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
accessibly from the network. The "<span class="emphasis"><em>Everything (no
firewall)</em></span>" button has a particular role: it 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 checkbuttons are more or less self-explanatory. As an example, you
will check the "CUPS server" button 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 set of checkbuttons only comprises the most common services. The
"Advanced" button allows to enable messages that correspond to a service for
which no checkbutton exists. The "<span class="emphasis"><em>Advanced</em></span>" button
opens a window where you can enable a series of services by typing a list of
couples (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=""
