Fail2Ban (version 0.8.7.1) 2012/07/31
Fail2Ban (version 0.8.10) 2013/06/12
================================================================================
ver. 0.8.11 (2013/XX/XXX) - loves-unittests
-----------
- Fixes:
Daniel Black & Marcel Dopita
* filter.d/apache-auth -- fixed and apache auth samples provide. closes #286
Yaroslav Halchenko
* filter.d/common.conf -- make colon after [daemon] optional. Closes gh-267
* filter.d/apache-common.conf -- support apache 2.4 more detailed error
log format. Closes gh-268
* Backends changes detection and parsing. Close gh-223 and gh-103:
- Polling backend: detect changes in the files not only based on
mtime, but also on the size and inode. It should allow for
better detection of changes and log rotations on busy servers,
older python 2.4, and file systems with precision of mtime only
up to a second (e.g. ext3).
- All backends, possible race condition: do not read from a file
initially reported empty. Originally could have lead to
accounting for detected log lines multiple times.
- Do not crash if executing a command in fail2ban-client interactive
mode has failed (e.g. due to incorrect syntax). Closes gh-353
Daniel Black & Мернов Георгий
* filter.d/dovecot.conf -- Fix when no TLS enabled - line doesn't end in ,
Daniel Black
* action.d/hostsdeny -- NOTE: new dependancy 'ed'. Switched to use 'ed' across
all platforms to ensure permissions are the same before and after a ban -
closes gh-266. hostsdeny supports daemon_list now too.
* filter.d/roundcube-auth - timezone offset can be positive or negative
* action.d/bsd-ipfw - action option unsed. Fixed to blocktype for
consistency. default to port unreach instead of deny
Rolf Fokkens
* action.d/dshield.conf and complain.conf -- reorder mailx arguments.
https://bugzilla.redhat.com/show_bug.cgi?id=998020
John Doe (ache)
* action.d/bsd-ipfw.conf - invert actionstop logic to make exist status 0.
closes gh-343.
JP Espinosa (Reviewed by O.Poplawski)
* files/redhat-initd - rewritten to use stock init.d functions thus
avoiding problems with getpid. Also $network and iptables moved
to Should- rc init fields
- New Features:
Andy Fragen and Daniel Black
* filter.d/osx-ipfw.conf - ipfw action for OSX based on random rule
numbers.
Daniel Black & ykimon
* filter.d/3proxy.conf -- filter added
Daniel Black
* filter.d/exim-spam.conf -- a splitout of exim's spam regexes
with additions for greater control over filtering spam.
* add date expression for apache-2.4 - milliseconds
Christophe Carles & Daniel Black
* filter.d/perdition.conf -- filter added
- Enhancements:
François Boulogne and Frédéric
* filter.d/lighttpd - auth regexs for lighttpd-1.4.31
Daniel Black
* filter.d/{asterisk,assp,dovecot,proftpd}.conf -- regex hardening
and extra failure examples in sample logs
* filter.d/apache-auth - added expressions for mod_authz, mod_auth and
mod_auth_digest failures.
* filter.d/recidive -- support f2b syslog target and anchor regex at start
* filter.d/pam-generic - added syslog prefix. Disabled support for
linux-pam before version 0.99.2.0 (2005)
* filter.d/gssftpd - anchored regex at start
* filter.d/mysqld-auth.conf - mysql can use syslog
Daniel Black & Georgiy Mernov & ftoppi & Мернов Георгий

sample logs
* filter.d/named-refused.conf - BIND 9.9.3 regex changes
Daniel Black & Sebastian Arcus
* filter.d/asterisk -- more regexes
Yaroslav Halchenko
* fail2ban-regex -- refactored to provide more details (missing and
ignored lines, control over logging, etc) while maintaining look&feel
* fail2ban-client -- log to standard error. Closes gh-264
* Fail to configure if not a single log file was found for an
enabled jail. Closes gh-63
* <HOST> is now enforced to end with an alphanumeric
* filter.d/roundcube-auth.conf -- anchored version
* date matching - for standard asctime formats prefer more detailed
first (thus use year if available)
Alexander Dietrich
* action.d/sendmail-common.conf -- added common sendmail settings file
and made the sender display name configurable
Steven Hiscocks
* filter.d/dovecot - Addition of session, time values and possible blank
user

@ -21,17 +21,247 @@ 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)
Testing
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 adminstrators
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.
Filters
=======
Existing tests can be run by executing `fail2ban-testcases`.
* Include sample logs with 1.2.3.4 used for IP addresses and
example.com/example.org used for DNS names
* Ensure sample log is provided in testcases/files/logs/ with same name as the
filter. Each log line should include match meta data for time & IP above
every line (see other sample log files for examples)
* Ensure regexs start with a ^ and are restrictive as possible. E.g. not .* if
\d+ is sufficient
* Use the functionality of regexs http://docs.python.org/2/library/re.html
* Take a look at the source code of the application. You may see optional or
extra log messages, or parts there of, that need to form part of your regex.
If you only have a basic knowledge of regular repressions read
http://docs.python.org/2/library/re.html first.
Filter Security
---------------
Poor filter regular expressions are suseptable to DoS attacks.
When a remote user has the ability to introduce text that will match the
filter regex, such that the inserted text matches 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 a sufficient extent that the user cannot insert the entire text.
Filters are matched against the log line with their date removed.
Ideally filter regex should anchor to the beginning and end of the log line
however as more applications log at the beginning than the end, achoring 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 regexs of the filter are sufficient to mitigate the
risk of insertion.
When creating a regex that extends back to the begining remember the date part
has been removed within fail2ban so theres no need to match that. If the format
is like '<date...> error 1.2.3.4 is evil' then you will need to match the < at
the start so here the regex would start like '^<> <HOST> is evil$'.
Some applications log spaces at the end. If you're not sure add \s*$ as the
end part of the regex.
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 diliently 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 approprate.
^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. Filter 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. Applicaiton generates two identical log messages with different meanings
If the application generates the following two messages under different
circmstances:
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.
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 codebase. 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
Documentation about creating tests (when tests are required and some guidelines
for creating good tests) will be added soon.
Coding Standards
================
Coming Soon.
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.

Fail2Ban (version 0.8.7) 2012/07/31
================================================================================
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-0.8.7.tar.bz2
> cd fail2ban-0.8.7
> 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

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 derivates. 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 et cetera 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

# This is for blocking whole hosts through blackhole routes.
#
# PRO:
# - Works on all kernel versions and as no compatibility problems (back to debian lenny and WAY further).
# - It's FAST for very large numbers of blocked ips.
# - It's FAST because it Blocks traffic before it enters common iptables chains used for filtering.
# - It's per host, ideal as action against ssh password bruteforcing to block further attack attempts.
# - No additional software required beside iproute/iproute2
#
# CON:
# - Blocking is per IP and NOT per service, but ideal as action against ssh password bruteforcing hosts
