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.

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

Fail2Ban (version 0.8.6) 2011/11/28
================================================================================
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 on the project website: http://www.fail2ban.org
Installation:
-------------
Required:
>=python-2.3 (http://www.python.org)
Optional:
pyinotify:
>=linux-2.6.13
>=python-2.4
>=pyinotify-0.8.3 (https://github.com/seb-m/pyinotify)
Gamin:
>=gamin-0.0.21 (http://www.gnome.org/~veillard/gamin)
To install, just do:
> tar xvfj fail2ban-0.8.6.tar.bz2
> cd fail2ban-0.8.6
> python setup.py install
This will install Fail2Ban into /usr/share/fail2ban. The executable scripts are
placed into /usr/bin.
It is possible that Fail2ban is already packaged for your distribution. In this
case, you should use it.
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 man page of fail2ban-client. Please refer to it or
to the website: http://www.fail2ban.org

================================================================================
ToDo
================================================================================
Legend:
- not yet done
? maybe
# partially done
* done
- Removed relative imports
- Cleanup fail2ban-client and fail2ban-server. Move code to server/ and client/
- Add timeout to external commands (signal alarm, watchdog thread, etc)
- Uniformize filters and actions name. Use the software name (openssh, postfix,
proftp) and possible qualifier (e.g. auth) after a '-'
- Added <USER> tag for failregex. Add features using this information. Maybe add
more tags
- Look at the memory consumption. Decrease memory usage
- More detailed statistics
- Auto-enable function (search for log files), check modification date to see if
service is still in use
- Improve parsing of the action parameters in jailreader.py
- Better handling of the protocol in transmitter.py
- Add gettext support (I18N)
- Multiline log reading
- Improve execution of action. Why does subprocess.call deadlock with
multi-jails?
# see Feature Request Tracking System at SourceForge.net
# improve documentation and website for user
# better return values in function
# refactoring in server.py, actions.py, filter.py

Class adds functionality to SafeConfigParser to handle included
other configuration files (or may be urls, whatever in the future)
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++
template) so we could base at any *configparser class... so I will
leave it for the future

# 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).

# Changing iptables rules requires root priviledges. If fail2ban is
# configured to run as root, firewall setup can be performed by
# fail2ban automatically. However, if fail2ban is configured to run as
# a normal user, the configuration must be done by some other means
# (e.g. using static firewall configuration with the
# iptables-persistent package).
#
# Explanation of the rule below:
# Check if any packets coming from an IP on the fail2ban-<name>
# list have been seen in the last 3600 seconds. If yes, update the
# timestamp for this IP and drop the packet. If not, let the packet
# through.
#
# Fail2ban inserts blacklisted hosts into the fail2ban-<name> list
# and removes them from the list after some time, according to its
# own rules. The 3600 second timeout is independent and acts as a
# safeguard in case the fail2ban process dies unexpectedly. The
# shorter of the two timeouts actually matters.

# 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
#
# Another useful configuration value is <getcmd>, if you don't have wget
# installed (an example config for curl is given below)

# 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

Fail2ban normally requires root priviledges to insert iptables rules
through calls to /sbin/iptables and also to read the logfiles.
Fail2ban can run as an unpriviledged user provided that those two
capabilites are preserved. The idea is to run fail2ban as a normal
user (e.g. fail2ban) who belongs to a group which is allowed to read
logfiles. The user should also be allowed to write to
/proc/net/xt_recent/fail2ban-<name> (name is specified in the iptables
rule).
/proc/net/xt_recent/* is created by the xt_recent kernel module when
an iptables rule with '-m limit' is inserted. This file contains a
dynamic list of IP addresses which can than be used in iptables rules.
Addresses can be matched against this list, with an optional timeout.
One way to use xt_recent is to insert IPs into this list from an
iptables rule, e.g. after connecting to the SSH port three times in a
minute. This is the standard usage described in iptables(3).
Another way to use xt_recent is by inserting the rules by writing to
/proc/net/xt_recent/fail2ban-<name>. This can be performed by a fail2ban
action. Files in /proc/net/xt_recent/ are protected by normal
filesystem rules, so can be chown'ed and chmod'ed to be writable by a
certain user. After the necessary iptables rules are inserted (which
requires root priviledges), blacklisting can be perfomed by an
unpriviledged user.
Using fail2ban with xt_recent allows smarter filtering than normal
iptables rules with the xt_recent module can provide.
The disadvantage is that fail2ban cannot perform the setup by itself,
which would require the priviledge to call /sbin/iptables, and it must
be done through other means.
The primary advantage is obvious: it's generally better to run
services not as root. This setup is more robust, because xt_recent has
it's own memory management and should behave smartly in case a very
large amount of IPs is blocked. Also in case the fail2ban process dies
the rules expire automatically. In case of a large amount of blocked
IPs, traversing rules linearly for each SYN packet as fail2ban
normally inserts them will be slow, but xt_recent with the same number
of IPs would be much faster. (Didn't test this, so this is pure
handwaving, but it should really be this way ;)) From the
administrators point of view, a setup with xt_recent might also be
easier, because it's very simple to modify the permissions on
/proc/net/xt_recent/fail2ban-<name> to be readable or writable by
some user and thus allow delisting IPs by helper administrators
without the ability to mess up other iptables rules.
The xt_recent-echo jail can be used under the root user without
further configuration. To run not as root, futher setup is necessary:
- Create user:
- set FAIL2BAN_USER in /etc/default/fail2ban.
This probably should be fail2ban.
- add user fail2ban who can read /var/log/auth.log and other
necessary log files. Log files are owned by group 'adm', so
it is enough if this user belongs to this group.
The user can be created e.g. with
useradd --system --no-create-home --home-dir / --groups adm fail2ban
- Statically initialize chains firewall:
- put a rule to check the xt_recent list in the static firewall initialization
script, with names like fail2ban-ssh (action uses separate chains per each
jail, so define here the ones you need 1-per-jail)
Sample invocation might be
iptables -I INPUT -m recent --update --seconds 3600 --name fail2ban-<name> -j DROP
with <name> suitably replaced.
- suppress actionstart for iptables-xt_recent-echo action by creating an override file
iptables-xt_recent-echo.local to accompany iptables-xt_recent-echo.conf with
[Definition]
actionstart =
- Permissions:
make sure that configuration files under /etc/fail2ban are readable by
fail2ban user. Make sure that logfiles of fail2ban itself are writable
by the fail2ban user. /etc/init.d/fail2ban will change the ownership at
startup, but it is also necessary to modify /etc/logrotate.d/fail2ban.
The simplest way is to replace '# create ...' with the following
# create 640 fail2ban adm
