Fail2Ban: Changelog |
|
=================== |
|
|
|
ver. 1.0.3-dev-1 (20??/??/??) - development nightly edition |
|
----------- |
|
|
|
### Fixes |
|
* circumvent SEGFAULT in a python's socket module by getaddrinfo with disabled IPv6 (gh-3438) |
|
* `action.d/cloudflare-token.conf` - fixes gh-3479, url-encode args by unban |
|
* `action.d/*ipset*`: make `maxelem` ipset option configurable through banaction arguments (gh-3564) |
|
|
|
### New Features and Enhancements |
|
* `fail2ban-regex` extended to load settings from jail (by simple name it'd prefer jail to the filter now, gh-2655); |
|
to load the settings from filter one could use: |
|
```diff |
|
- fail2ban-regex ... sshd ; # jail |
|
+ fail2ban-regex ... sshd.conf ; # filter |
|
# or: |
|
+ fail2ban-regex ... filter.d/sshd ; # filter |
|
``` |
|
* better auto-detection for IPv6 support (`allowipv6 = auto` by default), trying to check sysctl net.ipv6.conf.all.disable_ipv6 |
|
(value read from `/proc/sys/net/ipv6/conf/all/disable_ipv6`) if available, otherwise seeks over local IPv6 from network interfaces |
|
if available for platform and uses DNS to find local IPv6 as a fallback only |
|
* improve `ignoreself` by considering all local addresses from network interfaces additionally to IPs from hostnames (gh-3132) |
|
* `filter.d/exim.conf`, `filter.d/exim-spam.conf`: |
|
- messages are prefiltered by `prefregex` now |
|
- filter can bypass additional timestamp or pid that may be logged via systemd-journal or syslog-ng (gh-3060) |
|
- rewrite host line regex for all varied exim's log_selector states (gh-3263) |
|
- fixed "dropped: too many ..." regex, also matching unrecognized commands now (gh-3502) |
|
* `action.d/mikrotik.conf` - new action for mikrotik routerOS, adds and removes entries from address lists on the router (gh-2860) |
|
* `action.d/smtp.py` - added optional support for TLS connections via the `ssl` arg. |
|
* `filter.d/nginx-forbidden.conf` - new filter to ban forbidden locations, e. g. using `deny` directive (gh-2226) |
|
* `filter.d/sshd.conf`: |
|
- avoid double counting for "maximum authentication attempts exceeded" (gh-3502) |
|
- message "Disconnecting ... Too many authentication failures" is not a failure anymore |
|
- mode `ddos`/`aggressive` extended to match new messages caused by port scanner, wrong payload on ssh port (gh-3486): |
|
* message authentication code incorrect [preauth] |
|
* connection corrupted [preauth] |
|
* timeout before authentication |
|
|
|
|
|
ver. 1.0.2 (2022/11/09) - finally-war-game-test-tape-not-a-nuclear-alarm |
|
----------- |
|
|
|
### Fixes |
|
* backend `systemd`: code review and several fixes: |
|
- wait only if it is necessary, e. g. in operational mode and if no more entries retrieved (end of journal); |
|
- ensure we give enough time after possible rotation, vacuuming or adding/removing journal files, |
|
and move cursor back and forth to avoid entering dead space |
|
* `filter.d/named-refused.conf`: |
|
- support BIND named log categories, gh-3388 |
|
- allow `info:` as possible error prefix too ("query (cache) denied" may occur as info) |
|
* `filter.d/dovecot.conf`: |
|
- fixes regression introduced in gh-3210: resolve extremely long search by repeated apply of non-greedy RE-part |
|
with following branches (it may be extremely slow up to infinite search depending on message), gh-3370 |
|
- fixes regression and matches new format in aggressive mode too (amend to gh-3210) |
|
|
|
### New Features and Enhancements |
|
|
|
|
|
ver. 1.0.1 (2022/09/27) - energy-equals-mass-times-the-speed-of-light-squared |
|
----------- |
|
|
|
### Compatibility |
|
* the minimum supported python version is now 2.7, if you have previous python version |
|
you can use the 0.11 version of fail2ban or upgrade python (or even build it from source). |
|
* potential incompatibility by parsing of options of `backend`, `filter` and `action` parameters (if they |
|
are partially incorrect), because fail2ban could throw an error now (doesn't silently bypass it anymore). |
|
* due to fix for CVE-2021-32749 (GHSA-m985-3f3v-cwmm) the mailing action using mailutils may require extra configuration, |
|
if it is not compatible or doesn't support `-E 'set escape'` (e. g. with `mailcmd` parameter), see gh-3059 |
|
* automatic invocation of 2to3 is removed in setup now (gh-3098), there is also no option `--disable-2to3` anymore, |
|
`./fail2ban-2to3` should be called outside before setup |
|
* to v.0.11: |
|
- due to change of `actioncheck` behavior (gh-488), some actions can be incompatible as regards |
|
the invariant check, if `actionban` or `actionunban` would not throw an error (exit code |
|
different from 0) in case of unsane environment. |
|
- actions that have used tag `<ip>` (instead of `<fid>` or `<F-ID>`) to get failure-ID may become |
|
incompatible, if filter uses IP-related tags (like `<ADDR>` or `<HOST>`) additionally to `<F-ID>` |
|
and the values are different (gh-3217) |
|
|
|
### Fixes |
|
* theoretical RCE vulnerability in mailing action using mailutils (mail-whois), CVE-2021-32749, GHSA-m985-3f3v-cwmm |
|
* readline fixed to consider interim new-line character as part of code point in multi-byte logs |
|
(e. g. unicode encoding like utf-16be, utf-16le); |
|
* [stability] solves race condition with uncontrolled growth of failure list (jail with too many matches, |
|
that did not cause ban), behavior changed to ban ASAP, gh-2945 |
|
* fixes search for the best datepattern - e. g. if line is too short, boundaries check for previously known |
|
imprecise pattern may fail on incomplete lines (logging break-off, no flush, etc), gh-3020 |
|
* [stability, performance] backend `systemd`: |
|
- fixes error "local variable 'line' referenced before assignment", introduced in 55d7d9e2, gh-3097 |
|
- don't update database too often (every 10 ticks or ~ 10 seconds in production) |
|
- fixes wrong time point of "in operation" mode, gh-2882 |
|
- better avoidance of landing in dead space by seeks over journals (improved seek to time) |
|
- fixes missing space in message (tag `<matches>`) between timestamp and host if the message read from systemd journal, gh-3293 |
|
* [stability] backend `pyinotify`: fixes sporadic runtime error "dictionary changed size during iteration" |
|
* several backends optimizations (in file and journal filters): |
|
- don't need to wait if we still had log-entries from last iteration (which got interrupted for servicing) |
|
- rewritten update log/journal position, it is more stable and faster now (fewer DB access and surely up-to-date at end) |
|
* `paths-debian.conf`: |
|
- add debian path to roundcube error logs |
|
* `action.d/firewallcmd-*.conf` (multiport only): fixed port range selector, replacing `:` with `-`;" |
|
reverted the incompatibility gh-3047 introduced in a038fd5, gh-2821, because this depends now on firewalld backend |
|
(e. g. `-` vs. `:` related to `iptables` vs. `nftables`) |
|
* `action.d/nginx-block-map.conf`: reload nginx only if it is running (also avoid error in nginx-errorlog, gh-2949) |
|
* `action.d/ufw.conf`: |
|
- fixed handling on IPv6 (using prepend, gh-2331, gh-3018) |
|
- application names containing spaces can be used now (gh-656, gh-1532, gh-3018) |
|
* `filter.d/apache-fakegooglebot.conf`: |
|
- better, more precise regex and datepattern (closes possible weakness like gh-3013) |
|
- `filter.d/ignorecommands/apache-fakegooglebot` - added timeout parameter (default 55 seconds), avoid fail with timeout |
|
(default 1 minute) by reverse lookup on some slow DNS services (googlebots must be resolved fast), gh-2951 |
|
* `filter.d/apache-overflows.conf` - extended to match AH00126 error (Invalid URI ...), gh-2908 |
|
* `filter.d/asterisk.conf` - add transport to asterisk RE: call rejection messages can have the transport prefixed to the IP address, gh-2913 |
|
* `filter.d/courier-auth.conf`: |
|
- consider optional port after IP, gh-3211 |
|
- regex is rewritten without catch-all's and right anchor, so it is more stable against further modifications now |
|
* `filter.d/dovecot.conf`: |
|
- adjusted for updated dovecot log format with `read(size=...)` in message (gh-3210) |
|
- parse everything in parenthesis by auth-worker info, e. g. can match (pid=...,uid=...) too (amend to gh-2553) |
|
- extended to match prefix like `conn unix:auth-worker (uid=143): auth-worker<13247>:` |
|
(authenticate from external service like exim), gh-2553 |
|
- fixed "Authentication failure" regex, matches "Password mismatch" in title case (gh-2880) |
|
* `filter.d/drupal-auth.conf` - more strict regex, extended to match "Login attempt failed from" (gh-2742) |
|
* `filter.d/exim-common.conf` - pid-prefix extended to match `mx1 exim[...]:` (gh-2553) |
|
* `filter.d/lighttpd-auth.conf` - adjusted to the current source code + avoiding catch-all's, etc (gh-3116) |
|
* `filter.d/named-refused.conf`: |
|
- added support for alternate names (suffix), FreeIPA renames the BIND9 named daemon to named-pkcs11, gh-2636 |
|
- fixes prefix for messages from systemd journal (no mandatory space ahead, because don't have timestamp), gh-2899 |
|
* `filter.d/nginx-*.conf` - added journalmatch to nginx filters, gh-2935 |
|
* `filter.d/nsd.conf` - support for current log format, gh-2965 |
|
* `filter.d/postfix.conf`: fixes and new vectors, review and combining several regex to single RE: |
|
- mode `ddos` (and `aggressive`) extended: |
|
* to consider abusive handling of clients hitting command limit, gh-3040 |
|
* to handle postscreen's PREGREET and HANGUP messages, gh-2898 |
|
- matches rejects with "undeliverable address" (sender/recipient verification) additionally to "Unknown user", gh-3039 |
|
both are configurable now via extended parameter and can be disabled using `exre-user=` supplied in filter parameters |
|
- reject: BDAT/DATA from, gh-2927 |
|
- (since regex is more precise now) token selector changed to `[A-Z]{4}`, e. g. no matter what a command is supplied now |
|
(RCPT, EHLO, VRFY, DATA, BDAT or something else) |
|
- matches "Command rejected" and "Data command rejected" now |
|
- matches RCPT from unknown, 504 5.5.2, need fully-qualified hostname, gh-2995 |
|
- matches 550 5.7.25 Client host rejected, gh-2996 |
|
* `filter.d/sendmail-auth.conf`: |
|
- detect several "authentication failure" messages, sendmail 8.16.1, gh-2757 |
|
- detect user not found, gh-3030 |
|
- detect failures without user part, gh-3324 |
|
* `filter.d/sendmail-reject.conf`: |
|
- fix reverse DNS for ... (gh-3012) |
|
- fixed regex to consider "Connection rate limit exceeded" with different combination of arguments |
|
* `filter.d/sshd.conf`: |
|
- mode `ddos` extended - recognizes messages "kex_exchange_identification: Connection closed / reset by pear", gh-3086 |
|
(fixed possible regression of f77398c) |
|
- mode `ddos` extended - recognizes new message "banner exchange: invalid format" generated by port scanner |
|
(https payload on ssh port), gh-3169 |
|
* `filter.d/zoneminder.conf` - support new log format (ERR instead of WAR), add detection of non-existent user login attempts, gh-2984 |
|
* amend to gh-980 fixing several actions (correctly supporting new enhancements now) |
|
* fixed typo by `--dump-pretty` option which did never work (only `--dp` was working) |
|
* fixes start of fail2ban-client in docker: speedup daemonization process by huge open files limit, gh-3334 |
|
* provides details of failed regex compilation in the error message we throw in Regex-constructor |
|
(it's good to know what exactly is wrong) |
|
* fixed failed update of database didn't signal with an error, gh-3352: |
|
- client and server exit with error code by failure during start process (in foreground mode) |
|
- added fallback to repair if database cannot be upgraded |
|
|
|
### New Features and Enhancements |
|
* python 3.10 and 3.11 compatibility (and GHA-CI support) |
|
* `actioncheck` behavior is changed now (gh-488), so invariant check as well as restore or repair |
|
of sane environment (in case of recognized unsane state) would only occur on action errors (e. g. |
|
if ban or unban operations are exiting with other code as 0) |
|
* better recognition of log rotation, better performance by reopen: avoid unnecessary seek to begin of file |
|
(and hash calculation) |
|
* file filter reads only complete lines (ended with new-line) now, so waits for end of line (for its completion) |
|
* datedetector: |
|
- token `%Z` must recognize zone abbreviation `Z` (GMT/UTC) also (similar to `%z`) |
|
- token `%Z` recognizes all known zone abbreviation besides Z, GMT, UTC correctly, if it is matching |
|
(`%z` remains unchanged for backwards-compatibility, see comment in code) |
|
- date patterns `%ExY` and `%Exy` accept every year from 19xx up to current century (+3 years) in `fail2ban-regex` |
|
- better grouping algorithm for resulting century RE for `%ExY` and `%Exy` |
|
* actions differentiate tags `<ip>` and `<fid>` (`<F-ID>`), if IP-address deviates from ID then the value |
|
of `<ip>` is not equal `<fid>` anymore (gh-3217) |
|
* action info extended with new members for jail info (usable as tags in command actions), gh-10: |
|
- `<jail.found>`, `<jail.found_total>` - current and total found failures |
|
- `<jail.banned>`, `<jail.banned_total>` - current and total bans |
|
* `filter.d/monitorix.conf` - added new filter and jail for Monitorix, gh-2679 |
|
* `filter.d/mssql-auth.conf` - new filter and jail for Microsoft SQL Server, gh-2642 |
|
* `filter.d/nginx-bad-request.conf` - added filter to find bad requests (400), gh-2750 |
|
* `filter.d/nginx-http-auth.conf` - extended with parameter mode, so additionally to `auth` (or `normal`) |
|
mode `fallback` (or combined as `aggressive`) can find SSL errors while SSL handshaking, gh-2881 |
|
* `filter.d/scanlogd.conf` - new filter and jail, add support for filtering out detected port scans via scanlogd, gh-2950 |
|
* `action.d/apprise.conf` - added Apprise support (50+ Notifications), gh-2565 |
|
* `action.d/badips.*` - removed actions, badips.com is no longer active, gh-2889 |
|
* `action.d/cloudflare.conf` - better IPv6 capability, gh-2891 |
|
* `action.d/cloudflare-token.conf` - added support for Cloudflare Token APIs. This method is more restrictive and therefore safter than using API Keys. |
|
* `action.d/ipthreat.conf` - new action for IPThreat integration, gh-3349 |
|
* `action.d/ufw.conf` (gh-3018): |
|
- new option `add` (default `prepend`), can be supplied as `insert 1` for ufw versions before v.0.36 (gh-2331, gh-3018) |
|
- new options `kill-mode` and `kill` to drop established connections of intruder (see action for details, gh-3018) |
|
* `iptables` and `iptables-ipset` actions extended to support multiple protocols with single action |
|
for multiport or oneport type (back-ported from nftables action); |
|
* `iptables` actions are more breakdown-safe: start wouldn't fail if chain or rule already exists |
|
(e. g. created by previous instance and doesn't get purged properly); ultimately closes gh-980 |
|
* `ipset` actions are more breakdown-safe: start wouldn't fail if set with this name already exists |
|
(e. g. created by previous instance and don't deleted properly) |
|
* replace internals of several `iptables` and `iptables-ipset` actions using internals of iptables include: |
|
- better check mechanism (using `-C`, option `--check` is available long time); |
|
- additionally iptables-ipset is a common action for `iptables-ipset-proto6-*` now (which become obsolete now); |
|
- many features of different iptables actions are combinable as single chain/rule (can be supplied to action as parameters); |
|
- iptables is a replacement for iptables-common now, several actions using this as include now become obsolete; |
|
* new logtarget SYSTEMD-JOURNAL, gh-1403 |
|
* fail2ban.conf: new fail2ban configuration option `allowipv6` (default `auto`), can be used to allow or disallow IPv6 |
|
interface in fail2ban immediately by start (e. g. if fail2ban starts before network interfaces), gh-2804 |
|
* invalidate IP/DNS caches by reload, so inter alia would allow to recognize IPv6IsAllowed immediately, previously |
|
retarded up to cache max-time (5m), gh-2804 |
|
* OpenRC (Gentoo, mainly) service script improvements, gh-2182 |
|
* suppress unneeded info "Jail is not a JournalFilter instance" (moved to debug level), gh-3186 |
|
* implements new interpolation variable `%(fail2ban_confpath)s` (automatically substituted from config-reader path, |
|
default `/etc/fail2ban` or `/usr/local/etc/fail2ban` depending on distribution); `ignorecommands_dir` is unneeded anymore, |
|
thus removed from `paths-common.conf`, fixes gh-3005 |
|
* `fail2ban-regex`: accepts filter parameters containing new-line |
|
|
|
|
|
ver. 0.11.2 (2020/11/23) - heal-the-world-with-security-tools |
|
----------- |
|
|
|
### Compatibility |
|
* to v.0.10: |
|
- 0.11 is totally compatible to 0.10 (configuration- and API-related stuff), but the database |
|
got some new tables and fields (auto-converted during the first start), so once updated to 0.11, you |
|
have to remove the database /var/lib/fail2ban/fail2ban.sqlite3 (or its different to 0.10 schema) |
|
if you would need to downgrade to 0.10 for some reason. |
|
* to v.0.9: |
|
- Filter (or `failregex`) internal capture-groups: |
|
|
|
* If you've your own `failregex` or custom filters using conditional match `(?P=host)`, you should |
|
rewrite the regex like in example below resp. using `(?:(?P=ip4)|(?P=ip6)` instead of `(?P=host)` |
|
(or `(?:(?P=ip4)|(?P=ip6)|(?P=dns))` corresponding your `usedns` and `raw` settings). |
|
|
|
Of course you can always define your own capture-group (like below `_cond_ip_`) to do this. |
|
``` |
|
testln="1500000000 failure from 192.0.2.1: bad host 192.0.2.1" |
|
fail2ban-regex "$testln" "^\s*failure from (?P<_cond_ip_><HOST>): bad host (?P=_cond_ip_)$" |
|
``` |
|
* New internal groups (currently reserved for internal usage): |
|
`ip4`, `ip6`, `dns`, `fid`, `fport`, additionally `user` and another captures in lower case if |
|
mapping from tag `<F-*>` used in failregex (e. g. `user` by `<F-USER>`). |
|
|
|
- v.0.10 and 0.11 use more precise date template handling, that can be theoretically incompatible to some |
|
user configurations resp. `datepattern`. |
|
|
|
- Since v0.10 fail2ban supports the matching of IPv6 addresses, but not all ban actions are |
|
IPv6-capable now. |
|
|
|
### Fixes |
|
* [stability] prevent race condition - no ban if filter (backend) is continuously busy if |
|
too many messages will be found in log, e. g. initial scan of large log-file or journal (gh-2660) |
|
* pyinotify-backend sporadically avoided initial scanning of log-file by start |
|
* python 3.9 compatibility (and Travis CI support) |
|
* restoring a large number (500+ depending on files ulimit) of current bans when using PyPy fixed |
|
* manual ban is written to database, so can be restored by restart (gh-2647) |
|
* `jail.conf`: don't specify `action` directly in jails (use `action_` or `banaction` instead) |
|
* no mails-action added per default anymore (e. g. to allow that `action = %(action_mw)s` should be specified |
|
per jail or in default section in jail.local), closes gh-2357 |
|
* ensure we've unique action name per jail (also if parameter `actname` is not set but name deviates from standard name, gh-2686) |
|
* don't use `%(banaction)s` interpolation because it can be complex value (containing `[...]` and/or quotes), |
|
so would bother the action interpolation |
|
* fixed type conversion in config readers (take place after all interpolations get ready), that allows to |
|
specify typed parameters variable (as substitutions) as well as to supply it in other sections or as init parameters. |
|
* `action.d/*-ipset*.conf`: several ipset actions fixed (no timeout per default anymore), so no discrepancy |
|
between ipset and fail2ban (removal from ipset will be managed by fail2ban only, gh-2703) |
|
* `action.d/cloudflare.conf`: fixed `actionunban` (considering new-line chars and optionally real json-parsing |
|
with `jq`, gh-2140, gh-2656) |
|
* `action.d/nftables.conf` (type=multiport only): fixed port range selector, replacing `:` with `-` (gh-2763) |
|
* `action.d/firewallcmd-*.conf` (multiport only): fixed port range selector, replacing `:` with `-` (gh-2821) |
|
* `action.d/bsd-ipfw.conf`: fixed selection of rule-no by large list or initial `lowest_rule_num` (gh-2836) |
|
* `filter.d/common.conf`: avoid substitute of default values in related `lt_*` section, `__prefix_line` |
|
should be interpolated in definition section (inside the filter-config, gh-2650) |
|
* `filter.d/dovecot.conf`: |
|
- add managesieve and submission support (gh-2795); |
|
- accept messages with more verbose logging (gh-2573); |
|
* `filter.d/courier-smtp.conf`: prefregex extended to consider port in log-message (gh-2697) |
|
* `filter.d/traefik-auth.conf`: filter extended with parameter mode (`normal`, `ddos`, `aggressive`) to handle |
|
the match of username differently (gh-2693): |
|
- `normal`: matches 401 with supplied username only |
|
- `ddos`: matches 401 without supplied username only |
|
- `aggressive`: matches 401 and any variant (with and without username) |
|
* `filter.d/sshd.conf`: normalizing of user pattern in all RE's, allowing empty user (gh-2749) |
|
|
|
### New Features and Enhancements |
|
* fail2ban-regex: |
|
- speedup formatted output (bypass unneeded stats creation) |
|
- extended with prefregex statistic |
|
- more informative output for `datepattern` (e. g. set from filter) - pattern : description |
|
* parsing of action in jail-configs considers space between action-names as separator also |
|
(previously only new-line was allowed), for example `action = a b` would specify 2 actions `a` and `b` |
|
* new filter and jail for GitLab recognizing failed application logins (gh-2689) |
|
* new filter and jail for Grafana recognizing failed application logins (gh-2855) |
|
* new filter and jail for SoftEtherVPN recognizing failed application logins (gh-2723) |
|
* `filter.d/guacamole.conf` extended with `logging` parameter to follow webapp-logging if it's configured (gh-2631) |
|
* `filter.d/bitwarden.conf` enhanced to support syslog (gh-2778) |
|
* introduced new prefix `{UNB}` for `datepattern` to disable word boundaries in regex; |
|
* datetemplate: improved anchor detection for capturing groups `(^...)`; |
|
* datepattern: improved handling with wrong recognized timestamps (timezones, no datepattern, etc) |
|
as well as some warnings signaling user about invalid pattern or zone (gh-2814): |
|
- filter gets mode in-operation, which gets activated if filter starts processing of new messages; |
|
in this mode a timestamp read from log-line that appeared recently (not an old line), deviating too much |
|
from now (up too 24h), will be considered as now (assuming a timezone issue), so could avoid unexpected |
|
bypass of failure (previously exceeding `findtime`); |
|
- better interaction with non-matching optional datepattern or invalid timestamps; |
|
- implements special datepattern `{NONE}` - allow to find failures totally without date-time in log messages, |
|
whereas filter will use now as timestamp (gh-2802) |
|
* performance optimization of `datepattern` (better search algorithm in datedetector, especially for single template); |
|
* fail2ban-client: extended to unban IP range(s) by subnet (CIDR/mask) or hostname (DNS), gh-2791; |
|
* extended capturing of alternate tags in filter, allowing combine of multiple groups to single tuple token with new tag |
|
prefix `<F-TUPLE_`, that would combine value of `<F-V>` with all value of `<F-TUPLE_V?_n?>` tags (gh-2755) |
|
|
|
|
|
ver. 0.11.1 (2020/01/11) - this-is-the-way |
|
----------- |
|
|
|
### Fixes |
|
* purge database will be executed now (within observer). |
|
* restoring currently banned ip after service restart fixed |
|
(now < timeofban + bantime), ignore old log failures (already banned) |
|
* upgrade database: update new created table `bips` with entries from table `bans` (allows restore |
|
current bans after upgrade from version <= 0.10) |
|
|
|
### New Features |
|
* Increment ban time (+ observer) functionality introduced. |
|
* Database functionality extended with bad ips. |
|
* New tags (usable in actions): |
|
- `<bancount>` - ban count of this offender if known as bad (started by 1 for unknown) |
|
- `<bantime>` - current ban-time of the ticket (prolongation can be retarded up to 10 sec.) |
|
* Introduced new action command `actionprolong` to prolong ban-time (e. g. set new timeout if expected); |
|
Several actions (like ipset, etc.) rewritten using net logic with `actionprolong`. |
|
Note: because ban-time is dynamic, it was removed from jail.conf as timeout argument (check jail.local). |
|
|
|
### Enhancements |
|
* algorithm of restore current bans after restart changed: update the restored ban-time (and therefore |
|
end of ban) of the ticket with ban-time of jail (as maximum), for all tickets with ban-time greater |
|
(or persistent); not affected if ban-time of the jail is unchanged between stop/start. |
|
* added new setup-option `--without-tests` to skip building and installing of tests files (gh-2287). |
|
* added new command `fail2ban-client get <JAIL> banip ?sep-char|--with-time?` to get the banned ip addresses (gh-1916). |

