Q.  How do I scan all the computers on my LAN?

A.  Like this:

nmap 192.168.40.0/24
Change the IP-address to suit your LAN. This will look at:
192.168.40.0 192.168.40.1 192.168.40.2 ... 192.168.40.254 192.168.40.255
256 computers. A cool trick of nmap... It can tell you the manufacturer of a device on your LAN based on its MAC address. So you want find the IP-address of your Cisco voip box? Scan the LAN with nmap.
