            DNEWS Installation, a brief guide by NetWin World
            -------------------------------------------------

DNEWS is a dynamic news server system, it is not a news reader but rather
it is the server which a news reader reads news from.

DNEWS is not freeware, see license.txt for details.

-----------------------------------------------------------------------------
(1) DNEWS Feature list:
    Dynamic sucking feed.
        A sucking feed may use as little as 10% of the normal
        disk space and network bandwidth.
        By only getting news items that people usually read
        very large savings are possible particularly for small
        sites & workgroups.  A hundred users can be supported
        on 100 MB depending on their reading habbits!
        I run a single user server on my NT as a background
        service, it's using less than 5MB.
    Flexible expire settings
        By allowing expiration by 'number of items' low volume groups
        become much more useful.  Also by allowing settings
        which change with disk space the system is much more
        stable to large influxes of news.
    Flexible access restrictions
        Reading and Posting access can be given separately to
        to different users and selections of news groups.
    Binarys available for common platforms
        On many platforms you do not need to build the binary
        yourself, e.g. VMS, (VAX & ALPHA), Solaris, Linux, Windows NT
    Email confirmation of posts
        DNEWS can be configured to send email confirmations as it
        sends items up to a main news server.  This gives users
        a clear record of a posted item and it's successful
        transfer into the 'net'.
    Items stored in a database
        Items are stored in a database which puts items together
        in blocks of 100.  This saves directory entries, inodes,
        and the empty space usually wasted due to blocking factors.
        Also file open and closes are minimized, this is essential
        on systems where this is a 'costly' operation, e.g. VMS.
    Compiling and porting relatively easy
        DNEWS was designed to be portable from the ground up, it
        does not rely on obscure UNIX features.
    Installation easy, totally configurable without recompiling
        DNEWS can be configured without recompiling and all
        the configuration scripts have been simplified where
        possible.
    Documentated
        A user manual is available.
    Supported
        EMAIL support is available for help with installation
        and management.
    Speed
        On comparable systems DNEWS typically out performs other
        news software, (even the likes of CNEWS and INN in some
        instances), other VMS news servers don't even come close.
        This is partly because DNEWS uses a more advanced database
        to store the news items.  The difference is also very
        noteable on smaller systems (e.g. Linux)
    XOVER implemented in software
        No xover database is created, the normal DNEWS database
        is fast enough to create this information 'on the fly'
    Streaming support
        Streaming NNTP extensions are built in.
    Strictly limited machine impact due to single threaded nature.
        DNEWS runs on a single process, this speeds up connect
        time as a process does not need to be created, and it
        self-limits the impact on the system.
Limitations:
    DNEWS does not store items in the same file structure as used by
    INN and CNEWS, so old software which accesses these files directly
    will not work.
-----------------------------------------------------------------------------
These instructions describe how to setup a sucking news feed, see the manual
for setting up a traditional feeding mechanism.
-----------------------------------------------------------------------------
(2) Installation VMS: (see below for UNIX and Windows NT)
    1) FTP the files from ftp.std.com ftp/vendors/netwin/dnews...
        extract.com    (ascii)
        install.txt    (ascii)
        dnews.bck_z    (binary)
    2) @extract      Extracts the required files from the saveset
    3) Modify REGISTER_USER.COM to register a user DNEWS$SERVER
    4) @REGISTER_USER.COM
    5) Modify DNEWS_START.COM to define the disks news should use.
       (don't run it yet!)
    6) $ edit sys$manager:systartup_v5.com    Add a call to dnews_start.com
    7) $ edit sys$sylogin:           Add the symbol, see dnews_login.com
    8) $ edit dnews_top:dnews.conf
        Modify the file DNEWS.CONF to describe your
          system by defining the following symbols
            SYMBOL        EXAMPLE
            manager        system
                    (email address or [e-mail])
            nntp_feeder    news.feeder.site
            myname        news.this.place
            timezone    nzst
                    (new zealand standard time)
            diskspace    100
                    (space available in megabytes)
            mail        smtp
                    (the foreign email protocol name)
            confirm        *.this.place  Enable email confirmation
                    when item is passed up to a feeder site.
    9) If your news feeder stamps news items with a name other than
        the ip name you specified above, then you will need to add an
        exclude field to the file newsfeeds.conf to prevent your system
        echoing all news back to the feeder!!!
        (check the path header of an item to see what it is doing)
    10) $ edit access.conf          Grant an ip range access to your users.
                    by name or number, e.g.
            *.this.place:read,post:::*
            161.23.4.*:read,post:::*

    11) $ @dnews_start           Start the system
         $ @dnews_login         (to define the symbol tellnews)
     The system will now try and get a list of news groups from your
       feeder site, while this is happenning it will not respond, but you
     can check it's progress by:
        $ type dnews.log
     When it has finished (give it 10-20 minutes), you can then try:
        $ tellnews status

    12) Go to a PC and try out your news reader software pointed
        at the new system.
-----------------------------------------------------------------------------
(3) Installation for UNIX:  (Sucking feed)  See below for Windows NT
    1) FTP the files from ftp.std.com ftp/vendors/netwin/dnews...
        dnews_MACHINE.tar.Z        (binary)
        (e.g. dnews_linux.tar.Z    )
    2) Extract to a temporary directory in your own account
        uncompress dnews_linux.tar
        tar -xvf dnews_linux.tar
    3) EDIT dnews.conf
        Modify the file DNEWS.CONF to describe your
          system by defining the following symbols
            SYMBOL        EXAMPLE
            manager        system
                    (email address or [e-mail])
            nntp_feeder    news.feeder.site
            myname        news.this.place
            diskspace    100
                    (space available in megabytes)
            df        The path and flags for df
            sendmail    The path and flags for sendmail
            confirm        *.this.place  Enable email confirmation
                    when item is passed up to a feeder site.
    4) Edit your system startup script, the name will vary:
        On LINUX /etc/rc.d/rc.local
        Add a line:
            /usr/local/dnews/dnews_start.sh
    5) If your news feeder stamps news items with a name other than
        the ip name you specified above, then you will need to add an
        exclude field to the file newsfeeds.conf to prevent your system
        echoing all news back to the feeder!!!
        (check the path header of an item to see what it is doing)
    6) Edit access.conf         Grant an ip range access to your users.
                    by name or number, e.g.
            *.this.place:read,post:::*
            161.23.4.*:read,post:::*
    7) If you have changed any of the default directories, then edit
       all the .sh scripts to reflect the changes.
    8) Run the installation script
        su root   (You need priv to install the files start dnews)
        ./install.sh
    9) Start the system
        ./dnews_start.sh
     The system will now try and get a list of news groups from your
       feeder site, while this is happenning it will not respond, but you
     can check it's progress by:
        more dnews.log
     When it has finished (give it 10-20 minutes), you can then try:
            > tellnews status

    10) Go to a PC and try out your news reader software pointed
        at the new system.

    LINUX slackware: Comes with a dummy nntp daemon installed, you must remove
    this so dnews can bind to the socket.  (so it
    won't even start up)
        edit /etc/inetd.conf
        (comment out the NNTP line)
        kill -HUP <pid of inetd process>

    Some brands of unix (BSDI, Unixware) have process limits, the
    two that will hurt dnews are memoryuse/datasize, and
    openfiles.  The following commands can remove these limits
    you will need to do this for root and news users.
        limit memoryuse unlimited
        limit openfiles 256
        limit datasize unlimited
    To test these limits are really removed use the commands:
        tellnews test_mem
        tellnews test_files
    You must stop and restart dnews after running these tests.
    You should see about 200 free file handles and about 30MB or more
    of memory that can be allocated, if you see less then you haven't
    removed the limits.


-----------------------------------------------------------------------------
!!! Notes for Windows 95 !!!
  Follow the instructions for Windows NT and mostly it will work
  except for:
      1) Services don't exist, so you have to run dnews from a
         DOS prompt.  You can put this into your STARTUP group to
         make it start automatically like an NT service.
      2) The DNEWS MANAGER start and stop service buttons won't work.
         You can stop the service by sending the EXIT command, it
         may give an error when you do this, but check the log and
         it will probably show it has shut down.
      3) NetWin do not recommend the use of Windows 95 as a full
         news server for large numbers of users. Use NT if possible.

---------------------------------------------------------------------
(4) !!! UPGRADING NT!!!
    Shutdown the server and exit from DNEWS Manager
    Run the self extracting archive
            dnews23c.exe (or whatever version)
        When installation is complete start DNEWS Manager
    from the DNEWS Program Group. And click on
            'Start Service'

(4) Installation for Windows NT !!! on a new system !!! (Sucking feed)
    1) FTP the files from ftp.std.com ftp/vendors/netwin/dnews...
        dnews23c.exe (binary transfer)
    2) Run the self extracting archive and installation
           procedure
        dnews23c.exe
        3) Run DNEWS Manager to modify the setup further
           and to start the service
    4) Point your news reader software at your NT and try out your new
        fast news system.

    5) Join the mailing lists for advice an update information,
     and don't forget to register :-)
            Open DOS Window
            then type TELLNEWS REGISTER


    If it fails, look in
        type \dnews\dnews.log
    Then check the FAQ file DNEWSFAQ.TXT
    Then send email to us if you think you've found a bug, or to
    the mailing list if you just want advice from other DNEWS
    managers.
-----------------------------------------------------------------------------
(5) Installation for NETWARE 4.x
WARNING: MEMORY
  DNEWS expects virtual memory, as netware has none you
  have to make sure your system has sufficient REAL memory,
  for a sucking feed you will need 8MB free, for a full IHAVE
  feed you will need 16MB of free memory (these are estimates)
WARNING: GROUPS
  This release for NETWARE is limited to 10,000 groups,
  this is heaps if you take care with the 'ME' setting
  in feeds.con
WARNING: BETA RELEASE
  This is a beta release, NetWin do not recommend that you
  install this on a mission critical server.  Please report
  any problems you find.

    attach myserver
    File, Run, dnewsnw23f.exe  (or whatever the latest version is)
    Answer the configuration questions.