ver. 0.10.5 (2020/01/10) - deserve-more-respect-a-jedis-weapon-must |
|
----------- |
|
|
|
Yes, Hrrrm... |
|
|
|
### Fixes |
|
* [compatibility] systemd backend: default flags changed to SYSTEM_ONLY(4), fixed in gh-2444 in order to ignore |
|
user session files per default, so could prevent "Too many open files" errors on a lot of user sessions (see gh-2392) |
|
* [grave] fixed parsing of multi-line filters (`maxlines` > 1) together with systemd backend, |
|
now systemd-filter replaces newlines in message from systemd journal with `\n` (otherwise |
|
multi-line parsing may be broken, because removal of matched string from multi-line buffer window |
|
is confused by such extra new-lines, so they are retained and got matched on every followed |
|
message, see gh-2431) |
|
* [stability] prevent race condition - no unban if the bans occur continuously (gh-2410); |
|
now an unban-check will happen not later than 10 tickets get banned regardless there are |
|
still active bans available (precedence of ban over unban-check is 10 now) |
|
* fixed read of included config-files (`.local` overwrites options of `.conf` for config-files |
|
included with before/after) |
|
* `action.d/abuseipdb.conf`: switched to use AbuseIPDB API v2 (gh-2302) |
|
* `action.d/badips.py`: fixed start of banaction on demand (which may be IP-family related), gh-2390 |
|
* `action.d/helpers-common.conf`: rewritten grep arguments, now options `-wF` used to match only |
|
whole words and fixed string (not as pattern), gh-2298 |
|
* `filter.d/apache-auth.conf`: |
|
- ignore errors from mod_evasive in `normal` mode (mode-controlled now) (gh-2548); |
|
- extended with option `mode` - `normal` (default) and `aggressive` |
|
* `filter.d/sshd.conf`: |
|
- matches `Bad protocol version identification` in `ddos` and `aggressive` modes (gh-2404). |
|
- captures `Disconnecting ...: Change of username or service not allowed` (gh-2239, gh-2279) |
|
- captures `Disconnected from ... [preauth]`, preauth phase only, different handling by `extra` |
|
(with supplied user only) and `ddos`/`aggressive` mode (gh-2115, gh-2239, gh-2279) |
|
* `filter.d/mysqld-auth.conf`: |
|
- MYSQL 8.0.13 compatibility (log-error-verbosity = 3), log-format contains few additional words |
|
enclosed in brackets after "[Note]" (gh-2314) |
|
* `filter.d/sendmail-reject.conf`: |
|
- `mode=extra` now captures port IDs of `TLSMTA` and `MSA` (defaults for ports 465 and 587 on some distros) |
|
* `files/fail2ban.service.in`: fixed systemd-unit template - missing nftables dependency (gh-2313) |
|
* several `action.d/mail*`: fixed usage with multiple log files (ultimate fix for gh-976, gh-2341) |
|
* `filter.d/sendmail-reject.conf`: fixed journal usage for some systems (e. g. CentOS): if only identifier |
|
set to `sm-mta` (no unit `sendmail`) for some messages (gh-2385) |
|
* `filter.d/asterisk.conf`: asterisk can log additional timestamp if logs into systemd-journal |
|
(regex extended with optional part matching this, gh-2383) |
|
* `filter.d/postfix.conf`: |
|
- regexp's accept variable suffix code in status of postfix for precise messages (gh-2442) |
|
- extended with new postfix filter mode `errors` to match "too many errors" (gh-2439), |
|
also included within modes `normal`, `more` (`extra` and `aggressive`), since postfix |
|
parameter `smtpd_hard_error_limit` is default 20 (additionally consider `maxretry`) |
|
* `filter.d/named-refused.conf`: |
|
- support BIND 9.11.0 log format (includes an additional field @0xXXX..., gh-2406); |
|
- `prefregex` extended, more selective now (denied/NOTAUTH suffix moved from failregex, so no catch-all there anymore) |
|
* `filter.d/sendmail-auth.conf`, `filter.d/sendmail-reject.conf` : |
|
- ID in prefix can be longer as 14 characters (gh-2563); |
|
* all filters would accept square brackets around IPv4 addresses also (e. g. monit-filter, gh-2494) |
|
* avoids unhandled exception during flush (gh-2588) |
|
* fixes pass2allow-ftp jail - due to inverted handling, action should prohibit access per default for any IP, |
|
therefore reset start on demand parameter for this action (it will be started immediately by repair); |
|
* auto-detection of IPv6 subsystem availability (important for not on-demand actions or jails, like pass2allow); |
|
|
|
### New Features |
|
* new replacement tags for failregex to match subnets in form of IP-addresses with CIDR mask (gh-2559): |
|
- `<CIDR>` - helper regex to match CIDR (simple integer form of net-mask); |
|
- `<SUBNET>` - regex to match sub-net addresses (in form of IP/CIDR, also single IP is matched, so part /CIDR is optional); |
|
* grouped tags (`<ADDR>`, `<HOST>`, `<SUBNET>`) recognize IP addresses enclosed in square brackets |
|
* new failregex-flag tag `<F-MLFGAINED>` for failregex, signaled that the access to service was gained |
|
(ATM used similar to tag `<F-NOFAIL>`, but it does not add the log-line to matches, gh-2279) |
|
* filters: introduced new configuration parameter `logtype` (default `file` for file-backends, and |
|
`journal` for journal-backends, gh-2387); can be also set to `rfc5424` to force filters (which include common.conf) |
|
to use RFC 5424 conform prefix-line per default (gh-2467); |
|
* for better performance and safety the option `logtype` can be also used to |
|
select short prefix-line for file-backends too for all filters using `__prefix_line` (`common.conf`), |
|
if message logged only with `hostname svc[nnnn]` prefix (often the case on several systems): |
|
```ini |
|
[jail] |
|
backend = auto |
|
filter = flt[logtype=short] |
|
``` |
|
* `filter.d/common.conf`: differentiate `__prefix_line` for file/journal logtype's (speedup and fix parsing |
|
of systemd-journal); |
|
* `filter.d/traefik-auth.conf`: used to ban hosts, that were failed through traefik |
|
* `filter.d/znc-adminlog.conf`: new filter for ZNC (IRC bouncer); requires the adminlog module to be loaded |
|
|
|
### Enhancements |
|
* introduced new options: `dbmaxmatches` (fail2ban.conf) and `maxmatches` (jail.conf) to control |
|
how many matches per ticket fail2ban can hold in memory and store in database (gh-2402, gh-2118); |
|
* fail2ban.conf: introduced new section `[Thread]` and option `stacksize` to configure default size |
|
of the stack for threads running in fail2ban (gh-2356), it could be set in `fail2ban.local` to |
|
avoid runtime error "can't start new thread" (see gh-969); |
|
* jail-reader extended (amend to gh-1622): actions support multi-line options now (interpolations |
|
containing new-line); |
|
* fail2ban-client: extended to ban/unban multiple tickets (see gh-2351, gh-2349); |
|
Syntax: |
|
- `fail2ban-client set <jain> banip <ip1> ... <ipN>` |
|
- `fail2ban-client set <jain> unbanip [--report-absent] <ip1> ... <ipN>` |
|
* fail2ban-client: extended with new feature which allows to inform fail2ban about single or multiple |
|
attempts (failure) for IP (resp. failure-ID), see gh-2351; |
|
Syntax: |
|
- `fail2ban-client set <jail> attempt <ip> [<failure-message1> ... <failure-messageN>]` |
|
* `action.d/nftables.conf`: |
|
- isolate fail2ban rules into a dedicated table and chain (gh-2254) |
|
- `nftables-allports` supports multiple protocols in single rule now |
|
- combined nftables actions to single action `nftables`: |
|
* `nftables-common` is removed (replaced with single action `nftables` now) |
|
* `nftables-allports` is obsolete, superseded by `nftables[type=allports]` |
|
* `nftables-multiport` is obsolete, superseded by `nftables[type=multiport]` |
|
- allowed multiple protocols in `nftables[type=multiport]` action (single set with multiple rules |
|
in chain), following configuration in jail would replace 3 separate actions, see |
|
https://github.com/fail2ban/fail2ban/pull/2254#issuecomment-534684675 |
|
* `action.d/badips.py`: option `loglevel` extended with level of summary message, |
|
following example configuration logging summary with NOTICE and rest with DEBUG log-levels: |
|
`action = badips.py[loglevel="debug, notice"]` |
|
* samplestestcase.py (testSampleRegexsFactory) extended: |
|
- allow coverage of journal logtype; |
|
- new option `fileOptions` to set common filter/test options for whole test-file; |
|
* large enhancement: auto-reban, improved invariant check and conditional operations (gh-2588): |
|
- improves invariant check and repair (avoid unhandled exception, consider family on conditional operations, etc), |
|
prepared for bulk re-ban in repair case (if bulk-ban becomes implemented); |
|
- automatic reban (repeat banning action) after repair/restore sane environment, if already logged ticket causes |
|
new failures (via new action operation `actionreban` or `actionban` if still not defined in action); |
|
* introduces banning epoch for actions and tickets (to distinguish or recognize removed set of the tickets); |
|
* invariant check avoids repair by unban/stop (unless parameter `actionrepair_on_unban` set to `true`); |
|
* better handling for all conditional operations (distinguish families for certain operations like |
|
repair/flush/stop, prepared for other families, e. g. if different handling for subnets expected, etc); |
|
* partially implements gh-980 (more breakdown safe handling); |
|
* closes gh-1680 (better as large-scale banning implementation with on-demand reban by failure, |
|
at least unless a bulk-ban gets implemented); |
|
* fail2ban-regex - several enhancements and fixes: |
|
- improved usage output (don't put a long help if an error occurs); |
|
- new option `--no-check-all` to avoid check of all regex's (first matched only); |
|
- new option `-o`, `--out` to set token only provided in output (disables check-all and outputs only expected data). |
|

