<title>简介</title>
<para>Mageia
会用默认参数自动配置系统中的每个网络接口。这对于大多数台式机用户来说已经足够，但可能不适用于需要频繁变换网络环境的机器。如果您需要在不同网络环境中使用电脑，则需要为网络设备保存多个配置，否则每当网络环境变更时您都得重新手动配置。</para>
<section>
<title>配置文件</title>
<para>Linux 默认为网络设备提供多配置支持。术语<emphasis
role='bold'>“网络配置”</emphasis>指一系列用于在特定网络环境中使用网络设备的配置。每个网络配置都包括一个<emphasis
role='bold'>名称</emphasis>（由系统生成的初始名称一般为<emphasis>“默认”</emphasis>）；当您创建新的配置时，必须为它指定一个与其他配置不同的名称。</para>
</section>
<section>
<title>Draknetprofile</title>
<para>Draknetprofile 是Mageia 控制中心（MCC）中用于管理网络配置的简易模块。它可以：
<itemizedlist>
<listitem>
<para>切换网络配置：您可以启用某个配置并将其应用到对应的设备；</para>
</listitem>
<listitem>
<para>创建新的配置；</para>

<listitem>
<para>删除现有配置。</para>

<title>运行 Draknetprofile</title>

<title>添加与切换配置</title>
<para>添加/切换配置的操作会影响到Linux系统中的所有用户。因此，您需要root权限来运行Draknetprofile。一般情况下，只需从Mageia控制中心（本身拥有root权限）中启动它即可。</para>

</orderedlist>
<para>Draknetprofile can also be launched by a command-line instruction from a
terminal emulator with root privileges (this may be helpful when
standard-output or error-output from draknetprofile needs to be consulted -
for instance for debugging). Simply type:</para>
<informaltable frame='all' colsep='1' rowsep='1'>

</tbody>
</tgroup>
</informaltable>
<para>After the launch, the main page of Draknetprofile will be displayed:</para>

<caption>
<para><emphasis role='bold'>Figure 2: Management actions of
Draknetprofile</emphasis></para>
</caption>
</mediaobject>
<para>The upper zone of the window contains the list of the names of all presently
defined profiles. The bottom zone presents a series of buttons:</para>
<itemizedlist>
<listitem>
<para>"Activate" ... establish the selected profile (top zone of the window) as
the current profile (and save the properties of the old profile);</para>
</listitem>
<listitem>
<para>"New" ... create a new profile;</para>
</listitem>
<listitem>
<para>"Delete" ... delete the selected profile from the list of defined profiles;</para>
</listitem>
<listitem>
<para>"Quit" ... exit from Draknetprofile.</para>
</listitem>
</itemizedlist>
<para>Before hitting the "Activate" or the "Delete" button, you have to select a
profile from the list: select it by a left-button click on the name of the
target profile.</para>
<para>Hitting the "New" button will launch an auxiliary window where you can type
the name of the profile you want to create; this name must be different from
any already existing profile. This profile will be created as a precise copy
of the currently active profile and immediately activated as the current
profile. You will probably then need to specify its properties (modify the
automatically created configuration) in a second, independent action:</para>
<itemizedlist>
<listitem>
<para>exit from Draknetprofile (hit the "Quit" button),</para>
</listitem>
<listitem>
<para>back in the "Network & Internet" tab, you select the tab "Set up a new
network interface (...)" (marked with dashed red contour in Figure 1),</para>
</listitem>
<listitem>
<para>you then go through the steps for configuring the interface; they are
similar to those you did for configuring the original interface during
system generation - as documented in the <link
linkend='drakconnect-ti1'>Drakconnect manual</link>.</para>
</listitem>
</itemizedlist>
<para>The middle zone of the window is normally hidden, hit the "Advanced" button
to make it visible. It should display the list of names of Draknetprofile
<emphasis role='bold'>"modules"</emphasis> (such as "network", "firewall",
"urpmi"), each with a check-button next to the name; these check-buttons
determine whether the properties controlled by that module are included into
the profile or not.</para>
</section>
<section>
<title>Using a system that has more than one profile</title>
<para>In a system where several profiles are defined, an additional user
interaction is required when the system boots: at the very end of the
bootstrapping activities - just before the Desktop Environment starts - you
will get a message like</para>
<informaltable frame='all' colsep='1' rowsep='1'>
<tgroup cols='1'>
<?dbhtml cellpadding='4' ?>
<tbody>
<row><?dbhtml bgcolor='#DDDDDD' ?><?dbfo bgcolor='#DDDDDD' ?>
<entry><literal> Select network profile: (1) default (2)
roaming* </literal></entry>
</row>
</tbody>
</tgroup>
</informaltable>
<para>Type 1 or 2 to select the "default", respectively the "roaming" profile, or
carriage-return to select the profile that is marked with an asterisk (the
profile that was active when the system had been shut down).</para>
<para>Presently (Mageia-5) there appears to be an intermittent problem: it happens
that the system becomes unresponsive after soliciting the user to select a
profile. The only way out of this situation is to launch another boot. This
problem is under investigation.</para>
</section>
</section>
<section>
<title>Appendix: Files relevant to Draknetprofile</title>
<para>The configuration data of network interfaces are stored in the directory
<emphasis>/etc/sysconfig/network-scripts/</emphasis>, in files with names
like <emphasis>ifcfg-xxx</emphasis>.</para>
<para>The name of the currently active profile is maintained in the file
<emphasis>/etc/netprofile/current</emphasis> .
</para>
