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

machine is booting up. Time to take into consideration
216
when changing this value is file system checks and quota
217

The timeout is how long the server will wait (for either a

305
this server holds. By default Mandos will use 5 minutes.

The timeout is how long the server will wait, after a

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

312
<quote>h</quote>, and <quote>w</quote> for days, seconds,
313

The <replaceable>TIME</replaceable> is specified as an RFC
