Fail2Ban: Changelog
|
|
===================
|
|
|
|
Incompatibility list (compared 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 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 uses more precise date template handling, that can be theoretically incompatible to some
|
|
user configurations resp. `datepattern`.
|
|
|
|
* Since v0.10 fail2ban supports the matching of the IPv6 addresses, but not all ban actions are
|
|
IPv6-capable now.
|
|
|
|
|
|
ver. 0.10.2-dev-1 (2017/??/??) - development edition
|
|
-----------
|
|
|
|
### Incompatibility list:
|
|
* The configuration for multiport jails using banaction `pf` can be incompatible after upgrade, if
|
|
ports are enclosed in curly braces `{ }` in the `jail.local` etc. This may cause a double-brackets now.
|
|
|
|
### Fixes
|
|
* action.d/pf.conf:
|
|
- fixed syntax error in achnor definition (documentation, see gh-1919);
|
|
- enclose ports in braces for multiport jails (see gh-1925);
|
|
|
|
### New Features

|
|
|
### Enhancements
|
|
|
|
|
|
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 ignorself 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)
|
|
|
|
|
|
ver. 0.10.0 (2017/08/09) - long-awaited 0.10th version
|
|
-----------
|
|
|
|
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`:

|
|
(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 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
|
|
- `<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)`)
|
|
* 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)
|
|
* 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
|
|
* 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
|
|
- Catagories 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
|
|
|
|
|
|
ver. 0.9.8 (2016/XX/XXX) - wanna-be-released
|
|
-----------
|
|

|
|
- Fixed non-anchored part of failregex (misleading match of colon inside

|
|
|
|
|
|
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:)

|
|
with wrong python version (gh-1506)

|
|
* 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 (superseeding LC_TIME) to override
|
|
locale on systems with customized LC_ALL
|
|
* performance fix: minimizes connection overhead, close socket only at
|
|
communication end (gh-1099)
|
|
* unbanip always deletes ip from database (independent of bantime, also if
|
|
currently not banned or persistent)
|
|
* guarantee order of dbfile to be before dbpurgeage (gh-1048)
|
|
* always set 'dbfile' before other database options (gh-1050)
|
|
* kill the entire process group of the child process upon timeout (gh-1129).
|
|
Otherwise could lead to resource exhaustion due to hanging whois
|
|
processes.
|
|
* resolve `/var/run/fail2ban` path in setup.py to help installation
|
|
on platforms with `/var/run` -> /run symlink (gh-1142)
|
|
|
|
### New Features
|
|
* RETURN iptables target is now a variable: `<returntype>`
|
|
* New type of operation: pass2allow, use fail2ban for "knocking",
|
|
opening a closed port by swapping blocktype and returntype
|
|
* New filters:
|
|
- froxlor-auth - Thanks Joern Muehlencord
|
|
- apache-pass - filter Apache access log for successful authentication
|
|
* New actions:
|
|
- shorewall-ipset-proto6 - using proto feature of the Shorewall. Still requires
|
|
manual pre-configuration of the shorewall. See the action file for detail.
|
|
* New jails:
|
|
- pass2allow-ftp - allows FTP traffic after successful HTTP authentication
|
|
|
|
### Enhancements
|
|
* `action.d/cloudflare.conf` - improved documentation on how to allow
|
|
multiple CF accounts, and jail.conf got new compound action
|
|
definition action_cf_mwl to submit cloudflare report.
|
|
* Check access to socket for more detailed logging on error (gh-595)
|
|
* fail2ban-testcases man page
|
|
* `filter.d/apache-badbots.conf`, `filter.d/nginx-botsearch.conf` - add
|
|
HEAD method verb
|
|
* Revamp of Travis and coverage automated testing
|
|
* Added a space between IP address and the following colon
|
|
in notification emails for easier text selection
|
|
* Character detection heuristics for whois output via optional setting
|
|
in mail-whois*.conf. Thanks Thomas Mayer.
|
|
Not enabled by default, if _whois_command is set to be
|
|
%(_whois_convert_charset)s (e.g. in `action.d/mail-whois-common.local`),
|
|
it
|
|
- detects character set of whois output (which is undefined by
|
|
RFC 3912) via heuristics of the file command
|
|
- converts whois data to UTF-8 character set with iconv
|
|
- sends the whois output in UTF-8 character set to mail program
|
|
- avoids that heirloom mailx creates binary attachment for input with
|
|
unknown character set
|
|
|
|
|
|
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

|
|
multiline regex
|
|

|
|
http://bugs.python.org/issue21207
|
|

|
|
* Recursive action tags now fully processed. Fixes issue with bsd-ipfw
|
|
action
|
|
* Fixed TypeError with "ipfailures" and "ipjailfailures" action tags.
|
|
Thanks Serg G. Brester
|
|
* Correct times for non-timezone date times formats during DST
|
|
* Pass a copy of, not original, aInfo into actions to avoid side-effects
|
|
* Per-distribution paths to the exim's main log
|
|
* Ignored IPs are no longer banned when being restored from persistent
|
|
database
|
|
* Manually unbanned IPs are now removed from persistent database, such they
|
|
wont be banned again when Fail2Ban is restarted
|
|
* Pass "bantime" parameter to the actions in default jail's action
|
|
definition(s)
|
|
* `filters.d/sieve.conf` - fixed typo in _daemon. Thanks Jisoo Park
|
|
* cyrus-imap -- also catch also failed logins via secured (imaps/pop3s).

|
|
- monit Thanks Jason H Martin
|
|
- directadmin Thanks niorg

|
|
- symbiosis-blacklist-allports for Bytemark symbiosis firewall
|
|
- fail2ban-client can fetch the running server version
|
|

|
|
|
|
### Enhancements
|

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:

|
|
- 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

|
* 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
|

|
|
add options to suppress output of missed/ignored lines. Close gh-644
|

|
|
* Multiline filter for sendmail-spam. Close gh-418
|
|

|
* 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

|
|
----------
|
|
|
|
- IMPORTANT incompatible changes:
|
|
- Rename firewall-cmd-direct-new to firewallcmd-new to fit within jail name
|
|
name length. As per gh-395
|
|
- mysqld-syslog-iptables jailname was too long. Renamed to mysqld-syslog.
|
|
Part of gh-447.
|
|
|
|
### Fixes

|
|
a specific jail in nagios script.
|
|
- Filter dovecot reordered session and TLS items in regex with wider scope
|
|
for session characters. Thanks Ivo Truxa. Closes gh-586
|
|

|
|
fail2ban from starting. Thanks Tomasz Ciolek. Closes gh-585.
|
|
|

|
- long names on jails documented based on iptables limit of 30 less
|
|
len("fail2ban-").

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

----------
|
|
- 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
|
|

|
|
test. Thanks to kojiro from Gentoo forum for hosts.deny support

|
|
be seen in the logs

|
|
sent out by fail2ban (closes: #330311)
