Intel SSD 520 Series 180 GB with Lenovo firmware still lock up from sustained writes
-
10th July 2013
-

A few days ago, I wrote about -the -problems I experienced with my new X230 and its SSD disk, which -was dying during installation because it is unable to cope with -sustained write. My supplier is in contact with -Lenovo, and they wanted to send a -replacement disk to try to fix the problem. They decided to send an -identical model, so my hopes for a permanent fix was slim.

- -

Anyway, today I got the replacement disk and tried to install -Debian Edu Wheezy with encrypted disk on it. The new disk have the -same firmware version as the original. This time my hope raised -slightly as the installation progressed, as the original disk used to -die after 4-7% of the disk was written to, while this time it kept -going past 10%, 20%, 40% and even past 50%. But around 60%, the disk -died again and I was back on square one. I still do not have a new -laptop with a disk I can trust. I can not live with a disk that might -lock up when I download a new -Debian Edu / Skolelinux ISO or -other large files. I look forward to hearing from my supplier with -the next proposal from Lenovo.

The original disk is marked Intel SSD 520 Series 180 GB, -11S0C38722Z1ZNME35X1TR, ISN: CVCV321407HB180EGN, SA: G57560302, FW: -LF1i, 29MAY2013, PBA: G39779-300, LBA 351,651,888, LI P/N: 0C38722, -Pb-free 2LI, LC P/N: 16-200366, WWN: 55CD2E40002756C4, Model: -SSDSC2BW180A3L 2.5" 6Gb/s SATA SSD 180G 5V 1A, ASM P/N 0C38732, FRU -P/N 45N8295, P0C38732.

Good causes: Debian Outreach Program for Women, EFF documenting the spying and Open access in Norway
+
15th October 2013
+

The last few days I came across a few good causes that should get +wider attention. I recommend signing and donating to each one of +these. :)

+ +

Via Debian +Project News for 2013-10-14 I came across the Outreach Program for +Women program which is a Google Summer of Code like initiative to get +more women involved in free software. One debian sponsor has offered +to match any donation done to Debian +earmarked for this initiative. I donated a few minutes ago, and +hope you will to. :)

+ +

And the Electronic Frontier Foundation just announced plans to +create video +documentaries about the excessive spying on every Internet user that +take place these days, and their need to fund the work. I've already +donated. Are you next?

+ +

For my Norwegian audience, the organisation Studentenes og +Akademikernes Internasjonale Hjelpefond is collecting signatures for a +statement under the heading +Bloggers United for Open +Access for those of us asking for more focus on open access in the +Norwegian government. So far 499 signatures. I hope you will sign it +too.

Oslo community mesh network - with NUUG and Hackeriet at Hausmania
+
11th October 2013
+

Wireless mesh networks are self organising and self healing +networks that can be used to connect computers across small and large +areas, depending on the radio technology used. Normal wifi equipment +can be used to create home made radio networks, and there are several +successful examples like +Freifunk and +Athens Wireless Metropolitan Network +(see +wikipedia +for a large list) around the globe. To give you an idea how it +work, check out the nice overview of the Kiel Freifunk community which +can be seen from their +dynamically +updated node graph and map, where one can see how the mesh nodes +automatically handle routing and recover from nodes disappearing. +There is also a small community mesh network group in Oslo, Norway, +and that is the main topic of this blog post.

+ +

I've wanted to check out mesh networks for a while now, and hoped +to do it as part of my involvement with the NUUG member organisation community, and +my recent involvement in +the Freedombox project +finally lead me to give mesh networks some priority, as I suspect a +Freedombox should use mesh networks to connect neighbours and family +when possible, given that most communication between people are +between those nearby (as shown for example by research on Facebook +communication patterns). It also allow people to communicate without +any central hub to tap into for those that want to listen in on the +private communication of citizens, which have become more and more +important over the years.

+ +

So far I have only been able to find one group of people in Oslo +working on community mesh networks, over at the hack space +Hackeriet at Husmania. They seem to +have started with some Freifunk based effort using OLSR, called +the Oslo +Freifunk project, but that effort is now dead and the people +behind it have moved on to a batman-adv based system called +meshfx. Unfortunately the wiki +site for the Oslo Freifunk project is no longer possible to update to +reflect this fact, so the old project page can't be updated to point to +the new project. A while back, the people at Hackeriet invited people +from the Freifunk community to Oslo to talk about mesh networks. I +came across this video where Hans Jørgen Lysglimt interview the +speakers about this talk (from +youtube):

+ +

+ +

I mentioned OLSR and batman-adv, which are mesh routing protocols. +There are heaps of different protocols, and I am still struggling to +figure out which one would be "best" for some definitions of best, but +given that the community mesh group in Oslo is so small, I believe it +is best to hook up with the existing one instead of trying to create a +completely different setup, and thus I have decided to focus on +batman-adv for now. It sure help me to know that the very cool +Serval project in Australia +is using batman-adv as their meshing technology when it create a self +organizing and self healing telephony system for disaster areas and +less industrialized communities. Check out this cool video presenting +that project (from +youtube):

+ +

+ +

According to the wikipedia page on +Wireless +mesh network there are around 70 competing schemes for routing +packets across mesh networks, and OLSR, B.A.T.M.A.N. and +B.A.T.M.A.N. advanced are protocols used by several free software +based community mesh networks.

