Debian Jessie, PXE and automatic firmware installation
-
17th October 2014
-

When PXE installing laptops with Debian, I often run into the -problem that the WiFi card require some firmware to work properly. -And it has been a pain to fix this using preseeding in Debian. -Normally something more is needed. But thanks to -my isenkram -package and its recent tasksel extension, it has now become easy -to do this using simple preseeding.

- -

The isenkram-cli package provide tasksel tasks which will install -firmware for the hardware found in the machine (actually, requested by -the kernel modules for the hardware). (It can also install user space -programs supporting the hardware detected, but that is not the focus -of this story.)

- -

To get this working in the default installation, two preeseding -values are needed. First, the isenkram-cli package must be installed -into the target chroot (aka the hard drive) before tasksel is executed -in the pkgsel step of the debian-installer system. This is done by -preseeding the base-installer/includes debconf value to include the -isenkram-cli package. The package name is next passed to debootstrap -for installation. With the isenkram-cli package in place, tasksel -will automatically use the isenkram tasks to detect hardware specific -packages for the machine being installed and install them, because -isenkram-cli contain tasksel tasks.

- -

Second, one need to enable the non-free APT repository, because -most firmware unfortunately is non-free. This is done by preseeding -the apt-mirror-setup step. This is unfortunate, but for a lot of -hardware it is the only option in Debian.

- -

The end result is two lines needed in your preseeding file to get -firmware installed automatically by the installer:

- -

-base-installer base-installer/includes string isenkram-cli
-apt-mirror-setup apt-setup/non-free boolean true
-

- -

The current version of isenkram-cli in testing/jessie will install -both firmware and user space packages when using this method. It also -do not work well, so use version 0.15 or later. Installing both -firmware and user space packages might give you a bit more than you -want, so I decided to split the tasksel task in two, one for firmware -and one for user space programs. The firmware task is enabled by -default, while the one for user space programs is not. This split is -implemented in the package currently in unstable.

- -

If you decide to give this a go, please let me know (via email) how -this recipe work for you. :)

- -

So, I bet you are wondering, how can this work. First and -foremost, it work because tasksel is modular, and driven by whatever -files it find in /usr/lib/tasksel/ and /usr/share/tasksel/. So the -isenkram-cli package place two files for tasksel to find. First there -is the task description file (/usr/share/tasksel/descs/isenkram.desc):

- -

-Task: isenkram-packages
-Section: hardware
-Description: Hardware specific packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific packages are
- proposed.
-Test-new-install: show show
-Relevance: 8
-Packages: for-current-hardware
-
-Task: isenkram-firmware
-Section: hardware
-Description: Hardware specific firmware packages (autodetected by isenkram)
- Based on the detected hardware various hardware specific firmware
- packages are proposed.
-Test-new-install: mark show
-Relevance: 8
-Packages: for-current-hardware-firmware
-

- -

The key parts are Test-new-install which indicate how the task -should be handled and the Packages line referencing to a script in -/usr/lib/tasksel/packages/. The scripts use other scripts to get a -list of packages to install. The for-current-hardware-firmware script -look like this to list relevant firmware for the machine: - -

-#!/bin/sh
-#
-PATH=/usr/sbin:$PATH
-export PATH
-isenkram-autoinstall-firmware -l
-

- -

With those two pieces in place, the firmware is installed by -tasksel during the normal d-i run. :)

- -

If you want to test what tasksel will install when isenkram-cli is -installed, run DEBIAN_PRIORITY=critical tasksel --test ---new-install to get the list of packages that tasksel would -install.

- -

Debian Edu will be -pilots in testing this feature, as isenkram is used there now to -install firmware, replacing the earlier scripts.

9th August 2017

On friday, I came across an interesting article in the Norwegian +web based ICT news magazine digi.no on +how +to collect the IMSI numbers of nearby cell phones using the cheap +DVB-T software defined radios. The article refered to instructions +and a recipe by +Keld Norman on Youtube on how to make a simple $7 IMSI Catcher, and I decided to test them out.

