The FTP application you use to connect to the server is a client, and your client software can connect to an FTP server running on port 21 on a remote machine. FTP is included on most of today's operating systems. FTP creates both a control and a data connection in order to transfer files. The control connection is based on telnet and is used to negotiate the parameters for the data transfer. This is called an active FTP connection. You can get a list of the commands by typing '?

No wildcards! Can only get one file at a time. The list of files should be separated by spaces. Interactive prompting occurs during multiple file transfers to allow the user to selectively retrieve or store files. If prompting is turned off, any mget or mput will transfer all files, and any mdelete will delete all files.