+ +

The batman-adv protocol is a bit special, as it provide layer 2 +(as in ethernet ) routing, allowing ipv4 and ipv6 to work on the same +network. One way to think about it is that it provide a mesh based +vlan you can bridge to or handle like any other vlan connected to your +computer. The required drivers are already in the Linux kernel at +least since Debian Wheezy, and it is fairly easy to set up. A +good +introduction is available from the Open Mesh project. These are +the key settings needed to join the Oslo meshfx network:

+ +

+ + + + + +
SettingValue
Protocol / kernel modulebatman-adv
ESSIDmeshfx@hackeriet
Channel / Frequency11 / 2462
Cell ID02:BA:00:00:00:01

+ +

The reason for setting ad-hoc wifi Cell ID is to work around bugs +in firmware used in wifi card and wifi drivers. (See a nice post from +VillageTelco about +"Information +about cell-id splitting, stuck beacons, and failed IBSS merges! +for details.) When these settings are activated and you have some +other mesh node nearby, your computer will be connected to the mesh +network and can communicate with any mesh node that is connected to +any of the nodes in your network of nodes. :)

+ +

My initial plan was to reuse my old Linksys WRT54GL as a mesh node, +but that seem to be very hard, as I have not been able to locate a +firmware supporting batman-adv. If anyone know how to use that old +wifi access point with batman-adv these days, please let me know.

+ +

If you find this project interesting and want to join, please join +us on IRC, either channel +#oslohackerspace +or #nuug on +irc.freenode.net.

+ +

While investigating mesh networks in Oslo, I came across an old +research paper from the university of Stavanger and Telenor Research +and Innovation called +The +reliability of wireless backhaul mesh networks and elsewhere +learned that Telenor have been experimenting with mesh networks at +Grünerløkka in Oslo. So mesh networks are also interesting for +commercial companies, even though Telenor discovered that it was hard +to figure out a good business plan for mesh networking and as far as I +know have closed down the experiment. Perhaps Telenor or others would +be interested in a cooperation?

+ +

Update 2013-10-12: I was just +told +by the Serval project developers that they no longer use +batman-adv (but are compatible with it), but their own crypto based +mesh system.

The Thinkpad is dead, long live the Thinkpad X230?
-
5th July 2013
-

Half a year ago, I reported that I had to find a -replacement -for my trusty old Thinkpad X41. Unfortunately I did not have much -time to spend on it, and it took a while to find a model I believe -will do the job, but two days ago the replacement finally arrived. I -ended up picking a -Thinkpad X230 -with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as -a roaming workstation, and it seemed to work flawlessly. But my -second installation with encrypted disk was not as successful. More -on that below.

- -

I had a hard time trying to track down a good laptop, as my most -important requirements (robust and with a good keyboard) are never -listed in the feature list. But I did get good help from the search -feature at Prisjakt, which -allowed me to limit the list of interesting laptops based on my other -requirements. A bit surprising that SSD disk are not disks according -to that search interface, so I had to drop specifying the number of -disks from my search parameters. I also asked around among friends to -get their impression on keyboards and robustness.

- -

So the new laptop arrived, and it is quite a lot wider than the -X41. I am not quite convinced about the keyboard, as it is -significantly wider than my old keyboard, and I have to stretch my -hand a lot more to reach the edges. But the key response is fairly -good and the individual key shape is fairly easy to handle, so I hope -I will get used to it. My old X40 was starting to fail, and I really -needed a new laptop now. :)

- -

Turning off the touch pad was simple. All it took was a quick -visit to the BIOS during boot it disable it.

- -

But there is a fatal problem with the laptop. The 180 GB SSD disk -lock up during load. And this happen when installing Debian Wheezy -with encrypted disk, while the disk is being filled with random data. -I also tested to install Ubuntu Raring, and it happen there too if I -reenable the code to fill the disk with random data (it is disabled by -default in Ubuntu). And the bug with is already known. It was -reported to Debian as BTS -report #691427 2012-10-25 (journal commit I/O error on brand-new -Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux -kernel developers as -Kernel bugzilla -report #51861 2012-12-20 (Intel SSD 520 stops working under load -(SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the -Lenovo forums, both for -T430 -2012-11-10 and for -X230 -03-20-2013. The problem do not only affect installation. The -reports state that the disk lock up during use if many writes are done -on the disk, so it is much no use to work around the installation -problem and end up with a computer that can lock up at any moment. -There is even a -small C program -available that will lock up the hard drive after running a few -minutes by writing to a file.

