      <command>&COMMANDNAME;</command> is a mandos plugin that works
 
103
 
      like a client program that through avahi detects mandos servers,
 
104
 
      sets up a gnutls connect and request a encrypted password. Any
 
105
 
      passwords given is automaticly decrypted and passed to
 
 
127
      <command>&COMMANDNAME;</command> is a client program that
 
 
128
      communicates with <citerefentry><refentrytitle
 
 
129
      >mandos</refentrytitle><manvolnum>8</manvolnum></citerefentry>
 
 
130
      to get a password.  It uses IPv6 link-local addresses to get
 
 
131
      network connectivity, Zeroconf to find the server, and TLS with
 
 
132
      an OpenPGP key to ensure authenticity and confidentiality.  It
 
 
133
      keeps running, trying all servers on the network, until it
 
 
134
      receives a satisfactory reply.
 
 
137
      This program is not meant to be run directly; it is really meant
 
 
138
      to run as a plugin of the <application>Mandos</application>

      This program is the client part.  It is a plugin started by
 
 
162
      <citerefentry><refentrytitle>plugin-runner</refentrytitle>
 
 
163
      <manvolnum>8mandos</manvolnum></citerefentry> which will run in
 
 
164
      an initial <acronym>RAM</acronym> disk environment.
 
 
167
      This program could, theoretically, be used as a keyscript in
 
 
168
      <filename>/etc/crypttab</filename>, but it would then be
 
 
169
      impossible to enter the encrypted root disk password at the
 
 
170
      console, since this program does not read from the console at
 
 
171
      all.  This is why a separate plugin does that, which will be run
