CENTOS 7 1816 버전의 console 모드에서 network 설정에 관한 내용입니다. ※ 저는 virtualbox에 CENTOS를 설치 해두었기 때문에 해당 기준으로 내용 작성하였습니다. NAT 과 BRIDGE 설정만 알면 대부분의 원하는 네트워크 작업이 가능합니다. 두 방식의 차이점은 다음과 같습니다. 1. NAT(network address translation)은 virtual box에 할당된 network adapter의 IP를 base로 VM에 가상 IP를 부여합니다. 공유기에서 내부 IP를 여러 기기에 부여하는 방식입니다. - 외부에서 VM으로 접근하기 위해서 port forwarding이 필요합니다.

virtual box 를 사용중 어느 순간 다음과 같이 "가상 머신의 세션을 열 수 없습니다" 라는 메세지의 오류 창이 뜨며 vm이 실행되지 않았다. 해결을 위해 vm도 다시 만들어보고, vm만들때 옵션도 달리 해보고, 구글링에 나와있는 virtual box expension pack 도 설치해 보았지만 아무 소용 없었다.
