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.

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.

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.

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.

But some times I want to integrate the timestamping +in other code, and recently I needed to integrate it into Python. +After searching a bit, I found +<a href="https://dev.entrouvert.org/projects/python-rfc3161">the +rfc3161 library</a> which seemed like a good fit, but I soon +discovered it only worked for python version 2, and I needed something +that work with python version 3. Luckily I next came across +<a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>, +a fork of the original rfc3161 library. Not only is it working with +python 3, it have fixed a few of the bugs in the original library, and +it has an active maintainer. I decided to wrap it up and make it +<a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in +Debian</a>, and a few days ago it entered Debian unstable and testing.</p> + +<p>Using the library is fairly straight forward. The only slightly +problematic step is to fetch the required certificates to verify the +timestamp.

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.

I've been keeping an eye on virtual +currencies for many years, and it is part of the reason a few months +ago, I started writing a python library for collecting currency +exchange rates and trade on virtual currency exchanges. I decided to +name the end result valutakrambod, which perhaps can be translated to +small currency shop.</p> + +<p>The library uses the tornado python library to handle HTTP and +websocket connections, and provide a asynchronous system for +connecting to and tracking several services. The code is available +from +<a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p> + +</p>There are two example clients of the library. One is very simple and +list every updated buy/sell price received from the various services. +This code is started by running bin/btc-rates and call the client code +in valutakrambod/client.py. The simple client look like this:</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 +import functools +import tornado.ioloop +import valutakrambod +class SimpleClient(object): + def __init__(self): + self.services = [] + self.streams = [] + pass + def newdata(self, service, pair, changed): + print("%-15s %s-%s: %8.3f %8.3f" % ( + service.servicename(), + pair[0], + pair[1], + service.rates[pair]['ask'], + service.rates[pair]['bid']) + ) + async def refresh(self, service): + await service.fetchRates(service.wantedpairs) + def run(self): + self.ioloop = tornado.ioloop.IOLoop.current() + self.services = valutakrambod.service.knownServices() + for e in self.services: + service = e() + service.subscribe(self.newdata) + stream = service.websocket() + if stream: + self.streams.append(stream) + else: + # Fetch information from non-streaming services immediately + self.ioloop.call_later(len(self.services), + functools.partial(self.refresh, service)) + # as well as regularly + service.periodicUpdate(60) + for stream in self.streams: + stream.connect() + try: + self.ioloop.start() + except KeyboardInterrupt: + print("Interrupted by keyboard, closing all connections.") + pass + for stream in self.streams: + stream.close() </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>The library client loops over all known "public" services, +initialises it, subscribes to any updates from the service, checks and +activates websocket streaming if the service provide it, and if no +streaming is supported, fetches information from the service and sets +up a periodic update every 60 seconds. The output from this client +can look like this:</p> <p><blockquote><pre> -wget -O ca-cert.txt \ - https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt +Bl3p BTC-EUR: 5687.110 5653.690 +Bl3p BTC-EUR: 5687.110 5653.690 +Bl3p BTC-EUR: 5687.110 5653.690 +Hitbtc BTC-USD: 6594.560 6593.690 +Hitbtc BTC-USD: 6594.560 6593.690 +Bl3p BTC-EUR: 5687.110 5653.690 +Hitbtc BTC-USD: 6594.570 6593.690 +Bitstamp EUR-USD: 1.159 1.154 +Hitbtc BTC-USD: 6594.570 6593.690 +Hitbtc BTC-USD: 6594.580 6593.690 +Hitbtc BTC-USD: 6594.580 6593.690 +Hitbtc BTC-USD: 6594.580 6593.690 +Bl3p BTC-EUR: 5687.110 5653.690 +Paymium BTC-EUR: 5680.000 5620.240 </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.

I uploaded it to NEW a few days ago, +and am very happy to report that it +<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">entered +Debian</a> a few hours ago, and should be available in Debian/Unstable +tomorrow, and Debian/Testing in a few days.</p> + +<p>With the vlc-plugin-bittorrent package installed you should be able +to stream videos using a simple call to</p> + +<p><blockquote><pre> +vlc https://archive.org/download/TheGoat/TheGoat_archive.torrent +</pre></blockquote></p> + +</p>It can handle magnet links too. Now if only native vlc had +bittorrent support. Then a lot more would be helping each other to +share public domain and creative commons movies. The plugin need some +stability work with seeking and picking the right file in a torrent +with many files, but is already usable. Please note that the plugin +is not removing downloaded files when vlc is stopped, so it can fill +up your disk if you are not careful. Have fun. :)</p> + +<p>I would love to get help maintaining this package.

