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.

|
||||
|
||||
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 `bin/fail2ban-testcases`. It has
|
||||
options like --log-level that will probably be useful. Run
|
||||
`bin/fail2ban-testcases --help` for the full list of 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 bin/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.
|
||||
|
||||
pyflakes
|
||||
--------
|
||||
|
||||
pyflakes can be used to find unused imports, and unused, undefined and
|
||||
redefined variables. pyflakes should be run in any python code, including
|
||||
python based actions::
|
||||
|
||||
pyflakes bin/ config/ fail2ban/
|
||||
|
||||
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)::

||||
|
||||

|
||||
+ delegation

+ Jail (provided in __init__) which contains this Filter
|

Developing 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
|
||||

|
||||
|
||||
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.

=============================================================
|
||||
Fail2Ban (version 0.5.2) 2005/08/06
|
||||
=============================================================
|
||||
|
||||
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 is my first Python program. Moreover, English is not my
|
||||
mother tongue...
|
||||
|
||||
|
||||
More details:
|
||||
-------------
|
||||
|
||||
Fail2Ban is rather simple. I have a home server connected to
|
||||
the Internet which runs apache, samba, sshd, ... I see in my
|
||||
logs that people are trying to log into my box using "manual"
|
||||
brute force or scripts. They try 10, 20 and sometimes more
|
||||
user/password (without success anyway). In order to
|
||||
discourage these script kiddies, I wanted that sshd refuse
|
||||
login from a specific ip after 3 password failures. After
|
||||
some Google searches, I found that sshd was not able of that.
|
||||
So I search for a script or program that do it. I found
|
||||
nothing :-( So I decide to write mine and to learn Python :-)
|
||||
|
||||
For each sections defined in the configuration file, Fail2Ban
|
||||
tries to find lines which match the failregex. Then it
|
||||
retrieves the message time using timeregex and timepattern.
|
||||
It finally gets the ip and if it has already done 3 or more
|
||||
password failures in the last banTime, the ip is banned for
|
||||
banTime using a firewall rule. This rule is set by the user
|
||||
in the configuration file. Thus, Fail2Ban can be adapted for
|
||||
lots of firewall. After banTime, the rule is deleted. Notice
|
||||
that if no "plain" ip is available, Fail2Ban try to do DNS
|
||||
lookup in order to found one or several ip's to ban.
|
||||
|
||||
Sections can be freely added so it is possible to monitor
|
||||
several daemons at the same time.
|
||||
|
||||
Runs on my server and does its job rather well :-) The idea
|
||||
is to make fail2ban usable with daemons and services that
|
||||
require a login (sshd, telnetd, ...) and with different
|
||||
firewalls.
|
||||
|
||||
|
||||
Installation:
|
||||
-------------
|
||||
|
||||
Require: python-2.3 (http://www.python.org)
|
||||
|
||||
To install, just do:
|
||||
|
||||
> tar xvfj fail2ban-0.5.2.tar.bz2
|
||||
> cd fail2ban-0.5.2
|
||||
> python setup.py install
|
||||
|
||||
This will install Fail2Ban into /usr/lib/fail2ban. The fail2ban
|
||||
executable is placed into /usr/bin.
|
||||
|
||||
Gentoo: an ebuild is available on the website.
|
||||
Debian: a package is available on the website.
|
||||
|
||||
Fail2Ban should now be correctly installed. Just type:
|
||||
|
||||
> fail2ban -h
|
||||
|
||||
to see if everything is alright. You can configure fail2ban
|
||||
with a config file. Copy config/fail2ban.conf.default to
|
||||
/etc/fail2ban.conf.
|
||||
|
||||
You can use the initd script available in config/. Copy
|
||||
<dist>-initd to /etc/init.d/fail2ban. Gentoo users must copy
|
||||
gentoo-confd to /etc/conf.d/fail2ban. You can start fail2ban:
|
||||
|
||||
> /etc/init.d/fail2ban start
|
||||
|
||||
Gentoo users can add it to the default runlevel:
|
||||
|
||||
> rc-update add fail2ban default
|
||||
|
||||
Configuration:
|
||||
--------------
|
||||
|
||||
You can configure fail2ban using the file /etc/fail2ban.conf
|
||||
or using command line options. Command line options override
|
||||
the value stored in fail2ban.conf. Here are the command line
|
||||
options:
|
||||
|
||||
-b start in background
|
||||
-d start in debug mode
|
||||
-c <FILE> read configuration file FILE
|
||||
-p <FILE> create PID lock in FILE
|
||||
-h display this help message
|
||||
-i <IP(s)> IP(s) to ignore
|
||||
-k kill a currently running instance
|
||||
-r <VALUE> allow a max of VALUE password failure
|
||||
-t <TIME> ban IP for TIME seconds
|
||||
-v verbose. Use twice for greater effect
|
||||
-V print software version

