Web based port scanner

Build a web passed port scanner using PHP -- JS. JQuery, Ajax are available. We run a Drupal site, so it must function within Drupal. It can be a Drupal module, or we can call it from our Drupal module. Nmap is installed on the server and available for use, although we will consider other options. Module will need to function as follows: 1. Client cannot specify IP, it will only scan their originating IP 2. Simple scan will check specific ports and report for each port: Open, Closed or Stealth (not found) 3. Advanced scan will check all ports and report for port: Open, Closed or Stealth (not found) 4. We need to log client info, IP address, date, time and results, so this information must be available. We will do the database insert ourselves. That’s it – should be pretty easy if you have experience with port scanners. We will show you an example of how it needs to function. We will do the front-end work, so it doesn’t need to be pretty - we just need to be able to access the data.
