determine which type of message from the Internet will be accepted by the
target system. This, in turn, allows the corresponding services on the
system to be accessible from the Internet.</p><p>In the default setting (no button is checked), no service of the system is
accessible from the network. The <span class="emphasis"><em>Everything (no
firewall)</em></span> option enables access to all services of the machine -
an option that does not make much sense in the context of the installer
since it would create a totally unprotected system. Its veritable use is in
the context of the Mageia Control Center (which uses the same GUI layout)
for temporarily disabling the entire set of firewall rules for testing and
debugging purposes.</p><p>All other options are more or less self-explanatory. As an example, you will
enable the CUPS server if you want printers on your machine to be accessible
from the network.</p><p><span class="bold"><strong>Advanced</strong></span></p><p>The <span class="emphasis"><em>Advanced</em></span> option opens a window where you can enable
a series of services by typing a list of <span class="quote">“<span class="quote">couples</span>”</span> (blank
separated)</p><p><span class="emphasis"><em><port-number>/<protocol></em></span></p><table border="0" summary="Simple list" class="simplelist"><tr><td>- <span class="emphasis"><em><port-number></em></span> is the value of the port assigned to
the service you want to enable (e.g. 873 for the RSYNC service) as defined
in <span class="emphasis"><em>RFC-433</em></span>;</td></tr><tr><td>- <span class="emphasis"><em><protocol></em></span> is one of <span class="emphasis"><em>TCP</em></span> or
<span class="emphasis"><em>UDP</em></span> - the internet protocol that is used by the
service.</td></tr></table><p>For instance, the entry for enabling access to the RSYNC service therefore
is <span class="emphasis"><em>873/tcp</em></span>.</p><p>In case a service is implemented to use both protocols, you specify 2
couples for the same port.</p></div><script xmlns="" xmlns:l="http://docbook.sourceforge.net/xmlns/l10n/1.0" src="main.js" type="text/javascript"><!----></script><hr xmlns=""
