 SNF Command Line & SNFMulti Engine / Client Change Log
 ------------------------------------------------------------------------------

 20080710 - Version 3.0.1

 Minor change to SNFServer main.cpp:59 - removed cast to (int) which caused
 a precision loss error when compiling on 64 bit systems. This changes the
 thread pointer info in debug mode slightly (better).

 20080626 - Version 3.0, It's official.

 Changed build information.
 Removed extraneous comments from configuration file.

 20080524 - Version V2-9rc2.25.7

 Optimized networking library for additional speed & stability by moving
 receive buffer allocation from heap to stack (automatic).

 Optimized timing parameters in SNFClient for improved speed. Polling dealys
 are now reduced to 10ms from 30ms.

 Removed speed-bug in SNFClient, 100ms guard time between retries was always
 executed after an attempt (even a successful attempt). The guard time is now
 condition and only fires on unsuccessful attempts.

 Updated XCI server logic to ensure non-blocking sockets for clients in all
 socket implementations.

 20080424 - Version V2-9rc2.24.6

 Refactored snfScanData.clear() to reduce heap work and fragments.

 Added mutex to scanMessageFile() entry point just in case some app attempts to
 put multiple threads through a single engine handler. scanMessage() is already
 protected and fully wraped by the new scanMessageFile() mutex.

 Added non-specific runtime exception handling to XHDR injection code.

 Added 2 retries w/ 300ms delay to remove original message in XHDR inject code.
 If remove fails after 3 attempts the injector throws.

 Added 2 retries w/ 300ms delay to rename temp file to msg in XHDR inject code.
 If rename fails after 3 attempts the injector throws.

 20080416 - Version V2-9rc2.23.6

 Fixed bug where SNCY open() would fail on some Win* platforms with
 WSAEINVAL instead of the standard EINPROGRESS or EALREADY which were expected.
 Also added WSAEWOULDBLOCK to cover other "ambiguities" in windows sockets
 implementations. InProgress() on Win* now test for any of:

 WSAEINPROGRESS, WSAEALREADY, WSAEWOULDBLOCK, WSAEINVAL

 20080413 - Version V2-9rc2.22.6

 Fixed bug in TCPHost.open() where EALREADY was not counted as a version of
 EINPROGRESS. This would cause open() to throw an unnecessary exception when
 an open() required extra time.

 20080413 - Version V2-9rc2.21.6

 Extended timeout for SYNC session open() to the full session length. This way
 if a session takes a long time to open it still has a shot at success.

 20080411 - Version V2-9rc2.20.6

 Adjusted snfNETmgr to use non-blocking open in SYNC sessions. Open timeout
 is 1/3 of the session timeout. Session timeout is 2 * Session pacing. Open
 polling uses golden spiral delay from 10ms to 340ms.

 20080410 - Version V2-9rc2.19.6

 Adjusted XCI manager to use new snfCFGPacket paradigm in checkCFG().

 Adjusted snf_RulebaseHandler::addRulePanic() to use MyMutex and eliminated
 the AutoPanicMutex and waiting scheme.

 Refactored scanMessage() to use a ScopeMutex() rather than lock()/unlock().

 Refactored scanMessage() to use MyCFGPacket.isRulePanic() test.

 Redesigned snfCFGPacket handling to automate grab() / drop() functions.

 Fixed lock-up bug: Redesigned AutoPanic posting and checking mechanisms to 
 eliminate potential dead-lock condition. Under some conditions a precisely
 timed auto-panic posting could cause the RulebaseHandler mutex and the 
 AutoPanicMutex to become intertwined leading to a cascading deadlock. When
 this occurred all XCI processing threads and eventually the XCI listener
 thread would become blocked waiting to get the current configuration.

 20080409 - Version V2-9rc2.18.6

 Enhanced XCI exception handling and logging to provide additional detail.

 Added code to explicitely check for zero length files in scanMessagFile().
 Previously a zero length file would cause the CBFR module of the filter
 chain to throw an invalid buffer exception. Now if the message file is empty
 scanMessageFile() will throw a FileError stating FileEmpty!.

 20080407 - Version V2-9rc2.17.6

 Enhanced exception reporting in snfXCImrg


 20080405 - SNFServer V2-9rc2.16.6

 Reduced safetly limits on status reports to 100K for status reports and 100K
 for samples. Previous values were 10M. Most full sessions from the busiest
 systems are < 50K total.

 Recoded sendDataTimeout() to break uploads into 512 byte chunks and insert
 delays only when a chunk is fragmented. This methodology improves reliability
 on Win* systems without any significant penalty on systems that don't need
 socket sends() to be in smaller chunks.

 Fixed TCPClient::transmit() and TCPHost::transmit() bug where returned byte
 count might be -1. Now returned byte counts can only be 0 or more.

 20080403 - SNFServer V2-9rc2.15.5

 Minor modifications to networking module to better support non-blocking open()

 Updated SNFClient with new timing and non-blocking open(). Worst case return
 time from SNFClient estimated at 200 seconds (theoretically impossible). No-
 connection return time from SNFClient estimated at 20 seconds.

 20080326 - SNFServer V2-9rc2.15.4

 Refactored snfNETmgr::sync() to consolidate non-blocking io routines.

 Added detailed thread status data to XCI listener thread.

 Fixed minor bug in main (not changing revision), Debug flag for internal use
 was left on in the last build cycle. It is commented out now.

 20080325 - SNFServer V2-9rc2.14.4

 Updated snfNETmgr with comprehensive thread status data.

 Refactored snfNETmgr::sync() to check a Timeout, removed TCPWatchdog.

 20080325 - SNFServer V2-9rc2.13.4

 Upgraded TCPWatcher code to use new threading features (type, status).

 20080324 - SNFServer v2-9rc2.12.4

 Added a "Rulebase Getter" feature as part of the snf_Reloader. When enabled
 the Rulebase Getter will launch a user defineable system() call whenever a
 new rulebase file is available. The call will be repeated until the condition
 is cleared by a successful update of the rulebase file. The Rulebase Getter
 will wait a configurable "guard time" between attempts. The default system()
 call is "getRulebase" with a guard time of 3 minutes. In most cases this will
 launch the provided getRulebase script which should be present in the start
 location of SNFServer on most systems. Best practice is to configure the full
 path to the update script. The system() call is made in a separate thread so
 that if the system() call hangs for some reason only the Rulebase Getter is
 stuck.

 Built thread monitoring function for SNFServer.exe (Full status report / sec).
 The thread monitoring report is turned on when the program is renamed to
 SNFDebugServer.exe or if "debug" appears in the file path to the program.

 Refactored XCI channels to leverage new thread monitoring.

 Refactored Threading to eliminate inline code.

 Improved exception handling/reporting in scanMessageFile().

 Updated scanMessagFile() header injection code to accommodate messages with
 no body. Previous version would throw an exception when it could not find an
 injection point. The new version makes the injection point byte 0 and puts
 the injected headers at the top of the message using it's best guess about the
 type of line endings (CRLF or LF) to use.

 Updated Threading library to include high level thread state tracking and
 naming. Also creates a global Threads object that can produce a real-time
 status report on all threads.

 Updated Networking library to use SO_REUSEADDR by default on listeners.

 20080318 - SNF2-9rc1.11.exe Consolidated several mods/fixes

 Corrected scan error logging bug. Was posting <s/> now posts <e/>.

 Updated scan error logging to be more uniform with non-scan errors.

 Developed various script prototypes for postfix integration & automated
 updates on win* systems using the new UpdateReady.txt file mechanism.

 Fixed a bug in scanMessageFile() where an \n\n style insertion point
 would never be detected.

 Modified scanMessageFile() header injection to strip <CR> from line ends
 when the message file provided does not use them. The line-end style of
 the message file is detected while locating the insertion point. If the
 insertion point (first blank line) does not use <CR><LF> then the SNF
 generated X-Headers are stripped of <CR> in a tight loop before injection.

 Enhanced error and exception reporting in SNFMulti.cpp scanMessageFile().

 Enhanced exception handling in networking module. All exceptions now
 throw descriptive runtime_error exceptions.

 20080306 - SNF2-9rc1.8.exe (FIRST RELEASE CANDIDATE for VERSION 3!)

