I would like to develop some type of "status" monitor that will tell me if certain devices on my internal network are alive/on or not. On my network I don't have a DNS server and all devices are on DHCP.
I figure I'll need to have (probably nmap) return to me the IP address of the device and the MAC address. If I have the MAC address I can display to the user the common name.
Any good place to start?
