<title>DESCRIPTION</title>
64
The file &CONFPATH; is a configuration file for <citerefentry
65
><refentrytitle>mandos</refentrytitle>
66
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
67
The file needs to list all clients that should be able to use
68
the service. All clients listed will be regarded as enabled,
69
even if a client was disabled in a previous run of the server.
72
The format starts with a <literal>[<replaceable>section
73
header</replaceable>]</literal> which is either
74
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
75
name</replaceable>]</literal>. The <replaceable>client
76
name</replaceable> can be anything, and is not tied to a host
77
name. Following the section header is any number of
78
<quote><varname><replaceable>option</replaceable
79
></varname>=<replaceable>value</replaceable></quote> entries,
80
with continuations in the style of RFC 822. <quote><varname
81
><replaceable>option</replaceable></varname>: <replaceable
82
>value</replaceable></quote> is also accepted. Note that
83
leading whitespace is removed from values. Values can contain
84
format strings which refer to other values in the same section,
85
or values in the <quote>DEFAULT</quote> section (see <xref
86
linkend="expansion"/>). Lines beginning with <quote>#</quote>
87
or <quote>;</quote> are ignored and may be used to provide

The file &CONFPATH; is the configuration file for mandos where
84
each client that will be abel to use the service need to be
85
specified. The configuration file is looked on at the startup of
86
the service, so to reenable timedout clients one need to only
87
restart the server. The format starts with a section under []
88
which is eather <literal>[DEFAULT]</literal> or a client
89
name. Values is set through the use of VAR = VALUE pair. Values

Unknown options are ignored. The used options are as follows:

The paramters for <literal>[DEFAULT]</literal> are:

>TIME</replaceable></option></term>
109
This option is <emphasis>optional</emphasis>.
112
How long to wait for external approval before resorting to

114
default is <quote>0s</quote>, i.e. not to wait.
117
The format of <replaceable>TIME</replaceable> is the same
118
as for <varname>timeout</varname> below.

Whether to approve a client by default after

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

This option allows you to override the default timeout
107
that clients will get. By default mandos will use 1hr.
113
<term><literal>interval</literal></term>
116
This option allows you to override the default interval
117
used between checkups for disconnected clients. By default
124
<term><literal>checker</literal></term>
164
127
This option allows you to override the default shell
165
command that the server will use to check if the client is
166
still up. Any output of the command will be ignored, only
167
the exit code is checked: If the exit code of the command
168
is zero, the client is considered up. The command will be
169
run using <quote><command><filename>/bin/sh</filename>
170
<option>-c</option></command></quote>, so
171
<varname>PATH</varname> will be searched. The default
172
value for the checker command is <quote><literal
173
><command>fping</command> <option>-q</option> <option
174
>--</option> %%(host)s</literal></quote>.
177
In addition to normal start time expansion, this option
178
will also be subject to runtime expansion; see <xref
179
linkend="expansion"/>.
185
<term><option>extended_timeout<literal> = </literal><replaceable
186
>TIME</replaceable></option></term>
189
This option is <emphasis>optional</emphasis>.
192
Extended timeout is an added timeout that is given once
193
after a password has been sent successfully to a client.
194
The timeout is by default longer than the normal timeout,
195
and is used for handling the extra long downtime while a
196
machine is booting up. Time to take into consideration
197
when changing this value is file system checks and quota
198
checks. The default value is 15 minutes.
201
The format of <replaceable>TIME</replaceable> is the same
202
as for <varname>timeout</varname> below.
208
<term><option>fingerprint<literal> = </literal
209
><replaceable>HEXSTRING</replaceable></option></term>
212
This option is <emphasis>required</emphasis>.
215
This option sets the OpenPGP fingerprint that identifies
216
the public key that clients authenticate themselves with
217
through TLS. The string needs to be in hexidecimal form,
218
but spaces or upper/lower case are not significant.
224
<term><option><literal>host = </literal><replaceable
225
>STRING</replaceable></option></term>
228
This option is <emphasis>optional</emphasis>, but highly
229
<emphasis>recommended</emphasis> unless the
230
<option>checker</option> option is modified to a
231
non-standard value without <quote>%%(host)s</quote> in it.
234
Host name for this client. This is not used by the server
235
directly, but can be, and is by default, used by the
236
checker. See the <option>checker</option> option.
242
<term><option>interval<literal> = </literal><replaceable
243
>TIME</replaceable></option></term>
246
This option is <emphasis>optional</emphasis>.
249
How often to run the checker to confirm that a client is
250
still up. <emphasis>Note:</emphasis> a new checker will
251
not be started if an old one is still running. The server
252
will wait for a checker to complete until the below
253
<quote><varname>timeout</varname></quote> occurs, at which
254
time the client will be disabled, and any running checker
255
killed. The default interval is 2 minutes.
258
The format of <replaceable>TIME</replaceable> is the same
259
as for <varname>timeout</varname> below.
265
<term><option>secfile<literal> = </literal><replaceable
266
>FILENAME</replaceable></option></term>
269
This option is only used if <option>secret</option> is not
270
specified, in which case this option is
271
<emphasis>required</emphasis>.
274
Similar to the <option>secret</option>, except the secret
275
data is in an external file. The contents of the file
276
should <emphasis>not</emphasis> be base64-encoded, but
277
will be sent to clients verbatim.
280
File names of the form <filename>~user/foo/bar</filename>
281
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>
288
<term><option>secret<literal> = </literal><replaceable
289
>BASE64_ENCODED_DATA</replaceable></option></term>
292
If this option is not specified, the <option
293
>secfile</option> option is <emphasis>required</emphasis>
297
If present, this option must be set to a string of
298
base64-encoded binary data. It will be decoded and sent
299
to the client matching the above
300
<option>fingerprint</option>. This should, of course, be
301
OpenPGP encrypted data, decryptable only by the client.
302
The program <citerefentry><refentrytitle><command
303
>mandos-keygen</command></refentrytitle><manvolnum
304
>8</manvolnum></citerefentry> can, using its
305
<option>--password</option> option, be used to generate
309
Note: this value of this option will probably be very
310
long. A useful feature to avoid having unreadably-long
311
lines is that a line beginning with white space adds to
312
the value of the previous line, RFC 822-style.
318
<term><option>timeout<literal> = </literal><replaceable
319
>TIME</replaceable></option></term>
322
This option is <emphasis>optional</emphasis>.
325
The timeout is how long the server will wait, after a
326
successful checker run, until a client is disabled and not
327
allowed to get the data this server holds. By default
328
Mandos will use 5 minutes. See also the
329
<option>extended_timeout</option> option.
332
The <replaceable>TIME</replaceable> is specified as a
333
space-separated number of values, each of which is a
334
number and a one-character suffix. The suffix must be one
335
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
336
<quote>h</quote>, and <quote>w</quote> for days, seconds,
337
minutes, hours, and weeks, respectively. The values are
338
added together to give the total time value, so all of
339
<quote><literal>330s</literal></quote>,
340
<quote><literal>110s 110s 110s</literal></quote>, and
341
<quote><literal>5m 30s</literal></quote> will give a value
342
of five minutes and thirty seconds.
