Mac users should get a program called uutool, which can be found

websites design Think twice before sending somebody a web design package giant file. Although large
sites connected directly to the Internet can probably handle mega-files,
many web design manchester smaller systems cannot. Some commercial systems, such as CompuServe
and MCIMail, limit the size of mail messages their users can receive.
Fidonet doesn't even allow encoded messages. In general, a file size of
30,000 or so bytes is a safe upper limit for non-Internet systems.
9.4 GETTING FTP FILES VIA E-MAIL
To help people without ftp access, a number of ftp sites have set up
mail servers (also known as archive servers) web design manchester that allow you to get files
via e-mail. You send a request to one of these machines and they send
back the file you want. As with ftp, you'll be able to find everything
from historical documents to software (but please note that if you do
have access to ftp, that method is always quicker and ties up fewer
resources than using e-mail).
Some interesting or useful mail servers include:
mail-server@rtfm.mit.edu Files of "frequently asked questions"
related to Usenet; state-by-state lists of U.S. representatives and
Senators and their addresses and office phone numbers.
archive-server@eff.org Information about the Electronic Frontier
Foundation; documents about legal issues on the Net.
archive-server@cs.widener.edu Back copies of the Computer
Underground Digest and every possible fact you could want to know about
"The Simpsons."
netlib@uunet.uu.net Programs for many types of personal computers;
archives of past postings from many Usenet newsgroups.
archive-server@ames.arc.nasa.gov Space-related text and graphics
(GIF-format) files.
service@nic.ddn.mil Detailed information about Internet.
Most mail servers work pretty much the same -- you send an e-mail
message that tells them what file you want and how you want it sent to
you. The most important command is "send," which tells the computer you
want it to send you a particular file.
First, though, you'll need to know where the mail server stores
that file, because you have to tell it which directory or sub-
directory it's in. There are a couple of ways to do this. You can
send an e-mail message to the web design package archive-server that consists of one
line:
index
The server will then send you a web design package directory listing of its main, or
root directory. You'll then have to send a second message to the
archive server with one line:
websites design index directory/subdirectory
where directory/subdirectory is the directory path for which you want a
listing. An alternative is to send an e-mail message to our old friend
archie, which should send you back the file's exact location on the
archive-server (along with similar listings for all the other sites that
may have the file, however)
Once you have the file name and its directory path, compose a
message to the archive server web design package like this:
send directory/subdirectory/file
Send off the message and, anywhere from a few minutes to a couple
of days later, you'll find a new message in your mailbox: a copy of the
file you requested.
The exact time it will take a file to get to you
depends on a variety of factors, including how many requests are in line
before yours (mail servers can only process so many requests at a time)
and the state of the connections between the server and you.
Seems simple enough. It gets a little more complicated when you
request a web design package program rather than a document. Programs or other files that
contain unusual characters or lines longer than 130 characters (graphics
files, for example) require special processing by the mail server to
ensure they are transmitted via e-mail. Then you'll have to run them
through at least one converter program to put them in a form you can
actually use.
To ensure that a program or other web design package "non-mailable" file
actually gets to you, include another line in your e-mail message to the
server:
encoder
This converts the file into an encoded form. To decode it, you'll
first have to transfer the file message into a file in your home
directory.
One further complication comes when you request a particularly
long file. Many Net sites can only handle so much mail at a time. To
make sure you get the entire file, tell the mail server to break it up
into smaller pieces, with another line in your e-mail request like
this:
size 100000
This gives the mail server the maximum size, in bytes, of each
file segment. This particular size ... |
