ver. 0.9.7 (2017/05/11) - awaiting-victory

-----------

0.9.x line is no longer heavily developed.  If you are interested in
new features (e.g. IPv6 support), please consider 0.10 branch and its
releases.

* Fixed a systemd-journal handling in fail2ban-regex (gh-1657)
* filter.d/sshd.conf
    - Fixed non-anchored part of failregex (misleading match of colon inside
      IPv6 address instead of `: ` in the reason-part by missing space, gh-1658)
      (0.10th resp. IPv6 relevant only, amend for gh-1479)
* config/pathes-freebsd.conf
    - Fixed filenames for apache and nginx log files (gh-1667)
* filter.d/exim.conf
    - optional part `(...)` after host-name before `[IP]` (gh-1751)

    - match of complex time like `D=2m42s` in regex "no MAIL in SMTP connection" (gh-1766)
* filter.d/sshd.conf
    - new aggressive rules (gh-864):
      - Connection reset by peer (multi-line rule during authorization process)
      - No supported authentication methods available
    - single line and multi-line expression optimized, added optional prefixes
      and suffix (logged from several ssh versions), according to gh-1206;
    - fixed expression received disconnect auth fail (optional space after port
      part, gh-1652)
      and suffix (logged from several ssh versions), according to gh-1206;
* filter.d/suhosin.conf
    - greedy catch-all before `<HOST>` fixed (potential vulnerability)
* filter.d/cyrus-imap.conf
    - accept entries without login-info resp. hostname before IP address (gh-1707)
* Filter tests extended with check of all config-regexp, that contains greedy catch-all
  before `<HOST>`, that is hard-anchored at end or precise sub expression after `<HOST>`

* New Actions:
    - action.d/netscaler: Block IPs on a Citrix Netscaler ADC (gh-1663)

* New Filters:
    - filter.d/domino-smtp: IBM Domino SMTP task (gh-1603)

* Introduced new log-level `MSG` (as INFO-2, equivalent to 18)

ver. 0.9.6 (2016/12/10) - stretch-is-coming

-----------

0.9.x line is no longer heavily developed.  If you are interested in
new features (e.g. IPv6 support), please consider 0.10 branch and its
releases.

* Misleading add resp. enable of (already available) jail in database, that
  induced a subsequent error: last position of log file will be never retrieved (gh-795)
* Fixed a distribution related bug within testReadStockJailConfForceEnabled
  (e.g. test-cases faults on Fedora, see gh-1353)
* Fixed pythonic filters and test scripts (running via wrong python version,
  uses "fail2ban-python" now);
* Fixed test case "testSetupInstallRoot" for not default python version (also
  using direct call, out of virtualenv);
* Fixed ambiguous wrong recognized date pattern resp. its optional parts (see gh-1512);
* FIPS compliant, use sha1 instead of md5 if it not allowed (see gh-1540)
* Monit config: scripting is not supported in path (gh-1556)
* `filter.d/apache-modsecurity.conf`
    - Fixed for newer version (one space, gh-1626), optimized: non-greedy catch-all
      replaced for safer match, unneeded catch-all anchoring removed, non-capturing
* `filter.d/asterisk.conf`
    - Fixed to match different asterisk log prefix (source file: method:)
* `filter.d/dovecot.conf`
    - Fixed failregex ignores failures through some not relevant info (gh-1623)
* `filter.d/ignorecommands/apache-fakegooglebot`
    - Fixed error within apache-fakegooglebot, that will be called
      with wrong python version (gh-1506)
* `filter.d/assp.conf`
    - Extended failregex and test cases to handle ASSP V1 and V2 (gh-1494)
* `filter.d/postfix-sasl.conf`
    - Allow for having no trailing space after 'failed:' (gh-1497)
* `filter.d/vsftpd.conf`
    - Optional reason part in message after FAIL LOGIN (gh-1543)
* `filter.d/sendmail-reject.conf`
    - removed mandatory double space (if dns-host available, gh-1579)
* filter.d/sshd.conf
    - recognized "Failed publickey for" (gh-1477);
    - optimized failregex to match all of "Failed any-method for ... from <HOST>" (gh-1479)
    - eliminated possible complex injections (on user-name resp. auth-info, see gh-1479)
    - optional port part after host (see gh-1533, gh-1581)

