<title>DESCRIPTION</title>
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
61
The file &CONFPATH; is a configuration file for <citerefentry
62
><refentrytitle>mandos</refentrytitle>
63
<manvolnum>8</manvolnum></citerefentry>, read by it at startup.
64
The file needs to list all clients that should be able to use
65
the service. All clients listed will be regarded as valid, even
66
if a client was declared invalid in a previous run of the
70
The format starts with a <literal>[<replaceable>section
71
header</replaceable>]</literal> which is either
72
<literal>[DEFAULT]</literal> or <literal>[<replaceable>client
73
name</replaceable>]</literal>. The <replaceable>client
74
name</replaceable> can be anything, and is not tied to a host
75
name. Following the section header is any number of
76
<quote><varname><replaceable>option</replaceable
77
></varname>=<replaceable>value</replaceable></quote> entries,
78
with continuations in the style of RFC 822. <quote><varname
79
><replaceable>option</replaceable></varname>: <replaceable
80
>value</replaceable></quote> is also accepted. Note that
81
leading whitespace is removed from values. Values can contain
82
format strings which refer to other values in the same section,
83
or values in the <quote>DEFAULT</quote> section (see <xref
84
linkend="expansion"/>). Lines beginning with <quote>#</quote>
85
or <quote>;</quote> are ignored and may be used to provide
94

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

<refsect1 id="options">
91
<title>OPTIONS</title>
93
<emphasis>Note:</emphasis> all option values are subject to
94
start time expansion, see <xref linkend="expansion"/>.
97
Unknown options are ignored. The used options are as follows:
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>
103
<term><option>timeout<literal> = </literal><replaceable
104
>TIME</replaceable></option></term>
107
This option is <emphasis>optional</emphasis>.
110
The timeout is how long the server will wait for a
111
successful checker run until a client is considered
112
invalid - that is, ineligible to get the data this server
113
holds. By default Mandos will use 1 hour.
116
The <replaceable>TIME</replaceable> is specified as a
117
space-separated number of values, each of which is a
118
number and a one-character suffix. The suffix must be one
119
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
120
<quote>h</quote>, and <quote>w</quote> for days, seconds,
121
minutes, hours, and weeks, respectively. The values are
122
added together to give the total time value, so all of
123
<quote><literal>330s</literal></quote>,
124
<quote><literal>110s 110s 110s</literal></quote>, and
125
<quote><literal>5m 30s</literal></quote> will give a value
126
of five minutes and thirty seconds.
132
<term><option>interval<literal> = </literal><replaceable
133
>TIME</replaceable></option></term>
136
This option is <emphasis>optional</emphasis>.
139
How often to run the checker to confirm that a client is
140
still up. <emphasis>Note:</emphasis> a new checker will
141
not be started if an old one is still running. The server
142
will wait for a checker to complete until the above
143
<quote><varname>timeout</varname></quote> occurs, at which
144
time the client will be marked invalid, and any running
145
checker killed. The default interval is 5 minutes.
148
The format of <replaceable>TIME</replaceable> is the same
149
as for <varname>timeout</varname> above.
155
<term><option>checker<literal> = </literal><replaceable
156
>COMMAND</replaceable></option></term>
159
This option is <emphasis>optional</emphasis>.
127
162
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"

The paramters for clients are:
146
<term><literal>fingerprint</literal></term>
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.
157
<term><literal>secret</literal></term>
160
Base 64 encoded OpenPGP encrypted password encrypted by
161
the clients openpgp certificate.
167
<term><literal>secfile</literal></term>
170
Base 64 encoded OpenPGP encrypted password encrypted by
171
the clients openpgp certificate as a binary file.
177
<term><literal>fqdn</literal></term>
180
FQDN, that can be used in for checking that the client is up.

command that the server will use to check if the client is
164
still up. Any output of the command will be ignored, only
165
the exit code is checked: If the exit code of the command
166
is zero, the client is considered up. The command will be
167
run using <quote><command><filename>/bin/sh</filename>
168
<option>-c</option></command></quote>, so
169
<varname>PATH</varname> will be searched. The default
170
value for the checker command is <quote><literal
171
><command>fping</command> <option>-q</option> <option
172
>--</option> %(host)s</literal></quote>.
175
In addition to normal start time expansion, this option
176
will also be subject to runtime expansion; see <xref
177
linkend="expansion"/>.
183
<term><option>fingerprint<literal> = </literal
184
><replaceable>HEXSTRING</replaceable></option></term>
187
This option is <emphasis>required</emphasis>.
190
This option sets the OpenPGP fingerprint that identifies
191
the public key that clients authenticate themselves with
192
through TLS. The string needs to be in hexidecimal form,
193
but spaces or upper/lower case are not significant.
199
<term><option>secret<literal> = </literal><replaceable
200
>BASE64_ENCODED_DATA</replaceable></option></term>
203
If this option is not specified, the <option
204
>secfile</option> option is <emphasis>required</emphasis>
208
If present, this option must be set to a string of
209
base64-encoded binary data. It will be decoded and sent
210
to the client matching the above
211
<option>fingerprint</option>. This should, of course, be
212
OpenPGP encrypted data, decryptable only by the client.
213
The program <citerefentry><refentrytitle><command
214
>mandos-keygen</command></refentrytitle><manvolnum
215
>8</manvolnum></citerefentry> can, using its
216
<option>--password</option> option, be used to generate
220
Note: this value of this option will probably be very
221
long. A useful feature to avoid having unreadably-long
222
lines is that a line beginning with white space adds to
223
the value of the previous line, RFC 822-style.
229
<term><option>secfile<literal> = </literal><replaceable
230
>FILENAME</replaceable></option></term>
233
This option is only used if <option>secret</option> is not
234
specified, in which case this option is
235
<emphasis>required</emphasis>.
238
Similar to the <option>secret</option>, except the secret
239
data is in an external file. The contents of the file
240
should <emphasis>not</emphasis> be base64-encoded, but
241
will be sent to clients verbatim.
247
<term><option><literal>host = </literal><replaceable
248
>STRING</replaceable></option></term>
251
This option is <emphasis>optional</emphasis>, but highly
252
<emphasis>recommended</emphasis> unless the
253
<option>checker</option> option is modified to a
254
non-standard value without <quote>%(host)s</quote> in it.
257
Host name for this client. This is not used by the server
258
directly, but can be, and is by default, used by the
259
checker. See the <option>checker</option> option.

Note that this means that, in order to include an actual

percent character (<quote>%</quote>) in a
310
<varname>checker</varname> option, <emphasis>four</emphasis>
311
percent characters in a row (<quote>%%%%</quote>) must be

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

mode is needed to expose an error of this kind.
