In order to run CGI scripts
on the School of Information server, you will need to use a program
called CGI Wrap. CGI Wrap is a program which allows users to execute
CGI content while maintaining security for the server. The following
instructions assume that you have a knowledge of CGI programming
and HTML.
The first thing you need to do to use CGI Wrap is create a directory
under your public_html directory. In order to do this, move into your
public_html directory and create a cgi-bin
directory. From your home directory, type:
cd public_html
mkdir cgi-bin
Now, you need to make your cgi-bin directory executable by
the world. Type:
Now, you can either create CGI scripts in this cgi-bin directory,
or copy scripts you've written elsewhere into your cgi-bin directory.
When you are creating HTML forms that reference your CGI scripts (or
you are using CGI scripts that aren't called from a form), you have
to use a special path that calls CGI Wrap and tells it where to find
your script. So if your username is coder, and you've
created a script named script.cgi, you would place the
following URL into the action attribute of an HTML form tag:
http://www.ischool.utexas.edu/cgi-bin/cgiwrap/coder/script.cgi
One of the benefits of using CGI Wrap is that it has a special debugging
mode that gives you lots of information on your script and prints
out as plaintext what it is sending to the server. In order to use
the debugging mode, you call cgiwrapd instead of cgiwrap
(notice the d on the end). Thus, your action attribute
would now look like:
http://www.ischool.utexas.edu/cgi-bin/cgiwrapd/coder/script.cgi
To summarize, the URL of a CGI script using CGI Wrap is:
http://SERVER/cgi-bin/cgiwrap/USER/SCRIPT
