Two scenarios: connecting through a host server, vs. direct (SLIP or PPP)

In most cases, we use direct FTP to get files from a server to our workstation at home.
To use host-mediated FTP, you first log in to a server where you have an account (usually running Unix/Linux). You run FTP on that machine, open an FTP connection to an FTP server somewhere else, and transfer the files you want to the server where you have an account. When the file arrives at your server, you open an FTP or other file transfer connection to your own workstation, and transfer the file a second time. That finally gets it to your computer.
Direct FTP is obviously much more convenient! Why is there host-mediated FTP? It was necessary before people commonly had TCP/IP connections at home or in their offices, so it's mainly of historical interest. But for those of us who work professionally in the Internet business, it's important to know about this alternative, because it may be necessary in some circumstances. You never know!

You can use FTP to get to these archives (anonymous login, enter your email address as the password). There are limits on the number of simultaneos FTP sessions on ftp servers, so many of them will log you off after a certain period (say, 5 minutes) of inactivity.
