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>Pokročilé</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><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> je jedním z <span class="emphasis"><em>TCP</em></span>
nebo <span class="emphasis"><em>UDP</em></span> - internetový protokol, který je používán
službou.</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="" type="text/javascript" src="main.js"><!----></script><hr xmlns=""/><div xmlns="" class="copyright">© Mageia</div><div xmlns="" class="license"><a
