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

105
>TIME</replaceable></option></term>
116
<term><literal><varname>timeout</varname></literal></term>
108
This option is <emphasis>optional</emphasis>.
111
The timeout is how long the server will wait (for either a
112
successful checker run or a client receiving its secret)
113
until a client is considered invalid - that is, ineligible
114
to get the data this server holds. By default Mandos will

122
The timeout is how long the server will wait for a
123
successful checker run until a client is considered
124
invalid - that is, ineligible to get the data this server
125
holds. By default Mandos will use 1 hour.
118
128
The <replaceable>TIME</replaceable> is specified as a
151
160
as for <varname>timeout</varname> above.
157
<term><option>checker<literal> = </literal><replaceable
158
>COMMAND</replaceable></option></term>
166
<term><literal>checker</literal></term>
161
This option is <emphasis>optional</emphasis>.
164
169
This option allows you to override the default shell
165
command that the server will use to check if the client is
166
still up. Any output of the command will be ignored, only
167
the exit code is checked: If the exit code of the command
168
is zero, the client is considered up. The command will be
169
run using <quote><command><filename>/bin/sh</filename>
170
<option>-c</option></command></quote>, so
171
<varname>PATH</varname> will be searched. The default
172
value for the checker command is <quote><literal
173
><command>fping</command> <option>-q</option> <option
174
>--</option> %%(host)s</literal></quote>.
177
In addition to normal start time expansion, this option
178
will also be subject to runtime expansion; see <xref
179
linkend="expansion"/>.
185
<term><option>fingerprint<literal> = </literal
186
><replaceable>HEXSTRING</replaceable></option></term>
189
This option is <emphasis>required</emphasis>.
192
This option sets the OpenPGP fingerprint that identifies
193
the public key that clients authenticate themselves with
194
through TLS. The string needs to be in hexidecimal form,
195
but spaces or upper/lower case are not significant.
201
<term><option>secret<literal> = </literal><replaceable
202
>BASE64_ENCODED_DATA</replaceable></option></term>
205
If this option is not specified, the <option
206
>secfile</option> option is <emphasis>required</emphasis>
210
If present, this option must be set to a string of
211
base64-encoded binary data. It will be decoded and sent
212
to the client matching the above
213
<option>fingerprint</option>. This should, of course, be
214
OpenPGP encrypted data, decryptable only by the client.
215
The program <citerefentry><refentrytitle><command
216
>mandos-keygen</command></refentrytitle><manvolnum
217
>8</manvolnum></citerefentry> can, using its
218
<option>--password</option> option, be used to generate
222
Note: this value of this option will probably be very
223
long. A useful feature to avoid having unreadably-long
224
lines is that a line beginning with white space adds to
225
the value of the previous line, RFC 822-style.
231
<term><option>secfile<literal> = </literal><replaceable
232
>FILENAME</replaceable></option></term>
235
This option is only used if <option>secret</option> is not
236
specified, in which case this option is
237
<emphasis>required</emphasis>.
240
Similar to the <option>secret</option>, except the secret
241
data is in an external file. The contents of the file
242
should <emphasis>not</emphasis> be base64-encoded, but
243
will be sent to clients verbatim.

File names of the form <filename>~user/foo/bar</filename>

non-standard value without <quote>%%(host)s</quote> in it.
