-=============================================================
-
-ver. 0.7.5 (2006/12/07) - beta

-  option
-- Fixed Debian bug 400162. The "socket" option is now handled
-  correctly by fail2ban-client
-- Fixed RedHat init script. Thanks to Justin Shore

-  log reading and another for the actions
-- Execute several actions
-- Split configuration files. They are more readable and easy
-  to use
-- failregex uses group (<host>) now. This feature was already
-  present in the Debian package
-- lots of things...
-
-ver. 0.6.1 (2006/03/16) - stable

-  Thanks to Patrick B�rjesson
-- Removed 192.168.0.0/16 from ignoreip. Attacks could also
-  come from the local network.
-- Robust startup: if iptables module does not get fully
-  initialized after startup of fail2ban, fail2ban will do
-  "maxreinit" attempts to initialize its own firewall. It
-  will sleep between attempts for "polltime" number of
-  seconds (closes Debian: #334272). Thanks to Yaroslav
-  Halchenko
-- Added "interpolations" in fail2ban.conf. This is provided
-  by the ConfigParser module. Old configuration files still
-  work. Thanks to Yaroslav Halchenko

-    after background and then only loglevel (verbose, debug)
-    is processed, so the warning could be seen in the logs
-  * Added a keyword <section> in parsing of the subject and
-    the body of an email sent out by fail2ban (closes:
-    #330311)
-
-ver. 0.5.4 (2005/09/13) - beta
-----------

+The following copyright applies to all files present in the Fail2ban package,
+except if a different copyright is explicitly defined in this file.
+
+
+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  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
+this service 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 make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  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.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the 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 a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE 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.
+
+		     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
+convey 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 2 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, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This 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.

