The file &CONFPATH; is a configuration file for <citerefentry
85
><refentrytitle>mandos</refentrytitle>
86
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
87
The file needs to list all clients that should be able to use
88
the service. All clients listed will be regarded as valid, even
89
if a client was declared invalid in a previous run of the
93
The format starts with a <literal>[<replaceable>section
94
header</replaceable>]</literal> which is either
95
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
96
name</replaceable>]</literal>. The <replaceable>client
97
name</replaceable> can be anything, and is not tied to a host
98
name. Following the section header is any number of
99
<quote><varname><replaceable>option</replaceable
100
></varname>=<replaceable>value</replaceable></quote> entries,
101
with continuations in the style of RFC 822. <quote><varname
102
><replaceable>option</replaceable></varname>: <replaceable
103
>value</replaceable></quote> is also accepted. Note that
104
leading whitespace is removed from values. Values can contain
105
format strings which refer to other values in the same section,
106
or values in the <quote>DEFAULT</quote> section (see <xref

108
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

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

The paramters for <literal>[DEFAULT]</literal> are:
126
<term><literal><varname>timeout</varname></literal></term>
128
<synopsis><literal>timeout = </literal><replaceable
132
The timeout is how long the server will wait for a
133
successful checker run until a client is considered
134
invalid - that is, ineligible to get the data this server
135
holds. By default Mandos will use 1 hour.
138
The <replaceable>TIME</replaceable> is specified as a
139
space-separated number of values, each of which is a
140
number and a one-character suffix. The suffix must be one
141
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
142
<quote>h</quote>, and <quote>w</quote> for days, seconds,
143
minutes, hours, and weeks, respectively. The values are
144
added together to give the total time value, so all of
145
<quote><literal>330s</literal></quote>,
146
<quote><literal>110s 110s 110s</literal></quote>, and
147
<quote><literal>5m 30s</literal></quote> will give a value
148
of five minutes and thirty seconds.
154
<term><literal><varname>interval</varname></literal></term>
156
<synopsis><literal>interval = </literal><replaceable
160
How often to run the checker to confirm that a client is
161
still up. <emphasis>Note:</emphasis> a new checker will
162
not be started if an old one is still running. The server
163
will wait for a checker to complete until the above
164
<quote><varname>timeout</varname></quote> occurs, at which
165
time the client will be marked invalid, and any running
166
checker killed. The default interval is 5 minutes.
169
The format of <replaceable>TIME</replaceable> is the same
170
as for <varname>timeout</varname> above.
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.

This option allows you to override the default interval
117
used between checkups for disconnected clients. By default

>COMMAND</replaceable>
182
127
This option allows you to override the default shell
183
command that the server will use to check if the client is
184
still up. Any output of the command will be ignored, only
185
the exit code is checked: If the exit code of the command
186
is zero, the client is considered up. The command will be
187
run using <quote><command><filename>/bin/sh</filename>
188
<option>-c</option></command></quote>, so
189
<varname>PATH</varname> will be searched. The default
190
value for the checker command is <quote><literal
191
><command>fping</command> <option>-q</option> <option
192
>--</option> %(host)s</literal></quote>.

In addition to normal start time expansion, this option
196
will also be subject to runtime expansion; see <xref

<term><literal>fingerprint</literal></term>
205
<synopsis><literal>fingerprint = </literal><replaceable
206
>HEXSTRING</replaceable>
209
This option sets the OpenPGP fingerprint that identifies
210
the public key that clients authenticate themselves with
211
through TLS. The string needs to be in hexidecimal form,
212
but spaces or upper/lower case are not significant.

This option sets the openpgp fingerprint that identifies
150
the public certificate that clients authenticates themself
151

<synopsis><literal>secret = </literal><replaceable

>BASE64_ENCODED_DATA</replaceable>
224
If present, this option must be set to a string of
225
base64-encoded binary data. It will be decoded and sent
226
to the client matching the above
227
<option>fingerprint</option>. This should, of course, be
228
OpenPGP encrypted data, decryptable only by the client.
229
The program <citerefentry><refentrytitle><command
230

232

Note: this value of this option will probably be very
237
long. A useful feature to avoid having unreadably-long
238
lines is that a line beginning with white space adds to
239
the value of the previous line, RFC 822-style.

If this option is not specified, the <option