 Added Drilldown Header Directive Functions - When the candidate source IP
 comes from a header matching a drilldown directive the IP is marked "Ignore"
 in GBUdb and the candidate is no longer eligible to be the source for that
 message. This allows SNF to follow the trusted chain of devices (by IP) down
 to the actual source of the message. It is handy for ignoring net blocks
 because it can match partial IPs but it is designed to allow SNF to learn
 it's way through the servers at large ISPs so that the original source for
 each message can be evaluated directly.

 Added Source Header Directive Functions - This feature allows SNF to acquire
 the source IP for a message from a specific header rather than searching
 through the Received headers in the message. This is useful when the original
 source for a message is not represented in Received headers. For example:
 Hotmail places the originating source IP in a special header and does not
 provide a Received header for that IP. This feature is protected from abuse
 by a "Context" feature which only activates the source header directive when
 specific content is found in a specific received header. Using the above
 example, this feature can be configured so that a Hotmail source header would
 only be read if the top Recieved header contained "hotmail.com [" indicating
 that the ptr lookup for the header matched the hotmail domain. Note: When a
 source is pulled from a header directive that source is put into a synthetic
 Received header and injected into the scanning stream (not the message) as
 the first Received header.

 Added forced source IP to XCI - It is now possible to "inject" or "force"
 the source IP for any message by providing that IP in the XCI request or
 directly in a scan...() function call. This allows the calling application
 to provide the source IP for a message ahead of any Received headers that
 might be in the message. This is useful when the calling application knows
 the original source IP for the message but that IP is not represented in
 the Received headers and it is not desireable to use the Source Header
 Directive mechanism.

 Added forced source IP mode to SNFClient - It is now possible to call the
 SNFClient utility with an IP4Address using the syntax:

 SNFClient -source=12.34.56.78

 The -source mode of SNFClient exercises the forced source IP feature in
 the XCI (see above)

 Added Status Report features to SNFClient and XCI - It is now possible to
 request the latest status.second, status.minute, or status.hour data via
 the XCI and SNFClient. The syntax for requesting a status report using the
 SNFClient is:

 SNFClient -status.second
 SNFClient -status.minute
 SNFClient -status.hour

 In addition to providing status reports the SNFClient in this mode will
 return a nonzero value (usually 99) if it is unable to get a status report
 from SNFServer. This feature can be used to verify that SNFServer is up
 and responding. If SNFServer is OK then the result code returned is 0.

 Added result codes to SNFClient -test and XCI IP test functions - The XCI
 engine has been upgraded to provide the range value for the IP under test
 as well as the symbolic result code associated with that range. This allows
 the -test function to provide results that are consistent with the GBUdb
 configuration without additional processing: For example, if the IP falls
 in the Caution range then the Caution result code will be returned just
 as if a message had been scanned with the same IP and no pattern match
 occurred. The same is true for Truncate and Black range hits.

 Added Timestamp and Command Line Parameter data to SNFClient.exe.err - When
 an error occurs with SNFClient that may not appear in the SNFServer logs an
 entry is appended to the SNFClient.exe.err file. That in itself is not new.
 The new feature is that the entries added to the SNFClient.exe.err file now
 include timestamp and command line data to aid in debugging.

 Added BIG-ENDIAN Conversion - When the SNFServer program is compiled on a
 system that uses a BIG-ENDIAN processor (such as a power-mac) the rulebase
 load process now includes a routine to convert the token matrix from it's
 native LITTLE-ENDIAN format to a BIG-ENDIAN format. This solves a bug where
 Power-Mac (and presumably other BIG-ENDIAN systems) could compile and run
 the SNF* software but were unable to capture spam because the token matrix
 in the rulebase file was misinterpreted.

 Note: The BIG-ENDIAN Conversion feature is still considered experimental
 because it has not yet been thoroughly tested.

 Updated the Configuration Log to include all of the current configuration
 features and to improve it's readability.


 20080207 - SNF2-9b1.7.exe

 SYNC Timeout now 2x SYNC Schedule

 SNFServer now produces an UpdateReady.txt file when the UTC timestamp on
 the SYNC server is newer than the UTC timestamp of the active rulebase. It
 is presumed that a suitable update script or program will run periodically
 and download a fresh rulebase file if the UpdateReady.txt file is present.
 The update script should remove the UpdateReady.txt file when it completes
 a successful download of the new rulebase file.

 Added available rulebase UTC in status reports <udate utc.../>

 Added Automatic path fixup for ending / or \

 Added option to use local time in log rotation <rotation localtime='no'/>
 The default is still utc.

 20071102 - SNF2-9b1.6.exe

 Increased MAX_EVALS from 1024 to 2048.

 Adjusted defult range envelopes in snf_engine.xml to be more conservative.

 20071017 - SNF2-9b1.5.exe

 Added a missing #include directive to the networking.hpp file. The
 missing #include was not a factor on Linux and Windows systems but
 caused compiler errors on BSD systems.

 Corrected a bug in the GBUdb White Range code where any message with a
 white range source IP was being forced to the white result code. The
 engine now (correctly) only forces the result and records the event when
 a black pattern rule was matched and the White Range IP causes that
 scan result to be overturned. If the scan result was not a black pattern
 match then the original scan result is allowed to pass through.

 Corrected a bug in the Header Analysis filter chain module that would
 cause the first header in the message to be ignored in some cases.

 Corrected an XML log format problem so that <s/> elements are correctly
 open ended <s ....> or closed (empty) <s..../> according to whether they
 have subordinate elements.

 Adjusted the GBUdb header info format. The order of the Confidence
 figure and Probabilty figure is now the same as in the XML log files
 (C then P). The confidence and probability figures are now preceeded
 with c= and p= respectively so that it's easy to tell which is which.

 20071009 - SNF2-9b1.4.exe

 Tightened up the XCI handler code and removed the watchdog. The watchdog
 would restart the listener if there were no connections in 5 minutes. It
 was originally added to provide additional stability, however in practice
 there have been no "stalled listeners". Also, a stalled listener would
 likely be a sign of a different problem that the watchdog would tend to
 hide.

 Modified and refactored the XCI configuration management code. All XCI config
 changes and up-down operations are now handled in a single function except
 upon exit from the main XCI thread where XCI_shutdown() is always called.

 Added some more detailed exception handling code to the XCI component so that
 more data will be logged in the event of an error.


 20071008 - SNF2-9b1.2.exe

 Added support for passing Communigate Message Files directly. Communigate adds
 data to the top of the message file. That data stops at the first blank line and
 the rfc822 message begins. The SNFServer engine can now be told to ignore this
 extra data using the following option:

 <msg-file type='cgp'/> <!-- type='cgp'  for communigate message files -->

 If the msg-file type is anything other than 'cgp' then it will treat the message
 file as a standard rfc822 message in the usual way. The default setting is

 <msg-file type='rfc822'/>

       Developer notes for the SNFServer developer distribution

                           27 January 2009

 Scope
 -----

 This file contains information for software developers.  Ths
 information includes the prerequisite software for building, a
 description of the build system, and procedures for creating binary
 packages.

 Software prerequisites
 ----------------------

 The build system uses GNU software development system.  The following
 software is needed for building:

  1) automake

  2) autoconf

  3) libtool

  4) make

  5) g++

  6) tar

  7) curl

  8) pthread development.

 These tools are normally available on a Linux system that is
 configured as a software development system.  The Linux system
 installation process usually gives the user a choice of installing a
 workstation, server, or software development system.  However, not all
 Linux distributions give these choices.

 If these tools are not installed, they may be installed (or upgraded)
 at any time.  The commands vary from distribution to distribution.
 For Ubuntu, the apt-get command can be used:

  1) 'apt-get install automake'.

  2) 'apt-get install autoconf'.

  3) 'apt-get install libtool'.

  4) 'apt-get install make'.

  5) 'apt-get install g++'.

  6) 'apt-get install tar'.

  7) 'apt-get install curl'.

  8) 'apt-get install libc6-dev' (to install the pthread library).

 Structure of the build system
 -----------------------------

 The following files comprise the build system:

  1) configure.ac.  This is the main configuration file.  It specifies
  the distribution name, version, which libraries are needed, etc.

