Description ■ Use the ftp server command to start FTP Server and enable FTP user logon. ■ Use the undo ftp server command to close FTP Server and disable FTP user logon. By default, FTP Server is shut down. Perform this command to easily start or shut down FTP Server, preventing the Switch from being attacked by an unknown user. Example Shut down FTP Server. system-view System View: return to User View with Ctrl+Z. [SW5500]undo ftp server ftp timeout Syntax ftp timeout minute undo ftp timeout View System view Parameter minute: Connection timeouts (measured in minutes), ranging from 1 to 35791; The default connection timeout time is 30 minutes. Description ■ Use the ftp timeout command to configure connection timeout interval. ■ Use the undo ftp timeout command to restore the default connection timeout interval. After a user logs on to an FTP Server and has established connection, if the connection is interrupted or cut abnormally by the user, FTP Server will still hold the connection. The connection timeout can avoid this problem. If the FTP server has no command interaction with a client for a specific period of time, it considers the connection to have failed and disconnects the client. Example Set the connection timeout to 36 minutes. system-view System View: return to User View with Ctrl+Z. [SW5500]ftp timeout 36 local-user Syntax local-user user_name
