如何使用Python的Paramiko模块ssh到需要两个密码身份验证的服务器？

服务器对第一个密码使用标准密码身份验证

第二个密码仅在shell启动时询问。简单的I/O用于此

此外，您的服务器似乎不支持“exec”接口/通道来执行命令（因为ssh user@host command不起作用）。可能与“shell密码”功能相关的内容。因此，您可能必须使用“shell”通道来执行命令，否则不推荐使用

ssh = paramiko.SSHClient()
ssh.connect(hostname, username = username, password = password1)
channel = ssh.invoke_shell()
channel.send(password2 + "\n")
channel.send(command + "\n")
while not channel.recv_ready():
    time.sleep(1)
out = channel.recv(9999)
