Unknown options are ignored. The used options are as follows:
124
<term><option>timeout<literal> = </literal><replaceable
125
>TIME</replaceable></option></term>
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
<quote><literal>5m 30s</literal></quote> will give a value
144
of five minutes and thirty seconds.

>TIME</replaceable></option></term>
154
How often to run the checker to confirm that a client is
155
still up. <emphasis>Note:</emphasis> a new checker will
156
not be started if an old one is still running. The server
157
will wait for a checker to complete until the above
158
<quote><varname>timeout</varname></quote> occurs, at which
159
time the client will be marked invalid, and any running
160
checker killed. The default interval is 5 minutes.
163
The format of <replaceable>TIME</replaceable> is the same
164
as for <varname>timeout</varname> above.
105
<term><option>approval_delay<literal> = </literal><replaceable

109
This option is <emphasis>optional</emphasis>.
112
How long to wait for external approval before resorting to
113
use the <option>approved_by_default</option> value. The
114
default is <quote>0s</quote>, i.e. not to wait.

118
as for <varname>timeout</varname> below.

Whether to approve a client by default after
150
the <option>approval_delay</option>. The default

is <quote>True</quote>.

161
This option is <emphasis>optional</emphasis>.
174
164
This option allows you to override the default shell
175
165
command that the server will use to check if the client is
176
166
still up. Any output of the command will be ignored, only
185
<term><option>extended_timeout<literal> = </literal><replaceable
186
>TIME</replaceable></option></term>
189
This option is <emphasis>optional</emphasis>.
192
Extended timeout is an added timeout that is given once
193
after a password has been sent sucessfully to a client.
194
The timeout is by default longer than the normal timeout,
195
and is used for handling the extra long downtime while a
196
machine is booting up. Time to take into consideration
197
when changing this value is file system checks and quota
198
checks. The default value is 15 minutes.
201
The format of <replaceable>TIME</replaceable> is the same
202
as for <varname>timeout</varname> below.

This option is <emphasis>required</emphasis>.
199
215
This option sets the OpenPGP fingerprint that identifies
200
216
the public key that clients authenticate themselves with
201
217
through TLS. The string needs to be in hexidecimal form,
224
<term><option><literal>host = </literal><replaceable

228
This option is <emphasis>optional</emphasis>, but highly
229
<emphasis>recommended</emphasis> unless the
230
<option>checker</option> option is modified to a
231
non-standard value without <quote>%%(host)s</quote> in it.
234
Host name for this client. This is not used by the server
235
directly, but can be, and is by default, used by the
236
checker. See the <option>checker</option> option.
242
<term><option>interval<literal> = </literal><replaceable
243

246
This option is <emphasis>optional</emphasis>.
249
How often to run the checker to confirm that a client is
250
still up. <emphasis>Note:</emphasis> a new checker will
251
not be started if an old one is still running. The server
252
will wait for a checker to complete until the below
253
<quote><varname>timeout</varname></quote> occurs, at which
254
time the client will be disabled, and any running checker
255
killed. The default interval is 2 minutes.
258
The format of <replaceable>TIME</replaceable> is the same
259
as for <varname>timeout</varname> below.
265
<term><option>secfile<literal> = </literal><replaceable
266
>FILENAME</replaceable></option></term>
269
This option is only used if <option>secret</option> is not
270
specified, in which case this option is
271
<emphasis>required</emphasis>.
274
Similar to the <option>secret</option>, except the secret
275
data is in an external file. The contents of the file
276
should <emphasis>not</emphasis> be base64-encoded, but
277
will be sent to clients verbatim.
280
File names of the form <filename>~user/foo/bar</filename>
281
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>

292
If this option is not specified, the <option
293
>secfile</option> option is <emphasis>required</emphasis>
212
297
If present, this option must be set to a string of
213
298
base64-encoded binary data. It will be decoded and sent
214
299
to the client matching the above
226
311
lines is that a line beginning with white space adds to
227
312
the value of the previous line, RFC 822-style.
230
If this option is not specified, the <option
231
>secfile</option> option is used instead, but one of them
232
<emphasis>must</emphasis> be present.
238
<term><option>secfile<literal> = </literal><replaceable
239
>FILENAME</replaceable></option></term>
242
Similar to the <option>secret</option>, except the secret

data is in an external file. The contents of the file
244
should <emphasis>not</emphasis> be base64-encoded, but
245
will be sent to clients verbatim.
248
This option is only used, and <emphasis>must</emphasis> be
249
present, if <option>secret</option> is not specified.
255
<term><option><literal>host = </literal><replaceable
256
>STRING</replaceable></option></term>
259
Host name for this client. This is not used by the server
260
directly, but can be, and is by default, used by the
261
checker. See the <option>checker</option> option.
318
<term><option>timeout<literal> = </literal><replaceable
319
>TIME</replaceable></option></term>
322
This option is <emphasis>optional</emphasis>.
325
The timeout is how long the server will wait, after a
326
successful checker run, until a client is disabled and not
327
allowed to get the data this server holds. By default
328
Mandos will use 5 minutes. See also the
329
<option>extended_timeout</option> option.
332
The <replaceable>TIME</replaceable> is specified as a
333
space-separated number of values, each of which is a
334
number and a one-character suffix. The suffix must be one
335
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
336
<quote>h</quote>, and <quote>w</quote> for days, seconds,
337
minutes, hours, and weeks, respectively. The values are
338
added together to give the total time value, so all of
339
<quote><literal>330s</literal></quote>,
340
<quote><literal>110s 110s 110s</literal></quote>, and
341

342
of five minutes and thirty seconds.
