Blocking news groups from being fed to downstream servers is controlled by the configuration file /var/news/config/newsfeeds (see newsfeeds(4) for an extensive description).
The format for newsgroup blocking is:
server-name:sendgroup,!blockgroup1,!blockgroup2...::
For example, the entries
ME:*,!control,!junk,!local.*:: news.otherplace.com:*,!alt.binaries.*,!local.*::
Send all news groups except control
, junk
, and any group beginning local.
to all servers by default.
Send all groups except groups begining with alt.binaries.
or local.
to the server named news.otherplace.com
.
After you make changes to /var/news/config/newsfeeds, you must stop then start the news server using snsnews.
