WebMap runs the nmap security audit tool from a Web user interface. It presents a Web forms-based user interface to let the user configure options to execute nmap, executes nmap, and presents the output results in the same Web page.
WhoisUP monitors hosts via ICMP and shows the status in a webpage. When a host is down, it can send mail, write a syslog message, open a popup message, or play a sound. It uses Nmap to check hosts continuously.
