The article refered to instructions -and <a href="https://www.youtube.com/watch?v=UjwgNd_as30">a recipe by -Keld Norman on Youtube on how to make a simple $7 IMSI Catcher</a>, and I decided to test them out.</p> - -<p>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.</p> - -<p>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.</p> - -<p>The updated and simpler recipe is thus to</p> - -<ol> - -<li>start with a Debian machine running Stretch or newer,</li> - -<li>build and install the gr-gsm package available from -<a href="http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/">http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/</a>,</li> - -<li>clone the git repostory from <a href="https://github.com/Oros42/IMSI-catcher">https://github.com/Oros42/IMSI-catcher</a>,</li> - -<li>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).</li> - -<li>go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.</li> - -</ol> - -<p>To make it even easier in the future to get this sniffer up and -running, I decided to package -<a href="https://github.com/ptrkrysik/gr-gsm/">the gr-gsm project</a> -for Debian (<a href="https://bugs.debian.org/871055">WNPP -#871055</a>), 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.</p> - -<p>I doubt this "IMSI cacher" is anywhere near as powerfull as -commercial tools like -<a href="https://www.thespyphone.com/portable-imsi-imei-catcher/">The -Spy Phone Portable IMSI / IMEI Catcher</a> or the -<a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">Harris -Stingray</a>, 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...</p> - -<p>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?</p> + Learn to program with Minetest on Debian + http://people.skolelinux.org/pere/blog/Learn_to_program_with_Minetest_on_Debian.html + http://people.skolelinux.org/pere/blog/Learn_to_program_with_Minetest_on_Debian.html + Sat, 15 Dec 2018 15:30:00 +0100 + <p>A fun way to learn how to program +<a href="https://www.python.org/">Python</a> is to follow the +instructions in the book +"<a href="https://nostarch.com/programwithminecraft">Learn to program +with Minecraft</a>", which introduces programming in Python to people +who like to play with Minecraft.

It is an open channel, allowing everyone +in Norway to publish videos on a TV channel with national coverage. +You can think of it as Youtube for national television. +In addition to distribution on RiksTV and Uninett, Frikanalen is also +available as a Kodi addon. The last few days I have updated the code +to add more features. A +<a href="https://kodi.tv/addon/plugins-video-add-ons/frikanalen-nett-tv">new +and improved version 0.0.3 Frikanalen addon</a> was just made +available via the Kodi repositories. This new version include a +option to browse videos by category, as well as free text search +in the video archive. It will now also show the video duration in the +video lists, which were missing earlier. A new and experimental +link to the HD video stream currently being worked on is provided, for +those that want to see what the <a href="https://casparcg.com/">CasparCG</a> +output look like. The alternative is the SD video stream, generated +using MLT. CasparCG is controlled by our +<a href="https://github.com/Frikanalen/mltplayout/">mltplayout +server</a> which instead of talking to mlt is giving PLAY instructions +to the CasparCG server when it is time to start a new program.</p> + +<p>By now, you are probably wondering what kind of content is being +played on the channel.

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 -<a href="https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden">Noark -5 standard</a> for government archives.</em></p> - -<p>I've been wondering a bit lately how trusted timestamps could be -stored in Noark 5. -<a href="https://en.wikipedia.org/wiki/Trusted_timestamping">Trusted -timestamps</a> 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.</p> - -<p>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?</p> - -<p>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:</p> - -<ul> - -<li>format -> "RFC3161" -<li>mimeType -> "application/timestamp-reply" -<li>formatDetaljer -> "&lt;source URL for timestamp service&gt;" -<li>filenavn -> "&lt;sjekksum&gt;.tsr" - -</ul> - -<p>This assume a service following -<a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> 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.</p> - -<p>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.</p> - -<p>The following oneliner on Linux can be used to generate the tsr -file. $input is the path to the file to checksum, and $sha256 is the -SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned -above).</p> - -<p><blockquote><pre> -openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \ - | curl -s -H "Content-Type: application/timestamp-query" \ - --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr -</pre></blockquote></p> - -<p>To verify the timestamp, you first need to download the public key -of the trusted timestamp service, for example using this command:</p> - -<p><blockquote><pre> -wget -O ca-cert.txt \ - https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt -</pre></blockquote></p> - -<p>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. :)</p> - -<p>The verification itself is a simple openssl command:</p> - -<p><blockquote><pre> -openssl ts -verify -data $inputfile -in $sha256.tsr \ - -CAfile ca-cert.txt -text -</pre></blockquote></p> - -<p>Is there any reason this approach would not work? Is it somehow against -the Noark 5 specification?</p> + Time for an official MIME type for patches? + http://people.skolelinux.org/pere/blog/Time_for_an_official_MIME_type_for_patches_.html + http://people.skolelinux.org/pere/blog/Time_for_an_official_MIME_type_for_patches_.html + Thu, 1 Nov 2018 08:15:00 +0100 + <p>As part of my involvement in +<a href="https://gitlab.com/OsloMet-ABI/nikita-noark5-core">the Nikita +archive API project</a>, I've been importing a fairly large lump of +emails into a test instance of the archive to see how well this would +go. I picked a subset of <a href="https://notmuchmail.org/">my +notmuch email database</a>, all public emails sent to me via +@lists.debian.org, giving me a set of around 216 000 emails to import. +In the process, I had a look at the various attachments included in +these emails, to figure out what to do with attachments, and noticed +that one of the most common attachment formats do not have +<a href="https://www.iana.org/assignments/media-types/media-types.xhtml">an +official MIME type</a> registered with IANA/IETF.