ver. 0.10.4 (2018/10/04) - ten-four-on-due-date-ten-four |
|
----------- |
|
|
|
### Fixes |
|
* `filter.d/dovecot.conf`: |
|
- failregex enhancement to catch sql password mismatch errors (gh-2153); |
|
- disconnected with "proxy dest auth failed" (gh-2184); |
|
* `filter.d/freeswitch.conf`: |
|
- provide compatibility for log-format from gh-2193: |
|
* extended with new default date-pattern `^(?:%%Y-)?%%m-%%d[ T]%%H:%%M:%%S(?:\.%%f)?` to cover |
|
`YYYY-mm-dd HH:MM::SS.ms` as well as `mm-dd HH:MM::SS.ms` (so year is optional); |
|
* more optional arguments in log-line (so accept [WARN] as well as [WARNING] and optional [SOFIA] hereafter); |
|
- extended with mode parameter, allows to avoid matching of messages like `auth challenge (REGISTER)` |
|
(see gh-2163) (currently `extra` as default to be backwards-compatible), see comments in filter |
|
how to set it to mode `normal`. |
|
* `filter.d/domino-smtp.conf`: |
|
- recognizes failures logged using another format (something like session-id, IP enclosed in square brackets); |
|
- failregex extended to catch connections rejected for policy reasons (gh-2228); |
|
* `action.d/hostsdeny.conf`: fix parameter in config (dynamic parameters stating with '_' are protected |
|
and don't allowed in command-actions), see gh-2114; |
|
* decoding stability fix by wrong encoded characters like utf-8 surrogate pairs, etc (gh-2171): |
|
- fail2ban running in the preferred encoding now (as default encoding also within python 2.x), mostly |
|
`UTF-8` in opposite to `ascii` previously, so minimizes influence of implicit conversions errors; |
|
- actions: avoid possible conversion errors on wrong-chars by replace tags; |
|
- database: improve adapter/converter handlers working on invalid characters in sense of json and/or sqlite-database; |
|
additionally both are exception-safe now, so avoid possible locking of database (closes gh-2137); |
|
- logging in fail2ban is process-wide exception-safe now. |
|
* repaired start-time of initial seek to time (as well as other log-parsing related data), |
|
if parameter `logpath` specified before `findtime`, `backend`, `datepattern`, etc (gh-2173) |
|
* systemd: fixed type error on option `journalflags`: an integer is required (gh-2125); |
|
|
|
### New Features |
|
* new option `ignorecache` to improve performance of ignore failure check (using caching of `ignoreip`, |
|
`ignoreself` and `ignorecommand`), see `man jail.conf` for syntax-example; |
|
* `ignorecommand` extended to use actions-similar replacement (capable to interpolate |
|
all possible tags like `<ip-host>`, `<family>`, `<fid>`, `F-USER` etc.) |
|
|
|
### Enhancements |
|
* `filter.d/dovecot.conf`: extended with tags F-USER (and alternatives) to collect user-logins (gh-2168) |
|
* since v.0.10.4, fail2ban-client, fail2ban-server and fail2ban-regex will return version without logo info, |
|
additionally option `-V` can be used to get version in normalized machine-readable short format. |
|
|
|
|
|
ver. 0.10.3 (2018/04/04) - the-time-is-always-right-to-do-what-is-right |
|
----------- |
|
|
|
### ver. 0.10.3.1: |
|
* fixed JSON serialization for the set-object within dump into database (gh-2103). |
|
|
|
### Fixes |
|
* `filter.d/asterisk.conf`: fixed failregex prefix by log over remote syslog server (gh-2060); |
|
* `filter.d/exim.conf`: failregex extended - SMTP call dropped: too many syntax or protocol errors (gh-2048); |
|
* `filter.d/recidive.conf`: fixed if logging into systemd-journal (SYSLOG) with daemon name in prefix, gh-2069; |
|
* `filter.d/sendmail-auth.conf`, `filter.d/sendmail-reject.conf` : |
|
- fixed failregex, sendmail uses prefix 'IPv6:' logging of IPv6 addresses (gh-2064); |
|
* `filter.d/sshd.conf`: |
|
- failregex got an optional space in order to match new log-format (see gh-2061); |
|
- fixed ddos-mode regex to match refactored message (some versions can contain port now, see gh-2062); |
|
- fixed root login refused regex (optional port before preauth, gh-2080); |
|
- avoid banning of legitimate users when pam_unix used in combination with other password method, so |
|
bypass pam_unix failures if accepted available for this user gh-2070; |
|
- amend to gh-1263 with better handling of multiple attempts (failures for different user-names recognized immediately); |
|
- mode `ddos` (and `aggressive`) extended to catch `Connection closed by ... [preauth]`, so in DDOS mode |
|
it counts failure on closing connection within preauth-stage (gh-2085); |
|
* `action.d/abuseipdb.conf`: fixed curl cypher errors and comment quote-issue (gh-2044, gh-2101); |
|
* `action.d/badips.py`: implicit convert IPAddr to str, solves an issue "expected string, IPAddr found" (gh-2059); |
|
* `action.d/hostsdeny.conf`: fixed IPv6 syntax (enclosed in square brackets, gh-2066); |
|
* (Free)BSD ipfw actionban fixed to allow same rule added several times (gh-2054); |
|
|
|
### New Features |
|
* several stability and performance optimizations, more effective filter parsing, etc; |
|
* stable runnable within python versions 3.6 (as well as within 3.7-dev); |
|
|
|
### Enhancements |
|
* `filter.d/apache-auth.conf`: detection of Apache SNI errors resp. misredirect attempts (gh-2017, gh-2097); |
|
* `filter.d/apache-noscript.conf`: extend failregex to match "Primary script unknown", e. g. from php-fpm (gh-2073); |
|
* date-detector extended with long epoch (`LEPOCH`) to parse milliseconds/microseconds posix-dates (gh-2029); |
|
* possibility to specify own regex-pattern to match epoch date-time, e. g. `^\[{EPOCH}\]` or `^\[{LEPOCH}\]` (gh-2038); |
|
the epoch-pattern similar to `{DATE}` patterns does the capture and cuts out the match of whole pattern from the log-line, |
|
e. g. date-pattern `^\[{LEPOCH}\]\s+:` will match and cut out `[1516469849551000] :` from begin of the log-line. |
|
* badips.py now uses https instead of plain http when requesting badips.com (gh-2057); |
|
* add support for "any" badips.py bancategory, to be able to retrieve IPs from all categories with a desired score (gh-2056); |
|
* Introduced new parameter `padding` for logging within fail2ban-server (default on, excepting SYSLOG): |
|
Usage `logtarget = target[padding=on|off]` |
|
|
|
|
|
ver. 0.10.2 (2018/01/18) - nothing-burns-like-the-cold |
|
----------- |
|
|
|
### Incompatibility list: |
|
* The configuration for jails using banaction `pf` can be incompatible after upgrade, because pf-action uses |
|
anchors now (see `action.d/pf.conf` for more information). If you want use obsolete handling without anchors, |
|
just rewrite it in the `jail.local` by overwrite of `pfctl` parameter, e. g. like `banaction = pf[pfctl="pfctl"]`. |
|
|
|
### Fixes |
|
* Fixed logging to systemd-journal: new logtarget value SYSOUT can be used instead of STDOUT, to avoid |
|
write of the time-stamp, if logging to systemd-journal from foreground mode (gh-1876) |
|
* Fixed recognition of the new date-format on mysqld-auth filter (gh-1639) |
|
* jail.conf: port `imap3` replaced with `imap` everywhere, since imap3 is not a standard port and old rarely |
|
(if ever) used and can missing on some systems (e. g. debian stretch), see gh-1942. |
|
* config/paths-common.conf: added missing initial values (and small normalization in config/paths-*.conf) |
|
in order to avoid errors while interpolating (e. g. starting with systemd-backend), see gh-1955. |
|
* `action.d/pf.conf`: |
|
- fixed syntax error in achnor definition (documentation, see gh-1919); |
|
- enclose ports in braces for multiport jails (see gh-1925); |
|
* `action.d/firewallcmd-ipset.conf`: fixed create of set for ipv6 (missing `family inet6`, gh-1990) |
|
* `filter.d/sshd.conf`: |
|
- extended failregex for modes "extra"/"aggressive": now finds all possible (also future) |
|
forms of "no matching (cipher|mac|MAC|compression method|key exchange method|host key type) found", |
|
see "ssherr.c" for all possible SSH_ERR_..._ALG_MATCH errors (gh-1943, gh-1944); |
|
- fixed failregex in order to avoid banning of legitimate users with multiple public keys (gh-2014, gh-1263); |
|
|
|
### New Features |
|
* datedetector: extended default date-patterns (allows extra space between the date and time stamps); |
|
introduces 2 new format directives (with corresponding %Ex prefix for more precise parsing): |
|
- %k - one- or two-digit number giving the hour of the day (0-23) on a 24-hour clock, |
|
(corresponds %H, but allows space if not zero-padded). |
|
- %l - one- or two-digit number giving the hour of the day (12-11) on a 12-hour clock, |
|
(corresponds %I, but allows space if not zero-padded). |
|
* `filter.d/exim.conf`: added mode `aggressive` to ban flood resp. DDOS-similar failures (gh-1983); |
|
* New Actions: |
|
- `action.d/nginx-block-map.conf` - in order to ban not IP-related tickets via nginx (session blacklisting in |
|
nginx-location with map-file); |
|
|
|
### Enhancements |
|
* jail.conf: extended with new parameter `mode` for the filters supporting it (gh-1988); |
|
* action.d/pf.conf: extended with bulk-unban, command `actionflush` in order to flush all bans at once. |
|
* Introduced new parameters for logging within fail2ban-server (gh-1980). |
|
Usage `logtarget = target[facility=..., datetime=on|off, format="..."]`: |
|
- `facility` - specify syslog facility (default `daemon`, see https://docs.python.org/2/library/logging.handlers.html#sysloghandler |
|
for the list of facilities); |
|
- `datetime` - add date-time to the message (default on, ignored if `format` specified); |
|
- `format` - specify own format how it will be logged, for example for short-log into STDOUT: |
|
`fail2ban-server -f --logtarget 'stdout[format="%(relativeCreated)5d | %(message)s"]' start`; |
|
* Automatically recover or recreate corrupt persistent database (e. g. if failed to open with |
|
'database disk image is malformed'). Fail2ban will create a backup, try to repair the database, |
|
if repair fails - recreate new database (gh-1465, gh-2004). |
|
|
|
|
|
ver. 0.10.1 (2017/10/12) - succeeded-before-friday-the-13th |
|
----------- |
|
|
|
### Fixes |
|
* fix Gentoo init script's shebang to use openrc-run instead of runscript (gh-1891) |
|
* jail "pass2allow-ftp" supply blocktype and returntype parameters to the action (gh-1884) |
|
* avoid using "ANSI_X3.4-1968" as preferred encoding (if missing environment variables |
|
'LANGUAGE', 'LC_ALL', 'LC_CTYPE', and 'LANG', see gh-1587). |
|
* action.d/pf.conf: several fixes for pf-action like anchoring, etc. (see gh-1866, gh-1867); |
|
* fixed ignoreself issue "Retrieving own IPs of localhost failed: inet_pton() argument 2 must be string, not int" (see gh-1865); |
|
* fixed tags `<fq-hostname>` and `<sh-hostname>`, could be used without ticket (a. g. in `actionstart` etc., gh-1859). |
|
|
|
* setup.py: fixed several setup facilities (gh-1874): |
|
- don't check return code by dry-run: returns 256 on some python/setuptool versions; |
|
- `files/fail2ban.service` renamed as template to `files/fail2ban.service.in`; |
|
- setup process generates `build/fail2ban.service` from `files/fail2ban.service.in` using distribution related bin-path; |
|
- bug-fixing by running setup with option `--dry-run`; |
|
|
|
### New Features |
|
* introduced new command-line options `--dp`, `--dump-pretty` to dump the configuration using more |
|
human readable representation (opposite to `-d`); |
|
|
|
### Enhancements |
|
* nftables actions are IPv6-capable now (gh-1893) |
|
* filter.d/dovecot.conf: introduced mode `aggressive` for cases like "disconnected before auth was ready" (gh-1880) |
|
|
|

