+                <pubDate>Wed, 9 Aug 2017 23:59:00 +0200</pubDate>
+               <description>&lt;p&gt;On friday, I came across an interesting article in the Norwegian
+web based ICT news magazine digi.no on
+&lt;a href=&quot;https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588&quot;&gt;how
+to collect the IMSI numbers of nearby cell phones&lt;/a&gt; using the cheap
+DVB-T software defined radios.  The article refered to instructions
+and &lt;a href=&quot;https://www.youtube.com/watch?v=UjwgNd_as30&quot;&gt;a recipe by
+Keld Norman on Youtube on how to make a simple $7 IMSI Catcher&lt;/a&gt;, and I decided to test them out.&lt;/p&gt;
+
+&lt;p&gt;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-&gt;pip-&gt;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.&lt;/p&gt;
+
+&lt;p&gt;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&#39;ve been testing the
+collector for a few days now.&lt;/p&gt;
+
+&lt;p&gt;The updated and simpler recipe is thus to&lt;/p&gt;
+
+&lt;ol&gt;
+
+&lt;li&gt;start with a Debian machine running Stretch or newer,&lt;/li&gt;
+
+&lt;li&gt;build and install the gr-gsm package available from
+&lt;a href=&quot;http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/&quot;&gt;http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/&lt;/a&gt;,&lt;/li&gt;
+
+&lt;li&gt;clone the git repostory from &lt;a href=&quot;https://github.com/Oros42/IMSI-catcher&quot;&gt;https://github.com/Oros42/IMSI-catcher&lt;/a&gt;,&lt;/li&gt;
+
+&lt;li&gt;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).&lt;/li&gt;
+
+&lt;li&gt;go into the IMSI-catcher directory and run &#39;sudo python simple_IMSI-catcher.py&#39; to extract the IMSI numbers.&lt;/li&gt;
+
+&lt;/ol&gt;
+
+&lt;p&gt;To make it even easier in the future to get this sniffer up and
+running, I decided to package
+&lt;a href=&quot;https://github.com/ptrkrysik/gr-gsm/&quot;&gt;the gr-gsm project&lt;/a&gt;
+for Debian (&lt;a href=&quot;https://bugs.debian.org/871055&quot;&gt;WNPP
+#871055&lt;/a&gt;), 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.&lt;/p&gt;
+
+&lt;p&gt;I doubt this &quot;IMSI cacher&quot; is anywhere near as powerfull as
+commercial tools like
+&lt;a href=&quot;https://www.thespyphone.com/portable-imsi-imei-catcher/&quot;&gt;The
+Spy Phone Portable IMSI / IMEI Catcher&lt;/a&gt; or the
+&lt;a href=&quot;https://en.wikipedia.org/wiki/Stingray_phone_tracker&quot;&gt;Harris
+Stingray&lt;/a&gt;, 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...&lt;/p&gt;
+
+&lt;p&gt;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?&lt;/p&gt;

+
+&lt;p&gt;I finally received a copy of the Norwegian Bokmål edition of
+&quot;&lt;a href=&quot;https://debian-handbook.info/&quot;&gt;The Debian Administrator&#39;s
+Handbook&lt;/a&gt;&quot;.  This test copy arrived in the mail a few days ago, and
+I am very happy to hold the result in my hand.   We spent around one and a half year translating it. This paperbook edition
+&lt;a href=&quot;https://debian-handbook.info/get/#norwegian&quot;&gt;is available
+from lulu.com&lt;/a&gt;.  If you buy it quickly, you save 25% on the list
+price.  The book is also available for download in electronic form as
+PDF, EPUB and Mobipocket, as can be
+&lt;a href=&quot;https://debian-handbook.info/browse/nb-NO/stable/&quot;&gt;read online
+as a web page&lt;/a&gt;.&lt;/p&gt;
+
+&lt;p&gt;This is the second book I publish (the first was the book
+&quot;&lt;a href=&quot;http://free-culture.cc/&quot;&gt;Free Culture&lt;/a&gt;&quot; by Lawrence Lessig
+in
+&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/free-culture/paperback/product-22440520.html&quot;&gt;English&lt;/a&gt;,

