<para>Deze tool<footnote>
<para>U kunt deze tool op de commandoregel starten, door als root <emphasis
role="bold">drakguard</emphasis> te typen.</para>
</footnote> bevindt zich in het
Mageia-configuratiecentrum, in het Beveiligingstabblad, en heet
<guilabel>Controle voor ouders</guilabel>. Indien u deze niet heeft,
installeer dan het drakguard-pakket (dat niet standaard geïnstalleerd is).</para>

<title>Presentation</title>
<para>Drakguard is an easy way to set up parental controls on your computer to
restrict who can do what, and at which times of day. Drakguard has three
useful capabilities:</para>
<itemizedlist>
<listitem>
<para>It restricts web access to named users to set times of day. It does this by
controlling the shorewall firewall built into Mageia.</para>
</listitem>
<listitem>
<para>It blocks execution of particular commands by named users so these users can
only execute what you accept them to execute.</para>
</listitem>
<listitem>
<para>It restricts access to websites, both manually defined through
blacklists/whitelists, but also dynamically based on the content of the
website. To achieve this Drakguard uses the leading opensource parental
control blocker DansGuardian.</para>

<title>Configuring Parental controls</title>
<para><warning>
<para>If your computer contains hard drive partitions that are formatted in Ext2,
Ext3, or ReiserFS format you will see a pop up offering to configure ACL on
your partitions. ACL stands for Access Control Lists, and is a Linux kernel
feature that allows access to individual files to be restricted to named
users. ACL is built into Ext4 and Btrfs file systems, but must be enabled by
an option in Ext2, Ext3, or Reiserfs partitions. If you select 'Yes' to this
prompt drakguard will configure all your partitions to support ACL, and will
then suggest you reboot.</para>
</warning><guibutton>Enable parental control</guibutton>: If checked, the parental
control is enabled and the access to <guilabel>Block programs</guilabel> tab
is opened.</para>
<para><guibutton>Block all network traffic</guibutton>: If checked, all the
websites are blocked, except the ones in the whitelist tab. Otherwise, all
the websites are allowed, except the ones in the blacklist tab.</para>
<para><guibutton>User access</guibutton>: Users on the left hand side will have
their access restricted according to the rules you define. Users on the
right hand side have unrestricted access so adult users of the computer are
not inconvenienced. Select a user in the left hand side and click on
<guibutton>Add</guibutton> to add him/her as an allowed user. Select an
user in the right hand side and click on <guibutton>Remove</guibutton> to
remove him/her from the allowed users.</para>
<para><guibutton>Time control:</guibutton> If checked, internet access is allowed
with restrictions between the <guilabel>Start</guilabel> time and
<guilabel>End</guilabel> time. It is totally blocked outside these time
window.</para>
<section>
<title>Blacklist/Whitelist tab</title>
<para>Enter the website URL in the first field at the top and click on the
<guibutton>Add</guibutton> button.</para>
</section>
<section>
<title>Block Programs Tab</title>
<para><guibutton>Block Defined Applications</guibutton>: Enables the use of ACL to
restrict access to specific applications. Insert the path to the
applications you wish to block.</para>
<para><guibutton>Unblock Users list</guibutton>: Users listed on the right hand
side will not be subject to acl blocking.</para>
