83
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

The file &CONFPATH; is a configuration file for <citerefentry
83
><refentrytitle>mandos</refentrytitle>
84
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
85
The file needs to list all clients that should be able to use
86
the service. All clients listed will be regarded as valid, even
87
if a client was declared invalid in a previous run of the
91
The format starts with a <literal>[<replaceable>section
92
header</replaceable>]</literal> which is either
93
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
94
name</replaceable>]</literal>. The <replaceable>client
95
name</replaceable> can be anything, and is not tied to a host
96
name. Following the section header is any number of
97
<quote><varname><replaceable>option</replaceable
98
></varname>=<replaceable>value</replaceable></quote> entries,
99
with continuations in the style of RFC 822. <quote><varname
100
><replaceable>option</replaceable></varname>: <replaceable
101
>value</replaceable></quote> is also accepted. Note that
102
leading whitespace is removed from values. Values can contain
103
format strings which refer to other values in the same section,
104
or values in the <quote>DEFAULT</quote> section (see <xref
105
linkend="expansion"/>). Lines beginning with <quote>#</quote>
106
or <quote>;</quote> are ignored and may be used to provide
94
<refsect1 id="default">
95
<title>DEFAULT</title>
97
The paramters for <literal>[DEFAULT]</literal> are:
111
<refsect1 id="options">
112
<title>OPTIONS</title>
114
<emphasis>Note:</emphasis> all option values are subject to
115
start time expansion, see <xref linkend="expansion"/>.
118
Uknown options are ignored. The used options are as follows:
103
<term><literal>timeout</literal></term>
124
<term><literal><varname>timeout</varname></literal></term>
106
This option allows you to override the default timeout
107
that clients will get. By default mandos will use 1hr.
126
<synopsis><literal>timeout = </literal><replaceable
130
The timeout is how long the server will wait for a
131
successful checker run until a client is considered
132
invalid - that is, ineligible to get the data this server
133
holds. By default Mandos will use 1 hour.
136
The <replaceable>TIME</replaceable> is specified as a
137
space-separated number of values, each of which is a
138
number and a one-character suffix. The suffix must be one
139
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
140
<quote>h</quote>, and <quote>w</quote> for days, seconds,
141
minutes, hours, and weeks, respectively. The values are
142
added together to give the total time value, so all of
143
<quote><literal>330s</literal></quote>,
144
<quote><literal>110s 110s 110s</literal></quote>, and
145
<quote><literal>5m 30s</literal></quote> will give a value
146
of five minutes and thirty seconds.
113
<term><literal>interval</literal></term>
152
<term><literal><varname>interval</varname></literal></term>
116
This option allows you to override the default interval
117
used between checkups for disconnected clients. By default
154
<synopsis><literal>interval = </literal><replaceable
158
How often to run the checker to confirm that a client is
159
still up. <emphasis>Note:</emphasis> a new checker will
160
not be started if an old one is still running. The server
161
will wait for a checker to complete until the above
162
<quote><varname>timeout</varname></quote> occurs, at which
163
time the client will be marked invalid, and any running
164
checker killed. The default interval is 5 minutes.
167
The format of <replaceable>TIME</replaceable> is the same
168
as for <varname>timeout</varname> above.
124
174
<term><literal>checker</literal></term>
176
<synopsis><literal>checker = </literal><replaceable
177
>COMMAND</replaceable>
127
180
This option allows you to override the default shell
128
command that the server will use to check up if the client
129
is still up. By default mandos will "fping -q -- %%(fqdn)s"
181
command that the server will use to check if the client is
182
still up. Any output of the command will be ignored, only
183
the exit code is checked: If the exit code of the command
184
is zero, the client is considered up. The command will be
185
run using <quote><command><filename>/bin/sh</filename>
186
<option>-c</option></command></quote>, so
187
<varname>PATH</varname> will be searched. The default
188
value for the checker command is <quote><literal
189
><command>fping</command> <option>-q</option> <option
190
>--</option> %(host)s</literal></quote>.
193
In addition to normal start time expansion, this option
194
will also be subject to runtime expansion; see <xref
195
linkend="expansion"/>.

The paramters for clients are:
146
201
<term><literal>fingerprint</literal></term>
203
<synopsis><literal>fingerprint = </literal><replaceable
204
>HEXSTRING</replaceable>
149
This option sets the openpgp fingerprint that identifies
150
the public certificate that clients authenticates themself
151
through gnutls. The string need to be in hex-decimal form.
207
This option sets the OpenPGP fingerprint that identifies
208
the public key that clients authenticate themselves with
209
through TLS. The string needs to be in hexidecimal form,
210
but spaces or upper/lower case are not significant.
157
216
<term><literal>secret</literal></term>
160
Base 64 encoded OpenPGP encrypted password encrypted by
161
the clients openpgp certificate.
218
<synopsis><literal>secret = </literal><replaceable
219
>BASE64_ENCODED_DATA</replaceable>
222
If present, this option must be set to a string of
223
base64-encoded binary data. It will be decoded and sent
224
to the client matching the above
225
<option>fingerprint</option>. This should, of course, be
226
OpenPGP encrypted data, decryptable only by the client.
227
The program <citerefentry><refentrytitle><command

230
<option>--password</option> option, be used to generate
234
Note: this value of this option will probably be very
235
long. A useful feature to avoid having unreadably-long
236
lines is that a line beginning with white space adds to
237
the value of the previous line, RFC 822-style.
240
If this option is not specified, the <option
241
>secfile</option> option is used instead, but one of them
242
<emphasis>must</emphasis> be present.

Base 64 encoded OpenPGP encrypted password encrypted by

sent to clients verbatim.

This option is only used, and <emphasis>must</emphasis> be

present, if <option>secret</option> is not specified.
267
<term><literal>host</literal></term>
269
<synopsis><literal>host = </literal><replaceable
270
>STRING</replaceable>
273
Host name for this client. This is not used by the server

checker. See the <option>checker</option> option.

mode is needed to track down an error of this kind.
