<title>DESCRIPTION</title>
62
The file &CONFPATH; is a configuration file for <citerefentry
63
><refentrytitle>mandos</refentrytitle>
64
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
65
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
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

<title>OPTIONS</title>

<emphasis>Note:</emphasis> all option values are subject to
95
start time expansion, see <xref linkend="expansion"/>.
98
Unknown options are ignored. The used options are as follows:
94
<refsect1 id="default">
95
<title>DEFAULTS</title>
97
The paramters for <literal>[DEFAULT]</literal> are:
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.
133
<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.
149
The format of <replaceable>TIME</replaceable> is the same
150
as for <varname>timeout</varname> above.
156
<term><option>checker<literal> = </literal><replaceable
157
>COMMAND</replaceable></option></term>
160
This option is <emphasis>optional</emphasis>.
103
<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.
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>
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
168
run using <quote><command><filename>/bin/sh</filename>
169
<option>-c</option></command></quote>, so
170
<varname>PATH</varname> will be searched. The default
171
value for the checker command is <quote><literal
172
><command>fping</command> <option>-q</option> <option
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
178
linkend="expansion"/>.
184
<term><option>fingerprint<literal> = </literal
185
><replaceable>HEXSTRING</replaceable></option></term>
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>secret<literal> = </literal><replaceable
201
>BASE64_ENCODED_DATA</replaceable></option></term>
204
If this option is not specified, the <option
205
>secfile</option> option is <emphasis>required</emphasis>
209
If present, this option must be set to a string of
210
base64-encoded binary data. It will be decoded and sent
211
to the client matching the above
212
<option>fingerprint</option>. This should, of course, be
213
OpenPGP encrypted data, decryptable only by the client.
214
The program <citerefentry><refentrytitle><command
215
>mandos-keygen</command></refentrytitle><manvolnum
216
>8</manvolnum></citerefentry> can, using its
217
<option>--password</option> option, be used to generate
221
Note: this value of this option will probably be very
222
long. A useful feature to avoid having unreadably-long
223
lines is that a line beginning with white space adds to
224
the value of the previous line, RFC 822-style.
230
<term><option>secfile<literal> = </literal><replaceable
231
>FILENAME</replaceable></option></term>
234
This option is only used if <option>secret</option> is not
235
specified, in which case this option is
236
<emphasis>required</emphasis>.
239
Similar to the <option>secret</option>, except the secret
240
data is in an external file. The contents of the file
241
should <emphasis>not</emphasis> be base64-encoded, but
242
will be sent to clients verbatim.
245
File names of the form <filename>~user/foo/bar</filename>
246
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>
253
<term><option><literal>host = </literal><replaceable
254
>STRING</replaceable></option></term>
257
This option is <emphasis>optional</emphasis>, but highly
258
<emphasis>recommended</emphasis> unless the
259
<option>checker</option> option is modified to a
260
non-standard value without <quote>%(host)s</quote> in it.
263
Host name for this client. This is not used by the server
264
directly, but can be, and is by default, used by the
265
checker. See the <option>checker</option> option.
