This option is <emphasis>optional</emphasis>.
111
The timeout is how long the server will wait for a
112
successful checker run until a client is considered
113
invalid - that is, ineligible to get the data this server
114
holds. By default Mandos will use 1 hour.
117
The <replaceable>TIME</replaceable> is specified as a
118
space-separated number of values, each of which is a
119
number and a one-character suffix. The suffix must be one
120
of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
121
<quote>h</quote>, and <quote>w</quote> for days, seconds,
122
minutes, hours, and weeks, respectively. The values are

This option overrides the default shell command that the

This option allows you to override the default shell

still up. Any output of the command will be ignored, only

run using <quote><command><filename>/bin/sh</filename>

182
170
<varname>PATH</varname> will be searched. The default

186
<command>mandos-keygen</command>, when generating output
187
to be inserted into this file, normally looks for an SSH
188
server on the Mandos client, and, if it find one, outputs
189
a <option>checker</option> option to check for the

This option is <emphasis>optional</emphasis>.
209
Extended timeout is an added timeout that is given once
210
after a password has been sent successfully to a client.
211
The timeout is by default longer than the normal timeout,
212
and is used for handling the extra long downtime while a
213
machine is booting up. Time to take into consideration
214
when changing this value is file system checks and quota
215
checks. The default value is 15 minutes.

191
This option sets the OpenPGP fingerprint that identifies
233
192
the public key that clients authenticate themselves with
234
through TLS. The string needs to be in hexadecimal form,
193
through TLS. The string needs to be in hexidecimal form,

The timeout is how long the server will wait, after a

successful checker run, until a client is disabled and not
344
allowed to get the data this server holds. By default
345
Mandos will use 5 minutes. See also the

The <replaceable>TIME</replaceable> is specified as an RFC
350
3339 duration; for example

one year, two months, three days, four hours, five
