By default, ftp use ASCII mode for data transfer. Because the shipment without encryption, then the username, password, the data transferred, and that the command can be sent in by sniffing people using the protocol analyzer (Sniffer). The solution is used by using SFTP (SSH FTP) which is based on FTP or SSH using FTPS (FTP over SSL) so that the data is sent first encrypted (dikodekan).

FTP usually uses two ports, namely ports 20 and 21 and run exclusively through the TCP. Listen FTP server on port 21 for incoming connection from the FTP client.
