Myers, Licensing Associate -with the MPEG LA:</p> - -<p><blockquote> -<p>Thank you for your message and for your interest in MPEG LA. We -appreciate hearing from you and I will be happy to assist you.</p> - -<p>As you are aware, MPEG LA offers our AVC Patent Portfolio License -which provides coverage under patents that are essential for use of -the AVC/H.264 Standard (MPEG-4 Part 10). Specifically, coverage is -provided for end products and video content that make use of AVC/H.264 -technology. Accordingly, the party offering such end products and -video to End Users concludes the AVC License and is responsible for -paying the applicable royalties.</p> - -<p>Regarding Internet Broadcast AVC Video, the AVC License generally -defines such content to be video that is distributed to End Users over -the Internet free-of-charge. Therefore, if a party offers a service -which allows users to upload AVC/H.264 video to its website, and such -AVC Video is delivered to End Users for free, then such video would -receive coverage under the sublicense for Internet Broadcast AVC -Video, which is not subject to any royalties for the life of the AVC -License. This would also apply in the scenario where a user creates a -free online account in order to receive a customized offering of free -AVC Video content. In other words, as long as the End User is given -access to or views AVC Video content at no cost to the End User, then -no royalties would be payable under our AVC License.</p> - -<p>On the other hand, if End Users pay for access to AVC Video for a -specific period of time (e.g., one month, one year, etc.), then such -video would constitute Subscription AVC Video. In cases where AVC -Video is delivered to End Users on a pay-per-view basis, then such -content would constitute Title-by-Title AVC Video. If a party offers -Subscription or Title-by-Title AVC Video to End Users, then they would -be responsible for paying the applicable royalties you noted below.</p> - -<p>Finally, in the case where AVC Video is distributed for free -through an "over-the-air, satellite and/or cable transmission", then -such content would constitute Free Television AVC Video and would be -subject to the applicable royalties.</p> - -<p>For your reference, I have attached -<a href="http://people.skolelinux.org/pere/blog/images/2015-07-07-mpegla.pdf">a -.pdf copy of the AVC License</a>. You will find the relevant -sublicense information regarding AVC Video in Sections 2.2 through -2.5, and the corresponding royalties in Section 3.1.2 through 3.1.4. -You will also find the definitions of Title-by-Title AVC Video, -Subscription AVC Video, Free Television AVC Video, and Internet -Broadcast AVC Video in Section 1 of the License. Please note that the -electronic copy is provided for informational purposes only and cannot -be used for execution.</p> - -<p>I hope the above information is helpful. If you have additional -questions or need further assistance with the AVC License, please feel -free to contact me directly.</p> -</blockquote></p> - -<p>Having a fresh copy of the license text was useful, and knowing -that the definition of Title-by-Title required payment per title made -me aware that my earlier understanding of that phrase had been wrong. -But I still had a few questions:</p> - -<p><blockquote> -<p>I have a small followup question. Would it be possible for me to get -a license with MPEG LA even if there are no royalties to be paid? The -reason I ask, is that some video related products have a copyright -clause limiting their use without a license with MPEG LA. The clauses -typically look similar to this: - -<p><blockquote> - This product is licensed under the AVC patent portfolio license for - the personal and non-commercial use of a consumer to (a) encode - video in compliance with the AVC standard ("AVC video") and/or (b) - decode AVC video that was encoded by a consumer engaged in a - personal and non-commercial activity and/or AVC video that was - obtained from a video provider licensed to provide AVC video. No - license is granted or shall be implied for any other use. additional - information may be obtained from MPEG LA L.L.C. -</blockquote></p> - -<p>It is unclear to me if this clause mean that I need to enter into -an agreement with MPEG LA to use the product in question, even if -there are no royalties to be paid to MPEG LA. I suspect it will -differ depending on the jurisdiction, and mine is Norway. What is -MPEG LAs view on this?