Python utility scripts for working with a Juniper NetScreen ScreenOS configuration file offline.

  • screenos_validation - generates reports for network duplications, address group and book entry duplication, unused address group and book entries, unused service entries, and address book entries for hostnames that do not resolve
  • policy_view - print policies offline from a configuration file similar to the cli


  • Python >= 2.6

Caveats for Validation script

  • No support for IPv6 entries.
  • Does not validate policies for correctness.
  • Does not check for duplicate service entries.
  • Duplicate network report requires a large screen resolution to view properly.
  • Currently reports on address book entries that lie along the same network boundary and are not necessarily identical. e.g. ~

Caveats for Policy script

  • Does not report on Attack, Schedule, or Traffic shaping options in policies and will always display ---.
  • ANSI colors are specific to the BASH shell. Have not tested with others.
  • Requires Python >= 2.7 to support the OrderedDict collection or installation of ordereddict (easy_install ordereddict)
