로컬 재귀 DNS 서버로 언 바운드를 사용하고 있습니다. 로컬 LAN DNS를 설정하기 위해 nsd를 추가했습니다. nsd는 포트 53530에서 수신 대기 중이며 정상적으로 작동합니다.

특히 무엇입니까? [1947 : 0] 디버그 : donotquery 목록 ip4 127.0.0.1 포트 53530에서 addr를 건너 뛰십시오.

내 전체 unbound.conf는 다음과 같습니다.

server:
  interface: 127.0.0.1
  interface: 192.168.1.50
  use-syslog: yes
  username: "unbound"
  directory: "/etc/unbound"
  trust-anchor-file: trusted-key.key
  access-control: 192.168.1.0/24 allow
  verbosity: 2
  local-zone: "1.168.192.in-addr.arpa" nodefault
remote-control:
  control-enable: yes
  control-interface: 127.0.0.1
  control-port: 8953
  server-key-file: "/etc/unbound/unbound_server.key"
  server-cert-file: "/etc/unbound/unbound_server.pem"
  control-key-file: "/etc/unbound/unbound_control.key"
  control-cert-file: "/etc/unbound/unbound_control.pem"

stub-zone:
  name: "datanet.home"
  stub-addr: 127.0.0.1@53530
#  stub-first: yes
stub-zone:
  name: "1.168.192.in-addr.arpa"
  stub-addr: 127.0.0.1@53530

nsd.conf에는 많은 주석이 있으므로 붙여 넣을지 확실하지 않지만 nsd는 제대로 작동하는 것 같습니다. 포트 변경, 제어 기능 활성화 및 영역 추가를 제외하고는 포함 된 예제 conf와 거의 동일합니다.

나는 이것으로 혼란에 빠졌으므로 어떤 아이디어라도 높이 평가 될 것입니다!