</p> -</blockquote></p> - -<p>According to the answer, MPEG LA believe those using such tools for -non-personal or commercial use need a license with them:</p> - -<p><blockquote> - -<p>With regard to the Notice to Customers, I would like to begin by -clarifying that the Notice from Section 7.1 of the AVC License -reads:</p> - -<p>THIS PRODUCT IS LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR -THE PERSONAL USE OF A CONSUMER OR OTHER USES IN WHICH IT DOES NOT -RECEIVE REMUNERATION TO (i) ENCODE VIDEO IN COMPLIANCE WITH THE AVC -STANDARD ("AVC VIDEO") AND/OR (ii) DECODE AVC VIDEO THAT WAS ENCODED -BY A CONSUMER ENGAGED IN A PERSONAL ACTIVITY AND/OR WAS OBTAINED FROM -A VIDEO PROVIDER LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED -OR SHALL BE IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE -OBTAINED FROM MPEG LA, L.L.C. SEE HTTP://WWW.MPEGLA.COM</p> - -<p>The Notice to Customers is intended to inform End Users of the -personal usage rights (for example, to watch video content) included -with the product they purchased, and to encourage any party using the -product for commercial purposes to contact MPEG LA in order to become -licensed for such use (for example, when they use an AVC Product to -deliver Title-by-Title, Subscription, Free Television or Internet -Broadcast AVC Video to End Users, or to re-Sell a third party's AVC -Product as their own branded AVC Product).</p> - -<p>Therefore, if a party is to be licensed for its use of an AVC -Product to Sell AVC Video on a Title-by-Title, Subscription, Free -Television or Internet Broadcast basis, that party would need to -conclude the AVC License, even in the case where no royalties were -payable under the License. On the other hand, if that party (either a -Consumer or business customer) simply uses an AVC Product for their -own internal purposes and not for the commercial purposes referenced -above, then such use would be included in the royalty paid for the AVC -Products by the licensed supplier.</p> - -<p>Finally, I note that our AVC License provides worldwide coverage in -countries that have AVC Patent Portfolio Patents, including -Norway.</p> - -<p>I hope this clarification is helpful. If I may be of any further -assistance, just let me know.</p> -</blockquote></p> - -<p>The mentioning of Norwegian patents made me a bit confused, so I -asked for more information:</p> - -<p><blockquote> - -<p>But one minor question at the end. If I understand you correctly, -you state in the quote above that there are patents in the AVC Patent -Portfolio that are valid in Norway. This make me believe I read the -list available from &lt;URL: -<a href="http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx">http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx</a> -&gt; incorrectly, as I believed the "NO" prefix in front of patents -were Norwegian patents, and the only one I could find under Mitsubishi -Electric Corporation expired in 2012. Which patents are you referring -to that are relevant for Norway?</p> - -</blockquote></p> - -<p>Again, the quick answer explained how to read the list of patents -in that list:</p> - -<p><blockquote> - -<p>Your understanding is correct that the last AVC Patent Portfolio -Patent in Norway expired on 21 October 2012. Therefore, where AVC -Video is both made and Sold in Norway after that date, then no -royalties would be payable for such AVC Video under the AVC License. -With that said, our AVC License provides historic coverage for AVC -Products and AVC Video that may have been manufactured or Sold before -the last Norwegian AVC patent expired. I would also like to clarify -that coverage is provided for the country of manufacture and the -country of Sale that has active AVC Patent Portfolio Patents.</p> - -<p>Therefore, if a party offers AVC Products or AVC Video for Sale in -a country with active AVC Patent Portfolio Patents (for example, -Sweden, Denmark, Finland, etc.), then that party would still need -coverage under the AVC License even if such products or video are -initially made in a country without active AVC Patent Portfolio -Patents (for example, Norway). Similarly, a party would need to -conclude the AVC License if they make AVC Products or AVC Video in a -country with active AVC Patent Portfolio Patents, but eventually Sell -such AVC Products or AVC Video in a country without active AVC Patent -Portfolio Patents.</p> -</blockquote></p> - -<p>As far as I understand it, MPEG LA believe anyone using Adobe -Premiere and other video related software with a H.264 distribution -license need a license agreement with MPEG LA to use such tools for -anything non-private or commercial, while it is OK to set up a -Youtube-like service as long as no-one pays to get access to the -content. I still have no clear idea how this applies to Norway, where -none of the patents MPEG LA is licensing are valid. Will the -copyright terms take precedence or can those terms be ignored because -the patents are not valid in Norway?</p> + How does it feel to be wiretapped, when you should be doing the wiretapping... + http://people.skolelinux.org/pere/blog/How_does_it_feel_to_be_wiretapped__when_you_should_be_doing_the_wiretapping___.html + http://people.skolelinux.org/pere/blog/How_does_it_feel_to_be_wiretapped__when_you_should_be_doing_the_wiretapping___.html + Wed, 8 Mar 2017 11:50:00 +0100 + <p>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.

