Minutes of the TELNET Working Group (TELNET)

The Telnet Working Group met in two sessions on Tuesday, March 30, 1993.
In the morning the Group first discussed the Environment Specification,
RFC1408.  This document contains an error in two sub-option values.  It
appears that more implementations do what the BSD/Cray implementation
does than actually follow RFC1408.  The Group agreed to update RFC1408
with the correct values and some text discussing interoperability.
Steve Alexander will update the document and send it out for review.

The Working Group then discussed the latest draft of the Kerberos V
authentication mechanism.  This has been updated with support for
delegation of credentials.  Ted Ts'o from MIT indicated that this had
been implemented and works.  Ted also mentioned that the general
authentication option needs a way to indicate that credentials will be
delegated.  The Group agreed to this.  With support in the general
mechanism, some changes will be needed to the Kerberos V mechanism
document as well.

The next topic was Dave Borman's new merged authentication/encryption
document.  The document was only briefly discussed since the most recent
version came out the Friday before the meeting.  It was agreed that
Steve Bellovin's suggestion that the document explain why encryption
cannot be turned on once it has been turned off should be adopted.  This
recommendation and the credential delegation suggestion will be
forwarded to Dave.

Jeff Schiller recommended that the Working Group Chair be more zealous
in getting new drafts out as Internet-Drafts.  There was general
agreement on this point.

The Group spent the remainder of the morning discussing the HP proposal
for Telnet multiplexing (Telnet MPX). It was generally agreed that HP's
performance numbers were very impressive, but the consensus was that
Telnet was not the best place to implement this.  The Group recommended
that a general solution, possibly at the transport or network layers
would be a better approach.  It was also recommended that HP move the
multiplexing mechanism to a TCP port other than 23 for experimentation,
and that the revised document be issued as an Experimental RFC. There
was also a brief discussion on enhancements to the MPX packet format.

The evening session was devoted to a discussion of Telnet 3270 emulation
(TN 3270).  Robert Moskowitz from Chrysler gave a synopsis of defects in
the current TN3270 implementations.  There was general agreement on
these problems and the proposed solutions.  In discussion with Russ
Hobby, it was decided that TN3270 was somewhat tangential to the issues
that the Telnet Working Group is pursuing.  TN3270 implementors and
users will form their own working group in the Applications Area.
TN3270 will remain a telnet-based service so that features like

Authentication and the Environment Option can be utilized if desired.
