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

the service. All clients listed will be regarded as valid, even

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.

174
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>
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>
169
183
<option>-c</option></command></quote>, so
170
184
<varname>PATH</varname> will be searched. The default
171
185
value for the checker command is <quote><literal

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
192
client’s SSH key fingerprint – this is more secure against

204
<term><option>extended_timeout<literal> = </literal><replaceable

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.

This option is <emphasis>required</emphasis>.
191
This option sets the OpenPGP fingerprint that identifies
192
the public key that clients authenticate themselves with
193
through TLS. The string needs to be in hexidecimal form,
194
but spaces or upper/lower case are not significant.
231
This option is <emphasis>required</emphasis> if the
232
<option>key_id</option> is not set, and
233
<emphasis>optional</emphasis> otherwise.
236
This option sets the OpenPGP fingerprint that (before
237
GnuTLS 3.6.0) identified the public key that clients
238
authenticate themselves with through TLS. The string
239
needs to be in hexadecimal form, but spaces or upper/lower

This option is <emphasis>optional</emphasis>.
290
How often to run the checker to confirm that a client is
291
still up. <emphasis>Note:</emphasis> a new checker will
292
not be started if an old one is still running. The server
293
will wait for a checker to complete until the below
294
<quote><varname>timeout</varname></quote> occurs, at which
295
time the client will be disabled, and any running checker
296
killed. The default interval is 2 minutes.

If present, this option must be set to a string of
210
339
base64-encoded binary data. It will be decoded and sent
211
to the client matching the above

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

successful checker run, until a client is disabled and not
368
allowed to get the data this server holds. By default
369
Mandos will use 5 minutes. See also the

The <replaceable>TIME</replaceable> is specified as an RFC

376
one year, two months, three days, four hours, five