Some channels are very load, others are less loud, and -ads tend to shout very high to get the attention of the viewers, and -the viewers do not like this. This fact is well known to the TV -channels. See for example the BBC white paper -"<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology -for loudness and level dBTP, LU, and all that</a>" from 2011 for a -summary of the problem domain. To better address the need for even -loadness, the TV channels got together several years ago to agree on a -new way to measure loudness in digital files as one step in -standardizing loudness. From this came the ITU-R standard BS.1770, -"<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to -measure audio programme loudness and true-peak audio level</a>".</p> - -<p>The ITU-R BS.1770 specification describe an algorithm to measure -loadness in LUFS (Loudness Units, referenced to Full Scale). But -having a way to measure is not enough. To get the same loudness -across TV channels, one also need to decide which value to standardize -on. For European TV channels, this was done in the EBU Recommondaton -R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness -normalisation and permitted maximum level of audio signals</a>", which -specifies a recommended level of -23 LUFS. In Norway, I have been -told that NRK, TV2, MTG and SBS have decided among themselves to -follow the R128 recommondation for playout from 2016-03-01.</p> - -<p>There are free software available to measure and adjust the loudness -level using the LUFS. In Debian, I am aware of a library named -<a href="https://tracker.debian.org/pkg/libebur128">libebur128</a> -able to measure the loudness and since yesterday morning a new binary -named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a> -capable of both measuring and adjusting was uploaded and is waiting -for NEW processing. I plan to maintain the latter in Debian under the -<a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian -multimedia</a> umbrella.</p> - -<p>The free software based TV channel I am involved in, -<a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the -R128 recommondation ourself as soon as we can adjust the software to -do so, and the bs1770gain tool seem like a good fit for that part of -the puzzle to measure loudness on new video uploaded to Frikanalen. -Personally, I plan to use bs1770gain to adjust the loudness of videos -I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the -NUUG member organisation</a>. The program seem to be able to measure -the LUFS value of any media file handled by ffmpeg, but I've only -successfully adjusted the LUFS value of WAV files. I suspect it -should be able to adjust it for all the formats handled by ffmpeg.</p> + Nasjonalbiblioteket avslutter sin ulovlige bruk av Google Skjemaer + http://people.skolelinux.org/pere/blog/Nasjonalbiblioteket_avslutter_sin_ulovlige_bruk_av_Google_Skjemaer.html + http://people.skolelinux.org/pere/blog/Nasjonalbiblioteket_avslutter_sin_ulovlige_bruk_av_Google_Skjemaer.html + Thu, 12 Jan 2017 09:40:00 +0100 + <p>I dag fikk jeg en skikkelig gladmelding. Bakgrunnen er at før jul +arrangerte Nasjonalbiblioteket +<a href="http://www.nb.no/Bibliotekutvikling/Kunnskapsorganisering/Nasjonalt-verksregister/Seminar-om-verksregister">et +seminar om sitt knakende gode tiltak «verksregister»</a>. Eneste +måten å melde seg på dette seminaret var å sende personopplysninger +til Google via Google Skjemaer. Dette syntes jeg var tvilsom praksis, +da det bør være mulig å delta på seminarer arrangert av det offentlige +uten å måtte dele sine interesser, posisjon og andre +personopplysninger med Google. Jeg ba derfor om innsyn via +<a href="https://www.mimesbronn.no/">Mimes brønn</a> i +<a href="https://www.mimesbronn.no/request/personopplysninger_til_google_sk">avtaler +og vurderinger Nasjonalbiblioteket hadde rundt dette</a>. +Personopplysningsloven legger klare rammer for hva som må være på +plass før en kan be tredjeparter, spesielt i utlandet, behandle +personopplysninger på sine vegne, så det burde eksistere grundig +dokumentasjon før noe slikt kan bli lovlig. To jurister hos +Nasjonalbiblioteket mente først dette var helt i orden, og at Googles +standardavtale kunne brukes som databehandlingsavtale. Det syntes jeg +var merkelig, men har ikke hatt kapasitet til å følge opp saken før +for to dager siden.