Number of Connections and Used Ports
The maximum number of concurrent connections is three. If a user attempts to connect to the FTP server
with which three connections have been established, the user cannot log in and fails in connection. The
default port for the FTP server is 21. There is no measure provided to change the port.
The control port time-out is set to 300 seconds. You need to re-connect to the server if you have left the
connection for 300 seconds or more after logging in. The data port time-out is 60 minutes. If a data trans-
mission takes more than 60 minutes, the connection is automatically disconnected.
