How to Ping a Computer Port

A computer port is a location in the firewall that acts as a “window,” enabling data to come into the computer when open and preventing it from doing so when closed. Pinging a port refers to the process of sending a small amount of data to the port to test whether it is responsive to your requests. This can be done from the DOS command shell in your Windows OS.

Step

Open "Start" and click "Run."

Step

Type in "cmd" and press "OK."

Step

Type in "ping ipaddress:portnumber," replacing "ipaddress" with the IP address of the computer to be pinged and "portnumber" with the number of the port you wish to ping.

Step

Press "Enter" to ping the desired address and port.
