- Opening Comments:
- Telnet Option draft RFCs - What are in the queue??
-
- o Borman's Telnet Linemode: This is in the queue now for
- becoming an RFC. It has been handed off to Phill Gross.
-
- o Berstein's Q-Method: For later discussion in this meeting,
- see item 6
-
- Borman presented proposed agenda to group and asked what else
- should be included:
- Bill Westfield lobbied for a document on Telnet with X.3
- negotiations -- he was overruled. It was decided that this along
- with item 10, was out of the scope of this group.
- RFC 854 and Postel - Is there a justification for a "revised"
- Telnet spec?? There seemed to be general agreement that a better
- approach would be to answer all the other questions first, and
- that would decide this question for us.
- The next item up for discussion was possible future options for
- Telnet that are needed.
-
-
-
- 2
- Pursue??_ What_to_include:_
- Yes User Name (who you're going in as, i.e., name,
-
- acct, etc.)
- Yes Authentication (get rid of RLogin) (Authentication
- and encryption are somewhat related.)
- Yes Environment
- Possibly System Type
- Yes Encryption (Encryption and authentication are
- somewhat related.)
- Maybe Compression (data) (A subcase of encryption?? A
- maybe, depending upon encryption.)
- Yes don't Telnet Option (Bill Westfield working on this one.)
-
-
- Big Topics:
-
- Go through which Telnet options are not needed.
- Send a message out to a mailing list asking who currently
- uses what telnet options. The following list is what we
- came up with at the meeting. Those marked with YES were
- changed from "no", those marked with a ? no one was sure
- on. (This is re-constructed from memory, so please let me
- know if I made a mistake... -Dave B.)

- Clarifying Timing Mark RFC
- Does anyone use STATUS??

- What's wrong with the current Telnet spec:
-
- o old stuff
- o what to update
-
-
- Other Issues:
- Borman's concept of the new Telnet Working Group:
-
- This group is not to disband, but upon completion of their
- activities, go dormant from time to time, and start up and
- become available as a group to review Telnet draft RFCs,
- etc....as needed.
-
- Discussion/Issues of 7 bit, 8 bit binary:
-
- 1. Delay problem between client and server, interrupt character,
- interrupt systems, interrupt marker - Linemode really helps
- you here in this realm.
-
- 2. Interrupt - telnet process can control things, output prompt
- between the two.
-
- 3. Host Requirement RFC document - discussion regarding "clean
- wording" of Telnet in the Host Requirement RFC. In particular,
- a statement on 7, 8 bit data passing; 8 bit should NOT be used
- for parity bit.
-
- 4. Should anything be said in the Host Requirement RFC re: 7, 8
- bit?? What about the statement of "SHOULD or MUST" negotiate
- binary??
-
- 5. Should the Telnet standard be changed/updated to reflect the
- context of Host Requirements RFC??
-
- 6. Items d and e were not resolved at this meeting. There is a
- need to soften the wording on the Telnet statement that's
- going into the Host Requirements RFC. Borman to talk to
- Braden.
-
- 7. Bernstein's Q-Method RFC. Postel asked the Telnet WG to review
- and comment. Group comment is that it should not be issued as
- an RFC. Part of it should be rewritten, and incorporated with
- whatever we release for a replacement/update to the Telnet
- RFC. It was felt that the real world was not having problems
- with option negotiation loops, so it isn't a problem that
- requires an immediate solution.
-
- Conclusion of meeting:
-
- o Telnet WG will meet in Hawaii.
-
-
-
- 5
- o Interim discussions will continue on the
