68
The file needs to list all clients that should be able to use
64
the service. All clients listed will be regarded as valid, even
65
if a client was declared invalid in a previous run of the
69
the service. The settings in this file can be overridden by
70
runtime changes to the server, which it saves across restarts.
71
(See the section called <quote>PERSISTENT STATE</quote> in
72
<citerefentry><refentrytitle>mandos</refentrytitle><manvolnum
73
>8</manvolnum></citerefentry>.) However, any <emphasis
74
>changes</emphasis> to this file (including adding and removing
75
clients) will, at startup, override changes done during runtime.
69
78
The format starts with a <literal>[<replaceable>section
102
<term><option>timeout<literal> = </literal><replaceable
103
>TIME</replaceable></option></term>
106
This option is <emphasis>optional</emphasis>.
109
The timeout is how long the server will wait for a
110
successful checker run until a client is considered
111
invalid - that is, ineligible to get the data this server
112
holds. By default Mandos will use 1 hour.
115
The <replaceable>TIME</replaceable> is specified as a
116
space-separated number of values, each of which is a
117
number and a one-character suffix. The suffix must be one
118
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
119
<quote>h</quote>, and <quote>w</quote> for days, seconds,
120
minutes, hours, and weeks, respectively. The values are
121
added together to give the total time value, so all of
122
<quote><literal>330s</literal></quote>,
123
<quote><literal>110s 110s 110s</literal></quote>, and
124
<quote><literal>5m 30s</literal></quote> will give a value
125
of five minutes and thirty seconds.
131
<term><option>interval<literal> = </literal><replaceable
132
>TIME</replaceable></option></term>
135
This option is <emphasis>optional</emphasis>.
138
How often to run the checker to confirm that a client is
139
still up. <emphasis>Note:</emphasis> a new checker will
140
not be started if an old one is still running. The server
141
will wait for a checker to complete until the above
142
<quote><varname>timeout</varname></quote> occurs, at which
143
time the client will be marked invalid, and any running
144
checker killed. The default interval is 5 minutes.
147
The format of <replaceable>TIME</replaceable> is the same
148
as for <varname>timeout</varname> above.
111
<term><option>approval_delay<literal> = </literal><replaceable
112

115
This option is <emphasis>optional</emphasis>.
118
How long to wait for external approval before resorting to
119
use the <option>approved_by_default</option> value. The
120
default is <quote>0s</quote>, i.e. not to wait.

The format of <replaceable>TIME</replaceable> is the same
124
as for <varname>timeout</varname> below.
130

152
>false</literal> | <literal>off</literal> }</option></term>
155
Whether to approve a client by default after
156
the <option>approval_delay</option>. The default
157
is <quote>True</quote>.
158
167
This option is <emphasis>optional</emphasis>.
161
This option allows you to override the default shell
162
command that the server will use to check if the client is
163
still up. Any output of the command will be ignored, only
164
the exit code is checked: If the exit code of the command
165
is zero, the client is considered up. The command will be
166
run using <quote><command><filename>/bin/sh</filename>
170
This option overrides the default shell command that the
171
server will use to check if the client is still up. Any
172
output of the command will be ignored, only the exit code
173
is checked: If the exit code of the command is zero, the
174
client is considered up. The command will be run using
175
<quote><command><filename>/bin/sh</filename>
167
176
<option>-c</option></command></quote>, so
168
177
<varname>PATH</varname> will be searched. The default
169
178
value for the checker command is <quote><literal
170
179
><command>fping</command> <option>-q</option> <option
171
>--</option> %(host)s</literal></quote>.
180

183
In addition to normal start time expansion, this option
191
<term><option>extended_timeout<literal> = </literal><replaceable
192
>TIME</replaceable></option></term>
195
This option is <emphasis>optional</emphasis>.
198
Extended timeout is an added timeout that is given once
199
after a password has been sent successfully to a client.
200
The timeout is by default longer than the normal timeout,
201
and is used for handling the extra long downtime while a
202
machine is booting up. Time to take into consideration
203
when changing this value is file system checks and quota
204
checks. The default value is 15 minutes.
207
The format of <replaceable>TIME</replaceable> is the same
208

<option>checker</option> option is modified to a
237
non-standard value without <quote>%%(host)s</quote> in it.
240
Host name for this client. This is not used by the server

directly, but can be, and is by default, used by the

checker. See the <option>checker</option> option.

252
This option is <emphasis>optional</emphasis>.
255
How often to run the checker to confirm that a client is
256
still up. <emphasis>Note:</emphasis> a new checker will
257
not be started if an old one is still running. The server
258
will wait for a checker to complete until the below
259
<quote><varname>timeout</varname></quote> occurs, at which
260
time the client will be disabled, and any running checker
261
killed. The default interval is 2 minutes.

specified, in which case this option is
277
<emphasis>required</emphasis>.
280
Similar to the <option>secret</option>, except the secret

should <emphasis>not</emphasis> be base64-encoded, but
240

328
This option is <emphasis>optional</emphasis>.
331
The timeout is how long the server will wait, after a
332
successful checker run, until a client is disabled and not
333
allowed to get the data this server holds. By default
334
Mandos will use 5 minutes. See also the
335
<option>extended_timeout</option> option.
338
The <replaceable>TIME</replaceable> is specified as an RFC
339
3339 duration; for example
340
<quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
341
one year, two months, three days, four hours, five
342
minutes, and six seconds. Some values can be omitted, see
343
RFC 3339 Appendix A for details.
