You can then close the connection to the remote computer and exit the Telnet program. This should return you to the Telnet prompt on your system. If the remote computer stops responding to your commands, you can usually disconnect from the remote system by simultaneously depressing the control key and the ]. Normally these will be noted on the screen before you log in. In some cases you will be able to start using the remote computer's resources immediately in others you will need to enter a login name and password. This is similar to using anonymous FTP.Īfter entering the address, wait patiently for the connection to be established. If you do not specify a port, the computer will assume you are an authorized local user and request a valid username and password.

This port information appears as a number following the series of words or numbers in the address. Every Telnet site has two addresses - a word address or host name consisting of words separated by periods (good for people to remember) and a numerical address or network address composed of a series of numbers separated by periods (suited for use by a computer.) Some Telnet computers only allow the general public to access them through a specific port. To connect to a Telnet site, all you have to do is start your client program and type the address for the site. Once you log into a remote site, the program switches to command mode allowing you to send commands to the server.

Most work best using VT100 teminal emulation. Telnet sites are generally easy to use and have online help systems available. DOS, Macintosh and UNIX machines can all use the same program at the same time. Although many Internet services can be accessed with a Telnet provides general access to the programs on the remote computer without requiring any modifications for different local computer operating systems. Although time-sharing computers are designed to allow access to its resources by simultaneous, multiple users, there is a limit to the number of users that can be logged on at the same time.Ī Telnet client program is needed to connect to a Telnet server. The login procedure allows the computer to keep track of how many authorized users are using its resources at any given time. Once you are logged onto the remote server, the computer executes any commands that you type on your keyboard. Thus, the computer requires users to login with a user name and password. Only authorized users can access a time-sharing computer. In order to access a time-sharing computer, you must invoke terminal emulation software which causes your local computer to act like a terminal. When working at one of these terminals, the computer responds to your keyboard input instantly - you can't tell the difference between the time-sharing computers response and the response you observe on your single user PC. This computer's operating system is constantly switching very quickly between users to ensure that work at each terminal proceeds as if it were the only terminal in operation. The time-sharing computer allocates a particular portion of its resources each terminal to use to run programs. Each user accesses this computer from a terminal consisting of a keyboard, monitor and mouse. A time-sharing computer system allows one large computer to support multiple users simultaneously.
When using Telnet to access a remote server, your computer becomes a "dumb" terminal and acts analogously to a terminal on any time-sharing computer system. FTP allows you to copy information from a remote computer while Telnet allows you to run programs on the remote computer. Telnet is a text-based application that allows you to log into a remote computer server via your local computer and utilize the resources available on that computer server. Telnet is one of the original Internet application predating even e-mail.
