Changing to NNRP Reader Mode

Changing to NNRP Reader Mode

Newsreaders use their own set of commands when talking to a news server. To activate these commands, the news server has to be operating in reader mode. Most news servers default to reader mode, unless the IP address of the connecting host is listed as a news-forwarding peer. In any case, NNTP provides a command to explicitly switch into reader mode:

mode reader
200 news.vbrew.com InterNetNews NNRP server INN 1.7.2 08-Dec-1997 ready/
    (posting ok).

.

NNTP reader mode has a lot of commands. Many of these are designed to make the life of a newsreader easier. We mentioned earlier that there are commands that instruct the server to send the head and the body of articles separately. There are also commands that list the available groups and articles, and others that allow posting, an alternate means of sending news articles to the server.
