The timeout is how long the server will wait (for either a

This option allows you to override the default shell

210
Extended timeout is an added timeout that is given once
211
after a password has been sent successfully to a client.
212
The timeout is by default longer than the normal timeout,
213
and is used for handling the extra long downtime while a
214
machine is booting up. Time to take into consideration
215
when changing this value is file system checks and quota
216
checks. The default value is 15 minutes.

This option sets the OpenPGP fingerprint that identifies

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

Mandos will use 5 minutes. See also the
