The timeout is how long the server will wait for a

successful checker run until a client is considered

This option overrides the default shell command that the

output of the command will be ignored, only the exit code

client is considered up. The command will be run using

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

command is <quote><literal><command>fping</command>

<command>mandos-keygen</command>, when generating output

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

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

successful checker run, until a client is disabled and not
343
allowed to get the data this server holds. By default

Mandos will use 5 minutes. See also the