  2) Makefile.am.  This is used to create the top-level Makefile.  It
  lists which directories are part of the build system
  (e.g. SNFServer), and which extra files are to be part of the
  distribution (e.g. BUGS, README, etc).

  3) CodeDweller/Makefile.am.  This is used to create the Makefile for
  the CodeDweller library.  It lists which source files are to be used
  for building.

  3) SNFMulti/Makefile.am.  This is used to create the Makefile for
  the SNFMulti library.  It lists which source files are to be used
  for building.

  4) SNFClient/Makefile.am.  This is used to create the Makefile for
  SNFClient.

  5) SNF2Check/Makefile.am.  This is used to create the Makefile for
  SNF2Check.

  6) Scripts/Makefile.am.  This is used to create the Makefile for
  scripts (getRulebase, OS startup/shutdown, snfSniffer, etc).

 During the build process, the files in SNFMulti and CodeDweller are
 compiled into a static library.  The applications SNFServer,
 SNFClient, and SNF2Check link with these libraries.  This library is
 not installed.  The system checks the dates of the files, and
 recompiles and relinks as necessary.

 To add an additional source file , edit the appropriate Makefile.am.
 Add the source file to the appropriate variable.  For example, in
 SNFServer/Makefile.am:

  1) SNFServer_SOURCES for the cpp files for SNFServer.

  2) noinst_HEADERS for the header files for SNFServer.  These are
  part of the user tarball, but aren't installed into the user system.

 Note that files that are not listed will not be included in the
 distribution tarball.  This allows you to have additional files in
 directories (used, for example, for other projects) without
 unnecessarily increasing the size of the SNFServer application or
 tarball.

 Using the build system
 ----------------------

 Issue the following command to prepare system newly checked out for
 building:

  1) autoreconf --install

 Issue the following commands for building (the ./configure command
 needs options; see the INSTALL file or run './configure --help' for
 more info):

  1) ./configure --enable-os-type=Ubuntu --sysconfdir=/etc
  --prefix=/usr

  2) make

 The "./configure" command configures the system for installation into
 the default directory.  The default directory '/usr/local', but can be
 specified to be '/var/spool/snfilter' by adding the following line in
 configure.ac:

  AC_PREFIX_DEFAULT([/var/spool/snfilter])

 This can be overridden when running configure:

  ./configure --prefix=installation_directory

 where installation_directory is the directory to install the software.

 Other commands:

  "make dist" creates a tarball of the form snf-server-X.Y.Z.tar.gz.
  X, Y, and Z, as well as SNFServer, are specified by the following
  line in configure.ac:

    AC_INIT(snf-server, X.Y.Z)

  "make install" installs the software (currently copies SNFServer to
  the bin subdirectory of the installation directory.  I expect it
  will be modified to install other files (configuration files,
  scripts, etc).

  "make uninstall" removes the software from the installation
  directory.

  "make clean", "make distclean", "make maintainer-clean" remove files
  that can be recreated.  After running "make clean", you'd need to
  run "make" to rebuild the system.  After running "make distclean" or
  "make maintainer-clean", you'd need to run ./configure to build the
  system.

  "make dist" creates a tarball for the user.  The name is
  snf-server-X.Y.Z.tar.gz, and the files are extracted into the
  directory snf-server-X.Y.Z.

  "make distcheck" tests a user tarball.  This command extracts,
  configures, builds, and installs in temporary directories.  After
  verifying that each operation was successful, the command removes
  the temporary directories.

  "make maintainer-clean" removes many of the files that can be
  created.  After running this, you would need to run ./configure.

 Note: The script 'cleanForDist' cleans the developer distribution.  It
 removes any user tarballs that might have been created, files created
 by 'autoreconf --install', and files ending in "~".  After running
 this command, the directory tree can be imported into a version
 control system, or tarred and gzipped.

 Changing the version number or package name
 -------------------------------------------

 To change the version number or package name, do the following:

  1) Update configure.ac:

     a) Change the version number and/or package name for the build
     system.  Do this by modifying the argument to the AC_INIT line in
     configure.ac.  For example, to change the package name to FOO and
     the version to 8.0.2, modify the line to be:

       AC_INIT(FOO, 8.0.2)

 Build-time configuration parameters
 -----------------------------------

 The configure script accepts the following command-line parameters in
 addition to the standard parameters;

    --enable-os-type=TYPE

  where TYPE specifies the operating system for which SNFServer is to
  be configured.

 Generation of sample configuration files and scripts
 ----------------------------------------------------

 The build system generates sample configuration files and scripts that
 take into account where the SNFServer distribution is installed.  For
 example, if the distribution is built as follows:

  ./configure --prefix=/home/temp --enable-os-type=OpenBSD

 then the sample rulebase download script getRulebase.sample would
 download the rulebase to /home/temp/share/snf-server.  The other files
 (SNFServer.xml.sample, and SNFServer) would also be generated to take
 the specified prefix into account.

 Both SNFServer.exe and SNFClient.exe can be run in a debugging mode which
 produces additional output. In order to run these programs in debug mode
 you can rename them so that "debug" or "Debug" is in their name, or you
 can call them in a sub directory so that the path to the program conains
 "debug" or "Debug".

 SNFDebugClient.exe --

 The SNFClient.exe debug mode will display the entire XCI session for each
 call. This is a good way to see how XCI is used if you want to explore
 communicating with the SNFServer directly from your programs.

 SNFDebugServer.exe --

 The SNFServer.exe debug mode will display a thread status report each
 second along with the usual running statistics line. The thread status
 report will show all active theads, what they are doing (generally), and
 whether they are running or have stopped. If a thread stops due to an
 unhandeled exception then information about that exception will be
 displayed in the status report.

 There is a special version of the control script that will run the server
 in debug mode and capture it's output in a file called debuglog.

 20080325 -- At this time there are a few systems that are reporting an
 intermittent bug where SNFServer will either stop answering requests or
 it will stop reporting telemetry. When this happens there are no errors
 reported in logs, no exceptions thrown, no corrupted programs, nothing
 unusual at all --which is, of course, the most unusual thing of all. The
 program continues to run -- it's just not listening (or talking).

 On all but a handfull of systems SNFServer runs reliably for hundreds of
 days at a time without stopping until told to do so... This includes our
 lab computers... We hate mysteries -- the thread status report is designed
 to help us learn something about this bug since we are not yet able to
 reproduce it.

 To run SNFServer in debug mode, create a copy of SNFServer.exe named
 SNFDebugServer.exe and use the debugsnfctrl script to launch it (or you
 can launch it your own way -- the goal is to capture stdout and errout to
 a file called debuglog so that we can, hopefully, learn something).

 If you are not experiencing the bug then please run SNFServer.exe in the
 normal way.

 Thanks

 SNFClient Readme

 Command line client for SNF. This utility formats and processes SNF_XCI
 requests through the SNF Engine working on the local machine. In general
 this utility can be used as a replacement for the earlier SNF command
 line scanner. It is also useful for other uses such as debugging and
 communicating with GBUdb.

 Note: Unlike prior versions of SNF, this command line utility does not
 need to be "branded" (renamed for the SNF license id).

 _________
 Help Mode

 SNFClient.exe

  When called with no command line parameters the utility produces
  help and version information.

 __________
 Debug Mode

 SNFDebugClient.exe

  When "debug" or "Debug" appears in the path to the program name
  or if the program's name is altered to include the word "debug" or
  "Debug" then the program will produce additional information about
  it's operation to aid in debugging problems. This includes the
  entire raw SNF_XCI request and response.

 __________________
 Message Scan Modes

  These modes are used to scan email message files (the data part of
  smtp). This utility can be used as a drop-in replacement for previous
  verions of SNF (Message Sniffer) for scanning messages. However, this
  new version does not need to be "branded" (renamed for the license id)
  and will ignore the authentication string if it is provided. Also,
  since the newer version of SNF uses a client-server model and not a
  peer-server model, there is no need for a "persistent" mode.

  If "persistent" is passed to this utility on the command line as it
  would be used in prior versions of SNF then it will be treated like
  a file name and the scan will normally fail since a file named
  "persistent" is not likely to exist.

