<title>DESCRIPTION</title>
63
The file &CONFPATH; is a configuration file for <citerefentry
64
><refentrytitle>mandos</refentrytitle>
65
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
66
The file needs to list all clients that should be able to use
67
the service. All clients listed will be regarded as enabled,
68
even if a client was disabled in a previous run of the server.
71
The format starts with a <literal>[<replaceable>section
72
header</replaceable>]</literal> which is either
73
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
74
name</replaceable>]</literal>. The <replaceable>client
75
name</replaceable> can be anything, and is not tied to a host
76
name. Following the section header is any number of
77
<quote><varname><replaceable>option</replaceable
78
></varname>=<replaceable>value</replaceable></quote> entries,
79
with continuations in the style of RFC 822. <quote><varname
80
><replaceable>option</replaceable></varname>: <replaceable
81
>value</replaceable></quote> is also accepted. Note that
82
leading whitespace is removed from values. Values can contain
83
format strings which refer to other values in the same section,
84
or values in the <quote>DEFAULT</quote> section (see <xref
85
linkend="expansion"/>). Lines beginning with <quote>#</quote>
86
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

<emphasis>Note:</emphasis> all option values are subject to

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

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

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

default is <quote>0s</quote>, i.e. not to wait.

Whether to approve a client by default after

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

<term><literal>timeout</literal></term>
106
This option allows you to override the default timeout
107
that clients will get. By default mandos will use 1hr.

<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>
163
127
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

run using <quote><command><filename>/bin/sh</filename>

<varname>PATH</varname> will be searched. The default

value for the checker command is <quote><literal

173
>--</option> %%(host)s</literal></quote>.
176
In addition to normal start time expansion, this option
177
will also be subject to runtime expansion; see <xref

<term><option>fingerprint<literal> = </literal
185

188
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.
200
<term><option><literal>host = </literal><replaceable
201
>STRING</replaceable></option></term>
204
This option is <emphasis>optional</emphasis>, but highly
205
<emphasis>recommended</emphasis> unless the
206
<option>checker</option> option is modified to a
207
non-standard value without <quote>%%(host)s</quote> in it.
210
Host name for this client. This is not used by the server
211
directly, but can be, and is by default, used by the
212
checker. See the <option>checker</option> option.
218
<term><option>interval<literal> = </literal><replaceable
219
>TIME</replaceable></option></term>
222
This option is <emphasis>optional</emphasis>.
225
How often to run the checker to confirm that a client is
226
still up. <emphasis>Note:</emphasis> a new checker will
227
not be started if an old one is still running. The server
228
will wait for a checker to complete until the below
229
<quote><varname>timeout</varname></quote> occurs, at which
230
time the client will be disabled, and any running checker
231
killed. The default interval is 5 minutes.
234
The format of <replaceable>TIME</replaceable> is the same
235
as for <varname>timeout</varname> below.
241
<term><option>secfile<literal> = </literal><replaceable
242
>FILENAME</replaceable></option></term>
245
This option is only used if <option>secret</option> is not
246
specified, in which case this option is
247
<emphasis>required</emphasis>.
250
Similar to the <option>secret</option>, except the secret
251
data is in an external file. The contents of the file
252
should <emphasis>not</emphasis> be base64-encoded, but
253
will be sent to clients verbatim.
256
File names of the form <filename>~user/foo/bar</filename>
257
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>
264
<term><option>secret<literal> = </literal><replaceable
265
>BASE64_ENCODED_DATA</replaceable></option></term>
268
If this option is not specified, the <option
269
>secfile</option> option is <emphasis>required</emphasis>
273
If present, this option must be set to a string of
274
base64-encoded binary data. It will be decoded and sent
275
to the client matching the above
276
<option>fingerprint</option>. This should, of course, be
277
OpenPGP encrypted data, decryptable only by the client.
278
The program <citerefentry><refentrytitle><command
279
>mandos-keygen</command></refentrytitle><manvolnum
280
>8</manvolnum></citerefentry> can, using its
281
<option>--password</option> option, be used to generate
285
Note: this value of this option will probably be very
286
long. A useful feature to avoid having unreadably-long
287
lines is that a line beginning with white space adds to
288
the value of the previous line, RFC 822-style.
294
<term><option>timeout<literal> = </literal><replaceable
295
>TIME</replaceable></option></term>
298
This option is <emphasis>optional</emphasis>.
301
The timeout is how long the server will wait (for either a
302
successful checker run or a client receiving its secret)
303
until a client is disabled and not allowed to get the data
304
this server holds. By default Mandos will use 1 hour.
307
The <replaceable>TIME</replaceable> is specified as a
308
space-separated number of values, each of which is a
309
number and a one-character suffix. The suffix must be one
310
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
311
<quote>h</quote>, and <quote>w</quote> for days, seconds,
312
minutes, hours, and weeks, respectively. The values are
313
added together to give the total time value, so all of
314
<quote><literal>330s</literal></quote>,
315
<quote><literal>110s 110s 110s</literal></quote>, and
316
<quote><literal>5m 30s</literal></quote> will give a value
317
of five minutes and thirty seconds.

<varname>checker</varname> option, <emphasis>four</emphasis>
369
percent characters in a row (<quote>%%%%</quote>) must be

entered. Also, a bad format here will lead to an immediate
