||||
================================================================================
|
||||
|
||||
ver. 0.9.1 (2014/xx/xx) - better, faster, stronger
|
||||
----------
|
||||
|
||||
- Refactoring (IMPORTANT -- Please review your setup and configuration):
|
||||
* iptables-common.conf replaced iptables-blocktype.conf

||||
(iptables-blocktype.local should still be read) and now also
|
||||
provides defaults for the chain, port, protocol and name tags
|
||||
ver. 0.8.14 (2014/08/19) - take-care-of-the-elderly
|
||||
-----------
|
||||
|
||||
- Fixes:
|
||||
* UTF-8 fixes in pure-ftp thanks to Johannes Weberhofer. Closes gh-806.
|
||||
* systemd backend error on bad utf-8 in python3
|
||||
* badips.py action error when logging HTTP error raised with badips request
|
||||
* fail2ban-regex failed to work in python3 due to space/tab mix
|
||||
* recidive regex samples incorrect log level
|
||||

|
||||
* loglevel couldn't be changed in fail2ban.conf
|
||||
* Handle case when no sqlite library is available for persistent database
|
||||
* Only reban once per IP from database on fail2ban restart
|
||||
* Nginx filter to support missing server_name. Closes gh-676
|
||||
* fail2ban-regex assertion error caused by miscount missed lines with
|
||||
multiline regex
|
||||
* Fix actions failing to execute for Python 3.4.0. Workaround for
|
||||
http://bugs.python.org/issue21207
|
||||
* Database now returns persistent bans on restart (bantime < 0)
|
||||
* Recursive action tags now fully processed. Fixes issue with bsd-ipfw
|
||||
action
|
||||
* Fixed TypeError with "ipfailures" and "ipjailfailures" action tags.
|
||||
Thanks Serg G. Brester
|
||||
* Correct times for non-timezone date times formats during DST
|
||||
* Pass a copy of, not original, aInfo into actions to avoid side-effects
|
||||
* Per-distribution paths to the exim's main log
|
||||
* Ignored IPs are no longer banned when being restored from persistent
|
||||
database
|
||||
* Manually unbanned IPs are now removed from persistent database, such they
|
||||
wont be banned again when Fail2Ban is restarted
|
||||
* Pass "bantime" parameter to the actions in default jail's action
|
||||
definition(s)
|
||||
* filters.d/sieve.conf - fixed typo in _daemon. Thanks Jisoo Park
|
||||
* cyrus-imap -- also catch also failed logins via secured (imaps/pop3s).
|
||||
Regression was introduced while strengthening failregex in 0.8.11 (bd175f)
|
||||
Debian bug #755173
|
||||
* postfix-sasl -- added journalmatch. Thanks Luc Maisonobe
|
||||
- minor fixes for claimed Python 2.4 and 2.5 compatibility
|
||||
- Handle case when inotify watch is auto deleted on file deletion to stop
|
||||
error messages
|
||||
- tests - fixed few "leaky" file descriptors when files were not closed while
|
||||
being removed physically
|
||||
- grep in mail*-whois-lines.conf now also matches end of line to work
|
||||
with the recidive filter
|
||||
- filters.d/sieve.conf - fixed typo in _daemon. Thanks Jisoo Park
|
||||
|

