According to the specification of URL formats, RFC 1738, an FTP URL is of the form:
so that some or all of the parts user
/path may be excluded.
The components obey the following rules:
|a user name (user id) on the host|
|the password corresponding to the user name; note: if the user and password field in a URL contains character
|the fully qualified domain name of a network host, or its IP address|
|the port number to connect to; it omitted, defaults to 21|
|path specification of the form
The host is usually the external IP address that your ISP has assigned to you. Cerberus FTP Server will attempt to detect it and display is as the WAN IP Address on startup.
Security Note: You should generally avoid using FTP URL sytax for anything other than anonymous FTP access. Including a password is a security risk. On most browsers, it will be visible as you type it, and it will be retained by your history file.
