|
|
The active file is located in /usr/lib/news and lists all groups
|
|
known at your site, and the articles currently online. You will rarely
|
|
have to touch it, but we explain it nevertheless for sake of
|
|
completeness. Entries take the following form:
|
|
<PRE>
|
|
newsgroup high low perm
|
|
|
|
</PRE>
|
|
|
|
newsgroup is, of course, the group's name. low and
|
|
high are the lowest and highest numbers of articles currently
|
|
available. If none are available at the moment, low is equal to
|
|
high+1.
|
|
<P>
|
|
At least, that's what the low field is meant to do. However, for
|
|
efficiency reasons, C-News doesn't update this field. This wouldn't be
|
|
such a big loss if there weren't some newsreaders that depend on it.
|
|
For instance, trn checks this field to see if it can purge any
|
|
articles from its thread database. To update the low field, you
|
|
therefore have to run the updatemin command regularly (or, in
|
|
earlier version of C-News, the upact script).
|
|
<P>
|
|
perm is a parameter detailing the access users are
|
|
granted to the group. It takes one of the following values:
|
|
<DL><DT>y<DD> Users are allowed to post to this group.
|
|
<DT>n<DD> Users are not allowed to post to this group. However, the group may still be read.
|
|
<DT>x <DD>This group has been disabled locally. This happens sometimes when news admininistrators (or their superiors) take offense
|
|
to articles posted to certain groups.
|
|
<P>
|
|
Articles received for this group are not stored locally,
|
|
although they are forwarded to the sites that request them.
|
|
<DT>m<DD> This denotes a moderated group. When a user tries to post to this group, an intelligent newsreader will notify her of this,
|
|
and send the article to the moderator instead. The moderator's
|
|
address is taken from the moderators file in /usr/lib/news.
|
|
<DT>=real-group<DD> This marks newsgroup as being a local alias for another
|
|
group, namely real-group. All articles posted to newsgroup
|
|
will be redirected to it.
|
|
|
|
</DL>
|
|
In C-News, you will generally not have to access this file directly.
|
|
Groups may be added or deleted locally using addgroup and
|
|
delgroup (see below in section-<A HREF="#cnewsmaint"><IMG ALIGN=BOTTOM ALT="gif" SRC="cross_ref_motif.gif"></A>).
|
|
When groups are added or deleted for the whole of Usenet, this
|
|
is usually done by sending a newgroup or rmgroup
|
|
control message, respectively. <em>Never send such a message yourself!</em>
|
|
For instructions on how to create a newsgroup, read the monthly
|
|
postings in news.announce.newusers.
|
|
<P>
|
|
A file closely related to active is active.times. Whenever
|
|
a group is created, C-News logs a message to this file, containing
|
|
the name of the group created, the date of creation, whether it
|
|
was done by a newgroup control message or locally, and who did it.
|
|
This is for the convenience of newsreaders who may notify the user
|
|
of any recently created groups. It is also used by the
|
|
NEWGROUPS command of NNTP.
