MicroImages' FTP Server
FTP stands for "File Transfer
Protocol." Simply stated, FTP is the process you use to download or
Anyone may connect to the MicroImages FTP server to download software such as TNTmips or MI/X, or get any of
our selection of Datasets
prepared for public use in the TNT
products. Clients may connect to MicroImages' FTP server to upload files
for the MicroImages software support team.
There are several ways to engage
an FTP session with MicroImages' FTP server in order to upload or download
Before we cover each of these methods please note the
- You may download (get) files from the MicroImages
FTP server using any of the above methods.
- If you are a client and want to upload (put) files
by command-line FTP, you need to first create a zip file containing your data and upload the zip file to the /pub/incoming
directory. Do not create a subdirectory — if you do it will be empty due to security restrictions.
After uploading the zip file notify us via
email to MicroImages' technical support and include the name of the file.
Command-Line FTP for Beginners
Although command-line FTP is the hardest method to use, it is
ubiquitous to the UNIX world and nearly so to the PC platform. This method is
seldom seen implemented for the MacOS directly, unless a connection to a remote
host is made first. Under UNIX, you may just type
ftp at the
command prompt to start the program that UNIX uses to transfer files. The same
will probably be true if you are running some version of Windows.
A sample "anonymous" FTP session
To initiate a connection to our FTP server, type
After the normal waiting period (allow for Internet traffic)
you should see something in the form of:
Connected to ftp.microimages.com.
220-MicroImages FTP Server
220-All transfers are logged.
220 tnt FTP server (Version wu-2.4(2) Thu Dec 1 08:30:25 CST 1994) ready.
Name prompt, type
and hit <return>, unless you have been directed otherwise by MicroImages.
Then the server will prompt you for a password. Enter your entire email
address as the password.
331 Guest login ok, send your complete e-mail address as password.
After you enter your complete email address and hitting the
<return> key, (if login was successful) the computer displays:
230-Welcome to the MicroImages FTP server.
230-If you are expecting something from us, look in /pub/outgoing
230-If you're sending us a file, cd to /pub/incoming for instructions
230-All transfers are logged.
230 Guest login ok, access restrictions apply.
The last line on the screen is the new
prompt. You are now logged in anonymously to MicroImages' FTP server in
Lincoln, Nebraska USA. From here you may change directories, browse directories
and download or upload files. If you are interested in transfering files, the
first thing that you should do is type
cd pub because all of the
things that will be of interest to the FTP user are found below the /pub
directory. If you type
pwd the server tells you what directory you
are in at any time. Typing
ls will give you a listing of files in
the current directory.
The Command-Line: Basic steps
In a nutshell, here are some of the basic steps you will take
to transfer a file to/from MicroImages.
- Connect to the server and login anonymously
- Navigation Commands
To see what's in the current directory.
To change your current directory to dirname.
To tell what directory you're in now. (Think "print working
- File Transfer Commands
Switch to binary file transfer mode. Transferring binary files in ASCII
text tranfer mode will botch them. You can always type
to make sure that you're in binary mode.
Switch to ASCII text transfer mode. Do this only if you're sure that
you're what you're transferring is a plain text file. The ASCII
mode will alter the file as it transfers between the two machines so
that newline, linefeed, and carriage return characters are correct on
the destination machine. If you're not sure what kind of file you're
dealing with, just use the binary mode to transfer files.
get remote_filename local_filename
Download a file to your computer.
remote_filename refers to
a file already existing on the server,
the name under which you would like to save
on your computer.
If you don't specify
local_filename, the new copy on your
machine has the same name as
remote_filename. if you don't
want to explicitly name the file you're downloading.
put local_filename remote_filename
Upload a file to the server.
local_filename refers to a
file already existing on your computer, and
is the name under which you would like to save
on the server. If you don't specify
new copy on the server has the same name as
This command toggles on/off the "interactive mode", i.e. if
you want to transfer multiple files with one command and you're in
interactive mode, ftp will ask you to confirm each transfer. If you want
to transfer multiple files with one command and you're not in
interactive mode, the files will be quietly transferred without ftp
asking you to confirm each transfer. This is most useful in conjunction
with the commands shown below.
mget filename_1 filename_2 ... filename_n
Download all files specified. If you want to download all the files in
the current working directory, type
mget *. The
is called a wildcard character and matches each file.
mput filename_1 filename_2 ... filename_n
Upload all files specified. If you want to upload all the files in the
current working directory, type
mput *. The
is called a wildcard character and matches each file.

Basic information about what
- Closing, Quitting, Reconnecting
To close the connection with the host
To open/reconnect to the host hostname.
To quit the FTP application. Typing
bye while still
connecting is a fast way to close your connection and quit the FTP
application at the same time.
- Please be sure to close your connection with the FTP
server when you have finished. This frees up unused resources so that
everyone can have better service.
Graphical User Interface FTP programs
Graphical interface programs are largely self-explanatory.
Whether you're uploading or downloading files, you first need to make a
connection. Your GUI FTP program will probably give you several fields to fill
in, such as location, username, password, and destination directory. For
as the user name, and your full email address as the password. If you
know the name of the directory that the files are in, you can specify that as
well, in order to save time. Most GUI FTP programs allow point-and-click
navigation of directories, which may make you wait for a new list each time you
select to change a directory. The common way to download a file is to select it
with the mouse, and click a button to initiate the download.
FTP by Internet Browser
If you want to upload a file to MicroImages using your
browser, use this form.
Downloading files with a browser is as straightforward as
following a link in an HTML document. If the URL refers to a file to download,
you can download it by clicking on its hyperlink. Sometimes with certain
browsers, however, when you follow an FTP link to attempt to download a file to
your hard drive, the browser attempts to display the file in its window. This
can happen if the file is a text file or if the file is in a binary format that
the browser doesn't recognize. Should this happen, it is usually best to stop
the browser from attempting to display the file (especially if it is a binary
file) and to use whatever feature of the browser that allows you to "Save
a link as" a file. (More
When downloading via Internet browser, you don't need to
login, or worry about what mode the transfer is using--the browser handles
these issues transparently. Here is the URL to browse MicroImages' FTP server