 SNFClient.exe <FileNameToScan>

  Scan Mode: Scans <FileNameToScan> and returns a result code.

 SNFClient.exe <authenticationxx> <FileNameToScan>

  Compatibility Mode: Ignores <authenticationxx> then scans the
  <FileNameToScan> and returns a result code. This mode provides
  drop-in compatibility with previous versions of SNF.

 SNFClient.exe -xhdr <FileNameToScan>

  XHeader Mode: Scans <FileNameToScan> and returns the result. Also
  outputs the contents of the X-Headers created by the SNF engine. If
  the SNF engine is configured to inject these headers then they will
  also have been injected into the <FileNameToScan>.

  The SNF Engine can be configured to provide the X-Headers only to
  the API without injecting them. In this case the XHeader Mode will
  display the X-Headers that would be injected, but they will not
  have been injected into the <FileNameToScan>.

  If the SNF Engine is configured not to produce X-Headers (none) then
  the XHeader Mode will not produce X-Headers because they will not
  have been generated by the engine.

  (note: -xhdr and -source options can be combined)


 SNFClient.exe -source=<IP4Address> <FileNameToScan>

  Source-IP Mode: Scans <FileNameToScan> and returns the result. The
  provided source IP is injected into the scan as the first Received
  header so that the scanning engine will presume the IP is the source
  of the message. This allows you to pre-define the source IP for the
  message when there is no other received header or when the received
  headers may be incorrect or may not present the actual source of
  the message.

  (note: -xhdr and -source options can be combined)

 _____________________________
 SNFServer Status Report Modes

 SNFClient.exe -status.second
 SNFClient.exe -status.minute
 SNFClient.exe -status.hour

  This mode returns the latest posted status report as indicated.
  Normally these status reports are also posted to files in the
  SNFServer workspace.

  In this mode the SNFClient will return a result code (error level)
  of 0 when the request is successful and 99 (or some nonzero value)
  when the request is not successful. This allows the SNFClient to
  be used to verify that the SNFServer is running.

  Note: In most other modes the SNFClient returns a fail-safe 0
  result code to avoid tagging messages as spam when there are errors.

 ________________________
 XCI Server Command Modes 

 These features will expand as needed in later versions.

 SNFClient.exe -shutdown

  If the SNF Engine is running in an application that accepts SNF_XCI
  server commands then this mode will send that command. The shutdown
  command may have no effect if the application does not use the SNF_XCI
  server commnand interface or does not recognize the command.

 ___________
 GBUdb Modes

  These modes are used to communicate with the GBUdb system on the
  local node. It is possible to test (read out) an IP record or make
  any of a number of changes to IP data in the GBUdb.

 SNFClient.exe -test <IP4Address>

  Returns the current GBUdb statistics for the <IP4Address>

  SNFClient also returns a result code that matches the GBUdb range
  for the tested IP. These ranges are defined in the SNFServer
  configuration file. By default they are:

  20 - Truncate
  63 - Black
  40 - Caution
   0 - Normal

 SNFClient.exe -set <IP4Address> <flag> <bad> <good>

  Creates or updates the data for <IP4Address> as provided. The
  <IP4Address> must be provided as well as at least one of
  <flag>, <bad>, and <good>. If <flag>, <bad>, or <good> are
  to be left unchanged then they should be entered as a dash "-".

  Examples:

  Set all data for an IP. The flag will be "ugly", the bad count
  will be 0 and the good count will be 1000.

  SNFClient.exe -set 12.34.56.78 Ugly 0 1000

  Set the flag to "ignore" and do not change the counts.

  SNFClient.exe -set 12.34.56.78 ignore - -

  Set the good count to 400 and do not change anything else.

  SNFClient.exe -set 12.34.56.78 - - 400

 SNFClient.exe -good <IP4Address>

  Creates or updates statistics for the <IP4Address>. Increases the
  good count by one. (Record a good event)

 SNFClient.exe -bad <IP4Address>

  Creates or updates statistics for the <IP4Address>. Increases the
  bad count by one. (Record a bad event)

 SNFClient.exe -drop <IP4Address>

  Removes all local data for the <IP4Address>. Anything the local
  system "knows" about the IP is forgotten. Next time the IP is
  encountered it will be treated as new.

 SNF_Server V3.0 installation brief

 This is a generalized guide. For specific platform guides see:
 http://www.armresearch.com/support/articles/installation/index.jsp

 Create a directory for SNF_Server. ( c:\SNF or /var/spool/snfilter )

 Copy all of the files to that directory.

 Make a copy of the SNFServer<version>.exe file and give it the name
 SNFServer.exe. Later on if newer versions are provided you will
 be able to keep track of them by name and swap newer versions into
 place by copying them over your SNFServer.exe file. If you decide
 you have to go back to a previous version then you will be able to
 do that easily by deleting your SNFServer.exe file and copying the
 version you wish to use into place.

 Modify the identity.xml file to match your SNF license ID and your
 authentication string.

 Download your .snf file and place that in the SNF_Server working
 directory.

 RULEBASE UPDATES (NEW!): The latest version of the SNFServer engine
 includes a mechanism that will run an a script when the rulebase file
 on our server is newer than the active file in SNF. By default this
 feature is configured to run the included getRulebase script. If
 the script is not successful it will be launched again every 3 minutes
 until the rulebase file is successfully updated.

 Be sure to modify the top of the getRulebase script to include
 your correct license ID, authentication string, and working directory.

 Be sure to verify that the <update-script/> section of your
 SNFServer.xml file is correct (points to the correct location of
 getRulebase).

 getRulebase uses wget and gzip (included for your convenience in 
 the Win* distribution. See About-Wget-and-Gzip.txt.). These are open
 source utilities for downloading files from web servers and unzipping
 those files -- in this case, SNF rulebase files.  

 If you have any gateways or other internal systems that will relay
 mail to SNF then include their IPs in GBUdbIgnoreList.txt. The GBUdb
 component of SNF uses the IPs in this list to determine the actual
 source IP for a message by reviewing the Received headers. Each
 Received header is evaluated in turn. If the source (connect) IP is
 found in the Ignore list then that Received IP is considered to be
 part of your infrastructure and is ignored. The first Received IP 
 found that is NOT in the Ignore list is selected as the source IP.

 The GBUdbIgnoreList is a "safety net" that ensures the listed IPs are
 present in your GBUdb with their Ignore flag set. It is loaded every
 time the configuration is changed, SNFServer is started, or a new
 rulebase is loaded. This way if your GBUdb database is lost then your
 critical infrastructure will be re-listed in the new .gbx file that
 is created.

 The ignore list allows only SINGLE IP ENTRIES. This can be a problem
 in some cases - such as when you want to ignore large blocks of network
 addresses.

 SNF can learn to Ignore large blocks of IPs using the <drilldown/>
 feature. For example if you want to ignore all of 12.34.56.0/24 then
 you can make an entry in the <drilldown/> training section like this:

 <training on-off='on'>
  ...
  <drilldown>
    <received ordinal='0' find='[12.34.56.'/>
  </drilldown>
  ...
 </training>

 GBUdb learns the behavior of source IPs so it is important that GBUdb
 knows any friendly sources that might send spammy messages to your
 server or else it will learn that those sources are not to be trusted.

 Since not all friendly spam sources can be identified by IP ahead of
 time, there are features in the <training/> section of SNFServer.xml
 that allow you to adjust the training scenarios to compensate. The
 most likely of these is that you may wish to bypass training for
 messages that are to your support addresses or spam submission
 addresses. For example:

 <training on-off='on'>
  ...
  <bypass>
    <header name='To:' find='support@example.com'/>
    <header name='To:' find='spam@example.com'/>
  </bypass>
  ...
 </training>

 Evaluate the SNFServer.xml file carefully. In most cases the
 default settings are appropriate, however you may want to alter
 some of the settings to match your system policies or particular
 installation.

 IMPORTANT: Be sure that any file paths / directories referenced in
 the configuration file exist on your system and that SNF has full
 access rights to these - especially the SNF working directory.