* New Actions:
    - `action.d/npf.conf` for NPF, the latest packet filter for NetBSD
* New Filters:
    - `filter.d/mongodb-auth.conf` for MongoDB (document-oriented NoSQL database engine)
      (gh-1586, gh-1606 and gh-1607)

* DateTemplate regexp extended with the word-end boundary, additionally to
  word-start boundary
* Introduces new command "fail2ban-python", as automatically created symlink to
  python executable, where fail2ban currently installed (resp. its modules are located):
    - allows to use the same version, fail2ban currently running, e.g. in
      external scripts just via replace python with fail2ban-python:
      ```diff
      -#!/usr/bin/env python
      +#!/usr/bin/env fail2ban-python
      ```
    - always the same pickle protocol
    - the same (and also guaranteed available) fail2ban modules
    - simplified stand-alone install, resp. stand-alone installation possibility
      via setup (like gh-1487) is getting closer
* Several test cases rewritten using new methods assertIn, assertNotIn
* New forward compatibility method assertRaisesRegexp (normally python >= 2.7).
  Methods assertIn, assertNotIn, assertRaisesRegexp, assertLogged, assertNotLogged
  are test covered now
* Jail configuration extended with new syntax to pass options to the backend (see gh-1408),
  examples:
    - `backend = systemd[journalpath=/run/log/journal/machine-1]`
    - `backend = systemd[journalfiles="/run/log/journal/machine-1/system.journal, /run/log/journal/machine-1/user.journal"]`
    - `backend = systemd[journalflags=2]`

ver. 0.9.5 (2016/07/15) - old-not-obsolete

    if used "INSERT OR REPLACE" statement
  • asyncserver (asyncore) code fixed and test cases repaired (again gh-161)
  • testSocket: sporadical bug repaired - wait for server thread starts a socket (listener)

    use 1h instead of 3600, 1d instead of 86400, etc
  • seekToTime - prevent completely read of big files first time (after start of service),
    initial seek to start time using half-interval search algorithm (see issue gh-795)

  • cache dnsToIp, ipToName to prevent long wait during retrieving of ip/name,
    especially for wrong dns or lazy dns-system
  • FailManager memory-optimization: increases performance,
    prevents memory leakage, because don't copy failures list on some operations
  • fail2ban-testcases - new options introduced:
    • -f, --fast to decrease wait intervals, avoid passive waiting, and skip
      few very slow test cases (implied memory database, see -m and no gamin tests -g)

  • roundcube-auth jail typo for logpath
  • Fix dnsToIp resolver for fqdn with large list of IPs (gh-1164)
  • filter.d/apache-badbots.conf
    • Updated useragent string regex adding escape for +

    • Updated "Access denied ..." regex for MySQL 5.6 and later (gh-1211, gh-1332)
  • filter.d/sshd.conf
    • Updated "Auth fail" regex for OpenSSH 5.9 and later

• New Features:
  • New interpolation feature for definition config readers - <known/parameter>
    (means last known init definition of filters or actions with name parameter).
    This interpolation makes possible to extend a parameters of stock filter or
    action directly in jail inside jail.local file, without creating a separately
    filter.d/*.local file.
    As extension to interpolation %(known/parameter)s, that does not works for
    filter and action init parameters
  • New actions:
    • nftables-multiport and nftables-allports - filtering using nftables
      framework. Note: it requires a pre-existing chain for the filtering rule.

    • murmur - bans TCP and UDP from the bad host on the default murmur port.
  • sshd filter got new failregex to match "maximum authentication
    attempts exceeded" (introduced in openssh 6.8)
  • Added filter for Mac OS screen sharing (VNC) daemon
• Enhancements:
  • Do not rotate empty log files

    .service file -- would reload fail2ban if those services are restarted
  • Provides new default fail2ban_version and interpolation variable
    fail2ban_agent in jail.conf

    and to support multiple instances of postfix having varying suffix (gh-1331)
    (Thanks Tom Hendrikx)
  • files/gentoo-initd to use start-stop-daemon to robustify restarting the service

ver. 0.9.3 (2015/08/01) - lets-all-stay-friends

----------

- IMPORTANT incompatible changes:
   * filter.d/roundcube-auth.conf
     - Changed logpath to 'errors' log (was 'userlogins')
   * action.d/iptables-common.conf
     - All calls to iptables command now use -w switch introduced in
       iptables 1.4.20 (some distribution could have patched their
       earlier base version as well) to provide this locking mechanism
       useful under heavy load to avoid contesting on iptables calls.
       If you need to disable, define 'action.d/iptables-common.local'
       with empty value for 'lockingopt' in `[Init]` section.
   * mail-whois-lines, sendmail-geoip-lines and sendmail-whois-lines
     actions now include by default only the first 1000 log lines in
     the emails.  Adjust <grepopts> to augment the behavior.

