Internet Express for Tru64 UNIX Version 6.8 Administration Guide (14233)

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:
Tf,Wnm:newsfeed_hostname
T is the flag for the type of feed and f is the value for a file feed.
W is the flag that controls what information is written. The value n causes INN to write
the article's message ID to the file represented by the newsfeed_hostname file. The
value m causes the INN Server to write the article's message ID. This file is found in the