 ** If you selected a working directory for SNF other than c:\SNF\
 then be sure you have changed these paths in the top of your
 SNFServer.xml file. Pay close attentiont to these 5 elements:

 <node identity='c:/SNF/identity.xml'>
 <log path='c:/SNF/'/>
 <rulebase path='c:/SNF/'/>
 <workspace path='c:/SNF/'/>
 <update-script ... call='c:/SNF/getRulebase.cmd' ... />

 Once you are happy with your configuration and you have all of your
 files and directories in place (including your .snf file) then you
 can start SNF_Server.

 The command line (from inside the SNF workspace) is:

 SNFServer SNFServer.xml

 That is: SNFServer <configuration>

 If you want to lauch SNFServer from some other location it would be
 best to use the entire path for both the SNFServer engine and the
 configuration file (Microsoft Windows example):

 c:\SNF\SNFServer.exe c:\SNF\SNFServer.xml

 or

 /usr/sbin/SNFServer /etc/SNFServer/SNFServer.xml

 You should begin by testing SNFServer by running it in a command line
 window where you can watch it's output.

 Once you are happy with it then you will probably want to run it as
 a service using a utility such as the srvany utility from the win2k 
 toolkit, or detached as a daemon on *nix systems (snfctrl file example
 included).

 This section of our site might be helpful:

 http://www.armresearch.com/support/articles/installation/serviceSetup/index.jsp

 SNFServer is the server side of a client/server system. In order to
 scan messages you will need to use the client utility (SNFClient.exe
 or SNFIMailShim.exe) to scan messages.

 SNFClient.exe is a drop-in replacement for the production (2-3.x)
 SNF program when it is called from Declude or mxGuard or other similar
 software. There is no need to "brand" the SNFClient.exe
 program and it is not necessary to include the authentication string
 on the command line -- however, if you do it will be accepted and
 ignored without an error.

 SNFServer MUST be running for SNFClient to work. If SNFClient cannot
 reach SNFServer then it will wait for quite a while as it attempts to
 make contact.

 Here are a few ways to call SNFClient.exe:

 SNFClient.exe -shutdown

 	Sends the Shutdown command to the SNF_Server.

 SNFClient.exe authenticationxx filetoscan

 	Compatibility mode - ignores authenticationxx and scans filetoscan.

 SNFClient.exe filetoscan

 	Normal scan mode - scans filetoscan.

 SNFClient.exe -xhdr filetoscan

 	XHDR scan mode - scans filetoscan and returns X Headers.

 See the SNFClient_Readme.txt file for details.

 The SNF Client/Server pair communicate using short XML messages via a local
 TCP connection (typically to port 9001). Examples of SNF_XCI messages are
 included in snf_xci.xml (not a well formed xml file! - just some examples).

 It is possible to communicate directly with the SNF_Server engine via TCP
 from your software using the SNF_XCI (SNF XML Command Interface) protocol. The
 server expects to see one connection per request. The client sends an SNF_XCI
 request to the server. The server responds with an appropriate SNF_XCI
 formatted response and terminates the connection.

 Requests and responses are expected to terminate with a newline character.

 You can see the XCI protocol at work by running the SNFClient in debug mode
 (SNFdebugClient).

               SNFServer Installation and Configuration

              Copyright (C) 2008 ARM Research Labs, LLC.

           See www.armresearch.com for the copyright terms.
                                   
 Installing SNFServer to filter email involves the following steps:

  1) Check prerequisites.

  2) Create the snfilter user and group.

  3) Build and install the SNFServer package (using a tarball or a
  package).

  4) Configure the SNFServer package.

  5) Interface with the MTA (postfix or sendmail).

  6) Configure the OS to start and stop SNFServer on bootup and
  shutdown.

 The following sections describes each of these steps for a default
 installation.  Any OS-specific issues are described at the end of each
 section.

 Prerequisites
 *************

 Before installing SNFServer, make sure that:

  1) The program curl must be installed.

 Creating the snfilter user and group
 ************************************

 Before installing, the snfilter user and group must be created.  For
 increased security, snfilter user has no shell.

 OS-specific issues--

 The commands to create the snfilter user and group are OS dependent.
 For your convenience, the commands for creating the user and group for
 varous OSes are listed here.  However, no guarantee is made that these
 commands will work on your system; please refer to your system
 documentation.

  1) OpenBSD:

     a) 'useradd -g =uid -m -c "SNFServer Account" -s /bin/false snfilter'.

  2) Ubuntu:

     a) 'adduser --gecos "SNFServer Account" --no-create-home --shell /bin/false snfilter'.

  3) RedHat (and variants such as Fedora and CentOS):

     a) 'adduser --comment "SNFServer Account" -M --shell /bin/false snfilter'

  4) Suse:

     a) 'groupadd snfilter'

     b) 'useradd -c "SNFServer Account" -s /bin/false -g snfilter snfilter'

  5) FreeBSD:

     a) 'pw user add -c "SNFServer Account" -n snfilter -w no -s /bin/false'

 Building and installing SNFServer
 *********************************

 For some operating systems, configuration files are normally installed
 in /etc, and the installation of the remaining files are in /usr
 (i.e. /usr/sbin, /usr/share/snf-server, etc).  In other operating
 systems, the files are installed in /usr/local/etc or /usr/local.

 The directories to install are specified by the '--prefix' and
 '--sysconfdir' options to the configure script (see below).

 To build and install from the tarball--

  1) Extract the distribution from the tarball: 'tar xvzf
  snf-server-X.Y.Z.tar.gz', where X.Y.Z is the version of the
  distribution.

  1) 'cd' to the source directory.

  2) Run the configure script.  See the section on OS-specific issues
  for the options to specify.  This configures the package.

  3) Type 'make'.  This builds the package.

  4) Type 'make install'.  This installs the package in the default
  directories.

 The following files are installed:

  Executables and scripts in sbin:
       SNFServer
       SNFClient
       SNF2Check
       getRulebase.sample
       snfSniffer.sample
       snfSnifferFilter.sample
       snfscan-standalone.sample
       snfServerControl.sample

  Sample configuration files in etc/snf-server:
       SNFServer.xml.sample
       identity.xml.sample

  In share/snf-server
       GBUdbIgnoreList.txt.sample

 During operation of SNFServer, the following files are created:

  In share/snf-server:
       *.snf
       Log files
       UpdateReady.txt
       Temporary files

 OS-specific options for ./configure:

  1) OpenBSD:

    ./configure --enable-os-type=OpenBSD --sysconfdir=/etc

  2) FreeBSD:

    ./configure --enable-os-type=FreeBSD

  3) Ubuntu:

    ./configure --enable-os-type=Ubuntu --sysconfdir=/etc --prefix=/usr

  4) RedHat (and variants such as Fedora and CentOS):

    ./configure --enable-os-type=RedHat --sysconfdir=/etc --prefix=/usr

  5) Suse:

    ./configure --enable-os-type=Suse --sysconfdir=/etc --prefix=/usr

 Configuration
 *************

 Configuration consists of creating the configuration files used by
 SNFServer from the sample configuration files of the distribution.
 There are three configuration files.  The location of the files
 described in this section are for the installation in /usr and /etc.

 Two of the files are in /etc/snf-server:

  1) SNFServer.xml (sample configuration file is
  SNFServer.xml.sample).

  2) identity.xml (sample configuration file is identity.xml.sample).

 and one in /usr/share/snf-server:

  1) GBUdbIngoreList.txt (sample configuration file is
  GBUdbIgnoreList.txt.sample).

 To configure SNFServer, do the following:

  1) Copy SNFServer.xml.sample to SNFServer.xml, and edit as follows:

     a) Specify the directories.  The default directories are:

          <node identity='/etc/snf-server/identity.xml'>
          <log path='/usr/share/snf-server/'/>
          <rulebase path='/usr/share/snf-server/'/>
          <workspace path='/usr/share/snf-server/'/>
          <update-script on-off='on' call='/usr/sbin/getRulebase'
                         guard-time='180'/>

     The paths need to be changed only if the default directories are
     not used.

