121
      <command>&COMMANDNAME;</command> is a client program that
140
122
      communicates with <citerefentry><refentrytitle
141
123
      >mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
142
 
      to get a password.  In slightly more detail, this client program
143
 
      brings up network interfaces, uses the interfaces’ IPv6
144
 
      link-local addresses to get network connectivity, uses Zeroconf
145
 
      to find servers on the local network, and communicates with
146
 
      servers using TLS with an OpenPGP key to ensure authenticity and
147
 
      confidentiality.  This client program keeps running, trying all
148
 
      servers on the network, until it receives a satisfactory reply
149
 
      or a TERM signal.  After all servers have been tried, all
150
 
      servers are periodically retried.  If no servers are found it
151
 
      will wait indefinitely for new servers to appear.
152
 
    </para>
153
 
    <para>
154
 
      The network interfaces are selected like this: If any interfaces
155
 
      are specified using the <option>--interface</option> option,
156
 
      those interface are used.  Otherwise,
157
 
      <command>&COMMANDNAME;</command> will use all interfaces that
158
 
      are not loopback interfaces, are not point-to-point interfaces,
159
 
      are capable of broadcasting and do not have the NOARP flag (see
160
 
      <citerefentry><refentrytitle>netdevice</refentrytitle>
161
 
      <manvolnum>7</manvolnum></citerefentry>).  (If the
162
 
      <option>--connect</option> option is used, point-to-point
163
 
      interfaces and non-broadcast interfaces are accepted.)  If any
164
 
      used interfaces are not up and running, they are first taken up
165
 
      (and later taken down again on program exit).

      Before network interfaces are selected, all <quote>network

      to get a password.  It uses IPv6 link-local addresses to get
 
125
      network connectivity, Zeroconf to find servers, and TLS with an
 
126
      OpenPGP key to ensure authenticity and confidentiality.  It
 
127
      keeps running, trying all servers on the network, until it
 
128
      receives a satisfactory reply or a TERM signal is received.

252
 
            can normally not be a pseudo-interface such as

            <quote>br0</quote> or <quote>tun0</quote>; such interfaces
254
 
            will not exist until much later in the boot process, and
255
 
            can not be used by this program, unless created by a
