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
