Tools of the Trade: nmap

The intent of this article is to familiarize the reader with the network scanner nmap. As Lamont Grandquist (an nmap contributor/developer) points out, nmap does three things: It will ping a number of hosts to determine if they are up. It will portscan hosts to determine what services they are offering and it will attempt to determine the OS (operating system) of host(s).
