Lore Sjöberg wrote a nice bit for Wired online: How to Heat Up Geek Reality TV where he describes tv show concepts that would actually appeal to the techies and trekkies/trekkers in the audience. Funny stuff!

Wardriving results.. that 29th position was close a few times but the other WiGLE user uploaded new points right before I overtook him. After a few tries and with a detour through Nieuwegein I made it: back at 29th position. Barely: the difference is 8 networks with gps locations. Since the previous post about wardriving: 693 new networks with GPS locations.

Wardriving results still occuring, and a good score today because I rode through 'uncharted' parts of Lunetten, a part of Utrecht: 431 new networks with GPS locations in one bike detour. Current ranking at WiGLE is at 30, someone overtook me (not completely unexpected) although I am on the way back to position 29 again.

A great sample of the 'movie plot' way in which 'terrorism' is seen and handled: a Vancouver police computer crime investigator has warned about how the wifi network in the city can be abused by terrorists at the 2010 winter olympics. Yes, three years from now. Reading the original article in the Vancouver Sun makes it an almost funny story (from this distance) but the saddening part is that this detective is serious and the newspaper seems to take his story serious. Bruce Schneier has written a good response about it Movie Plot Threat in Vancouver. One good comment:
I think the Vancouver Police crime investigator watches too much "24".

Sometimes Debian makes me go "aaaargh" a bit. When I visited Paris and wanted Internet access, I found out the pairing between my phone and the laptop had gone bad (all errors). Trying to delete the pairing and setting it up again gave a problem: there is no working bluetooth-pin application at the moment. Due to the dbus package being in transition, an attempt to install bluez-pin results in bluez-utils being removed (which means there is no bluetooth stack left running to authenticate in the first place). Google-fu to the rescue: Impossible to do pairing in Kubuntu shows that ubuntu users have the same problem and Dan V posted a solution how to build the command-line passkey-agent from the bluez-utils sources and use that to get a pairing again. I'm not the only one frustrated, debian bug 382269 shows more frustrated users.

Back.. From a visit to Paris this time. A project at work got me an invitation to the Lucent Alcatel user conference in Paris (lots of voip stuff there, information on new stuff in voip) and Mirjam had the idea to add a few days in Paris to visit all those places you have to visit as a tourist there. And lots of other tourists did just that...

Other source of that headache: having a windows user manage his own .htpasswd file. At least, trying to enable this. 'We' (unix users) are used to htpasswd [-cmdps] passwordfile username being normal, but this was a case of "where do I click". And this seems to be hard: a program to open, edit (add users/modify passwords/delete users) and save .htpasswd files. So far the least problematic program for this task I found is htpasswdgenerator. One major issue was that this program only supports crypt() passwords in the 'Pro' version, and this is the default under unix (plaintext is not available in the unix version). The program isn't bugfree, it gives weird errors about its tempfiles.... pfff. Another program wanted complete control over both .htaccess and .htpasswd and an ftp account to upload files to the webserver. Uh, just write the .htpasswd file to the right path? Oh, and this all costs money.. 15 to 30 dollars for what is a bit of user-interface and minimal file handling.

Source of a minor headache today: mod_authnz_ldap in apache 2.2 not doing what I want until I read the small print in the docs. Hope this bit: mod_authnz_ldap, Apache 2.2 and allowing all ldap users helps other people fix this.

2007-02-13 mod_authnz_ldap, Apache 2.2 and allowing all ldap users 13 years ago
Finding the right way to configure mod_authnz_ldap in apache 2.2 to allow all valid ldap users gave me a bit of a headache until Simon Cozens pointed me in the right direction of the valid way to get this effect. It is mentioned in the documentation, see the bit about mod_authnz_ldap and require valid-user.

Because my google-fu failed to find this, here is the correct sample:

        AuthName "Informatica medewerkers en studenten"
        AuthType Basic
        AuthLDAPURL ldap://ldap.cs.uu.nl:389/dc=cs,dc=uu,dc=nl?uid
        AuthBasicProvider ldap
        AuthzLDAPAuthoritative off
        require valid-user
Yes, AuthzLDAPAuthoritative off looks odd, but it is the way it works.

So. Yes. Wardriving. Still doing it, but since I'm still back to using the USB cable for the gps, with the associated hickups, I'm not really making big tours to score extra networks and with all the restarts of wigle I upload a lot of tiny files. Which means previous results fade out of the wigle result page fast. Anyway, I'm still at position 29 in the rankings at WiGLE, and I found 974 new networks with GPS sofar in February.

Big Media DMCA Notices: Guilty until proven innocent by Ben Maurer shows how BayTSP does very little 'research' in trying to find 'illegal filesharers' on bittorrent networks. Sounds like nothing was learned since the letters representing Microsoft asking for "Office" to be removed from an ftp-site because OpenOffice was available for download. Via: Slashdot article "To Media Companies, BitTorrent Implies Guilt"

New irregular: Configuring ssh on a Netgear GSM7224 switch. One of those things you don't do too often and have to dig up bits of information on how to do it from varying locations.

Back from snowboard holiday in Morzine, France... didn't break anything, not too much muscle pains and we had a great time! And yes, there was enough snow on the pistes, thanks to the hard work of the people of the Portes du Soleil piste services.