TODO: implementing of options resp. other tasks from PR #1346 |
|
documentation should be extended (new options, etc) |
|
|
|
### Fixes |
|
* `filter.d/apache-auth.conf`: |
|
- better failure recognition using short form of regex (url/referer are foreign inputs, see gh-1645) |
|
* `filter.d/apache-common.conf` (`filter.d/apache-*.conf`): |
|
- support of apache log-format if logging into syslog/systemd (gh-1695), using parameter `logging`, |
|
parameter usage for jail: |
|
filter = apache-auth[logging=syslog] |
|
parameter usage for `apache-common.local`: |
|
logging = syslog |
|
* `filter.d/pam-generic.conf`: |
|
- [grave] injection on user name to host fixed |
|
* `filter.d/sshd.conf`: |
|
- rewritten using `prefregex` and used MLFID-related multi-line parsing |
|
(by using tag `<F-MLFID>` instead of buffering with `maxlines`); |
|
- optional parameter `mode` rewritten: normal (default), ddos, extra or aggressive (combines all), |
|
see sshd for regex details) |
|
* `filter.d/sendmail-reject.conf`: |
|
- rewritten using `prefregex` and used MLFID-related multi-line parsing; |
|
- optional parameter `mode` introduced: normal (default), extra or aggressive |
|
* `filter.d/haproxy-http-auth`: do not mistake client port for part of an IPv6 address (gh-1745) |
|
* `filter.d/postfix.conf`: |
|
- updated to latest postfix formats |
|
- joined several postfix filter together (normalized and optimized version, gh-1825) |
|
- introduced new parameter `mode` (see gh-1825): more (default, combines normal and rbl), auth, normal, |
|
rbl, ddos, extra or aggressive (combines all) |
|
- postfix postscreen (resp. other RBL's compatibility fix, gh-1764, gh-1825) |
|
* `filter.d/postfix-rbl.conf`: removed (replaced with `postfix[mode=rbl]`) |
|
* `filter.d/postfix-sasl.conf`: removed (replaced with `postfix[mode=auth]`) |
|
* `filter.d/roundcube-auth.conf`: |
|
- fixed regex when `X-Real-IP` or/and `X-Forwarded-For` are present after host (gh-1303); |
|
- fixed regex when logging authentication errors to journal instead to a local file (gh-1159); |
|
- additionally fixed more complex injections on username (e. g. using dot after fake host). |
|
* `filter.d/ejabberd-auth.conf`: fixed failregex - accept new log-format (gh-993) |
|
* `action.d/complain.conf` |
|
- fixed using new tag `<ip-rev>` (sh/dash compliant now) |
|
* `action.d/sendmail-geoip-lines.conf` |
|