    In your autoexec.ncf script add the following lines.
        load dnews
    Load the server by hand.
         load dnews

    Go to a PC and try out your news reader software pointed
    at the new system.  On windows 95 you can run the DNEWSMAN
    configuration utility to setup or modify your configuration.

    Use the command:
        load tellnews status        To see what it's doing
        load tellnews register        To see what it's doing
        load tellnews exit        To shutdown dnews nicely
        load tellnews help        For other commands.

    NEVER shutdown the service with the 'unload' command. Always use
        load tellnews exit
    instead.


-----------------------------------------------------------------------------
(6) Installing a full feed:

In access.conf, give your feed site access to send you ihave messages:
    my.feeder.site.com:ihave:::*
In dnews.conf, comment out the nntp_feeder definition and add a line:
      cachedall true
In newsfeeds.conf
    Replace
        site $NNTP_FEEDER
            groups *
            builtin
            posting
    With
        site my.feeder.site
            groups *
            builtin
    And correct the ME feed, the default one does not
    allow any binary groups in, if you really want a
    full feed fix this by removing the !*binary*

**** You must get an active file ***
You MUST get a copy of active.dat from your provider, the file is simply
called the 'active' file on INN or CNEWS, you need to FTP the file and copy it
to \dnews\spool\active.dat while the server is NOT running.

Copying important files from an existing system:
    With a sucking system you can do this with the commands:
        tellnews getnames
    The active file will be fetched automatically.  But if you are setting
    up an IHAVE feed so you don't have 'reader' access this WILL NOT WORK, you
    must FTP the active file from your provider if possible, or from
    ftp.std.com /ftp/vendors/netwin/dnews/active.dat_sample and copy it
    to  /dnews/spool/active.dat  (the workarea directory)

    If you are replacing a news system then you want
    the active file from the one you replace, not from your
    feeder site:

    You can safely copy these files:

    active        -> active.dat
    active.times    -> active.times
    newsgroups     -> active.names  (may be changed in future)

    If you copy the active file, you must reset it so that
    it doesn't think it has any items, do this with the command
        tellnews resetall

     The only way to get the actual news items from an existing system is to
    setup DNEWS on a second system (or on the same system on a different
    PORT) and then suck the entire database via nntp.  Obviously to do this
    you need a lot of free disk space.

Renaming a volume (on unix):
    You may wish to rename a current volume /var/spool/news
    to be /var/spool/dnews, to do this:

    cd /var/spool/news
    mkdir OLD
    mv * OLD
    umount /var/spool/news
    emacs /etc/vfstab (or /etc/fstab)
        (change /news into /dnews)
    mount /var/spool/dnews

    When you are happy with the new system, or you need the space:

        rm -r /var/spool/dnews/OLD


(XMIT (Setting up full feeds)
    This is necessary when you want to send a full feed onto another site.
    If you are a leaf site then you DONT NEED TO DO THIS !!!!!!
    First add entries to your NEWSFEEDS.CONF file, this creates the
    file site_name.feed, then you need to setup a timed job to send those
    items to the other sites using NNTP IHAVE (or streaming extensions)

    You should set all groups as cached, in dnews.conf add  a line:
             cachedall true

XMIT (On unix)
    Add lines to your rc.local procedure, e.g.
        cd /usr/local/dnews
        ./xmit send.to.site.name -at "*2" "*"
        ./xmit send.other.site.name -at "*7" "*"

XMIT (On Windows NT)
    On windows NT you need to setup each xmit job as a service, to do this
    use the program ADDSVC.EXE which came with the dnews distribution to
    add a service for each outgoing feed, e.g. (see setupsvc.cmd)
        addsvc -add dxmit1 xmit.exe "dxmit1 site.name.edu -at *5 *"
        addsvc -add dxmit2 xmit.exe "dxmit2 site2.name.edu -at *5 *"
    Then from CONTROL PANEL, SERVICES, and start the feeds.

XMIT (On VMS)
    See RUNXMIT.COM

------------------------------------
(6b) Example of full feed from UUNET


-------dnews.conf---------
In  dnews.conf  comment out nntp_feeder by putting a HASH in
front of the line, and add cachedall true, e.g.
    # nntp_feeder    your.feeder.ohio.edu
    cachedall true

------newsfeeds.conf cut here ----------
    site me
        groups *
    site news.uu.net
        groups *,!local.*
        exclude uunet
    site YOUR.MAIL.GATEWAY
        smtp
------access.conf cut here and change your domain and ipnumbers ------
# Don't let the world connect :-)
*:logoff:::*

# Do let your domain and ip range connect    **** CHANGE THIS BIT ***
*.your.domain:Read,Post:::*
161.232.32.*:read,post:::*

# Do let your news feed from UUNET send you items
news*.uu.net:ihave:::*

    Setting up a UUCP feed out of DNEWS
    Setting up a UUCP feed into DNEWS
        Message aren't going upstream/ 435 Duplicate error

Calculating memory use
    This is a rough guide to calculating how much memory
    dnews will use.  This is VIRTUAL memory, you dont' need this
    much physical memory (but it will go faster if it does :-)

        (Concurrent connections) * 200K
        (Articles in history file - see expire processed) * 12
        (Spool Gig's) * 1MB
        (Max article size accepted) * 2
        (Number of news groups) * 100
        head_cache (default 200) * 3k
        xover_cache (default 3000) * 300
        Program static data 4mb

    So lets take a smallish system with 20,000 news groups,
    10 concurrent connections, 200,000 lines of history data,
    1 Gig of spool, 1MB articles.

        10 * 200K = 2MB
        200,000 * 12 = 2.4MB
        1Gig = 1MB
        1MB Artilces = 2MB
        20,000 News groups,  = 2MB
        head_cache (default 200) * 3k = 600K
        xover_cache (default 3000) * 300 = 900K
        Program static data = 4mb
        Total memory use = 14.9MB
    NOTE you DO NOT NEED THIS MUCH RAM, dnews is designed to
    deal with multiple full feeds and 100's of users, if you
    are running a smaller system you don't need all this as REAL
    ram, that's what virutal memory is for, it just slows down
    a little.

    Typically on a small system where you wish to reduce the
    memory use you need to look at:
        Total groups
        History remember setting.
        Maximum article size

    You can drastically reduce memory use with these settings:
        (in expire.conf) remember 4
        (in dnews.conf) item_max 200000  (stops large binary items!!!)
        (in newsfeeds.conf change your ME feed to only
        allow groups that really exist in your country-area)
            site ME
                groups !*,rec.*,comp.*,alt.*,news.*,soc.*,bit.*,bionet.*,sci.*
        tellnews matchfeed
        tellnews purgegroups
        (restart dnews to free up the memory)

    As a rule of thumb to avoid calculations with unix and NT,
    create a 100MB swap/page file as a first step.  If you
    are running a big system, then 200mb would be a wise choice.

Setting your EXCLUDE parameter correctly:
     In newsfeeds.conf you must set your exclude parameter to
    stop DNEWS from sending incoming messages back
    to your feed site.  Lets assume your feed site is
    called fastfeed.world.net. You need to find out what it
    stamps onto news articles, to do this read a news article
    (and show all headers so you can see the PATH header)

    e.g.
    Newsgroups: alt.winsock.trumpet
    Subject: Sportster Si does not seem to work with TRUMPET
    Date: Thu, 26 Oct 1995 22:44:08
    Organization: Personal
    Lines: 8
    Message-ID: <[e-mail]>
    NNTP-Posting-Host: eagle28.sasknet.sk.ca
    X-Newsreader: Trumpet for Windows [Version 1.0 Rev A]
    Path: fast1.world.net!world.net!news.icix.net!esol.intermedia.com

    Look thru the path, left to right, and find the first or most generic
    name for your feed site, in this case 'world.net' looks like
    the best name to choose.

    So here is the entry you should put in newsfeeds.conf, you may
    need the builtin and posting settings as well but that is up to you.

    site fastfeed.world.net
               groups *
        exclude world.net
        builtin

    You may need to delete your .feed and .sending
    files from the spool directory to clear out
    the backlog of articles queued.

Posting to a moderated group
    Note: You can only do this to your own moderated local groups.
    Get the FreeAgent news reader.
        In agent.ini change showallfields to 1, e.g.

        [Message]
        ShowAllFields=1

    Then re-post the article after putting your mail address
    in the approved header using freeagent.

    ftp.std.com ftp/vendors/netwin/dnews/dnewsdoc.zip

HINT: when reading the log files, it is easy to confuse an error message
from DNEWS with an error message that dnews got while talking to
your feeding site.   Usually if the error looks like:
   Status {223 transfer permission denied}
then it came from somewhere else, not your system.

Can't BIND, and tellnews sais "I can't talk to you"
    LINUX slackware: Comes with a dummy nntp daemon installed, you must remove
    this so dnews can bind to the socket.
        edit /etc/inetd.conf
        (comment out the NNTP line)
        kill -HUP <pid of inetd process>
TELLNEWS fails
    The DNEWS process may take 1-2 minutes to initialize, so wait a bit
    before panicking.

