ftp

FTP (File Transfer Protocol) is the most widely used file-transfer mechanism. First defined in RFC 959, FTP runs on port 21. To use FTP to send or receive files, your systems must meet the following requirements:
• The client computer must have FTP client software.
• The user must have a user name and password on the remote system. In many cases, a user name of anonymous with no password is used.
• The remote system must be running an FTP daemon (Unix, VMS, etc.) or service (Windows NT/2000, etc.).
• Both systems must be running the TCP/IP protocol.
Figure 8.1 shows an FTP utility (WS_FTP Pro) that can transfer files between remote and local locations.
You can use FTP in either a command-line mode or a command-interpreter mode. The following options are available from the command line:
• -a—Use any local interface when binding data connections.
• -d—Enables debugging.
• -g—Disables file-name globbing (globbing permits the use of wildcard characters such as the asterisk and question mark in local file or path names).
• -i—Turns off interactive prompting during multiple file transfers.
• -n—Suppresses auto-login upon initial connection.
• -s:filename—Specifies a text file containing FTP commands; the commands will automatically run after FTP starts.
• -v—Suppresses the display of remote server responses.
• -w:buffersize—Overrides the default transfer buffer size of 4096K.
