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>Geavanceerd</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>&lt;poort-nummer&gt;/&lt;protocol&gt;</em></span></p><table border="0" summary="Simple list" class="simplelist"><tr><td>- <span class="emphasis"><em>&lt;poort-nummer&gt;</em></span>Is de waarde van
 de poort die is toegewezen aan de dienst die u wilt inschakelen
(bijvoorbeeld 873 voor de RSYNC-service) zoals gedefinieerd in
<span class="emphasis"><em>RFC-433</em></span>;</td></tr><tr><td>- <span class="emphasis"><em>&lt;protocol&gt;</em></span>is één van <span class="emphasis"><em>TCP</em></span> of
<span class="emphasis"><em>UDP</em></span> - Het internetprotocol dat door de dienst wordt
gebruikt.</td></tr></table><p>Bijvoorbeeld, de vermelding voor het verlenen van toegang tot de
RSYNC-dienst is dus <span class="emphasis"><em>873/tcp</em></span>.</p><p>Als een dienst is geïmplementeerd om beide protocollen te gebruiken, dan
specificeert u 2 koppels voor dezelfde poort.</p></div><script xmlns="" type="text/javascript" src="main.js"><!----></script><hr xmlns=""/><div xmlns="" class="copyright">© Mageia</div><div xmlns=""