- -

I've contacted my supplier and asked how to handle this, and after -contacting PCHELP Norway (request 01D1FDP) which handle support -requests for Lenovo, his first suggestion was to upgrade the disk -firmware. Unfortunately there is no newer firmware available from -Lenovo, as my disk already have the most recent one (version LF1i). I -hope to hear more from him today and hope the problem can be -fixed. :)

Skolelinux / Debian Edu 7.1 install and overview video from Marcelo Salvador
+
8th October 2013

The other day I was pleased and surprised to discover that Marcelo +Salvador had published a +video on +Youtube showing how to install the standalone Debian Edu / +Skolelinux profile. This is the profile intended for use at home or +on laptops that should not be integrated into the provided network +services (no central home directory, no Kerberos / LDAP directory etc, +in other word a single user machine). The result is 11 minutes long, +and show some user applications (seem to be rather randomly picked). +Missed a few of my favorites like celestia, planets and chromium +showing the Zygote Body 3D model +of the human body, but I guess he did not know about those or find +other programs more interesting. :) And the video do not show the +advantages I believe is one of the most valuable featuers in Debian +Edu, its central school server making it possible to run hundreds of +computers without hard drives by installing one central +LTSP server.

Automatically locate and install required firmware packages on Debian (Isenkram 0.4)
-
25th June 2013
-

It annoys me when the computer fail to do automatically what it is -perfectly capable of, and I have to do it manually to get things -working. One such task is to find out what firmware packages are -needed to get the hardware on my computer working. Most often this -affect the wifi card, but some times it even affect the RAID -controller or the ethernet card. Today I pushed version 0.4 of the -Isenkram package -including a new script isenkram-autoinstall-firmware handling the -process of asking all the loaded kernel modules what firmware files -they want, find debian packages providing these files and install the -debian packages. Here is a test run on my laptop:

- -

-# isenkram-autoinstall-firmware 
-info: kernel drivers requested extra firmware: ipw2200-bss.fw ipw2200-ibss.fw ipw2200-sniffer.fw
-info: fetching http://http.debian.net/debian/dists/squeeze/Contents-i386.gz
-info: locating packages with the requested firmware files
-info: Updating APT sources after adding non-free APT source
-info: trying to install firmware-ipw2x00
-firmware-ipw2x00
-firmware-ipw2x00
-Preconfiguring packages ...
-Selecting previously deselected package firmware-ipw2x00.
-(Reading database ... 259727 files and directories currently installed.)

-Setting up firmware-ipw2x00 (0.28+squeeze1) ...
-# 
-

- -

When all the requested firmware is present, a simple message is -printed instead:

- -

-# isenkram-autoinstall-firmware 
-info: did not find any firmware files requested by loaded kernel modules.  exiting
-# 
-

- -

It could use some polish, but it is already working well and saving -me some time when setting up new machines. :)

- -

So, how does it work? It look at the set of currently loaded -kernel modules, and look up each one of them using modinfo, to find -the firmware files listed in the module meta-information. Next, it -download the Contents file from a nearby APT mirror, and search for -the firmware files in this file to locate the package with the -requested firmware file. If the package is in the non-free section, a -non-free APT source is added and the package is installed using -apt-get install. The end result is a slightly better working -machine.

- -

I hope someone find time to implement a more polished version of -this script as part of the hw-detect debian-installer module, to -finally fix BTS report -#655507. There really is no need to insert USB sticks with -firmware during a PXE install when the packages already are available -from the nearby Debian mirror.

About Debian Edu and Skolelinux

+ +

Debian Edu, also known as Skolelinux, is a Linux distribution based +on Debian providing an out-of-the box environment of a completely +configured school network. Immediately after installation a school +server running all services needed for a school network is set up just +waiting for users and machines being added via GOsa², a comfortable +Web-UI. A netbooting environment is prepared using PXE, so after +initial installation of the main server from CD or USB stick all other +machines can be installed via the network. The provided school server +provides LDAP database and Kerberos authentication service, +centralized home directories, DHCP server, web proxy and many other +services. The desktop contains more than 60 educational software +packages and more are available from the Debian archive, and schools +can choose between KDE, Gnome, LXDE and Xfce desktop environment.

+ +

This is the seventh test release based on Debian Wheezy. Basically +this is an updated and slightly improved version compared to the +Squeeze release.

+ +

Notes for upgrades from Alpha Prereleases

+ +

Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release. Both alpha and beta0 based installations should reinstall or +deal with gosa.conf manually; there are two options: (1) Keep +gosa.conf and edit this file as outlined on the mailing list. (2) +Accept the new version of gosa.conf and replace both contained admin +password placeholders with the password hashes found in the old one +(backup copy!). In both cases all users need to change their password +to make sure a password is set for CIFS access to their home +directory.

+ + +

cheers, +
Holger

The value of a good distro wide test suite...
-
22nd June 2013
-

In the Debian Edu / -Skolelinux project, we include a post-installation test suite, -which check that services are running, working, and return the -expected results. It runs automatically just after the first boot on -test installations (using test ISOs), but not on production -installations (using non-test ISOs). It test that the LDAP service is -operating, Kerberos is responding, DNS is replying, file systems are -online resizable, etc, etc. And it check that the PXE service is -configured, which is the topic of this post.

