    <para>Each network interface of a Mageia system is initially configured with a fix
set of parameters. This corresponds to what is expected by a user of a
desktop computer, but may not be adequate when the system is moved between
various network environments: having the system run in different network
environments will require that multiple configurations co-exist for a given
network device - otherwise the interface might need to be re-configured each
time the network environment changes.</para>

      <para>Linux provides support for multiple configurations of network devices as a
standard feature. The notion of a <emphasis role='bold'>"network
profile"</emphasis> refers to a set of configurations of network devices,
defined for a specific network environment. Each network profile has a
<emphasis role='bold'>name</emphasis> - the initial configuration that comes
out of system generation has the name <emphasis>"default"</emphasis>; when a
new profile is created, a name must be specified which is different from all
already existing profile names.</para>

      <title>Draknetprofile</title>

      <para>Draknetprofile is a - very simple - component of the Mageia Control Center
(MCC), it provides a Graphical User Interface (GUI) for managing
profiles. This GUI allows to

        <itemizedlist>

          <listitem>
            <para>switch between profiles - i.e. activate a target profile to become the
"current profile",</para>

      <para>Defining/modifying profiles concerns the entire Linux system and all its
users. Running draknetprofile therefore requires root privileges. Normally,
launching is achieved from within MCC (which already runs as root):</para>

      <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>

      <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>

      <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>

        <listitem>
          <para>avsluta Draknetprofile (tryck på avsluta-knappen),</para>

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>

      <title>Använda ett system som har mer än en profil</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'>

          </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>