Som en kan se er det ikke mye tid igjen før fristen -som går ut på søndag. Denne forskriften er det som lister opp hvilke -formater det er greit å arkivere i -<a href="http://www.arkivverket.no/arkivverket/Offentleg-forvalting/Noark/Noark-5">Noark -5-løsninger</a> i Norge.</p> - -<p>Jeg fant høringsdokumentene hos -<a href="https://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing">Norsk -Arkivråd</a> etter å ha blitt tipset på epostlisten til -<a href="https://github.com/hiOA-ABI/nikita-noark5-core">fri -programvareprosjektet Nikita Noark5-Core</a>, som lager et Noark 5 -Tjenestegresesnitt. Jeg er involvert i Nikita-prosjektet og takket -være min interesse for tjenestegrensesnittsprosjektet har jeg lest en -god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget -at standard epost ikke er på listen over godkjente formater som kan -arkiveres. Høringen med frist søndag er en glimrende mulighet til å -forsøke å gjøre noe med det. Jeg holder på med -<a href="https://github.com/petterreinholdtsen/noark5-tester/blob/master/docs/hoering-arkivforskrift.tex">egen -høringsuttalelse</a>, og lurer på om andre er interessert i å støtte -forslaget om å tillate arkivering av epost som epost i arkivet.</p> - -<p>Er du igang med å skrive egen høringsuttalelse allerede? I så fall -kan du jo vurdere å ta med en formulering om epost-lagring. Jeg tror -ikke det trengs så mye. Her et kort forslag til tekst:</p> - -<p><blockquote> - - <p>Viser til høring sendt ut 2017-02-17 (Riksarkivarens referanse - 2016/9840 HELHJO), og tillater oss å sende inn noen innspill om - revisjon av Forskrift om utfyllende tekniske og arkivfaglige - bestemmelser om behandling av offentlige arkiver (Riksarkivarens - forskrift).</p> - - <p>Svært mye av vår kommuikasjon foregår i dag på e-post.  Vi - foreslår derfor at Internett-e-post, slik det er beskrevet i IETF - RFC 5322, - <a href="https://tools.ietf.org/html/rfc5322">https://tools.ietf.org/html/rfc5322</a>. bør - inn som godkjent dokumentformat.  Vi foreslår at forskriftens - oversikt over godkjente dokumentformater ved innlevering i § 5-16 - endres til å ta med Internett-e-post.</p> - -</blockquote></p> - -<p>Som del av arbeidet med tjenestegrensesnitt har vi testet hvordan -epost kan lagres i en Noark 5-struktur, og holder på å skrive et -forslag om hvordan dette kan gjøres som vil bli sendt over til -arkivverket så snart det er ferdig.

After searching the +web for API access to the Youtube plugin and testing a bit, I managed +to find a recipe that worked. If you got a kodi instance with its API +available from http://kodihost/jsonrpc, you can try the following to +have check out a nice cover band.</p> + +<p><blockquote><pre>curl --silent --header 'Content-Type: application/json' \ + --data-binary '{ "id": 1, "jsonrpc": "2.0", "method": "Player.Open", + "params": {"item": { "file": + "plugin://plugin.video.youtube/play/?video_id=LuRGVM9O0qg" } } }' \ + http://projector.local/jsonrpc</pre></blockquote></p> + +<p>I've extended kodi-stream program to take a video source as its +first argument. It can now handle direct video links, youtube links +and 'desktop' to stream my desktop to Kodi. It is almost like a +Chromecast. :)</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> - Offentlig elektronisk postjournal blokkerer tilgang for utvalgte webklienter - http://people.skolelinux.org/pere/blog/Offentlig_elektronisk_postjournal_blokkerer_tilgang_for_utvalgte_webklienter.html - http://people.skolelinux.org/pere/blog/Offentlig_elektronisk_postjournal_blokkerer_tilgang_for_utvalgte_webklienter.html - Thu, 20 Apr 2017 13:00:00 +0200 - <p>Jeg oppdaget i dag at <a href="https://www.oep.no/">nettstedet som -publiserer offentlige postjournaler fra statlige etater</a>, 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:</p> - -<blockquote><pre> -% 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 -% -</pre></blockquote> - -<p>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.</p> - -<p>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 -<a href="http://presse.no/dette-mener-np/undergraver-offentlighetsloven/">rapporten -«Slik hindrer departementer innsyn» som ble publiserte i januar -2017</a>. Det virker usannsynlig, da det jo er trivielt å bytte -User-Agent til noe nytt.</p> - -<p>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?
