  Network News Transfer Protocol - Biocrawler   (Site not responding. Last check: 2007-11-06)
As local area networks and the Internet became more commonly used, it became desirable to allow newsreaders to be run on personal computers, and a means of employing the Internet to handle article transfers was desired.
Because networked Internet-compatible filesystems were not yet widely available, it was decided to develop a new protocol that resembled SMTP, but was tailored for reading newsgroups.
The protocol remains in widespread use, and as of 2005 efforts are underway to produce an updated standard.

 RFC 977 (rfc977) - Network News Transfer Protocol
NNTP is designed so that news articles are stored in a central database allowing a subscriber to select only those items he wishes to read.
NNTP is designed so that news articles need only RFC 977 February 1986 Network News Transfer Protocol be stored on one (presumably central) host, and subscribers on other hosts attached to the LAN may read news articles using stream connections to the news host.
RFC 977 February 1986 Network News Transfer Protocol There is no prohibition against additional commands being added; however, it is recommended that any such unspecified command begin with the letter "X" to avoid conflict with later revisions of this specification.

NNTP specifies a protocol for the distribution, inquiry, retrieval, and posting of news articles using a reliable stream (such as TCP port 119) server-client model.
NNTP is designed so that news articles need only be stored on one (presumably central) server host, and subscribers on other hosts attached to the network may read news articles using stream connections to the news host.

 Network News Transfer Protocol - Wikipedia, the free encyclopedia
The Network News Transfer Protocol or NNTP is an Internet application protocol used primarily for reading and posting Usenet articles, as well as transferring news among news servers.
Brian Kantor of the University of California, San Diego and Phil Lapsley of the University of California, Berkeley completed RFC 977, the specification for the Network News Transfer Protocol, in March 1986.

 RFC 977: Network News Transfer Protocol
NNTP is designed so that news articles need only be stored on one (presumably central) host, and subscribers on other hosts attached to the LAN may read news articles using stream connections to the news host.
In the traditional method of distributing news articles, news is propagated from host to host by flooding - that is, each host will send all its new news articles on to each host that it feeds.
Because some host news posting software may not be able to decide immediately that an article is inappropriate for posting or forwarding, it is acceptable to acknowledge the successful transfer of the article and to later silently discard it.

 The Network News Transfer Protocol   (Site not responding. Last check: 2007-11-06)
NNTP, the Network News Transfer Protocol, is the protocol used to send Usenet news messages between servers and from a news server to newsreader clients.
It is a fairly simple protocol, similar in many ways to POP3 or SMTP and is of interest in part because of its simplicity (it's a lot easier to write one's own NNTP implementation for fun than it is to write one's own IMAP implementation for fun).
New standards that add an extension mechanism and document many of the changes since 1986 are currently awaiting publication.

 Network News Transfer Protocol
This document specifies the Network News Transfer Protocol (NNTP), which is used for the distribution, inquiry, retrieval, and posting of Netnews articles using a reliable stream-based mechanism.
Because some news server software may not be able immediately to determine whether or not an article is suitable for posting or forwarding, an NNTP server MAY acknowledge the successful transfer of the article (with a 235 response) but later silently discard it.
The newsgroups list is maintained by some news transfer systems to contain the name of each newsgroup that is available on the server and a short description about the purpose of the group.

It is a ``protocol for the distribution, inquiry, retrieval, and posting of news articles using a reliable stream-based channel[Kan86].'' The NNTP server listens on TCP port 119.
NNTP is analogous to SMTP in that the client issues ASCII commands and the server responds with 3-digit reply codes[Kan86].
News is distributed by newsfeeds, central repositories of news articles.