- -

The last week I've fixed the DVD and USB stick ISOs for our Debian -Edu Wheezy release. These ISOs are supposed to be able to install a -complete system without any Internet connection, but for that to -happen all the needed packages need to be on them. Thanks to our test -suite, I discovered that we had forgotten to adjust our PXE setup to -cope with the new names and paths used by the netboot d-i packages. -When Internet connectivity was available, the installer fall back to -using wget to fetch d-i boot images, but when offline it require -working packages to get it working. And ad the packages changed name -from debian-installer-6.0-netboot-$arch to -debian-installer-7.0-netboot-$arch, we no longer pulled in the -packages during installation. Without our test suite, I suspect we -would never have discovered this before release. Now it is fixed -right after we got the ISOs operational.

- -

Another by-product of the test suite is that we can ask system -administrators with problems getting Debian Edu to work, to run the -test suite using /usr/sbin/debian-edu-test-install and see if -any errors are detected. This usually pinpoint the subsystem causing -the problem.

Recipe to test the Freedombox project on amd64 or Raspberry Pi
+
10th September 2013
+

I was introduced to the +Freedombox project +in 2010, when Eben Moglen presented his vision about serving the need +of non-technical people to keep their personal information private and +within the legal protection of their own homes. The idea is to give +people back the power over their network and machines, and return +Internet back to its intended peer-to-peer architecture. Instead of +depending on a central service, the Freedombox will give everyone +control over their own basic infrastructure.

+ +

I've intended to join the effort since then, but other tasks have +taken priority. But this summers nasty news about the misuse of trust +and privilege exercised by the "western" intelligence gathering +communities increased my eagerness to contribute to a point where I +actually started working on the project a while back.

+ +

The initial +Debian initiative based on the vision from Eben Moglen, is to +create a simple and cheap Debian based appliance that anyone can hook +up in their home and get access to secure and private services and +communication. The initial deployment platform have been the +Dreamplug, +which is a piece of hardware I do not own. So to be able to test what +the current Freedombox setup look like, I had to come up with a way to install +it on some hardware I do have access to. I have rewritten the +freedom-maker +image build framework to use .deb packages instead of only copying +setup into the boot images, and thanks to this rewrite I am able to +set up any machine supported by Debian Wheezy as a Freedombox, using +the previously mentioned deb (and a few support debs for packages +missing in Debian).

+ +

The current Freedombox setup consist of a set of bootstrapping +scripts +(freedombox-setup), +and a administrative web interface +(plinth + exmachina + +withsqlite), as well as a privacy enhancing proxy based on +privoxy +(freedombox-privoxy). There is also a web/javascript based XMPP +client (jwchat) +trying (unsuccessfully so far) to talk to the XMPP server +(ejabberd). The +web interface is pluggable, and the goal is to use it to enable OpenID +services, mesh network connectivity, use of TOR, etc, etc. Not much of +this is really working yet, see +the +project TODO for links to GIT repositories. Most of the code is +on github at the moment. The HTTP proxy is operational out of the +box, and the admin web interface can be used to add/remove plinth +users. I've not been able to do anything else with it so far, but +know there are several branches spread around github and other places +with lots of half baked features.

+ +

Anyway, if you want to have a look at the current state, the +following recipes should work to give you a test machine to poke +at.

+ +

Debian Wheezy amd64

+ +
    + +
  1. Fetch normal Debian Wheezy installation ISO.
    2. +
  2. Boot from it, either as CD or USB stick.
    3. +

  3. Press [tab] on the boot prompt and add this as a boot argument +to the Debian installer:

    +

    url=http://www.reinholdtsen.name/freedombox/preseed-wheezy.dat
    4. + +
  4. Answer the few language/region/password questions and pick disk to +install on.
    5. + +
  5. When the installation is finished and the machine have rebooted a +few times, your Freedombox is ready for testing.
    6. + +
+ +

Raspberry Pi Raspbian

+ +
    + +
  1. Fetch a Raspbian SD card image, create SD card.
    2. +
  2. Boot from SD card, extend file system to fill the card completely.
    3. +

  3. Log in and add this to /etc/sources.list:

    +
    +deb http://www.reinholdtsen.name/freedombox wheezy main
+
    4. +

  4. Run this as root:

    +
    +wget -O - http://www.reinholdtsen.name/freedombox/BE1A583D.asc | \
+   apt-key add -
+apt-get update
+apt-get install freedombox-setup
+/usr/lib/freedombox/setup
+
    5. +
  5. Reboot into your freshly created Freedombox.
    6. + +
+ +

You can test it on other architectures too, but because the +freedombox-privoxy package is binary, it will only work as intended on +the architectures where I have had time to build the binary and put it +in my APT repository. But do not let this stop you. It is only a +short "apt-get source -b freedombox-privoxy" away. :)

+ +

Note that by default Freedombox is a DHCP server on the +192.168.1.0/24 subnet, so if this is your subnet be careful and turn +off the DHCP server by running "update-rc.d isc-dhcp-server +disable" as root.