+ +

The instructions said to use Ubuntu, install pip using apt (to +bypass apt), use pip to install pybombs (to bypass both apt and pip), +and the ask pybombs to fetch and build everything you need from +scratch. I wanted to see if I could do the same on the most recent +Debian packages, but this did not work because pybombs tried to build +stuff that no longer build with the most recent openssl library or +some other version skew problem. While trying to get this recipe +working, I learned that the apt->pip->pybombs route was a long detour, +and the only piece of software dependency missing in Debian was the +gr-gsm package. I also found out that the lead upstream developer of +gr-gsm (the name stand for GNU Radio GSM) project already had a set of +Debian packages provided in an Ubuntu PPA repository. All I needed to +do was to dget the Debian source package and built it.

+ +

The IMSI collector is a python script listening for packages on the +loopback network device and printing to the terminal some specific GSM +packages with IMSI numbers in them. The code is fairly short and easy +to understand. The reason this work is because gr-gsm include a tool +to read GSM data from a software defined radio like a DVB-T USB stick +and other software defined radios, decode them and inject them into a +network device on your Linux machine (using the loopback device by +default). This proved to work just fine, and I've been testing the +collector for a few days now.

+ +

The updated and simpler recipe is thus to

+ +
    + +
  1. start with a Debian machine running Stretch or newer,
  2. + +
  3. build and install the gr-gsm package available from +http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/,
  4. + +
  5. clone the git repostory from https://github.com/Oros42/IMSI-catcher,
  6. + +
  7. run grgsm_livemon and adjust the frequency until the terminal +where it was started is filled with a stream of text (meaning you +found a GSM station).
  8. + +
  9. go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.
  10. + +
+ +

To make it even easier in the future to get this sniffer up and +running, I decided to package +the gr-gsm project +for Debian (WNPP +#871055), and the package was uploaded into the NEW queue today. +Luckily the gnuradio maintainer has promised to help me, as I do not +know much about gnuradio stuff yet.

+ +

I doubt this "IMSI cacher" is anywhere near as powerfull as +commercial tools like +The +Spy Phone Portable IMSI / IMEI Catcher or the +Harris +Stingray, but I hope the existance of cheap alternatives can make +more people realise how their whereabouts when carrying a cell phone +is easily tracked. Seeing the data flow on the screen, realizing that +I live close to a police station and knowing that the police is also +wearing cell phones, I wonder how hard it would be for criminals to +track the position of the police officers to discover when there are +police near by, or for foreign military forces to track the location +of the Norwegian military forces, or for anyone to track the location +of government officials...

+ +

It is worth noting that the data reported by the IMSI-catcher +script mentioned above is only a fraction of the data broadcasted on +the GSM network. It will only collect one frequency at the time, +while a typical phone will be using several frequencies, and not all +phones will be using the frequencies tracked by the grgsm_livemod +program. Also, there is a lot of radio chatter being ignored by the +simple_IMSI-catcher script, which would be collected by extending the +parser code. I wonder if gr-gsm can be set up to listen to more than +one frequency?

    Jeg kom over teksten +«Killing +car privacy by federal mandate» av Leonid Reyzin på Freedom to +Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det +er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin +posisjon og bevegelse via radio. Det omtalte forslaget basert på +Dedicated Short Range Communication (DSRC) kalles Basic Safety Message +(BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det +norske Vegvesenet er en av de som ser ut til å kunne tenke seg å +pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære. +Anbefaler alle å lese det som står der. + +

    Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat +jeg synes er illustrativt for hvordan det offentlige Norge håndterer +problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten +«Informasjonssikkerhet +i AutoPASS-brikker» av Trond Foss:

