The timeout is how long the server will wait for a
112
successful checker run until a client is considered
113
invalid - that is, ineligible to get the data this server
114
holds. By default Mandos will use 1 hour.
117
The <replaceable>TIME</replaceable> is specified as a
118
space-separated number of values, each of which is a
119
number and a one-character suffix. The suffix must be one
120
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
121
<quote>h</quote>, and <quote>w</quote> for days, seconds,
122
minutes, hours, and weeks, respectively. The values are

This option overrides the default shell command that the

This option allows you to override the default shell

<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.

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

successful checker run, until a client is disabled and not
339
allowed to get the data this server holds. By default
340
Mandos will use 5 minutes. See also the

The <replaceable>TIME</replaceable> is specified as an RFC
345
3339 duration; for example

one year, two months, three days, four hours, five