     If desired for security purposes, restrict the permissions of
     SNFServer.xml.  For example, to make SNFServer.xml readonly by
     only the snfilter user and snfilter group, enter the following:

       chmod 440 SNFServer.xml

  2) Copy identity.xml.sample to identity.xml, and edit to include the
  license ID and authentication attributes of the <identity> element.
  If desired for security purposes, restrict the permissions of
  identity.xml.  For example, to make identity.xml readonly by only
  snfilter, enter the following:

    chmod 400 identity.xml

  3) Copy GBUdbIngoreList.txt.sample to GBUdbIgnoreList.txt, and edit
  as appropriate (the file format is described in the comments in the
  file).  See README for more information on this file.

  4) In the directory for the update script specified in the
  configuration file (default: /usr/sbin):

     a) Copy getRulebase.sample to getRulebase, and edit as follows:

       i) In the line

            AUTHENTICATION=authenticationxx

          replace authenticationxx with the authentication for the
          SNFServer license.
          
       ii) In the line

            LICENSE_ID=licenseid

          replace licenseid with the license ID of the SNFServer
          license.

       iii) Any other changes as necessary if the default directories
       are not used.

     b) Ensure that getRulebase is executable by the snfilter user.
     This can be done with the command:

       chmod +x getRulebase

  5) Ensure that the snfilter user has read/write access to the files
  in workspace (default: /usr/share/snf-server or
  /usr/local/share/snf-server) and configuration directory (default:
  /etc/snf-server).  To grant this access, enter the following command,
  as the root user:

    chown -R snfilter:snfilter /usr/share/snf-server

    chown -R snfilter:snfilter /etc/snf-server

  As you modify files in these directories, please ensure that the
  read/write permissions for snfilter is maintained.

  4) Download the rulebase file:

     a) 'cd /usr/share/snf-server'.  If the workspace specified in the
     configuration file is not the default, this command should be
     changed accordingly.

     b) 'touch UpdateReady.txt'.

     c) 'chown snfilter UpdateReady.txt'.

     d) 'su -m snfilter -c "/usr/sbin/getRulebase"'.  If getRulebase
     is in a different directory, this command should be changed
     accordingly.

 OS-specific issues--

  None.

 Configuring the OS
 ******************

 The OS can be configured to automatically start and stop SNFServer on
 system startup and shutdown.  The following gives the procedure for
 each OS:

 OpenBSD:

  1) Add the following line to /etc/rc.local:

       /usr/local/sbin/snf-server start

  2) Add the following line to /etc/rc.shutdown:

       /usr/local/sbin/snf-server stop

  3) Run '/usr/local/sbin/snf-server start' to start the server.

 FreeBSD:

  1) Create the directory /etc/rc.conf.d (if it doesn't exist).

  2) Create the file /etc/rc.conf.d/snfsrver with the contents:

       snfserver_enable="YES"

  3) Run '/usr/local/etc/rc.d/snf-server start' to start the server.

 Ubuntu:

  1) Set the VERBOSE variable in /etc/default/rcS to control the
  script output.

  2) Configure the system to run the script using the appropriate
  procedure.

  3) Run '/etc/init.d/snf-server start' to start the server.

 RedHat (and variants such as Fedora) and Suse:

  1) Run 'chkconfig --add snf-server'.  This sonfigures the system to
  run the script on startup and shutdown.

  2) Run 'chkconfig --list snf-server' to display the runlevels

  3) Run 'service snf-server start' to start the SNFServer.

 Integration with MTAs
 *********************

 The section assumes you will be using SNFServer with an MTA and simply
 injecting headers that will be used later to remove, quarantine, or
 otherwise redirect messages detected as spam. There are as many ways
 to use SNFServer as there are systems using it -- so the following is
 just a good starting point.

 It is presumed that SNFServer is configured with x-header injection
 turned on and that the x-headers have been customized to suit your
 needs. Check the <xheaders/> section of your
 /etc/snf-server/SNFServer.xml file to verify that SNFServer is
 configured to do what you want.

 Integration with postfix
 ------------------------

 One way to integrate with postfix is to configure postfix to use the
 snfSniffer script (described below) as a content filter.  The
 snfSniffer script passes the message through SNFServer, and then
 reinjects the message into the mail system.

  1) In /usr/sbin (or /usr/local/sbin), copy the script
  snfSniffer.sample to snfSniffer set the correct access rights:

    cp snfSniffer.sample snfSniffer

    chown snfilter snfSniffer

    chmod 550 snfSniffer

 The default snfSniffer script creates a temporary copy of the message,
 scans it with SNFServer, and then reinjects the message.

   2) Change /etc/postfix/master.cf as follows (LEADING WHITE SPACES
   ARE IMPORTANT WHEN MAKING THIS CHANGE):

   change (each line is enclosed in single quotes; add only the text
   between the single quotes):

      'smtp      inet  n       -       n       -       -       smtpd'

   to:

       'smtp      inet  n       -       n       -       -       smtpd'
       '     -o content_filter=snfilter:dummy'


    also add:

       'snfilter  unix  -       n       n       -       10      pipe'
       '     flags=Rq user=snfilter argv=/usr/sbin/snfSniffer'
       '     -f ${sender} -- ${recipient}'

    to master.cf.  Specify the directory snfSniffer is in if not
    /usr/sbin.

 At this point you could just restart postfix, and hope nothing goes
 wrong. Instead, it would be smarter to first test the installation
 from the command line by injecting a message directly into the filter
 script "snfSniffer".  We can issue a command like (in directory
 /usr/share/snf-server):

  /usr/sbin/snfSniffer -f sender recipient < junkmsg.txt

 Where junkmsg.txt is a spam test message. We should also test
 a clean message to make sure that this script is working as we
 expect it to.  In this case we would issue a command like

  /usr/sbin/snfSniffer -f sender recipient < cleanmsg.txt

 If you've done everything correctly then all you have to do is reload
 postfix to start the content_filter working.

   4) 'postfix reload'.  Restart postfix.

   5) To stop using the snfSniffer filter:

      i) Comment out or remove the '-o content_filter=snfilter:dummy'
      line in the /etc/postfix/master.cf file.

      ii) 'postsuper -r ALL' to remove content filter request records
      from existing queue files.

      iii) 'postfix reload' to reload the postfix configuration.

 OS-specific issues--

  1) OpenBSD:  In the default postfix configuration for OpenBSD, the
  postfix programs run chrooted in /var/spool/postfix.  For that
  configuration, the /etc/pwd.db file needs to be made available to
  the postfix programs.  This can be done by copying pwd.db:

    cp /etc/pwd.db /var/spool/postfix/etc

  If the /etc/pwd.db file is modified after copying, the postfix
  system issues a warning.  To avoid this warning, copy the
  /etc/pwd.db file to /var/spool/postfix/etc directory whenever
  /etc/pwd.db is modified.

 Integration with sendmail
 -------------------------

 One way to integrate with send is to configure sendmail to use the
 snfSnifferFilter script (described below) as a filter.  The snfSniffer
 script passes the message through SNFServer, and then sends the
 message to stdout.  The integration is done by having sendmail use
 procmail to filter all mail (which is normally the default), and
 configuring procmail to use snfSnifferFilter as a filter.

  1) In /usr/sbin (or /usr/local/sbin), copy the script
  snfSnifferFilter.sample to snfSnifferFilter set the correct access
  rights:

    cp snfSnifferFilter.sample snfSnifferFilter

    chown snfilter snfSnifferFilter

    chmod 550 snfSnifferFilter

 The default snfSnifferFilter script creates a temporary copy of the
 message, scans it with SNFServer, and then send the message to
 stdout.

   2) Verify that sendmail is configured to use procmail to deliver
   mail.  Please see the sendmail and procmail documentation for how
   to do this.

   3) Create the file /etc/procmailrc (or whatever the system procmail
   rcfile is; see the procmail documentation for the path on your
   system) to contain the following lines:

     ':0 fw'
     '| /usr/sbin/snfSnifferFilter'

   where the single quotes are not to be included.

 At this point mail should be filtered by SNFServer.  To check this,
 issue a command like (in directory /usr/share/snf-server):

  /usr/sbin/snfSnifferFilter < junkmsg.txt

 Where junkmsg.txt is a spam test message.  We should also test a clean
 message to make sure that this script is working as we expect it to.
 In this case we would issue a command like

  /usr/sbin/snfSnifferFilter < cleanmsg.txt

 In either case you should see the message with the headers added by
 SNFServer.