    Check if the process is running
        (linux) ps -axl | grep dnews
        (sunos) ps -ef | grep dnews
        (nt) Look at services in control panel

    Check the log files
        more /usr/local/dnews/dnews.log
        (nt) type /dnews/dnews.log

    If it gets started up with the wrong PID you will get all sorts of
    protection problems,  all the files in
        /var/spool/dnews/...  (including var/spool/dnews)
    must be owned by the same user, normally 'news'
    Also all the files in:
        /var/local/dnews/*
TELLNEWS gives unusual error message
    On vms, if the symbol tellnews is not defined, it will try and run
    telnet instead, this can be confusing.
    On Windows NT if you left the disk name out of the config file and
    you run the tellnews command from a different default disk then
    it won't be able to find all the files it needs to work.
TELLNEWS GETOLD * gives a core dump
    Try
        tellnews getold "*"
    Need I say more?  This gets me every time too :-)
Transfer permission denied.
    This can come from one of two directions,  DNEWS can give this error
    when a site tries to feed it new items.

    If you are using a sucking feed then you should stop the
    site that is trying to send to you from sending as DNEWS
    will ask for any items it wants.

    If you do want to allow incoming IHAVE messages,
    then add an IHAVE record for this ip address in the
    ACCESS.CONF file, and also remove the 'POSTING' flag from
    the NEWSFEEDS.CONF file for the ME site.

    The last possibility is that this error is coming
    from your feeding site, in which case that system manager
    has to fix the problem for you.
Creating local news groups:
    If you wish to have local groups on your server, that are not on the
    server you 'suck' from, then you should remove the 'POSTING' flag
    from the feed to your feeder site (in newsfeeds.conf).  But
    only if you can get ihave or transfer permission to send
    articles up stream rather than simple 'posting' access.

    You can add groups with the TELLNEWS NEWGROUP command, e.g.
        tellnews newgroup here.chat y myname Local group for chatting

        here.chat = name of group
        y = Normal group (m = moderated)
        myname = Just a record of who created the group (one word)
        Local group for chatting = description for active.names file.

    To stop your local group from being sent up stream, you would
    change the line in your newsfeeds.conf file:
        groups *,!here.chat,!here.secret.*
    NOTE: KNOWN BUG, with version 2.0 items will still be sent upstream if
    you have left the 'POSTING' keyword in your feed.  This will probably
    be fixed in a future version

Giving DNEWS access to an INN news system.
    1) Give normal NEWS READER access to the dnews machine by adding a
    line to your nnrp.access file
             dnews.ip.name:read post:::*

    2) Give DNEWS ihave access to your server
    Add a line to  hosts.nntp
            dnews.ip.name

What if DNEWS Crashes !!!
    Don't Panic! (in large friendly letters)
    It is a design goal of DNEWS that it should never never never
    never never crash.

    We have now built in some special debugging options so you can
    help us track down the problem if this should happen on your
    machine.

    So, if it crashes, do this:
        Edit dnews.conf and change the debugging lines to:
            loglvl flush
            debug_rotate 2000
    Then start the system, and the next time it crashes, email
        dnews.log  & dnews.conf & newsfeeds.conf
    To us at:  [e-mail]
    Together with any other facts that you can give us, e.g.
        If you are sucking news or getting a full feed.
        If you are using xmit
        What systems and news readers are reading from you,
        (e.g. tin, trumpet, pc's only, whatever...)
        At what time of day it crashes. any other clues...

    Many thanks for your assistance in this.

Gatewaying Mailing Lists
    CAUTION, gatewaying mailing lists to public news groups is
    a little risky, don't do it lightly.

    Two gateways are needed to make a news group and a mailing list
    'identical', you must setup both so that a news post gets sent to the
    mailing list and so a mailing post gets posted to the news group.

    Setting up a gateway from a "NEWS group" to a "MAILING LIST"
        In newsfeeds.conf add a feed for the group you wish to gateway, the
    'site' name can be anything meaningful to you.

        site juggling
                groups rec.juggling

    (This will make dnews create juggling.feed in the workarea directory)

    Now to actually send the items, setup an xmit process for each mailing
    list.  To do this edit addmail.cmd (which will be in /dnews with luck)

    notepad addmail.cmd
        Change the -name to be the name in newsfeeds.conf
        Change MAIL.HERE.COM to point to your mail server
        Change [e-mail] to point to the actual mailing list
        addsvc -del dxmail1
        addsvc -add dxmail1 xmit.exe "dxmail1 MAIL.HERE.COM -at *5 *
(cont. but should be on one line)   -mail [e-mail] -name juggling"

    addmail.cmd  (run the script to add the service)

         Restart things:
         tellnews reload
         Start the xmit service in Control Panels (for nt)

    Test the mailing list, if a loop occurs, disable it quickly and figure
    out why.

    Setting up a gateway from a MAILING LIST to a NEWS GROUP  (Windows NT only)
        First setup DROBOT to run from ntmail, in control panels run the
    NTMail admin tool.  Click on 'executables' and enter a name for this
    gateway, e.g.
        juglist-robot
    (You will then need to add this user to your juglist mailing list, e.g.
     [e-mail], so that this robot will get all messages that
     are posted to the mailing list)

    In the command line box type in:
        drobot -dir c:\ntmail\news -groups rec.juggling

    Now, setup the service to post these items.
        addsvc -del dposter
        addsvc -add dposter dposter.exe "dposter -dir c:\ntmail\news
            -to news.here.com"

    Now start the services (from control panel) and then test
    posting a message and mailing a message to the mailing list and
    see if the newsgroup and mailing list are kept inline.

Windows NT operating system bug

>Situation:
>- In ControlPanel->Network->Server->Configure the optimization is set by

Setting up a UUCP feed into DNEWS
    In dnews.conf add
        suck_uucp c:\uucp\in\*.bag

    The BAG/UUCP file format is:

    #! rnews nnnn
    ...(article, exactly nnnn bytes, counting each end of line as one byte)
    #! rnews nnnn
    ...(next article)...

Setting up a UUCP feed out of DNEWS
   In newsfeeds.conf add a feed, e.g.
               site site1.name.uucp
            type uucp
            uucp_dir c:\uucp\out
                   groups *


   This will create files called news000n.bag in the directory c:\uucp\out
   It's your job to uucp copy these to the destination sites, and delete them.
   If you want you can compress them first.  :-)

   The format of the file is:

    #! rnews nnnn
    ...(article, exactly nnnn bytes, counting each end of line as one byte)
    #! rnews nnnn
    ...(next article)...


Message aren't going upstream/ 435 Duplicate error
        The problem is your exclude paramter is wrong, this
    results in dnews sending all items it gets back upstream
    which results is a clogged queue so your local posts
    never get sent.

    Read the section above:
              Setting your EXCLUDE parameter correctly:

-----------------------------------------------------------------------------
(9) Using other TCPIP stacks on VMS
-----------------------------------
    Only the multinet driver has been tested.  The ucx driver has been
    compiled and will probably work with very little effort.

To build a new TCPIP driver:
    $ edit nntp.c
    (Add a section to include the header files for your version
    of tcpip, ifdef it in some obvious way). e.g.
        #ifdef MULTINET
            #include "multinet_root:[multinet.include.sys]socket.h"
            ...
        #endif

    $ edit n.com
    (Change the compile line so it defines the symbol that you
    used above to distinguish your tcpip software AND change the
    name of the object file too) e.g.
        $ cc nntp.c /define=("MULTINET"="TRUE") /obj=nntp_multi.obj

    $ edit l.com
    (Add a section to link to your tcpip stack, you will need to change
    the name of the nntp_XXX.obj file name and probably the socket library
    name.)

    Try and compile it and link it:
        $ @N
        $ @l multinet all

    Most likely it will fail because of some conflict between names
    e.g. socket_close(), or simply close(),  add ifdefs to NNTP.C to
    correct for this.

    Once you have it working, email the files nntp.c and l.com and n.com
    to us and we will maintain and distribute these changes for
    others.

(11) Notes on compiling and porting DNEWS (unix)
------------------------------------------------
    Uncompess and untar the saveset
    Copy a config file which matches your machine, if one does not match
    then find the closest one you can. e.g.
    (for SunOS)    > cp config.solaris config.i
    (for LINUX)    > cp config.linux config.i

    Edit and modify config.i as necessary.
    Type in make all.
            > make all
    Now follow the normal installation instructions.

    If you have to make changes to the config.i file, then email it to
    us, specifying what type of machine & OS it is for and we
    will include it in the next distribution.

    If you change source code then email us the entire source files
    that were changes, please don't send diff or patch files these
    are extremely difficult to merge from multiple sources.

    When making machine specific changes, IFDEF all the changes
    and where possible use 'feature' like ifdefs rather than
    'machine' related ifdefs, e.g.

        #ifdef NEEDS_STRDUP
            ...
        #endif
    (then define NEEDS_STRDUP in the config.i file)
    Rather than:
        #ifdef LINUX
            ...
        #endif

Enabling the DNEWS Full Text Searching engine
---------------------------------------------
Warning: This is a beta release of the Full Text Searching mechanism which
was more than a little difficult to implement, it is still experimental at this
time! We will be keen to hear how it performs in the 'real world' your feedback
is always valuable.

Warning!!! To build a really complete index will require free space
of about 10-50% the size of your spool area, it will also gobble up
signficant processor & memory resources.  See the file fts.conf to control how
much of each item is actually indexed, and limit the list of groups that
you send to the indexing service.

