The file needs to list all clients that should be able to use
66
the service. All clients listed will be regarded as valid, even
67
if a client was declared invalid in a previous run of the
73
the service. The settings in this file can be overridden by
74
runtime changes to the server, which it saves across restarts.

(See the section called <quote>PERSISTENT STATE</quote> in
76
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
77

78

79
clients) will, at startup, override changes done during runtime.

The format starts with a <literal>[<replaceable>section
104
<term><option>timeout<literal> = </literal><replaceable
105
>TIME</replaceable></option></term>
108
This option is <emphasis>optional</emphasis>.
111
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
123
added together to give the total time value, so all of
124
<quote><literal>330s</literal></quote>,
125
<quote><literal>110s 110s 110s</literal></quote>, and
126
<quote><literal>5m 30s</literal></quote> will give a value
127
of five minutes and thirty seconds.

137
This option is <emphasis>optional</emphasis>.
140
How often to run the checker to confirm that a client is
141
still up. <emphasis>Note:</emphasis> a new checker will
142
not be started if an old one is still running. The server
143
will wait for a checker to complete until the above
144
<quote><varname>timeout</varname></quote> occurs, at which
145
time the client will be marked invalid, and any running
146
checker killed. The default interval is 5 minutes.

This option is <emphasis>optional</emphasis>.

How long to wait for external approval before resorting to

124
default is <quote>PT0S</quote>, i.e. not to wait.

Whether to approve a client by default after
160
the <option>approval_delay</option>. The default
161
is <quote>True</quote>.
160
171
This option is <emphasis>optional</emphasis>.
163
This option allows you to override the default shell
164
command that the server will use to check if the client is
165
still up. Any output of the command will be ignored, only
166
the exit code is checked: If the exit code of the command
167
is zero, the client is considered up. The command will be
168
run using <quote><command><filename>/bin/sh</filename>
174
This option overrides the default shell command that the
175
server will use to check if the client is still up. Any
176
output of the command will be ignored, only the exit code
177
is checked: If the exit code of the command is zero, the
178
client is considered up. The command will be run using
179
<quote><command><filename>/bin/sh</filename>
169
180
<option>-c</option></command></quote>, so
170
181
<varname>PATH</varname> will be searched. The default
171
182
value for the checker command is <quote><literal
172
183
><command>fping</command> <option>-q</option> <option
173

184

185
<command>mandos-keygen</command>, when generating output
186
to be inserted into this file, normally looks for an SSH
187
server on the Mandos client, and, if it find one, outputs
188
a <option>checker</option> option to check for the
189
client’s key fingerprint – this is more secure against

In addition to normal start time expansion, this option
201
<term><option>extended_timeout<literal> = </literal><replaceable

205
This option is <emphasis>optional</emphasis>.
208
Extended timeout is an added timeout that is given once
209
after a password has been sent successfully to a client.
210
The timeout is by default longer than the normal timeout,
211
and is used for handling the extra long downtime while a
212
machine is booting up. Time to take into consideration
213
when changing this value is file system checks and quota
214
checks. The default value is 15 minutes.

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

Mandos will use 5 minutes. See also the

The <replaceable>TIME</replaceable> is specified as an RFC
349
3339 duration; for example

351
one year, two months, three days, four hours, five
