How to Log Onto Other Computer Ports

A port on a computer is an artificial opening from which data is sent and transmitted across a network. Certain ports are open and closed on a computer depending on the PC's security settings and firewall. Logging into a specific port on a computer can be necessary where the computer is otherwise blocked off to network traffic, allowing you to slip information through the only "opening" in the computer.

Instructions

Step 1

Open the "Start" menu and click on the "Run" button.

Step 2

Type in "cmd" and press Enter. This will bring up a command prompt.

Step 3

Type in "telnet computeraddress portnumber" where "computeraddress" is the IP address or other identifying label of the computer, and "portnumber" is the port to be accessed. For example, "telnet 123.456.78.90 80" will log in to a computer with an IP of 123.456.78.90 at port 80.