   4) To stop using the snfSnifferFilter:

      i) Comment out or remove the two lines you added to /etc/procmailrc.

 OS-specific issues--

  1) OpenBSD: The default sendmail confiugration might not use
  procmail.  To configure sendmail to use procmail, please ensure that
  procmail is installed and see the procmail documentation
  (/usr/local/share/examples/procmail/advanced) for the procedure to
  integrate procmail as an integrated local mail delivery agent.

  By default, procmail is installed in /usr/local/bin, and the system
  procmail rcfile is /etc/procmailrc.

  After you make the changes, stop sendmail with 'pkill sendmail', and
  start it with 'sendmail -bd'.

  2) FreeBSD: The default sendmail confiugration might not use
  procmail.  To configure sendmail to use procmail, please ensure that
  procmail is installed and see the procmail documentation
  (/usr/local/share/examples/procmail/advanced) for the procedure to
  integrate procmail as an integrated local mail delivery agent.

  By default, procmail is installed in /usr/local/bin, and the system
  procmail rcfile is /usr/local/etc/procmailrc.

  After you make the changes, restart sendmail with
  '/etc/rc.d/sendmail restart'.

  3) RedHat, Fedora, Centos, Suse, and Ubuntu: Restart sendmail with
  '/etc/init.d/sendmail restart'.

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
 software and other kinds of works.

  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 the GNU General Public License is intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.

  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.

  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
 modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
 works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
 on the Program.

  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.

  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.

  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.

  The Corresponding Source for a work in source code form is that
 same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.

  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.

  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.

  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.

  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.

  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).

  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.

  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.

  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:

    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or

    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or

    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or

    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or

    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.

  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.

  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.

  8. Termination.

  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).

  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.

  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.

  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.

  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.

  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".

  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.

  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.

  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.

  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.

  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.

  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.

  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
 the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.

  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.

  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.

    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <http://www.gnu.org/licenses/>.

 Also add information on how to contact you by electronic and paper mail.

  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:

    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".

  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <http://www.gnu.org/licenses/>.

  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

 	Developer notes for the SNF4SA developer distribution

 			    30 April 2009

 Scope
 -----

 This file contains information for software developers.  Ths
 information includes the prerequisite software for building, and a
 description of the build system.

 Introduction
 ------------

 The purpose of the build system is to create a user tarball.  The
 files don't need to be compiled or linked, and the user is responsible
 for intalling and removing the files.  Therefore, the build system
 doesn't include any functionality for building, installing, or
 uninstalling; the "make install" command does nothing.

 See the section "Using the build system" for commands to initialize
 the build system and create a user tarball.

 Software prerequisites
 ----------------------

 The build system uses GNU software development system.  The following
 software is needed for building:

  1) automake

  2) autoconf

  3) make

  4) tar

 These tools are normally available on a Linux system that is
 configured as a software development system.  The Linux system
 installation process usually gives the user a choice of installing a
 workstation, server, or software development system.  However, not all
 Linux distributions give these choices.

 If these tools are not installed, they may be installed (or upgraded)
 at any time.  The commands vary from distribution to distribution.
 For Ubuntu, the apt-get command can be used:

  1) 'apt-get install automake'.

  2) 'apt-get install autoconf'.

  3) 'apt-get install make'.

  4) 'apt-get install tar'.

 Structure of the build system
 -----------------------------

 The following files comprise the build system:

  1) configure.ac.  This is the main configuration file.  It specifies
  the distribution name, version, which libraries are needed, etc.

  2) Makefile.am.  This is used to create the top-level Makefile.  It
  lists which files and directories are part of the build system
  (e.g. snf4sa.cf), and which extra files are to be part of the
  distribution (e.g. README, etc).

 To add an additional file , edit Makefile.am.  Add the file to the
 appropriate variable (for example, to EXTRA_DIST).

 Note that files that are not listed will not be included in the
 distribution tarball.  This allows you to have additional files in
 directories (used, for example, for other projects) without
 unnecessarily increasing the size of the SNFServer application or
 tarball.

 Using the build system
 ----------------------

 Issue the following command to prepare system newly checked out for
 building:

  autoreconf --install

 Then issue the following command for configuring the build system:

  ./configure

 To create a user tarball:

  make dist

 This creates a tarball with the name snf4sa-X.Y.Z.tar.gz.  X, Y, and Z, as well as "snf4sa" are specified by the following line in configure.ac:

  AC_INIT(snf4sa, X.Y.Z)

 Other commands:

  "make maintainer-clean" removes many of the files that can be
  created.  After running this, you would need to run ./configure.

 Note: The script 'cleanForDist' cleans the developer distribution.  It
 removes any user tarballs that might have been created, files created
 by 'autoreconf --install', and files ending in "~".  After running
 this command, the directory tree can be imported into a version
 control system, or tarred and gzipped.

 Changing the version number or package name
 -------------------------------------------

 To change the version number or package name, edit configure.ac as
 follows:

  Change the version number and/or package name for the build system.
  Do this by modifying the argument to the AC_INIT line in
  configure.ac.  For example, to change the package name to FOO and
  the version to 8.0.2, modify the line to be:

     AC_INIT(FOO, 8.0.2)

               SpamAssassin SNF4SA Plugin for SNFServer
                    Installation and Configuration

              Copyright (C) 2009 ARM Research Labs, LLC.

           See www.armresearch.com for the copyright terms.
                                   
 Installing SpamAssassin SNF4SA plugin for SNFServer involves the
 following steps:

  1) Copy snf4sa.pm and snf4sa.cf to /etc/mail/spamassassin .

  2) Edit /etc/mail/spamassassin/snf4sa.cf plugin configuration file
  to meet your needs.  See below for a description of the
  configuration settings.

 The module writes the email message to a temporary file in
 /tmp/snf4sa.  If this directory doesn't exist, the script creates it
 with permission 777.  This allows both the script and SNFServer to
 write to that directory.  If that directory already exists, ensure
 that it has a permission of 777.

 Plugin Configuation Settings
 ----------------------------

 The plugin file (snf4sa.cf) contains required lines that:

  1) Configures SpamAssassin to load the plugin.

  2) Describes the plugin.

  3) Configures SpamAssassin to add the X-Spam-SNF-Result header to
  the email.  This header contains the results of the SNF scan.

 In addition, there are lines that can be configured by the user that
 specifies:

  1) Which emails to process through SNFServer.

  2) The relationship between SNFServer results and the SpamAssassin
  score.  You can specify the value added to or subtracted from the
  SpamAssasin score for each SNFServer result.  You can also specify
  whether SpamAssasin should abort further processing for eacn
  SNFServer result.

  3) The relationship between the GBUdb results and the SpamAssassin
  score.  The GBUdb probability p and confidence c add the following
  value to the SpamAssasin score:

    abs(p * c) ^ 0.5 * sign(p) * MaxWeight

  where sign(p) is -1 if p < 0, and +1 otherwise, and MaxWeight is
  specified in a configuration line.  MaxWeight is greater than or
  equal to zero.  If MaxWeight isn't specified in the configuration
  file, then the GBUdb results don't affect the SpamAssassin score.

 To specify which emails to process, use a line similar to:

  full SNF4SA eval:snf4sa_sacheck()

 The above line specifies that all emails be processed.  Please see the
 SpamAssassin documentation for other options.

 To specify the relationship between the SNFServer results and the
 SpamAssassin score, enter zero or more lines with the format:

  snf_result NN sa_score S short_circuit_[yes|no]

 where NN specifies the SNFServer result, and S is the SpamAssassin
 score for that SNFServer result.  [yes|no] is "yes" if further
 scanning should be skipped if SNFServer returns the result specified
 by NN, or "no" if further scanning should not be skipped.  NN can be a
 combination of a series of one or more integers, and a range of
 integers specified by N-M, where N and M are integers.  The
 "short_circuit_[yes|no]" is optional, and the default value for
 [yes|no] is "no" (which specifies that SpamAssasin continue scanning).

 NOTE: There must not be any space when specifying a range of integers.
 For example, specify "34-43" rather than the incorrect "34 - 43".