+================================================================================
+How to develop for Fail2Ban
+================================================================================
+
+Fail2Ban uses GIT (http://git-scm.com/) distributed source control. This gives
+each developer their own complete copy of the entire repository. Developers can
+add and switch branches and commit changes when ever they want and then ask a
+maintainer to merge their changes.
+
+Fail2Ban uses GitHub (https://github.com/fail2ban/fail2ban) to manage access to
+the Git repository. GitHub provides free hosting for open-source projects as
+well as a web-based Git repository browser and an issue tracker.
+
+If you are familiar with Python and you have a bug fix or a feature that you
+would like to add to Fail2Ban, the best way to do so it to use the GitHub Pull
+Request feature. You can find more details on the Fail2Ban wiki
+(http://www.fail2ban.org/wiki/index.php/Get_Involved)
+
+Pull Requests
+=============
+
+When submitting pull requests on GitHub we ask you to:
+* Clearly describe the problem you're solving;
+* Don't introduce regressions that will make it hard for systems administrators
+  to update;
+* If adding a major feature rebase your changes on master and get to a single commit;
+* Include test cases (see below);
+* Include sample logs (if relevant);
+* Include a change to the relevant section of the ChangeLog; and
+* Include yourself in THANKS if not already there.
+
+If you are developing filters see the FILTERS file for documentation.
+
+Code Testing
+============
+
+Existing tests can be run by executing `fail2ban-testcases`. This has options
+like --log-level that will probably be useful. `fail2ban-testcases --help` for
+full options.
+
+Test cases should cover all usual cases, all exception cases and all inside
+/ outside boundary conditions.
+
+Test cases should cover all branches. The coverage tool will help identify
+missing branches. Also see http://nedbatchelder.com/code/coverage/branch.html
+for more details.
+
+Install the package python-coverage to visualise your test coverage. Run the
+following (note: on Debian-based systems, the script is called
+`python-coverage`):
+
+coverage run fail2ban-testcases
+coverage html
+
+Then look at htmlcov/index.html and see how much coverage your test cases
+exert over the code base. Full coverage is a good thing however it may not be
+complete. Try to ensure tests cover as many independent paths through the
+code.
+
+Manual Execution. To run in a development environment do:
+
+./fail2ban-client -c config/ -s /tmp/f2b.sock -i start
+
+some quick commands:
+
+status
+add test pyinotify
+status test
+set test addaction iptables
+set test actionban iptables echo <ip> <cidr> >> /tmp/ban
+set test actionunban iptables echo <ip> <cidr> >> /tmp/unban
+get test actionban iptables
+get test actionunban iptables
+set test banip 192.168.2.2
+status test
+
+
+
+Coding Standards
+================
+
+Style
+-----
+
+Please use tabs for now. Keep to 80 columns, at least for readable text.
+
+Tests
+-----
+
+Add tests. They should test all the code you add in a meaning way.
+
+Coverage
+--------
+
+Test coverage should always increase as you add code.
+
+You may use "# pragma: no cover" in the code for branches of code that support
+older versions on python. For all other uses of "pragma: no cover" or
+"pragma: no branch" document the reason why its not covered. "I haven't written
+a test case" isn't a sufficient reason.
+
+Documentation
+-------------
+
+Ensure this documentation is up to date after changes. Also ensure that the man
+pages still are accurate. Ensure that there is sufficient documentation for
+your new features to be used.
+
+Bugs
+----
+
+Remove them and don't add any more.
+
+Git
+---
+
+Use the following tags in your commit messages:
+
+'BF:' for bug fixes
+'DOC:' for documentation fixes
+'ENH:' for enhancements
+'TST:' for commits concerning tests only (thus not touching the main code-base)
+
+Multiple tags could be joined with +, e.g. "BF+TST:".
+
+Use the text "closes #333"/"resolves #333 "/"fixes #333" where 333 represents
+an issue that is closed. Other text and details in link below.
+See: https://help.github.com/articles/closing-issues-via-commit-messages
+
+If merge resulted in conflicts, clarify what changes were done to
+corresponding files in the 'Conflicts:' section of the merge commit
+message.  See e.g. https://github.com/fail2ban/fail2ban/commit/f5a8a8ac
+
+Adding Actions
+--------------
+
+If you add an action.d/*.conf file also add a example in config/jail.conf
+with enabled=false and maxretry=5 for ssh.
+
+
+Design
+======
+
+Fail2Ban was initially developed with Python 2.3 (IIRC). It should
+still be compatible with Python 2.4 and such compatibility assurance
+makes code ... old-fashioned in many places (RF-Note).  In 0.7 the
+design went through major re-factoring into client/server,
+a-thread-per-jail design which made it a bit difficult to follow.
+Below you can find a sketchy description of the main components of the
+system to orient yourself better.
+
+server/
+------
+
+Core classes hierarchy (feel welcome to draw a better/more complete
+one)::
+
+ ->   inheritance
+ +    delegation
+ *    storage of multiple instances
+
+ RF-Note   just a note which might be useful to address while doing RF
+
+ JailThread -> Filter -> FileFilter -> {FilterPoll, FilterPyinotify, ...}
+               |         * FileContainer
+               + FailManager
+               + DateDetector
+			   + Jail (provided in __init__) which contains this Filter
+                 (used for passing tickets from FailManager to Jail's __queue)
+ Server
+   + Jails
+      * Jail
+        + Filter  (in __filter)
+        * tickets (in __queue)
+        + Actions (in __action)
+          * Action
+          + BanManager
+
+
+failmanager.py
+~~~~~~~~~~~~~~
+
+FailManager
+
+  Keeps track of failures, recorded as 'tickets'.  All operations are
+  done via acquiring a lock
+
+FailManagerEmpty(Exception)
+
+  raised by FailManager.toBan after reaching the list of tickets
+  (RF-Note: asks to become a generator ;) )
+
+
+filter.py
+~~~~~~~~~~
+
+Filter(JailThread)
+
+  Wraps (non-threaded) FailManager (and proxies to it quite a bit),
+  and provides all primary logic for processing new lines, what IPs to
+  ignore, etc
+
+  .failManager  [FailManager]
+  .dateDetector [DateDetector]
+  .__failRegex  [list]
+  .__ignoreRegex [list]
+    Contains regular expressions for failures and ignores
+  .__findTime   [numeric]
+    Used in `processLineAndAdd` to skip old lines
+
+FileFilter(Filter):
+
+  Files-aware Filter
+
+  .__logPath [list]
+    keeps the tracked files (added 1-by-1 using addLogPath)
+    stored as FileContainer's
+  .getFailures
+    actually just returns
+    True
+      if managed to open and get lines (until empty)
+    False
+      if failed to open or absent container matching the filename
+
+FileContainer
+
+  Adapter for a file to deal with log rotation.
+
+  .open,.close,.readline
+     RF-Note: readline returns "" with handler absent... shouldn't it be None?
+  .__pos
+    Keeps the position pointer
+
+
+dnsutils.py
+~~~~~~~~~~~
+
+DNSUtils
+
+  Utility class for DNS and IP handling
+
+
+filter*.py
+~~~~~~~~~~
+
+Implementations of FileFilter's for specific backends.  Derived
+classes should provide an implementation of `run` and usually
+override `addLogPath`, `delLogPath` methods.  In run() method they all
+one way or another provide
+
+		try:
+			while True:
+				ticket = self.failManager.toBan()
+				self.jail.putFailTicket(ticket)
+		except FailManagerEmpty:
+			self.failManager.cleanup(MyTime.time())
+
+thus channelling "ban tickets" from their failManager to the
+corresponding jail.
+
+action.py
+~~~~~~~~~
+
+Takes care about executing start/check/ban/unban/stop commands

