Question

我试图在connect（）上获得Python paramiko超时。它适用于许多主机，但特别是一个主机，它永远不会超时。这是我的代码：

# python3
Python 3.4.2 (default, Oct  8 2014, 10:45:20)
...
>>> import paramiko
>>> ssh = paramiko.SSHClient()
>>> ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> ssh.connect(hostname="10.68.45.210", username="root", password="a_none_working_pass", timeout=2)

^CTraceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/paramiko/client.py", line 307, in connect
    look_for_keys, gss_auth, gss_kex, gss_deleg_creds, gss_host)
  File "/usr/lib/python3/dist-packages/paramiko/client.py", line 510, in _auth
    self._transport.auth_password(username, password)
  File "/usr/lib/python3/dist-packages/paramiko/transport.py", line 1166, in auth_password
    return self.auth_handler.wait_for_response(my_event)
  File "/usr/lib/python3/dist-packages/paramiko/auth_handler.py", line 192, in wait_for_response
    event.wait(0.1)
  File "/usr/lib/python3.4/threading.py", line 553, in wait
    signaled = self._cond.wait(timeout)
  File "/usr/lib/python3.4/threading.py", line 294, in wait
    gotit = waiter.acquire(True, timeout)
KeyboardInterrupt

我做错了什么？

我已经完成了一个过程，当它挂起时，我会循环获取这些消息：

select(0, NULL, NULL, NULL, {0, 1000})  = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 2000})  = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 4000})  = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 8000})  = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 16000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 32000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 36139}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 1000})  = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 2000})  = 0 (Timeout)

使用Python 2.7.3和3.4.2尝试使用Debian Jessie，两者都在无限循环中挂起。

编辑：似乎与此SO主题相关：Why does Paramiko hang if you use it while loading a module?但有没有办法搁置此问题？

我与Paramiko connect有同样的超时问题，对我有用的解决方案是将Paramiko更新为支持auth_timeout的最新版本。

session.connect('ipAddress', username='username', pkey=key, timeout=5, banner_timeout=5, auth_timeout=5)

Python paramiko connect没有超时
