python - 如何在 paramiko 连接中临时添加 host_key

Question

我正在使用 Paramiko 连接到 SSH 服务器，并且我想临时添加“host_keys”。

我该怎么做？

import paramiko

client = paramiko.SSHClient()
client.load_system_host_keys()
#client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=str(host),username =str(user),password=str(pswd))

Answer 1

from paramiko import RSAKey
from paramiko.py3compat import decodebytes

client = SSHClient()

# known host key
know_host_key = "<KEY>"
keyObj = RSAKey(data=decodebytes(know_host_key.encode()))

# add to host keys
client.get_host_keys().add(hostname=HOST, keytype="ssh-rsa", key=keyObj)

# login to ssh hostname
client.connect(hostname=HOST, port=PORT, username=USER)...