+&lt;a href=&quot;http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html&quot;&gt;Norwegian
+Bokmål&lt;/a&gt;), and I am very excited to finally wrap up this
+project.  I hope
+&quot;&lt;a href=&quot;http://www.lulu.com/shop/rapha%C3%ABl-hertzog-and-roland-mas/h%C3%A5ndbok-for-debian-administratoren/paperback/product-23262290.html&quot;&gt;Håndbok

+               <description>&lt;p&gt;Jeg kom over teksten
+«&lt;a href=&quot;https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/&quot;&gt;Killing
+car privacy by federal mandate&lt;/a&gt;» 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.
+
+&lt;p&gt;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
+«&lt;a href=&quot;https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933&quot;&gt;Informasjonssikkerhet
+i AutoPASS-brikker&lt;/a&gt;» av Trond Foss:&lt;/p&gt;
+
+&lt;p&gt;&lt;blockquote&gt;
+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
+  integritet.»
+&lt;/blockquote&gt;&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

+editions of the classic &lt;a href=&quot;http://www.free-culture.cc/&quot;&gt;Free
+Culture book&lt;/a&gt; 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 &lt;a href=&quot;https://creativecommons.org/&quot;&gt;Creative
+Commons Corporation&lt;/a&gt;, 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

+ &lt;li&gt;Added support for docker container images.&lt;/li&gt;
+ &lt;li&gt;Added simple API browser implemented in JavaScript/Angular.&lt;/li&gt;
+ &lt;li&gt;Started on archive client implemented in JavaScript/Angular.&lt;/li&gt;
+ &lt;li&gt;Started on prototype to show the public mail journal.&lt;/li&gt;
+ &lt;li&gt;Improved performance by disabling Sprint FileWatcher.&lt;/li&gt;
+ &lt;li&gt;Added support for &#39;arkivskaper&#39;, &#39;saksmappe&#39; and &#39;journalpost&#39;.&lt;/li&gt;
+ &lt;li&gt;Added support for some metadata codelists.&lt;/li&gt;
+ &lt;li&gt;Added support for Cross-origin resource sharing (CORS).&lt;/li&gt;
+ &lt;li&gt;Changed login method from Basic Auth to JSON Web Token (RFC 7519)
+   style.&lt;/li&gt;
+ &lt;li&gt;Added support for GET-ing ny-* URLs.&lt;/li&gt;
+ &lt;li&gt;Added support for modifying entities using PUT and eTag.&lt;/li&gt;
+ &lt;li&gt;Added support for returning XML output on request.&lt;/li&gt;
+ &lt;li&gt;Removed support for English field and class names, limiting ourself
+   to the official names.&lt;/li&gt;
+ &lt;li&gt;...&lt;/li&gt;
+ 
+&lt;/ul&gt;

-               <description>&lt;p&gt;Over the years, administrating thousand of NFS mounting linux
-computers at the time, I often needed a way to detect if the machine
-was experiencing NFS hang.  If you try to use &lt;tt&gt;df&lt;/tt&gt; or look at a
-file or directory affected by the hang, the process (and possibly the
-shell) will hang too.  So you want to be able to detect this without
-risking the detection process getting stuck too.  It has not been
-obvious how to do this.  When the hang has lasted a while, it is
-possible to find messages like these in dmesg:&lt;/p&gt;
-
-&lt;p&gt;&lt;blockquote&gt;
-nfs: server nfsserver not responding, still trying
-&lt;br&gt;nfs: server nfsserver OK
-&lt;/blockquote&gt;&lt;/p&gt;
-  
-&lt;p&gt;It is hard to know if the hang is still going on, and it is hard to
-be sure looking in dmesg is going to work.  If there are lots of other
-messages in dmesg the lines might have rotated out of site before they
-are noticed.&lt;/p&gt;
-
-&lt;p&gt;While reading through the nfs client implementation in linux kernel
-code, I came across some statistics that seem to give a way to detect
-it.  The om_timeouts sunrpc value in the kernel will increase every
-time the above log entry is inserted into dmesg.  And after digging a
-bit further, I discovered that this value show up in
-/proc/self/mountstats on Linux.&lt;/p&gt;
-
-&lt;p&gt;The mountstats content seem to be shared between files using the
-same file system context, so it is enough to check one of the
-mountstats files to get the state of the mount point for the machine.
-I assume this will not show lazy umounted NFS points, nor NFS mount
-points in a different process context (ie with a different filesystem

