NAV

It’s Friday the 13th and a pandemic is upon us, so we thought: Why not release the fifth maintenance version of the 5.0 series of NAV!

The source code is available for download at GitHub.

New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository as usual.

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

The virtual appliance will be updated shortly.

Deprecation warning

Python 2 reached its end-of-life on January 1, 2020. NAV 5.0 therefore moves to Python 3, and as such, you will need at least Python 3.5 to run NAV.

Most of NAV will still run on Python 2 as of the 5.0 release, but from this point, Python 2 will be deprecated and we will start removing code that exists solely to keep compatibility with Python 2.

Fixed GitHub issues in this release:

• #1994 (snmptrapd linkupdown plugin does not handle v2 traps)
• #2101 ([BUG] Geomap data API endpoint crashes with a TypeError)
• #2109 ([BUG] ipdevinfo sensor details page crashes with AttributeError on unit-less sensors)
• #2111 ([BUG] Logging non-ASCII characters crashes NAV programs)
• #2113 (Document advice for robust e-mail)
• #2114 ([BUG] Unable to save status filter in [Status] page)
• #2119 ([BUG] Latitude/Longitude is displayed weirdly in the SeedDB room list)
• #2123 (Drop support for legacy status preference pickles)
• #2129 (Euthanize unresponsive ipdevpoll workers)
• #2130 ([BUG] Cannot import dashboard)

The eighth maintenance release of the 4.9 series of NAV is now out!

The source code is available for download at GitHub.

New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository as usual.

The Debian packages for NAV 4.9 have been rebuilt using dh-virtualenv, which means that most of the Python dependencies are now embedded into the packages themselves. If you have previously added a priority apt pin for packages from apt.uninett.no, you may now remove it, as there are no longer any other packages needed from that repository to run NAV.

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

The virtual appliance has been updated.

Fixed GitHub issues in this release:

• #1753 (SNMP-less servers are no longer connected in the NAV topology)
• #1941 (Interface information pop-ups in the status widget tends to hang)
• #1942 (get_mib() should be able to load MIB modules from outside the nav.smidumps package)
• #1962 (Environment rack widget edit mode crashes if there are racks in rooms with non-ascii characters in their name)
• #1964 (smsd crashes when discarding non-dispatchable messages with non-ASCII chars (or for users with non-ASCII chars in their name))
• #1972 (Ensure PostgreSQL unique constraints are consistently named)
• #1973 (Stop explicitly installing pl/pgSQL during db init.)
• #1975 (Unhandled ValueError in eventengine when snmptrapd posts invalid linkState events)
• #1976 (Properly display sensor data scale on sensor details page.)
• #1977 (Use Juniper 802.1X VLAN workaround in default configuration)

Happy NAVing everyone!

Hi everyone,

this is a two-fold announcement:

1. We have, as of today, published a NAV 4.9.7 package for Debian 10 (Buster) in our regular APT repository. Please see the updated instructions for use of the APT repository.

2. As previously mentioned, we are now discontinuing support for the Debian 8 (Jessie) line of NAV packages. There will be no new updates for this outdated platform from our side.

There is, however, one caveat to using the NAV package on Debian 10: If you want to serve both the NAV web UI and Graphite-web from the same server, you cannot achieve this on Debian 10 using the regular Apache + mod_wsgi method for both applications.

Debian 10 ships with a graphite-web package that runs on Python 3, while NAV 4.9 does not support Python 3 (we expect the next feature release to run on Python 3). mod_wsgi cannot be made to serve both Python versions on the same Apache server - you will have to select a Python-version specific mod_wsgi package.

For this reason, the virtual appliance has not yet been updated to Debian 10.

For our production deployments, we serve up NAV and Graphite-web using a uWSGI application server, and use Apache + mod_uwsgi as a front to provide TLS and serving of static file resources. This works fine on Debian 10, as each uWSGI application instance is an independent process.

UPDATE: The NAV virtual appliance has now been updated to run on Debian 10, using uWSGI to run Graphite-web under Python 3, separately from NAV (which still runs in mod_wsgi, at the moment). The documentation has been updated.

For the past 10 years or so, NAV has supported Jabber (via the XMPP protocol) as one of its possible notification dispatch methods. XMPP support is implemented through the xmpppy library, which seems to be unmaintained, and is not compatible with Python 3. As we no longer have customers who rely on NAV notifications via XMPP, we will no longer put resources into supporting it, and will be removing it as part of NAV’s transition to Python 3.

If you are someone who actually depends on XMPP notifications from your NAV, I would urge you to consider contributing a replacement implementation.

The only Python-based XMPP implementation currently listed on https://xmpp.org/ seems to be this one: https://lab.louiz.org/poezio/slixmpp .

The still-open pull request that removes the current implementation can be seen here: https://github.com/Uninett/nav/pull/1889 .

The seventh maintenance release of the 4.9 series of NAV is now out!

The source code is available for download at GitHub.

New packages for Debian 8/9 (Jessie/Stretch) are available in our APT repository as usual. Please be advised that the Debian 8 package will be discontinued soon.

The Debian packages for NAV 4.9 have been rebuilt using dh-virtualenv, which means that most of the Python dependencies are now embedded into the packages themselves. If you have previously added a priority apt pin for packages from apt.uninett.no, you may now remove it, as there are no longer any other packages needed from that repository to run NAV.

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

The virtual appliance has also been updated.

Fixed GitHub issues in this release:

• #1882 (Invalid VLANs are generated from Juniper switches)
• #1920 (Provide a hook for adding extra information in the What-If tab in the IP Device Info page)
• #1946 (Vlans are categorized as linknets on Cisco Nexus with HSRP)
• #1953 (Adding new public filter in Alert Profiles fails)
• #1958 (NAV creates Graphite metrics with illegal characters in name)
• #1960 (Add option to control user administrator privileges from LDAP)
