    I use knode and setup filters. I can filter on any header field.

    don't think automagic spam detection would work with newsgroups like it
    does with email addressed specifically to you. I think it would be close to
    impractical perhaps even impossible due to the nature of usenet? I would
    like to be prove wrong though What do mailinglists do to prevent the
    spam?

    With mailinglists the messages get scanned before it's 'released' to the
    subscribers of the list.
    If you read usenet messages you most likely only download the headers of
    messages first, only when you select a message the body gets downloaded.

    So if you would like to have spam filtering like with email, you have to
    setup your newsreader so that it dowloads the headers and body's of
    messages so it could filter on contentalso and not only on headers.

    Offcourse downloading all headers and body's of messages every time you read
    a group is not what you want.

    I don't filter anything software wise, i just use my eyes.

    That depends on how you configure your newsreader. I always download
    everything. This used to be due to the fact that then I could connect,
    download, disconnect, read, answer, connect, upload, disconnect.
    If you pay per second (1.50EUR/minute was the price at one moment) you
    do not want to be connected.

    Yes and no. I use leafnode and can filter before I download. e.g. any
    crossposting to a winders group gets killed. I do not even see it.

    I use some filetering, but a better way is to look for a different
    newsserver. I do see the occasional spam, but not in those amounts that
    it gets unreadable.

    These are the servers that I use.
    root@penne : grep ^server /etc/leafnode/config|awk '{print $NF}'

    news.evonet.be▓
    fb1.euro.net╣
    news.readfreenews.net│

    ╣ Free. Only need to register
    ▓ My providers newsserver, so I pay for them indirectly. The xs4all.nl I
    can use still, beacsue at the moment I registerd in Belgium it was one
    company. New clients won't be able to get that.

    What is better about these servers?
    Do they have spamfilters running on their servers?

    Anyway, most spam is easy to spot just by looking at the subject header.

    Then most likley your newsfeed is filterd.

    1st is redundency. Exept for the last that has different groups. Is it
    needed? Not realy. The way Usenet is setup it can happen that once in a
    while you miss a posting (hence the importance of correct quoting,
    although it is not the only reason). If you have several newsservers,
    the one missing posting will most likely be caught and you can see it.

    This means that you need to be able to read those feeds simultaniously
    and not switch between servers. Ther comes leafnode. It is a very simple
    usenet server.

    leafnode fetches all the messages, turns them into one newsfeeed on my
    server. I read the news localy. Posting I do localy as well and leafnode
    posts it via the server I desire. This can even be different ones for
    different purposes. e.g. novell.* to the novell server. Binaries to
    another. Whatever I desire.

    > Do they have spamfilters running on their servers?


    Yes, or at least get their feeds from servers that do.

    > Anyway, most spam is easy to spot just by looking at the subject header.


    You mean subject or header? If subject, I suppose you mean to be able to
    spot it yourself. If header, then you could filter it out if there is a
    consistency in the spams, which is unlikely.

    Well there are several headers, one of them is the subject header wich
    contains the subject ;-)
    If I understood correctly that is..

    Well, it would have been easier to say `the subject-header` or `the
    header "subject"` or just `the subject`. Adding `header` only confuses
    and is a bit of reduntant, as it is obvious that it is in the header.
    But hey, I don't want to be anal about it. :-D

    I've used Pan for so long now and I hate this version (and hated it when
    I've run across it on other distros also). I want version 0.14.2.91 which
    I can't get to install. I can't even find filters and rules in this new
    one and that is a must have.

    With mandrivia I was able to get it to install on 2007.1 by using a
    rpm built for 2007.

    Tried to compile the older version from source but it would appear I
    will have to do something drastic to get it working.

    I haven't tried to use an old Suse rpm, yet.

    Any other ideas?

    I actualy gave it some thought on how to call the subject-header :s

    User-Agent: Pan/0.14.2.91 (As She Crawled Across the Table)

    Possibly you want another version not the one you are using.

    >>> is there a newsreader that has a good working spam filter?


    From the FAQ that is posted to a number of Linux newsgroups twice a
    week ("Subject: A new reader? Welcome to $NEWSGROUP, read this first if
    you're new here (FAQ)"):

    "How to make killfiles for use with various newsreaders."
    http://www.hyphenologist.co.uk/killfile/killfilefaq.htm

    Most web browsers used to read news have little or no filtering
    capability, which makes a good reason to use a proper news reader
    rather than some toy.

    Some news _servers_ filter out the obvious trash. But after that, it is
    your call of how you set up filters, such as subjects, posters, even
    whole domains, or similar that you don't want to see. One fairly common
    suggestion is to filter cross-posts to off-topic, or objectionable
    groups. An example is to kill any posts that are also posted to any
    newsgroup with the word "advocacy" in the name.

    Not entirely true. The "headers" get downloaded, but they only contain
    certain fields: "Subject:", "From:", "Date:", "Message-ID:",
    "References:", "Bytes:" (rarely used), "Lines:" (not mandatory, and may
    not be set), and a message number supplied by _your_ news-server
    ("Xref:"). You can filter _directly_ on those. Other headers (there are
    a number, such as User-Agent:, MIME-Version:, Organization: and so on)
    _MAY_ be used for filtering, but the news client has to ask the server
    for that specific header, which takes additional time when on-line. Not
    all news clients support that mode, so it's best to try to get by with
    the eight default fields. Those clients that don't support the specific
    header option may either not filter on extra headers, or may need to
    download the entire article before filtering on them.

    [compton ~]$ grep -vE '^([%\[ ]|Score|$)' /var/spool/news/score | cut

    You have to look at the headers of posts you don't think are worth
    seeing. Some things are obvious, some not. Don't like posters from
    google? The obvious header would be "User-Agent:" but that's
    "expensive" scoring. A better one is to kill on the "Message-ID:".
    It does help if you (and your news client) understand "regular
    expressions" and "wild cards".

    I think just not worth the effort to figure out how to filter spam.

    Sure.
    1) Take the files (binaries and configureation) and put them manualy
    on your openSUSE box.
    2) You told you already used an RPM, so use that RPM and install it on
    your openSUSE box
    3) Use slrn
    4) Ask sdrahn to update his version (You know who he is, rigt?)

    I just add them to my filter when I see them in two newsgroups. That

    Here is mine:
    root@penne : awk -F: '{print $1}' /etc/leafnode/filters| \
    grep -v "#"|sort|uniq -c|sort -nr
    17 ^Newsgroups

    3 ^Subject
    1 ^References
    1 ^Organization
    1 ^Message-ID
    1 X-Comments


    I think I am goig to make a script `Sort` that just contains `sort|uniq
    -c|sort -nr`, because I use it a lot, or is there a better way to do
    that?

    Ah that worked, with a bit of tweaking. Sure am glad as I HATE that other
    version. I imported my color scheme also (need to do same for kate). I'd
    rather use a Suse RPM or build from source as sometimes that cause a lot
    of core dumps to get scattered about but I also have a script to search
    them out and remove them (necessary for Mandrivia as it's such a wreck).

    Now one last problem that truly does not make sense. My UT2004 loads,
    starts to connect to server and the minute it does it dies.

    My google search revealed some people having problems but the only ones
    that appeared to be my specific were written in some sort of foreign
    language like German and I sure can't read that.