You can 'index' a subset of groups, possibly just your local
news groups which are important to you, this will require very little
resources.

What to do:
    1) In dnews.conf define the directory to use to build indexes, it
       must be a disk with lots of free space :-)
        fts_dir c:/dnews/fts           (NT)
        fts_dir /var/spool/dnews/fts   (Unix)
    2) Create the directory and move or copy fts.conf into it.
        (NT)
          mkdir c:/dnews/fts
          copy /dnews/fts.conf c:/dnews/fts
          del /dnews/fts.conf (so you don't mix it up with the real one)
        (UNIX)
          mkdir /var/spool/dnews/fts
          copy fts.conf /var/spool/dnews/fts
    3) Install an xmit service to build the indexes:
        (NT)
          addsvc -del dfts
          addsvc -add dfts xmit.exe "dfts ftsfeed -fts -at *5 *"
        (UNIX)
          nohup xmit ftsfeed -fts -at "*5" "*" &
          (put that in a startup file)
    4) Add an ftsfeed to newsfeeds.conf to send items to the xmit service.
       Select a list of groups that seem sensible to index, don't index
       the binary groups :-)  (add this to the end of newsfeeds.conf)
        site ftsfeed
            groups !*,comp.*,rec.*,local.*
    5) Install dnewsweb, and in dnewsweb.ini tell it that fts is enabled
        search true
    6) From Program Manager start the xmit fts service:
        In Control Panel, Services, Start the DFTS Service
        (UNIX) nohup xmit ftsfeed -fts -at "*5" "*" &
    7) Wait for the indexes to start being created, if you have a small
       system you might want to send your current items into the database
       we DO NOT RECOMMEND using this command, it WILL lock up dnews
       for several minutes:
            tellnews refeed ftsfeed   (DO THIS AT YOUR OWN RISK)
    8) Try the system out:

    Notes:
        1) New items will not appear immediately as DNEWS does
           not reload the database very often.

(12) Updates, List of bugs/features for each version.  (in reverse order)
-----------------------------------------------------------------------------
2.7p
    + Fixed error in newgroups date processing.
    + Made uucp_suck more flexible if rnews lengths are not exactly correct
    + Fixed bug with maxsize limit for individual feeds
    + Fixed bug in Full Text Searching on non NT systems (causing crash in xmit)
2.7o (12-Nov-96)
    + Wide release of beta
2.7n
    + Expire speeded up, on a large system (15 Gig spool area) we
    measured it went from 10 hours to 2 hours.  Your mileage may vary.  :-)
     + FTS patch
    + Database flushing modified.
2.7k
    + used.log file moved to log directory, and renamed to
      u_yymmdd.log this is to make accounting procedures simpler.
      Also the full date has been added to each line inside the file
      as well as the size of the article read.
      We applogize if this breaks any existing software.
    + If reverse dns produces a hostname with no '.'s in it, then
      the ip number is used to tag local posts instead of the name.
    + Added dnews.conf paramter STR_START this defines the inital string
      space, you can use this to tune dnews, after it's been running for
      a few days check the second value in the str memory use shown in the
      status output, e.g.   History:... Str 6040k/7050k/10060k
      Use a number larger than the second number.  Add 1 or 2MB e.g.
          str_start 8000000
      Don't use this parameter on WINDOWS NT, it isn't needed.
    + newsfeeds.conf parameter PENDING_MAX added, the default is 10000000 (10mb)
      If a feed file gets larger than this setting it is automatically
      deleted, this helps to support many outgoing feeds where often one
      machine is down for several days and you don't want to run out of
      disk space.
     + Added variables to newsfeeds.conf $nntp_suck2...$nntp_suck4
    + Updateone now inserts new items 'above' normal items in the que, in this
      way you can schedule some groups to be updated at a higher priority by
      setting up a cron job to issue a command
           tellnews updateone "rec.humor.*"
    + Fixed occasional synchronization loss with live feeds on large items
    + Fixed loop in streaming sucking (introduced in 2.7)
    + Fixed rare bug in hist_hash() which could cause crashes with very long
    message id's.
    + UUCP files flushed before reload to prevent errors.
    + Fixed live feed of missing items to ANU news server. (Feeds would block)
2.7j
    + in_size added to dnews.conf, set to 500 if you are trying to
    limit the speed of incoming messages via a modem.
    + fixed bug if live feeds with rejected items
    + fixed bug in live feeds with very long message id's.
2.7i
    + Bug fixes in feeding channel closes
2.7h
    + Fixed bug in uucp caching.
    + Fixed rare crash bug in live code.
    + Fixed bug with item_max being exceeded with streaming feeds
2.7g
    + Modified 'resetall' so it doesn't set all groups to cached.
    (warning, NEVER user RESETALL on a running dnews server, it is only
    intended to be used during the initial installation)
    + Added tellnews command  logchan n  and  logfeed  feedname
    Enables logging of that channel/feed to a file chan_n.log
    + Improved speed of uucp outgoing feeds and normal multiple outgoing
    feeds.
2.7f
    + Fixed crash if live channels are closed in mid message.
2.7e
    + Fixed problem with builtin uucp feed not writing enough items to each file.
    + Fixed bug with multiple sucks for identical groups if they were
    scheduled to run at the same times.
2.7d      + Added dnews.conf setting tcp_nodelay true, this will slow dnews down
    but may solve problems with buggy news readers (as it stops packets
    being split up in mid record)
    + Fiddled newgroups command output to make Newswatcher happy.
    + Fixed live feeds to INN 1.4unoff4
    +
2.7c
    + Added dnews.conf setting uucp_crlf which writes uucp bag files
    with 'crlf' (text mode) instead of just 'lf' termination.
    (changed default to 'lf' termination for unix compatibility )
    + Fixed bug with dnewsman rejecting uucp_size and uucp_n settings.
2.7b
    + Fixed bug rejecting items if item_max exceeded.
    + Made item_max dynamic (i.e. a reload changes it :-)
    + Added NNTP extension 'LIST SUBSCRIPTIONS' sends the file
       dnews/spool/subscrip.dat
      This is typically a list of default news groups that you wish
      new users to be subscribed to.  (Not all news readers will support
      this function yet).
2.7a
    + Major features of 2.7a
        + Lower memory use
        + Live high speed outgoing feeds (to replace xmit) these stream
          and allow multiple channels, and send articles as they are
          received to reduce system impact.  This makes DNEWS ideal
          for easily sending out large feeds to many customers.
          (Assuming they haven't seen the light and switched to
          sucking feeds yet :-)
        + Support for writing UUCP files directly (much faster)
        + Support for reading UUCP files directly (much faster)
        + Shotgun posting, to spread your local posts faster.
        + PIDENTD support for unix systems.
        + Many minor improvements / config settings / management commands.
    + Before playing with the new commands for removing groups, copy your
      ACTIVE.DAT file (just incase :-)
    + tellnews group_nodup  removes duplicate groups if they exist
    + Reduced memory use of large incoming items especially from multiple
      ihave feeds
    + Reduced memory use of group information.
    + Increased OS2 open files to 10, You should put FILES=40 or more
      in config.sys  (Thanks to Jean-Louis Noel for OS2 code fragments)
    + Print error if history file is unreadable
    + uucp output is now a builtin option for dnews, in newsfeeds.conf
        site uucp1
            groups *
            type uucp
            uucp_dir c:\uucp1
            uucp_size 4000000
            uucp_n 500
      This will create bag files in the uucp1 directory, and switch every
      4MB or 500 items.
    + Live links for sending out feeds.
        site downstream.site.name
            type live
            live_nchan 3
            groups *
    + On unix, err closed = 150, on slow sucking feeds fixed.
    + Change to license key processing (2-4) while waiting for key entry.
    + Fixed bug in the '.in' log files rotated file names
    + Added tellnews command
        tellnews trimgroups [n]
      which removes groups from your local machine that are not
      available on the machine you suck from.  (n is the suck number)
      After doing this check dnews.log,  then use the purgegroups command
      below if necessary.  BEFORE doing this make sure your list of
      groups in nntp_feeder, or nntp_suck2-4 excludes your local groups
      or they too will be deleted (if you mess this up then use the
      undelete command from tellnews to get them back)
      e.g.
                 nntp_feeder main.sucking.site *,!microsoft.*,!local.*
                 nntp_suck2 msnews.microsoft.com !*,microsoft.*
    + Added tellnews command
        tellnews purgegroups [wildcard]
      'kill' groups that have been marked for delete.  This command sets them
      to actually be forgotten.  Always restart dnews after using this
      command.
      Note: If you do this on a sucking feed where you have removed several groups
      by hand that 'do' exist on the site you suck from, then the groups
      will re-appear.   This is because dnews adds groups it doesn't know about
      when sucking.  They should be left as 'marked for delete' if you don't
      want them to re-appear.
    + Added tellnews commmand
        tellnews checkgroups check.txt
      This processes a file check.txt, which must be a checkgroups message
      with header lines followed by one blank line, followed by the list of
      news groups with descriptions.
      Missing groups will be added, extra groups will be deleted.
    + Added support for checkgroups control message.
    + Problem with cachedonly true and sucking fixed  (items were
      rejected until the user read an item )
    + Added support for pipe based programs to accept feeds directly from dnews.
            site prog1
            groups local.*
            type program
            prog_name \dnews\darchiv
            prog_args \dnews\darchiv.log

      When items arrive a pipe will be opened to the darchiv program, which
      must read articles from stdin and do something with them.  The articles
      are sent in the following format:

        ARTICLE group:item_number <messageid>
        (Actual header and body of article)
        .  (single full stop is end of article)
        ARTICLE group:item_number <messageid>
        (Actual header and body of article)
        .  (single full stop is end of article)

      A sample 'c' program is provided in this file to assist you
      in writing or modifying existing software.