</p> + +<p>Gladnyheten i dag, som kom etter at jeg tipset Nasjonalbiblioteket +om at Datatilsynet underkjente Googles standardavtaler som +databehandleravtaler i 2011, er at Nasjonalbiblioteket har bestemt seg +for å avslutte bruken av Googles Skjemaer/Apps og gå i dialog med DIFI +for å finne bedre måter å håndtere påmeldinger i tråd med +personopplysningsloven. Det er fantastisk å se at av og til hjelper +det å spørre hva i alle dager det offentlige holder på med.</p> - Hva gjør at NRK kan distribuere H.264-video uten patentavtale med MPEG LA? - http://people.skolelinux.org/pere/blog/Hva_gj_r_at_NRK_kan_distribuere_H_264_video_uten_patentavtale_med_MPEG_LA_.html - http://people.skolelinux.org/pere/blog/Hva_gj_r_at_NRK_kan_distribuere_H_264_video_uten_patentavtale_med_MPEG_LA_.html - Wed, 10 Jun 2015 15:20:00 +0200 - <p>Helt siden jeg i 2012 fikk beskjed fra MPEG LA om at -<a href="http://people.skolelinux.org/pere/blog/MPEG_LA_mener_NRK_m__ha_avtale_med_dem_for___kringkaste_og_publisere_H_264_video.html">NRK -trengte patentavtale med dem</a> hvis de distribuerte H.264-video til -sluttbrukere, har jeg lurt på hva som gjør at NRK ikke har slik -avtale.

Har NRK vurdert om -det er behov for en patentavtale med -<a href="http://www.mpegla.com/">MPEG LA</a> slik det står i -programvarelisensene til blant annet Apple Final Cut Studio, Adobe -Premiere Pro, Avid og Apples Final Cut Pro X?</p> - -<p>Hvis dere har vurdert dette, hva var utfallet av en slik vurdering?</p> - -<p>Hvis dere ikke har vurdert dette, har NRK planer om å vurdere behovet -for patentavtale?</p> -<p>I følge en artikkel på -<a href="https://nrkbeta.no/2012/02/01/siste-kutt-for-final-cut/">NRK -Beta i 2012</a> har NRK brukt eller testet både Apple Final Cut -Studio, Adobe Premiere Pro, Avid og Apples Final Cut Pro X til bruk -for å redigere video før sending. Alle disse har bruksvilkår -understøttet av opphavsretten som sier at de kun kan brukes til å lage -filmer til personlig og ikke-kommersiell bruk - med mindre en har en -lisensavtale med MPEG LA om bruk av patenter utstedt i USA for H.264. -Se f.eks. <a href="http://www.avid.com/static/resources/common/documents/corporate/LICENSE.pdf">bruksvilkårene for Avid</a>, <a href="http://news.cnet.com/8301-30685_3-20000101-264.html">Adobe Premiere</a> og <a href="http://images.apple.com/legal/sla/docs/finalcutstudio2.pdf">Apple Final -Cut Studio</a> og søk etter "MPEG LA".</p> - -<p>Dette får meg til å lure på om det er brudd på opphavsretten å bruke -disse verktøyene i strid med bruksvilkårene uten patentavtale med MPEG -LA. Men NRK bruker jo tilsynelatende disse verktøyene uten patentavtale -med MPEG LA.</p> - -<p>I følge forfatteren av Open Broadcast Encoder finnes det to typer -H.264-relaterte avtaler en kan få med MPEG LA. Det er én for å lage -programvare og utstyr som produserer H.264-video, og en annen for å -kringkaste video som bruker H.264. Dette forteller meg at selv om -produsentene av utstyr og programvare som NRK bruker har en slik avtale -med MPEG LA, så trenges det en egen avtale for å kringkaste video på det -formatet.</p> - -<p>I følge Ryan Rodriguez hos MPEG LA, da jeg spurte ham på epost i -juni 2012, har NRK ikke en slik avtale med MPEG LA. Han sa videre at -NRK trenger en slik avtale hvis NRK tilbyr H.264-kodet video til -sluttbrukere. Jeg sjekket listen med -<a href="http://www.mpegla.com/main/programs/AVC/Pages/Licensees.aspx">organisasjoner -med avtale med MPEG LA</a> og NRK står fortsatt ikke der.</p> - -<p>Jeg lurer dermed på hva som gjør at NRK kan bruke de overnevnte -videoredigeringsverktøyene, som tilsynelatende har krav om avtale med -MPEG LA for å kunne brukes slik NRK bruker dem, til å lage videofiler -for distribusjon uten å ha en avtale med MPEG LA om distribusjon av -H.264-video?