|
||||
|
||||
ver. 0.9.0 (2014/03/14) - beta
|
||||
----------
|
||||
|
||||
Carries all fixes, features and enhancements from 0.8.13 (unreleased) with
|
||||
major changes.
|
||||
|
||||
The minimum supported python version is now 2.6. If you have python-2.4 or 2.5
|
||||
you can use the 0.8.12 version of fail2ban.
|
||||
|
||||
Please take note of release notes:
|
||||
https://github.com/fail2ban/fail2ban/releases/tag/0.9.0
|
||||
|
||||
Please test your configuration before relying on it.
|
||||
|
||||
Nearly all development is thanks to Steven Hiscocks (THANKS!), merging,
|
||||
testcases and timezone support from Daniel Black, and code-review and minor
|
||||
additions from Yaroslav Halchenko.
|
||||
|
||||
- Refactoring (IMPORTANT -- Please review your setup and configuration):
|
||||
* [..bddbf1e] jail.conf was heavily refactored and now is similar
|
||||
to how it looked on Debian systems:
|
||||
- default action could be configured once for all jails
|
||||
- jails definitions only provide customizations (port, logpath)
|
||||
- no need to specify 'filter' if name matches jail name
|
||||
* [..5aef036] Core functionality moved into fail2ban/ module.
|
||||
Closes gh-26
|
||||
- tests included in module to aid testing and debugging
|
||||
* Added fail2ban persistent database
|
||||
- default location at /var/lib/fail2ban/fail2ban.sqlite3
|
||||
- allows active bans to be reinstated on restart
|
||||
- log files read from last position after restart
|
||||
* Added systemd journal backend
|
||||
- Dependency on python-systemd
|
||||
- New "journalmatch" option added to filter configs files
|
||||
- New "systemd-journal" option added to fail2ban-regex
|
||||
* Added python3 support
|
||||
* Support %z (Timezone offset) and %f (sub-seconds) support for
|
||||
datedetector. Enhanced existing date/time have been updated patterns to
|
||||
support these. ISO8601 now defaults to localtime unless specified otherwise.
|
||||
Some filters have been change as required to capture these elements in the
|
||||
right timezone correctly.
|
||||
* Log levels are now set by Syslog style strings e.g. DEBUG, ERROR.
|
||||
- Log level INFO is now more verbose
|
||||
* Optionally can read log files starting from "head" or "tail".
|
||||
- See "logpath" option in jail.conf(5) man page.
|
||||
* Can now set log encoding for files per jail.
|
||||
- Default uses systemd locale.
|
||||
|
||||
- New features:
|
||||
* [..c7ae460] Multiline failregex. Close gh-54
|
||||
* [8af32ed] Guacamole filter and support for Apache Tomcat date
|
||||
format
|
||||
* [..b6059f4] 'timeout' option for actions Close gh-60 and Debian bug

diff -rul --exclude \*.pyc . /tmp/fail2ban-0.9.0/
|
||||
|
||||
* 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
|
||||
|
||||
* To generate a list of committers use e.g.::
|
||||
|
||||
git shortlog -sn 0.8.12.. | sed -e 's,^[ 0-9\t]*,,g' | tr '\n' '\|' | sed -e 's:|:, :g'
|
||||
|
||||
* 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.

||||
(cd man ; ./generate-man )
|
||||
git commit -m 'DOC/ENH: update man pages for release' man/*
|
||||
|
||||

fail2ban (0.7.1-0.2) unstable; urgency=low
|
||||
|
||||
fail2ban 0.7 is a complete rewrite of the 0.6 version, and if you
|
||||
customized any of provided configuration or startup files
|
||||
(/etc/default/fail2ban, /etc/fail2ban.conf, /etc/init.d/fail2ban),
|
||||
please read further. The configuration scheme has changed upstream:
|
||||
0.7 ignores /etc/fail2ban.conf and instead uses a split configuration
|
||||
under /etc/fail2ban/. To retain your customizations, for example to
|
||||
monitor anything other than sshd, you will need to set them under that
|
||||
new directory; use *.local files for customizations. Please see
|
||||
/usr/share/doc/fail2ban/README.Debian.gz and
|
||||
http://fail2ban.sourceforge.net for further description of new
|
||||
configuration scheme. Detailed documentation is under development (see
|
||||
#400416). When you are satisfied with the new settings, please delete
|
||||
/etc/fail2ban.conf to avoid confusion.
|
||||
|
||||
Fail2ban 0.7 uses client/server architecture and fail2ban-client is to
|
||||
substitute fail2ban command to provide an interface between the user and
|
||||
fail2ban-server. That is why some command line parameters present in
|
||||
fail2ban 0.6 are invalid in fail2ban-client. Such change affects
|
||||
/etc/default/fail2ban; you should review that file if you customized it.
|
||||
Please enable sections as directed in README.Debian.gz mentioned above.
|
||||
You must use newly shipped init.d/fail2ban, or otherwise fail2ban will
|
||||
not start.

In this version the new section ApacheAttacks was introduced to ban IPs

which are found to run some known attack on the host. For now it captures

just awstats and mambo related attacks. To make this feature work, the bug of

wrongly specified timeregexp for Apache's access.log file was fixed.