+================================================================================
+Developing Filters
+================================================================================
+
+Filters
+=======
+
+Filters are tricky. They need to:
+* work with a variety of the versions of the software that generates the logs;
+* work with the range of logging configuration options available in the
+  software;
+* work with multiple operating systems;
+* not make assumptions about the log format in excess of the software
+  (e.g. do not assume a username doesn't contain spaces and use \S+ unless
+  you've checked the source code);
+* account for how future versions of the software will log messages
+  (e.g. guess what would happen to the log message if different authentication
+  types are added);
+* not be susceptible to DoS vulnerabilities (see Filter Security below); and
+* match intended log lines only.
+
+Please follow the steps from Filter Test Cases to Developing Filter Regular
+Expressions and submit a GitHub pull request (PR) afterwards. If you get stuck,
+you can push your unfinished changes and still submit a PR -- describe
+what you have done, what is the hurdle, and we'll attempt to help (PR
+will be automagically updated with future commits you would push to
+complete it).
+
+Filter test cases
+-----------------
+
+Purpose:
+
+Start by finding the log messages that the application generates related to
+some form of authentication failure. If you are adding to an existing filter
+think about whether the log messages are of a similar importance and purpose
+to the existing filter. If you were a user of Fail2Ban, and did a package
+update of Fail2Ban that started matching new log messages, would anything
+unexpected happen?  Would the bantime/findtime for the jail be appropriate for
+the new log messages?  If it doesn't, perhaps it needs to be in a separate
+filter definition, for example like exim filter aims at authentication failures
+and exim-spam at log messages related to spam.
+
+Even if it is a new filter you may consider separating the log messages into
+different filters based on purpose.
+
+Cause:
+
+Are some of the log lines a result of the same action? For example, is a PAM
+failure log message, followed by an application specific failure message the
+result of the same user/script action?  If you add regular expressions for
+both you would end up with two failures for a single action.
+Therefore, select the most appropriate log message and document the other log
+message) with a test case not to match it and a description as to why you chose
+one over another.
+
+With the selected log lines consider what action has caused those log
+messages and whether they could have been generated by accident? Could
+the log message be occurring due to the first step towards the application
+asking for authentication? Could the log messages occur often? If some of
+these are true make a note of this in the jail.conf example that you provide.
+
+Samples:
+
+It is important to include log file samples so any future change in the regular
+expression will still work with the log lines you have identified.
+
+The sample log messages are provided in a file under testcases/files/logs/
+named identically as the corresponding filter (but without .conf extension).
+Each log line should be preceded by a line with failJSON metadata (so the logs
+lines are tested in the test suite) directly above the log line. If there is
+any specific information about the log message, such as version or an
+application configuration option that is needed for the message to occur,
+include this in a comment (line beginning with #) above the failJSON metadata.
+
+Log samples should include only one, definitely not more than 3, examples of
+log messages of the same form. If log messages are different in different
+versions of the application log messages that show this are encouraged.
+
+Also attempt to inject an IP into the application (e.g. by specifying
+it as a username) so that Fail2Ban possibly detects the IP
+from user input rather than the true origin. See the Filter Security section
+and the top example in testcases/files/logs/apache-auth as to how to do this.
+One you have discovered that this is possible, correct the regex so it doesn't
+match and provide this as a test case with "match": false (see failJSON below).
+
+If the mechanism to create the log message isn't obvious provide a
+configuration and/or sample scripts testcases/files/config/{filtername} and
+reference these in the comments above the log line.
+
+FailJSON metadata:
+
+A failJSON metadata is a comment immediately above the log message. It will
+look like:
+
+# failJSON: { "time": "2013-06-10T10:10:59", "match": true , "host": "93.184.216.119" }
+
+Time should match the time of the log message. It is in a specific format of
+Year-Month-Day'T'Hour:minute:Second.  If your log message does not include a
+year, like the example below, the year should be listed as 2005, if before Sun
+Aug 14 10am UTC, and 2004 if afterwards.  Here is an example failJSON
+line preceding a sample log line:
+
+# failJSON: { "time": "2005-03-24T15:25:51", "match": true , "host": "198.51.100.87" }
+Mar 24 15:25:51 buffalo1 dropbear[4092]: bad password attempt for 'root' from 198.51.100.87:5543
+
+The "host" in failJSON should contain the IP or domain that should be blocked.
+
+For long lines that you do not want to be matched (e.g. from log injection
+attacks) and any log lines to be excluded (see "Cause" section above), set
+"match": false in the failJSON and describe the reason in the comment above.
+
+After developing regexes, the following command will test all failJSON metadata
+against the log lines in all sample log files
+
+./fail2ban-testcases testSampleRegex
+
+Developing Filter Regular Expressions
+-------------------------------------
+
+Date/Time:
+
+At the moment, Fail2Ban depends on log lines to have time stamps.  That is why
+before starting to develop failregex, check if your log line format known to
+Fail2Ban.  Copy the time component from the log line and append an IP address to
+test with following command:
+
+./fail2ban-regex "2013-09-19 02:46:12 1.2.3.4" "<HOST>"
