22.1. The NNTP Protocol
We've mentioned two NNTP commands that are key to how news articles are pushed or pulled between servers. Now we'll look at these in the context of an actual NNTP session to show you how simple the protocol is. For the purposes of our illustration, we'll use a simple telnet client to connect to an INN-based news server at the Virtual Brewery called news.vbrew.com . The server is running a minimal configuration to keep the examples short. We'll look at how to complete the configuration of this server in Chapter 23 . In our testing we'll be very careful to generate articles in the junk newsgroup only, to avoid disturbing anyone else.
