<command>&COMMANDNAME;</command> is a program to generate the
162
<citerefentry><refentrytitle>mandos-client</refentrytitle>

<manvolnum>8mandos</manvolnum></citerefentry>. The key is
163
<citerefentry><refentrytitle>password-request</refentrytitle>
164
<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
164
165
normally written to /etc/mandos for later installation into the
165
initrd image, but this, and most other things, can be changed
166
with command line options.
169
This program can also be used with the
170
<option>--password</option> option to generate a ready-made
171
section for <filename>clients.conf</filename> (see
172
<citerefentry><refentrytitle>mandos-clients.conf</refentrytitle>
173
<manvolnum>5</manvolnum></citerefentry>).

command line options.