+
+Output of such command should contain something like:
+
+Date template hits:
+|- [# of hits] date format
+|  [1] Year-Month-Day Hour:Minute:Second
+
+Ensure that the template description matches time/date elements in your log line
+time stamp.  If there is no matched format then date template needs to be added
+to server/datedetector.py.  Ensure that a new template is added in the order
+that more specific matches occur first and that there is no confusion between a
+Day and a Month.
+
+Filter file:
+
+The filter is specified in a config/filter.d/{filtername}.conf file. Filter file
+can have sections INCLUDES (optional) and Definition as follows:
+
+[INCLUDES]
+
+before = common.conf
+
+after = filtername.local
+
+[Definition]
+
+failregex = ....
+
+ignoreregex = ....
+
+This is also documented in the man page jail.conf (section 5). Other definitions
+can be added to make failregex's more readable and maintainable to be used
+through string Interpolations (see http://docs.python.org/2.7/library/configparser.html)
+
+
+General rules:
+
+Use "before" if you need to include a common set of rules, like syslog or if
+there is a common set of regexes for multiple filters.
+
+Use "after" if you wish to allow the user to overwrite a set of customisations
+of the current filter. This file doesn't need to exist.
+
+Try to avoid using ignoreregex mainly for performance reasons. The case when you
+would use it is if in trying to avoid using it, you end up with an unreadable
+failregex.
+
+Syslog:
+
+If your application logs to syslog you can take advantage of log line prefix
+definitions present in common.conf.  So as a base use:
+
+[INCLUDES]
+
+before = common.conf
+
+[Definition]
+
+_daemon = app
+
+failregex = ^%(__prefix_line)s
+
+In this example common.conf defines __prefix_line which also contains the
+_daemon name (in syslog terms the service) you have just specified. _daemon
+can also be a regex.
+
+For example, to capture following line _daemon should be set to "dovecot"
+
+Dec 12 11:19:11 dunnart dovecot: pop3-login: Aborted login (tried to use disabled plaintext auth): rip=190.210.136.21, lip=113.212.99.193
+
+and then ^%(__prefix_line)s would match "Dec 12 11:19:11 dunnart dovecot:
+". Note it matches the trailing space(s) as well.
+
+Substitutions (AKA string interpolations):
+
+We have used string interpolations in above examples.  They are useful for
+making the regexes more readable, reuse generic patterns in multiple failregex
+lines, and also to refer definition of regex parts to specific filters or even
+to the user.  General principle is that value of a _name variable replaces
+occurrences of %(_name)s within the same section or anywhere in the config file
+if defined in [DEFAULT] section.
+
+Regular Expressions:
+
+Regular expressions (failregex, ignoreregex) assume that the date/time has been
+removed from the log line (this is just how fail2ban works internally ATM).
+
+If the format is like '<date...> error 1.2.3.4 is evil' then you need to match
+the < at the start so regex should be similar to '^<> <HOST> is evil$' using
+<HOST> where the IP/domain name appears in the log line.
+
+The following general rules apply to regular expressions:
+
+* ensure regexes start with a ^ and are as restrictive as possible. E.g. do not
+  use .* if \d+ is sufficient;
+* use functionality of Python regexes defined in the standard Python re library
+  http://docs.python.org/2/library/re.html;
+* make regular expressions readable (as much as possible). E.g.
+  (?:...) represents a non-capturing regex but (...) is more readable, thus
+  preferred.
+
+If you have only a basic knowledge of regular repressions we advise to read
+http://docs.python.org/2/library/re.html first.  It doesn't take long and would
+remind you e.g. which characters you need to escape and which you don't.
+
+Developing/testing a regex:
+
+You can develop a regex in a file or using command line depending on your
+preference. You can also use samples you have already created in the test cases
+or test them one at a time.
+
+The general tool for testing Fail2Ban regexes is fail2ban-regex. To see how to
+use it run:
+
+./fail2ban-regex --help
+
+Take note of  -l heavydebug  / -l debug  and -v as they might be very useful.
+
+TIP: Take a look at the source code of the application you are developing
+     failregex for. You may see optional or extra log messages, or parts there
+     of, that need to form part of your regex.  It may also reveal how some
+     parts are constrained and different formats depending on configuration or
+     less common usages.
+
+TIP: For looking through source code - http://sourcecodebrowser.com/ . It has
+     call graphs and can browse different versions.
+
+TIP: Some applications log spaces at the end. If you are not sure add \s*$ as
+     the end part of the regex.
+
+If your regex is not matching, http://www.debuggex.com/?flavor=python can help
+to tune it.  fail2ban-regex -D ...  will present Debuggex URLs for the regexs
+and sample log files that you pass into it.
+
+In general use when using regex debuggers for generating fail2ban filters:
+* use regex from the ./fail2ban-regex output (to ensure all substitutions are
+done)
+* replace <HOST> with (?&.ipv4)
+* make sure that regex type set to Python
+* for the test data put your log output with the date/time removed
+
+When you have fixed the regex put it back into your filter file.
+
+Please spread the good word about Debuggex - Serge Toarca is kindly continuing
+its free availability to Open Source developers.
+
+Finishing up:
+
+If you've added a new filter, add a new entry in config/jail.conf. The theory
+here is that a user will create a jail.local with [filtername]\nenable=true to
+enable your jail.
+
+So more specifically in the [filter] section in jail.conf:
+* ensure that you have "enabled = false" (users will enable as needed);
+* use "filter =" set to your filter name;
+* use a typical action to disable ports associated with the application;
+* set "logpath" to the usual location of application log file;
+* if the default findtime or bantime isn't appropriate to the filter, specify
+  more appropriate choices (possibly with a brief comment line).