    + Tellnews killitem (modified to show if it succeeds)
    + expire_minutes, bug fixed
    + Decreased group_write to 10 minute intervals
    + Improved output of chan[] status lines. e.g.
      Chan[0:72] B o=0 in=54/s out=2788/s 161.29.2.1 161.29.2.1 C_CMD
       B     The channel is busy processing a command
       o=0  No bytes are waiting to be sent
       in=54/s The channel has been reading at about 54 characters / second
       out=2788/s The channel is writing at about 2788 per second.
    + LOG_AGAIN true,  Creates second log file using unxi fflush() that
      never closes (purely for debugging use)
    + Fixed tellnews log command if log file is empty
    + Added channel closing logic for outgoing channels.
    + Mail messages will now be sent even if the suck queue is paused.
    + Added log_inline (default true, item ok messages in log file)
    + Added log_nntp (default true, nntp commands in log file)
    + Tellnews status feed[] now shows the size of the waiting feed file.
    + ADDEd dnews.conf
        org Your Company Name
    + Added dnews.conf
        org_replace true  (forces your organization name on all posts)
    + Added tellnews command   reject <messageid>
      which will somtimes be useful in unblocking blocked feeds.
    + Increased max_chan to 800, this may allow up to 800 concurrent sessions
      on a machine with enough RAM etc...
    + Added output bandwidth limiting.  MAX_OUT 10000
      Controls bytes/second per channel
      A value of between 2000 and 30000 is sensible.   (3000 would limit
      connections to 'modem speed')
    + Changed mail processing so messages are sent immediately
    + Made suck automatically fix upto counters if they are too high.
    + If posting feed fails to connect, it shouldn't retry straight away, this
      should allow the suck'ing to continue from an alternate host.
    + Dnewsweb: Now requires subject header's for post
    + Shotgun posting
      It is now possible to 'shotgun post' using the 'posting' mechanism
      as it will send to ALL matching feeds in newsfeeds.conf.
    + Routing messages into a posting feed, Set
          post_route true
      and then incoming 'ihave' messages will be routed to outgoing
      posting feeds.  Do this at your own risk, it is somtimes justified,
      for example if you have a BBS running 10 groups attached to your
      dnews server then it may need to send into your machine via IHAVE and
      you need to 'route' the messages upstream.
    + DNEWS now responds correctly to cancel messages, it previously
      gave a 'rejection' status if the message did not exist locally, although
      reasonable this is not 'normal' behaviour so we have changed it to
      match other news servers.
    + DNEWSMAN upgraded to allow all the new feeding options
    + Minor changes to sucking logic
    + Added to dnews.conf pident authentication
          pident true
      Which if tells dnews to attempt to verify a 'username' for every
      connected session.  (This is only meaningful on unix systems where
      the 'ip address' alone does not identify the user) If successful then
      the users name is added to any message that they post.
        + Fixed bug with nntp_feeder being undefined causing lockups.
    + Fixed bug if expire encounters history line over 8K long.
    + Added dnews.conf parameter
        suck_uucp c:\uucp\*.bag
      This replaces the dposter service for reading in uucp feeds, it
      will read in messages a LOT faster than the dposter service could.
    + New command tellnews disconnect n, where n is the channel number
      shown in tellnews status.
    + Fixed bug with solaris closing channels for no reason.
    + Fixed intermittent bug in expire if usage was over 89%
2.6q
    + Patch for dnewsweb for BSDI and OSF
    + Added dnewsweb.ini setting
        cgi_path dnewsweb
    This parameter is needed with some CGI wrapper programs
    which fail to pass the correct path thru.  The above
    example will usually fix it.
    + Added code to deal with buggy select call in solaris
2.6o
    + Fixed xmit to mailing list gateway, it was not sending once it
    got an error.
    + Reduced number of open files in OS2, their is a limit of 8 for some
    unknown reason in the watcom C library.
2.6n
    + Minor mod to db code re expire processing.
    + string compress fix for non nt versions
    + built new OS2 version, dposter should work now.
2.6m
    + Forced addition of posting host header.
    + Increased timeout from 26 minutes to 1 hour if history.dat is locked
    (for example by a slow backup process)
    + Fixed a bug in the refeed command.
2.6k
    + Fix for tellnews group_merge command, the groups in the active.add
    file were not being added to the active.times file.
    + Fixed bug in email confirmations and reports
    + Fixed refeed command so it runs without stopping dnews
    + Added tellnews log [nnn] to show the last few lines of the log file.
2.6j
    + NOTE: you must delete *.fts before starting this new FTS system if
    you were testing the previous beta version of FTS. (full text searching)
    + FTS system re-written to improve performance. Warning it still uses
    a LOT of memory, figure in 20MB's if you want to index everything.
    + Fixed bug in the xmit restart after crash code.
2.6i
    + If you create a file post.add in the config directory
    it will be appended to all local posts (use at your own
    risk of attack from free thinking users :-)
    + Reduced memory use on NT.
    + Fixed bug with sending articles out via combined ihave/suck feed.
2.6h
    + Fixed response codes from tellnews, always end in 281 now.
    + Fixed bug in FTS which could cause a crash (only if you were
    using fts)
    + Improved performance of cancel messages (by a large factor)
    + tellnews killgroup modified to always delete groups even if they are
    not empty, the files are still left in the spool directory, you can
    remove them by hand.  This command, and deleting spool files,
    should only be used with extreme caution.
2.6g
    + Made the fts-xmit process work much faster with
    binary articles.
2.6f
    + Fixed bug in drobot which was loosing the last 2 lines of messages.
    + Added tellnews command      tellnews reload_fts to re-read the fts
    database.
    + Fixed bug in processing feeds which caused xmit to miss an
      occasional article
    + (NT) Increased connection queue length and process it faster to
    deal with connection refused messages.
    + Added config setting,  expire_delay 0,  this can be used to tune the
    speed the expire runs at.  The default is 0, you might try 1 or 2 to
    make the expire impact less.
2.6e
    + Fixed bug in FTS database.
    + Fixed stats_in display for multiple feeds from the same machine.
    + Fixed getold so it will not set upto values negative.
2.6d (28-Aug-1996)
    + Fixed problem with expire taking way too long on heavily loaded
    servers.
    Note: the stats_in figure is not accurate if you have more than
    one simultaneous incoming feed from the same site.
2.6c (27-Aug-1996)
    + Fixed bug in streaming suck option.
2.6b (26-Aug-1996)
    + Added streaming option to sucking feed, to enable it add to dnews.conf
        suck_stream true
    This can triple the sucking speed or better on some systems.
2.6a (Beta release, 25-Aug-96)
    Summary of major new featres since 2.5i
        Full Text Searching added
        DNEWSWEB now automatically finds and shows images in messages
        DNEWSWEB improved to allow all the screens to be tailored.
        Expire on large systems (4Gig and up) is much faster.
        Performance improved and cpu use reduced.
        Misc bugs fixed.
    + Implemented automatic inline decoding of MIME and UUENCODED
    pictures in DNEWSWEB
    + Added 'related items' button to DNEWSWEB
    + Added header and footer files to DNEWSWEB  see dnewsweb.txt for details
    + Added 'sort by subject' option to dnewsweb.ini
    + Added Full Text Searching option to DNEWSWEB, this allows a user to
    search your entire spool disk (3 gig's) in less than a second.
    (See notes above on enabling the full text searching engine)
    + Made tellnews key command friendlier.
    + Added nntp extension XDSEARCH for Full Text Searching
    + Added nntp extension XDFIND for header searching within a group
    + Fixed bug in xmit - mailing list gateway with some mail servers.
    + Added option to dnews.conf  "nocontrol true" which stops the automatic
    creation of the newsgroups control and control.cancel
    + Improved speed of listgroup command by factor of about 10-20.
    (this can significantly improve free agent response)
    + Added pc's ip name/number to path if it is empty in posting feed
    + Fixed expire bug, if 'purge' was not defined it defaulted to 0
2.5l (20-August-1996)
    + Changed log file names from  dnews.log2 to dnews2.log, dnews3.log.
    + Added expire_small setting to dnews.conf, and made it auto config
    to 20*disk_space, (this is used when more than 90% of your disk
    is full) Made expire_chunk auto configure better too.
      These settings are not dynamic, you must restart dnews if you change
      them.
2.5k
    + Added more regular writing of active file with ihave feeds.
    + Fixed error in dnews generated line count
    + Modified select call to deal with bug in NT Sockets which
    caused 'connection refused' errors during expire runs.
2.5j
    + Patched bugs in NetWare version (with long file names)
    + Replace badly implemented system library calls strchr()
    and strstr() with our own versions which are 100 times faster in
