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-nkview.cgi

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

NAME

       hobbit-nkview.cgi - Xymon Critical Systems view CGI

SYNOPSIS

       hobbit-nkview.cgi

DESCRIPTION

       hobbit-nkview.cgi is invoked as a CGI script via the hobbit-nkview.sh CGI wrapper.

       hobbit-nkview.cgi matches the current critical statuses against the hobbit-nkview.cfg(5) file, and generates the "Critical Systems" view.

RELATION TO BBNK PAGE

       This view is a replacement for the statically generated "bbnk" page provided in versions of Xymon prior to version 4.2. Although the "bbnk"
       pages are supported throughout Xymon 4.x, it is recommended that You switch to the newer Critical Systems view provided by this CGI.

OPTIONS

       --nkacklevel=NUMBER
	      Sets the acknowledgment level for acknowledgments sent via the hobbit-ackinfo.cgi(1) page. Note that this may be overridden  by  the
	      configuration of the hobbit-ackinfo.cgi utility.

       --env=FILENAME
	      Loads the environment defined in FILENAME before executing the CGI script.

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

       --debug
	      Enables debugging output.

ENVIRONMENT VARIABLES

       BBHOME Used to locate the template files for the generated web pages.

       QUERY_STRING
	      Contains the parameters for the CGI script.
