++ *
++ * For Farm9:
++ * ---  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
++ *      (or with extreme caution).

++ *      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
++ *      (or with extreme caution).

++/*
++ * 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.

++# snortsam
++# In order to cause Snort to send a blocking request to the SnortSam agent,
++# that agent has to be listed, including the port it listens on,
++# and the encryption key it is using. The statement for that is:
++#
++# output alert_fwsam: {SnortSam Station}:{port}/{password}
++#
++#  {SnortSam Station}: IP address or host name of the host where SnortSam is running.
++#  {port}:             The port the remote SnortSam agent listens on.
++#  {password}:         The password, or key, used for encryption of the
++#                      communication to the remote agent.
++#
++# At the very least, the IP address or host name of the host running SnortSam
++# needs to be specified. If the port is omitted, it defaults to TCP port 898.
++# If the password is omitted, it defaults to a preset password.
++# (In which case it needs to be omitted on the SnortSam agent as well)
++#
++# More than one host can be specified, but has to be done on the same line.
++# Just separate them with one or more spaces.
++#
++# Examples:
++#
++# output alert_fwsam: firewall/idspassword
++# output alert_fwsam: fw1.domain.tld:898/mykey
++# output alert_fwsam: 192.168.0.1/borderfw  192.168.1.254/wanfw