+
+Filter Security
+---------------
+
+Poor filter regular expressions are susceptible to DoS attacks.
+
+When a remote user has the ability to introduce text that would match filter's
+failregex, while matching inserted text to the <HOST> part, they have the
+ability to deny any host they choose.
+
+So the <HOST> part must be anchored on text generated by the application, and
+not the user, to an extent sufficient to prevent user inserting the entire text
+matching this or any other failregex.
+
+Ideally filter regex should anchor at the beginning and at the end of log line.
+However as more applications log at the beginning than the end, anchoring the
+beginning is more important. If the log file used by the application is shared
+with other applications, like system logs, ensure the other application that use
+that log file do not log user generated text at the beginning of the line, or,
+if they do, ensure the regexes of the filter are sufficient to mitigate the risk
+of insertion.
+
+
+Examples of poor filters
+------------------------
+
+1. Too restrictive
+
+We find a log message:
+
+    Apr-07-13 07:08:36 Invalid command fial2ban from 1.2.3.4
+
+We make a failregex
+
+    ^Invalid command \S+ from <HOST>
+
+Now think evil. The user does the command 'blah from 1.2.3.44'
+
+The program diligently logs:
+
+    Apr-07-13 07:08:36 Invalid command blah from 1.2.3.44 from 1.2.3.4
+
+And fail2ban matches 1.2.3.44 as the IP that it ban. A DoS attack was successful.
+
+The fix here is that the command can be anything so .* is appropriate.
+
+    ^Invalid command .* from <HOST>
+
+Here the .* will match until the end of the string. Then realise it has more to
+match, i.e. "from <HOST>" and go back until it find this. Then it will ban
+1.2.3.4 correctly. Since the <HOST> is always at the end, end the regex with a $.
+
+    ^Invalid command .* from <HOST>$
+
+Note if we'd just had the expression:
+
+    ^Invalid command \S+ from <HOST>$
+
+Then provided the user put a space in their command they would have never been
+banned.
+
+2. Unanchored regex can match other user injected data
+
+From the Apache vulnerability CVE-2013-2178
+( original ref: https://vndh.net/note:fail2ban-089-denial-service ).
+
+An example bad regex for Apache:
+
+    failregex = [[]client <HOST>[]] user .* not found
+
+Since the user can do a get request on:
+
+    GET /[client%20192.168.0.1]%20user%20root%20not%20found HTTP/1.0
+Host: remote.site
+
+Now the log line will be:
+
+    [Sat Jun 01 02:17:42 2013] [error] [client 192.168.33.1] File does not exist: /srv/http/site/[client 192.168.0.1] user root not found
+
+As this log line doesn't match other expressions hence it matches the above
+regex and blocks 192.168.33.1 as a denial of service from the HTTP requester.
+
+3.  Over greedy pattern matching
+
+From: https://github.com/fail2ban/fail2ban/pull/426
+
+An example ssh log (simplified)
+
+    Sep 29 17:15:02 spaceman sshd[12946]: Failed password for user from 127.0.0.1 port 20000 ssh1: ruser remoteuser
+
+As we assume username can include anything including spaces its prudent to put
+.* here. The remote user can also exist as anything so lets not make assumptions again.
+
+    failregex = ^%(__prefix_line)sFailed \S+ for .* from <HOST>( port \d*)?( ssh\d+)?(: ruser .*)?$
+
+So this works. The problem is if the .* after remote user is injected by the
+user to be 'from 1.2.3.4'. The resultant log line is.
+
+    Sep 29 17:15:02 spaceman sshd[12946]: Failed password for user from 127.0.0.1 port 20000 ssh1: ruser from 1.2.3.4
+
+Testing with:
+
+    fail2ban-regex -v 'Sep 29 17:15:02 Failed password for user from 127.0.0.1 port 20000 ssh1: ruser from 1.2.3.4' '^ Failed \S+ for .* from <HOST>( port \d*)?( ssh\d+)?(: ruser .*)?$'
+
+TIP: I've removed the bit that matches __prefix_line from the regex and log.
+
+Shows:
+
+    1) [1] ^ Failed \S+ for .* from <HOST>( port \d*)?( ssh\d+)?(: ruser .*)?$
+       1.2.3.4  Sun Sep 29 17:15:02 2013
+
+It should of matched 127.0.0.1. So the first greedy part of the greedy regex
+matched until the end of the string. The was no "from <HOST>" so the regex
+engine worked backwards from the end of the string until this was matched.
+
+The result was that 1.2.3.4 was matched, injected by the user, and the wrong IP
+was banned.
+
+The solution here is to make the first .* non-greedy with .*?. Here it matches
+as little as required and the fail2ban-regex tool shows the output:
+
+    fail2ban-regex -v 'Sep 29 17:15:02 Failed password for user from 127.0.0.1 port 20000 ssh1: ruser from 1.2.3.4' '^ Failed \S+ for .*? from <HOST>( port \d*)?( ssh\d+)?(: ruser .*)?$'
+
+    1) [1] ^ Failed \S+ for .*? from <HOST>( port \d*)?( ssh\d+)?(: ruser .*)?$
+       127.0.0.1  Sun Sep 29 17:15:02 2013
+
+So the general case here is a log line that contains:
+
+    (fixed_data_1)<HOST>(fixed_data_2)(user_injectable_data)
+
+Where the regex that matches fixed_data_1 is gready and matches the entire
+string, before moving backwards and user_injectable_data can match the entire
+string.
+
+Another case:
+
+ref: https://www.debuggex.com/r/CtAbeKMa2sDBEfA2/0
+
+A webserver logs the following without URL escaping:
+
+    [error] 2865#0: *66647 user "xyz" was not found in "/file", client: 1.2.3.1, server: www.host.com, request: "GET ", client: 3.2.1.1, server: fake.com, request: "GET exploited HTTP/3.3", host: "injected.host", host: "www.myhost.com"
+
+regex:
+
+    failregex = ^ \[error\] \d+#\d+: \*\d+ user "\S+":? (?:password mismatch|was not found in ".*"), client: <HOST>, server: \S+, request: "\S+ .+ HTTP/\d+\.\d+", host: "\S+"
+
+The .* matches to the end of the string. Finds that it can't continue to match
+", client ... so it moves from the back and find that the user injected web URL:
+
+    ", client: 3.2.1.1, server: fake.com, request: "GET exploited HTTP/3.3", host: "injected.host
+
+In this case there is a fixed host: "www.myhost.com" at the end so the solution
+is to anchor the regex at the end with a $.
+
+If this wasn't the case then first .* needed to be made so it didn't capture
+beyond <HOST>.
+
+4. Application generates two identical log messages with different meanings
+
+If the application generates the following two messages under different
+circumstances:
+
+    client <IP>: authentication failed
+    client <USER>: authentication failed
+
+
+Then it's obvious that a regex of "^client <HOST>: authentication
+failed$" will still cause problems if the user can trigger the second
+log message with a <USER> of 123.1.1.1.
+
+Here there's nothing to do except request/change the application so it logs
+messages differently.