    -
  • Ignore 'phantom' audio, subtitle tracks
  • -
  • Check for garbage in the program chains, which indicate that a track is - non-existant, to work around additional copy protection
  • -
  • Fix displaying content type for audio tracks, subtitles
  • -
  • Fix pallete display of first entry
  • -
  • Fix include orders
  • -
  • Ignore read errors in titles that would not be displayed anyway
  • -
  • Fix the chapter count
  • -
  • Make sure the array size and the array limit used when initialising - the palette size is the same.
  • -
  • Fix array printing.
  • -
  • Correct subsecond calculations.
  • -
  • Add sector information to the output format.
  • -
  • Clean up code to be closer to ANSI C and compile without warnings - with more GCC compiler warnings.
  • - -

+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig + integritet.» +

-

This change bring together patches for lsdvd in use in various -Linux and Unix distributions, as well as patches submitted to the -project the last nine years. Please check it out. :)

+

Så enkelt kan det tydeligvis gjøres når en vurderer +informasjonssikkerheten. Det holder vel at folkene på toppen kan si +at «Personvernet er ivaretatt», som jo er den populære intetsigende +frasen som gjør at mange tror enkeltindividers integritet tas vare på. +Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se +bort fra behovet for personlig itegritet, blir valgt når en velger å +legge til rette for nok et inngrep i privatsfæren til personer i +Norge. Det er jo sjelden det får reaksjoner. Historien om +reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et +unntak og toppen av isfjellet, desverre. Tror jeg fortsatt takker nei +til både AutoPASS og holder meg så langt unna det norske helsevesenet +som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter +individets privatsfære og personlige integritet høyere enn kortsiktig +gevist og samfunnsnytte.

The Debian Edu / Skolelinux -project provide a Linux solution for schools, including a -powerful desktop with education software, a central server providing -web pages, user database, user home directories, central login and PXE -boot of both clients without disk and the installation to install Debian -Edu on machines with disk (and a few other services perhaps to small -to mention here). We in the Debian Edu team are currently working on -the Jessie based version, trying to get everything in shape before the -freeze, to avoid having to maintain our own package repository in the -future. The -current -status can be seen on the Debian wiki, and there is still heaps of -work left. Some fatal problems block testing, breaking the installer, -but it is possible to work around these to get anyway. Here is a -recipe on how to get the installation limping along.

- -

First, download the test ISO via -ftp, -http -or rsync (use -ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso). -The ISO build was broken on Tuesday, so we do not get a new ISO every -12 hours or so, but thankfully the ISO we already got we are able to -install with some tweaking.

It is pleasing to see that the work we put down in publishing new +editions of the classic Free +Culture book by the founder of the Creative Commons movement, +Lawrence Lessig, is still being appreciated. I had a look at the +latest sales numbers for the paper edition today. Not too impressive, +but happy to see some buyers still exist. All the revenue from the +books is sent to the Creative +Commons Corporation, and they receive the largest cut if you buy +directly from Lulu. Most books are sold via Amazon, with Ingram +second and only a small fraction directly from Lulu. The ebook +edition is available for free from +Github.

+ + + + + + -

and add 'exit 0' as the second line, disabling the eatmydata -optimization. Return to the installation, select the profile you want -and continue. Without this change, exim4-config will fail to install -due to a known bug in eatmydata.

- -

When you get the grub question at the end, answer /dev/sda (or if -this do not work, figure out what your correct value would be. All my -test machines need /dev/sda, so I have no advice if it do not fit -your need.

- -

If you installed a profile including a graphical desktop, log in as -root after the initial boot from hard drive, and install the -education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce -or mate. If you want several desktop options, install more than one -metapackage. Once this is done, reboot and you should have a working -graphical login screen. This workaround should no longer be needed -once the education-tasks package version 1.801 enter testing in two -days.

- -

I believe the ISO build will start working on two days when the new -tasksel package enter testing and Steve McIntyre get a chance to -update the debian-cd git repository. The eatmydata, grub and desktop -issues are already fixed in unstable and testing, and should show up -on the ISO as soon as the ISO build start working again. Well the -eatmydata optimization is really just disabled. The proper fix -require an upload by the eatmydata maintainer applying the patch -provided in bug #702711. -The rest have proper fixes in unstable.

