    <title>DESCRIPTION</title>

    <para>

      <command>&dhpackage;</command> is the daemon providing a remote

      API for Ganeti clusters.

    </para>

    <para>

      It is automatically started on the master node, and by default

      it uses SSL encryption. This can be disabled by passing the

      <option>--no-ssl</option> option, or alternatively the

      certificate used can be changed via the <option>-C</option>

      option and the key via the <option>-K</option> option.

    </para>

    <para>

      The daemon will listen to the "ganeti-rapi" tcp port, as listed in the

      system services database, or to port 5080 by default.

    </para>

    <para>

      See the <emphasis>Ganeti remote API</emphasis> documentation for

      further information.

    </para>

    <para>

      Requests are logged to

      <filename>@LOCALSTATEDIR@/log/ganeti/rapi-daemon.log</filename>,

      in the same format as for the node and master daemon.

    </para>

  </refsect1>

  <refsect1>

    <title>ACCESS CONTROLS</title>

    <para>

      All query operations are allowed without authentication. Only

      the modification operations require authentication, in the form

      of basic authentication.

    </para>

    <para>

      The users and their rights are defined in a file named

      <filename>rapi_users</filename>, located in the <filename

      class="directory">@LOCALSTATEDIR@/lib/ganeti</filename>

      directory. The users should be listed one per line, in the

      following format:

    </para>

    <screen>username password options</screen>

    <para>

      Currently the <replaceable>options</replaceable> field should

      equal the string <emphasis>write</emphasis> in order to actually

      give write permission for the given users. Example:

    </para>

    <screen>rclient   secret    write

guest   tespw

</screen>

    <para>The first user (<userinput>rclient</userinput>) will have

    read-write rights, whereas the second user does only have read

    (query) rights, and as such is no different than not using

    authentication at all.</para>

    <para>More details (including on how to use hashed passwords) can be found

      in the Ganeti documentation.</para>