+README FOR SOLARIS INSTALLATIONS
+
+By Roy Sigurd Karlsbakk <roy@karlsbakk.net>
+
+ABOUT
+
+This README is meant for those wanting to install fail2ban on Solaris 10,
+OpenSolaris, OpenIndiana etc. To some degree it may as well be useful for
+users of older Solaris versions and Nexenta, but don't rely on it.
+
+READ ME FIRST
+
+If I use the term Solaris, I am talking about any Solaris dialect, that is, the
+official Sun/Oracle ones or derivatives. If I describe an OS as
+"OpenSolaris-based", it means it's either OpenSolaris, OpenIndiana or one of the
+other, but /not/ the Nexenta family, since this only uses the OpenSolaris/
+IllumOS kernel and not the userland. If I say Solaris 10, I mean Solaris 10 and
+perhaps, if you're lucky and have some good gods on your side, it may also apply
+to Solaris 9 or even 8 and hopefully in the new Solaris 11 whenever that may be
+released. Quoted lines of code, settings etc. are indented with two spaces.
+This does _not_ mean you should use that indentation, especially in config files
+where they can be harmful. Optional settings are prefixed with OPT: while
+required settings are prefixed with REQ:. If no prefix is found, regard it as a
+required setting.
+
+INSTALLATION ON SOLARIS
+
+The installation is straight forward on Solaris as well as on linux/bsd/etc.
+./setup.py install installs the general packages in /usr/bin on OpenSolaris-
+based distros or (at least on this box) under /usr/sfw/bin on Solaris 10. In
+the files/ directory you will find the file solaris-fail2ban.xml containing the
+Solaris service. To install this, run the following command as root (or with
+sudo):
+
+  svccfg import files/solaris-fail2ban.xml
+
+This should normally without giving an error. If you get an error, deal with it,
+and please post any relevant info (or fixes?) to the fail2ban mailing list.
+Next install the service handler - copy the script in and allow it to be executed:
+
+  cp files/solaris-svc-fail2ban /lib/svc/method/svc-fail2ban
+  chmod +x /lib/svc/method/svc-fail2ban
+
+CONFIGURE SYSLOG
+
+For some reason, a default Solaris installation does not log ssh login attempts,
+and since fail2ban works by monitoring logs, enabling this logging is rather
+important for it to work. To enable this, edit /etc/syslog.conf and add a line
+at the end:
+
+  auth.info					/var/adm/auth.log
+
+Save the file and exit, and run
+
+  touch /var/adm/auth.log
+
+The Solaris system logger will _not_ create a non-existing file. Now, restart
+the system logger.
+
+  svcadm restart system-log
+
+Try to ssh into localhost with ssh asdf@localhost and enter an invalid password.
+Make sure this is logged in the above file. When done, you may configure
+fail2ban.
+
+FAIL2BAN CONFIGURATION
+
+OPT: Create /etc/fail2ban/fail2ban.local containing:
+
+# Fail2Ban configuration file for logging fail2ban on Solaris
+#
+[Definition]
+
+logtarget = /var/adm/fail2ban.log
+
+
+REQ: Create /etc/fail2ban/jail.local containing:
+
+[ssh-tcpwrapper]
+
+enabled     = true
+filter      = sshd
+action      = hostsdeny[daemon_list=sshd]
+              sendmail-whois[name=SSH, dest=you@example.com]
+ignoreregex = for myuser from
+logpath     = /var/adm/auth.log
+
+Set the sendmail dest address to something useful or drop the line to stop it spamming you.
+Set 'myuser' to your username to avoid banning yourself or remove the line.
+
+START (OR RESTART) FAIL2BAN
+
+Enable the fail2ban service with
+
+  svcadm enable fail2ban
+
+When done, check that all services are running well
+
+  svcs -xv
+
+GOTCHAS AND FIXMES
+
+* It seems the installation may be starting fail2ban automatically. If this is
+  done, fail2ban will not start, but no errors will be returned from svcs
+  (above). Check if it's running with 'ps -ef | grep fail2ban' and manually kill
+  the PID if it is. Re-enable fail2ban and try again
+
+    svcadm disable fail2ban
+    svcadm enable fail2ban
+
+* If svcs -xv says that fail2ban failed to start or svcs says it's in maintenance mode
+  check /var/svc/log/network-fail2ban:default.log for clues.
+  Check permissions on /var/adm, /var/adm/auth.log /var/adm/fail2ban.log and /var/run/fail2ban
+  You may need to:
+
+  sudo mkdir /var/run/fail2ban
+
+* Fail2ban adds lines like these to /etc/hosts.deny:
+
+    sshd: 1.2.3.4