|
* fail2ban-regex: fixed matched output by multi-line (buffered) parsing |
|
* fail2ban-regex: support for multi-line debuggex URL implemented (gh-422) |
|
* fixed ipv6-action errors on systems not supporting ipv6 and vice versa (gh-1741) |
|
* fixed directory-based log-rotate for pyinotify-backend (gh-1778) |
|
|
|
### New Features |
|
* New Actions: |
|
|
|
* New Filters: |
|
|
|
### Enhancements |
|
* Introduced new filter option `prefregex` for pre-filtering using single regular expression (gh-1698); |
|
* Many times faster and fewer CPU-hungry because of parsing with `maxlines=1`, so without |
|
line buffering (scrolling of the buffer-window). |
|
Combination of tags `<F-MLFID>` and `<F-NOFAIL>` can be used now to process multi-line logs |
|
using single-line expressions: |
|
- tag `<F-MLFID>`: used to identify resp. store failure info for groups of log-lines with the same |
|
identifier (e. g. combined failure-info for the same conn-id by `<F-MLFID>(?:conn-id)</F-MLFID>`, |
|
see sshd.conf for example); |
|
- tag `<F-MLFFORGET>`: can be used as mark to forget current multi-line MLFID (e. g. by connection |
|
closed, reset or disconnect etc); |
|
- tag `<F-NOFAIL>`: used as mark for no-failure (helper to accumulate common failure-info, |
|
e. g. from lines that contain IP-address); |
|
Opposite to obsolete multi-line parsing (using buffering with `maxlines`) it is more precise and |
|
can recognize multiple failure attempts within the same connection (MLFID). |
|
* Several filters optimized with pre-filtering using new option `prefregex`, and multiline filter |
|
using `<F-MLFID>` + `<F-NOFAIL>` combination; |
|
* Exposes filter group captures in actions (non-recursive interpolation of tags `<F-...>`, |
|
see gh-1698, gh-1110) |
|
* Some filters extended with user name (can be used in gh-1243 to distinguish IP and user, |
|
resp. to remove after success login the user-related failures only); |
|
* Safer, more stable and faster replaceTag interpolation (switched from cycle over all tags |
|
to re.sub with callable) |
|
* substituteRecursiveTags optimization + moved in helpers facilities (because currently used |
|
commonly in server and in client) |
|
* New tags (usable in actions): |
|
- `<fid>` - failure identifier (if raw resp. failures without IP address) |
|
- `<ip-rev>` - PTR reversed representation of IP address |
|
- `<ip-host>` - host name of the IP address |
|
- `<bancount>` - ban count of this offender if known as bad (started by 1 for unknown) |
|
- `<bantime>` - current ban-time of the ticket (prolongation can be retarded up to 10 sec.) |
|
- `<F-...>` - interpolates to the corresponding filter group capture `...` |
|
- `<fq-hostname>` - fully-qualified name of host (the same as `$(hostname -f)`) |
|
- `<sh-hostname>` - short hostname (the same as `$(uname -n)`) |
|
* Introduced new action command `actionprolong` to prolong ban-time (e. g. set new timeout if expected); |
|
Several actions (like ipset, etc.) rewritten using net logic with `actionprolong`. |
|
Note: because ban-time is dynamic, it was removed from jail.conf as timeout argument (check jail.local). |
|
* Allow to use filter options by `fail2ban-regex`, example: |
|
fail2ban-regex text.log "sshd[mode=aggressive]" |
|
* Samples test case factory extended with filter options - dict in JSON to control |
|
filter options (e. g. mode, etc.): |
|
# filterOptions: {"mode": "aggressive"} |
|
* Introduced new jail option "ignoreself", specifies whether the local resp. own IP addresses |
|
should be ignored (default is true). Fail2ban will not ban a host which matches such addresses. |
|
Option "ignoreip" affects additionally to "ignoreself" and don't need to include the DNS |
|
resp. IPs of the host self. |
|
* Regex will be compiled as MULTILINE only if needed (buffering with `maxlines` > 1), that enables: |
|
- to improve performance by the single line parsing (see gh-1733); |
|
- make regex more precise (because distinguish between anchors `^`/`$` for the begin/end of string |
|
and the new-line character '\n', e. g. if coming from filters (like systemd journal) that allow |
|
the parsing of log-entries contain new-line chars (as single entry); |
|
- if multiline regex however expected (by single-line parsing without buffering) - prefix `(?m)` |
|
could be used in regex to enable it; |
|
* Implemented execution of `actionstart` on demand (conditional), if action depends on `family` (gh-1742): |
|
- new action parameter `actionstart_on_demand` (bool) can be set to prevent/allow starting action |
|
on demand (default retrieved automatically, if some conditional parameter `param?family=...` |
|
presents in action properties), see `action.d/pf.conf` for example; |
|
- additionally `actionstop` will be executed only for families previously executing `actionstart` |
|
(starting on demand only) |
|
* Introduced new command `actionflush`: executed in order to flush all bans at once |
|
e. g. by unban all, reload with removing action, stop, shutdown the system (gh-1743), |
|
the actions having `actionflush` do not execute `actionunban` for each single ticket |
|
* Add new command `actionflush` default for several iptables/iptables-ipset actions (and common include); |
|
* Add new jail option `logtimezone` to force the timezone on log lines that don't have an explicit one (gh-1773) |
|
* Implemented zone abbreviations (like CET, CEST, etc.) and abbr+-offset functionality (accept zones |
|
like 'CET+0100'), for the list of abbreviations see strptime.TZ_STR; |
|
* Introduced new option `--timezone` (resp. `--TZ`) for `fail2ban-regex`. |
|
* Tokens `%z` and `%Z` are changed (more precise now); |
|
* Introduced new tokens `%Exz` and `%ExZ` that fully support zone abbreviations and/or offset-based |
|
zones (implemented as enhancement using custom `datepattern`, because may be too dangerous for default |
|
patterns and tokens like `%z`); |
|
Note: the extended tokens supported zone abbreviations, but it can parse 1 or 3-5 char(s) in lowercase. |
|
Don't use them in default date-patterns (if not anchored, few precise resp. optional). |
|
Because python currently does not support mixing of case-sensitive with case-insensitive matching, |
|
the TZ (in uppercase) cannot be combined with `%a`/`%b` etc (that are currently case-insensitive), |
|
to avoid invalid date-time recognition in strings like '11-Aug-2013 03:36:11.372 error ...' with |
|
wrong TZ "error". |
|
Hence `%z` currently match literal Z|UTC|GMT only (and offset-based), and `%Exz` - all zone |
|
abbreviations. |
|
* `filter.d/courier-auth.conf`: support failed logins with method only |
|
* Config reader's: introduced new syntax `%(section/option)s`, in opposite to extended interpolation of |
|
python 3 `${section:option}` work with all supported python version in fail2ban and this syntax is |
|
like our another features like `%(known/option)s`, etc. (gh-1750) |
|
* Variable `default_backend` switched to `%(default/backend)s`, so totally backwards compatible now, |
|
but now the setting of parameter `backend` in default section of `jail.local` can overwrite default |
|
backend also (see gh-1750). In the future versions parameter `default_backend` can be removed (incompatibility, |
|
possibly some distributions affected). |

