Add journald support

[marcele]

Most new operating systems are switching to journald instead of syslog for logging as it provides a much needed unified interface for logging. It would be good if CSF could support this similar to fail2ban.

You should note that you wouldn't even have to change any regex as you can use the "short" output to match syslog:

Example:

View postfix logs:

Code: Select all

journalctl --no-pager --quiet --unit='postfix' --since='2022-10-30 00:00:00' --until='2022-11-06 23:59:59' --output='short'

If you only want to view posfix smtp logs:

Code: Select all

journalctl --no-pager --quiet --identifier='postfix/smtp' --since='2022-10-30 00:00:00' --until='2022-11-06 23:59:59' --output='short'
