Extended timeout is an added timeout that is given once
212
after a password has been sent successfully to a client.
213
The timeout is by default longer than the normal timeout,
214
and is used for handling the extra long downtime while a
215
machine is booting up. Time to take into consideration
216
when changing this value is file system checks and quota
217
checks. The default value is 15 minutes.
