Python pysft / paramiko'谈判期间的EOF'错误

标签: python python-2.7 paramiko pysftp

我使用pysftp下载并上传了一些文件。这个完全相同的代码我只是在一小时前运行并且很好,但是现在我在谈判期间得到了这个' EOF错误。我在这里缺少什么?

>>> sftp = pysftp.Connection(host, username=user, password=pasw)
>>> sftp
<pysftp.Connection object at 0x7f88b25bb410>
>>> sftp.cd('data')
<contextlib.GeneratorContextManager object at 0x7f88b1a86910>
>>> sftp.exists(filename)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pysftp/__init__.py", line 827, in exists
    self._sftp_connect()
  File "/usr/local/lib/python2.7/dist-packages/pysftp/__init__.py", line 205, in _sftp_connect
    self._sftp = paramiko.SFTPClient.from_transport(self._transport)
  File "/usr/local/lib/python2.7/dist-packages/paramiko/sftp_client.py", line 132, in from_transport
    return cls(chan)
  File "/usr/local/lib/python2.7/dist-packages/paramiko/sftp_client.py", line 101, in __init__
    raise SSHException('EOF during negotiation')
paramiko.ssh_exception.SSHException: EOF during negotiation

修改 为paramiko.transport启用了登录并获得以下内容:

仍然不知道出了什么问题......

3 个答案:

答案 0 :(得分:1)

我在使用密码验证的程序中遇到了同样的错误。弄清楚这是因为SFTP服务器上的密码已过期。重置它,一切正常。

答案 1 :(得分:0)

对于它的价值,在我的特定情况下,这是因为有人在OpenSSH中注释掉了SFTP子系统。在此处详细了解如何启用它:https://serverfault.com/q/660160/453708

答案 2 :(得分:0)

这是我固定的方式:“ / etc / ssh / sshd_config” 我正在使用centos,然后我看到这行代码(#),对我来说,这是sftp的错误二进制文件,然后我发现了好代码,似乎对我有用:

Subsystem sftp /usr/libexec/openssh/sftp-server
#Subsystem sftp /usr/lib/openssh/sftp-server

对于lsb或debian,请尝试以下操作:

Subsystem sftp internal-sftp

谢谢。
