Overview - Leafnode's Major Programs

For regular use

• Leafnode is the NNTP server. It talks to the local newsreaders (Emacs/Gnus, Mozilla Thunderbird, tin, slrn and others), and keeps track of the groups that are read.

  Leafnode is usually run by a super server such as xinetd, tcpsvd or inetd.

• Fetchnews is the program that gets news from upstream servers and sends your posted articles there. It will download articles for those groups that Leafnode was asked about.
  Fetchnews supports filtering incoming article headers for regular expressions, size and age.

  Fetchnews is usually run as a cron job or from a post-connect script (/etc/ppp/ip-up).

• Texpire is responsible for deleting old articles and repairing the news spool. It usually runs as a cron job.

For occasional use

• Applyfilter applies the contents of your filterfile to articles that you have already retrieved.
• Checkgroups inserts the titles of newsgroups into the newsgroup database.
• Newsq shows which news are waiting to be transferred to your upstream server.
