Answer 2

Don't forget that FTP Servers may still answer and let you know that your session has timed out.
You wouldn't get a SocketTimeoutException in this case:

com.enterprisedt.net.ftp.FTPException: Timeout. Pay attention.

Answer 5

You'll have to log in again.

Note you can call NoOp() to prevent the server timing you out.
