SSH를 통해 VirtualBox 가상 머신에 연결할 수 없습니다

호스트 전용 어댑터를 사용하여 Ubuntu VirtualBox VM을 설정했습니다. Ubuntu 사용자는 다음을 remy통해 연결을 확인했습니다 ping.

가상 머신에서 이 작업을 수행합니다(이번에는 NAT 네트워크 연결을 사용하여 인터넷에 연결).

sudo apt install openssh-client openssh-server

sshd실행중인지 확인해보니

ps -A | grep ssh

산출:

<pid> ? 00:00:00 sshd

다음 명령을 사용하여 Mac OS 호스트에서 게스트 서버에 연결하려고 합니다.ssh -v [email protected]

산출:

SSH를 처음 사용합니다. 도움을 주시면 감사하겠습니다.