-[...]
-&lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
-
-&lt;p&gt;The key number to look at is the third number in the per-op list.
-It is the number of NFS timeouts experiences per file system
-operation.  Here 22 write timeouts and 5 access timeouts.  If these
-numbers are increasing, I believe the machine is experiencing NFS
-hang.  Unfortunately the timeout value do not start to increase right
-away.  The NFS operations need to time out first, and this can take a
-while.  The exact timeout value depend on the setup.  For example the
-defaults for TCP and UDP mount points are quite different, and the
-timeout value is affected by the soft, hard, timeo and retrans NFS
-mount options.&lt;/p&gt;
-
-&lt;p&gt;The only way I have been able to get working on Debian and RedHat
-Enterprise Linux for getting the timeout count is to peek in /proc/.
-But according to
-&lt;ahref=&quot;http://docs.oracle.com/cd/E19253-01/816-4555/netmonitor-12/index.html&quot;&gt;Solaris
-10 System Administration Guide: Network Services&lt;/a&gt;, the &#39;nfsstat -c&#39;
-command can be used to get these timeout values.  But this do not work
-on Linux, as far as I can tell.  I
-&lt;ahref=&quot;http://bugs.debian.org/857043&quot;&gt;asked Debian about this&lt;/a&gt;,
-but have not seen any replies yet.&lt;/p&gt;
-
-&lt;p&gt;Is there a better way to figure out if a Linux NFS client is
-experiencing NFS hangs?  Is there a way to detect which processes are
-affected?  Is there a way to get the NFS mount going quickly once the
-network problem causing the NFS hang has been cleared?  I would very
-much welcome some clues, as we regularly run into NFS hangs.&lt;/p&gt;

-               <description>&lt;p&gt;So the new president in the United States of America claim to be
-surprised to discover that he was wiretapped during the election
-before he was elected president.  He even claim this must be illegal.
-Well, doh, if it is one thing the confirmations from Snowden
-documented, it is that the entire population in USA is wiretapped, one
-way or another.  Of course the president candidates were wiretapped,
-alongside the senators, judges and the rest of the people in USA.&lt;/p&gt;
-
-&lt;p&gt;Next, the Federal Bureau of Investigation ask the Department of
-Justice to go public rejecting the claims that Donald Trump was
-wiretapped illegally.  I fail to see the relevance, given that I am
-sure the surveillance industry in USA believe they have all the legal
-backing they need to conduct mass surveillance on the entire
-world.&lt;/p&gt;
-
-&lt;p&gt;There is even the director of the FBI stating that he never saw an
-order requesting wiretapping of Donald Trump.  That is not very
-surprising, given how the FISA court work, with all its activity being
-secret.  Perhaps he only heard about it?&lt;/p&gt;
-
-&lt;p&gt;What I find most sad in this story is how Norwegian journalists
-present it.  In a news reports the other day in the radio from the
-Norwegian National broadcasting Company (NRK), I heard the journalist
-claim that &#39;the FBI denies any wiretapping&#39;, while the reality is that
-&#39;the FBI denies any illegal wiretapping&#39;.  There is a fundamental and
-important difference, and it make me sad that the journalists are
-unable to grasp it.&lt;/p&gt;
-
-&lt;p&gt;&lt;strong&gt;Update 2017-03-13:&lt;/strong&gt; Look like
-&lt;a href=&quot;https://theintercept.com/2017/03/13/rand-paul-is-right-nsa-routinely-monitors-americans-communications-without-warrants/&quot;&gt;The

