====== APT ======

===== Configuration =====

==== Force IPv4 ====

<code bash>
echo 'Acquire::ForceIPv4 "true";' | sudo tee /etc/apt/apt.conf.d/99force-ipv4
</code>

==== Limit download speed ===
To limit download speed to 250kBytes/s:

<file python /etc/apt/apt.conf.d/75lowerspeed>
Acquire
{
   Queue-mode "access";
   http
   {
      Dl-Limit "250";
   };
};
</file>

==== Use apt-cacher ====
<file | /etc/apt/apt.conf.d/02proxy>
Acquire::http { Proxy "http://192.168.0.231:3142"; };
Acquire::https::proxy "DIRECT";
</file>
or
Replace all mirror hostnames with cachinghost/hostname in sources.list, so
<code>deb http://ftp.uni-kl.de/debian etch main</code>

should now become:
<code>deb http://192.168.0.17:3142/ftp.uni-kl.de/debian etch main</code>
