<command>&COMMANDNAME;</command> is a program to generate the
177
<citerefentry><refentrytitle>mandos-client</refentrytitle>

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

<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
179
165
normally written to /etc/mandos for later installation into the
180
initrd image, but this, and most other things, can be changed
181
with command line options.
184
This program can also be used with the
185
<option>--password</option> or <option>--passfile</option>
186
options to generate a ready-made section for
187
<filename>clients.conf</filename> (see

command line options.
