The timeout is how long the server will wait for a
127
successful checker run until a client is considered
128
invalid - that is, ineligible to get the data this server
129
holds. By default Mandos will use 1 hour.
132
The <replaceable>TIME</replaceable> is specified as a
133
space-separated number of values, each of which is a
134
number and a one-character suffix. The suffix must be one
135
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
136
<quote>h</quote>, and <quote>w</quote> for days, seconds,
137
minutes, hours, and weeks, respectively. The values are
138
added together to give the total time value, so all of

140
<quote><literal>110s 110s 110s</literal></quote>, and

176
This option allows you to override the default shell
164
177
command that the server will use to check if the client is
165
still up. Any output of the command will be ignored, only
166
the exit code is checked: If the exit code of the command
167
is zero, the client is considered up. The command will be
168
run using <quote><command><filename>/bin/sh</filename>
169
<option>-c</option></command></quote>, so
170
<varname>PATH</varname> will be searched. The default
171
value for the checker command is <quote><literal

still up. The output of the command will be ignored, only
179
the exit code is checked. The command will be run using
180
<quote><command><filename>/bin/sh</filename>

<emphasis>required</emphasis>.
250
Similar to the <option>secret</option>, except the secret

will be sent to clients verbatim.

>BASE64_ENCODED_DATA</replaceable>

216
If present, this option must be set to a string of
274
217
base64-encoded binary data. It will be decoded and sent
275
218
to the client matching the above
276
219
<option>fingerprint</option>. This should, of course, be
277
220
OpenPGP encrypted data, decryptable only by the client.
278
The program <citerefentry><refentrytitle><command
279
>mandos-keygen</command></refentrytitle><manvolnum
280
>8</manvolnum></citerefentry> can, using its
281
<option>--password</option> option, be used to generate
285
Note: this value of this option will probably be very
286
long. A useful feature to avoid having unreadably-long
287
lines is that a line beginning with white space adds to
288
the value of the previous line, RFC 822-style.

298
This option is <emphasis>optional</emphasis>.
301
The timeout is how long the server will wait (for either a
302
successful checker run or a client receiving its secret)
303
until a client is disabled and not allowed to get the data
304
this server holds. By default Mandos will use 1 hour.
307
The <replaceable>TIME</replaceable> is specified as a
308
space-separated number of values, each of which is a
309
number and a one-character suffix. The suffix must be one
310
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
311
<quote>h</quote>, and <quote>w</quote> for days, seconds,
312
minutes, hours, and weeks, respectively. The values are
313
added together to give the total time value, so all of
314
<quote><literal>330s</literal></quote>,
315
<quote><literal>110s 110s 110s</literal></quote>, and
316
<quote><literal>5m 30s</literal></quote> will give a value
317
of five minutes and thirty seconds.

227
Note: this value of this option will probably run over
228
many lines, and will then have to use the fact that a line
229
beginning with white space adds to the value of the
230
previous line, RFC 822-style.
