Hi Ariean

It's been ages since I did any html forms but the high level steps to get a webserver to do this are (not including installing the webserver or password the page for security!):
  1. Create an html page which is a 'form' in your webserver somewhere under the 'webroot' and has a method (probably) 'get' to pass back your user's inputs to your full scanning script
    <form action="/netezzascan2html.cgi" method="get">
    OR (batch job approach) have a noddy cgi script to drop a flag file containing the input parameters from the form which is then scanned by a separate, privileged process and used as input to the real netezza scanning script
  2. For a direct invocation of your ksh script your webservice process owner would have to have permissions to run the script (note ksh is fine for a cgi - you don't need perl or php in case you were wondering)
  3. For direct invocation the output from your script must start with an http header e.g. text/html or text/plain + blank line (& then the actual text or html code).
    OR for a batch invocation, a redirect to a URL for a file that your scanning script dumps output to, should work. Some javascript to delay loading the URL a few seconds or add a refresh interval for the URL would allow for delay in production of output file.
You can web search for more info on the forms - I found some at rebol dot com and w3schools

I *think* those are the very high level steps for getting a script to work through a web server.
Your web server error log contains the stderr output from a cgi script run that you would normally pick up in your terminal session. The main log will show if the cgi script has ben invoked.
I can give some examples if the ones out on the web aren't helping.

hobbit-statusreport.cgi

HOBBIT-STATUSREPORT.CGI(1)				      General Commands Manual					HOBBIT-STATUSREPORT.CGI(1)

NAME

       hobbit-statusreport.cgi - CGI program to report a status for a group of servers

SYNOPSIS

       hobbit-statusreport.cgi --column=COLUMNNAME [options]

DESCRIPTION

       hobbit-statusreport.cgi	is  a CGI tool to generate a simple HTML report showing the current status of a single column for a group of Xymon
       hosts.

       E.g. You can use this report to get an overview of all of the SSL certificates that are about to expire.

       The generated webpage is a simple HTML table, suitable for copying into other documents or e-mail.

       hobbit-statusreport.cgi runs as a CGI program, invoked by your webserver.  It is normally run via a wrapper shell-script in the CGI  direc-
       tory for Xymon.

EXAMPLES

       The  Xymon installation includes two web report scripts using this CGI tool: The hobbit-certreport.sh script generates a list of SSL server
       certificates that are yellow or red (i.e. they will expire soon); and the hobbit-nongreen.sh script generates a report of all statuses that
       are  currently  non-green.  These  can be accessed from a web browser through a URL referencing the script in the Xymon CGI directory (e.g.
       "/xymon-cgi/xymon-nongreen.sh").

OPTIONS

       --column=COLUMNNAME
	      Report the status of the COLUMNNAME column.

       --all  Report the status for all hosts known to Xymon. By default, this tool reports only on the hosts found on the current page from where
	      the CGI was invoked (by looking at the "pagepath" cookie).

       --filter=CRITERIA
	      Only  report  on	statuses that match the CRITERIA setting. See the bb(1) man-page - in the "hobbitdboard" command description - for
	      details about specifying filters.

       --heading=HTML
	      Defines the webpage heading - i.e. the "title" tag in the generated HTML code.

       --show-column
	      Include the column name in the display.

       --show-colors
	      Show the status color on the generated webpage. The default is to not show the status color.

       --no-colors
	      Do not include text showing the current color of each status in the report. This is the default.

       --show-summary
	      Show only a summary of the important lines in the status message.  By default, the entire status message appears	in  the  generated
	      HTML code. This option causes the first non-blank line of the status message to be shown, and also any lines beginning with "&COLOR"
	      which is used by many status messages to point out lines of interest (non-green lines only, though).

       --show-message
	      Show the entire message on the webpage. This is the default.

       --link Include HTML links to the host "info" page, and the status page.

       --embedded
	      Only generate the HTML table, not a full webpage. This can be used to embed the status report into an external webpage.

       --env=FILENAME
	      Load the environment from FILENAME before executing the CGI.

       --area=NAME
	      Load environment variables for a specific area. NB: if used, this option must appear before any --env=FILENAME option.
