Build workflog Documentation Status

Performs static analysis on network device configuration files.

Linters have long since been a standard way of assessing code quality in the software development world. This project aims to take that idea and apply it to the world of network device configuration files.

Find the latest copy of the documentation here.

Potential uses of this tool are

  • Linting network device configurations generated in CI/CD automation pipelines

  • Assistance when building out new configurations for both traditional and automated deployment

  • Basic security auditing of configuration files

Example usage

Below is an example of how to use this based on one of the faulty test configurations (executed from the project root):

$  netlint --nos cisco_ios tests/cisco_ios/configurations/faulty.conf
IOS101 Plaintext user passwords in configuration.
-> username test password ing
IOS102 HTTP server not disabled
-> ip http server
-> ip http secure-server
IOS103 Console line unauthenticated
-> line con 0


There are multiple ways of installing this software.

A package is available on PyPI, therefore you can simply install with pip install netlint and then simply run netlint.

If you prefer to install directly from GitHub, here is how you would go about that.

$ git clone
$ cd netlint
$ pip install .
$ netlint --help
Usage: netlint [OPTIONS] COMMAND [ARGS]...