- -

I hope this get you going with the installation testing, as we are -quickly running out of time trying to get our Jessie based -installation ready before the distribution freeze in a month.

It is a nice command line -tool to get details about a DVD, like title, tracks, track length, -etc, in XML, Perl or human readable format. But lsdvd have not seen -any new development since 2006 and had a few irritating bugs affecting -its use with some DVDs.

Av disse ser ID 775 og 862 mest relevant ut. ID 775 antar jeg -refererer til fotoboksen som står like ved brua, mens -«Reisetidsregistreringspunkt» kanskje kan være boksen som henger der. -Hvordan finner jeg så ut hva dette kan være for noe. En titt på -datakatalogsiden -for ID 862/Reisetidsregistreringspunkt viser at det er finnes 53 -slike målere i Norge, og hvor de er plassert, men gir ellers få -detaljer. Det er plassert 40 på østlandet og 13 i Trondheimsregionen. -Men siden nevner «AutoPASS», og hvis en slår opp oppføringen på -Sollihøgda nevner den «Ciber AS» som ID for eksternt system. (Kan det -være snakk om -Ciber -Norge AS, et selskap eid av Ciber Europe Bv?) Et nettsøk på - «Ciber AS autopass» fører meg til en artikkel fra NRK Trøndelag i - 2013 med tittel -«Sjekk -dette hvis du vil unngå kø». Artikkelen henviser til vegvesenets -nettside -reisetider.no -som har en -kartside -for Østlandet som viser at det måles mellom Sandvika og Sollihøgda. -Det kan dermed se ut til at jeg har funnet ut hva boksene gjør.

- -

Hvis det stemmer, så er dette bokser som leser av AutoPASS-ID-en -til alle passerende biler med AutoPASS-brikke, og dermed gjør det mulig -for de som kontrollerer boksene å holde rede på hvor en gitt bil er -når den passerte et slikt målepunkt. NRK-artikkelen forteller at -denne informasjonen i dag kun brukes til å koble to -AutoPASS-brikkepasseringer passeringer sammen for å beregne -reisetiden, og at bruken er godkjent av Datatilsynet. Det er desverre -ikke mulig for en sjåfør som passerer under en slik boks å kontrollere -at AutoPASS-ID-en kun brukes til dette i dag og i fremtiden.

I tillegg til denne type AutoPASS-sniffere vet jeg at det også -finnes mange automatiske stasjoner som tar betalt pr. passering (aka -bomstasjoner), og der lagres informasjon om tid, sted og bilnummer i -10 år. Finnes det andre slike sniffere plassert ut på veiene?

- -

Personlig har jeg valgt å ikke bruke AutoPASS-brikke, for å gjøre -det vanskeligere og mer kostbart for de som vil invadere privatsfæren -og holde rede på hvor bilen min beveger seg til enhver tid. Jeg håper -flere vil gjøre det samme, selv om det gir litt høyere private -utgifter (dyrere bompassering). Vern om privatsfæren koster i disse -dager.

The Debian installer could be -a lot quicker. When we install more than 2000 packages in -Skolelinux / Debian Edu using -tasksel in the installer, unpacking the binary packages take forever. -A part of the slow I/O issue was discussed in -bug #613428 about too -much file system sync-ing done by dpkg, which is the package -responsible for unpacking the binary packages. Other parts (like code -executed by postinst scripts) might also sync to disk during -installation. All this sync-ing to disk do not really make sense to -me. If the machine crash half-way through, I start over, I do not try -to salvage the half installed system. So the failure sync-ing is -supposed to protect against, hardware or system crash, is not really -relevant while the installer is running.

