我正在尝试从 VMware ESXi 8 计算机连接到 VMware ESXi 5 计算机以传输所有虚拟机。问题是 ssh 无法连接。旧机器有 OpenSSH 5，新机器有 OpenSSH 9。
当我从计算机连接到旧机器时，我使用：
ssh -oHostKeyAlgorithms=+ssh-dss -o ServerAliveInterval=30 user@machine
允许与该过时的算法连接。但是，如果我在 ESXi 8 上尝试这样做，它不起作用，并显示“非法参数”：
[root@s02:~] ssh -vvv -oHostkeyAlgorithms=+ssh-dss user@machine

也尝试过
ssh -vvv -oHostkeyAlgorithms=+ssh-rsa user@machine
但问题是一样的，总是非法的争论。
