Hi, I would like the IETF-NNTP group to meet at the July/August IETF in Atlanta to discuss the v2 draft, authentication issues, developments on the SMTP/Mail side of the house, and news reader protocols. I'm about 2/3 away through a rewrite, and I'm awaiting more information from other sources in terms of authentication and whether or not to expand newsreader functionality in the Transport Protocol. One final thought (for the moment) - at some point it was suggested that the OPTION command be eliminated in favor of additional commands, so that turnarounds could be further reduced. Comments? Here is information about the upcoming meeting.

Is it really the case that the only new stuff in the NNTP protocol is Brian's original ideas? If so, that is a big mistake. -Syntax of "search" command is not good, or did we decide to leave it out? -I don't think we ever really reached consensus on the authentication, or did we? -I really REALLY want a "mode" command -- I have software in beta-test that could use this right now (see the archives, around April 20) -Elliot asked about flushing the "batch" command. Are we? Or what about Brian's suggestions of May 1? -What about "438 offer me this one later"? We must resolve these issues before we can say we're done. /r$

-I don't think we ever really reached consensus on the authentication, or did we? I, too, do not have the impression that consensus was reached. I looked back over the notes I did save (not all of them), and derived the following: 1. Host (or connection?) level authentication seems the most appropriate. A point that was not resolved was whether or not this should be mutual or just the "client" authenticating itself to the "server". 2. Confidentiality was briefly discussed, but it seems more appropriate at the newsgroup level. Since newsgroups are not defined at the NNTP level, this is probably a service for a higher layer. 3. The closest thing to consensus with respect to a mechanism was a number of suggestions to use id/password pairs. My opinion is this may be okay for now, while we wait for the CAT working group to do its thing. Kerberos was also suggested. This is my recollection and interpretation of what I saved. It could be wrong. Jim

Rich, reader additions to the protocol are on hold until we see just how far we can get on an NNRP. I don't have any particular objections to the MODE command, other than that the default MODE needs to handle the old functionality. Among other things it would not require an additional port assignment. However, I am far more interested in what the reader MODE/protocol would look like, than how to get to it, at this point. Stan likes the idea of the OPTION command. As long as you can lump all the options together, I won't object, either. Brian's suggestion was to flush the OPTION command. Again, I'm in mid-rewrite so hang in there for just a bit longer... Eliot Lear [lear@turbo.bio.net]

From ietf-nntp-request@turbo.bio.net Mon Jun 24 12:34:01 1991 From: Eliot <lear@turbo.bio.net> Rich, reader additions to the protocol are on hold until we see just how far we can get on an NNRP. I don't have any particular objections to the MODE command, other than that the default MODE needs to handle the old functionality. This assumes that whatever is listening on the other 'end' of the connections handles all the current requests. In this case, that is not true. In my opinion, the original spec errored in being to tied to a particular implimentation. Among other things it would not require an additional port assignment. Why should NNRP not be granted an additional port assignment? Heck, POP has three of 'em now! Stan likes the idea of the OPTION command. As long as you can lump all the options together, I won't object, either. Brian's suggestion was to flush the OPTION command. NNTP should be for transfering news. NNRP should be for reading news. As far as IMAGE, while it is true that changing into and back out of the '\r\n' line termination on Un*x, there is a simple solution for this as well. Don't transform the '\r\n' on input if you're just going to store the article. "But this breaks our storage model, because the newsreaders have direct access to the files!", someone will object. Time to catch up with technology, man. The current storage model is broken. Just ask anyone who attempts to keep 6 months of news on-line. Jim Eliot Lear [lear@turbo.bio.net]