+ +

Please let me know if this works for you, or if you have any +problems. We gather on the IRC channel +#freedombox on +irc.debian.org and the +project +mailing list.

+ +

Once you get your freedombox operational, you can visit +http://your-host-name:8001/ to see the state of the plint +welcome screen (dead end - do not be surprised if you are unable to +get past it), and next visit http://your-host-name:8001/help/ +to look at the rest of plinth. The default user is 'admin' and the +default password is 'secret'.

Debian Edu interview: Victor Nițu
-
17th June 2013
-

The Debian Edu and -Skolelinux distribution have users and contributors all around the -globe. And a while back, an enterprising young man showed up on -our IRC channel -#debian-edu and started asking questions about how Debian Edu -worked. We answered as good as we could, and even convinced him to -help us with translations. And today I managed to get an interview -with him, to learn more about him.

- -

Who are you, and how do you spend your days?

- -

I'm a 25 year old free software enthusiast, living in Romania, -which is also my country of origin. Back in 2009, at a New Year's Eve -party, I had a very nice beer discussion with a -friend, when we realized we have no organised Debian community in our -country. A few days later, we put together the infrastructure for such -community and even gathered a nice Debian-ish crowd. Since then, I -began my quest as a free software hacker and activist and I am -constantly trying to cover as much ground as possible on that -field.

- -

A few years ago I founded a small web development company, which -provided me the flexible schedule I needed so much for my -activities. For the last 13 months, I have been the Technical Director -of Fundația Ceata, which is a free -software activist organisation endorsed by the FSF and the FSFE, and -the only one we have in our country.

- -

How did you get in contact with the Skolelinux / Debian Edu -project?

- -

The idea of participating in the Debian Edu project was a surprise -even to me, since I never used it before I began getting involved in -it. This year I had a great opportunity to deliver a talk on -educational software, and I knew immediately where to look. It was a -love at first sight, since I was previously involved with some of the -technologies the project incorporates, and I rapidly found a lot of -ways to contribute.

- -

My first contributions consisted in translating the installer and -configuration dialogs, then I found some bugs to squash (I still -haven't fixed them yet though), and I even got my eyes on some other -areas where I can prove myself helpful. Since the appetite for free -software in my country is pretty low, I'll be happy to be the first -one around here advocating for the project's adoption in educational -environments, and maybe even get my hands dirty in creating a flavour -for our own needs. I am not used to make very advanced plannings, so -from now on, time will tell what I'll be doing next, but I think I -have a pretty consistent starting point.

- -

What do you see as the advantages of Skolelinux/Debian -Edu?

- -

Not a long time ago, I was in the position of configuring and -maintaining a LDAP server on some Debian derivative, and I must say it -took me a while. A long time ago, I was maintaining a bigger -Samba-powered infrastructure, and I must say I spent quite a lot of -time on it. I have similar stories about many of the services included -with Skolelinux, and the main advantage I see about it is the -out-of-the box availability of them, making it quite competitive when -it comes to managing a school's network, for example.

- -

Of course, there is more to say about Skolelinux than the -availability of the software included, its flexibility in various -scenarios is something I can't wait to experiment "into the wild" (I -only played with virtual machines so far). And I am sure there is a -lot more I haven't discovered yet about it, being so new within the -project.

- -

What do you see as the disadvantages of Skolelinux / Debian -Edu?

- -

As usual, when it comes to Debian Blends, I see as the biggest -disadvantage the lack of a numerous team dedicated to the -project. Every day I see the same names in the changelogs, and I have -a constantly fear of the bus factor in this story. I'd like to see -Debian Edu advertised more as an entry point into the Debian -ecosystem, especially amongst newcomers and students. IMHO there are a -lot low-hanging fruits in terms of bug squashing, and enough -opportunities to get the feeling of the Debian Project's dynamics. Not -to mention it's a very fun blend to work on!

- -

Derived from the previous statement, is the delay in catching up -with the main Debian release and documentation. This is common though -to all blends and derivatives, but it's an issue we can all work -on.

- -

Which free software do you use daily?

- -

I can hardly imagine myself spending a day without Vim, since my -daily routine covers writing code and hacking configuration files. I -am a fan of the Awesome window manager (but I also like the -Enlightenment project a lot!), -Claws Mail due to its ease of -use and very configurable behaviour. Recently I fell in love with -Redshift, which helps me -get through the night without headaches. Of course, there is much more -stuff in this bag, but I'll need a blog on my own for doing this!

- -

Which strategy do you believe is the right one to use to -get schools to use free software?

