<para>
64
The file &CONFPATH; is a configuration file for <citerefentry
65
><refentrytitle>mandos</refentrytitle>
66
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
67
The file needs to list all clients that should be able to use
68
the service. All clients listed will be regarded as enabled,
69
even if a client was disabled in a previous run of the server.
70
</para>

<para>
72
The format starts with a <literal>[<replaceable>section
73
header</replaceable>]</literal> which is either
74
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
75
name</replaceable>]</literal>. The <replaceable>client
76
name</replaceable> can be anything, and is not tied to a host
77
name. Following the section header is any number of
78
<quote><varname><replaceable>option</replaceable
79
></varname>=<replaceable>value</replaceable></quote> entries,
80
with continuations in the style of RFC 822. <quote><varname
81
><replaceable>option</replaceable></varname>: <replaceable
82
>value</replaceable></quote> is also accepted. Note that
83
leading whitespace is removed from values. Values can contain
84
format strings which refer to other values in the same section,
85
or values in the <quote>DEFAULT</quote> section (see <xref
86
linkend="expansion"/>). Lines beginning with <quote>#</quote>

This option allows you to override the default shell

still up. Any output of the command will be ignored, only
167
the exit code is checked: If the exit code of the command
168
is zero, the client is considered up. The command will be
169
run using <quote><command><filename>/bin/sh</filename>

<option>-c</option></command></quote>, so
171
<varname>PATH</varname> will be searched. The default

If present, this option must be set to a string of

OpenPGP encrypted data, decryptable only by the client.

The program <citerefentry><refentrytitle><command

this, if desired.

</para>
285
<para>
286
Note: this value of this option will probably be very
287
long. A useful feature to avoid having unreadably-long
288
lines is that a line beginning with white space adds to
289
the value of the previous line, RFC 822-style.

The timeout is how long the server will wait (for either a
303
successful checker run or a client receiving its secret)
304
until a client is disabled and not allowed to get the data
305
this server holds. By default Mandos will use 5 minutes.

The <replaceable>TIME</replaceable> is specified as a

space-separated number of values, each of which is a

311
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
312
<quote>h</quote>, and <quote>w</quote> for days, seconds,
313
minutes, hours, and weeks, respectively. The values are

added together to give the total time value, so all of
315
<quote><literal>330s</literal></quote>,
316
<quote><literal>110s 110s 110s</literal></quote>, and
317

318

Extended timeout is an added timeout that is given once
332
after a password has been sent sucessfully to a client.
333
The timeout is by default longer than the normal timeout,
334
and is used for handling the extra long downtime while a
335
matchine is booting up. Time to take into consideration
336
when changing this value is system file checks and quota
337
checks. The default value is 15 minutes.
