INN (InterNetNews) is a complete system for serving Usenet news and/or private newsfeeds. INN includes innd, an NNTP (NetNews Transport Protocol) server, and nnrpd, a newsreader that is spawned for each client. Both innd and nnrpd vary slightly from the NNTP protocol, but not in ways that are easily noticed.

Install the inn package if you need a complete system for serving and reading Usenet news. You may also need to install inn-devel, if you are going to use a separate program which interfaces to INN, like newsgate or tin.
