The file needs to list all clients that should be able to use
86
the service. All clients listed will be regarded as valid, even
87
if a client was declared invalid in a previous run of the
69
the service. The settings in this file can be overridden by
70
runtime changes to the server, which it saves across restarts.
71
(See the section called <quote>PERSISTENT STATE</quote> in
72
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
73
>8</manvolnum></citerefentry>.) However, any <emphasis
74
>changes</emphasis> to this file (including adding and removing
75
clients) will, at startup, override changes done during runtime.

The format starts with a <literal>[<replaceable>section

Unknown options are ignored. The used options are as follows:
124
<term><option>timeout<literal> = </literal><replaceable

128
The timeout is how long the server will wait for a
129
successful checker run until a client is considered
130
invalid - that is, ineligible to get the data this server
131
holds. By default Mandos will use 1 hour.
134
The <replaceable>TIME</replaceable> is specified as a
135
space-separated number of values, each of which is a
136
number and a one-character suffix. The suffix must be one
137
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
138
<quote>h</quote>, and <quote>w</quote> for days, seconds,
139
minutes, hours, and weeks, respectively. The values are
140
added together to give the total time value, so all of
141
<quote><literal>330s</literal></quote>,
142
<quote><literal>110s 110s 110s</literal></quote>, and
143

of five minutes and thirty seconds.

How often to run the checker to confirm that a client is

170
This option allows you to override the default shell

172
still up. Any output of the command will be ignored, only

195
This option is <emphasis>optional</emphasis>.
198
Extended timeout is an added timeout that is given once
199
after a password has been sent successfully to a client.
200
The timeout is by default longer than the normal timeout,
201
and is used for handling the extra long downtime while a
202
machine is booting up. Time to take into consideration
203
when changing this value is file system checks and quota
204
checks. The default value is 15 minutes.

259

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

328
This option is <emphasis>optional</emphasis>.
331
The timeout is how long the server will wait, after a
332
successful checker run, until a client is disabled and not
333
allowed to get the data this server holds. By default
334
Mandos will use 5 minutes. See also the
335
<option>extended_timeout</option> option.
338
The <replaceable>TIME</replaceable> is specified as a
339
space-separated number of values, each of which is a
340
number and a one-character suffix. The suffix must be one
341
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
342
<quote>h</quote>, and <quote>w</quote> for days, seconds,
343
minutes, hours, and weeks, respectively. The values are
