  25       <div class="body"><p>Did you ever wonder where the web trafic really flow to reach the
  26 web servers, and who own the network equipment it is flowing through?
  27 It is possible to get a glimpse of this from using traceroute, but it
  28 is hard to find all the details.  Many years ago, I wrote a system to
  29 map the Norwegian Internet (trying to figure out if our plans for a
  30 network game service would get low enough latency, and who we needed
  31 to talk to about setting up game servers close to the users.  Back
  32 then I used traceroute output from many locations (I asked my friends
  33 to run a script and send me their traceroute output) to create the
  34 graph and the map.  The output from traceroute typically look like
  35 this:

  51 <p>This show the DNS names and IP addresses of (at least some of the)
  52 network equipment involved in getting the data traffic from me to the
  53 www.stortinget.no server, and how long it took in milliseconds for a
  54 package to reach the equipment and return to me.  Three packages are
  55 sent, and some times the packages do not follow the same path.  This
  56 is shown for hop 5, where three different IP addresses replied to the
  57 traceroute request.</p>
  58
  59 <p>There are many ways to measure trace routes.  Other good traceroute
  60 implementations I use are traceroute (using ICMP packages) mtr (can do
  61 both ICMP, UDP and TCP) and scapy (python library with ICMP, UDP, TCP
  62 traceroute and a lot of other capabilities).  All of them are easily
  63 available in <a href="https://www.debian.org/">Debian</a>.</p>
  64
  65 <p>This time around, I wanted to know the geographic location of
  66 different route points, to visualize how visiting a web page spread
  67 information about the visit to a lot of servers around the globe.  The
  68 background is that a web site today often will ask the browser to get
  69 from many servers the parts (for example HTML, JSON, fonts,
  70 JavaScript, CSS, video) required to display the content.  This will
  71 leak information about the visit to those controlling these servers
  72 and anyone able to peek at the data traffic passing by (like your ISP,
  73 the ISPs backbone provider, FRA, GCHQ, NSA and others).</p>
  74
  75 <p>Lets pick an example, the Norwegian parliament web site
  76 www.stortinget.no.  It is read daily by all members of parliament and
  77 their staff, as well as political journalists, activits and many other
  78 citizens of Norway.  A visit to the www.stortinget.no web site will
  79 ask your browser to contact 8 other servers: ajax.googleapis.com,
  80 insights.hotjar.com, script.hotjar.com, static.hotjar.com,
  81 stats.g.doubleclick.net, www.google-analytics.com,
  82 www.googletagmanager.com and www.netigate.se.  I extracted this by
  83 asking <a href="http://phantomjs.org/">PhantomJS</a> to visit the
  84 Stortinget web page and tell me all the URLs PhantomJS downloaded to
  85 render the page (in HAR format using
  86 <a href="https://github.com/ariya/phantomjs/blob/master/examples/netsniff.js">their
  87 netsniff example</a>.  I am very grateful to Gorm for showing me how
  88 to do this).  My goal is to visualize network traces to all IP
  89 addresses behind these DNS names, do show where visitors personal
  90 information is spread when visiting the page.</p>

  94
  95 <p>When I had a look around for options, I could not find any good
  96 free software tools to do this, and decided I needed my own traceroute
  97 wrapper outputting KML based on locations looked up using GeoIP.  KML
  98 is easy to work with and easy to generate, and understood by several
  99 of the GIS tools I have available.  I got good help from by NUUG
 100 colleague Anders Einar with this, and the result can be seen in
 101 <a href="https://github.com/petterreinholdtsen/kmltraceroute">my
 102 kmltraceroute git repository</a>.  Unfortunately, the quality of the
 103 free GeoIP databases I could find (and the for-pay databases my
 104 friends had access to) is not up to the task.  The IP addresses of
 105 central Internet infrastructure would typically be placed near the
 106 controlling companies main office, and not where the router is really
 107 located, as you can see from <a href="www.stortinget.no-geoip.kml">the
 108 KML file I created</a> using the GeoLite City dataset from MaxMind.

 112
 113 <p>I also had a look at the visual traceroute graph created by
 114 <a href="http://www.secdev.org/projects/scapy/">the scrapy project</a>,
 115 showing IP network ownership (aka AS owner) for the IP address in
 116 question.
 117 <a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-scapy.svg">The
 118 graph display a lot of useful information about the traceroute in SVG
 119 format</a>, and give a good indication on who control the network
 120 equipment involved, but it do not include geolocation.  This graph
 121 make it possible to see the information is made available at least for
 122 UNINETT, Catchcom, Stortinget, Nordunet, Google, Amazon, Telia, Level
 123 3 Communications and NetDNA.</p>
 124
 125 <p align="center"><a href="https://geotraceroute.com/index.php?node=4&host=www.stortinget.no"><img
 126 src="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-small.png" alt="example geotraceroute view for www.stortinget.no"/></a></p>
 127
 128 <p>In the process, I came across the
 129 <a href="https://geotraceroute.com/">web service GeoTraceroute</a> by
 130 Salim Gasmi.  Its methology of combining guesses based on DNS names,
 131 various location databases and finally use latecy times to rule out
 132 candidate locations seemed to do a very good job of guessing correct
 133 geolocation.  But it could only do one trace at the time, did not have
 134 a sensor in Norway and did not make the geolocations easily available
 135 for postprocessing.  So I contacted the developer and asked if he
 136 would be willing to share the code (he refused until he had time to
 137 clean it up), but he was interested in providing the geolocations in a
 138 machine readable format, and willing to set up a sensor in Norway.  So
 139 since yesterday, it is possible to run traces from Norway in this
 140 service thanks to a sensor node set up by
 141 <a href="https://www.nuug.no/">the NUUG assosiation</a>, and get the
 142 trace in KML format for further processing.</p>
 143
 144 <p align="center"><a href="http://people.skolelinux.org/pere/blog/images/2017-01-09-www.stortinget.no-geotraceroute-kml-join.kml"><img
 145 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>
 146
 147 <p>Here we can see a lot of trafic passes Sweden on its way to
 148 Denmark, Germany, Holland and Ireland.  Plenty of places where the
 149 Snowden confirmations verified the traffic is read by various actors
 150 without your best interest as their top priority.</p>
 151
 152 <p>Combining KML files is trivial using a text editor, so I could loop
 153 over all the hosts behind the urls imported by www.stortinget.no and
 154 ask for the KML file from GeoTraceroute, and create a combined KML
 155 file with all the traces (unfortunately only one of the IP addresses
 156 behind the DNS name is traced this time.  To get them all, one would
 157 have to request traces using IP number instead of DNS names from
 158 GeoTraceroute).  That might be the next step in this project.</p>
 159
 160 <p>Armed with these tools, I find it a lot easier to figure out where
 161 the IP traffic moves and who control the boxes involved in moving it.
 162 And every time the link crosses for example the Swedish border, we can
 163 be sure Swedish Signal Intelligence (FRA) is listening, as GCHQ do in
 164 Britain and NSA in USA and cables around the globe.  (Hm, what should
 165 we tell them? :) Keep that in mind if you ever send anything
 166 unencrypted over the Internet.</p>
 167
 168 <p>PS: KML files are drawn using
 169 <a href="http://ivanrublev.me/kml/">the KML viewer from Ivan
 170 Rublev<a/>, as it was less cluttered than the local Linux application
 171 Marble.  There are heaps of other options too.</p>