Jeg er blitt spurt hva som er grunnlaget for -<a href="http://people.skolelinux.org/pere/blog/Norwegian_citizens_now_required_by_law_to_give_their_fingerprint_to_the_police.html">min -påstand i forrige bloggpost</a> om at det nå blir krav om å avgi -fingeravtrykk til politiet for å fungere som borger i Norge. De som -spør klarer ikke lese det ut fra det som er vedtatt. Her er en liten -oppsummering om hva jeg baserer det på. Det sies ikke direkte i -hverken proposisjon, innstilling eller vedtak, men fremgår når en ser -på indirekte formuleringer.</p> - -<p>I -<a href="https://www.regjeringen.no/nb/dokumenter/prop.-66-l-2014-2015/id2399703/">stortingsproposisjon -66</a>, avsnitt 6.3.5 (Avgivelse av biometriske personopplysninger) -står det<p> - -<p><blockquote> - - <p>Departementet foreslår at både ansiktsfoto og fingeravtrykk skal - kunne opptas og lagres som identifikasjonsdata i de nasjonale - ID-kortene, på samme måte som i passene. Lovforslaget er derfor - utformet i tråd med passloven § 6 annet ledd, som fastslår at det - til bruk for senere verifisering eller kontroll av passinnehaverens - identitet kan innhentes og lagres i passet biometrisk - personinformasjon i form av ansiktsfoto og fingeravtrykk (to - fingre). Dagens ordning med lagring av ansiktsfoto og fingeravtrykk - i et kontaktløst smartkort i passet er basert på internasjonale - standarder. Fingeravtrykkene i nasjonalt ID-kort vil bli beskyttet - på samme måte som fingeravtrykkene i passene.</p> - - <p>[...]</p> - - <p>For norske forhold understreker departementet at innføring av - nasjonale ID-kort sammen med innføring av nye systemer for sikrere - utstedelse og kontroll av pass og relaterte dokumenter gir mulighet - til å utforme ordningen slik at den best mulig møter utfordringene - forbundet med identitetskriminalitet. Det tilsier at fingeravtrykk - opptas og lagres i alle nasjonale ID-kort.</p> -</blockquote></p> - -<p>Departementet sier altså at sin anbefaling er at fingeravtrykk skal -opptas og lagres i alle nasjonale ID-kort. Det skrives som om det -blir valgfritt, på samme måten som det skrives passloven, der det i -loven sier at det kan -«<a href="https://lovdata.no/dokument/NL/lov/1997-06-19-82#§6">innhentes -og lagres i passet biometrisk personinformasjon i form av ansiktsfoto -og fingeravtrykk (to fingre)</a>». Men på tross av bruken av «kan» i -passloven er det innført krav om å avgi fingeravtrykk for å få et pass -i Norge. Proposisjonen sier i tillegg i del 1 (Proposisjonens -hovedinnhold) at ID-kortene skal være like pålitelig som pass og ha -samme sikkerhetsnivå som pass. Departementet foreslår altså at -ID-kortene skal gis etter samme regler som for pass.</p> - -<p>Formuleringene fra hovedinnholdet i proposisjonen er videreført i -<a href="https://www.stortinget.no/no/Saker-og-publikasjoner/Publikasjoner/Innstillinger/Stortinget/2014-2015/inns-201415-243/?lvl=0">innstillingen -fra stortingskomiteen</a>, der det konkret står «De foreslåtte reglene -vil gi befolkningen tilbud om et offentlig utstedt identitetsbevis som -vil være like pålitelig som passet, og mer praktisk å bruke som -legitimasjon» og «Det nasjonale ID-kortet skal også holde samme -sikkerhetsnivå som passet». Komiteen har altså ingen kommentarer -eller innsigelser til dette forslaget, og gjorde i debatten da saken -ble vedtatt det klart at dette var en god sak og at en enstemmig -komité var glad for resultatet. Stortinget har dermed stilt seg helt -og fullt bak departementets forslag.</p> - -<p>For meg er det åpenbart når en leser proposisjonen at «like -pålitelig» og «samme sikkerhetsnivå» vil bli tolket av departementet -som «med samme biometrisk informasjon som i passene», og departementet -forklarer i tillegg i proposisjonen at de har tenkt at -fingeravtrykkene «vil bli beskyttet på samme måte som fingeravtrykkene -i passene». Jeg ser det dermed som åpenbart at den samme -tvangsinnhentingen av fingeravtrykk som gjelder for pass vil bli -viderført til de nasjonale ID-kortene.</p> - -<p>Det eneste som kan endre dette er massive protester fra -befolkningen på at folk som ikke er mistenkt for noe kriminelt skal -tvinges til å gi fingeravtrykket til politiet for å f.eks. kunne få -bankkonto eller stemme ved valg. Det kunne få departementet til å -snu. Det tror jeg ikke vil skje.</p> + Where did that package go? &mdash; geolocated IP traceroute + http://people.skolelinux.org/pere/blog/Where_did_that_package_go___mdash__geolocated_IP_traceroute.html + http://people.skolelinux.org/pere/blog/Where_did_that_package_go___mdash__geolocated_IP_traceroute.html + Mon, 9 Jan 2017 12:20:00 +0100 + <p>Did you ever wonder where the web trafic really flow to reach the +web servers, and who own the network equipment it is flowing through? +It is possible to get a glimpse of this from using traceroute, but it +is hard to find all the details. Many years ago, I wrote a system to +map the Norwegian Internet (trying to figure out if our plans for a +network game service would get low enough latency, and who we needed +to talk to about setting up game servers close to the users. Back +then I used traceroute output from many locations (I asked my friends +to run a script and send me their traceroute output) to create the +graph and the map. The output from traceroute typically look like +this: + +<p><pre> +traceroute to www.stortinget.no (85.88.67.10), 30 hops max, 60 byte packets + 1 uio-gw10.uio.no (129.240.202.1) 0.447 ms 0.486 ms 0.621 ms + 2 uio-gw8.uio.no (129.240.24.229) 0.467 ms 0.578 ms 0.675 ms + 3 oslo-gw1.uninett.no (128.39.65.17) 0.385 ms 0.373 ms 0.358 ms + 4 te3-1-2.br1.fn3.as2116.net (193.156.90.3) 1.174 ms 1.172 ms 1.153 ms + 5 he16-1-1.cr1.san110.as2116.net (195.0.244.234) 2.627 ms he16-1-1.cr2.oslosda310.as2116.net (195.0.244.48) 3.172 ms he16-1-1.cr1.san110.as2116.net (195.0.244.234) 2.857 ms + 6 ae1.ar8.oslosda310.as2116.net (195.0.242.39) 0.662 ms 0.637 ms ae0.ar8.oslosda310.as2116.net (195.0.242.23) 0.622 ms + 7 89.191.10.146 (89.191.10.146) 0.931 ms 0.917 ms 0.955 ms + 8 * * * + 9 * * * +[...] +</pre></p> + +<p>This show the DNS names and IP addresses of (at least some of the) +network equipment involved in getting the data traffic from me to the +www.stortinget.no server, and how long it took in milliseconds for a +package to reach the equipment and return to me. Three packages are +sent, and some times the packages do not follow the same path. This +is shown for hop 5, where three different IP addresses replied to the +traceroute request.</p> + +<p>There are many ways to measure trace routes. Other good traceroute +implementations I use are traceroute (using ICMP packages) mtr (can do +both ICMP, UDP and TCP) and scapy (python library with ICMP, UDP, TCP +traceroute and a lot of other capabilities). All of them are easily +available in <a href="https://www.debian.org/">Debian</a>.</p> + +<p>This time around, I wanted to know the geographic location of +different route points, to visualize how visiting a web page spread +information about the visit to a lot of servers around the globe. The +background is that a web site today often will ask the browser to get +from many servers the parts (for example HTML, JSON, fonts, +JavaScript, CSS, video) required to display the content. This will +leak information about the visit to those controlling these servers +and anyone able to peek at the data traffic passing by (like your ISP, +the ISPs backbone provider, FRA, GCHQ, NSA and others).</p> + +<p>Lets pick an example, the Norwegian parliament web site +www.stortinget.no. It is read daily by all members of parliament and +their staff, as well as political journalists, activits and many other +citizens of Norway. A visit to the www.stortinget.no web site will +ask your browser to contact 8 other servers: ajax.googleapis.com, +insights.hotjar.com, script.hotjar.com, static.hotjar.com, +stats.g.doubleclick.net, www.google-analytics.com, +www.googletagmanager.com and www.netigate.se. I extracted this by +asking <a href="http://phantomjs.org/">PhantomJS</a> to visit the +Stortinget web page and tell me all the URLs PhantomJS downloaded to +render the page (in HAR format using +<a href="https://github.com/ariya/phantomjs/blob/master/examples/netsniff.js">their +netsniff example</a>. I am very grateful to Gorm for showing me how +to do this). My goal is to visualize network traces to all IP +addresses behind these DNS names, do show where visitors personal +information is spread when visiting the page.