paramiko为失败的连接抛出了什么错误/异常？

Question

如果失败:

ssh = paramiko.SSHClient()
ssh.connect( host, username = USER , pkey = MY_KEY, timeout = 2)

我得到一个追溯像:

  File "<stdin>", line 1, in <module>
  File "<stdin>", line 7, in bs_process
  File "/usr/lib/python2.7/site-packages/paramiko/client.py", line 282, in connect
    for (family, socktype, proto, canonname, sockaddr) in socket.getaddrinfo(hostname, port, socket.AF_UNSPEC, socket.SOCK_STREAM):
socket.gaierror: [Errno -2] Name or service not known

我无法确定Paramiko为错误的连接尝试抛出了什么类型的错误.哪些是异常类,如何导入它们？

Answer 1

您可以从查看API文档开始,以所有以Exception结尾的类:

http://docs.paramiko.org/en/1.15/api/client.html#paramiko.client.SSHClient.connect

然后,你也应该抓住socket.error.我想这会让你几乎所有的东西.例如,socket.gaierror是一个子类socket.error.

Answer 2

接受的答案有一个损坏的链接。Paramiko 的文档现在位于：

\n\n

http://docs.paramiko.org/en/1.15/api/client.html#paramiko.client.SSHClient.connect

\n\n

如果“connect”方法会引发以下问题：

\n\n

BadHostKeyException \xe2\x80\x93 if the server\xe2\x80\x99s host key could not be verified\nAuthenticationException \xe2\x80\x93 if authentication failed\nSSHException \xe2\x80\x93 if there was any other error connecting or establishing an SSH session\nsocket.error \xe2\x80\x93 if a socket error occurred while connecting\n
