The news server does not feed this article to any newsfeed server whose host name appears in the path header. INN uses this mechanism to prevent newsfeed servers from sending back copies of news articles they have received.
b.This step is optional. In the Newsgroups to Propagate and Newsgroups NOT to Propagate fields, enter the newsgroups you want sent or not to be sent to your news server. The newsgroups that match the specifications in these fields constitute the subscription list for your site. Use the default subscription list to allow your news server to receive all articles from all newsgroups (except control, local.*, and junk).
You can also use these fields to filter out articles from certain newsgroups. For example, to receive all articles from all comp newsgroups, but only the articles from the comp.sources.unix subgroup within the sources newsgroups, specify the following values:
Send These Newsgroups: comp.*,comp.sources.unix
Do NOT Send These Newsgroups: comp.sources.*
In this example, the trailing asterisk (.*) is a required part of the pattern. Also, the result of the last match is the most important.
c.In the Distributions field, modify a subscription that your server will be able to send. These modifications extend the modifications of Send These Newsgroups entries.
You can modify a subscription by specifying distributions that the site can or cannot receive. The default distribution is to send all articles to all sites that subscribe to any of the newsgroups where the article has been posted. However, if an article has a distribution header with specific distributions, the specifications are checked according to the following rules:
•If the distribution header matches any of the values in the subscription field, then the article is sent.
•If a distribution entry starts with an exclamation point, and it matches the distribution header, then the article is not sent.
•If the distribution header does not contain any distributions that match any distribution specifications in the site's entry form, and no negations were used, then the article is not sent. (An exclamation point negates a distribution entry.)
•If the distribution header does not contain any distributions that match any distribution specifications in the site's entry form, then the article is sent.
If an article has more than one entry specified in a distribution, then each one is evaluated according to these rules:
•If any of the specified distributions indicate that the article can be sent, then it is sent.
•If none of the specified distributions indicate that the article can be sent, then it is not sent.
The rules are evaluated as a logical OR.
To avoid errors in the evaluation of distribution rules, be consistent in the use of exclamation points in distribution specifications. Do not have a single feed that specifies distributions starting with an exclamation point along with some distributions with no exclamation points.
Note that distributions are text words, not patterns. For example, avoid entries such as
*or all.
See the newsfeeds(5)reference page for details on distribution lists.
d.This step is optional. In the Flags and Parameters field, specify flags in any order, separated by commas. Do not insert a space between the flag letter and the flag value.
Typically, a newsfeed has the following flags set:
