Yaroslav Halchenko 31a1560eaa minor typos (thanks Vincent Lefevre, Debian #847785) 2016-12-11 15:13:11 -05:00
sebres ae7297e16b more precise date template handling (WARNING: this commit creates 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 (jails without filters);
  - if first group specified, only this will be cut out from search log-line (e. g.: `^date:[({DATE})]` will cut out only datetime match pattern, and leaves `date:[] failure ip...` for searching in filter);
  - faster match and fewer searching of appropriate templates (DateDetector.matchTime calls rarer DateTemplate.matchDate now);
  - standard filters extended with exact prefixed or anchored date templates;

template cache introduced (in opposition to default template cache, holds custom templates cached by pattern for possible common usage of same template/regex);

sebres ab0ac2111c added possibility to specify more precise default date pattern:
- `datepattern = {^LN-BEG}` - only line-begin anchored default patterns
     (matches date only at begin of line, or with max distance up to 2 non-alphanumeric characters from line-begin);
  - `datepattern = {*WD-BEG}` - only word-begin anchored default patterns;
  - `datepattern = ^prefix{DATE}suffix` - exact specified default patterns (using prefix and suffix);
common filter configs gets a more precise, line-begin anchored (datepattern = {^LN-BEG}) resp. custom anchoring default date-patterns;

rhardy613 66fe5a77ce Fix ASSP filter to work with both ASSP V1 and V2
ASSP V1 development stopped at the end of 2014 and it is now deprecated.
All users were urged to upgrade to ASSP V2 which is still actively
developed.
fail2ban 0.9.5 (and trunk) still have code which only understands ASSP
V1 logs.
This means the filter ignores brute force attacks against ASSP. This fix
adds V2 support.

rhardy613 890a3dcbb9 Fix ASSP filter to work with current release of ASSP
ASSP V1 development stopped at the end of 2014 and it is now deprecated.
All users were urged to upgrade to ASSP V2 which is still actively
developed. For some reason fail2ban 0.9.5 (and trunk) still have code
which only understands ASSP V1 logs. This means the filter ignores brute
force attacks against ASSP.
Now updated with anchored patterns tested against 6 months of log data.
