Anonymous FTP Server General Information

This file contains information about the general structure, as well as
information on how to obtain files and documentation from the FTP server.
NCSA software and documentation can also be obtained through the the U.S.
Mail. Instructions are included for using this method as well.

Information about the Software Tools Group and NCSA software can be found in
the README.BROCHURE file. The complete hierarchy of the FTP server can be
found in the INDEX file at the root level of the server.




Most NCSA Software is released into the public domain. That is, for these
programs, the public domain has all rights for future licensing, resale,
and publication of available packages. If you are connected to Internet
(NSFNET, ARPANET, MILNET, etc) you may download NCSA software and documentation and source code if it is available, at no charge from the anonymous file
transfer protocol (FTP) server at NCSA where you got this file. The procedure
you should follow to do so is presented below. If you have any questions
regarding this procedure or whether you are connected to Internet, consult your local system administration or network expert.

1. Log on to a host at your site that is connected to the Internet and is
running software supporting the FTP command.

2. Invoke FTP on most systems by entering the Internet address of the server.
Type the following at the shell (usually "%") prompt:

% ftp
% ftp

3. Log in by entering anonymous for the name.

4. Enter your local email address ([email protected]) for the password.

5. Enter the following at the "ftp>" prompt to copy a file from the server to
your local host:

ftp> get filename

where "filename" is the name of the file you want a copy of. For example,
to get a copy of this file from the server enter:


To get a copy of our software brochure, enter:


NOTE: Some of the filenames on the server are rather long to aid in
identification. Some operating systems may have problems with names
this long. To change the name the file will have on your local
machine type the following at the "ftp>" prompt ("remoteName" is the
name of the file on the server and "localName" is the name you want
the file to have on your local machine):

ftp> get remoteName localName



6. For files that are not text files (almost everything else) you will need to
specify that you want to transfer binary files. Do this by typing the
following at the "ftp>" prompt:

ftp> type binary

You can now use the "get" command to download binary files. To switch back
to ASCII text transfers type:

ftp> type ascii

7. The "ls" and "cd" commands can be used at the "ftp>" prompt to list and
change directories as in the shell.

8. Enter "quit" to exit FTP and return to your local host.



A tape archive of the FTP server may also be obtained from NCSA if your site
does not support FTP, or is not connected to the Internet. The tapes are
available in the following formats:

8mm Exabyte tape
DC600 cartridge tape
1600 bpi 9 track reel tape
6250 bpi 9 track reel tape

To obtain an order form, send your request to the following address:

The Software Tools Group here at NCSA is very virus-conscious. We routinely
check our machines for viruses and recommend that you do so also. For the
Macintoshes we use Disinfectant. You can obtain a copy of Disinfectant from
the Mac directory.

All Mac files on the server that were created by the Software Tools Group have
been checked for viruses with Disinfectant. Software in "Mac/contributions"
directory is NOT checked for viruses. Be sure to check any software downloaded
from the "Mac/contributions" directory before using it.




The FTP server is organized as specified below:

/Mac Macintosh software
/PC IBM PC software
/UNIX Software for machines running UNIX or equivalent OS
/HDF Hierarchical Data Format applications and tools
/Collab Collaborative software tools
/Samples Samples that can be used with most of NCSA software tools
/Documentation Currently being constructed, check each application's
directory for documentation
/misc Miscellaneous documentation and software
/incoming directory for contributions
/outgoingswap directory

Information for a particular application can be found in the README file,
located in the same directory as the application. The README files contain
information on new features, known bugs, compile information, and other
important notes.

All directories on the FTP server contain an INDEX file. These files outline
the hierarchical structure of the directory and (recursively) all files and
directories contained within it. The INDEX at the root level contains the
structure of the enire server listing all files and directories on it. The
INDEX file in each software directory contains additional information about
each file. The letter in parenthesis after the file name indicates how the
file should be downloaded: ascii (a), binary (b), or mac binary (m).

The "misc" directories found in some software tool directories contain
supplementary code or other information. Refer to the README file in that
directory for a description of what is contained within the "misc" directory.

The "contrib" directories contain contributed software. This directory usually
contains NCSA source that has been modified by people outside of NCSA as well
as binaries compiled on different platforms not available to the Software Tools
Group. If you have modified NCSA software or would like to share some code
please contact the developer of the source so arrangemnts can be made to upload
it to the "incoming" directory. If you are downloading software from the
"contrib" directory please note that this software is not supported by NCSA and
has not been checked for viruses (see statement on viruses above). NCSA may
not be held responsible for anything resulting from use of the contributed
software. *** RUN AT YOUR OWN RISK ***


All file names consist of the name of the tool, the version number, and one or
more extensions. The extensions identify what type of information is contained
in the file, and what format it is in. For example, here is a list of files in
the /Mac/DataScope directory:


The first three character extension indicates what type of data can be found in
that file (ASCII documentation, source, samples, etc.). The other extensions
indicate what format the files are in. The extensions ".tar" and ".sit"
indicate types of archives, and the ".Z" and ".hqx" indicate compression and
encoding schemes. (See below for instructions on extracting files that have
been archived and/or compressed.) Following are a list of extensions and their

