python - 使用 pxssh 进行 SSH 时 python 代码出错

Question

我正在尝试通过 python 连接 SSH。我尝试使用不同的方法来消除错误，但仍在努力消除错误。这是我的代码:

1) import pxssh
   import getpass
   def get_ssh():
    s= pxssh.pxssh()
    hostname = raw_input('IP: ')
    username = raw_input('username: ')
    password = getpass.getpass('password: ')
    s.login (IP, username, password)
    s.logout()
    return True

2)   s= pxssh.pxssh(timeout='time_out', maxread=20000)
     s.SSH_OPTS += " -o StrictHostKeyChecking=no"
     s.SSH_OPTS += " -o UserKnownHostsFile=/dev/null"
     s.login ('IP', 'username', 'password')

在这两种方式中，我都遇到了同样的错误。我还需要一些有关如何传递私钥和公钥进行身份验证的信息:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "mit_test.py", line 11, in get_ssh
    s.login (hostname, username, password)
  File "/usr/lib/python2.7/dist-packages/pxssh.py", line 196, in login
    i = self.expect(["(?i)are you sure you want to continue connecting", original_prompt,
    "(?i)(?:password)|(?:passphrase for key)", "(?i)permission denied", "(?i)terminal type", 
    TIMEOUT, "(?i)connection closed by remote host"], timeout=login_timeout)
  File "/usr/lib/python2.7/dist-packages/pexpect.py", line 1316, in expect
    return self.expect_list(compiled_pattern_list, timeout, searchwindowsize)
  File "/usr/lib/python2.7/dist-packages/pexpect.py", line 1330, in expect_list
    return self.expect_loop(searcher_re(pattern_list), timeout, searchwindowsize)
  File "/usr/lib/python2.7/dist-packages/pexpect.py", line 1401, in expect_loop
    raise EOF (str(e) + '\n' + str(self))
pexpect.EOF: End Of File (EOF) in read_nonblocking(). Exception style platform.

searcher: searcher_re:
    0: re.compile("(?i)are you sure you want to continue connecting")
    1: re.compile("[#$]")
    2: re.compile("(?i)(?:password)|(?:passphrase for key)")
    3: re.compile("(?i)permission denied")
    4: re.compile("(?i)terminal type")
    5: TIMEOUT
    6: re.compile("(?i)connection closed by remote host")

我到底需要做什么？我搜索了一些其他评论，但找不到任何解决方案。另外，如何在登录参数中设置私钥路径？谁能帮我？我浏览了不同的帖子 link [链接] ( EOF when using pexpect and pxssh ) 但找不到解决方案。谢谢你的时间。

您的程序尝试连接的主机是新的主机。首先必须接受主机的 key ，然后才能进行身份验证。在终端上，这需要键入"is"。您可以使用 SSH 选项关闭主机 key 检查。

s = pxssh.pxssh(options={
    "StrictHostKeyChecking": "no"})