- -

A few days ago, I thought of a way to get rid of all the file -system sync()-ing in a fairly non-intrusive way, without the need to -change the code in several packages. The idea is not new, but I have -not heard anyone propose the approach using dpkg-divert before. It -depend on the small and clever package -eatmydata, which -uses LD_PRELOAD to replace the system functions for syncing data to -disk with functions doing nothing, thus allowing programs to live -dangerous while speeding up disk I/O significantly. Instead of -modifying the implementation of dpkg, apt and tasksel (which are the -packages responsible for selecting, fetching and installing packages), -it occurred to me that we could just divert the programs away, replace -them with a simple shell wrapper calling -"eatmydata $program $@", to get the same effect. -Two days ago I decided to test the idea, and wrapped up a simple -implementation for the Debian Edu udeb.

- -

The effect was stunning. In my first test it reduced the running -time of the pkgsel step (installing tasks) from 64 to less than 44 -minutes (20 minutes shaved off the installation) on an old Dell -Latitude D505 machine. I am not quite sure what the optimised time -would have been, as I messed up the testing a bit, causing the debconf -priority to get low enough for two questions to pop up during -installation. As soon as I saw the questions I moved the installation -along, but do not know how long the question were holding up the -installation. I did some more measurements using Debian Edu Jessie, -and got these results. The time measured is the time stamp in -/var/log/syslog between the "pkgsel: starting tasksel" and the -"pkgsel: finishing up" lines, if you want to do the same measurement -yourself. In Debian Edu, the tasksel dialog do not show up, and the -timing thus do not depend on how quickly the user handle the tasksel -dialog.

This is a copy of +an +email I posted to the nikita-noark mailing list. Please follow up +there if you would like to discuss this topic. The background is that +we are making a free software archive system based on the Norwegian +Noark +5 standard for government archives.

+ +

I've been wondering a bit lately how trusted timestamps could be +stored in Noark 5. +Trusted +timestamps can be used to verify that some information +(document/file/checksum/metadata) have not been changed since a +specific time in the past. This is useful to verify the integrity of +the documents in the archive.

+ +

Then it occured to me, perhaps the trusted timestamps could be +stored as dokument variants (ie dokumentobjekt referered to from +dokumentbeskrivelse) with the filename set to the hash it is +stamping?

+ +

Given a "dokumentbeskrivelse" with an associated "dokumentobjekt", +a new dokumentobjekt is associated with "dokumentbeskrivelse" with the +same attributes as the stamped dokumentobjekt except these +attributes:

-
- - - - - +
    -
- - - - - +
  • format -> "RFC3161" +
  • mimeType -> "application/timestamp-reply" +
  • formatDetaljer -> "<source URL for timestamp service>" +
  • filenavn -> "<sjekksum>.tsr" -
  • - - - - - + - - - - - - +

    This assume a service following +IETF RFC 3161 is +used, which specifiy the given MIME type for replies and the .tsr file +ending for the content of such trusted timestamp. As far as I can +tell from the Noark 5 specifications, it is OK to have several +variants/renderings of a dokument attached to a given +dokumentbeskrivelse objekt. It might be stretching it a bit to make +some of these variants represent crypto-signatures useful for +verifying the document integrity instead of representing the dokument +itself.

    + +

    Using the source of the service in formatDetaljer allow several +timestamping services to be used. This is useful to spread the risk +of key compromise over several organisations. It would only be a +problem to trust the timestamps if all of the organisations are +compromised.

    + +

    The following oneliner on Linux can be used to generate the tsr +file. $input is the path to the file to checksum, and $sha256 is the +SHA-256 checksum of the file (ie the ".tsr" value mentioned +above).

    - - - - - - +

    +openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
    +  | curl -s -H "Content-Type: application/timestamp-query" \
    +      --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr

    The test is done using a netinst ISO on a USB stick, so some of the -time is spent downloading packages. The connection to the Internet -was 100Mbit/s during testing, so downloading should not be a -significant factor in the measurement. Download typically took a few -seconds to a few minutes, depending on the amount of packages being -installed.