.sn3 Sun 3 executables
.sn4 Sun 4 executables
.386 Sun 386i executables
.sgi Silicon Graphics Iris executables
.dgl Silicon Graphics Iris using DGL executables
.rs6 IBM RS6000 executables
.cv2 Convex 2 executables
.cv3 Convex 3 executables
.cr2 Cray 2 executables
.crY CrayYMP executables
.d31 DEC 3100 executables
.m88 Motorola 88k executables
.m68 Motorola 68k executables
.exe IBM PC executables
.mac Macintosh executables
.src source code
.smp sample files
.asc ASCII text documentation
.msw Microsoft Word documentation
.ps postscript documentation
.man formatted man page
.shar Bourne shell archive
.sit archive created by Macintosh application, StuffIt
.hqx encoded with Macintosh application, BinHex
.tar archive created with UNIX tar command
.Z compressed with UNIX compress command

The files in the PC directory are the only exception to this naming convention.
In order to conform with the DOS convention of eight character file names and
one, three character extension, the names for PC files are slightly different.
Whenever possible the scheme outlined above is used, but the names are usually
abbreviated and all but one of the dots "." have been omitted.



If a file ends with the extension ".sit" it must be unstuffed with either the
shareware program StuffIt or the Public Domain program UnStuffIt. Files ending
with the ".hqx" must be decoded with BinHex. These programs can be found on
the FTP server in the /Mac/Utilities directory. Note that the BinHex program
must be downloaded with MacBinary enabled, and the StuffIt program must be
decoded before it can be used. Files downloaded from the server may be both
Stuffed (".sit" extension) and BinHexed (".hqx" extension). These files must
be first decoded and then unstuffed.

To decode a file with the ".hqx" extension (a BinHexed file):

1. Download the file to your Macintosh.
2. Start the application BinHex by double-clicking on it.
3. From the "File" menu in BinHex, choose "UpLoad -> Application".
4. Choose the ".hqx" file to be decoded and select "Open".
5. The suggested file name will appear in a dialog box.
6. Select "Save" to decode the file.

To uncompress a file with the ".sit" extension (a Stuffed file):

1. Download the file to your Macintosh.
2. Start the application Stuffit by double-clicking on it.
3. From the "File" menu in Stuffit, choose "Open Archive...".
4. Choose the ".sit" file to be unstuffed and select "Open". A window with
all the files contained in the stuffed file will appear.
5. Choose "Select All" in the "Edit" menu to select all of the files.
6. Click on the "Extract" box at the bottom of the window.
7. Select "Save All" in the dialog box to save all the selected files in
the current directory.


Most IBM PC files are archived and compressed using the pkzip utility.
(If you do not have the pkzip utility on your PC, you may obtain it from the
FTP server by anonymous ftp. The file you need is called pkz110.exe and it
is located in /PC/Telnet/contributions. Set the ftp mode to binary and "get"
the file pkz110.exe. Then, on your PC, run PKZ110.EXE with no arguments and
several files will be self-extracted, including one called PKUNZIP.EXE. It
may then be convenient to copy PKUNZIP.EXE to the directory where you have
placed, or are going to place, your Telnet files.)
To extract these files, first download the file with the ".zip" extension to
your PC and then type the following at the DOS prompt:

> pkunzip -d

where "filename" is the name of the file you want to unarchive.


Most files on the FTP server will be both tarred and compressed. For more
information on the "tar" and "compress" commands you can type "man tar" and
"man compress" at your shell prompt to see the online manual page for these
commands, or ask your system administrator for help. You should first
uncompress and then unarchive files ending in ".tar.Z" with the following

Files with the ".Z" extension have been compressed with the UNIX "compress"
command. To uncompress these files type the following at the shell prompt:

% uncompress filename.Z

where "filename.Z" is the name of the file ending with the ".Z" extension that
you wish to uncompress.

Files with the ".tar" extension have been archived with the UNIX "tar" command.
To extract the files type the following at the shell prompt:

% tar xf filename.tar

Some files are archived using a shell archive utility and are indicated as such
with the ".shar" extension. To extract the files type the following at the
shell prompt:

% sh filename.shar

Members of the Software Tools Group within NCSA are currently working on
videotapes that demonstrate and also offer tutorials for NCSA programs. A
note will be posted here when these tapes are available for distribution.


ASCII text files are provided for all software and are indicated with the
".asc" extension. Helpful figures and diagrams obviously cannot be included
in this form of documentation. We suggest you use the other forms of
documentation if possible.


If you are a Macintosh user, please download documents with the ".msw"
extension. These files should also be stuffed and BinHexed (information on
extracting these files from the archive is contained earlier in this file).
The documents can be previewed and printed using the Microsoft Word
application. Word documents contain text, images, and formatting.


If you are a UNIX user and/or have access to a postscript printer, please
download files with the ".pos" extension. The documents can be previewed using
a poscript previewer or can be printed directly to a poscript printer using a
command like "lpr".


The Software Tools Group at NCSA is very interested in how the software tools
developed here are being used. Please send any comments or suggestions you
may have to the appropriate address.

NOTE: This is a new kind of shareware. You share your science and
successes with us, and we can get more resources to share more
NCSA software with you.

If you want to see more NCSA software, please send us a letter,
email or US Mail, telling us what you are doing with our software.
We need to know:

(1) What science you are working on - an abstract of your
work would be fine.

(2) How NCSA software has helped you, for example, by increasing
your productivity or allowing you to do things you could
not do before.

We encourage you to cite the use of any NCSA software you have used in
your publications. A bibliography of your work would be extremely
