<div class="section" id="installation-free">
<h1>Installation-free</h1>
<p>In order to provide installation-free package, we provide binary executables
for Linux (32 and 64bits), Windows, and Mac OS X.
The binaries files were generated with <a class="reference external" href="http://www.pyinstaller.org/">Pyinstaller</a> (version 1.5RC1).</p>
<p>If you have Python installed, you can directly run the start_crawl.py script at
root or the pytomo script in bin directory.</p>
<p>If you have Python installed and the RRDtool and webpy python bindings, you can
directly run the 'start_server.py' script at root - you need to specify a port
on which to start the server and then connect to that port on the respective
host from your favourite browser. For example, you start the graphical web
interface on port 5555:<br/>
&emsp $ ./start_server.py 5555<br/>
You will then connect on the respective machine (you need to know its IP and
make sure it allows external connections, otherwise you will only be able to
see the graphs locally on that machine):<br/>
&emsp http://127.0.0.1:5555/ &emsp &emsp &emsp <= visualisation on local machine<br/>
&emsp http://10.193.224.73:5555/ &emsp &emsp <= visualisation from remote host<br/>
By default, the graphs are collected with information from the latest database
in the default database directory. If a new live crawl is started, it is
recommened to stop and start again the graphical web interface and refresh the
page from your browser.</p>
</div>
<div class="section" id="external-resources">
<h1>External Resources</h1>
<p>We based the lib_youtube_download on <a class="reference external" href="http://rg3.github.com/youtube-dl/">YouTube Download</a> script: we simplified
it at most and include only the classes we needed (and only YouTube video
retrieval).</p>
<p>The dns module is taken from the <a class="reference external" href="http://pypi.python.org/pypi/dnspython">DNS Python Package</a>: we just modified rdata
so that <a class="reference external" href="http://www.pyinstaller.org/">Pyinstaller</a> include all needed modules.</p>
<p>The extraction of metadata out of video files is an adaptation of <a class="reference external" href="http://packages.debian.org/sid/python-kaa-metadata">Kaa Metadata
Python Package</a>: it has been modified in order to be independent of Kaa-base
(thus pure Python and portable).</p>
<p>The graphical web interface requires the following external resources, that we
recommend you to install from the repository of your OS distribution: <br/>
a) <a class="reference external" href="http://oss.oetiker.ch/rrdtool/download.en.html">RRDtool python binding</a> <br/>
- For Debian based OS: <br/>
 &emsp sudo apt-get install python-rrdtool <br/>
- For RHEL based OS: <br/>
 &emsp yum install python-rrdtool <br/>
b) <a class="reference external" href="http://webpy.org/download">webpy</a> <br/>
- For Debian based OS: <br/>
 &emsp sudo apt-get install python-webpy <br/>
- For RHEL based OS: <br/>
 &emsp yum install python-webpy
