<citerefentry><refentrytitle>password-request</refentrytitle>
197
<manvolnum>8mandos</manvolnum></citerefentry>. The keys are
198
normally written to /etc/mandos for later installation into the
199
initrd image, but this, like most things, can be changed with
200
command line options.
203
It can also be used to generate ready-made sections for

<citerefentry><refentrytitle>mandos-clients.conf</refentrytitle>
205
<manvolnum>5</manvolnum></citerefentry> using the
