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
|
||||

||||
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
|
||||

|
||||
mod_auth_digest failures.
|
||||
* filter.d/recidive -- support f2b syslog target and anchor regex at start

|
||||
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

@ -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)
|

|
||||
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