+## Fail2Ban: ban hosts that cause multiple authentication errors
+
+Fail2Ban scans log files like /var/log/pwdfail and bans IP that makes too many
+password failures. It updates firewall rules to reject the IP address. These
+rules can be defined by the user. Fail2Ban can read multiple log files such as
+sshd or Apache web server ones.
+
+This README is a quick introduction to Fail2ban. More documentation, FAQ, HOWTOs
+are available in fail2ban(1) manpage and on the website http://www.fail2ban.org
+
+Installation:
+-------------
+
+**It is possible that Fail2ban is already packaged for your distribution.  In
+this case, you should use it instead.**
+
+Required:
+- [Python >= 2.4](http://www.python.org)
+
+Optional:
+- [pyinotify >= 0.8.3](https://github.com/seb-m/pyinotify)
+  - Linux >= 2.6.13
+- [gamin >= 0.0.21](http://www.gnome.org/~veillard/gamin)
+
+To install, just do:
+
+    tar xvfj fail2ban-0.8.14.tar.bz2
+    cd fail2ban-0.8.14
+    python setup.py install
+
+This will install Fail2Ban into /usr/share/fail2ban. The executable scripts are
+placed into /usr/bin, and configuration under /etc/fail2ban.
+
+Fail2Ban should be correctly installed now. Just type:
+
+    fail2ban-client -h
+
+to see if everything is alright. You should always use fail2ban-client and
+never call fail2ban-server directly.

