Some systems are open to the public; anyone can get on and grab files that the system administrator has decided should be publicly accessible.

This type of access is known as anonymous ftp because you don t need a unique login name to get onto the computer; you simply log in as anonymous and you normally enter your email address for the password. If you are working at the UNIX command line, as many unfortunate people still do, you have to type this information. However, the rest of you are using a program that will enter this information for you.

. What if you know the file you want, but you have no idea where to look for it A quick way to track down a file is using Archie. You ll learn about Archie later in this chapter..

Different Flavours Of FTP FTP was originally a comm and-line program in which you had to type commands at a prompt and press the Enter key. Information would then scroll past on your screen, perhaps too fast for you to read (unless you knew the secret command to make it slow down or stop). You d have to read this information and then type another command.

Although UNIX geeks got some sort of strange masochistic pleasure out of that sort of thing, real people found early FTP to be a painful experience and most people avoided it. However, for about seven or eight years now there have been graphical FTP programs, Windows and Macintosh programs using familiar point-and-click (and even drag-and-drop) tools. Most of these graphical FTP programs enable you to see lists of files and use your mouse to carry out the operations.

Using FTP with these systems was a pleasure; all of a sudden FTP became easy. Of the many graphical FTP programs available, the best I ve seen are CuteFTP and WS_FTP (Windows shareware programs) and Fetch and NetFinder (Macintosh shareware programs); see Appendix C, All The Software You ll Ever Need for information about finding all these programs. Another FTP program is Anarchie, a shareware program that melds FTP with Archie (which I ll mention later).

But many others are available, particularly for Windows.. Part 2 There s Plenty More Finally, FTP has been inc .net framework barcode 128 orporated into Web browsers. You can now go to an FTP site using your Web browser and usually without a special FTP program.

Because the FTP site appears as a document with links in it, you can click a link to view the contents of a directory, to read a text file, or to transfer a computer file to your computer. We ll look first at running FTP sessions with a Web browser for a couple of reasons. First, it s a very easy way to work with FTP.

Second, you probably already have a Web browser. However, there are some very good reasons for getting hold of a true FTP program; I ll discuss this issue towards the end of this chapter..

Hitting The FTP Trail To work through an FTP ex Code 128 Code Set C for .NET ample, go to ftp://sunsite.org.

uk/. This is one of the best and fastest FTP archives in the UK. (If you prefer to visit another FTP site, you can follow along and do so; the principles are the same.

) You can find a list of FTP sites to play with by visiting http://tile.net/ftp/ and choosing either Country or Site Name..

his Out kT Che c What s In A Name Take a minute to analyse .NET Code-128 a site name. First there s the ftp:// part.

This simply tells your browser that you want to go to an FTP site. Then there s the FTP site name (or host name): sunsite.org.

uk. It identifies the computer that contains the files you are after. That might be followed by a directory name.

I haven t given you a directory name in this example, but I could have told you to go to sunsite.org.uk/pub/computing.

The /pub/computing bit tells the browser which directory it must change to in order to find the files you want.. To start, open your Web b rowser. Click inside the Address text box, type ftp://sunsite.org.

uk (or ftp:// and the address of another site you want to visit) and press Enter. Actually, in most browsers these days, you can omit the ftp:// as long as the site name begins with ftp. For example, if you were visiting another useful UK site, ftp.

demon.co.uk, instead of typing out ftp://ftp.

demon.co.uk, you could get away with typing only ftp.

demon.co.uk.

In a few moments, with luck, you ll see something like the screen shown in the following figure. Without luck, you ll probably get a message telling you that you cannot connect to the FTP site. If that happens, check to see if you typed the name correctly.

If you did, you ll have to wait and try again later; the site may be closed, or it may be very busy..
