Objective 4: Serving News
Knowledge about how to configure a news server is required for the LPI Level 2 Exams. However, news servers receive even less emphasis than mailing lists. The LPI specifically mentions the InterNet News service (INN), which is offered by the Internet Systems Consortium (ISC) at http://www.isc.org. INN is currently in its second version, INN 2. Following is the essential information you need to know about this topic.

It is also possible to connect an NNTP server to a newsfeed, which makes it possible for the server to receive messages from all of the Usenet newsgroups on the Internet. Thousands of newsgroups exist. They are organized hierarchically. Top-level discussion categories include:
- alt

- comp
This category includes such computing-related groups as comp.lang.c, comp.lang.java, and comp.software.testing. The comp.os.linux series of groups is especially relevant to readers of this book.
- humanities
