无法使用 Paramiko 包连接到服务器

Question

我在 Python 中尝试使用端口 2022（不是 22）的 SSH 连接到我的服务器。所以我编写了以下使用 Paramiko 包的代码：

import sys
import paramiko

try:
  client = paramiko.SSHClient()
  client.load_system_host_keys()
  client.set_missing_host_key_policy(paramiko.WarningPolicy)
  client.connect('ccap@10.40.2.222', '2022', '', 'ccap')
finally:
  client.close()

但是当我运行它在我的 IDE (PyCharm) 中时，我收到以下错误：

/usr/local/lib/python3.5/dist-packages/paramiko/ecdsakey.py:164: CryptographyDeprecationWarning: Support for unsafe construction of public numbers from encoded data will be removed in a future version. Please use EllipticCurvePublicKey.from_encoded_point self.ecdsa_curve.curve_class(), pointinfo

Traceback (most recent call last):

Answer 1

您应该将用户名作为单独的参数提供，而不是添加到主机地址之前。

Look at the docs for .connect。它有 username 和 hostname 分别列出。