</p> + +<p align="center"><a href="www.stortinget.no-geoip.kml"><img +src="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geoip-small.png" alt="map of combined traces for URLs used by www.stortinget.no using GeoIP"/></a></p> + +<p>When I had a look around for options, I could not find any good +free software tools to do this, and decided I needed my own traceroute +wrapper outputting KML based on locations looked up using GeoIP.

I got good help from by NUUG +colleague Anders Einar with this, and the result can be seen in +<a href="https://github.com/petterreinholdtsen/kmltraceroute">my +kmltraceroute git repository</a>. Unfortunately, the quality of the +free GeoIP databases I could find (and the for-pay databases my +friends had access to) is not up to the task. The IP addresses of +central Internet infrastructure would typically be placed near the +controlling companies main office, and not where the router is really +located, as you can see from <a href="www.stortinget.no-geoip.kml">the +KML file I created</a> using the GeoLite City dataset from MaxMind. + +<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg"><img +src="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy-small.png" alt="scapy traceroute graph for URLs used by www.stortinget.no"/></a></p> + +<p>I also had a look at the visual traceroute graph created by +<a href="http://www.secdev.org/projects/scapy/">the scrapy project</a>, +showing IP network ownership (aka AS owner) for the IP address in +question. +<a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg">The +graph display a lot of useful information about the traceroute in SVG +format</a>, and give a good indication on who control the network +equipment involved, but it do not include geolocation.

Its methology of combining guesses based on DNS names, +various location databases and finally use latecy times to rule out +candidate locations seemed to do a very good job of guessing correct +geolocation. But it could only do one trace at the time, did not have +a sensor in Norway and did not make the geolocations easily available +for postprocessing. So I contacted the developer and asked if he +would be willing to share the code (he refused until he had time to +clean it up), but he was interested in providing the geolocations in a +machine readable format, and willing to set up a sensor in Norway. So +since yesterday, it is possible to run traces from Norway in this +service thanks to a sensor node set up by +<a href="https://www.nuug.no/">the NUUG assosiation</a>, and get the +trace in KML format for further processing.</p> + +<p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-kml-join.kml"><img +src="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-kml-join.png" alt="map of combined traces for URLs used by www.stortinget.no using geotraceroute"/></a></p> + +<p>Here we can see a lot of trafic passes Sweden on its way to +Denmark, Germany, Holland and Ireland. Plenty of places where the +Snowden confirmations verified the traffic is read by various actors +without your best interest as their top priority.</p> + +<p>Combining KML files is trivial using a text editor, so I could loop +over all the hosts behind the urls imported by www.stortinget.no and +ask for the KML file from GeoTraceroute, and create a combined KML +file with all the traces (unfortunately only one of the IP addresses +behind the DNS name is traced this time. To get them all, one would +have to request traces using IP number instead of DNS names from +GeoTraceroute). That might be the next step in this project.</p> + +<p>Armed with these tools, I find it a lot easier to figure out where +the IP traffic moves and who control the boxes involved in moving it. +And every time the link crosses for example the Swedish border, we can +be sure Swedish Signal Intelligence (FRA) is listening, as GCHQ do in +Britain and NSA in USA and cables around the globe.
