Wow! I am lost already.
What I am after most specifically is to have a web page with an entry blank for a specified IP address entry. When the user submits the request, the page instructs the system to run a command with the IP address inserted into the command on the system. This command can be assigned the proper UID credentials and is also something I would normally run from the command line as a regular user. I will be calling nmap from the web page.
Your lofty assistance is appreciated.
