  <title/>

  <para id="interface">

    If this is specified, the server will only announce the service

    and listen to requests on the specified network interface.

    Default is to use all available interfaces.  <emphasis

    >Note:</emphasis> a failure to bind to the specified

    interface is not considered critical, and the server will not

    exit, but instead continue normally.

  </para>

  <para id="address">

    If this option is used, the server will only listen to the

    specified IPv6 address.  If a link-local address is specified, an

    interface should be set, since a link-local address is only valid

    on a single interface.  By default, the server will listen to all

    available addresses.  If set, this must normally be an IPv6

    address; an IPv4 address can only be specified using IPv4-mapped

    IPv6 address syntax: <quote><systemitem class="ipaddress"

    >::FFFF:192.0.2.3</systemitem ></quote>.  (Only if IPv6 usage is

    <emphasis>disabled</emphasis> (see below) must this be an IPv4

    address.)

  </para>

  <para id="port">

    If this option is used, the server will bind to that port. By

    default, the server will listen to an arbitrary port given by the

    operating system.

  </para>

  <para id="debug">

    If the server is run in debug mode, it will run in the foreground

    and print a lot of debugging information.  The default is to

    <emphasis>not</emphasis> run in debug mode.

  </para>

  <para id="priority_compat">

    GnuTLS priority string for the <acronym>TLS</acronym> handshake.

    The default is <quote><literal

    >SECURE256:!CTYPE-X.509:+CTYPE-OPENPGP:+SIGN-RSA-SHA224:</literal>

    <literal>+SIGN-RSA-RMD160</literal></quote>.

    See <citerefentry><refentrytitle

    >gnutls_priority_init</refentrytitle>

    <manvolnum>3</manvolnum></citerefentry> for the syntax.

    <emphasis>Warning</emphasis>: changing this may make the

    <acronym>TLS</acronym> handshake fail, making server-client

    communication impossible.

  </para>

  <para id="priority">

    GnuTLS priority string for the <acronym>TLS</acronym> handshake.

    The default is <quote><literal

    >SECURE256:!CTYPE-X.509:+CTYPE-OPENPGP</literal></quote>.  See

    <citerefentry><refentrytitle >gnutls_priority_init</refentrytitle>

    <manvolnum>3</manvolnum></citerefentry> for the syntax.

    <emphasis>Warning</emphasis>: changing this may make the

    <acronym>TLS</acronym> handshake fail, making server-client

    communication impossible.

  </para>

  <para id="servicename">

    Zeroconf service name.  The default is

    <quote><literal>Mandos</literal></quote>.  This only needs to be

    changed if for some reason is would be necessary to run more than

    one server on the same <emphasis>host</emphasis>.  This would not

    normally be useful.  If there are name collisions on the same

    <emphasis>network</emphasis>, the newer server will automatically

    rename itself to <quote><literal>Mandos #2</literal></quote>, and

    so on; therefore, this option is not needed in that case.

  </para>

  <para id="dbus">

    This option controls whether the server will provide a D-Bus

    system bus interface.  The default is to provide such an

    interface.

  </para>

  <para id="ipv6">

    This option controls whether the server will use IPv6 sockets and

    addresses.  The default is to use IPv6.  This option should

    <emphasis>never</emphasis> normally be turned off, <emphasis>even in

    IPv4-only environments</emphasis>.  This is because <citerefentry>

    <refentrytitle>mandos-client</refentrytitle>

    <manvolnum>8mandos</manvolnum></citerefentry> will normally use

    IPv6 link-local addresses, and will not be able to find or connect

    to the server if this option is turned off.  <emphasis>Only

    advanced users should consider changing this option</emphasis>.

  </para>

  <para id="restore">

    This option controls whether the server will restore its state

    from the last time it ran.  Default is to restore last state.

  </para>

  <para id="statedir">

    Directory to save (and restore) state in.  Default is

    <quote><filename

    class="directory">/var/lib/mandos</filename></quote>.

  </para>

  <para id="socket">

    If this option is used, the server will not create a new network

    socket, but will instead use the supplied file descriptor.  By

    default, the server will create a new network socket.

  </para>

  <para id="foreground">

    This option will make the server run in the foreground and not

    write a PID file.  The default is to <emphasis>not</emphasis> run

    in the foreground, except in <option>debug</option> mode, which

    implies this option.

  </para>
