Python Paramiko挂起ssh.opensftp（）

我尝试运行以下脚本：

import paramiko
import os

host, port, user, passw, key = .... 

transport = paramiko.Transport((host, port))
ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

private_key_file = key
paramiko.util.log_to_file("filename.log")
xSx_key = paramiko.RSAKey.from_private_key_file(private_key_file,None)
transport.connect(username = user, password=passw, pkey = xSx_key)
ssh.connect(host, username=user, password=passw, pkey=xSx_key, port=port) 


ftp = ssh.open_sftp()
files = ftp.listdir()

不幸的是，这在open_sftp（）调用期间挂起。如果随后执行键盘中断，则会得到以下堆栈跟踪：

  ftp = ssh.open_sftp()
  File "build\bdist.win-amd64\egg\paramiko\client.py", line 379, in open_sftp

我想知道“未处理的类型3”是否有任何提示？我试图连接到的服务器需要user、pass和keyfile

任何建议都将不胜感激，因为我在这里不知所措。请注意，我可以使用WinSCP等连接到此服务器而不会出现问题

谢谢