 For example:

  snf_result 63 sa_score 2.5 short_circuit_no

 causes the plugin to add 2.5 to the SpamAssassin score if SNFServer
 returns 63 (which in the default SNFServer configuration corresponds
 to "caution").

 Another example:

  snf_result 45 47-62 sa_score 5.0 short_circuit_yes

 causes the plugin to add 5.0 to the SpamAssassin score and stop
 further processing if SNFServer returns 45 or 47 thru 62.

 Final example:

  snf_result 1 sa_score -5.0

 causes the plugin to subtract 5.0 from the SpamAssassin score.
 SpamAssassin continues to process the email.

 If SNFServer returns a result that isn't specified, then the plugin
 adds zero to the SpamAssassin score.

 The following line specifies the MaxWeight parameter:

  GBUdb_max_weight MaxWeight

 where MaxWeight is the value to specify.  For example,

  GBUdb_max_weight 3.0

 specifies a MaxWeight value of 3.0.

 Debugging the configuration
 ---------------------------

 The configuration can be tested by running

    spamassassin --lint

 This outputs a message if any line in in the configuration file cannot
 be parsed, along with the offending line.

 In order to obtain more detailed information, run

   spamassassin -D --lint

 This command outputs information about why a line could not be parsed.
 The output includes a great deal of other debugging information; you
 can filter the information relevant to this plugin like this:

   spamassassin -D --lint 2>&1 | grep snf4sa

 This directory contains the SpamAssassin plugin for SNFServer.

 The plugin implements a rule that checks the email message with
 SNFServer.

 If SNFServer determines that the email message is spam, then
 SpamAssassin increments the score by an amount that depends on the
 SNFServer result.  The amount to add for each SNFServer result is
 specified in the configuration file.

 The GBUdb scan result also changes the score by:

  abs(p * c) ^ 0.5 * sign(p) * MaxWeight

 where p is the probability and c is the confidence returned by the
 GBUdb scan, sign(p) is -1 if p < 0 and +1 otherwise, and MaxWeight is
 specified in the configuration file.  If SNFServer is not configured
 to insert the GBUdb scan results into a header in the message, or
 MaxWeight is not specified in the configuration file, then the
 SpamAssassin score is not affected by the GBUdb scan results.

 In addition to scanning the message, the plugin inserts headers into
 the email.  The SNFServer must be configured to insert the headers
 into the email message.  The following headers are copied by the
 plugin into the message if SNFServer is configured to generate them:

  1) 'X-SPAM-MessageSniffer-Scan-Result' contains the body of the
  X-MessageSniffer-Scan-Result header inserted by SNFServer.

  2) 'X-SPAM-MessageSniffer-Rules' contains the body of the
  X-MessageSniffer-Rules header inserted by SNFServer.

  3) 'X-SPAM-GBUdb-Analysis' contains the body of the X-GBUdb-Analysis
  header inserted by SNFServer.

 Please see the INSTALL file for installation and configuration.

 SNF V2.x to V3.x Source Distribution Readme

 Version 3.x of SNF is a departure from previous versions of Message
 Sniffer on many levels. Though the core scanning engine and rulebase
 files are the same, the new version uses a client/server model.

 The client and server programs connect via TCP/Localhost port 9001.

 If this is your first experience with SNF in a *nix environment then
 please use the snfv2-3.5-PostfixExample as a guied.

 The new SNF engine and client are designed to work in parallel
 with prior versions of SNF so that it is easy to switch back if
 neede. In general all you need to do to switch between versions is
 to swap out the client executable in your scripts that scan messages
 with SNF. Be careful to read and understand your configuration!

 The SNFClient program is compatible with the old snf program when
 used as a scanner.

 The SNFServer program takes the place of a persistent instance of SNF
 and is required for the new version.

 The old program will generally ignore the new program and the new
 program will generally ignore the old program.

 The easiest way to convert a system from the previous (2-3) version
 of SNF to the new version is:

 * Copy the source distribution to it's own directory.

 * Run . compile in each of the client and source directories.

 * Copy the working files to your /var/spool/snfilter directory.

 cp SNF_Service/SNFServer.exe /var/spool/snfilter
 cp SNF_Client/SNFClient.exe /var/spool/snfilter
 cp identity.xml /var/spool/snfilter
 cp snf_engine.xml /var/spool/snfilter
 cp GBUdbIgnoreList.txt /var/spool/snfilter

 * Follow the SNFServer_readme.txt instructions and carefully
 configure your snf_engine.xml, identity.xml, and GBUdbIgnoreList.txt
 files.

 When you are ready to go, launch the SNFServer.exe program with
 the full path to the configuration file.

 /var/spool/snfilter/SNFServer.exe /var/spool/snfilter/snf_engine.xml

 If you run this from the console you will see a handy real-time
 monitor.

 To cleanly shut down the SNFServer use:

 SNFClient.exe -shutdown

 __________________________________________________________
 IF YOU ARE USING THE snfilter SCRIPT or something similar:

 * Modify your snfilter script to call the new SNFClient.exe

 SNIFFER_EXE=/var/spool/snfilter/SNFClient.exe

 * If your script is designed to inject headers then you could use
 the new xheader feature in the new engine. To do this:

 ** Comment out the section of your script which modifies the message.
 ** Turn on xheader injection in the snf_engine.xml file

  <xheaders>
  <!-- X-Header formatting and output options -->
      <output mode='inject'/>

 _________________________________________
 IF YOU ARE USING THE SpamAssassin Plugin:

 Adjust your snfilter.pm to point to the new SNFClient.exe 

 my $sniffer='SNFClient.exe';

 Note: The SNFClient.exe program will accept and ignore the
 authentication string so there is no reason to change your
 $key.

 # If you've gotten to this point then you have successfully installed
 # SNF on your server! The next set of instructions assumes you will
 # be using SNF with postfix and simply injecting headers that will be
 # used later to remove, quarantine, or otherwise redirect messages
 # detected as spam. There are as many ways to use SNF as there are
 # systems using it -- so the following is just a good starting place
 # for postfix users.

 # Be sure to restar SNFServer before trying to use it ;-)

 #------------------------------------------------------------------

 # Copy the snfscan-standalone script to sniffer and set the correct
 # access rights.

 cp snfscan-standalone sniffer
 chown snfilter sniffer
 chmod 570 sniffer

 # The snfscan-standalone version of the sniffer script creates a
 # temporary copy of the message, scans it with SNF, and then reinjects
 # the message. It is presumed that SNF is configured with x-header
 # injection turned on and that the x-headers have been customized
 # to suit your needs. Check the <xheaders/> section of your snf_engine.xml
 # file to verify that SNF is configured to do what you want.

 # Edit the sniffer shell script, and uncomment the action you want
 # the script to take. The default action will only to add a
 # "X-SortMonster-Msg-Sniffer-Match:" header to messages that
 # match the filter. This default action will not stop spam from
 # getting through.


 # Changes to /etc/postfix/master.cf
 # LEADING WHITE SPACES ARE IMPORTANT WHEN MAKING THIS CHANGE

 change:

 smtp      inet  n       -       n       -       -       smtpd

 to:

 smtp      inet  n       -       y       -       -       smtpd
     -o content_filter=snfilter


 also add:

 snfilter  unix  -       n       n       -       10      pipe
     flags=q user=snfilter argv=/var/spool/snfilter/sniffer
     -f ${sender} ${recipient}

 to master.cf


 # At this point You could just restart postfix, and hope nothing
 # goes wrong. Instead, it would be smarter to first test the
 # installation from the command line by injecting a message directly
 # into the filter script "sniffer".  We can issue a command like

 ./sniffer -f sender recipient <junkmsg.txt

 # Where junkmsg.txt is a spam test message. We should also test
 # a clean message to make sure that this script is working as we
 # expect it to.  In this case we would issue a command like

 ./sniffer -f sender recipient <cleanmsg.txt


 # If you've done everything correctly then all you have to do
 # is reload postfix to start the content_filter working.


 postfix reload


 # If something goes wrong you need only comment out, or remove
 # the line

     -o content_filter=snfilter

 # in /etc/postfix/master.cf, then reload postfix as shown above.
