            On behalf of the Honeynet Project, I would like to announce the
    release of snort_inline-1.9.1. This version of snort_inline has been
    updated to the latest version of Snort: 1.9.1, with a few
    modifications. You can download it at:

    http://project.honeynet.org/papers/honeynet/tools/

            snort_inline takes packets from iptables instead of libpcap. It
    then uses new rule types to help iptables make pass or drop decisions
    based on the snort rules format. These new rule types consist of:

    drop - The drop rule type will tell iptables to drop the packet and log it
    via usual snort means.

    reject - The reject rule type will tell iptables to drop the packet; log
    it via usual snort means; and send a TCP reset if the protocol is TCP or
    an icmp port unreachable if the protocol is UDP.

    sdrop - The sdrop rule type will tell iptables to drop the packet.
    Nothing is logged.

            To get you started, Mike Clark <mike@honeynet.org> has started a
    drop ruleset to stop suspicious traffic from leaving a compromised
    Honeypot. A copy of this ruleset can be found in the rules directory of
    the snort_inline-1.9.1 package, but the latest and greatest can always be
    found at:

    http://project.honeynet.org/papers/honeynet/tools/drop.rules

            Also, in order to ensure a drop rule has precedence over an alert
    or log rule, the rule application order has been changed. The
    snort_inline-1.9.1 rule application order is:

    ->activation->dynamic->drop->sdrop->reject->alert->pass->log

    Also, if you don't feel like downloading and compiling source code, take a
    look at the HONEYNET SNORT_INLINE TOOLKIT. This is a statically compiled
    snort_inline-1.9.1 binary put together by the Honeynet Project for the
    Linux Operating System. It comes with a set of drop.rules, the
    snort_inline binary, a snort-inline rotation shell script, and a good
    README. It can be found at:

    http://www.honeynet.org/papers/honeynet/tools/

            For more details on installing, configuring, developing, and
    running snort_inline-1.9.1, please read the doc/README.INLINE contained in
    the package.

            Feel free to contact me at rvmcmil@cablespeed.com if you have any
    questions, concerns, or gripes regarding snort_inline-1.9.1.
