to another mail folder,
not your home directory).
In all three cases, exit the mail program to return to your host
system's command line. Because the file has been encoded for html tutorial mail
delivery, you now have to run a decoder. At the command line, type
uudecode file.name
where file.name is the file you created while in mail. Uudecode will
create a new, uncompressed binary file. In some cases, you may have to
run it through some other programs (for example, if it is in "tar" form),
but generally it should now be ready for you to download to your own
computer (on which you might then have to run a de-compressor program
such as PKXZIP).
9.3 FILES TO NON-INTERNET SITES
What if your friend only connects with a non-Unix system, such as
CompuServe or MCIMail? There are programs available for MS-DOS, Apple
and Amiga computers that will encode and decode files.
Of course, since
you can't send one of these programs to your friend via e-mail (how would
she un-encode it?), you'll have to mail (the old-fashioned way) or give
her a diskette with the program on it first. Then, she can get the file
by e-mail and go through the above process (only on her own computer) to
get a usable file. Remember to give her an encoder html tutorial program as well, if
she wants to send you files in return.
For MS-DOS machines, you'll want to get uunecode.com and
uudecode.com. Both can be found through anonymous ftp at
wuarchive.wustl.edu in the /mirrors/msdos/starter directory. The MS-
DOS version is as easy to use as the Unix one: Just type
uudecode filename.ext
and hit enter.
Mac users should get a program called uutool, which can be found
in the info-mac/util directory on sumex-aim.stanford.edu.
Think twice before sending somebody a giant file. Although large
sites connected directly to the Internet can probably handle mega-files,
many 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) 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from historical documents to software php tutorial (but please note that if you do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.
html tutorial 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 php tutorial 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 archive-server that consists of one
line:
index
The server will then html tutorial send you a directory listing of its main, or
root directory. You'll then have to send a second message to the
archive server with one line:
index directory/subdirectory
where that is the directory or 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 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 reques ... |
