ncclient is a Python library that facilitates client-side scripting and
application development around the NETCONF protocol. ncclient was
developed by Shikar Bhushan. It is now
maintained by Leonidas Poulopoulos (@leopoul)
Docs: http://ncclient.readthedocs.org
- Python 2.6 <= version < 3.0
- setuptools 0.6+
- Paramiko 1.7+
- lxml 3.0+
- libxml2
- libxslt
If you are on Debian/Ubuntu install the following libs (via aptitude or apt-get):
- libxml2-dev
- libxslt1-dev
[ncclient] $ sudo python setup.py install
or via pip:
pip install ncclient
[ncclient] $ python examples/juniper/*.py
Use either an interactive Python console (ipython) or integrate the following in your code:
from ncclient import manager
with manager.connect(host=host, port=830, username=user, hostkey_verify=False) as m:
c = m.get_config(source='running').data_xml
with open("%s.xml" % host, 'w') as f:
f.write(c)
As of 0.4.1 ncclient integrates Juniper's and Cisco's forks, lots of new concepts have been introduced that ease management of Juniper and Cisco devices respectively. The biggest change is the introduction of device handlers in connection paramms. For example to invoke Juniper's functions annd params one has to re-write the above with device_params={'name':'junos'}:
from ncclient import manager
with manager.connect(host=host, port=830, username=user, hostkey_verify=False, device_params={'name':'junos'}) as m:
c = m.get_config(source='running').data_xml
with open("%s.xml" % host, 'w') as f:
f.write(c)
Device handlers are easy to implement and prove to be futureproof.
- Juniper: device_params={'name':'junos'}
- Cisco CSR: device_params={'name':'csr'}
- Cisco Nexus: device_params={'name':'nexus'}
- Huawei: device_params={'name':'huawei'}