It is amazing what kind of equipment +show up there. I've been wondering for a while if it was possible to +measure how well this equipment is working together, and decided to +see how far I could get using free software. After trawling the web I +came across an article from DIY Audio and Video on +<a href="https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/">Speaker +Testing and Analysis</a> describing how to test speakers, and it listing +several software options, among them +<a href="https://sourceforge.net/projects/audmes/">AUDio MEasurement +System (AUDMES)</a>. It is the only free software system I could find +focusing on measuring speakers and audio frequency response. In the +process I also found an interesting article from NOVO on +<a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding +Speaker Specifications and Frequency Response</a> and an article from +ecoustics on +<a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding +Speaker Frequency Response</a>, with a lot of information on what to +look for and how to interpret the graphs. Armed with this knowledge, +I set out to measure the state of my speakers.</p> + +<p>The first hurdle was that AUDMES hadn't seen a commit for 10 years +and did not build with current compilers and libraries. I got in +touch with its author, who no longer was spending time on the program +but gave me write access to the subversion repository on Sourceforge. +The end result is that now the code build on Linux and is capable of +saving and loading the collected frequency response data in CSV +format. The application is quite nice and flexible, and I was able to +select the input and output audio interfaces independently. This made +it possible to use a USB mixer as the input source, while sending +output via my laptop headphone connection. I lacked the hardware and +cabling to figure out a different way to get independent cabling to +speakers and microphone.</p> + +<p>Using this setup I could see how a large range of high frequencies +apparently were not making it out of my speakers. The picture show +the frequency response measurement of one of the speakers. Note the +frequency lines seem to be slightly misaligned, compared to the CSV +output from the program. I can not hear several of these are high +frequencies, according to measurement from +<a href="http://freehearingtestsoftware.com">Free Hearing Test +Software</a>, an freeware system to measure your hearing (still +looking for a free software alternative), so I do not know if they are +coming out out the speakers. I thus do not quite know how to figure +out if the missing frequencies is a problem with the microphone, the +amplifier or the speakers, but I managed to rule out the audio card in my +PC by measuring my Bose noise canceling headset using its own +microphone. This setup was able to see the high frequency tones, so +the problem with my stereo had to be in the amplifier or speakers.</p> + +<p>Anyway, to try to role out one factor I ended up picking up a new +set of speakers at a flee marked, and these work a lot better than the +old speakers, so I guess the microphone and amplifier is OK. If you +need to measure your own speakers, check out AUDMES. If more people +get involved, perhaps the project could become good enough to +<a href="https://bugs.debian.org/910876">include in Debian</a>? And if +you know of some other free software to measure speakers and amplifier +performance, please let me know.

It is used all by all sorts of +content providers, from national TV stations like +<a href="https://www.nrk.no/">NRK</a>, Linux distributors like +<a href="https://www.debian.org/">Debian</a> and +<a href="https://www.ubuntu.com/">Ubuntu</a>, and of course the +<a href="https://archive.org/">Internet archive</A>. + +<p>Almost a month ago +<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">a new +package adding Bittorrent support to VLC</a> became available in +Debian testing and unstable. To test it, simply install it like +this:</p> + +<p><pre> +apt install vlc-plugin-bittorrent +</pre></p> + +<p>Since the plugin was made available for the first time in Debian, +several improvements have been made to it. In version 2.2-4, now +available in both testing and unstable, a desktop file is provided to +teach browsers to start VLC when the user click on torrent files or +magnet links. The last part is thanks to me finally understanding +what the strange x-scheme-handler style MIME types in desktop files +are used for. By adding x-scheme-handler/magnet to the MimeType entry +in the desktop file, at least the browsers Firefox and Chromium will +suggest to start VLC when selecting a magnet URI on a web page. The +end result is that now, with the plugin installed in Buster and Sid, +one can visit any +<a href="https://archive.org/details/CopyingIsNotTheft1080p">Internet +Archive page with movies</a> using a web browser and click on the +torrent link to start streaming the movie.</p> + +<p>Note, there is still some misfeatures in the plugin. One is the +fact that it will hang and +<a href="https://github.com/johang/vlc-bittorrent/issues/13">block VLC +from exiting until the torrent streaming starts</a>. Another is the +fact that it +<a href="https://github.com/johang/vlc-bittorrent/issues/9">will pick +and play a random file in a multi file torrent</a>. This is not +always the video file you want. Combined with the first it can be a +bit hard to get the video streaming going. But when it work, it seem +to do a good job.</p> + +<p>For the Debian packaging, I would love to find a good way to test +if the plugin work with VLC using autopkgtest. I tried, but do not +know enough of the inner workings of VLC to get it working. For now +the autopkgtest script is only checking if the .so file was +successfully loaded by VLC.
