The file needs to list all clients that should be able to use

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
125

killed. The default interval is 5 minutes.

This option overrides the default shell command that the
174
server will use to check if the client is still up. Any
175
output of the command will be ignored, only the exit code
176

162
This option allows you to override the default shell
163
command that the server will use to check if the client is
164
still up. Any output of the command will be ignored, only
165
the exit code is checked: If the exit code of the command
166
is zero, the client is considered up. The command will be
167
run using <quote><command><filename>/bin/sh</filename>
179
168
<option>-c</option></command></quote>, so
180
169
<varname>PATH</varname> will be searched. The default

170
value for the checker command is <quote><literal
182
171
><command>fping</command> <option>-q</option> <option

184
<command>mandos-keygen</command>, when generating output
185
to be inserted into this file, normally looks for an SSH
186
server on the Mandos client, and, if it find one, outputs
187
a <option>checker</option> option to check for the
188
client’s key fingerprint – this is more secure against

<term><option>extended_timeout<literal> = </literal><replaceable

204
This option is <emphasis>optional</emphasis>.
207
Extended timeout is an added timeout that is given once
208
after a password has been sent successfully to a client.
209
The timeout is by default longer than the normal timeout,
210
and is used for handling the extra long downtime while a
211
machine is booting up. Time to take into consideration
212
when changing this value is file system checks and quota
213
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
342
allowed to get the data this server holds. By default
343
Mandos will use 5 minutes. See also the

347
The <replaceable>TIME</replaceable> is specified as an RFC
348
3339 duration; for example

<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
350
one year, two months, three days, four hours, five
