Merge pull request #2205 from benrubson/patch-1
Add loglevel option to badips.py
2018-10-02 13:12:03 +02:00
Sergey G. Brester 65676baf8c fixed py3 incompatibility (for some reasons this file seems to be excluded from 2to3), anyway not needed, because int-type is already checked in str2LogLevel 2018-10-02 13:00:20 +02:00
Sergey G. Brester 4b751c84c3
badips.py: Rewrite new bool option "log" as "loglevel" and revert default to log-level (DEBUG). 2018-10-02 12:32:15 +02:00
sebres 58b510a5be 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);

sebres e2a255d104 fixed typo in comments by "ignoreself" parameter 2018-08-14 11:11:19 +02:00
sebres e995d5a0b6 filter.d/freeswitch.conf: provide 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`. 2018-08-03 11:42:15 +02:00
sebres bc2dbacc9a 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);

benrubson 30dc22fb2e Detect Apache SNI error / misredirect attempts 2018-03-29 11:36:49 +02:00
sebres 4f6532f810 filter.d/sshd.conf: mode `ddos` (and `aggressive`) extended to catch `Connection closed by ... [preauth]`, so in DDOS mode it causes failure now on closed within preauth stage;
at least using both modes can ban port-scanners and prevent for other annoying "intruders", closing connection within preauth-stage (see gh-2085 for example).

sebres cd7f1354c6 remove end-anchors for expressions that are precise enough (with clear flow, simple branches, without catch-all's, etc.) 2018-03-20 18:47:42 +01:00
sebres c31eb1c562 quick optimization: normalizes pam-generic prefregex (more similar to the same regex within sshd-filter) + datepattern anchored now; 2018-03-20 16:00:21 +01:00
sebres 25cc42129a hold all user names affected by interim attempts in order to avoid forget a failures after success login:
intruder (as legitimate user) firstly tries to login with another user-name (brute-force), so hopes to reset failure counter by succeeded login;
this is fixed and covered in tests now;
sshd-filter extended to cover multiple-login attempts (also fully implements gh-2070);
