Extended timeout is an added timeout that is given once
212
after a password has been sent successfully to a client.
213
The timeout is by default longer than the normal timeout,
214
and is used for handling the extra long downtime while a
215
machine is booting up. Time to take into consideration
216
when changing this value is file system checks and quota
217
checks. The default value is 15 minutes.

301
The timeout is how long the server will wait (for either a
302
successful checker run or a client receiving its secret)
303
until a client is disabled and not allowed to get the data
304
this server holds. By default Mandos will use 1 hour.
307
The <replaceable>TIME</replaceable> is specified as a
308
space-separated number of values, each of which is a
309
number and a one-character suffix. The suffix must be one
310
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
311
<quote>h</quote>, and <quote>w</quote> for days, seconds,
312
minutes, hours, and weeks, respectively. The values are
313
added together to give the total time value, so all of
314
<quote><literal>330s</literal></quote>,
315
<quote><literal>110s 110s 110s</literal></quote>, and
316
<quote><literal>5m 30s</literal></quote> will give a value
317
of five minutes and thirty seconds.
366
The timeout is how long the server will wait, after a
367
successful checker run, until a client is disabled and not
368
allowed to get the data this server holds. By default
369
Mandos will use 5 minutes. See also the
370
<option>extended_timeout</option> option.
373
The <replaceable>TIME</replaceable> is specified as an RFC
374
3339 duration; for example
375
<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
376
one year, two months, three days, four hours, five
377
minutes, and six seconds. Some values can be omitted, see
