Telnet Overview

Telnet offers users the capability of running programs remotely and facilitates remote administration. Telnet is available for practically all operating systems and eases integration in heterogeneous networking environments.

MORE About Telnet


Telnet is best understood in the context of a user with a simple terminal using the local Telnet program (known as the client program) to run a logon session on a remote computer where the user's communications needs are handled by a Telnet server program.

It should be emphasized that the Telnet server can pass on the data it has received from the client to many other types of processes including a remote logon server. This is described in RFC854 and was first published in 1983.

The Network Virtual Terminal

Communication is established using TCP/IP and is based on a Network Virtual Terminal (NVT). On the client, the Telnet program is responsible for translating incoming NVT codes to codes understood by the client's display device as well as for translating client-generated keyboard codes into outgoing NVT codes.

The NVT uses 7-bit codes for characters. The display device, referred to as a printer in the RFC, is only required to display the standard printing ASCII characters represented by 7-bit codes and to recognize and process certain control codes. The 7-bit characters are transmitted as 8-bit bytes with the most significant bit set to zero. An end-of-line is transmitted as a carriage return (CR) followed by a line feed (LF). If you want to transmit an actual carriage return, this is transmitted as a carriage return followed by a NUL (all bits zero) character.

NVT ASCII is used by many other Internet protocols like SMTP and FTP.

The following control codes are required to be understood by the NVT.

 
Name Code Decimal Value Function
NULL NUL 0 No operation
Line Feed LF 10 Moves the printer to the next print line, keeping the same horizontal position.
Carriage Return CR 13 Moves the printer to the left margin of the current line.


The following further control codes are optional but should have the indicated defined effect on the display.

 
Name Code Decimal Value Function
BELL BEL 7 Produces an audible or visible signal (which does NOT move the print head.
Back Space BS 8 Moves the print head one character position towards the left margin. (On a printing device, this mechanism was commonly used to form composite characters by printing two basic characters on top of each other.)
Horizontal Tab HT 9 Moves the printer to the next horizontal tab stop. It remains unspecified how either party determines or establishes where such tab stops are located.
Vertical Tab VT 11 Moves the printer to the next vertical tab stop. It remains unspecified how either party determines or establishes where such tab stops are located.
Form Feed FF 12 Moves the printer to the top of the next page, keeping the same horizontal position. (On visual displays, this commonly clears the screen and moves the cursor to the top left corner.)
The NVT keyboard is specified as being capable of generating all 128 ASCII codes by using keys, key combinations, or key sequences.
