This option overrides the default shell command that the
171
server will use to check if the client is still up. Any
172
output of the command will be ignored, only the exit code

126
The timeout is how long the server will wait for a
127
successful checker run until a client is considered
128
invalid - that is, ineligible to get the data this server
129
holds. By default Mandos will use 1 hour.
132
The <replaceable>TIME</replaceable> is specified as a
133
space-separated number of values, each of which is a
134
number and a one-character suffix. The suffix must be one
135
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
136
<quote>h</quote>, and <quote>w</quote> for days, seconds,
137
minutes, hours, and weeks, respectively. The values are

This option allows you to override the default shell
177
command that the server will use to check if the client is
178
still up. The output of the command will be ignored, only
179
the exit code is checked. The command will be run using
175
180
<quote><command><filename>/bin/sh</filename>
176
<option>-c</option></command></quote>, so
177
<varname>PATH</varname> will be searched. The default

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.

<emphasis>required</emphasis>.
280
Similar to the <option>secret</option>, except the secret
281
data is in an external file. The contents of the file
282
should <emphasis>not</emphasis> be base64-encoded, but
283
will be sent to clients verbatim.

212
<synopsis><literal>secret = </literal><replaceable

>BASE64_ENCODED_DATA</replaceable>
303
216
If present, this option must be set to a string of
304
217
base64-encoded binary data. It will be decoded and sent
305
218
to the client matching the above
306
219
<option>fingerprint</option>. This should, of course, be
307
220
OpenPGP encrypted data, decryptable only by the client.
308
The program <citerefentry><refentrytitle><command
309
>mandos-keygen</command></refentrytitle><manvolnum
310
>8</manvolnum></citerefentry> can, using its
311
<option>--password</option> option, be used to generate
315
Note: this value of this option will probably be very
316
long. A useful feature to avoid having unreadably-long
317
lines is that a line beginning with white space adds to
318
the value of the previous line, RFC 822-style.
324
<term><option>timeout<literal> = </literal><replaceable
325
>TIME</replaceable></option></term>
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
344
added together to give the total time value, so all of
345
<quote><literal>330s</literal></quote>,
346
<quote><literal>110s 110s 110s</literal></quote>, and
347
<quote><literal>5m 30s</literal></quote> will give a value
348
of five minutes and thirty seconds.

<term><option>enabled<literal> = </literal>{ <literal

357
>no</literal> | <literal>false</literal> | <literal
358

361
Whether this client should be enabled by default. The
362
default is <quote>true</quote>.

227
Note: this value of this option will probably run over
228
many lines, and will then have to use the fact that a line
229
beginning with white space adds to the value of the
230
previous line, RFC 822-style.
