# ncclient: Python library for NETCONF clients
ncclient is a Python library that facilitates client-side scripting
and application development around the NETCONF protocol. `ncclient` was
developed by [Shikar Bhushan](http://schmizz.net). It is now maintained
by [Leonidas Poulopoulos (@leopoul)](http://ncclient.org) and Einar Nilsen-Nygaard (@einarnn)
**Docs**: [http://ncclient.readthedocs.org](http://ncclient.readthedocs.org)
**PyPI**: [https://pypi.python.org/pypi/ncclient](https://pypi.python.org/pypi/ncclient)

| 07/02/18 | `0.6.0` | Minor release reinstating Python 3.7 and greater compatibility, but necessitating a change to client code that uses `async_mode`. |
| 07/02/18 | `0.5.4` | New release rolling up myriad of small commits since `0.5.3`. Please note that this release is **incompatible wth Python 3.7** due to the use of a new Python 3.7 keyword, `async`, in function signatures. This will be resolved in 0.6.0|
## Requirements
* Python 2.7 or Python 3.5+
* setuptools 0.6+
* Paramiko 1.7+
* lxml 3.3.0+
* libxml2
* libxslt
If you are on Debian/Ubuntu install the following libs (via aptitude or apt-get):
* libxml2-dev
* libxslt1-dev
## Installation
[ncclient] $ sudo python setup.py install
or via pip:
pip install ncclient
Also locally via pip from within local clone:
pip install -U .
## Examples
[ncclient] $ python examples/juniper/*.py
## Usage
### Get device running config
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.
### Supported device handlers
When instantiating a connection to a known type of NETCONF server:
* Alcatel Lucent: `device_params={'name':'alu'}`
* Ciena: `device_params={'name':'ciena'}`
* Cisco:
- CSR: `device_params={'name':'csr'}`
- Nexus: `device_params={'name':'nexus'}`
- IOS XR: `device_params={'name':'iosxr'}`
- IOS XE: `device_params={'name':'iosxe'}`
* H3C: `device_params={'name':'h3c'}`
* HP Comware: `device_params={'name':'hpcomware'}`
* Huawei:
- `device_params={'name':'huawei'}`
- `device_params={'name':'huaweiyang'}`
* Juniper: `device_params={'name':'junos'}`
* Server or anything not in above: `device_params={'name':'default'}`
## For Developers
### Running Unit Tests Locally
To run the same tests locally as are run via GitHub's CI/CD integration with Travis, the following istructions can be followed:
1. Create a virtual environment, in this case using `virtualenvwrapper`:
```
mkvirtualenv ncclient-testing
```
1. Install your local `ncclient` package (ensuring you are in your virtual environment):
```
pip install -U .
```
1. Install testing dependencies:
```
pip install pytest coverage coveralls mock
```
1. Finally, run the tests:
```
pytest test --verbosity=3
```
For coverage, showing missing lines do:
```
coverage run -m pytest test --verbosity=3 && coverage report -m
```
### Making a Release
As of `0.6.1`, `versioneer` has been integrated into the `ncclient` codebase. This simplifies the creation of a new release, by ensuring that version numbers are automatically generated from the git tag used for the release, which **must** be in the form `v0.1.2`. Versioneer also allows for the clean install of development versions locally using pip. For example:
```
$ pip install -U .
Processing /opt/git-repos/versioneer-ncclient

```
Thus, making a release becomes a simple process:
1. Ensure all tests run clean (ideally both locally and via Travis) and that `README.md` (yes, this file!!) has been updated appropriately.
2. Apply appropriate version tag, e.g. `git tag v0.6.1`
3. After ensuring `build` is installed, build packages:
```
python -m build
```
4. After ensuring twine is installed, test twine upload:
```
twine upload \
--repository-url https://test.pypi.org/legacy/ \
-u ******* -p ******* \
dist/*
````
5. Push git tags back to origin, `git push --tags`
6. Do real twine upload:
```
twine upload \
-u ******* -p ******* \
dist/*
```
