This option allows you to override the default shell

Extended timeout is an added timeout that is given once
205
after a password has been sent successfully to a client.
206
The timeout is by default longer than the normal timeout,
207
and is used for handling the extra long downtime while a
208
machine is booting up. Time to take into consideration
209
when changing this value is file system checks and quota

checks. The default value is 15 minutes.
