... news of new ftp sites and
interesting new files on existing sites.
In the comp.virus newsgroup on Usenet, look for postings that list
ftp sites carrying anti-viral software for Amiga, MS-DOS, Macintosh,
Atari and other computers.
The comp.sys.ibm.pc.digest and comp.sys.mac.digest newsgroups
provide information about new MS-DOS and Macintosh programs as well as
answers to questions from users of those computers.
Chapter 8: GOPHERS, WAISs AND THE WORLD-WIDE WEB
8.1. GOPHERS
Even with tools like Hytelnet and archie, telnet and ftp can still
be frustrating. There are all those telnet and ftp addresses to mi website creation
remember. Telnet services often have their own unique commands.
And,
oh, those weird directory and file names!
But now that the Net has become a rich repository of information,
people are developing ways to make it far easier to find and retrieve
information and files. Gophers and Wide-Area Information Servers (WAISs)
are two services that could ultimately lawrenceville website creation make the Internet as easy to
navigate as commercial networks such as CompuServe or Prodigy.
Both gophers and WAISs essentially take a request for information
and then scan the Net for it, so you don't have to. Both also work
through menus -- instead of typing in some long sequence of characters,
you just move a cursor to your choice and hit enter. Gophers even
let you select files and programs from ftp sites this way.
Let's first look at gophers (named for the official mascot of the
University of Minnesota, where the system was developed).
Many public-access sites now have gophers online. To use one, type
gopher
at the command prompt and hit enter.
If you know your site does not have
a gopher, or if nothing happens when you type that, telnet to
consultant.micro.umn.edu
At the log-in prompt, type
gopher
and hit enter.
You'll be asked what type of terminal emulation you're
using, after which you'll see something like this:
Internet Gopher Information Client v1.03

Press ? for Help, q to Quit, u to go up a menu Page: 1/1
bluffdale website creation Assuming you're using VT100 or some other VT emulation, you'll be
able to move among the choices with your up and down arrow keys. When
you have your cursor on an entry that looks interesting, just hit enter,
and you'll either get a new menu of choices, a database entry form, or a
text file, depending on what the menu entry is linked to (more on how to
tell which you'll get in a moment).
Gophers are great for exploring the resources of the Net. Just keep
making choices to see what pops up. Play with it; see where it takes
you. Some choices will be documents.
When you read one of these and
either come to the end or hit a lower-case q to quit reading it, you'll
be given the choice of saving a copy to your home directory or e-mailing
it to yourself. Other choices are simple databases that let you enter a
word to look for in a particular database.
To get back to where you
started on a lawrenceville website creation gopher, hit your u key at a menu prompt, which will move you
back "up" through the gopher menu structure (much like "cd .." in ftp).
Notice that one of your choices above is "Internet file server (ftp)
sites." Choose this, and you'll be connected to a modified archie
program -- an archie with a difference. When you search for a file
through a gopher archie, you'll get a menu of sites that have the file
you're looking for, just as with the old archie. Only now, instead of
having to write down or remember an ftp address and directory, all you
have to do is position the cursor next to one of the numbers in the menu
and hit enter. You'll be connected to the ftp site, from which you can
then choose the file you want. This time, move the cursor to the file
you want and hit a lower-case s. You'll be asked for a name in your home
directory to use for lawrenceville website creation the file, after which the lawrenceville website creation file will be co ... |