Besides that group of log files has changed to be adm, and now they are

fail2ban (>=0.7.0) for Debian
|
||||
-----------------------------
|
||||
|
||||
This package is ~99% identical to the upstream version. Few features
|
||||
could have been added but not yet propagated into upstream version and
|
||||
some modifications might be Debian-specific. Debian specific jail.conf
|
||||
file is shipped. Original upstream file is available from
|
||||
/usr/share/doc/fail2ban/examples/jail.conf
|
||||
|
||||
Currently, the major difference with upstream: python libraries are
|
||||
placed under /usr/share/fail2ban instead of /usr/lib/fail2ban to
|
||||
comply with policy regarding architecture independent resources.
|
||||
|
||||
Upgrade from 0.6 versions:
|
||||
-------------------------
|
||||
|
||||
* New Config Files Format:
|
||||
|
||||
If you had introduced your own sections in /etc/fail2ban.conf, you
|
||||
would need manually to convert them into a new format. At minimum you
|
||||
need to create /etc/fail2ban/filter.d/NAME.local (leave .conf files
|
||||
for me and upstream please to avoid any conflicts -- introduce your
|
||||
changes in .local) with failregex in [Definition] section. And provide
|
||||
appropriate jail definition in /etc/fail2ban/jail.local
|
||||
|
||||
|
||||
* Enabled Sections:
|
||||
|
||||
Only handling of ssh files is enabled by default. If you want to use
|
||||
fail2ban with apache, please enable apache section manually in
|
||||
/etc/fail2ban/jail.local by including next lines:
|
||||
|
||||
[apache]
|
||||
enabled = true
|
||||
|
||||
NOTE: -e command line parameter is non existant in 0.7.x
|
||||
|
||||
|
||||
* Interpolations vs actions/filters parameters:
|
||||
|
||||
For details see #398739 or wait for a closure of #400416
|
||||
|
||||
Every pair of .conf and then .local (if exists) files is read
|
||||
separately from any other configuration file, so interpolations cannot
|
||||
penetrate from jail.* into actions.d/*. To overcome this, it is
|
||||
necessary to create a PARAMETER which can be substituted in actions
|
||||
[Definition] section, if it is also defined in the [Init] section of
|
||||
that file and is used in place of necessary allocation as <PARAMETER>
|
||||
tag. Parameters can be specified in the definitions within
|
||||
jail.{conf,local}. For instance, 1 lengthy example, where the same
|
||||
name "fwchain" is used both as interpolation (in jail.local) and as a
|
||||
parameter (in iptables-flex.local) (from #398739)

