* commit '0.8.6-69-gb4099da': (57 commits) DOC: Adjusted header for config/*.conf to mention .local and way to comment Fixed addBannedIP to add enough failures to trigger a ban, rather than just one failure. Fix Gentoo initd script (drop extra_commands) ENH: catch failed ssh logins due to being listed in DenyUsers. Close gh-47 (Closes: #669063) DOC: comment in jail.conf for the need of multiple jails for asterisk Add the INCLUDE section to use __pid_re feature Disable asterisk jail by default Change jail for asterisk, add support for SIP and SIP-TLS on TCP and UDP ports Change NOTICE by NOTICE%(__pid_re)s Added a warning for the recidive jail BF: fail2ban-regex -- adding forgotten char for -v Remove custom bantime Add sample log file for asterisk Add $ at the end of the failregex ENH: fail2ban-regex -- quieter by default and added --verbose mode ENH: minor, just pythonized some parts of fail2ban-regex summary ENH: rudimentary __repr__ for Filter and Jail + moved usedns into set method BF: allow trailing whitespace in few missing it regexes for sshd.conf BF+ENH: added %m-%d-%Y pattern + do not add %Y for Feb 29 fix if already present in the pattern minor comment into TODO ...
