Because it is actually "netstat -anp" that will (also) list the services. The reason for using nmap is that it is a popular tool for ... mapping other's people machines. As such, you may want to know about its existence and defend yourself against it. There are certainly other methods, but that's the one I happen to have mentioned. But, yes I will add the netstat thing, also because it is the way for retrieving services and deleting them (as from point 8). Sergio
