Sergey G. Brester	c88967df2d	filter.d/exim.conf - introduces mode more (several rules moved from mode normal to more), because: ... - they have basically nothing with authentication; - they can cause false positives (e. g. someone sends several mails from google mailing server to wrong recipients and if they would cause "rejected RCPT - Unknown user", the google host gets banned; - to avoid occasional ban of legitimate servers one'd need create large white-list for `ignoreip` or construct complex `ignorecommands` to exclude all legitimate servers of big players (like google, microsoft, GMX, etc);	2025-02-13 21:30:04 +01:00

MichaIng	eb8b44370a	Make Dropbear regex more compatible and simpler ... Dropbear uses `strftime` `"%b %d %H:%M:%S` to print its timestamps, hence we know the day and time format, but the month could be localized. We hence allow any 3 word characters for it, and additionally simplify the day and time pattern into a single group. Signed-off-by: MichaIng <micha@dietpi.com>	2024-12-27 14:00:36 +07:00
MichaIng	dd9f359f5c	Fix Dropbear filter when logging to STDOUT ... Since Debian Bookworm, the distribution ships Dropbear with a native systemd service instead of the default upstream init.d service, and accordingly uses the `-F` and `-E` flags, to run it in foreground and have it logging to STDOUT instead of syslog. As usual, timestamps and also the PID are now included by the log message emitted by Dropbear, in addition to the systemd journal log prefix. The Dropbear filter hence does not match anymore. This commit adds the PID and timestamp as optional pattern between prefix and fail log text, to support Dropbear on Debian Bookworm and newer (and likely new versions of other distros) without breaking the old pattern when running Dropbear without `-E` flag. Additionally, for performance reasons, this commit adds a `journalmatch` entry, matching Debian's and Fedora's `dropbear.service` with `dropbear` executable/identifier, the most likely match for a Dropbear systemd service.

Vladimir Varlamov	df94ec4c52	filter.d/exim.conf: rewrite host line regex for all varied exim's log_selector states ... Depending on Exim's log_selector settings, log lines may contain additional information about the connection. And also the line itself with the address of the remote host can vary greatly. But fortunately, all states can be found in the Exim code itself and taken into account. Makes it easier to add new regexps. Closes #3263	2024-03-22 00:16:41 +03:00
