<title>DESCRIPTION</title>

<para>
63
The file &CONFPATH; is a configuration file for <citerefentry
64
><refentrytitle>mandos</refentrytitle>
65
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
66
The file needs to list all clients that should be able to use
67
the service. All clients listed will be regarded as enabled,
68
even if a client was disabled in a previous run of the server.
69
</para>
70
<para>
71
The format starts with a <literal>[<replaceable>section
72
header</replaceable>]</literal> which is either
73
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
74
name</replaceable>]</literal>. The <replaceable>client
75
name</replaceable> can be anything, and is not tied to a host
76
name. Following the section header is any number of
77
<quote><varname><replaceable>option</replaceable
78
></varname>=<replaceable>value</replaceable></quote> entries,
79
with continuations in the style of RFC 822. <quote><varname
80
><replaceable>option</replaceable></varname>: <replaceable
81
>value</replaceable></quote> is also accepted. Note that
82
leading whitespace is removed from values. Values can contain
83
format strings which refer to other values in the same section,
84
or values in the <quote>DEFAULT</quote> section (see <xref
85
linkend="expansion"/>). Lines beginning with <quote>#</quote>
86
or <quote>;</quote> are ignored and may be used to provide
87

This option allows you to override the default shell
164
command that the server will use to check if the client is
165
still up. Any output of the command will be ignored, only
166
the exit code is checked: If the exit code of the command
167
is zero, the client is considered up. The command will be
168
run using <quote><command><filename>/bin/sh</filename>
169
<option>-c</option></command></quote>, so
170
<varname>PATH</varname> will be searched. The default

If present, this option must be set to a string of
274
base64-encoded binary data. It will be decoded and sent
275
to the client matching the above
276
<option>fingerprint</option>. This should, of course, be
277
OpenPGP encrypted data, decryptable only by the client.
278
The program <citerefentry><refentrytitle><command
279
>mandos-keygen</command></refentrytitle><manvolnum
280
>8</manvolnum></citerefentry> can, using its
281
<option>--password</option> option, be used to generate
282
this, if desired.
283
</para>
284
<para>
285
Note: this value of this option will probably be very
286
long. A useful feature to avoid having unreadably-long
287
lines is that a line beginning with white space adds to
288
the value of the previous line, RFC 822-style.

The timeout is how long the server will wait (for either a
302
successful checker run or a client receiving its secret)
303
until a client is disabled and not allowed to get the data
304
this server holds. By default Mandos will use 1 hour.
305
</para>
306
<para>
307
The <replaceable>TIME</replaceable> is specified as a
308
space-separated number of values, each of which is a
309
number and a one-character suffix. The suffix must be one
310
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
311
<quote>h</quote>, and <quote>w</quote> for days, seconds,
312
minutes, hours, and weeks, respectively. The values are
313
added together to give the total time value, so all of
314
<quote><literal>330s</literal></quote>,
315
<quote><literal>110s 110s 110s</literal></quote>, and
316
<quote><literal>5m 30s</literal></quote> will give a value
317
of five minutes and thirty seconds.
