We want to find the IP address, MAC address, Windows (NetBIOS) name
(if any), type of operating system, type of device, open listening TCP
ports, web servers on our network.

Use each possble IP address in our network's range.

Use ping to see if an IP address has a machine at it.
If it does, then do these too:
Use arp to discover the MAC address.

[Use nbtstat to find the NetBIOS name, if any.
  nbtstat -A 192.168.1.n     
 Foster lab XP's student user can't run nbtstat  :( ]

Use nmap -O to discover the open ports, OS type.
 If port 80, or 443, or 8080 is open try to connect to it and indicate
 the result.  
  By default the browser connects to port 80.  To connect to another
  port, specify the port after the domain name or IP address and a
  colon:  http://192.168.1.n:8080

In lieu of nbtstat we can match Windows NetBIOS names to IP address as
follows:  in Windows Explorer:
My Network Places | Entire Network |Microsoft .. | open each workgroup
name (e.g. "But umad admin") to see the list of NetBIOS names.  Ping
each of those to find its IP address.

Organize all this information.

Which nodes are inside the lab room, which outside?

When printing use small font and 0 top and bottom and left and right
margins to avoid wasting paper.
