Telnet

Introduction

Telnet lets you use the Internet to login to a remote computer (assuming you have login permission on the remote computer). For example, Niagara students using the NU computer network (or using a computer off-campus) can use Telnet to make a connection with cis.niagara.edu (from the NU network, you may use the abbreviation cis).

NOTE: For Telnet to function, you must be connected to the Internet (or, more generally, to a network that includes both the computer you're working at and the desired remote computer).  If you're working at your personal computer at home and are not connected to your Internet service provider (ISP), Telnet will not be able to connect you to the desired remote computer.

Finding Telnet on your computer

The ideal is to have a shortcut icon on your desktop for Telnet. If you don't, you might want to make one.

If you don't have a Telnet shortcut, and you're using a Windows computer, an easy way to find Telnet is by a search. Click Start, Search. If you're using Windows XP, choose All Files and Folders. Enter Telnet.exe for the file name and click Search. It is likely that under Search Results there will be several listings.  Try one of them.  If it doesn't work, try another.

Establishing your connection

Once you have started the program, use the open command to establish your connection to the desired remote computer. This command take the form

open remoteComputerAddress where remoteComputerAddress is the network address of the remote computer.  For example, if a Niagara student wishes to connect to cis.niagara.edu, s/he can use open cis if working at a "local" computer on the Niagara network; open cis.niagara.edu from off-campus.

NOTE: If you're working from a Unix computer that's on a network, to reach another computer on the network you can give a command of the form

telnet remoteComputerAddress for example, telnet cis.niagara.edu

Once you have established your connection to the remote computer, login and go merrily about your business on the remote machine.

When you're done using the remote computer, you should logout/exit from the remote machine before you exit the Telnet program.
