NAME

       active - List of newsgroups carried by the server

DESCRIPTION

       The file pathdb/active lists the newsgroups carried by INN.  This file is generally
       maintained using ctlinnd(8) to create and remove groups, or by letting controlchan(8) do
       so on the basis of received control messages; this file is then updated and a backup
       stored in pathdb/active.old.  Note that the newsgroups(5) file normally contains the
       descriptions of the newsgroups carried by the news server.

       The active file should not be edited directly without throttling innd, and must be
       reloaded using ctlinnd before innd is unthrottled.  Editing it directly even with those
       precautions may make it inconsistent with the overview database and won't update
       active.times, so ctlinnd should be used to make modifications whenever possible.

       Each newsgroup should be listed only once.  Each line specifies one group.  The order of
       groups does not matter.  Within each newsgroup, received articles for that group are
       assigned monotonically increasing numbers as unique names.  If an article is posted to
       newsgroups not mentioned in this file, those newsgroups are ignored.

       If none of the newsgroups listed in the Newsgroups: header of an article are present in
       this file, the article is either rejected (if wanttrash is false in inn.conf), or is filed
       into the newsgroup "junk" and, when "Aj" is not set in the newsfeeds feed pattern, only
       propagated to sites that receive the "junk" newsgroup (if wanttrash is true).

       Each line of this file consists of four fields separated by a space:

           <name> <high> <low> <status>

       The first field is the name of the newsgroup.  The newsgroup "junk" is special, as
       mentioned above.  The newsgroup "control" and any newsgroups beginning with "control." are
       also special; control messages are filed into a control.* newsgroup named after the type
       of control message if that group exists, and otherwise are filed into the newsgroup
       "control" (without regard to what newsgroups are listed in the Newsgroups: header).  If
       mergetogroups is set to true in inn.conf, newsgroups that begin with "to." are also
       treated specially; see innd(8).

       The second field is the highest article number that has been used in that newsgroup.  The
       third field is the lowest article number in the group; this number is not guaranteed to be
       accurate, and should only be taken to be a hint.  It is normally updated nightly as part
       of the expire process; see news.daily(8) and look for "lowmark" or "renumber" for more
       details.  Note that because of article cancellations, there may be gaps in the numbering
       sequence.  If the lowest article number is greater than the highest article number, then
       there are no articles in the newsgroup.  In order to make it possible to update an entry
       in-place without rewriting the entire file, the second and third fields are padded out
       with leading zeros to make them a fixed width.

       The fourth field contains one of the following status:

           y         Local postings and articles from peers are allowed.
           m         The group is moderated and all postings must be approved.
           n         No local postings are allowed, only articles from peers.
           j         Articles from peers are filed in the junk group instead.
           x         No local postings, and articles from peers are ignored.
           =foo.bar  Articles are filed in the group foo.bar instead.

       If a newsgroup has the "j" status, no articles will be filed in that newsgroup.  Local
       postings are not accepted; if an article for that newsgroup is received from a remote
       site, and if it is not crossposted to some other valid group, it will be filed into the
       "junk" newsgroup instead.  This is different than simply not listing the group, since the
       article will still be accepted and can be propagated to other sites, and the "junk" group
       can be made available to readers if wished.

       If the <status> field begins with an equal sign, the newsgroup is an alias.  Articles
       cannot be posted to that newsgroup, but they can be received from other sites.  Any
       articles received from peers for that newsgroup are treated as if they were actually
       posted to the group named after the equal sign.  Note that the Newsgroups: header of the
       articles is not modified.  (Alias groups are typically used during a transition and are
       typically created manually with ctlinnd(8).)  An alias should not point to another alias.

       Note that readers.conf can be configured so that local posts to newsgroups with status
       "j", "n" or "x" are accepted.

MINIMAL ACTIVE FILE

       For innd to be able to start, the three groups "control", "control.cancel" and "junk" need
       to be in the active file.  Besides, if mergetogroups is set to true in inn.conf, the
       newsgroup "to" also needs to exist.

       The minimal active file shipped with INN is:

           control 0000000000 0000000001 n
           control.cancel 0000000000 0000000001 n
           control.checkgroups 0000000000 0000000001 n
           control.newgroup 0000000000 0000000001 n
           control.rmgroup 0000000000 0000000001 n
           junk 0000000000 0000000001 n

       (Note that the second and the third field may differ if the news server has already been
       in use.)

       There are more control.* pseudogroups here than needed by innd to start; the corresponding
       control messages will be filed into them.  The "n" status is so that users cannot post
       directly to these groups (control messages should only be posted to the groups that they
       affect).  If you do not want these groups to be visible to clients, do not delete them but
       simply hide them in readers.conf(5).

       To create additional groups after the server is running, you can use "ctlinnd newgroup".
       You can also synchronize your newsgroup list to that of another server by using actsync(8)
       or get the active file of another NNTP server with getlist(1).  And do not forget to
       update your newsgroups file, which can be automatically done thanks to docheckgroups
       called with the -u flag.