    - -

    The speedup is implemented by using two hooks in -Debian -Installer, the pre-pkgsel.d hook to set up the diverts, and the -finish-install.d hook to remove the divert at the end of the -installation. I picked the pre-pkgsel.d hook instead of the -post-base-installer.d hook because I test using an ISO without the -eatmydata package included, and the post-base-installer.d hook in -Debian Edu can only operate on packages included in the ISO. The -negative effect of this is that I am unable to activate this -optimization for the kernel installation step in d-i. If the code is -moved to the post-base-installer.d hook, the speedup would be larger -for the entire installation.

    - -

    I've implemented this in the -debian-edu-install -git repository, and plan to provide the optimization as part of the -Debian Edu installation. If you want to test this yourself, you can -create two files in the installer (or in an udeb). One shell script -need do go into /usr/lib/pre-pkgsel.d/, with content like this:

    +

    To verify the timestamp, you first need to download the public key +of the trusted timestamp service, for example using this command:

    -#!/bin/sh
    -set -e
    -. /usr/share/debconf/confmodule
    -info() {
    -    logger -t my-pkgsel "info: $*"
    -}
    -error() {
    -    logger -t my-pkgsel "error: $*"
    -}
    -override_install() {
    -    apt-install eatmydata || true
    -    if [ -x /target/usr/bin/eatmydata ] ; then
    -        for bin in dpkg apt-get aptitude tasksel ; do
    -            file=/usr/bin/$bin
    -            # Test that the file exist and have not been diverted already.
    -            if [ -f /target$file ] ; then
    -                info "diverting $file using eatmydata"
    -                printf "#!/bin/sh\neatmydata $bin.distrib \"\$@\"\n" \
    -                    > /target$file.edu
    -                chmod 755 /target$file.edu
    -                in-target dpkg-divert --package debian-edu-config \
    -                    --rename --quiet --add $file
    -                ln -sf ./$bin.edu /target$file
    -            else
    -                error "unable to divert $file, as it is missing."
    -            fi
    -        done
    -    else
    -        error "unable to find /usr/bin/eatmydata after installing the eatmydata pacage"
    -    fi

    -override_install
    +wget -O ca-cert.txt \
    +  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
     

    -

    To clean up, another shell script should go into -/usr/lib/finish-install.d/ with code like this: +

    Note, the public key should be stored alongside the timestamps in +the archive to make sure it is also available 100 years from now. It +is probably a good idea to standardise how and were to store such +public keys, to make it easier to find for those trying to verify +documents 100 or 1000 years from now. :)

    + +

    The verification itself is a simple openssl command:

    -#! /bin/sh -e
    -. /usr/share/debconf/confmodule
    -error() {
    -    logger -t my-finish-install "error: $@"
    -}
    -remove_install_override() {
    -    for bin in dpkg apt-get aptitude tasksel ; do
    -        file=/usr/bin/$bin
    -        if [ -x /target$file.edu ] ; then
    -            rm /target$file
    -            in-target dpkg-divert --package debian-edu-config \
    -                --rename --quiet --remove $file
    -            rm /target$file.edu
    -        else
    -            error "Missing divert for $file."
    -        fi
    -    done
    -    sync # Flush file buffers before continuing
    -}
    -
    -remove_install_override
    +openssl ts -verify -data $inputfile -in $sha256.tsr \
    +  -CAfile ca-cert.txt -text
     

    -

    In Debian Edu, I placed both code fragments in a separate script -edu-eatmydata-install and call it from the pre-pkgsel.d and -finish-install.d scripts.

    - -

    By now you might ask if this change should get into the normal -Debian installer too? I suspect it should, but am not sure the -current debian-installer coordinators find it useful enough. It also -depend on the side effects of the change. I'm not aware of any, but I -guess we will see if the change is safe after some more testing. -Perhaps there is some package in Debian depending on sync() and -fsync() having effect? Perhaps it should go into its own udeb, to -allow those of us wanting to enable it to do so without affecting -everyone.

