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

machine is booting up. Time to take into consideration
215
when changing this value is file system checks and quota