- Fixes:
   * reload in interactive mode appends all the jails twice (gh-825)
   * reload server/jail failed if database used (but was not changed) and
     some jail active (gh-1072)
   * filter.d/dovecot.conf - also match unknown user in passwd-file.
     Thanks Anton Shestakov
   * Fix fail2ban-regex not parsing journalmatch correctly from filter config
   * filter.d/asterisk.conf - fix security log support for Asterisk 12+
   * filter.d/roundcube-auth.conf
     - Updated regex to work with 'errors' log (1.0.5 and 1.1.1)
     - Added regex to work with 'userlogins' log
   * action.d/sendmail*.conf - use LC_ALL (superseeding LC_TIME) to override
     locale on systems with customized LC_ALL
   * performance fix: minimizes connection overhead, close socket only at
     communication end (gh-1099)
   * unbanip always deletes ip from database (independent of bantime, also if
     currently not banned or persistent)
   * guarantee order of dbfile to be before dbpurgeage (gh-1048)
   * always set 'dbfile' before other database options (gh-1050)
   * kill the entire process group of the child process upon timeout (gh-1129).
     Otherwise could lead to resource exhaustion due to hanging whois
     processes.
   * resolve /var/run/fail2ban path in setup.py to help installation
     on platforms with /var/run -> /run symlink (gh-1142)

- New Features:
   * RETURN iptables target is now a variable: <returntype>
   * New type of operation: pass2allow, use fail2ban for "knocking",
     opening a closed port by swapping blocktype and returntype
   * New filters:
     - froxlor-auth - Thanks Joern Muehlencord
     - apache-pass - filter Apache access log for successful authentication
   * New actions:
     - shorewall-ipset-proto6 - using proto feature of the Shorewall. Still requires
       manual pre-configuration of the shorewall. See the action file for detail.
   * New jails:
     - pass2allow-ftp - allows FTP traffic after successful HTTP authentication

- Enhancements:
   * action.d/cloudflare.conf - improved documentation on how to allow
     multiple CF accounts, and jail.conf got new compound action
     definition action_cf_mwl to submit cloudflare report.
   * Check access to socket for more detailed logging on error (gh-595)
   * fail2ban-testcases man page
   * filter.d/apache-badbots.conf, filter.d/nginx-botsearch.conf - add
     HEAD method verb
   * Revamp of Travis and coverage automated testing
   * Added a space between IP address and the following colon
     in notification emails for easier text selection
   * Character detection heuristics for whois output via optional setting
     in mail-whois*.conf. Thanks Thomas Mayer.
     Not enabled by default, if _whois_command is set to be
     %(_whois_convert_charset)s (e.g. in action.d/mail-whois-common.local),
     it
     - detects character set of whois output (which is undefined by
       RFC 3912) via heuristics of the file command
     - converts whois data to UTF-8 character set with iconv
     - sends the whois output in UTF-8 character set to mail program
     - avoids that heirloom mailx creates binary attachment for input with
       unknown character set