|
ver. 0.10.0-alpha-1 (2016/07/14) - ipv6-support-etc |
|
----------- |
|
|
|
### Fixes |
|
* [Grave] memory leak's fixed (gh-1277, gh-1234) |
|
* [Grave] Misleading date patterns defined more precisely (using extended syntax |
|
`%Ex[mdHMS]` for exact two-digit match or e. g. `%ExY` as more precise year |
|
pattern, within same century of last year and the next 3 years) |
|
* [Grave] extends date detector template with distance (position of match in |
|
log-line), to prevent grave collision using (re)ordered template list (e.g. |
|
find-spot of wrong date-match inside foreign input, misleading date patterns |
|
by ambiguous formats, etc.) |
|
* Distance collision check always prefers template with shortest distance |
|
(left for right) if date pattern is not anchored |
|
* Tricky bug fix: last position of log file will be never retrieved (gh-795), |
|
because of CASCADE all log entries will be deleted from logs table together with jail, |
|
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) |
|
* testExecuteTimeoutWithNastyChildren: sporadical bug repaired - wait for pid file inside bash, |
|
kill tree in any case (gh-1155) |
|
* purge database will be executed now (within observer). |
|
* restoring currently banned ip after service restart fixed |
|
(now < timeofban + bantime), ignore old log failures (already banned) |
|
* Fixed high-load of pyinotify-backend, |
|
see https://github.com/fail2ban/fail2ban/issues/885#issuecomment-248964591 |
|
* Database: stability fix - repack cursor iterator as long as locked |
|
* File filter backends: stability fix for sporadically errors - always close file |
|
handle, otherwise may be locked (prevent log-rotate, etc.) |
|
* Pyinotify-backend: stability fix for sporadically errors in multi-threaded |
|
environment (without lock) |
|
* Fixed sporadically error in testCymruInfoNxdomain, because of unsorted values |
|
* Misleading errors logged from ignorecommand in success case on retcode 1 (gh-1194) |
|
* fail2ban.service - systemd service updated (gh-1618): |
|
- starting service in normal mode (without forking) |
|
- does not restart if service exited normally (exit-code 0, e.g. stopped via fail2ban-client) |
|
- does not restart if service can not start (exit-code 255, e.g. wrong configuration, etc.) |
|
- service can be additionally started/stopped with commands (fail2ban-client, fail2ban-server) |
|
- automatically creates `/var/run/fail2ban` directory before start fail2ban |
|
(systems with virtual resp. memory-based FS for `/var/run`), see gh-1531 |
|
- if fail2ban running as systemd-service, for logging to the systemd-journal, |
|
the `logtarget` could be set to STDOUT |
|
- value `logtarget` for system targets allowed also in lowercase (stdout, stderr, syslog, etc.) |
|
* Fixed UTC/GMT named time zone, using `%Z` and `%z` patterns |
|
(special case with 0 zone offset, see gh-1575) |
|
* `filter.d/freeswitch.conf` |
|
- Optional prefixes (server, daemon, dual time) if systemd daemon logs used (gh-1548) |
|
- User part rewritten to accept IPv6 resp. domain after "@" (gh-1548) |
|
|
|
### New Features |
|
* IPv6 support: |
|
- IP addresses are now handled as objects rather than strings capable for |
|
handling both address types IPv4 and IPv6 |
|
- iptables related actions have been amended to support IPv6 specific actions |
|
additionally |
|
- hostsdeny and route actions have been tested to be aware of v4 and v6 already |
|
- pf action for *BSD systems has been improved and supports now also v4 and v6 |
|
- name resolution is now working for either address type |
|
- new conditional section functionality used in config resp. includes: |
|
- [Init?family=inet4] - IPv4 qualified hosts only |
|
- [Init?family=inet6] - IPv6 qualified hosts only |
|
* Increment ban time (+ observer) functionality introduced. |
|
Thanks Serg G. Brester (sebres) |
|
* Database functionality extended with bad ips. |
|
* New reload functionality (now totally without restart, unbanning/rebanning, etc.), |
|
see gh-1557 |
|
* Several commands extended and new commands introduced: |
|
- `restart [--unban] [--if-exists] <JAIL>` - restarts the jail \<JAIL\> |
|
(alias for `reload --restart ... <JAIL>`) |
|
- `reload [--restart] [--unban] [--all]` - reloads the configuration without restarting |
|
of the server, the option `--restart` activates completely restarting of affected jails, |
|
thereby can unban IP addresses (if option `--unban` specified) |
|
- `reload [--restart] [--unban] [--if-exists] <JAIL>` - reloads the jail \<JAIL\>, |
|
or restarts it (if option `--restart` specified), at the same time unbans all IP addresses |
|
banned in this jail, if option `--unban` specified |
|
- `unban --all` - unbans all IP addresses (in all jails and database) |
|
- `unban <IP> ... <IP>` - unbans \<IP\> (in all jails and database) (see gh-1388) |
|
- introduced new option `-t` or `--test` to test configuration resp. start server only |
|
if configuration is clean (fails by wrong configured jails if option `-t` specified) |
|
* New command action parameter `actionrepair` - command executed in order to restore |
|
sane environment in error case of `actioncheck`. |
|
* Reporting via abuseipdb.com: |
|
- Bans can now be reported to abuseipdb |
|
- Categories must be set in the config |
|
- Relevant log lines included in report |
|
|
|
### Enhancements |
|
* Huge increasing of fail2ban performance and especially test-cases performance (see gh-1109) |
|
* Datedetector: in-place reordering using hits and last used time: |
|
matchTime, template list etc. rewritten because of performance degradation |
|
* Prevent out of memory situation if many IP's makes extremely many failures (maxEntries) |
|
* Introduced string to seconds (str2seconds) for configuration entries with time, |
|
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) |
|
* Ticket and some other modules prepared to easy merge with newest version of 'ban-time-incr' |
|
* 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`) |
|
- `-g`, `--no-gamin` to prevent running of tests that require the gamin (slow) |
|
- `-m`, `--memory-db` - run database tests using memory instead of file |
|
- `-i`, `--ignore` - negate [regexps] filter to ignore tests matched specified regexps |
|
* Background servicing: prevents memory leak on some platforms/python versions, using forced GC |
|
in periodic intervals (latency and threshold) |
|
* executeCmd partially moved from action to new module utils |
|
* Several functionality of class `DNSUtils` moved to new class `IPAddr`, |
|
both classes moved to new module `ipdns` |
|
* Pseudo-conditional section introduced, for conditional substitution resp. |
|
evaluation of parameters for different family qualified hosts, |
|
syntax `[Section?family=inet6]` (currently use for IPv6-support only). |
|
* All the backends were rewritten to get reload-possibility, performance increased, |
|
so fewer greedy regarding cpu- resp. system-load now |
|
* Numeric log-level allowed now in server (resp. fail2ban.conf); |
|
* Implemented better error handling in some multi-threaded routines; shutdown of jails |
|
rewritten (faster and safer, does not breaks shutdown process if some error occurred) |
|
* Possibility for overwriting some configuration options (read with config-readers) |
|
with command line option, e. g.: |
|
```bash |
|
## start server with DEBUG log-level (ignore level read from fail2ban.conf): |
|
fail2ban-client --loglevel DEBUG start |
|
## or |
|
fail2ban-server -c /cfg/path --loglevel DEBUG start |
|
## keep server log-level by reload (without restart it) |
|
fail2ban-client --loglevel DEBUG reload |
|
## switch log-level back to INFO: |
|
fail2ban-client set loglevel INFO |
|
``` |
|
* Optimized BanManager: increase performance, fewer system load, try to prevent |
|
memory leakage: |
|
- better ban/unban handling within actions (e.g. used dict instead of list) |
|
- don't copy bans resp. its list on some operations; |
|
- added new unbantime handling to relieve unBanList (prevent permanent |
|
searching for tickets to unban) |
|
- prefer failure-ID as identifier of the ticket to its IP (most of the time |
|
the same, but it can be something else e.g. user name in some complex jails, |
|
as introduced in 0.10) |
|
* Regexp enhancements: |
|
- build replacement of `<HOST>` substitution corresponding parameter |
|
`usedns` - dns-part will be added only if `usedns` is not `no`, |
|
also using fail2ban-regex |
|
- new replacement for `<ADDR>` in opposition to `<HOST>`, for separate |
|
usage of 2 address groups only (regardless of `usedns`), `ip4` and `ip6` |
|
together, without host (dns) |
|
* Misconfigured jails don't prevent fail2ban from starting, server starts |
|
nevertheless, as long as one jail was successful configured (gh-1619) |
|
Message about wrong jail configuration logged in client log (stdout, systemd |
|
journal etc.) and in server log with error level |
|
* More precise date template handling (WARNING: theoretically possible incompatibilities): |
|
- datedetector rewritten more strict as earlier; |
|
- default templates can be specified exacter using prefix/suffix syntax (via `datepattern`); |
|
- more as one date pattern can be specified using option `datepattern` now |
|
(new-line separated); |
|
- some default options like `datepattern` can be specified directly in |
|
section `[Definition]`, that avoids contrary usage of unnecessarily `[Init]` |
|
section, because of performance (each extra section costs time); |
|
- option `datepattern` can be specified in jail also (e. g. jails without filters |
|
or custom log-format, new-line separated for multiple patterns); |
|
- if first unnamed group specified in pattern, only this will be cut out from |
|
search log-line (e. g.: `^date:[({DATE})]` will cut out only datetime match |
|
pattern, and leaves `date:[] ...` for searching in filter); |
|
- faster match and fewer searching of appropriate templates |
|
(DateDetector.matchTime calls rarer DateTemplate.matchDate now); |
|
- several standard filters extended with exact prefixed or anchored date templates; |
|
* Added possibility to recognize restored state of the tickets (see gh-1669). |
|
New option `norestored` introduced, to ignore restored tickets (after restart). |
|
To avoid execution of ban/unban for the restored tickets, `norestored = true` |
|
could be added in definition section of action. |
|
For conditional usage in the shell-based actions an interpolation `<restored>` |
|
could be used also. E. g. it is enough to add following script-piece at begin |
|
of `actionban` (or `actionunban`) to prevent execution: |
|
`if [ '<restored>' = '1' ]; then exit 0; fi;` |
|
Several actions extended now using `norestored` option: |
|
- complain.conf |
|
- dshield.conf |
|
- mail-buffered.conf |
|
- mail-whois-lines.conf |
|
- mail-whois.conf |
|
- mail.conf |
|
- sendmail-buffered.conf |
|
- sendmail-geoip-lines.conf |
|
- sendmail-whois-ipjailmatches.conf |
|
- sendmail-whois-ipmatches.conf |
|
- sendmail-whois-lines.conf |
|
- sendmail-whois-matches.conf |
|
- sendmail-whois.conf |
|
- sendmail.conf |
|
- smtp.py |
|
- xarf-login-attack.conf |
|
* fail2ban-testcases: |
|
- `assertLogged` extended with parameter wait (to wait up to specified timeout, |
|
before we throw assert exception) + test cases rewritten using that |
|
- added `assertDictEqual` for compatibility to early python versions (< 2.7); |
|
- new `with_foreground_server_thread` decorator to test several client/server commands |
|
|
|

