The format starts with a <literal>[<replaceable>section
103
<term><option>timeout<literal> = </literal><replaceable
104

107
This option is <emphasis>optional</emphasis>.
110
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
122
added together to give the total time value, so all of

<quote><literal>330s</literal></quote>,
124
<quote><literal>110s 110s 110s</literal></quote>, and

This option allows you to override the default shell
163

165
the exit code is checked: If the exit code of the command

This option overrides the default shell command that the

server will use to check if the client is still up. Any
172
output of the command will be ignored, only the exit code

client is considered up. The command will be run using

<command>mandos-keygen</command>, when generating output

This option is <emphasis>optional</emphasis>.
204
Extended timeout is an added timeout that is given once
205
after a password has been sent successfully to a client.
206
The timeout is by default longer than the normal timeout,
207
and is used for handling the extra long downtime while a
208
machine is booting up. Time to take into consideration
209
when changing this value is file system checks and quota
210
checks. The default value is 15 minutes.
