The timeout is how long the server will wait (for either a
111
successful checker run or a client receiving its secret)
112
until a client is disabled and not allowed to get the data
113
this server holds. By default Mandos will use 1 hour.
116
The <replaceable>TIME</replaceable> is specified as a
117
space-separated number of values, each of which is a
118
number and a one-character suffix. The suffix must be one
119
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
120
<quote>h</quote>, and <quote>w</quote> for days, seconds,
121
minutes, hours, and weeks, respectively. The values are

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

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
