-  Snort is an open source network intrusion detection and prevention system.
-  It is capable of performing real-time traffic analysis, alerting, blocking
-  and packet logging on IP networks.  It utilizes a combination of protocol
-  analysis and pattern matching in order to detect anomalies, misuse and
-  attacks.

-+ * Purpose:
-+ *
-+ * This module sends alerts to a remote service on a host running SnortSam
-+ * (the agent) which will block the intruding IP address on a variety of
-+ * host and network firewalls.
-+ *
-+ * SnortSam also performs checks against a white-list of never-to-be-blocked IP addresses,
-+ * can override block durations (for example for known proxies), and can detect attack conditions
-+ * where too many blocks are received within a defined interval. If an attack is detected
-+ * it will unblock the last x blocks and wait for the attack to end.
-+ *
-+ * See the SnortSam documentation for more information.
-+ *
-+ *
-+ * Output Plugin Parameters:
-+ ***************************
-+ *
-+ * output alert_fwsam: <SnortSam Station>:<port>/<key>
-+ *
-+ *    <FW Mgmt Station>:      The IP address or host name of the host running SnortSam.
-+ *    <port>:                 The port the remote SnortSam service listens on (default 898).
-+ *    <key>:                  The key used for authentication (encryption really)
-+ *                            of the communication to the remote service.
-+ *
-+ * Examples:
-+ *
-+ * output alert_fwsam: snortsambox/idspassword
-+ * output alert_fwsam: fw1.domain.tld:898/mykey
-+ * output alert_fwsam: 192.168.0.1/borderfw  192.168.1.254/wanfw
-+ *
-+ *
-+ * Rule Options:
-+ ***************
-+ *
-+ * fwsam:     who[how],time;
-+ *
-+ *  who: src, source, dst, dest, destination
-+ *                    IP address to be blocked according to snort rule (some rules
-+ *                    are reversed, i.e. homenet -> any [and you want to block any]).
-+ *          src denotes IP to the left of -> and dst denotes IP to the right
-+ *
-+ *  how: Optional. In, out, src, dest, either, both, this, conn, connection
-+ *                    Tells FW-1 to block packets INcoming from host, OUTgoing to host,
-+ *                    EITHERway, or only THIS connection (IP/Service pair).
-+ *                    See 'fw sam' for more information. May be ignored by other plugins.
-+ *
-+ * time: Duration of block in seconds. (Accepts 'days', 'months', 'weeks',
-+ *             'years', 'minutes', 'seconds', 'hours'. Alternatively, a value of
-+ *             0, or the keyword PERManent, INFinite, or ALWAYS, will block the
-+ *             host permanently. Be careful with this!
-+ *                    Tells FW-1 (and others) how long to inhibit packets from the host.
-+ *
-+ * Examples:
-+ *
-+ * fwsam:  src[either],15min;
-+ *     or  dst[in], 2 days 4 hours
-+ *     or  src, 1 hour
-+ *
-+ *         (default: src[either],5min)
-+ *
-+ *
-+ * Effect:
-+ *
-+ * Alerts are sent to the remote SnortSam services on Firewall-1 Management Stations
-+ * or other hosts running SnortSam (as required for Cisco Routers and PIX).
-+ * The remote services will invoke the SAM configuration via the fw sam
-+ * command line, or by sending a packet to the SAM port 18183, or by using the official
-+ * OPSEC API calls, or by telnetting into Cisco routers or PIX firewalls.
-+ * The communication over the network is encrypted using two-fish.
-+ * (Implementation ripped from CryptCat by Farm9 with permission.)
-+ *
-+ * Future Plans:
-+ *
-+ * - Custom alert trigger per rule (x alerts in y secs) --> Seems to exist in Snort 1.9 now.
-+ * - Enable/Allow tagged fwsam: arguments to provide different values to
-+ *        different stations.  --> Seems to be accomplished with custom rule-types
-+ *
-+ *
-+ * Comments:
-+ *
-+ * It seem that above wishes can be implemented with todays setup. Feedback concerning
-+ * these is greatly appreciated.

-+ * ---  jojo@farm9.com, August 2000, converted from Java to C++, added CBC mode and
-+ *      ciphertext stealing technique, added AsciiTwofish class for easy encryption
-+ *      decryption of text strings
-+ *
-+ * Frank Knobbe <frank@knobbe.us>:
-+ * ---  April 2001, converted from C++ to C, prefixed global variables
-+ *      with TwoFish, substituted some defines, changed functions to make use of
-+ *      variables supplied in a struct, modified and added routines for modular calls.
-+ *      Cleaned up the code so that defines are used instead of fixed 16's and 32's.
-+ *      Created two general purpose crypt routines for one block and multiple block
-+ *      encryption using Joh's CBC code.
-+ *            Added crypt routines that use a header (with a magic and data length).
-+ *            (Basically a major rewrite).
-+ *
-+ *      Note: Routines labeled _TwoFish are private and should not be used

-+ * Frank Knobbe <frank@knobbe.us>:
-+ * ---  April 2001, converted from C++ to C, prefixed global variables
-+ *      with TwoFish, substituted some defines, changed functions to make use of
-+ *      variables supplied in a struct, modified and added routines for modular calls.
-+ *      Cleaned up the code so that defines are used instead of fixed 16's and 32's.
-+ *      Created two general purpose crypt routines for one block and multiple block
-+ *      encryption using Joh's CBC code.
-+ *            Added crypt routines that use a header (with a magic and data length).

-+ *
