어떤 이유에서인지 내 미니컴퓨터에 IP 주소가 없어서 sudo ifdown eth2다음 명령을 실행했습니다 sudo ifup eth2. 이어진 것은 5분간의 원한 대결이었습니다. 내 고객은 누가 더 완고한지 알아보기 위해 서버와 싸웠습니다. 마침내 IP 주소를 얻었지만 요청했던 IP 주소는 얻지 못했습니다. 이 싸움의 원인은 무엇이며 이를 방지하려면 어떻게 재구성해야 합니까?

답변1
매번 이런 일이 일어나는 걸까요?
DHCP 서버가 인터페이스 eth0에 주소 172.20.44.71을 제공하려고 시도했지만 거부된 것 같습니다. 그런 다음 서버가 주소 172.20.44.15를 제공하면 해당 주소를 수락하는 DHCPACK이 있습니다.
구성 파일에는 다음 줄이 있습니다.
DHCP 요청 주소 172.20.44.15 보내기;
이 IP 주소가 정말로 필요합니까/사용하고 싶습니까? 이 줄을 제거하고 몇 가지 테스트를 실행해 보셨나요?
