모든 가상 머신을 전송하기 위해 VMware ESXi 8 머신에서 VMware ESXi 5 머신으로 연결하려고 합니다. 문제는 ssh 접속이 안된다는 점입니다. 이전 머신에는 OpenSSH 5가 있고 새 머신에는 OpenSSH 9가 있습니다.
내 컴퓨터에서 이전 컴퓨터에 연결할 때 다음을 사용합니다.
ssh -oHostKeyAlgorithms=+ssh-dss -o ServerAliveInterval=30 user@machine
이 오래된 알고리즘과의 연결을 허용합니다. 그러나 ESXi 8에서 이것을 시도하면 작동하지 않고 "잘못된 매개변수"라는 메시지가 나타납니다.

ssh -vvv -oHostkeyAlgorithms=+ssh-rsa user@machine
하지만 문제는 똑같습니다. 항상 불법적인 논쟁입니다.
