SUPERFETCH: V1.0
System Requirements
- Unix or Lynyx operating system
- Perl 5 with sockets library installed
- Telnet access
- Ability to run cgi outside of your cgi-bin is recommended
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.
- If you need to review or learn the basics of CGI and Perl check out the superscripts tutorial archives.
- Download the tarfile for this program and save it to your desktop.
- 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.
- 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.
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 the .cgi files
superfetch.cgi lines 23-25
$remote = "www.cybercore.net";
- $output = "network.gif";
- $url = "/pix/network.gif";
- $remote is the DOMAIN NAME of the server you are RETRIEVING your file from
- $output is the NAME of the specific file you are SAVING on your unix machine
- $url is the PATH of the FILE from the domain on the FILE SERVER
- eg: in this example configuration I am fetching a file called network.gif located at http://www.cybercore.net/pix/network.gif
File Access Permissions
File access permissions must be set correctly for this program to run. The table below lists the permissions of each file which are to be set by the unix command ( chmod ) used to set the correct access permissions. You must set the access permissions for each of these files.
CHMOD 755
CHMOD 777
superfetch.cgi
DIRECTORY YOU RUN
SCRIPT IN
or a blank text file
named according to $output
(see below)
Running the program
Now simply run superfetch.cgi from shell
perl superfetch.cgi
- NOTE!!! The directory you are running this in MUST be set to chmod 777 or NO NEW FILES
- can be uploaded this way! If this is not possible then simply upload a BLANK text file and title it
- according to $output (i.e. in the example configuration I am retrieving a small 4K gif from my main server (cybercore.net)
