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 -

Long delayed 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) -

What aught to be a bugfix release delayed into a featured release 0.9.1 ver. 0.9.1 (2014/10/29) - better, faster, stronger ---------- - Refactoring (IMPORTANT -- Please review your setup and configuration): * iptables-common.conf replaced iptables-blocktype.conf (iptables-blocktype.local should still be read) and now also provides defaults for the chain, port, protocol and name tags - Fixes: * start of file2ban aborted (on slow hosts, systemd considers the server has been timed out and kills him), see gh-824 * UTF-8 fixes in pure-ftp thanks to Johannes Weberhofer. Closes gh-806. * systemd backend error on bad utf-8 in python3 * badips.py action error when logging HTTP error raised with badips request * fail2ban-regex failed to work in python3 due to space/tab mix * recidive regex samples incorrect log level * journalmatch for recidive incorrect PRIORITY * loglevel couldn't be changed in fail2ban.conf * Handle case when no sqlite library is available for persistent database * Only reban once per IP from database on fail2ban restart * Nginx filter to support missing server_name.
