使用python連接SSH時出現錯誤

Question

我正在嘗試使用python連接在Windows中運行的Virtual CentOS計算機之一。

我已經安裝了paramiko模塊來做。 但低於錯誤

C:\Users\xxxx\PycharmProjects\xxxx\venv\lib\site-packages\paramiko\kex_ecdh_nist.py:39: CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a future version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
  m.add_string(self.Q_C.public_numbers().encode_point())
C:\Users\xxx\PycharmProjects\xxxx\venv\lib\site-packages\paramiko\kex_ecdh_nist.py:96: 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.curve, Q_S_bytes
C:\Users\xxxx\PycharmProjects\xxxx\venv\lib\site-packages\paramiko\kex_ecdh_nist.py:111: CryptographyDeprecationWarning: encode_point has been deprecated on EllipticCurvePublicNumbers and will be removed in a future version. Please use EllipticCurvePublicKey.public_bytes to obtain both compressed and uncompressed point encoding.
  hm.add_string(self.Q_C.public_numbers().encode_point())

下面是我的代碼：

import paramiko

ssh = paramiko.client.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
    ssh.connect('10.xx.xx.xxx', username='root', password='xxxxx')
except paramiko.SSHException:
    print("Connection Failed")
    quit()

stdin, stdout, stderr = ssh.exec_command("ls /etc/")

for line in stdout.readlines():
    print
    line.strip()
ssh.close()

我使用PyCharm 2018.3社區版搜索並安裝了密碼學2.6.1和python版本3.7.1 。

請讓我知道我在這里做錯了

Answer 1

這些不是錯誤，這些是paramiko發出的警告，它們需要更新代碼以使用更多最新參數。 您的代碼仍然應該運行。 最好的選擇是查看paramiko軟件包的作者是否有更新版本或提出問題。

Answer 2

不推薦使用Paramiko使用的方法。 您應該考慮將Python降級到較低版本或下載Paramiko的更新版本（如果存在）