    some cases, this gives about a 5%-10% increase in performance
    on NT.  (this also fixes the problem with 800K local posts locking up
    DNEWS for short periods)
    + Added tellnews showqueue which will show the entire sucking queue.
2.5i
    + Fixed file handle leak on unix versions.
2.5h
    + Added cached life to showcached output.
    + Added time stamp to last sucking error in status.
    + Added AUTH_CASE TRUE, which allows case sensitive user/passwords in
    access.conf
    + Minor changes for OS/2 version.
    + Fixed error in active.names processing which allowed duplicates.
    + Added tellnews command FIXNAMES which removes historical duplicates
    + Max_groups increased to 35000 on Windows NT (from 30000)
    (really there aren't this many groups, you should put something
    more restrictive in your 'me' feed and delete some of the rubbish
    from active.dat)
    + Made output from 'key' command easier to
    + Changed some sockets to non blocking, added dnews.conf nntp_block true
    to restore previous operation in event of any problems.
    + Found bug causing crash after socket closed error.
2.5g
    + Fixed EAGAIN error's (on solaris and osf) so it will wait 1 second
    before re-trying.
    + Fixed intermittent crash at end of expire on NT related
    to error messages like: "(socket_write error.."
2.5f
    + ADded option to dnews.conf:  no_newnews true, which will disable the
    newnews command.  You may want to do this to stop bad software
    clogging your network with stupid requests. (The newnews command
    can essentiall request your history file, all 100MB of it)
2.5e
    + Added dnews.conf option
        expire_bits true
    If you are running a very big system this can smooth out performance
    during expire runs.
2.5d
    + Patched 2 more socket_write errors for NT.
    + Added reporting of pc's name when license key fails.
    + Changed killitem to accept message id's
    + Fixed bug with rubbish appearing at bottom of downloading message.
2.5c
    + Increased max length of confirm settings
    + Patch for occasional crash at end of expire run on NT
2.5b
    + DNEWSWEB, fixed bug in html code so it works with netscape 2.x
    + Fixed BSDI crash
    + Added rlimit memory code for BSDI
    + Made system reject users nicely when close to 300 users connect.
2.5a
    + Added DLIST nntp extension
    + Added DNEWSWEB, a cgi program to gateway web pages into your
    news system for both local and non local groups.  See dnewsweb.txt
    for instructions on installation.
    + Fixed channel close on write causing signal on
    BSDI.
2.4q
    + New groups would sometimes not show a downloading message until
    dnews was restarted, this is fixed.
    + More minor changes for MAC version.
        + Improved 'newnews' and 'newgroups' commands to minimize impact and mem used.
    + 'newgroups' now obeys 'access.conf' settings so users don't see 'new' groups
    that they cannot actually read.
    + Fix for outgoing feeds to ports other than 119
    + Fixed control panel start/stop of xmit service.
    + Reduced memory use for xmit.
2.4p
    + Improved memory handling some more, changed string allocation
    method to avoid block fragmentation and free more strings if
    a channel closes.
    + Reduced over allocation for group data.
    + Fixed bug with SUNOS strstr() routine, result is DNEWS runs
    about 5 times faster on SUNOS than it used to.
2.4o
    + Added dnews.conf parameter SUCK_TIMEOUT default is 300, only used
    when sucking an article and the line is inactive for this period then
    the channel is closed.  (Default was 180 seconds in previous versions)
2.4n
    + Another memory leak fix, also fixes a bug with xmit which would
    have existed since 2.4f
2.4m (I don't like the letter l)
    + Fixed bug with article corruption (usually only occured with
    large articles on tcp links that go up and down alot)
    + Header cache is cleared after expire, (stops misleading xhdr output)
    + Minor code changes for MAC version
2.4k (Beta)
    + Fixed dnewsmanager which was writing large dnews.conf files.  You
      should start dnewsman and click on the 'write' button to
      allow the dnews.conf file to be corrected.  (this may save some memory)
    + Fixed unix crash (only some flavours) if connections closed
      while sending to them. (introduced in 2.4f or maybe 2.4g I think)
    + Fixed problem with newly added groups not showing 'downloading' message
    + Fixed crash if list of feed groups is more than 500 char long and
      status command is run.
    + added total bytes to stats_in output
2.4j (Beta 19/June/1996)
    + Fixed processing loop after connections close.
2.4i (Beta 18/June/1996)
    + Fixed bug with large cross posted items introduced in 2.4g
2.4h (Beta 17/June/1996)
    + Fixed memory problem if active.times file gets too large.
    + Fixed bug with multiple sucking which would have caused dnews to
    re-check items from secondary sucking sites.
2.4g (Beta 16/June/1996)
    + Made date of fake article 60 days old to ensure the article does not
    get sent to other news servers successfully.
    + Fixed Expire Report crash if less than 40 groups existed.
    + Fixed bug in date parsing, there was a bug in processing some date
    formats. This could have caused some valid articles to have been rejected.
    + Prevented memory build up from the following commands:
        xover,xhdr,list,article,body
    + Made default list output only show groups that the user can read.
    + Added tellnews command "update_clear" to empty the update queue.
    + Fixed crash if active.names file was larger than memory.
2.4f (Beta 6/June/1996)
    + xmit, log file now rotated every 10,000 lines.
    + Fixed memory usage bug, with some news readers dnews was
    allowing more requests than the news reader (or modem link) could
    handle, this caused a large build up of RAM.
    + Fixed 2.4e bug with updates only occuring once per hour instead
    of every 10 minutes.
2.4e (5/June/1996)
    + Increased max connections on Solaris to 300, linux to 200
      (same applies to other rlimit based unix systems)
    + Enhanced caching logic so it will now deal with a machine
      slurping news by message ID and not get confused about which
      'groups' are being read due to cross posting confusion.
    + cachedonly true also works better
    + Added tellnews commands
        tellnews update2,3,4  To update from alternate sucks.
        tellnews updateone rec.humor.* 3    To update one or a few groups from suck3
        tellnews showcached [rec.*]    To show all cached news groups.
    + Expire, timing logic changed so it is 'hourly' based, this ensures
      it is not missed occasionally.
    + Added option
         expire_fast true
      This makes the expire process run at a high priority, the DEFAULT
      is now LOW priority, so it doesn't interfere with people
      reading news
    + Added dnews.conf option
             hide_queue true
         This hides the names of the entries in the sucking queue, so little
      old ladies are not offended by naughty group names.
    + Added dnews.conf setting
         suck_requeue true
      This tells it to requeue any groups which are not finished due to the
      batchn, or batchsize settings.
    + Added dnews.conf setting
        groups_at 44 1
      Triggers a fetch for any new group names from the feeder site once
      per day (1:44 a.m.).   This will be the default for new
      installations, for old installations you may want to add this line.
    + Made 'getgroups' run as a background task so it doesn't impact on
      performance.
        + Made xover and xhdr run without blocking other nntp sessions, and
      smoothed out response.
    + Added xover cache, default size is 3000 (which will use about 600k)
      If you have 32MB I would suggest increasing this to about 10000
      If you have More than 32MB, try about 20000
      In dnews.conf add:
          xover_cache 10000
      At the same time you may want to reduce HEAD_CACHE to about 200 if
      your are short of memory as the xover cache is much more efficient
      and uses less memory.
    + Added tellnews commands
            tellnews getgroups 2
      Which will get new groups from 'suck2' automatically.
      (usually run this once when adding a second sucking feed like
       the microsoft news groups, warning, it will add all groups
       that the other server offers, ignoring the 'suck2' group
       wildcard. (but it does obey the 'me' wild card in newsfeeds.conf))
    + Fixed bug with multiple reports being sent each night.
2.4d (19-5-96)
    + Fixed crashing bug for sites not doing any sucking (introduced
    in version 2.4a)
2.4c
    + Fixed bug in sucking different groups from multiple sites
2.4b
    + Digital Unix bug fix in history memory allocation
    + Changed default for nntp_slow to FALSE
    + Added code to correct item start count for a group in the event of
    files dissappearing.
    + Made outgoing posting feed work with more than one posting feed, each local
    post is checked to see which 'posting' feed it should go to.
    (by matching the 'groups' in newsfeeds.conf)
2.4a
    + Multiple sucking feeds modified, you can now suck one group from
    several sites.  You MUST change your config file if you are
    sucking from more than one site!!!
    + active.dat file now has 3 extra values, (the end points for the
    additional sucking feeds)
        + The UPDATE_GROUPS1,2,3 dnews.conf parameter is now obsolete.
        + Here is an example setup for taking alt groups from two sites and
        microsoft groups as well.

