IP 주소가 할당되지 않은 모든 인터페이스에 대해 이 작업을 반복합니다.
제 생각에는 이것이 dhcp와 관련이 있는 것 같습니다. 어떤 인터페이스에서도 DHCP 클라이언트가 실행되는 것을 원하지 않습니다. 이러한 인터페이스 중 일부에는 고정 주소가 있고 다른 인터페이스에는 없습니다. 인터페이스에 대한 IP 주소가 없는 것 같습니다. NetworkManager는 기본적으로 자동 구성을 사용하고 DHCP를 얻으려고 시도합니다. 링크 로컬을 할당하면 APIPA 주소를 얻게 되지만 그것도 원하지 않습니다.
IP 주소 없이 하나의 인터페이스만 활성화할 수 있습니까? NetworkManager가 IP를 얻으려는 시도를 중지하게 하시겠습니까?
