- /var/news/etc/iind - news server process, controls the flow of news, access, etc. Listens on port 119.
- in.nnrpd - news reader, 1 per client
- nntplink - newsfeed sender process
- hosts.nntp - defines new servers (newsfeeds)
- nnrp.access - authorisation file, determines who has news reader access.
- newsfeeds - outgoing news. Lists what is sent out, name, etc.
N.B. Most newsfeeds sent via nntplink but can also be scheduled using nntpsend
- /var/news/out.going - what is currently getting sent out. normally ther should only be a link file which is a housekeeping file with stats in. if a backlog file with pid tag is present, data is still waiting to be sent.
- /var/news/active - list of groups acceptable on the server. Use ctlinnd newsgroup groupname to update. news groups are automatically added to the active file