        nntp_feeder main.feeder.site *,!microsoft.*
        nntp_suck2 alternate.feeder !*,alt.*,!microsoft.*
        nntp_suck3 msnews.microsoft.com microsoft.*

        update_at *5 *        #  Get  main groups every 10 minutes
        update_at2 20 3       # Get missing articles once a day
        update_at3 40 9,12   # Get Micrsoft articles at 9:40 and 12:40

    In newsfeeds.conf you would have
               site me
                  groups *
        site $nntp_feeder
            groups *,!microsoft.*
            builtin
            posting
        site msnews.microsoft.com
            groups !*,microsoft.*
            builtin
            posting
        ...

    Please don't update every 10 minutes from microsoft, as they could
    easily get over loaded :-)

    + Minor change to processing of LIST command which should improve
    speed if there are lots of deleted groups.

2.3p
    + Fixed behaviour of built in feed for 'duplicate' errors, BUT, this
    is generally a sign that your EXCLUDE parameter is wrong and should
    be fixed.
    + Added dnews.conf setting 'replicate true' which tells dnews to
    use the same item numbers as the host it is fetching items from, you
    should NEVER set this parameter on an already running system, it's purpose
    is for setting up MIRROR news servers.
    Both of these settings should be used together:
             replicate true
         postonly true
    And your feed on each of the mirror news servers should be defined as
            site $NNTP_FEEDER
             groups *
             builtin
             posting

2.3o (12/5/96)
    + Fixed bug with sucking from multiple sites, it was intermittently
    sucking groups from the wrong site.
    + Added MAX_SPEED setting, this limits the speed of incoming
    connections in bytes/second.  Useful to smooth out peformance
    and limit the impact on a wide area line: Here's a typical setting.
           max_speed 10000
    + Added CANCEL_ANYONE true,  enables all cancel messages even
    if they are not from the original poster
    + Added CANCEL_USERS me@here, only allows cancel messages from you.
    + Added LIST_READONLY true to dnews.conf, this stops dnews from
    reporting groups to a user if the user is not able to read them.
    (due to access.conf settings)
    + Added config parameters
        SUCK_BATCHN 100
        SUCK_BATCHSIZE 3000000
    These limit the number and total size of
    items to suck from one group at one go.
    + Fixed config processing which could cause
    errors with blank parameters.
    + Made rmgroup/killgroup work for mixed case groups.
    + Added 'n groups deleted' to output from rmgroup/killgroup
    + Modified buffering of output to improve compatibility with faulty
    news reader software.
2.3n (5/5/96)
    + Increased connection limit on NT from 128 to 300
2.3m (3/5/96)
    + Added config SEND_AT and SEND_LATER
        SEND_AT *5 *        Sends mail and builtin feeds every 10 minutes
        SEND_LATER TRUE     Stops dnews from trying to send immediately a post is sent
    + Fixed netscape/freeagent (old version)/dnews bug where messages
    posted with bad headers gave 'no such newsgroup' errors when the
    user tried to read them.
    + Fixed bug with dposter processing large messages, where dposter
    would somtimes lock up. (probably only on NT)
    + Fixed scroll bars on Dnews Manager status windows (yay!)
    + Registration codes changed, this should not affect any registered
    users, however, if you have a problem please contact [e-mail]
    and we will provide you with a new registration key.
2.3l (19/4/96)
    + Fixes bug with cancel processing
    + Fixed bug with Netscape access using usernames and passwords
        It is important to have access.conf lines in the correct order
        the following example which used to work will no longer work:

               *:logoff:::*
               *.my.domain:read,post:::*
               *:read,post:joe:joepassword:*

         This is because the username line will be matched in anticipation
         of the user/password info being sent.  So these lines should
         now appear ABOVE wildcard matching lines, e.g.:

               *:logoff:::*
               *:read,post:joe:joepassword:*
               *.my.domain:read,post:::*

        So the logic is now: If he is in MY domain, he can read
        and post, but if he isn't in MY DOMAIN then he can connect
        but cannot do anything until I see a user/password combination.

2.3k
    + Fixed bug with not sending AUTHINFO when posting upstream.
2.3j
    + Fixed occasional crash if sucking connection closes unexpectedly
    + Fixed crash if control message tries to create illegal group name.
    + Corrected format of MAIL TO: messages for confirmations and added Message-ID
2.3i
    + The MOSAIC 2.0 news reader contains a bug, if you MUST use this
    news reader then in dnews.conf set:
              nntp_slow true
          chan_nobuff true
    Then it should work most of the time until Mosaic fix the bug :-)
    (this may not work if you use XMIT, I haven't tested it :-)
    + Fixed bug in xmit if destination site resonded with <msgid>xxx
      with no 'space' after the right angle bracket.
    + Fixed bug with Microsoft Internet Explorer 2.x and Downloading message.
    + Fixed bug with fast history file, so it now works faster
    + Added stats commands
           tellnews stats_in      Shows stats in incoming feeds
           tellnews stats_groups  Shows stats on group usage/size
2.3h
    + Expire crash bug fixed (thanks to Karsten Thygesen)
    + Added '&' as a valid newsgroup character, e.g. calvin&hobbes
      However, I can't find any newsreader which will work with an '&'
      in a group name so I have my doubts about it.
2.3g
    + Fixed error message bug  (no such file...) repeating in log file.
    + Fixed caching detection for news readers that read items by
    message ID (e.g. netscape 1.x)
    + Fixed bug in xmit causing PANIC errors and crashes. (I think :-)
2.3f
    + Compile warnings fixed, thanks to Karsten Thygesen
    + Speeded up history file access by adding match code. (this will
    help large sites taking full feeds)
    + Support for UUCP now provided, see the sections above titled:
        Setting up a UUCP feed out of DNEWS
        Setting up a UUCP feed into DNEWS
    + 201, posting not allowed, now accepted by xmit as a valid return code.
    + Fixed NT crash when socket closed with unusual error message. (again)
2.3e (21/Feb/96)
    + On Windows 95 start and stop buttons now work from DNEWS Manager
    + History lookup in cache (so new posts can always be found)
    + Group cached life is not decreased when it is read, only increased.
    + Cancel messages from Freeagent are now obeyed despite their dubious format.
    + Added 'logoff' setting for access.conf, use this to deny access.
    + Added caching for DNS lookups and reverse lookups.
    + Added dnews.conf  NNTP_LOGOFF setting which will be sent to connections
    which do not gain access thru access.conf. The default string is:
          nntp_logoff You have no permission to talk
    + InstallShield now checks for 3mb of space on
        %temp% disk, system disk and spool disk.
    + Fixed NT crash when socket closed with unusual error message
2.3d (11/Feb/96)
    + Default feed fixed for builtin feeds which aren't sucks.
    + Increased line length for access.conf and expire.conf
    + Changed several strcpy's to ncpy's
    + If history fails to open it will retry
2.3c (7/Feb/96)
    + Oops, bug introduced in 2.2g which caused crash during startup
    if nntp_feeder was not defined.
    + InstallShield now used for installations (thanks to Danny Mayer)
    + DNEWS Manager GUI released (beta)
2.3b
        + Fixed bug with long headers being messed up from some news servers
2.3a
        + Released
2.2g
    + Added to dnews.conf, for updating some groups at more frequent times
              update_groups1,2,3  interesting.groups.* *5 *
    + For sucking groups from other news servers.
          nntp_suck2,3,4 site.name local.* [username password]
2.2f (30/1/96)
    + Cleaned up nntp error message.
    + Fix access.conf problem with read and post mix up.
2.2e
    + Fixed bug in database which caused idx files to become corrupt on
      occasion.
    + Made open's non blocking, you can reverse this using OPEN_BLOCK TRUE
      in dnews.conf
2.2d (20-Jan-1996)
      + Put exit handler back into unix version. (removed during debugging)
2.2c (19-Jan-1996)
    + Improved handling of corrupt database files which could cause crahes
    in some circumstances.
2.2a (15-Jan-1996)
     + Made log files rotate every 100,000 lines by default (debug_rotate 100000)
    + Made expire higher priority than sucking news items.

2.1v (13-Jan-1996)
     + Fixed key problem for MIPS-NT
    + Fixed database problem with corrupt files causing problems, added
    config parameter UPGRADE TRUE which you should set if you are upgrading
    from dnews version 1.x to 2.x
2.1u (12-Jan-1996)
    + Added tellnews undelete wildcard,  this command will mark deleted groups
    as normal again.
    + The ME feed rule is not obeyed for crossposts if you have coppied an
    active file from another machine, you need to type in:
             tellnews matchfeed
    to prevent cross posts from appearing in groups that are not in your
    me feed.  If you change the 'me' feed and want to 'add in' groups which
    were previously deleted you may need to do something like
              tellnews undeleted *binary*
          tellnews matchfeed
    + Fixed bug involving file handles.
    + Fixed problem with entering license key on expired systems
2.1t (5-Jan-1996)
        + Fixed minor bug in vms version, crashed if group names exceeded 80 chars
    + Added command:  tellnews group_merge,  this adds any groups in a file
    called active.add to the active.dat file.  Use this to merge in new groups
    from another server.
2.1s (3-Jan-1996)
    + Fixed bug with posting multi part items with 'posting' feed.
    (actually the return status was being sent twice which was confusing
    the news readers)
2.1r
    + Fixed bug with ihave feed of items larger than 1MB causing 10 minute
    delay in feed.
2.1q
    + Fixed crash if .itm file is badly corrupt. (added speed stats)
2.1p
    + Fixed status code for failed items when recieving a streaming feed.
2.1o
    + Fixed two expire bugs, one if the history file contains only one line
    then dnews crashed, another if every single line was expired, then
    dnews crashed.
    + email confirm now allows a list of email domains, e.g.
              confirm  *.newyork.com,*.la.com

2.1m (3/12/95)

2.1k
    + added NNTP_SLOW TRUE option to dnews.conf, this stops dnews from
    sending to a socket unless it is ready for more.  Shouldn't have
    any effect, but... :-)   (don't use this, it was just for debugging)
    + Added NOSTREAM true option to dnews.conf,  this disables incoming
    streaming
    + Changed priority of feeds so posts will go out sooner.
2.1j
    + Fixed one possible file handle leak
    + Added -mail option to xmit, this allows news groups to be sent to
    mailing lists, the other half (mailing lists to news groups) will be
    implemented shortly,  see the faq section above on setting this up.

