<title>DESCRIPTION</title>
60
The file &CONFPATH; is a configuration file for <citerefentry
61
><refentrytitle>mandos</refentrytitle>
62
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
63
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 format starts with a <literal>[<replaceable>section
70
header</replaceable>]</literal> which is either
71
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
72
name</replaceable>]</literal>. The <replaceable>client
73
name</replaceable> can be anything, and is not tied to a host
74
name. Following the section header is any number of
75
<quote><varname><replaceable>option</replaceable
76
></varname>=<replaceable>value</replaceable></quote> entries,
77
with continuations in the style of RFC 822. <quote><varname
78
><replaceable>option</replaceable></varname>: <replaceable
79
>value</replaceable></quote> is also accepted. Note that
80
leading whitespace is removed from values. Values can contain
81
format strings which refer to other values in the same section,
82
or values in the <quote>DEFAULT</quote> section (see <xref
83
linkend="expansion"/>). Lines beginning with <quote>#</quote>
84
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>
92
<emphasis>Note:</emphasis> all option values are subject to
93
start time expansion, see <xref linkend="expansion"/>.
96
Unknown options are ignored. The used options are as follows:
94
<refsect1 id="default">
95
<title>DEFAULT</title>
97
The paramters for <literal>[DEFAULT]</literal> are:
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.
154
<term><option>checker<literal> = </literal><replaceable
155
>COMMAND</replaceable></option></term>
158
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>
161
127
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>
167
<option>-c</option></command></quote>, so
168
<varname>PATH</varname> will be searched. The default
169
value for the checker command is <quote><literal
170
><command>fping</command> <option>-q</option> <option
171
>--</option> %(host)s</literal></quote>.
174
In addition to normal start time expansion, this option
175
will also be subject to runtime expansion; see <xref
176
linkend="expansion"/>.
182
<term><option>fingerprint<literal> = </literal
183
><replaceable>HEXSTRING</replaceable></option></term>
186
This option is <emphasis>required</emphasis>.
189
This option sets the OpenPGP fingerprint that identifies
190
the public key that clients authenticate themselves with
191
through TLS. The string needs to be in hexidecimal form,
192
but spaces or upper/lower case are not significant.
198
<term><option>secret<literal> = </literal><replaceable
199
>BASE64_ENCODED_DATA</replaceable></option></term>
202
If this option is not specified, the <option
203
>secfile</option> option is <emphasis>required</emphasis>
207
If present, this option must be set to a string of
208
base64-encoded binary data. It will be decoded and sent
209
to the client matching the above
210
<option>fingerprint</option>. This should, of course, be
211
OpenPGP encrypted data, decryptable only by the client.
212
The program <citerefentry><refentrytitle><command
213
>mandos-keygen</command></refentrytitle><manvolnum
214
>8</manvolnum></citerefentry> can, using its
215
<option>--password</option> option, be used to generate
219
Note: this value of this option will probably be very
220
long. A useful feature to avoid having unreadably-long
221
lines is that a line beginning with white space adds to
222
the value of the previous line, RFC 822-style.
228
<term><option>secfile<literal> = </literal><replaceable
229
>FILENAME</replaceable></option></term>
232
This option is only used if <option>secret</option> is not
233
specified, in which case this option is
234
<emphasis>required</emphasis>.
237
Similar to the <option>secret</option>, except the secret
238
data is in an external file. The contents of the file
239
should <emphasis>not</emphasis> be base64-encoded, but
240
will be sent to clients verbatim.
246
<term><option><literal>host = </literal><replaceable
247
>STRING</replaceable></option></term>
250
This option is <emphasis>optional</emphasis>, but highly
251
<emphasis>recommended</emphasis> unless the
252
<option>checker</option> option is modified to a
253
non-standard value without <quote>%(host)s</quote> in it.
256
Host name for this client. This is not used by the server
257
directly, but can be, and is by default, used by the
258
checker. See the <option>checker</option> option.

Any string in an option value of the form

attributes that are useful so they may be preserved to any new

Note that this means that, in order to include an actual
308
percent character (<quote>%</quote>) in a
309
<varname>checker</varname> option, <emphasis>four</emphasis>
310
percent characters in a row (<quote>%%%%</quote>) must be
311
entered. Also, a bad format here will lead to an immediate
312
but <emphasis>silent</emphasis> run-time fatal exit; debug

mode is needed to expose an error of this kind.
