<para>
70
The file &CONFPATH; is a configuration file for <citerefentry
71
><refentrytitle>mandos</refentrytitle>
72
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
73
The file needs to list all clients that should be able to use
74
the service. The settings in this file can be overridden by
75
runtime changes to the server, which it saves across restarts.
76
(See the section called <quote>PERSISTENT STATE</quote> in
77
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
78
>8</manvolnum></citerefentry>.) However, any <emphasis
79
>changes</emphasis> to this file (including adding and removing
80
clients) will, at startup, override changes done during runtime.

The format starts with a <literal>[<replaceable>section
84
header</replaceable>]</literal> which is either
85
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
86
name</replaceable>]</literal>. The <replaceable>client
87
name</replaceable> can be anything, and is not tied to a host
88
name. Following the section header is any number of
89
<quote><varname><replaceable>option</replaceable
90
></varname>=<replaceable>value</replaceable></quote> entries,
91
with continuations in the style of RFC 822. <quote><varname
92
><replaceable>option</replaceable></varname>: <replaceable
93
>value</replaceable></quote> is also accepted. Note that
94
leading whitespace is removed from values. Values can contain
95
format strings which refer to other values in the same section,
96
or values in the <quote>DEFAULT</quote> section (see <xref
97
linkend="expansion"/>). Lines beginning with <quote>#</quote>

This option overrides the default shell command that the
176
server will use to check if the client is still up. Any
177
output of the command will be ignored, only the exit code
178
is checked: If the exit code of the command is zero, the
179
client is considered up. The command will be run using
180
<quote><command><filename>/bin/sh</filename>
181
<option>-c</option></command></quote>, so
182
<varname>PATH</varname> will be searched. The default
183
value for the checker command is <quote><literal
184
><command>fping</command> <option>-q</option> <option
185
>--</option> %%(host)s</literal></quote>. Note that
186
<command>mandos-keygen</command>, when generating output
187
to be inserted into this file, normally looks for an SSH
188
server on the Mandos client, and, if it find one, outputs
189
a <option>checker</option> option to check for the
190
client’s key fingerprint – this is more secure against
191
spoofing.

Extended timeout is an added timeout that is given once
210
after a password has been sent successfully to a client.
211
The timeout is by default longer than the normal timeout,
212
and is used for handling the extra long downtime while a
213
machine is booting up. Time to take into consideration
214
when changing this value is file system checks and quota
215
checks. The default value is 15 minutes.

If present, this option must be set to a string of
315
base64-encoded binary data. It will be decoded and sent
316
to the client matching the above
317
<option>fingerprint</option>. This should, of course, be
318
OpenPGP encrypted data, decryptable only by the client.
319
The program <citerefentry><refentrytitle><command
320
>mandos-keygen</command></refentrytitle><manvolnum
321

this, if desired.
324
</para>
325
<para>
326
Note: this value of this option will probably be very
327
long. A useful feature to avoid having unreadably-long
328
lines is that a line beginning with white space adds to
329
the value of the previous line, RFC 822-style.

The timeout is how long the server will wait, after a
