    Das Logging von IPTables in ein File namens iptables.log schreiben.

    Datei /etc/rsyslog.conf file bearbeiten

    nano /etc/syslog.conf

    Diese Zeile ans Ende einfügen

    kern.warning /var/log/iptables.log

    Den Dienst rsyslog service neustarten

    service rsyslog restart

    Fertig 😉

    Sieht dann so aus. Im File /var/log/iptables.log

    Jan 26 13:09:27 rock64 kernel: [13190.584780] [FW FORWARD ]: IN=eth1.200 OUT=eth1.100 MAC=00:e0:4c:68:02:6f:3c:97:0e:8b:30:31:08:00 SRC=192.$

    Heute mal drüber gestolpert, das es auch so was geben kann. root@pve2:~# zpool status pool: pool_NAS state: ONLINE status: Some supported and requested features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired 0B in 00:20:50 with 0 errors on Sun Apr 13 00:44:51 2025 config: NAME STATE READ WRITE CKSUM pool_NAS ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ata-WDC_WDS100T1R0A-68A4W0_230520800733 ONLINE 0 0 0 ata-WDC_WDS100T1R0A-68A4W0_230520801376 ONLINE 0 0 0 errors: No known data errors Was machen?
