Rekomendasi ini tidak dapat diperiksa secara otomatis. Pemindaian akan menampilkannya beserta petunjuk ini saat Anda memberikan opsi --include-manual.

Run systemctl list-unit-files --type=service --state=enabled and ss -tlnp on every TDSQL host. Only TDSQL components (mysqld, oss_server, scheduler, zookeeper, gateway/proxy, agents) and required OS services may be enabled or listening; services such as cups, avahi-daemon, bluetooth or telnet are a finding.

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

# Disable unnecessary services systemctl disable --now cups avahi-daemon bluetooth telnet.socket
