Description: Network protocol probing tool
 Amap allows you to probe IP ports for running protocols, ignoring the port
 number. It does this by sending probe packets to the port and analyzing the
 responses. This will allow you to find services running on non-standard
 ports.
 .
 Additionally, amapcrap is a tool that helps getting information for ports 
 that don't show any output.
 .
 Having nmap installed is suggested, since amap cannot scan for open ports
 (but there is an option to import nmap's output).
