The file needs to list all clients that should be able to use
65
the service. All clients listed will be regarded as valid, even
66
if a client was declared invalid in a previous run of the

the service. The settings in this file can be overridden by
77
runtime changes to the server, which it saves across restarts.

(See the section called <quote>PERSISTENT STATE</quote> in

82
clients) will, at startup, override changes done during runtime.

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 a
111
successful checker run until a client is considered
112
invalid - that is, ineligible to get the data this server
113
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
123
<quote><literal>330s</literal></quote>,
124
<quote><literal>110s 110s 110s</literal></quote>, and
125

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

run using <quote><command><filename>/bin/sh</filename>
177
This option overrides the default shell command that the
178
server will use to check if the client is still up. Any
179
output of the command will be ignored, only the exit code
180
is checked: If the exit code of the command is zero, the
181
client is considered up. The command will be run using
182
<quote><command><filename>/bin/sh</filename>
168
183
<option>-c</option></command></quote>, so
169
184
<varname>PATH</varname> will be searched. The default

188
<command>mandos-keygen</command>, when generating output
189
to be inserted into this file, normally looks for an SSH
190
server on the Mandos client, and, if it finds one, outputs
191
a <option>checker</option> option to check for the

208
This option is <emphasis>optional</emphasis>.
211
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
215
machine is booting up. Time to take into consideration
216
when changing this value is file system checks and quota
217
checks. The default value is 15 minutes.
