<command>&COMMANDNAME;</command> is a program to generate the
183
<citerefentry><refentrytitle>mandos-client</refentrytitle>

163
<citerefentry><refentrytitle>password-request</refentrytitle>

<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
185
165
normally written to /etc/mandos for later installation into the
186
initrd image, but this, and most other things, can be changed
187
with command line options.
190
This program can also be used with the
191
<option>--password</option> or <option>--passfile</option>
192
options to generate a ready-made section for
193
<filename>clients.conf</filename> (see

command line options.