    - -

    Update 2014-09-24: Since a few days ago, enabling this optimization -will break installation of all programs using gnutls because of -bug #702711. An updated -eatmydata package in Debian will solve it.

    - -

    Update 2014-10-17: The bug mentioned above is fixed in testing and -the optimization work again. And I have discovered that the -dpkg-divert trick is not really needed and implemented a slightly -simpler approach as part of the debian-edu-install package. See -tools/edu-eatmydata-install in the source package.

    +

    Is there any reason this approach would not work? Is it somehow against +the Noark 5 specification?

    Yesterday, I had the pleasure of attending a talk with the -Norwegian Unix User Group about -the -OpenPGP keyserver pool sks-keyservers.net, and was very happy to -learn that there is a large set of publicly available key servers to -use when looking for peoples public key. So far I have used -subkeys.pgp.net, and some times wwwkeys.nl.pgp.net when the former -were misbehaving, but those days are ended. The servers I have used -up until yesterday have been slow and some times unavailable. I hope -those problems are gone now.

    - -

    Behind the round robin DNS entry of the -sks-keyservers.net service -there is a pool of more than 100 keyservers which are checked every -day to ensure they are well connected and up to date. It must be -better than what I have used so far. :)

    - -

    Yesterdays speaker told me that the service is the default -keyserver provided by the default configuration in GnuPG, but this do -not seem to be used in Debian. Perhaps it should?

    - -

    Anyway, I've updated my ~/.gnupg/options file to now include this -line:

    - -

    -keyserver pool.sks-keyservers.net
    -

    - -

    With GnuPG version 2 one can also locate the keyserver using SRV -entries in DNS. Just for fun, I did just that at work, so now every -user of GnuPG at the University of Oslo should find a OpenGPG -keyserver automatically should their need it:

    - -

    -% host -t srv _pgpkey-http._tcp.uio.no
    -_pgpkey-http._tcp.uio.no has SRV record 0 100 11371 pool.sks-keyservers.net.
    -%

    Now if only -the -HKP lookup protocol supported finding signature paths, I would be -very happy. It can look up a given key or search for a user ID, but I -normally do not want that, but to find a trust path from my key to -another key. Given a user ID or key ID, I would like to find (and -download) the keys representing a signature path from my key to the -key in question, to be able to get a trust path between the two keys. -This is as far as I can tell not possible today.

    Jeg oppdaget i dag at nettstedet som +publiserer offentlige postjournaler fra statlige etater, OEP, har +begynt å blokkerer enkelte typer webklienter fra å få tilgang. Vet +ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl +og curl. For å teste selv, kjør følgende:

    -

    Some free software like -Handbrake and -FFMPEG uses GPL/LGPL licenses and do -not have any such terms included, so for those, there is no -requirement to limit the use to personal and non-commercial.

    +
    +% curl -v -s https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
    +< HTTP/1.1 404 Not Found
    +% curl -v -s --header 'User-Agent:Opera/12.0' https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
    +< HTTP/1.1 200 OK
    +%
    +
    + +

    Her kan en se at tjenesten gir «404 Not Found» for curl i +standardoppsettet, mens den gir «200 OK» hvis curl hevder å være Opera +versjon 12.0. Offentlig elektronisk postjournal startet blokkeringen +2017-03-02.

    + +

    Blokkeringen vil gjøre det litt vanskeligere å maskinelt hente +informasjon fra oep.no. Kan blokkeringen være gjort for å hindre +automatisert innsamling av informasjon fra OEP, slik Pressens +Offentlighetsutvalg gjorde for å dokumentere hvordan departementene +hindrer innsyn i +rapporten +«Slik hindrer departementer innsyn» som ble publiserte i januar +2017. Det virker usannsynlig, da det jo er trivielt å bytte +User-Agent til noe nytt.

