Today we're going to practice on some small files that shouldn't overload anyone's account. We're also going to practice on some things that are relatively trivial. Please don't think that's the end of items out there to ftp. There's everything from the sublime to the ridiculous. I've got us some places to practice ftp.
Some ftp sites get thousands of requests per day.
It's considered good form to use ftp facilities between 6pm and 6am in order to cut down on the daytime traffic on these servers. Anonymous ftp sites allow anyone to access information that they make available to the public. You may logon to a server that's doing lots more than anonymous ftp. What these servers are letting you into are public areas. Ftp can also be used to transfer files between computers on which you have accounts.