|
||||
|
||||
|
||||
* Multiport banning: Comment for #373592, #545971
|
||||
|
||||
iptables-multiport action is now default banaction (file jail.conf, to
|
||||
be customized within jail.local). Therefore assure that you have built
|
||||
multiport module if you use custom kernel.
|
||||
|
||||
If you would like to ban all ports for that host, just redefine
|
||||
fwban/fwunban commands to don't have --dport %(port)s statement at
|
||||
all, or use shorewall, where actionban bans whole IP.
|
||||
|
||||
* Blocking of NEW connections only
|
||||
Comment for the wishlist #350746.
|
||||
|
||||
It might be benefitial in some cases to ban only new connections. For
|
||||
that just use iptables-new action instead of default banaction
|
||||
|
||||
/etc/fail2ban/jail.local:
|
||||
|
||||
[DEFAULT]
|
||||
banaction=iptables-new
|
||||
|
||||
(you can override banaction within interesting for you section).
|
||||
Also you can redefine the whole action parameter if you like.
|
||||
|
||||
|
||||
* Interaction with ipmasq
|
||||
Comment to #461417
|
||||
|
||||
Although fail2ban should detect and recreate missing chains if the external
|
||||
command wipes out iptables, it is better to explicitly to force-reload
|
||||
fail2ban. For this reason there is examples/ipmasq-ZZZzzz|fail2ban.rul file is
|
||||
shipped along to be installed under name ZZZzzz|fail2ban.rul within
|
||||
/etc/ipmasq.
|
||||
|
||||
* Interaction with logrotate with custom logtarget
|
||||
Comment to #631917
|
||||
|
||||
if you use an alternative logtarget (e.g. SYSLOG) thus not using
|
||||
/var/log/fail2ban.log you should divert logrotate configuration into
|
||||
a disabled state, e.g.
|
||||
|
||||
sudo dpkg-divert --rename --divert \
|
||||
/etc/logrotate.d/fail2ban.disabled /etc/logrotate.d/fail2ban
|
||||
|
||||
|
||||
Troubleshooting:
|
||||
---------------
|
||||
|
||||
* Updated failregex:
|
||||
|
||||
To resolve the security bug #330827 [1] failregex expressions must
|
||||
provide a named group (?P<host>...) as a placeholder of the abuser's
|
||||
host. Alternative tag (since 0.7.5) can be "<HOST>". The naming of the
|
||||
group was introduced to capture possible future generalizations of
|
||||
failregex to provide even more information.
|
||||
|
||||
[1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=330827
|
||||
|
||||
You might benefit from using fail2ban-regex command shipped along to
|
||||
construct and debug your failregex statements.
|
||||
|
||||
* "Interpolations" in the config file:
|
||||
|
||||
Since version 0.6.0-3 to reduce duplication, thus to improve
|
||||
readability of the config file, interpolations provided by the module
|
||||
ConfigParser are used. If you had custom sections defined before, you
|
||||
might benefit from updating config file and adding appropriate
|
||||
information for the new sections.
|
||||
|
||||
N.B. If you have some nice additional sections defined, I would really
|
||||
appreciate if you share them with me or upstream author, so they could
|
||||
be eventually included in the fail2ban package for general use by the
|
||||
rest of the community.
|
||||
|
||||
|
||||
* Mailing:
|
||||
|
||||
Since actions.d/mail*.conf commands rely on presence of "mail"
|
||||
command, mailx package (or another package providing mailx
|
||||
functionality such as mailutils) is required if those actions are
|
||||
activated in jail.{conf,local}.
|
||||
|
||||
|
||||
* Dirty exit:
|
||||
|
||||
If firewall rules gets cleaned out before fail2ban exits (like was
|
||||
happening with firestarter), errors get reported during the exit of
|
||||
fail2ban, but they are "safe" and can be ignored.
|
||||
|
||||
|
||||
** SSHD Configuration Specific Problems
|
||||
|
||||
* Ban "Not allowed" attempts:
|
||||
|
||||
Make sure that you have
|
||||
ChallengeResponseAuthentication no
|
||||
PasswordAuthentication yes
|
||||
|
||||
Details from the bug report #350980 [2]
|
||||
|
||||
[2] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=350980
|
||||
|
||||
|
||||
* Not caught attempts to login as root
|
||||
|
||||
On the boxes running older versions of openssh (e.g. sarge
|
||||
distribution) in the case when PermitRootLogin is set to something
|
||||
else than "yes" and iff AllowUsers is active, failed root logins do
|
||||
not confirm to the standard logging message -- they omit the source
|
||||
IP, thus allowing attack to persist since such messages are not caught
|
||||
by fail2ban.
|
||||
|
||||
|
||||
* Bantime:
|
||||
|
||||
An IP is banned for "bantime" not since the last failed login attempt
|
||||
from the IP, but rather since the moment when failed login was
|
||||
detected by fail2ban. Thus, if fail2ban gets [re]started, any IP which
|
||||
had enough of failed logins with durations less than "findtime" between
|
||||
them prior to the [re]start moment, will be banned for
|
||||
"bantime" since [re]start moment, not since the last failed login
|
||||
time.
|
||||
|
||||
* Findtime:
|
||||
|
||||
"Findtime" option of a jail actually defines a duration to reset the
|
||||
counter of failed login attempts, if no new attempt was detected within
|
||||
that time frame (i.e. within "findtime").
|
||||
|
||||
See
|
||||
http://www.fail2ban.org/wiki/index.php/MANUAL_0_8#Jail_Options
|
||||
for more information on jail options.

|
||||
|
||||
Especially on systems wich provide ssh/CGI/PHP services to unknown
|
||||
users it is possible to block other users from ssh and probably other
|
||||
access as a unprivileged user may issue:
|
||||
|
||||
logger -p auth.warning -t 'sshd[123]' 'Illegal user user1 from 1.2.3.4'
|
||||
|
||||
N.B. chmod o-x /usr/bin/logger should provide at least obfuscation
|
||||
solution
|
||||
|
||||
Or the malicious user may write via PHP's openlog()/syslog() to syslog.
|
||||
|
||||
P.S. Anyone is welcome to recommend proper security solution to this
|
||||
issue, such as an alternative to sysklogd which allows better control
|
||||
over users logging to specific facilities (such as AUTH)