- -

Well, on this field, I cannot do much more than experiment right -now. So, being far from having a recipe for success, I can only assume -that:

Datalagringsdirektivet gjør at Oslo Høyre og Arbeiderparti ikke får min stemme i år
+
8th September 2013
+

I 2011 raderte et stortingsflertall bestående av Høyre og +Arbeiderpartiet vekk en betydelig del av privatsfæren til det norske +folk. Det ble vedtatt at det skulle registreres og lagres i et halvt +år hvor alle som bærer på en mobiltelefon befinner seg, hvem de +snakker med og hvor lenge de snakket sammen. Det skal også +registreres hvem de sendte SMS-meldinger til, hvem en har sendt epost +til, og hvilke nett-tjenere en besøkte. Saken er kjent som +Datalagringsdirektivet +(DLD), og innebærer at alle innbyggerne og andre innenfor Norges +grenser overvåkes døgnet rundt. Det ble i praksis innført brev og +besøkskontroll av hele befolkningen. Rapporter fra de landene som +allerede har innført slik total lagring av borgernes +kommunikasjonsmønstre forteller at det ikke hjelper i +kriminalitetsbekjempelsen. Den norske prislappen blir mange hundre +millioner, uten at det ser ut til å bidra positivt til politiets +arbeide. Jeg synes flere hundre millioner i stedet burde vært brukt +på noe som kan dokumenteres å ha effekt i kriminalitetsbekjempelsen. +Se mer på +Wikipedia +og Jon Wessel-Aas.

+ +

Hva er problemet, tenkter du kanskje? Et åpenbart problem er at +medienes kildevern i praksis blir radert ut. Den innsamlede +informasjonen gjør det mulig å finne ut hvem som har snakket med +journalister på telefon, SMS og epost, og hvem som har vært i nærheten +av journalister så sant begge bar med seg en telefon. Et annet er at +advokatvernet blir sterkt redusert, der politiet kan finne ut hvem +som har snakket med en advokat når, eller vært i møter en med advokat. +Et tredje er at svært personlig informasjon kan avledes fra hvilke +nettsteder en har besøkt. Har en besøkt hivnorge.no, +swingersnorge.com eller andre sider som kan brukes til avlede +interesser som hører til privatsfæren, vil denne informasjonen være +tilgjengelig takket være datalagringsdirektivet.

+ +

De fleste partiene var mot, kun to partier stemte for. Høyre og +Arbeiderpartiet. Og både Høyre og Arbeiderpartiet i Oslo har +DLD-forkjempere på toppen av sine lister (har ikke sjekket de andre +fylkene). Det er dermed helt uaktuelt for meg å stemme på disse +partiene. Her er oversikten over partienes valglister i Oslo, med +informasjon om hvem som stemte hva i første DLD-votering i Stortinget, +basert på informasjon fra mine venner i +Holder de +Ord samt data.stortinget.no. +Først ut er stortingslista fra Høyre for Oslo:

  • schools would like to get rid of proprietary software
    • + + + -
  • students will love the openness of the system, and will want to - experiment with it - maybe we need to harvest the native curiosity - of teenagers more?
    • + + + -
  • there is no "right one" when it comes to strategies, but it would - be useful to have some success stories published somewhere, so - other can get some inspiration from them (I know I'd promote - them!)

    Debian Edu interview: Jonathan Carter
    -
    12th June 2013
    -

    There is a certain cross-over between the -Debian Edu / Skolelinux -project and the Edubuntu -project, and for example the LTSP packages in Debian are a joint -effort between the projects. One person with a foot in both camps is -Jonathan Carter, which I am now happy to present to you.

    - -

    Who are you, and how do you spend your days?

    - -

    I'm a South-African free software geek who lives in Cape Town. My -days vary quite a bit since I'm involved in too many things. As I'm -getting older I'm learning how to focus a bit more :)

    - -

    I'm also an Edubuntu contributor and I love when there are -opportunities for the Edubuntu and Debian Edu projects to benefit from -each other.

    - -

    How did you get in contact with the Skolelinux / Debian Edu -project?

    - -

    I've been somewhat familiar with the project before, but I think my -first direct exposure to the project was when I met Petter -[Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in 2005 in -London. They provided great feedback that helped the bootstrapping of -Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and -it was great getting input from people who have been around longer. I -was also still very excitable and said yes to everything and to this -day I have a big todo list backlog that I'm catching up with. I think -over the years the relationship between Edubuntu and Debian-Edu has -been gradually improving, although I think there's a lot that we could -still improve on in terms of working together on packages. I'm sure -we'll get there one day.

    - -

    What do you see as the advantages of Skolelinux / Debian -Edu?

    - -

    Debian itself already has so many advantages. I could go on about -it for pages, but in essence I love that it's a very honest project -that puts its users first with no hidden agendas and also produces -very high quality work.

    - -

    I think the advantage of Debian Edu is that it makes many common -set-up tasks simpler so that administrators can get up and running -with a lot less effort and frustration. At the same time I think it -helps to standardise installations in schools so that it's easier for -community members and commercial suppliers to support.

    - -

    What do you see as the disadvantages of Skolelinux / Debian -Edu?

    - -

    I had to re-type this one a few times because I'm trying to -separate "disadvantages" from "areas that need improvement" (which is -what I originally rambled on about)

    - -

    The biggest disadvantage I can think of is lack of manpower. The -project could do so much more if there were more good contributors. I -think some of the problems are external too. Free software and free -content in education is a no-brainer but it takes some time to catch -on. When you've been working with the same proprietary eco-system for -years and have gotten used to it, it can be hard to adjust to some -concepts in the free software world. It would be nice if there were -more Debian Edu consultants across the world. I'd love to be one -myself but I'm already so over-committed that it's just not possible -currently.

