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
75
the service. The settings in this file can be overridden by
76
runtime changes to the server, which it saves across restarts.

(See the section called <quote>PERSISTENT STATE</quote> in
78
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
79
>8</manvolnum></citerefentry>.) However, any <emphasis
80
>changes</emphasis> to this file (including adding and removing
81
clients) will, at startup, override changes done during runtime.

84
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.

<term><option>interval<literal> = </literal><replaceable
134
>TIME</replaceable></option></term>
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.

The format of <replaceable>TIME</replaceable> is the same

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

How long to wait for external approval before resorting to

use the <option>approved_by_default</option> value. The
126
default is <quote>PT0S</quote>, i.e. not to wait.

Whether to approve a client by default after
162
the <option>approval_delay</option>. The default
163
is <quote>True</quote>.
160
173
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>
176
This option overrides the default shell command that the
177
server will use to check if the client is still up. Any
178
output of the command will be ignored, only the exit code
179
is checked: If the exit code of the command is zero, the
180
client is considered up. The command will be run using
181
<quote><command><filename>/bin/sh</filename>
169
182
<option>-c</option></command></quote>, so
170
183
<varname>PATH</varname> will be searched. The default
171
184
value for the checker command is <quote><literal
172
185
><command>fping</command> <option>-q</option> <option
173
>--</option> %%(host)s</literal></quote>.
186

187
<command>mandos-keygen</command>, when generating output
188
to be inserted into this file, normally looks for an SSH
189
server on the Mandos client, and, if it find one, outputs
190
a <option>checker</option> option to check for the
191
client’s key fingerprint – this is more secure against

In addition to normal start time expansion, this option
203
<term><option>extended_timeout<literal> = </literal><replaceable
204
>TIME</replaceable></option></term>
207
This option is <emphasis>optional</emphasis>.
210
Extended timeout is an added timeout that is given once
211
after a password has been sent successfully to a client.
212
The timeout is by default longer than the normal timeout,
213
and is used for handling the extra long downtime while a
214
machine is booting up. Time to take into consideration
215
when changing this value is file system checks and quota
216
checks. The default value is 15 minutes.
219
The format of <replaceable>TIME</replaceable> is the same
220
as for <varname>timeout</varname> below.

<term><option>fingerprint<literal> = </literal

227
><replaceable>HEXSTRING</replaceable></option></term>
191
233
This option sets the OpenPGP fingerprint that identifies
192
234
the public key that clients authenticate themselves with
193
through TLS. The string needs to be in hexidecimal form,
235
through TLS. The string needs to be in hexadecimal form,
194
236
but spaces or upper/lower case are not significant.

249
non-standard value without <quote>%%(host)s</quote> in it.

not be started if an old one is still running. The server
270

343
The timeout is how long the server will wait, after a
344
successful checker run, until a client is disabled and not
345
allowed to get the data this server holds. By default
346
Mandos will use 5 minutes. See also the
347
<option>extended_timeout</option> option.
350
The <replaceable>TIME</replaceable> is specified as an RFC
351
3339 duration; for example

<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
353
one year, two months, three days, four hours, five
