我正在使用以下命令连接到机器：
SSH myname@subname@150.25.10.10@20.35.10.10
试图弄清楚如何与 Paramiko 使用这种类型的连接。我试过像这样的命令：
vm.connect('20.35.10.10', username='myname@subname@150.25.10.10', password='passwrd%%%')
这给了我一个错误“身份验证失败”
或者，我尝试调整上一个 stackoverflow 问题的答案：Nested SSH using Python Paramiko 但是，这会引发“身份验证失败”错误。要连接的密钥文件保存在我的 ~/.ssh 文件夹中，我可以通过 shell 中的 ssh 命令进行连接，所以我认为我的密钥没有任何问题。对于连接到需要 user@user@ip@ip 格式的机器，似乎没有任何明确的说明
编辑：cyberark 连接的类型是 psmp
编辑：根据 Martin 的要求，这是 ssh -vvv name@subname@ip@ip 的输出，您可以猜到此输出已被清除，不会暴露敏感数据：
C:\>ssh -vvv myname@subname@150.25.10.10@20.35.10.10
