The first feature release of the 5.7 series of NAV is now out!

The source code is available for download at GitHub.

New packages for Debian 10 (Buster) and 11 (Bullseye) are available in our APT repository as usual. We haven’t started building packages for Debian 12 (Bookworm) yet, but hope to do so by the end of 2023.

Please be extra aware of config file changes. Look out for *.dpkg-dist files in /etc/nav and make sure to update your running config.


  • Even more complex and flexible configuration of NAV logging is now supported through logging.yml (#2659)

  • Added support for polling and alerting on Juniper chassis and system alerts (#2358, #2388)
    • Juniper only provides alert counters via SNMP, no alert details, unfortunately.

    • These are needed for the upcoming vendor specific implementations of PoE config in PortAdmin.
