sebres a2431158f6 implements new interpolation variable `%(fail2ban_confpath)s` (automatically substituted from config-reader path, default `/etc/fail2ban` or `/usr/local/etc/fail2ban` depending on distribution); `ignorecommands_dir` is unneeded anymore, thus removed from `paths-common.conf`;
fixes gh-3005

László Károlyi f380d6202d cherry pick #3210 from master 2022-02-09 15:43:21 +01:00
sebres 498e473a10 filter.d/courier-auth.conf: consider optional port after IP, regex is rewritten without catch-all's and right anchor, so it is more stable against further modifications now;
closes #3211

László Károlyi 0f1706d4a1
Adjusting for updated dovecot log format
This should now match:

`Disconnected: Connection closed: read(size=1003) failed: Connection reset by peer (auth failed, 1 attempts in 0 secs): user=<sales@karolyi.hu>, rip=183.111.188.94, lip=127.0.0.19, session=<Lsz0Oo7WXti3b7xe>`

the issue is the `read(size=1003)` that probably has been added lately and which causes the rule not to discover the log message.

sebres 06d2623c5e iptables and iptables-ipset actions extended to support multiple protocols with single action for multiport or oneport type (back-ported from nftables action);