    - -

    I think the best short-term solution to that large-scale problem is -for schools to be pro-active and share their experiences and grow -their skills in-house. I'm often saddened to see how much money -educational institutions spend on 3rd party solutions that they don't -have access to after the service has ended and they could've gotten so -much more value otherwise by being more self-sustainable and -autonomous.

    - -

    Which free software do you use daily?

    - -

    My main laptop dual-boots between Debian and Windows 7. I was -Windows free for years but started dual-booting again last year for -some games which help me focus and relax (Starcraft II in -particular). Gaming support on Linux is improving in leaps and bounds -so I suppose I'll soon be able to regain that disk space :)

    - -

    Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi, -git, Tomboy, KVM, VLC and LibreOffice. Recently I've been torn on -which desktop environment I like and I'm taking some refuge in Xfce -while I figure that out. I like tools that keep things simple. I enjoy -Python and shell scripting. I went to an Arduino workshop recently and -it was awesome seeing how easy and simple the IDE software was to get -up and running in Debian compared to the users running Windows and OS -X.

    - -

    I also use mc which some people frown upon slightly. I got used to -using Norton Commander in the early 90's and it stuck (I think the -people who sneer at it is just jealous that they don't know how to use -it :p) - -

    Which strategy do you believe is the right one to use to -get schools to use free software?

    - -

    I think trying to force it is unproductive. I also think that in -many cases it's appropriate for schools to use non-free systems and I -don't think that there's any particular moral or ethical problem with -that.

    - -

    I do think though that free software can already solve so so many -problems in educational institutions and it's just a shame not taking -advantage of that.

    - -

    I also think that some curricula need serious review. For example, -some areas of the world rely heavily on very specific versions of MS -Office, teaching students to parrot menu items instead of learning the -general concepts. I think that's very unproductive because firstly, MS -Office's interface changes drastically every few years and on top of -that it also locks in a generation to a product that might not be the -best solution for them.

    - -

    To answer your question, I believe that the right strategy is to -educate and inform, giving someone the information they require to -make a decision that would work for them.

    Second beta release (beta 1) of Debian Edu/Skolelinux based on Debian Wheezy
    +
    22nd August 2013
    +

    The second wheezy based beta release of Debian Edu was wrapped up +today, slightly delayed because of some bugs in the initial Windows +integration fixes . This is the release announcement:

    + +

    New features for Debian Edu 7.1+edu0~b1 released 2013-08-22

    + +

    These are the release notes for Debian Edu / Skolelinux +7.1+edu0~b1, based on Debian with codename "Wheezy".

    + +

    About Debian Edu and Skolelinux

    + +

    Debian Edu, also known as +Skolelinux, is a Linux distribution based on Debian providing an +out-of-the box environment of a completely configured school +network. Immediately after installation a school server running all +services needed for a school network is set up just waiting for users +and machines being added via GOsa², a comfortable Web-UI. A netbooting +environment is prepared using PXE, so after initial installation of +the main server from CD or USB stick all other machines can be +installed via the network. The provided school server provides LDAP +database and Kerberos authentication service, centralized home +directories, DHCP server, web proxy and many other services. The +desktop contains +more +than 60 educational software packages and more are available from +the Debian archive, and schools can choose between KDE, Gnome, LXDE +and Xfce desktop environment.

    + +

    This is the sixth test release based on Debian Wheezy. Basically this +is an updated and slightly improved version compared to the Squeeze +release.

    + +

    ALERT: Alpha based installations should reinstall or downgrade the +versions of gosa and libpam-mklocaluser to the ones used in this beta +release. Both alpha and beta0 based installations should reinstall or +deal with gosa.conf manually; there are two options: (1) Keep +gosa.conf and edit this file as outlined +on +the mailing list. (2) Accept the new version of gosa.conf and +replace both contained admin password placeholders with the password +hashes found in the old one (backup copy!). In both cases every user +need to change their their password to make sure a password is set for +CIFS access to their home directory.

    + +

    Software updates

    + +
      + +
    • Added ssh askpass packages to default installation, to ensure ssh + work also without a attached tty.
      • +
    • Add the command-not-found package to the default installation to + make it easier to figure out where to find missing command line + tools. Please note, that the command 'update-command-not-found' + has to be run as root to actually make it useful (internet access + required).
      • + +
    + +

    Other changes

    + +
      + +
    • Adjusted the USB stick ISO image build to include every tool +needed for desktop=xfce installations.
      • +
    • Adjust thin-client-server task to work when installing from USB +stick ISO image.
      • +
    • Made new grub artwork (changed png from indexed to RGB format).
      • +
    • Minor cleanup in the CUPS setup.
      • +
    • Make sure that bootstrapping of the Samba domain really happens + during installation of the main server and adjust SID handling to + cope with this.
      • +
    • Make Samba passwords changeable (again) via GOsa².
      • +
    • Fix generation of LM and NT password hashes via GOsa² to avoid + empty password hashes.
      • +
    • Adapted Samba machine domain joining to latest change in the + smbldap-tools Perl package, fixing bugs blocking Windows machines + from joining the Samba domain.
      • + +
    + +

    Known issues

    + +
      + +
    • KDE fails to understand the wpad.dat file provided, causing it to + not use the http proxy as it should.
      • +
    • Chromium also fails to use the proxy when using the KDE desktop + (using the KDE configuration).

