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
138
added together to give the total time value, so all of

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

158

159

176
This option allows you to override the default shell
165
177
command that the server will use to check if the client is
166
still up. Any output of the command will be ignored, only
167
the exit code is checked: If the exit code of the command
168
is zero, the client is considered up. The command will be
169
run using <quote><command><filename>/bin/sh</filename>
170
<option>-c</option></command></quote>, so
171
<varname>PATH</varname> will be searched. The default
172
value for the checker command is <quote><literal

179
the exit code is checked. The command will be run using
180
<quote><command><filename>/bin/sh</filename>

182
command is <quote><literal><command>fping</command>

In addition to normal start time expansion, this option
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 successfully 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.

253
<quote><varname>timeout</varname></quote> occurs, at which

<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.

File names of the form <filename>~user/foo/bar</filename>

<term><literal>secret</literal></term>
212
<synopsis><literal>secret = </literal><replaceable
213
>BASE64_ENCODED_DATA</replaceable>
297
216
If present, this option must be set to a string of
298
217
base64-encoded binary data. It will be decoded and sent
299
218
to the client matching the above
300
219
<option>fingerprint</option>. This should, of course, be
301
220
OpenPGP encrypted data, decryptable only by the client.
302
The program <citerefentry><refentrytitle><command
303
>mandos-keygen</command></refentrytitle><manvolnum
304
>8</manvolnum></citerefentry> can, using its
305
<option>--password</option> option, be used to generate
309
Note: this value of this option will probably be very
310
long. A useful feature to avoid having unreadably-long
311
lines is that a line beginning with white space adds to
312
the value of the previous line, RFC 822-style.
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
<quote><literal>5m 30s</literal></quote> will give a value
342
of five minutes and thirty seconds.
221
<!-- The program <citerefentry><refentrytitle><command -->
222
<!-- >mandos-keygen</command></refentrytitle><manvolnum -->
223
<!-- >8</manvolnum></citerefentry> can be used to generate it, -->
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.
