INN Daemons

INN is composed of four daemons that interact with news servers on the Internet:

•innd—The primary news server daemon that handles all incoming newsfeeds, receives all incoming news articles, files and queues all articles for distribution to other sites, waits for connections on the Network News Transfer Protocol (NNTP) port, and implements all NNTP commands. NNTP specifies the method for distribution, inquiry, retrieval, and posting of news articles. It establishes standard commands that allow news servers to share news items with other news servers, and for clients to use news readers to read and post news items to and from servers.

•ctlinnd—Provides a front end to innd. All management of innd occurs through ctlinnd. It also handles all standard commands for adding and deleting newsgroups or shutting down the news server.

•innxmit—Transmits news articles to other newsfeeds.

•nnrpd—Handles all sending and receiving of news for your users' news reader programs and implements all NNTP commands (except for ihave and newnews).

For more information on InterNetNews, see the INN Web pages at http://www.isc.org/products/ INN. You can also review the set of FAQs in /usr/news/doc.

Specifying INN Configuration Data

Specifying INN configuration data is optional. When you choose Modify INN Configuration Data from the InterNetNews Administration menu, the INN Configuration Data form shows the current configuration for your news server, as shown in Figure 69.