2.1i (20/11/95)
    + Fixed bug, item far too big error keeps repeating after first failure.
2.1h
    + Modified db_hash which could return a negative number
    + Made suck and feeds timeout after 5 mins if other ends stops responding.
    + Fixed minor bug with internal feed which could cause a crash
    + Fixed return code if connection is refused
    + Fixed xmit bug
    + Fixed bug if access is refused and connection is terminated by other end.
2.1g
    + Added config parameter NNTP_BIGREJECT, the default value is 439, you
    might need to set this to 437 for some incoming feeds. (but very unlikely)
    (the default will now work with innxmit which is buggy and collapses
    if you give it the correct response code)
     + Added uptime to status
    + Fixed bugs which could cause crashes if an item index file was corrupt.
    + Added NT translation of filename 'nul' which is not valid on NT.
    + Fixed bug on Solaris systems with dnews not responding under some
    conditions. (it would appear to be locked up but still be running fine)
2.1f (internal release mainly)
    + Improved logging of file open/close
2.1e (4/11/1995)
    + Fixed lib_strdate, which was producing bad time stamps
    + Fixed posting problem with INN servers
    + Fixed 100% cpu use caused by connections closing after asking for more
    than 100K of information.  (e.g. list followed by quit)
2.1d (4/11/1995)
    + Fixed addlost bug
2.1c (2/11/1995)
    + Changes to memory allocation for NT.
     + Now deals with & in news group names on NT.
2.1b (1/11/1995)
    + Fixed crash if NULL item is sent (should never happen anyway but
    some news feeders do it rarely)
2.1a (31/10/1995)
        + Full release of version 2.x
2.0 Beta-5
    + Added dnews.conf paramter, open_retry, it defaults to 60 minutes.
    This is how long dnews should wait before re-trying to open a channel
    to your feeder site if it fails the first time.
        + upgrade command changed to 'doupgrade' to avoid confusion with 'update'
    command.  So when you upgrade from any version 1.x copy of dnews to 2.x
    you should enter:   TELLNEWS DOUPGRADE
    You DO NOT need to do this with every upgrade, it is only needed once
    when you go from 1.x to 2.x
    + Fixed new feature so it doesn't get a whole list of groups unless
    you have more than 300 cached (feature was supposed to work in beta-2)
2.0 Beta-4
    + Fixed expire so that if it is above 94% when it starts it will recheck
    the free disk space after deleting the first 10,000 items.
    + Fixed nntp command list newsgroups.
    + Modified memory allocation again :-)
2.0 Beta-3  (26-Oct-1995)
     + Fixed bug in xover introduced in Beta-2
2.0 Beta-2  (24-Oct-1995)
    + dnews.conf item_max defines how large an item dnews can process, if an
    item larger than this is recieved it will be rejected.  Increasing this
    can waste memory.  The default is 1000000 (1mb)
    Note: in newsfeeds.conf there is also a setting for rejecting large items
    per feed rather than globally.
    + String allocation routines re-written to allow memory compaction on
    the fly, also minor changes to indenting style to solve all other
    memory problems.
    + Update made more intelligent so it doesn't get a list of newsgroups
    every 10 minutes unless you have more than 300 news groups cached.
    + New command,  tellnews getgroups, which will force an update of group
    names which won't happen automatically if you are using less than 300
    cached groups :-)

2.0 Beta-1  (22-Oct-1995)
        NOTE:  After installing type in:
             tellnews upgrade   (now DOUPGRADE instead)
          + New database Format, note the database will be upgraded 'on the fly'
    however, it is recommended you do a TELLNEWS UPGRADE to make sure
    the entire database is upgraded, and performance will not be good
    while this is happenning, so try and schedule it for off-peak time.
    + File IO improved to handle much heavier loads and improve
    xover performance when groups are heavily cross posted.
    + The following NNTP commands all speeded up by about a
    factor of 10,  NEWNEWS, NEWGROUPS, GROUP.
    + History rebuild fixed (tellnews addlost)
    + XMIT exiting when it can't connect fixed.
    + Log files flushed more completely
    + Timeout of idle channels now settable in minutes (TIMEOUT NN)
     in dnews.conf
    + Two new settings to clearly specify how cached
     groups should be dealt with:
      cachedonly true  (don't allow items into non cached groups)
      cachedall true   (pretend all groups are cached)
    The first one can be used to emulate a sucking feed when
     items are being sent in with IHAVE.
    The second one is for FULL feeds to prevent any 'downloading'
    messages appearing.
    + Case is now preserved in group names, I don't like mixed case
    group names but they exist so DNEWS will now deal with them,
    however, it's matching is non case sensitive, (like NT file names).
    + New command TELLNEWS FIXRANGE which rechecks the
    number of items in each group.  (this doesn't expand the range of numbers
    use addlost to do that)
    + Modified memory allocation routines to avoid common operating system
    bugs, resulting in much lower memory use.
    + Fixed bug with running out of file handles if the feed site isn't
    responding.
    + Changed log files.  There are now three,  dnews.log (all log messages)
    dnews.in (Log of incoming articles) dnews.out (log of outgoing articles
    and email)  The loglvl affects what gets stored in dnews.log
    debug_rotate can be set to prevent log files from getting too big.
    + TELLNEWS ROTATE command added to rotate log files.
    This also happens once per night automatically.  Files are renamed:
          dnews.log -> .log2 -> .log3 -> .log4 -> (deleted)
    + New dnews.conf setting,  ACTIVE_STATIC TRUE, will stop new groups from
    being created by the sucking feed.  (good if you don't want 20,000
    empty news groups slowing things down.
    + Newnews command fixed, it was not responding with the correct status.
    + Config parameter.  POSTONLY TRUE,  which stops items from being posted
    locally until they come 'back' from the feeder.  (this is the way it
    used to work until version 2.0)  The advantage of the new default is that
    you can have local groups and they will work even with a posting feed.
    + If WinVN crashes every time you try and read a newsgroup then type in.
        tellnews fixrange
       WinVN gets upset if DNEWS reports an incorrect number of items in a
    group and DNEWS can get this number wrong in rare circumstances usually
    just after upgrading.
    + Maximum number of newsgroups increased from 20,000 to 35,000.
    Note: Just because DNEWS can handle it, doesn't mean the pc news readers
    can, if you look in one of these large active files you will find an
    awful lot of crap, I suggest you save memory and bandwidth by removing this
    rubbish.

1.1g (30-Sep-1995)
    + New mailing list for discussion, send to  [e-mail]
     + Added config setting NODNS this will stop dnews from doing reverse
      name translations.  If you find your system takes 30 seconds to connect then
      try this setting, it could be your reverse name translation server
      is not working.  This only affects access.conf, you will have to
      put 'numbers' in to control access instead of names.
     + Fixed bug in expire and purgelost.
    + Added 'TELLNEWS ADDLOST' command, this will restore the history file if
      it is deleted.  (You don't need to delete it first unless it is corrupt)
     + *** Upgrade procedure,
      I recommend after upgrading to 1.1g you type in:
          tellnews purgelost
      On a system with many gigs of news this may take 24hours to run.
      (the system will be very slow while this is running)
      Then use the command:
            tellnews setused nnn
      To set the current disk usage correctly (nnn=MB used)
1.1f (27-Sep-1995)
    + Fixed bug with header records containing tabs being returned by
    xover or xhdr incorrectly.
1.1e (26-Sep-1995)
    + Fixed bug in body command, if body is empty the server crashed.
    (although this is rare as empty body messages are not accepted
    it can only happen when the database is corrupt)
    + Fixed free disk space display on NT
    + Added reporting on memory allocated
    + Added LOGDIR_MIN to config files
    + Added TELLNEWS STATS command.
    + Fixed History memory usage display
    + Fixed 'mode reader' command, it had a trailing space and some
      news servers didn't like that. (thanks to S White for finding this)
    + Fixed bug with the 'cached' groups, they were not
      being 'reset' as cached when users read items.  (bug introduced a couple
      of version back)
1.1d (20-Sep-1995)
    + Fixed expire problem (with deleted groups)
    + Removed code that prevents ihave incoming when outgoing feed is
    posting (but this is still probably a bad idea)
    + Fixed memory leak in NT version.
1.1c (14-Sep-1995)
    + Fixed remaining memory leaks.
    + Changes default FEED_READER to TRUE.
1.1b (Internal only)
    + Fixed tellnews command when port is not 119
    + Fixed bug when expring if no items in system at all.
    + Added FEED_READER TRUE OR FALSE, to force the 'mode reader' command
        to be sent, or not sent.
    + Added maxcross flag for limiting crossposts in newsfeeds.conf
    + Made major improvements in memory allocation, greatly reducing
      memory usage.
    + Added debugging option    DNEWS_ROTATE 1000
    + Fixed bug if the right/wrong slash is used in dnews.conf on NT
1.1a (6-Sep-1995)
    + Fixed possible bug with very long group names.
1.0e (Internal version)
    + Fixed possible bug with multiple simultaneous incoming ihave feeds
    + Fixed possible bug with items cross posted to > 200 groups
    + Fixed possible bug with incoming items corrupting memmory.
    + Fixed bug with tellnews.pass not being accessible after it runs
      out of disk space.
    + Extended newsfeeds exclude command to allow a list of sites
      e.g.  exclude feeder1.site,feeder2.site
1.0d (Internal version)
    + Fixed NNTP DATE command, required by TRN
    + Fixed NNTP responses for list commands for TIN
    + Added dnews.conf paramter PORT to run the server on a different port.
    + Added dnews.conf NNTP_USER, NNTP_PASS user and password for feed site
    + Fixed bug internal mail sending system (NT & VMS not saying HELO)
    + Added NNTP extension      list active x.y.z
    + Added config,  LOGUSE ON, enables reader logging to used.log
    + Added config, CACHEDONLY ON, stops messages from going into groups
      that are not cached.  Use this to make an ihave feed become partly
      dynamic.
1.0c (22-Aug-1995)
    + Made feed and mail queues higher priority than background suck entries.
    + Fixed major bug in internal feeding code which could loose local
      posts if the system was under load when it tried to send them.
    + Fixed possible crash during expire if history file was corrupt.
1.0b (20-Aug-1995)
    + Fixed tellnews reload so it reloads dnews.conf, access.conf
      and newsfeeds.conf.  Also made expire.conf reload automatically.
