Ubuntu 18.04 VM을 Virtual Box Nat 네트워크에 연결

VirtualBox Nat Networking을 사용하여 가상 머신 네트워크를 설정하려고 합니다. 일부 VM, 특히 Coreos 박스와 Metasploitable 클러스터는 잘 연결되어 있습니다. 다른 것, 특히 내가 직접 설정한 Ubuntu 가상 머신은 그렇지 않습니다.

NAT 네트워크 설정은 다음과 같습니다

$ VBoxManage natnetwork list fabian
NAT Networks:

Name:        fabian
Network:     172.17.8.0/24
Gateway:     172.17.8.1
IPv6:        No
Enabled:     Yes

/etc/network/interfaces읽기 위해 Ubuntu vms 파일을 편집해 보았습니다.

# interface(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

# network interface
auto enp0s3
iface enp0s3 inet dhcp

/etc/network/interfaces(이 부분은 네트워크에 잘 연결된 것으로 보이는 우분투 기반 가상 머신인 Metasploitable의 파일을 기반으로 합니다 .)

그러나 실행하려고 하면 $ sudo systemctl restart networking정지되고 시간이 초과됩니다. 아래에 출력을 포함시켰습니다 $ journalctl -xe. 이전에 일부 항목을 포함했지만 메시지는 동일하지만 간격이 다른 것 같습니다.

네트워크 인터페이스 설정을 위해 연결할 때 뭔가 빠졌나요?

답변1

Ubuntu 17.10부터 이 ifupdown도구는 더 이상 사용되지 않는 도구로 간주되어 로 대체되었습니다 netplan. 이 패키지를 사용하려면 를 설치해야 합니다 /etc/network/interfaces.ifupdown

귀하의 경우에는 다음 도구를 사용하여 네트워크를 구성해야 합니다 netplan.

구성 파일은 아래에서 찾을 수 있습니다 /etc/netplan/. 다음과 같이 파일을 생성/편집합니다 *.yaml.

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      dhcp4: true

네트워크 관리자가 설치되어 있으면 다음 renderer: networkd으로 교체할 수 있습니다.renderer: NetworkManager

그런 다음 다음을 실행하십시오.

sudo netplan generate
sudo netplan apply

바라보다:

Netplan으로 마이그레이션
