On Sunday we went on a nice bicycle tour. A bit over 80 kilometers. I brought the wardriving box along and logged the networks found and the gps track. But now I can do something really cool: I can plot the track on a map and put the results on-line thanks to OpenStreetMap. No hassle with 'illegal' map material. This makes this a great moment in open license map data for me. Steps to use an OSM export map in gpsmap (part of kismet). I added the line about the license for the openstreetmap data myself but I can imagine importing data from openstreetmap and correctly naming the source turning into a standard option in gpsmap.

I measured the power usage of the wardriving box. It uses a nice 420 mA. That is very nice, given that the alix.1c board, the wireless card and the gps receiver are all powered from this. In theory, this means the 2.2 Ah battery should be able to power it for over 5 hours.

Vanmorgen op mijn werkaccount spam van ff7.nl. Blijkbaar gericht aan studenten (nee dat ben ik niet meer). Ziet er uit als een idee van studenten voor studenten: je scriptie backuppen naar hun server en vervolgens kans maken die weer op te kunnen halen. Leuk idee, maar jammer van het spammen. Het is wel een internationaal gezelschap: het IP van de server 194.126.173.10 staat volgens whois op naam van een bedrijf Eureka Solutions Sp uit Warschau, Polen maar is in Nederland. Die server eros.e-dentify.nl wijst weer naar een Nederlandse hoster. Abuse afhandeling voor het Poolse bedrijf wordt gedaan door swiftnoc.com en die zitten weer in Engeland.

Martin Bril heeft zich niet helemaal aan mijn voorspelling van gisteren gehouden. Vandaag schrijft hij over de kans op rokjesdag vandaag. Misschien moet Martin Bril eens de Uithof in Utrecht bezoeken waar het volgens mij toch echt al gisteren rokjesdag was.

Weird wi-fi news: A new regulatory agency in Russia has decided every device with Wi-Fi needs registration.
registering a PDA or telephone would take 10 days. Then, only the owner of the device would be licensed to use it. Registering a Wi-Fi hotspot, on the other hand, would be more difficult. Anyone wishing to set up as much as a personal home-network would need to file a complete set of documents, as well as technological certifications.
Sources: The Other Russia: Russian Agency Demands Registration for all Wi-Fi Devices, Wifi net news: Russia Requires Wi-Fi Registration Glenn Fleishman is as always following the wi-fi news, Slashdot: Russia to Require Registration for Wi-Fi Use with the obligatory joke written as wifi-register.su.
To me it sounds like that new regulatory agency claiming its turf. In a way that will annoy a lot of users.

Het is vandaag rokjesdag 2008. Ik voorspel dat morgen bijna alle krantencolumnisten die zich dat kunnen veroorloven dit gaan opschrijven. Vooral Martin Bril zal dit nieuws niet onvermeld laten.
Dat u het even weet.

Wardriving results 28 March - 16 April: 2853 new networks with GPS locations noted at WiGLE. Most amazing was finding 505 new networks without moving the wardriving box one centimeter: the AMD_IBSS networks were showing up again when I had the wardriving box running overnight in the top window.

Found out why firefox didn't talk ipv6 by default: the same resolver bug that I saw before: the resolver prefers ipv4+rfc1918 addresses over ipv6. Fixed with some DNS magic. Some day I'll phase out NATted IPv4 addresses. Until then they are irritating.

Squid has always been my webproxy of choice. Especially at home where I need interesting proxy rules to access certain work-sites via a special route and I like to use the parent proxies of xs4all. But ipv6 support was always a problem in squid until I looked recently and found out that IPv6 support is now default in squid 3-HEAD. So I compiled it and started playing with the access-rules. What I want (ofcourse) is the dancing turtle of kame. I tried to get this by adding an acl ipv6space dst 2000::/3 and using this in specific cache_peer_access deny rules which now works after some trying. I also found that writing the acl for the local network correctly helped a lot: acl localipv6net src 2001:888:1011::/48 works, when I forgot one : at the end it didn't work and denied me access. Now to get firefox to use ipv6 to talk to the proxy...

Our bicycle ride Sunday was really 'dual-use' for me: I logged 218 new networks with GPS locations at WiGLE and I mapped some bicycle paths around Utrecht at openstreetmap.

Found out the hard way: in the innfeed.conf configuration file key bindaddress6 needs its value quoted. So now inn is feeding again.
