The file needs to list all clients that should be able to use
66
the service. All clients listed will be regarded as valid, even
67
if a client was declared invalid in a previous run of the
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
104
<term><option>timeout<literal> = </literal><replaceable
105
>TIME</replaceable></option></term>
108
This option is <emphasis>optional</emphasis>.
111
The timeout is how long the server will wait for a
112
successful checker run until a client is considered
113
invalid - that is, ineligible to get the data this server
114
holds. By default Mandos will use 1 hour.
117
The <replaceable>TIME</replaceable> is specified as a
118
space-separated number of values, each of which is a
119
number and a one-character suffix. The suffix must be one
120
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
121
<quote>h</quote>, and <quote>w</quote> for days, seconds,
122
minutes, hours, and weeks, respectively. The values are
123
added together to give the total time value, so all of
124
<quote><literal>330s</literal></quote>,
125
<quote><literal>110s 110s 110s</literal></quote>, and
126
<quote><literal>5m 30s</literal></quote> will give a value
127
of five minutes and thirty seconds.

137
This option is <emphasis>optional</emphasis>.
140
How often to run the checker to confirm that a client is
141
still up. <emphasis>Note:</emphasis> a new checker will
142
not be started if an old one is still running. The server
143
will wait for a checker to complete until the above
144
<quote><varname>timeout</varname></quote> occurs, at which
145
time the client will be marked invalid, and any running
146
checker killed. The default interval is 5 minutes.

The format of <replaceable>TIME</replaceable> is the same

This option is <emphasis>optional</emphasis>.
123
How long to wait for external approval before resorting to

use the <option>approved_by_default</option> value. The
125
default is <quote>PT0S</quote>, i.e. not to wait.

Whether to approve a client by default after
161
the <option>approval_delay</option>. The default
162
is <quote>True</quote>.
160
172
This option is <emphasis>optional</emphasis>.
163
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>
175
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>
169
181
<option>-c</option></command></quote>, so
170
182
<varname>PATH</varname> will be searched. The default
171
183
value for the checker command is <quote><literal
172
184
><command>fping</command> <option>-q</option> <option
173
>--</option> %%(host)s</literal></quote>.
185

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

In addition to normal start time expansion, this option
202
<term><option>extended_timeout<literal> = </literal><replaceable
203
>TIME</replaceable></option></term>
206
This option is <emphasis>optional</emphasis>.
209
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.
218
The format of <replaceable>TIME</replaceable> is the same
219
as for <varname>timeout</varname> below.

<term><option>fingerprint<literal> = </literal

226
><replaceable>HEXSTRING</replaceable></option></term>
191
232
This option sets the OpenPGP fingerprint that identifies
192
233
the public key that clients authenticate themselves with
193
through TLS. The string needs to be in hexidecimal form,
234
through TLS. The string needs to be in hexadecimal form,
194
235
but spaces or upper/lower case are not significant.

<option>checker</option> option is modified to a
248
non-standard value without <quote>%%(host)s</quote> in it.

268
not be started if an old one is still running. The server
269
will wait for a checker to complete until the below

342
The timeout is how long the server will wait, after a
343
successful checker run, until a client is disabled and not
344
allowed to get the data this server holds. By default
345
Mandos will use 5 minutes. See also the
346
<option>extended_timeout</option> option.
349
The <replaceable>TIME</replaceable> is specified as an RFC
350
3339 duration; for example

<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
352
one year, two months, three days, four hours, five
