Testing a TCP/IP Protocol Stack

If you are running under TCP/IP, there are several applications that you can use to test the compatibility of the client computer and server computer TCP/IP protocol stack.

The ping utility provided with many TCP/IP packages is useful for testing the IP network layer.

• Using Ping to Test the IP Layer
  Each IP layer has an associated address—a four-integer period-separated number (such as 191.72.109.12). Ping takes as an argument an IP address and attempts to send a single packet to the named IP protocol stack.
• Using Telnet to Test the TCP/IP Stack
  To further test the TCP/IP stack, start a server application on one computer, and a client program on the other computer, and test whether they can communicate properly.
