  24       <div class="date">15th January 2016</div>
  25       <div class="body"><p>During his DebConf15 keynote, Jacob Appelbaum
  26 <a href="https://summit.debconf.org/debconf15/meeting/331/what-is-to-be-done/">observed
  27 that those listening on the Internet lines would have good reason to
  28 believe a computer have a given security hole</a> if it download a
  29 security fix from a Debian mirror.  This is a good reason to always
  30 use encrypted connections to the Debian mirror, to make sure those
  31 listening do not know which IP address to attack.  In August, Richard
  32 Hartmann observed that encryption was not enough, when it was possible
  33 to interfere download size to security patches or the fact that
  34 download took place shortly after a security fix was released, and
  35 <a href="http://richardhartmann.de/blog/posts/2015/08/24-Tor-enabled_Debian_mirror/">proposed
  36 to always use Tor to download packages from the Debian mirror</a>.  He
  37 was not the first to propose this, as the
  38 <tt><a href="https://tracker.debian.org/pkg/apt-transport-tor">apt-transport-tor</a></tt>
  39 package by Tim Retout already existed to make it easy to convince apt
  40 to use <a href="https://www.torproject.org/">Tor</a>, but I was not
  41 aware of that package when I read the blog post from Richard.</p>
  42
  43 <p>Richard discussed the idea with Peter Palfrader, one of the Debian
  44 sysadmins, and he set up a Tor hidden service on one of the central
  45 Debian mirrors using the address vwakviie2ienjx6t.onion, thus making
  46 it possible to download packages directly between two tor nodes,
  47 making sure the network traffic always were encrypted.</p>
  48
  49 <p>Here is a short recipe for enabling this on your machine, by
  50 installing <tt>apt-transport-tor</tt> and replacing http and https
  51 urls with tor+http and tor+https, and using the hidden service instead
  52 of the official Debian mirror site.  I recommend installing
  53 <tt>etckeeper</tt> before you start to have a history of the changes
  54 done in /etc/.</p>
  55
  56 <blockquote><pre>
  57 apt install apt-transport-tor
  58 sed -i 's% http://ftp.debian.org/% tor+http://vwakviie2ienjx6t.onion/%' /etc/apt/sources.list
  59 sed -i 's% http% tor+http%' /etc/apt/sources.list
  60 </pre></blockquote>
  61
  62 <p>If you have more sources listed in /etc/apt/sources.list.d/, run
  63 the sed commands for these too.  The sed command is assuming your are
  64 using the ftp.debian.org Debian mirror.  Adjust the command (or just
  65 edit the file manually) to match your mirror.</p>
  66
  67 <p>This work in Debian Jessie and later.  Note that tools like
  68 <tt>apt-file</tt> only recently started using the apt transport
  69 system, and do not work with these tor+http URLs.  For
  70 <tt>apt-file</tt> you need the version currently in experimental,
  71 which need a recent apt version currently only in unstable.  So if you
  72 need a working <tt>apt-file</tt>, this is not for you.</p>
  73
  74 <p>Another advantage from this change is that your machine will start
  75 using Tor regularly and at fairly random intervals (every time you
  76 update the package lists or upgrade or install a new package), thus
  77 masking other Tor traffic done from the same machine.  Using Tor will
  78 become normal for the machine in question.</p>
  79
  80 <p>On <a href="https://wiki.debian.org/FreedomBox">Freedombox</a>, APT
  81 is set up by default to use <tt>apt-transport-tor</tt> when Tor is
  82 enabled.  It would be great if it was the default on any Debian
  83 system.</p>
