[OpenISO] TELNET

[Std Lib0]

I picked telnet from the protocols on this list:
http://openiso.org/pipermail/discuss/2007-September/000005.html
I'm trying to use the markdown language:
http://daringfireball.net/projects/markdown/
http://daringfireball.net/projects/markdown/syntax
and adopting a width of 80 characters for the page:
http://ask.slashdot.org/article.pl?sid=07/07/07/1931246
Let me try analyzing the TELNET protocol under the initial classification:
http://openiso.org/pipermail/discuss/2007-September/000003.html

There are several telnet-related standards. I'm picking the RFC 854.
Of course this is only an initial tentative draft. Probably everything will
be modified.
I hope others can contribute expanding the comments and adding others.


OI STD-E???:2007 TELNET
====================

INTRODUCTION:
------------------------
This is the OpenISO evaluation of the RFC 854.

> The purpose of the TELNET Protocol is to provide a fairly general,
> bi-directional, eight-bit byte oriented communications facility. Its
> primary goal is to allow a standard method of interfacing terminal
> devices and terminal-oriented processes to each other. It is
> envisioned that the protocol may also be used for terminal-terminal
> communication ("linking") and process-process communication
> (distributed computation).

PROBLEMS:
-------------------

### Comment 1: ###
No use of UNICODE or other international character set approved by
OpenISO.

### Comment 2: ###
There is no message integrity verification, so commands can be inserted
and removed

### Comment 3: ###
There is no message secrecy, so commands and parameters can be seen

### Comment 4: ###
The authentication password is transmitted in plaintext

### Comment 5: ###
There is an alternative standard called SSH without the problems in
comments 1-4.

BENEFITS:
----------------

### Comment 5: ###
Simple set of commands, easily implementable.

### Comment 6: ###
The plaintext protocol is so raw that it can be used to manually debug and
interact with other simple plaintext protocols such as HTTP, by sending
plaintext queries and visualizing the responses.


CONCLUSION:
----------------------
- Discouraged: See Comments 1,2,3,4,5.
- No Patents: See Comment #.
