Selling redistributing or modifying any or

System Requirements

Perl 5l

Preliminaries

Determine the path to PERL 5 on your web
server host. Note that some web hosting companies run both PERL 4 and PERL 5.
Make ABSOLUTELY sure you are not setting this up under PERL 4. Ask your
administrator if you are not sure. l

If you
need to review or learn the basics of CGI and Perl visit the tutoriall

Download the
tarfile for this program and save it to your desktop.l

Unpack the tar archive on your desktop using a
program that unpacks UNIX TAR ARCHIVES. If you don't have such a program then download
WINZIP FREE from SHAREWARE.COM. l

After you have unpacked the TAR archive you
will have a collection of folders and files on your desktop. Now you have to do some
basic editing of each of these files (or at least some of them). Use a text editor
such as wordpad, notepad, BBEdit, simpletext, or teachtext to edit the files. These
are NOT WORD PROCESSOR DOCUMENTS they are just simple TEXT files so don't save them as
word processor documents or save them with extentions such as .txt or they will NOT WORK.
Note that there may be a some files inside of folders which are "blank".
This is normal.l

Preparing the CGI scripts

Define Path To PERL 5

The first step is to open up each and every
file that has a .cgi extention and edit line number one of each script. Each of the
cgi scripts is written in perl 5. For your scripts to run they must know where perl 5 is
installed on your web server. The path to perl 5 is defined to a cgi script in the first
line of the file. In each of the cgi scripts the first line of code looks something like
this:

#!/usr/bin/perl

If the path to perl 5 on your web server is
different from /usr/bin/perl you must edit the first line of each cgi script to reflect
the correct path. If the path to perl 5 is the same no changes are necessary. If you do
not know the path to perl 5 ask the webmaster or system administrator at your server site.

Configure htmlock.cgi

edit path to webpage

Find the line inside htmlock.cgi where the
HTMLFILE is opened and put the FULL path to your protected page.

open (HTMLFILE,
"/full/path/to/html/path/to/protect/webpage.html");

Add Javascript (norightclick.java) to
HTML PAGE

Insert the javascript included in the file
norightclick.java right underneath the <body> tag at the beginning of the webpage.

Chmod the files

Chmod htmlock.cgi to 755 and chmod your
webpage to 666 or 777

Edit the new protected page (see
demopage.html)

Create a new HTML webpage using the
index.html file as an example. Just substitue the url to htmlock.cgi in the HTML.
Use this page instead of the original source HTML page. When the surfer goes
to this page all will look normal except they won't be able to steal anything!

VERY IMPORTANT!

Do NOT use relative links to images or urls
or your page will not work right. You have to use full URI's and URL's. If you
try otherwise you will get broken links. So DON'T FORGET THIS!