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.
|
||||
|
||||
Fail2Ban is able to reduce the rate of incorrect authentications attempts
|
||||
however it cannot eliminate the risk that weak authentication presents.
|
||||
Configure services to use only two factor or public/private authentication
|
||||
mechanisms if you really want to protect services.
|
||||
|
||||
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:
|
||||
- [Python2 >= 2.6 or Python >= 3.2](http://www.python.org) or [PyPy](http://pypy.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)
|
||||
- [systemd >= 204](http://www.freedesktop.org/wiki/Software/systemd)
|
||||
|
||||
To install, just do:
|
||||
|
||||
tar xvfj fail2ban-0.9.0.tar.bz2
|
||||
cd fail2ban-0.9.0
|
||||
python setup.py install
|
||||
|
||||
This will install Fail2Ban into the python library directory. 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.
|
||||
|
||||
Configuration:
|
||||
--------------
|
||||
|
||||
You can configure Fail2Ban using the files in /etc/fail2ban. It is possible to
|
||||
configure the server using commands sent to it by fail2ban-client. The
|
||||
available commands are described in the fail2ban-client(1) manpage. Also see
|
||||
fail2ban(1) and jail.conf(5) manpages for further references.

||||
|
||||
* Only differences should be files that you don't want distributed.
|
||||
|
||||
|
||||
* Ensure the tests work from the tarball::
|
||||
|
||||
cd /tmp/fail2ban-0.9.0/ && export PYTHONPATH=`pwd` && bin/fail2ban-testcases
|
||||
|
||||
* Add/finalize the corresponding entry in the ChangeLog
|
||||
|
||||

|
||||
|
||||
* Ensure the top of the ChangeLog has the right version and current date.
|
||||
* Ensure the top entry of the ChangeLog has the right version and current date.

# Fail2Ban configuration file

# Submits attack reports to DShield (http://www.dshield.org/)
|
||||
#
|
||||
# You MUST configure at least:
|
||||
# <port> (the port that's being attacked - use number not name).
|
||||
#
|
||||
# You SHOULD also provide:
|
||||
# <myip> (your public IP address, if it's not the address of eth0)
|
||||
# <userid> (your DShield userID, if you have one - recommended, but reports will
|
||||
# be used anonymously if not)
|
||||
# <protocol> (the protocol in use - defaults to tcp)
|
||||
#
|
||||
# Best practice is to provide <port> and <protocol> in jail.conf like this:
|
||||
# action = dshield[port=1234,protocol=tcp]
|
||||
#
|
||||
# ...and create "dshield.local" with contents something like this:
|
||||
# [Init]
|
||||
# myip = 10.0.0.1
|
||||
# userid = 12345
|
||||
#
|
||||
# Other useful configuration values are <mailargs> (you can use for specifying
|
||||
# a different sender address for the report e-mails, which should match what is
|
||||
# configured at DShield), and <lines>/<minreportinterval>/<maxbufferage> (to
|

# configure how often the buffer is flushed).

# Fail2ban inserts blacklisted hosts into the f2b-<name> list

# own rules. The 3600 second timeout is independent and acts as a

# Fail2Ban action for sending xarf Login-Attack messages to IP owner
|
||||
#
|
||||
# IMPORTANT:
|
||||
#
|
||||
# Emailing a IP owner of abuse is a serious complain. Make sure that it is
|
||||
# serious. Fail2ban developers and network owners recommend you only use this
|
||||
# action for:
|
||||
# * The recidive where the IP has been banned multiple times
|
||||
# * Where maxretry has been set quite high, beyond the normal user typing
|
||||
# password incorrectly.
|
||||
# * For filters that have a low likelihood of receiving human errors
|
||||
#
|
||||
# DEPENDENCIES:
|
||||
#
|
||||
# This requires the dig command from bind-utils
|
||||
#
|
||||
# This uses the https://abusix.com/contactdb.html to lookup abuse contacts.
|
||||
#
|
||||
# XARF is a specification for sending a formatted response
|
||||
# for non-messaging based abuse including:
|
||||
#
|
||||
# Login-Attack, Malware-Attack, Fraud (Phishing, etc.), Info DNSBL
