### Hinweise
|
||||
|
||||
- Der **Hostname** der IP wird automatisch per Reverse-DNS aufgelöst (`dig`, `host` oder `getent`). Ist kein PTR-Record vorhanden, wird `(unbekannt)` angezeigt.
|
||||
- Der **Servername** (`dns1` in den Beispielen) wird dynamisch über `$(hostname)` ermittelt und zeigt, auf welchem Server das Ereignis stattfand.
|
||||
- Die **Überschrift** unterscheidet sich je nach Aktion:
|
||||
- 🚨 🛡️ bei Sperren und Service-Stopp
|
||||
- ✅ bei Freigaben und Service-Start
|
||||
- Bei **permanenten Sperren** mit aktiviertem AbuseIPDB-Reporting wird ein Hinweis eingeblendet, dass die IP an AbuseIPDB gemeldet wurde.
