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.

302
The timeout is how long the server will wait (for either a
303
successful checker run or a client receiving its secret)
304
until a client is disabled and not allowed to get the data
305
this server holds. By default Mandos will use 1 hour.
308
The <replaceable>TIME</replaceable> is specified as a
309
space-separated number of values, each of which is a
310
number and a one-character suffix. The suffix must be one
311
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
312
<quote>h</quote>, and <quote>w</quote> for days, seconds,
313
minutes, hours, and weeks, respectively. The values are
314
added together to give the total time value, so all of
315
<quote><literal>330s</literal></quote>,
316
<quote><literal>110s 110s 110s</literal></quote>, and
317
<quote><literal>5m 30s</literal></quote> will give a value
318
of five minutes and thirty seconds.
359
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