+	Class adds functionality to SafeConfigParser to handle included

+
+	File should have section [includes] and only 2 options implemented
+	are 'files_before' and 'files_after' where files are listed 1 per
+	line.
+
+	Example:
+
+[INCLUDES]
+before = 1.conf
+         3.conf
+
+after = 1.conf
+
+	It is a simple implementation, so just basic care is taken about
+	recursion. Includes preserve right order, ie new files are
+	inserted to the list of read configs before original, and their
+	includes correspondingly so the list should follow the leaves of
+	the tree.
+
+	I wasn't sure what would be the right way to implement generic (aka c++

+# Reporting an IP of abuse is a serious complaint. Make sure that it is
+# serious. Fail2ban developers and network owners recommend you only use this

+# Submits attack reports to myNetWatchman (http://www.mynetwatchman.com/)
+#
+# You MUST configure at least:
+# <port> (the port that's being attacked - use number not name).
+# <mnwlogin> (your mNW login).
+# <mnwpass> (your mNW password).
+#
+# You SHOULD also provide:
+# <myip> (your public IP address, if it's not the address of eth0)
+# <protocol> (the protocol in use - defaults to tcp)
+#
+# Best practice is to provide <port> and <protocol> in jail.conf like this:
+# action = mynetwatchman[port=1234,protocol=udp]
+#
+# ...and create "mynetwatchman.local" with contents something like this:
+# [Init]
+# mnwlogin = me@example.com
+# mnwpass = SECRET
+# myip = 10.0.0.1
+#

+# The default Shorewall configuration is with "BLACKLISTNEWONLY=Yes" (see
+# file /etc/shorewall/shorewall.conf). This means that when Fail2ban adds a
+# new shorewall rule to ban an IP address, that rule will affect only new
+# connections. So if the attempter goes on trying using the same connection
+# he could even log in. In order to get the same behavior of the iptable
+# action (so that the ban is immediate) the /etc/shorewall/shorewall.conf
+# file should me modified with "BLACKLISTNEWONLY=No". Note that as of
+# Shorewall 4.5.13 BLACKLISTNEWONLY is deprecated; however the equivalent
