ncclient:连接到NETCONF服务器

Question

我想使用python库ncclient0.6.6和Python2.7.15连接到NETCONF服务器(netopeer2)并读取运行配置。

我尝试遵循手册中的示例，在控制台中运行以下代码：

with manager.connect(host="*the IP adress*", port=*the port*, timeout=None, username="*user*", password="*pwd*") as m:
    c = m.get_config(source='running').data_xml
    with open("%s.xml" % host, 'w') as f:
        f.write(c)

正如手册中所写的，我尝试在allow_agent和look_for_keys为False的情况下禁用公钥身份验证。不幸的是，这不能正常工作，因为我得到了错误消息：

  File "<stdin>", line 1, in <module>
  File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/manager.py", line 177, in connect
    return connect_ssh(*args, **kwds)
  File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/manager.py", line 143, in connect_ssh
    session.connect(*args, **kwds)
  File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/transport/ssh.py", line 481, in connect
    raise SSHUnknownHostError(known_hosts_lookup, fingerprint)
ncclient.transport.errors.SSHUnknownHostError: Unknown host key [e3:8d:35:a9:43:f9:3c:8a:f4:d3:88:5b:a9:36:93:59] for [[192.168.56.2]:1831]

我不明白为什么它仍然抱怨未知的主机密钥，即使我显式禁用了公钥身份验证。netopeer NETCONF服务器肯定在运行，因为只要我尝试从终端外通过SSH进入服务器，就会收到一条"Hello“消息。我错过了什么吗？

Answer 1

m = manager.connect(host="172.17.0.2", port=830, username="netconf", password="netconf", hostkey_verify=False)

成功了。Hostkey_verify必须为false。