-we are working on the proof reading to ensure consistent language and
-use of correct computer science terms.  The plan is to make the book
-available on paper, as well as in electronic form.  For that to

-               <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Unlimited_randomness_with_the_ChaosKey_.html</guid>
-                <pubDate>Wed, 1 Mar 2017 20:50:00 +0100</pubDate>
-               <description>&lt;p&gt;A few days ago I ordered a small batch of
-&lt;a href=&quot;http://altusmetrum.org/ChaosKey/&quot;&gt;the ChaosKey&lt;/a&gt;, a small
-USB dongle for generating entropy created by Bdale Garbee and Keith
-Packard.  Yesterday it arrived, and I am very happy to report that it
-work great!  According to its designers, to get it to work out of the
-box, you need the Linux kernel version 4.1 or later.  I tested on a
-Debian Stretch machine (kernel version 4.9), and there it worked just
-fine, increasing the available entropy very quickly.  I wrote a small
-test oneliner to test.  It first print the current entropy level,
-drain /dev/random, and then print the entropy level for five seconds.
-Here is the situation without the ChaosKey inserted:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-% cat /proc/sys/kernel/random/entropy_avail; \
-  dd bs=1M if=/dev/random of=/dev/null count=1; \
-  for n in $(seq 1 5); do \
-     cat /proc/sys/kernel/random/entropy_avail; \
-     sleep 1; \
-  done

-12
-17
-21
-%
-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;The entropy level increases by 3-4 every second.  In such case any
-application requiring random bits (like a HTTPS enabled web server)
-will halt and wait for more entrpy.  And here is the situation with
-the ChaosKey inserted:&lt;/p&gt;
-
-&lt;blockquote&gt;&lt;pre&gt;
-% cat /proc/sys/kernel/random/entropy_avail; \
-  dd bs=1M if=/dev/random of=/dev/null count=1; \
-  for n in $(seq 1 5); do \
-     cat /proc/sys/kernel/random/entropy_avail; \
-     sleep 1; \
-  done

-&lt;/pre&gt;&lt;/blockquote&gt;
-
-&lt;p&gt;Quite the difference. :) I bought a few more than I need, in case
-someone want to buy one here in Norway. :)&lt;/p&gt;
-
-&lt;p&gt;Update: The dongle was presented at Debconf last year.  You might
-find &lt;a href=&quot;https://debconf16.debconf.org/talks/94/&quot;&gt;the talk
-recording illuminating&lt;/a&gt;.  It explains exactly what the source of
-randomness is, if you are unable to spot it from the schema drawing
-available from the ChaosKey web site linked at the start of this blog
-post.&lt;/p&gt;

-               <description>&lt;p&gt;I just noticed
-&lt;a href=&quot;http://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing&quot;&gt;the
-new Norwegian proposal for archiving rules in the goverment&lt;/a&gt; list
-&lt;a href=&quot;http://www.ecma-international.org/publications/standards/Ecma-376.htm&quot;&gt;ECMA-376&lt;/a&gt;
-/ ISO/IEC 29500 (aka OOXML) as valid formats to put in long term
-storage.  Luckily such files will only be accepted based on
-pre-approval from the National Archive.  Allowing OOXML files to be
-used for long term storage might seem like a good idea as long as we
-forget that there are plenty of ways for a &quot;valid&quot; OOXML document to
-have content with no defined interpretation in the standard, which
-lead to a question and an idea.&lt;/p&gt;
-
-&lt;p&gt;Is there any tool to detect if a OOXML document depend on such
-undefined behaviour?  It would be useful for the National Archive (and
-anyone else interested in verifying that a document is well defined)
-to have such tool available when considering to approve the use of
-OOXML.  I&#39;m aware of the
-&lt;a href=&quot;https://github.com/arlm/officeotron/&quot;&gt;officeotron OOXML
-validator&lt;/a&gt;, but do not know how complete it is nor if it will
-report use of undefined behaviour.  Are there other similar tools
-available?  Please send me an email if you know of any such tool.&lt;/p&gt;