    + +

    Finnes det juridisk grunnlag for det offentlige å diskriminere +webklienter slik det gjøres her? Der tilgang gis eller ikke alt etter +hva klienten sier at den heter? Da OEP eies av DIFI og driftes av +Basefarm, finnes det kanskje noen dokumenter sendt mellom disse to +aktørene man kan be om innsyn i for å forstå hva som har skjedd. Men +postjournalen +til DIFI viser kun to dokumenter det siste året mellom DIFI og +Basefarm. +Mimes brønn neste, +tenker jeg.

    The Nikita +Noark 5 core project is implementing the Norwegian standard for +keeping an electronic archive of government documents. +The +Noark 5 standard document the requirement for data systems used by +the archives in the Norwegian government, and the Noark 5 web interface +specification document a REST web service for storing, searching and +retrieving documents and metadata in such archive. I've been involved +in the project since a few weeks before Christmas, when the Norwegian +Unix User Group +announced +it supported the project. I believe this is an important project, +and hope it can make it possible for the government archives in the +future to use free software to keep the archives we citizens depend +on. But as I do not hold such archive myself, personally my first use +case is to store and analyse public mail journal metadata published +from the government. I find it useful to have a clear use case in +mind when developing, to make sure the system scratches one of my +itches.

    + +

    If you would like to help make sure there is a free software +alternatives for the archives, please join our IRC channel +(#nikita on +irc.freenode.net) and +the +project mailing list.

    + +

    When I got involved, the web service could store metadata about +documents. But a few weeks ago, a new milestone was reached when it +became possible to store full text documents too. Yesterday, I +completed an implementation of a command line tool +archive-pdf to upload a PDF file to the archive using this +API. The tool is very simple at the moment, and find existing +fonds, series and +files while asking the user to select which one to use if more than +one exist. Once a file is identified, the PDF is associated with the +file and uploaded, using the title extracted from the PDF itself. The +process is fairly similar to visiting the archive, opening a cabinet, +locating a file and storing a piece of paper in the archive. Here is +a test run directly after populating the database with test data using +our API tester:

    + +

    +~/src//noark5-tester$ ./archive-pdf mangelmelding/mangler.pdf
    +using arkiv: Title of the test fonds created 2017-03-18T23:49:32.103446
    +using arkivdel: Title of the test series created 2017-03-18T23:49:32.103446
    +
    + 0 - Title of the test case file created 2017-03-18T23:49:32.103446
    + 1 - Title of the test file created 2017-03-18T23:49:32.103446
    +Select which mappe you want (or search term): 0
    +Uploading mangelmelding/mangler.pdf
    +  PDF title: Mangler i spesifikasjonsdokumentet for NOARK 5 Tjenestegrensesnitt
    +  File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
    +~/src//noark5-tester$
    +

    + +

    You can see here how the fonds (arkiv) and serie (arkivdel) only had +one option, while the user need to choose which file (mappe) to use +among the two created by the API tester. The archive-pdf +tool can be found in the git repository for the API tester.

    + +

    In the project, I have been mostly working on +the API +tester so far, while getting to know the code base. The API +tester currently use +the HATEOAS links +to traverse the entire exposed service API and verify that the exposed +operations and objects match the specification, as well as trying to +create objects holding metadata and uploading a simple XML file to +store. The tester has proved very useful for finding flaws in our +implementation, as well as flaws in the reference site and the +specification.

    + +

    The test document I uploaded is a summary of all the specification +defects we have collected so far while implementing the web service. +There are several unclear and conflicting parts of the specification, +and we have +started +writing down the questions we get from implementing it. We use a +format inspired by how The +Austin Group collect defect reports for the POSIX standard with +their +instructions for the MANTIS defect tracker system, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a request for a procedure for submitting defect reports :). + +

    The Nikita project is implemented using Java and Spring, and is +fairly easy to get up and running using Docker containers for those +that want to test the current code base. The API tester is +implemented in Python.