    Fixing the Linux black screen of death on machines with Intel HD video
    -
    11th June 2013
    -

    When installing RedHat, Fedora, Debian and Ubuntu on some machines, -the screen just turn black when Linux boot, either during installation -or on first boot from the hard disk. I've seen it once in a while the -last few years, but only recently understood the cause. I've seen it -on HP laptops, and on my latest acquaintance the Packard Bell laptop. -The reason seem to be in the wiring of some laptops. The system to -control the screen background light is inverted, so when Linux try to -turn the brightness fully on, it end up turning it off instead. I do -not know which Linux drivers are affected, but this post is about the -i915 driver used by the -Packard Bell -EasyNote LV, Thinkpad X40 and many other laptops.

    - -

    The problem can be worked around two ways. Either by adding -i915.invert_brightness=1 as a kernel option, or by adding a file in -/etc/modprobe.d/ to tell modprobe to add the invert_brightness=1 -option when it load the i915 kernel module. On Debian and Ubuntu, it -can be done by running these commands as root:

    - -
    -echo options i915 invert_brightness=1 | tee /etc/modprobe.d/i915.conf
-update-initramfs -u -k all
-
    - -

    Since March 2012 there is -a -mechanism in the Linux kernel to tell the i915 driver which -hardware have this problem, and get the driver to invert the -brightness setting automatically. To use it, one need to add a row in -the -intel_quirks array in the driver source -drivers/gpu/drm/i915/intel_display.c (look for "static -struct intel_quirk intel_quirks"), specifying the PCI device -number (vendor number 8086 is assumed) and subdevice vendor and device -number.

    - -

    My Packard Bell EasyNote LV got this output from lspci --vvnn for the video card in question:

    - -

-    3rd Gen Core processor Graphics Controller [8086:0156] \

- Subsystem: Acer Incorporated [ALI] Device [1025:0688]

-    SERR-  [disabled]
- Capabilities: 
- Kernel driver in use: i915
-

    - -

    The resulting intel_quirks entry would then look like this:

    - -

    -struct intel_quirk intel_quirks[] = {
-       ...
-        /* Packard Bell EasyNote LV11HC needs invert brightness quirk */
-	{ 0x0156, 0x1025, 0x0688, quirk_invert_brightness },
-       ...
-}
-

    - -

    According to the kernel module instructions (as seen using -modinfo i915), information about hardware needing the -invert_brightness flag should be sent to the -dri-devel -(at) lists.freedesktop.org mailing list to reach the kernel -developers. But my email about the laptop sent 2013-06-03 have not -yet shown up in -the -web archive for the mailing list, so I suspect they do not accept -emails from non-subscribers. Because of this, I sent my patch also to -the Debian bug tracking system instead as -BTS report #710938, to make -sure the patch is not lost.

    - -

    Unfortunately, it is not enough to fix the kernel to get Laptops -with this problem working properly with Linux. If you use Gnome, your -worries should be over at this point. But if you use KDE, there is -something in KDE ignoring the invert_brightness setting and turning on -the screen during login. I've reported it to Debian as -BTS report #711237, and -have no idea yet how to figure out exactly what subsystem is doing -this. Perhaps you can help? Perhaps you know what the Gnome -developers did to handle this, and this can give a clue to the KDE -developers? Or you know where in KDE the screen brightness is changed -during login? If so, please update the BTS report (or get in touch if -you do not know how to update BTS).

    Intel 180 SSD disk with Lenovo firmware can not use Intel firmware
    +
    18th August 2013
    +

    Earlier, I reported about +my +problems using an Intel SSD 520 Series 180 GB disk. Friday I was +told by IBM that the original disk should be thrown away. And as +there no longer was a problem if I bricked the firmware, I decided +today to try to install Intel firmware to replace the Lenovo firmware +currently on the disk.

    + +

    I searched the Intel site for firmware, and found +issdfut_2.0.4.iso +(aka Intel SATA Solid-State Drive Firmware Update Tool) which +according to the site should contain the latest firmware for SSD +disks. I inserted the broken disk in one of my spare laptops and +booted the ISO from a USB stick. The disk was recognized, but the +program claimed the newest firmware already were installed and refused +to insert any Intel firmware. So no change, and the disk is still +unable to handle write load. :( I guess the only way to get them +working would be if Lenovo releases new firmware. No idea how likely +that is. Anyway, just blogging about this test for completeness. I +got a working Samsung disk, and see no point in spending more time on +the broken disks.
