* Nothing happens when you try to connect to a telnet site.
The site could be down for maintenance or problems.
* You get a "host unavailable" message. The telnet site is down
for email friend some reason.
Try again later.
* You get a "host unknown" message.
Check your spelling of the site name.
* You type in a password on a telnet site that requires one, and
you get a "login incorrect" message.
Try logging in again. If you get the message again, hit your
control and ] keys at the same time to disengage and return to your host
system.
* You can't seem to disconnect from a telnet site.
Use control-] to disengage and return to your host system.
6.8 FYI
The Usenet newsgroups alt.internet.services and alt.bbs.internet
can provide pointers to new telnet systems. Scott Yanoff periodically
posts his "Updated Internet Services List" in the former. The
alt.bbs.internet newsgroup is also where you'll find Aydin Edguer's
compendium of FAQs related to Internet bulletin-board email friend systems.
Peter Scott, who maintains the Hytelnet database, runs a
mailing list about new telnet services and changes in existing ones.
To get on the list, send him a note at scott@sklib.usask.ca.
Gleason Sackman maintains another mailing list dedicated to new
Internet services and news about the new uses to which the Net is being
put. To subscribe, send a message to listserv@internic.net. Leave the

Chapter 7: FTP
7.1 TONS OF FILES
Hundreds of systems connected to Internet have file libraries, or
archives, accessible to the public. Much of this consists of free or low-
cost email friend shareware programs for virtually every make of computer. If you
want a different communications program for your IBM, or feel like
playing a new game on email friend your Amiga, you'll be able to get it from the Net.
But there are also libraries of documents as well. If you
want a copy of a recent U.S. Supreme Court decision, you can find it on
the Net. Copies of historical documents, from the Magna Carta to the
Declaration of Independence are also yours for the asking, along with a
translation of a telegram from Lenin ordering the execution of
rebellious peasants. You can also find song lyrics, poems, even
summaries of every "Lost in Space" episode ever made. You can also find
extensive files detailing everything you could ever possibly want to know
about the Net itself. First you'll see how to get email spain these files; then
we'll show you where they're kept.
The commonest way to get these files is through the file transfer
protocol, or ftp.
As with telnet, not all systems that connect to the
Net have access to ftp. However, if your system is one of these, you'll
be able to get many of these files through e-mail (see the next chapter). account email new set up
Starting ftp is as easy as using telnet.
At your host system's command
line, type
ftp site.name
and hit enter, email friend where "site.name" is the address of the ftp site you want
to reach. One major difference between telnet and ftp is that it is
considered bad form to connect to most ftp sites during their business
hours (generally 6 a.m. to 6 p.m. local time). email information This is because
transferring files across the network takes up considerable computing
power, which during the day is likely to be needed for whatever the
computer's main function is. There are some ftp sites that are
accessible to the public 24 hours a day, though. You'll find these noted
in the list of ftp sites in section 7.6
7.2 YOUR FRIEND ARCHIE
How do you find a file you want, though?
Until a few years ago, this could be quite the pain -- there was
no master directory to tell you where a given file might be stored on
the Net.
Who'd want to slog through hundreds of file libraries looking
for something?
Alan Emtage, Bill Heelan and Peter Deutsch, students at McGill
University in Montreal, asked the same question.
Unlike the weather,
though, they did something about it.
They created a database system, called archie, that would
periodically call up file libraries and basically find out what they had
available. In turn, anybody could dial into archie, type in a file name,
and see where on the Net it was available. Archie currently catalogs
close to 1,000 file libraries around the world.
