The file needs to list all clients that should be able to use
75
the service. The settings in this file can be overridden by
76
runtime changes to the server, which it saves across restarts.

(See the section called <quote>PERSISTENT STATE</quote> in

This option is <emphasis>optional</emphasis>.

How long to wait for external approval before resorting to

106
This option is <emphasis>optional</emphasis>.
109
The timeout is how long the server will wait for a
110
successful checker run until a client is considered
111
invalid - that is, ineligible to get the data this server
112
holds. By default Mandos will use 1 hour.
115
The <replaceable>TIME</replaceable> is specified as a
116
space-separated number of values, each of which is a
117
number and a one-character suffix. The suffix must be one
118
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
119
<quote>h</quote>, and <quote>w</quote> for days, seconds,
120
minutes, hours, and weeks, respectively. The values are
121
added together to give the total time value, so all of
122
<quote><literal>330s</literal></quote>,
123
<quote><literal>110s 110s 110s</literal></quote>, and
124
<quote><literal>5m 30s</literal></quote> will give a value
125
of five minutes and thirty seconds.

This option is <emphasis>optional</emphasis>.
138
How often to run the checker to confirm that a client is
139
still up. <emphasis>Note:</emphasis> a new checker will
140
not be started if an old one is still running. The server
141
will wait for a checker to complete until the above
142
<quote><varname>timeout</varname></quote> occurs, at which
143
time the client will be marked invalid, and any running
144
checker killed. The default interval is 5 minutes.

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

as for <varname>timeout</varname> above.

173
158
This option is <emphasis>optional</emphasis>.
176
This option overrides the default shell command that the
177
server will use to check if the client is still up. Any
178
output of the command will be ignored, only the exit code
179
is checked: If the exit code of the command is zero, the
180
client is considered up. The command will be run using
181
<quote><command><filename>/bin/sh</filename>
161
This option allows you to override the default shell
162
command that the server will use to check if the client is
163
still up. Any output of the command will be ignored, only
164
the exit code is checked: If the exit code of the command
165
is zero, the client is considered up. The command will be
166
run using <quote><command><filename>/bin/sh</filename>
182
167
<option>-c</option></command></quote>, so
183
168
<varname>PATH</varname> will be searched. The default
184
169
value for the checker command is <quote><literal
185
170
><command>fping</command> <option>-q</option> <option
186
>--</option> %%(host)s</literal></quote>. Note that
187
<command>mandos-keygen</command>, when generating output
188
to be inserted into this file, normally looks for an SSH
189
server on the Mandos client, and, if it find one, outputs
190
a <option>checker</option> option to check for the
191
client’s key fingerprint – this is more secure against
171
>--</option> %(host)s</literal></quote>.
195
174
In addition to normal start time expansion, this option
203
<term><option>extended_timeout<literal> = </literal><replaceable
204
>TIME</replaceable></option></term>
207
This option is <emphasis>optional</emphasis>.
210
Extended timeout is an added timeout that is given once
211
after a password has been sent successfully to a client.
212
The timeout is by default longer than the normal timeout,
213
and is used for handling the extra long downtime while a
214
machine is booting up. Time to take into consideration
215
when changing this value is file system checks and quota
216
checks. The default value is 15 minutes.
219
The format of <replaceable>TIME</replaceable> is the same
220
as for <varname>timeout</varname> below.

This option sets the OpenPGP fingerprint that identifies
234
190
the public key that clients authenticate themselves with
235
through TLS. The string needs to be in hexadecimal form,
236
but spaces or upper/lower case are not significant.

<option>checker</option> option is modified to a
265
non-standard value without <quote>%%(host)s</quote> in it.
268
Host name for this client. This is not used by the server
269
directly, but can be, and is by default, used by the

checker. See the <option>checker</option> option.

This option is <emphasis>optional</emphasis>.
283
How often to run the checker to confirm that a client is
284
still up. <emphasis>Note:</emphasis> a new checker will
285
not be started if an old one is still running. The server
286
will wait for a checker to complete until the below
287
<quote><varname>timeout</varname></quote> occurs, at which
288
time the client will be disabled, and any running checker
289
killed. The default interval is 2 minutes.

This option is only used if <option>secret</option> is not
304
specified, in which case this option is
305
<emphasis>required</emphasis>.
308
Similar to the <option>secret</option>, except the secret
309
data is in an external file. The contents of the file
310
should <emphasis>not</emphasis> be base64-encoded, but
311
will be sent to clients verbatim.

File names of the form <filename>~user/foo/bar</filename>
315
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>

192
but spaces or upper/lower case are not significant.
331
207
If present, this option must be set to a string of
332
208
base64-encoded binary data. It will be decoded and sent
333
to the client matching the above <option>key_id</option>
334
or <option>fingerprint</option>. This should, of course,
335
be OpenPGP encrypted data, decryptable only by the client.

The timeout is how long the server will wait, after a
360
successful checker run, until a client is disabled and not
361
allowed to get the data this server holds. By default
362
Mandos will use 5 minutes. See also the
363
<option>extended_timeout</option> option.
366
The <replaceable>TIME</replaceable> is specified as an RFC
367
3339 duration; for example
368
<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
369
one year, two months, three days, four hours, five
370
minutes, and six seconds. Some values can be omitted, see
371
RFC 3339 Appendix A for details.

specified, in which case this option is
