      <command>&COMMANDNAME;</command> is a client program that
122
141
      communicates with <citerefentry><refentrytitle
123
142
      >mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
124
 
      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.
 
143
      to get a password.  In slightly more detail, this client program
 
144
      brings up network interfaces, uses the interfaces’ IPv6
 
145
      link-local addresses to get network connectivity, uses Zeroconf
 
146
      to find servers on the local network, and communicates with
 
147
      servers using TLS with an OpenPGP key to ensure authenticity and
 
148
      confidentiality.  This client program keeps running, trying all
 
149
      servers on the network, until it receives a satisfactory reply
 
150
      or a TERM signal.  After all servers have been tried, all
 
151
      servers are periodically retried.  If no servers are found it
 
152
      will wait indefinitely for new servers to appear.
 
153
    </para>
 
154
    <para>
 
155
      The network interfaces are selected like this: If any interfaces
 
156
      are specified using the <option>--interface</option> option,
 
157
      those interface are used.  Otherwise,
 
158
      <command>&COMMANDNAME;</command> will use all interfaces that
 
159
      are not loopback interfaces, are not point-to-point interfaces,
 
160
      are capable of broadcasting and do not have the NOARP flag (see
 
161
      <citerefentry><refentrytitle>netdevice</refentrytitle>
 
162
      <manvolnum>7</manvolnum></citerefentry>).  (If the
 
163
      <option>--connect</option> option is used, point-to-point
 
164
      interfaces and non-broadcast interfaces are accepted.)  If any
 
165
      used interfaces are not up and running, they are first taken up
 
166
      (and later taken down again on program exit).
 
167

      Before network interfaces are selected, all <quote>network

            This option is normally only useful for testing and

            debugging.
 
223
            Normally, Zeroconf would be used to locate Mandos servers,

            in which case this option would only be used when testing
 
225
            and debugging.
