15.6 Managing Article Expiration
News articles can accumulate quickly, depending on the newsgroups to which you subscribe
and the amount of news traffic for that newsgroup. As a result, a significant amount of disk space
can be consumed in a short time. Most news articles fed to you do not contain an expiration
header, or time limit, after which the article is purged from your system.
The /usr/news/etc/history file contains a record of news articles stored in the news system,
as well as those that have been received but since expired. If your InterNetNews (INN) Server
finds an article being offered to you recorded in the /usr/news/etc/history file, the server
determines that the article has already been offered and expires the article to avoid offering it
again.
When purging an article, the expire program supplied by the INN server breaks the link to
that article. For more information, see the expire(8) and the expire.ctl(5) reference pages.
Choose Modify Article Expiration Definitions from the InterNetNews Administration menu to
display the Modify Article Expiration Definitions menu. You can use this menu to perform the
following tasks:
• Display existing article expiration definitions (see Section 15.6.1: Displaying Article Expiration
Definitions)
• Add a new article expiration definition (see Section 15.6.2: Adding an Article Expiration
Definition)
• Modify an existing article expiration definition (see Section 15.6.3: Modifying an Article
Expiration Definition)
• Delete an article expiration definition (see Section 15.6.4: Deleting an Article Expiration
Definition)
• Modify the retention period for expired articles (see Section 15.6.5: Modifying the Retention
Period for Expired Articles)
