Ftp

ftp is the default client implementation of FTP (File Transfer Protocol) on FreeBSD systems. ftp is IPV6 aware, and is capable of creating, deleting, modifying and retrieving files to and from remote machines running an FTP server that supports these operations. It is also capable of retrieving files from an HTTP server.

These days, because the FTP protocol requires two ports (clumsy with firewalls), and cannot support encrypted transactions (it must be wrapped or tunneled in another protocol - also tricky because it requires two ports), many people prefer to use the slower but more secure sftp or rsync, which use the SSH subsystem called SFTP.
