5A vlak boven de (Duitse) politie frequenties zit was in coördinatie met Nederland, omdat MTVNL een allocatie 5C had voor het gebied Noord-Brabant. Dat is 9C (205.584 MHz-207.120 MHz) geworden. In alle berichtgeving toen over de Duitse verandering heb ik niet gelezen dat de frequentie gecoördineerd is met Nederland. Aangezien MTVNL (toen) nog niet echt actief was konden ze makkelijk nog veranderen.

Wardriving results 28 November 2011 - 31 May 2012: 558 new WiFi networks with GPS locations according to WiGLE. I think this covers the period in which the antenna cable for the wardrivebox broke.

Wardriving results 26 September - 27 November: 2529 new networks with GPS locations. Wardriving uncharted or less charted parts of the city delivers a lot more networks at the moment than bringing the wardrivebox along on trips over mostly known roads. I took the wardrivebox along on a trip to Den Haag today but it seems that city is almost completely covered by quite active wardrivers. WiGLE.net wardrive map Den Haag.

Wardriving results 20 August - 25 September: 968 new networks with GPS locations according to WiGLE. Lots of small testruns for the wardrivebox I was working on. During the holiday I was the first wardriver to put Garderen, the Netherlands on the WiGLE wardriving map.

Found: a not so subtle wardriving antenna. I am very sure my wife doesn't want me to do something like this to our car.

Bij het testen van de nieuwe wardrivebox kom ik onderstaande netwerk tegen. Dit toont gelijk aan waarom een 'hidden SSID' niet werkt, binnen 10 seconden is de link tussen probe en hidden ssid gemaakt.
Sun Aug 14 18:23:22 2011 Found new probed network "Ga_zelf_internet_halen" bssid 00:22:69:xx:xx:xx
Sun Aug 14 18:23:32 2011 Found new network "<no ssid>" bssid 00:0C:F6:xx:xx:xx Crypt Y Ch 0 @ 0.00 mbit
Sun Aug 14 18:23:32 2011 Associated probe network "00:22:69:xx:xx:xx" with "00:0C:F6:xx:xx:xx" via data.
Maar naast deze omschrijving is de security ook WPA2, dus je kunt het niet zomaar misbruiken.

2011-08-14 A second wardrivebox build 5 years ago
A friend asked me to help him get his own wardrivingbox going. I had a harder time doing this than expected, so I decided to retrace the steps.

He had installed ubuntu 11.04 on it from usb stick. This wouldn't boot, the grub setup was al wrong. Fixing the grub setup still left it non-booting.

This time I had the Heavy Duty Boot Environment available to help me, since the alix.1c / alix.1d boards are quite capable of PXE booting. This didn't turn everything into a simple install-party as the via_rhine drivers in anything but the most recent linux distro give issues. So the complete pxe load via network works fine but after that the network drivers don't work, making it impossible to do an OS installation which I can reproduce.

Good (ab)use of the 8G memory and 64bit architecture of the home server greenblatt : plot wardrive maps of all years I've been doing that. In the first run gpsmap took up a maximum of 8115 megabyte memory and the system was actually using swap:
             total       used       free     shared    buffers     cached
Mem:       7929324    7885124      44200          0       1792      45276
-/+ buffers/cache:    7838056      91268
Swap:      1959888    1836416     123472
But! I get my maps.

Wardriving results 2 August 2010 - 30 March 2011: 3432 new networks with GPS locations according to WiGLE.

Yes, six months for a wardriving results update. Something to do with other priorities in life!
