Abstract

   This document specifies the telnet Uniform Resource Identifier (URI)
   scheme that was originally specified in RFC 1738.  The purpose of
   this document is to allow RFC 1738 to be made obsolete while keeping
   the information about the scheme on standards track.

1.  Introduction

   URIs were previously defined in [RFC2396], which was updated by
   [RFC3986].  Those documents also specify how to define schemes for
   URIs.

   The first definition for many URI schemes appeared in [RFC1738].
   Because that document has been made obsolete, this document copies
   the telnet URI scheme from it to allow that material to remain on
   standards track.

2.  Scheme Definition

   The Telnet URL scheme is used to designate interactive services that
   may be accessed by the Telnet protocol [STD8].

   A telnet URL takes the form:

   telnet://<user>:<password>@<host>:<port>/

RFC 4248                 The telnet URI Scheme              October 2005


   The final "/" character may be omitted.  If :<port> is omitted, the
   port defaults to 23.  The :<password> can be omitted, as well as the
   whole <user>:<password> part.  Few implementations handle the user
   name and password very well, if at all.

   This URL does not designate a data object, but rather an interactive
   service.  Remote interactive services vary widely in the means by
   which they allow remote logins; in practice, the <user> and
   <password> supplied are advisory only: clients accessing a telnet URL
   merely advise the user of the suggested username and password.

   Many RFCs have added various services to the Telnet protocol for
   better authentication, encryption of traffic, or both.  Those RFCs
   have not specified new URI schemes for Telnet to invoke those
   services (along the lines of "https" being a different URI scheme
   from "http").  Some modern telnet clients attempt to invoke those