better-quick-now-than-later

Long delayed

ver. 0.9.2 (2015/04/29) - better-quick-now-than-later

   * $ typo in jail.conf. Thanks Skibbi. Debian bug #767255
   * grep'ing for IP in *mail-whois-lines.conf should now match also
     at the beginning and EOL.  Thanks Dean Lee
   * jail.conf
     - php-url-fopen: separate logpath entries by newline
   * failregex declared direct in jail was joined to single line (specifying of
     multiple expressions was not possible).
   * filters.d/exim.conf - cover different settings of exim logs
     details. Thanks bes.internal
   * filter.d/postfix-sasl.conf - failregex is now case insensitive
   * filters.d/postfix.conf - add 'Client host rejected error message' failregex
   * fail2ban/__init__.py - add strptime thread safety hack-around
   * recidive uses iptables-allports banaction by default now.
     Avoids problems with iptables versions not understanding 'all' for
     protocols and ports
   * filter.d/dovecot.conf
     - match pam_authenticate line from EL7
     - match unknown user line from EL7
   * Use use_poll=True for Python 2.7 and >=3.4 to overcome "Bad file
     descriptor" msgs issue (gh-161)
   * filter.d/postfix-sasl.conf - tweak failregex and add ignoreregex to ignore
     system authentication issues
   * fail2ban-regex reads filter file(s) completely, incl. '.local' file etc.
     (gh-954)
   * firewallcmd-* actions: split output into separate lines for grepping (gh-908)
   * Guard unicode encode/decode issues while storing records in the database.
     Fixes "binding parameter error (unsupported type)" (gh-973), thanks to kot
     for reporting
   * filter.d/sshd added regex for matching openSUSE ssh authentication failure
   * filter.d/asterisk.conf:
     - Dropped "Sending fake auth rejection" failregex since it incorrectly
       targets the asterisk server itself
     - match "hacking attempt detected" logs

- New Features:

     - postfix-rbl  Thanks Lee Clemens
     - apache-fakegooglebot.conf  Thanks Lee Clemens
     - nginx-botsearch  Thanks Frantisek Sumsal
     - drupal-auth  Thanks Lee Clemens

     - `<<PREF>HOST>` becomes `<IPV4HOST>` for PREF=`IPV4`;
     - `<<PREF>HOST>` becomes `1.2.3.4` for PREF=`IPV4` and IPV4HOST=`1.2.3.4`;
   - New interpolation feature for config readers - `%(known/parameter)s`.
     (means last known option with name `parameter`). This interpolation makes
     possible to extend a stock filter or jail regexp in .local file
     (opposite to simply set failregex/ignoreregex that overwrites it),
     see gh-867.
   - Monit config for fail2ban in files/monit/
   - New actions:
     - action.d/firewallcmd-multiport and action.d/firewallcmd-allports Thanks Donald Yandt
     - action.d/sendmail-geoip-lines.conf
     - action.d/nsupdate to update DNSBL. Thanks Andrew St. Jean
   - New status argument for fail2ban-client -- flavor:
     fail2ban-client status <jail> [flavor]
     - empty or "basic" works as-is
     - "cymru" additionally prints (ASN, Country RIR) per banned IP
       (requires dnspython or dnspython3)
   - Flush log at USR1 signal

- Enhancements:
   * Enable multiport for firewallcmd-new action.  Closes gh-834
   * files/debian-initd migrated from the debian branch and should be
     suitable for manual installations now (thanks Juan Karlo de Guzman)
   * Define empty ignoreregex in filters which didn't have it to avoid
     warnings (gh-934)
   * action.d/{sendmail-*,xarf-login-attack}.conf - report local
     timezone not UTC time/zone. Closes gh-911
   * Conditionally log Ignore IP with reason (dns, ip, command). Closes gh-916
   * Absorbed DNSUtils.cidr into addr2bin in filter.py, added unittests
   * Added syslogsocket configuration to fail2ban.conf
   * Note in the jail.conf for the recidive jail to increase dbpurgeage (gh-964)

better, faster, stronger

ver. 0.9.1 (2014/10/29) - 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
• Fixes:
  • start of file2ban aborted (on slow hosts, systemd considers the server has
    been timed out and kills him), see gh-824
  • 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
  • journalmatch for recidive incorrect PRIORITY
  • 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
  • postfix* - match with a new daemon string (postfix/submission/smtpd).
    Closes gh-804 . Thanks Paul Traina

  • fail2ban-client can fetch the running server version
  • Added Cloudflare API action
• Enhancements
  • Start performance of fail2ban-client (and tests) increased, start time
    and cpu usage rapidly reduced. Introduced a shared storage logic, to
    bypass reading lots of config files (see gh-824).
    Thanks to Joost Molenaar for good catch (reported gh-820).
  • Fail2ban-regex - add print-all-matched option. Closes gh-652
  • Suppress fail2ban-client warnings for non-critical config options
  • Match non "Bye Bye" disconnect messages for sshd locked account regex
  • courier-smtp filter:
    • match lines with user names
    • match lines containing "535 Authentication failed" attempts