|
----------- |
|
|
|
### Fixes |
|
* 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 |

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

|
* Introduced new log-level `MSG` (as INFO-2, equivalent to 18) |
|
|
|
|
|
ver. 0.9.6 (2016/12/10) - stretch-is-coming |
|
----------- |
|
|
|
### Fixes |
|
* 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` |
|

|
* `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 Features |
|
* 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) |
|
|
|
### Enhancements |
|
* 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 |
|
----------- |
|
|
|
### Fixes |
|
* `filter.d/monit.conf` |
|
- Extended failregex with new monit "access denied" version (gh-1355) |
|
- failregex of previous monit version merged as single expression |
|
* `filter.d/postfix.conf`, `filter.d/postfix-sasl.conf` |
|
- Extended failregex daemon part, matching also `postfix/smtps/smtpd` |
|
now (gh-1391) |
|
* Fixed a grave bug within tags substitutions because of incorrect |
|
detection of recursion in case of multiple inline substitutions |
|
of the same tag (affected actions: `bsd-ipfw`, etc). Now tracks |
|
the actual list of the already substituted tags (per tag instead |
|
of single list) |
|
* `filter.d/common.conf` |
|
- Unexpected extra regex-space in generic `__prefix_line` (gh-1405) |
|
- All optional spaces normalized in `common.conf`, test covered now |
|
- Generic `__prefix_line` extended with optional brackets for the |
|
date ambit (gh-1421), added new parameter `__date_ambit` |
|
* `gentoo-initd` fixed `--pidfile` bug: `--pidfile` is option of |
|
`start-stop-daemon`, not argument of fail2ban (see gh-1434) |
|
* `filter.d/asterisk.conf` |
|
- Fixed security log support for PJSIP and Asterisk 13+ (gh-1456) |
|
- Improved log support for PJSIP and Asterisk 13+ with different |
|
callID (gh-1458) |
|
|
|
### New Features |
|
* New Actions: |
|
- `action.d/firewallcmd-rich-rules` and `action.d/firewallcmd-rich-logging` |
|
(gh-1367) |
|
* New filters: |
|
- slapd - ban hosts, that were failed to connect with invalid |
|
credentials: error code 49 (gh-1478) |
|
|
|
|
|
### Enhancements |
|
* Extreme speedup of all sqlite database operations (gh-1436), |
|
by using of following sqlite options: |
|
- (synchronous = OFF) write data through OS without syncing |
|
- (journal_mode = MEMORY) use memory for the transaction logging |
|
- (temp_store = MEMORY) temporary tables and indices are kept in memory |
|
* journald journalmatch for pure-ftpd (gh-1362) |
|
* Added additional regex filter for dovecot ldap authentication failures (gh-1370) |
|
* `filter.d/exim*conf` |
|
- Added additional regexes (gh-1371) |
|
- Made port entry optional |
|
|
|
|
|
ver. 0.9.4 (2016/03/08) - for-you-ladies |
|
----------- |
|
|
|
### Fixes |
|
* `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 `+` |
|
* `filter.d/mysqld-auth.conf` |
|
- 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 |
|
* Treat failed and killed execution of commands identically (only |
|
different log messages), which addresses different behavior on different |
|
exit codes of dash and bash (gh-1155) |
|
* Fix jail.conf.5 man's section (gh-1226) |
|
* Fixed default banaction for allports jails like pam-generic, recidive, etc |
|
with new default variable `banaction_allports` (gh-1216) |
|
* Fixed `fail2ban-regex` stops working on invalid (wrong encoded) character |
|
for python version < 3.x (gh-1248) |
|
* Use postfix_log logpath for postfix-rbl jail |
|
* `filters.d/postfix.conf` - add 'Sender address rejected: Domain not found' failregex |
|
* use `fail2ban_agent` as user-agent in actions badips, blocklist_de, etc (gh-1271) |
|
* Fix ignoring the sender option by action_mw, action_mwl and action_c_mwl |
|
* Changed `filter.d/asterisk` regex for "Call from ..." (few vulnerable now) |
|
* Removed compression and rotation count from logrotate (inherit them from |
|
the global logrotate config) |
|
|
|
### 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. |
|
* New filters: |
|
- `openhab` - domotic software authentication failure with the |
|
rest api and web interface (gh-1223) |
|
- `nginx-limit-req` - ban hosts, that were failed through nginx by limit |
|
request processing rate (ngx_http_limit_req_module) |
|
- `murmur` - ban hosts that repeatedly attempt to connect to |
|
murmur/mumble-server with an invalid server password or certificate. |
|
- `haproxy-http-auth` - filter to match failed HTTP Authentications against a |
|
HAProxy server |
|
* New jails: |
|
- `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 |
|
* Added new date pattern with year after day (e.g. `Sun Jan 23 2005 21:59:59`) |
|
http://bugs.debian.org/798923 |
|
* Added openSUSE path configuration (Thanks Johannes Weberhofer) |
|
* Allow to split ignoreip entries by ',' as well as by ' ' (gh-1197) |
|
* Added a timeout (3 sec) to urlopen within badips.py action |
|
(Thanks M. Maraun) |
|
* Added check against atacker's Googlebot PTR fake records |
|
(Thanks Pablo Rodriguez Fernandez) |
|
* Enhance filter against atacker's Googlebot PTR fake records |
|
(gh-1226) |
|
* Nginx log paths extended (prefixed with "*" wildcard) (gh-1237) |
|
* Added filter for openhab domotic software authentication failure with the |
|
rest api and web interface (gh-1223) |
|
* Add `*_backend` options for services to allow distros to set the default |
|
backend per service, set default to systemd for Fedora as appropriate |
|
* Performance improvements while monitoring large number of files (gh-1265). |
|
Use associative array (dict) for monitored log files to speed up lookup |
|
operations. Thanks @kshetragia |
|
* Specified that fail2ban is PartOf iptables.service `firewalld.service` in |
|
`.service` file -- would reload fail2ban if those services are restarted |
|
* Provides new default `fail2ban_version` and interpolation variable |
|
`fail2ban_agent` in jail.conf |
|
* Enhance filter 'postfix' to ban incoming SMTP client with no fqdn hostname, |
|
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 (superseding 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 |
|
|
|
|
|
ver. 0.9.2 (2015/04/29) - better-quick-now-than-later |
|
---------- |
|
|
|
### Fixes |
|
* Fix ufw action commands |
|
* infinite busy loop on _escapedTags match in substituteRecursiveTags gh-907. |
|
Thanks TonyThompson |
|
* port[s] typo in jail.conf/nginx-http-auth gh-913. Thanks Frederik Wagner |
|
(fnerdwq) |
|
* $ 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 |
|
* New filters: |
|
- postfix-rbl Thanks Lee Clemens |
|
- apache-fakegooglebot.conf Thanks Lee Clemens |
|
- nginx-botsearch Thanks Frantisek Sumsal |
|
- drupal-auth Thanks Lee Clemens |
|
* New recursive embedded substitution feature added: |
|
- `<<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) |
|
|
|
|
|
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 |
|

