In order to transfer files with FTP you need to have permission to use the remote machine. When FTP establishes a connection, it will ask you for a login name and password combination. If you have an account on the remote machine, use your login/password combination for that machine, just as if you were logging in via rlogin.

Machines that hold public domain software and other widely distributed files allow anonymous logins. Anonymous logins are like guest
accounts: anybody can use them, but there are limits to what you can do. Simply type ``anonymous'' for the login name and then type your e-mail address when you are prompted for the password. The remote system will not verify your e-mail address, so don't worry if you make a typing mistake; giving your full e-mail address is just a courtesy to the people who maintain the public information in case they want to gather statistics about how widely their files are distributed.
