nscd (Nameservices Cache Daemon)를 사용하여 DNS를 로컬로 캐시하려고하므로 Bind 사용을 중지 할 수 있습니다. 나는 그것을 시작했고 ntpd는 그것을 사용하려고하는 것 같습니다. 그러나 호스트를위한 다른 모든 것들은 무시하는 것 같습니다. 예를 들어, 내가 apache.org를 3 번 발굴하면 캐시에 닿지 않을 것입니다. 캐시 통계 사용 nscd -g
여부를 확인하는 데 사용하고 있습니다. 또한 디버그 로그 수준을 높이고 그것이 치는 것을 볼 수 있고 쿼리가 nscd에 도달하지 않는지 확인했습니다.

나는 일종의 부수적으로 아치 리눅스를 사용하고 있습니다.
참고 : 이것은 두 번 옮겨졌으며, 발굴을 제외한 앱이 왜 nscd 캐시, 브라우저, IM, IRC에 충돌하지 않았는지 알지 못했습니다.
