Sharing network configuration files (e.g. to get help debugging) can be quite tricky because they contain sensitive information. At the same time, simply removing the sensitive information (e.g. removing or changing all IP addresses) removes important structure from the files, defeating the purpose of sharing. We created Netconan to help. Netconan is an open source Python tool that anonymizes sensitive network information from text files, while preserving important structure. For example: it can take in router configuration files and remove passwords and anonymize IP addresses, while preserving IP address relationships (prefixes/subnets that matched before anonymization will still match after anonymization). Check it out on PyPI (https://pypi.python.org/pypi/netconan/) or GitHub ( https://github.com/intentionet/netconan) and let us know what you think! Thanks, Spencer