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 #410077. Also it would now capture and include stdout and stderr |
|
into logging messages in case of error or at DEBUG loglevel. |
|
* Added action xarf-login-attack to report formatted attack messages |
|
according to the XARF standard (v0.2). Close gh-105 |
|
* Support PyPy |
|
* Add filter for apache-botsearch |
|
* Add filter for kerio. Thanks Tony Lawrence for blog of regexs and |
|
providing samples. Close gh-120 |

|
* Custom date formats (strptime) can now be set in filters and jail.conf |
|
* Python based actions can now be created. |
|
- SMTP action for sending emails on jail start, stop and ban. |
|
* Added action to use badips.com reporting and blacklist |
|
- Requires Python 2.7+ |
|
|
|
### Enhancements |
|
* Fail2ban-regex - don't accumulate lines if not printing them. |
|
add options to suppress output of missed/ignored lines. Close gh-644 |
|
* Asterisk now supports syslog format |
|
* Jail names increased to 26 characters and iptables prefix reduced |
|
from fail2ban- to f2b- as suggested by buanzo in gh-462. |
|
* Multiline filter for sendmail-spam. Close gh-418 |
|
* Multiline regex for Disconnecting: Too many authentication failures for |
|
root [preauth]\nConnection closed by 6X.XXX.XXX.XXX [preauth] |
|
* Multiline regex for Disconnecting: Connection from 61.XX.XX.XX port |
|
51353\nToo many authentication failures for root [preauth]. Thanks |
|
Helmut Grohne. Close gh-457 |
|
* Replacing use of deprecated API (.warning, .assertEqual, etc) |
|
* [..a648cc2] Filters can have options now too which are substituted into |
|
failregex / ignoreregex |
|
* [..e019ab7] Multiple instances of the same action are allowed in the |
|
same jail -- use actname option to disambiguate. |
|
* Add honeypot email address to exim-spam filter as argument |
|
* Properties and methods of actions accessible from fail2ban-client |
|
- Use of properties replaces command actions "cinfo" interface |

ver. 0.8.11 (2013/11/13) - loves-unittests-and-tight-DoS-free-filter-regexes |
|
---------- |
|
|
|
In light of CVE-2013-2178 that triggered our last release we have put |
|
a significant effort into tightening all of the regexs of our filters |
|
to avoid another similar vulnerability. All filters have been updated |
|
and some to catch more login/authentication failures and to support |
|
for newer application versions. There are test cases for most log |
|
cases of failures now. |
|
|
|
As usual, if you have other examples that demonstrate that a filter is |
|
insufficient, or if we have inadvertently introduced a regression, |
|
please provide us with example log lines on the github issue tracker |
|
http://github.com/fail2ban/fail2ban/issues and NOT on a random blog in |
|
some obscure corner of the Internet. |
|
|
|
Many thanks to our contributors for this release Daniel Black, Yaroslav |
|
Halchenko, Steven Hiscocks, Mark McKinstry, Andy Fragen, Orion Poplawski, |
|
Alexander Dietrich, JP Espinosa, Jamyn Shanley, Beau Raines, François |
|
Boulogne and others who have helped on IRC and mailing list, logged issues |
|
and bug requests. |
|
|
|
### IMPORTANT incompatible changes |
|
|
|
Filter name changes: |
|
* 'lighttpd-fastcgi' filter has been renamed to 'suhosin' |
|
* 'sasl' has been renamed to 'postfix-sasl' |
|
* 'exim' spam catching failregexes was split out into 'exim-spam' |
|
These changes will require changing jail.{conf,local} if any of |
|
those filters were used. |
|
|
|
### Fixes |
|
- Jonathan Lanning |
|
* `filter.d/asterisk` -- identified another regex for blocking. Also channel |
|
ID is hex not decimal as noted in sample logs provided. |
|
- Daniel Black & Marcel Dopita |
|
* `filter.d/apache-auth` -- fixed and apache auth samples provide. Closes gh-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 & Georgiy Mernov & ftoppi & Мернов Георгий |
|
* `filter.d/exim.conf` -- regex hardening and extra failure examples in |
|

|
- Daniel Black & Sebastian Arcus |
|
* `filter.d/asterisk` -- more regexes |
|
- Daniel Black |
|
* `action.d/hostsdeny` -- NOTE: new dependency '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. |
|
* `action.d/bsd-ipfw` - action option unused. Change blocktype to port unreach |
|
instead of deny for consistency. |
|
* `filter.d/dovecot` - added to support different dovecot failure |
|
"..disallowed plaintext auth". Closes Debian bug #709324 |
|
* `filter.d/roundcube-auth` - timezone offset can be positive or negative |
|
* `action.d/bsd-ipfw` - action option unused. Fixed to blocktype for |
|
consistency. default to port unreach instead of deny |
|
* `filter.d/dropbear` - fix regexs to match standard dropbear and the patched |
|
http://www.unchartedbackwaters.co.uk/files/dropbear/dropbear-0.52.patch |
|
and add PAM is it in dropbear-2013.60 source code. |
|
* `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/mysqld-auth.conf` - mysql can use syslog |
|
* `filter.d/sshd` - regex enhancements to support openssh-6.3. Closes Debian |
|
bug #722970. Thanks Colin Watson for the regex analysis. |
|
* `filter.d/wuftpd` - regex enhancements to support pam and wuftpd. Closes |
|
Debian bug #665925 |
|
- 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 |
|

|
regular expressions with the -D parameter. |
|

|
* `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 |
|
* `filter.d/nginx-http-auth` -- filter added for http basic authentication |

|
asterisk-udp. Users should replace existing jails with asterisk to |

|
syslog |
|
* `filter.d/qmail` - rewrote regex to anchor at start. Added regex for |
|
another "in the wild" patch to rblsmtp. |
|
- 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 |
|

|
enabled jail. Closes gh-63 |
|
* `<HOST>` is now enforced to end with an alphanumeric |
|

|
* date matching - for standard asctime formats prefer more detailed |
|
first (thus use year if available) |
|

|
regenerated to get updated (although now still an old) list of |
|
"bad" bots |

|
* `filter.d/postfix` - add filter for VRFY failures. Closes gh-322. |
|
- Orion Poplawski |
|
* `fail2ban.d/` and `jail.d/` directories are added to `etc/fail2ban` to facilitate |
|
their use |

### Fixes |
|
- Yaroslav Halchenko |
|
* [6ccd5781] `filter.d/apache-{auth,nohome,noscript,overflows`} - anchor |

|
---------- |
|
- Almost a complete rewrite :) Fail2ban design is really better (IMHO). There is |
|
a lot of new features |
|
- Client/Server architecture |
|
- Multithreading. Each jail has its own threads: one for the log reading and |
|
another for the actions |
|
- Execute several actions |
|
- Split configuration files. They are more readable and easy to use |
|
- failregex uses group (<host>) now. This feature was already present in the |
|
Debian package |
|
- lots of things... |
|
|
|
ver. 0.6.1 (2006/03/16) - stable |

|

|
Börjesson |
|
- Removed 192.168.0.0/16 from ignoreip. Attacks could also come from the local |
|
network. |
|
- Robust startup: if iptables module does not get fully initialized after |
|
startup of fail2ban, fail2ban will do "maxreinit" attempts to initialize its |
|
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 |
|
- Added initial support for hosts.deny and shorewall. Need more testing. Please |
|
test. Thanks to kojiro from Gentoo forum for hosts.deny support |
|

|
further adjusted by upstream author). |
|
* Added -f command line parameter for [findtime]. |
|
* Added a cleanup of firewall rules on emergency shutdown when unknown |
|
exception is caught. |
|
* Fail2ban should not crash now if a wrong file name is specified in config. |
|

|
and then only loglevel (verbose, debug) is processed, so the warning could |
|
be seen in the logs |
|
* Added a keyword `<section>` in parsing of the subject and the body of an email |
|
sent out by fail2ban (closes: #330311) |
|

|
