The file needs to list all clients that should be able to use
88
the service. All clients listed will be regarded as valid, even
89
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

80
clients) will, at startup, override changes done during runtime.

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

<term><literal><varname>timeout</varname></literal></term>

<synopsis><literal>timeout = </literal><replaceable
132
The timeout is how long the server will wait for a
133
successful checker run until a client is considered
134
invalid - that is, ineligible to get the data this server
135
holds. By default Mandos will use 1 hour.
138
The <replaceable>TIME</replaceable> is specified as a
139
space-separated number of values, each of which is a
140
number and a one-character suffix. The suffix must be one
141
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
142
<quote>h</quote>, and <quote>w</quote> for days, seconds,
143
minutes, hours, and weeks, respectively. The values are
144
added together to give the total time value, so all of

146
<quote><literal>110s 110s 110s</literal></quote>, and

This option allows you to override the default shell

command that the server will use to check if the client is
184
still up. Any output of the command will be ignored, only
185
the exit code is checked: If the exit code of the command

This option is <emphasis>optional</emphasis>.
175
This option overrides the default shell command that the

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

<quote><command><filename>/bin/sh</filename>

<command>mandos-keygen</command>, when generating output
187
to be inserted into this file, normally looks for an SSH

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.

The format of <replaceable>TIME</replaceable> is the same
219
as for <varname>timeout</varname> below.

229
This option is <emphasis>required</emphasis>.
209
232
This option sets the OpenPGP fingerprint that identifies
210
233
the public key that clients authenticate themselves with
211
through TLS. The string needs to be in hexidecimal form,
234
through TLS. The string needs to be in hexadecimal form,
212
235
but spaces or upper/lower case are not significant.

non-standard value without <quote>%%(host)s</quote> in it.

Host name for this client. This is not used by the server

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

How often to run the checker to confirm that a client is
267
still up. <emphasis>Note:</emphasis> a new checker will
268
not be started if an old one is still running. The server
269
will wait for a checker to complete until the below
270
<quote><varname>timeout</varname></quote> occurs, at which
271
time the client will be disabled, and any running checker
272
killed. The default interval is 2 minutes.
275
The format of <replaceable>TIME</replaceable> is the same
276
as for <varname>timeout</varname> below.
282
<term><option>secfile<literal> = </literal><replaceable

286
This option is only used if <option>secret</option> is not
287
specified, in which case this option is
288
<emphasis>required</emphasis>.
291
Similar to the <option>secret</option>, except the secret
292
data is in an external file. The contents of the file
293
should <emphasis>not</emphasis> be base64-encoded, but
294
will be sent to clients verbatim.
297
File names of the form <filename>~user/foo/bar</filename>
298
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>
305
<term><option>secret<literal> = </literal><replaceable

309
If this option is not specified, the <option
310
>secfile</option> option is <emphasis>required</emphasis>
224
314
If present, this option must be set to a string of
225
315
base64-encoded binary data. It will be decoded and sent
238
328
lines is that a line beginning with white space adds to
239
329
the value of the previous line, RFC 822-style.
242
If this option is not specified, the <option
243
>secfile</option> option is used instead, but one of them
244
<emphasis>must</emphasis> be present.
250
<term><literal>secfile</literal></term>
252
<synopsis><literal>secfile = </literal><replaceable
253

256
The same as <option>secret</option>, but the secret data
257
is in an external file. The contents of the file should
258
<emphasis>not</emphasis> be base64-encoded, but will be
259
sent to clients verbatim.
262
This option is only used, and <emphasis>must</emphasis> be
263
present, if <option>secret</option> is not specified.
269
<term><literal>host</literal></term>
271
<synopsis><literal>host = </literal><replaceable
272
>STRING</replaceable>
275
Host name for this client. This is not used by the server
276
directly, but can be, and is by default, used by the
277
checker. See the <option>checker</option> option.
335
<term><option>timeout<literal> = </literal><replaceable
336
>TIME</replaceable></option></term>
339
This option is <emphasis>optional</emphasis>.
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
351
<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
352
one year, two months, three days, four hours, five
353
minutes, and six seconds. Some values can be omitted, see
354
RFC 3339 Appendix A for details.
