IV. MAINTENANCE OF INN

 1. Adding new groups - see also Part IV, Section 3.b,:

     a. Type: "ctlinnd pause 'edit active'"

     b. Edit the active file.  The format is:
          groupname himark lomark flag.
        Set himark to 0000000000 and lomark to 0000000001.
        For detailed description of flags, read the man
        page for active.  Editing the active file by hand
        is easy, but will not update the information in
        that file active.times that some newsreaders
        require to trace new newsgroups.  Using ctlinnd
        command "newgroup" takes care of this problem
        (see below).  Editing the active file with an
        editor has one drawback - the file active.times
        is not automatically updated.  This creates problems
        for some newsreader (Trumpet being one of them) 
        that use this file to alert users to new groups.
        Using ctlinnd command "newgroup" (see Part IV.3.b)
        corrects this problem. 

    c. Run inncheck (see #11) to check the new active file
       for errors. 
  
    d. Type: "ctlinnd reload active 'new active'".

    e. Type: "ctlinnd go 'edit active'".


 2. New groups are sometimes added automatically through
    a control message.  A mail message to usenet will alert
    to such an automatic change to the active file.  If you
    do not want to subscribe to a particular news group,
    change directory to /usr/local/news and type:
      ctlinnd rmgroup <group name>

 3. Sometimes, a mail message will arrive for usenet with
    a checkgroups file.  Remove header, save the body of
    the message in:
      /usr/local/news/bin/control/news_control/news_control_
					todaysdate
    cd to that directory and type:
      ../docheckgroups <news_control_todaysdate
			 >todaysdate_pre
    Read the output file (todaysdate_pre) and carry out all 
    the instructions that you think pertain to your
    situation.  Read the man pages for "active" and
    "ctlinnd" for more info.  To implement the changes, you
    will have to change to the directory: /usr/local/news
    and:  
    
     a. remove a discontinued group:
          type: "ctlinnd rmgroup <group name>"

     b. add a group:
        type: "ctlinnd newgroup <group name> flag <creator
                                           name>"

     c. mark a group correctly:
        type: "ctlinnd changegroup <group name> flag"

    Run inncheck and repeat the docheckgroups command from
    the /usr/local/bin/control/news_control directory
    by typing:
      ../docheckgroups <news_control_todaysdate
                                >todaysdate_after
    Correct any reported problems.  Also, you may have to
    edit the /usr/local/news/newsgroups file to reflect
    any changes you introduced.

 4. Read the reports mailed to usenet (you) by the
    news.daily script.  Most errors are reported here and
    should be easy to fix.

 5. Subscribe to and read the following newsgroups:
      news.software.nntp
      news.software.readers
      

 6. IMPORTANT!!! Never run fsck on the drive where the
    /spool/news files are located while running INN.  Innd
    has a lot of active disk I/O going on and you could
    corrupt your drive. Use ctlinnd to throttle, pause, or
    shutdown innd first - see the manual page for ctlinnd.
