Announcement: NAV 4.9.8 released
by Morten Brekkevold 22 Aug '19

22 Aug '19

The eighth maintenance release of the 4.9 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository [2] 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 is currently being updated at the time of this writing, and will be uploaded soon. Changes ======= 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) Please see the release notes [3] for more details. Happy NAVing everyone!

Changing VLAN / ports on Juniper EX
by Jean Benoit 20 Aug '19

20 Aug '19

Hello, We are looking for a solution to manage local networks. Our goal is to recommend a tool to local net admins. Most of our switches are Juniper EX, as cisco and HP switches are phased out. Our current tool, Netmagis, is slow to evolve on the network configuration side (we have not enough time to develop it). The network admin in one of our Faculty is currently testing Nav. He seems satisfied so far, except for one thing : the impossibility to set a VLAN on a port on Juniper through the "Port Admin" feature. Do you have any plan to allow VLAN modification on Juniper ? Thanks for your answer. -- Jean

Announcement: NAV 4.9.7 packaged for Debian 10 (Buster)
by Morten Brekkevold 01 Aug '19

01 Aug '19

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 [1]. 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. I suspect I'll be working on updating the appliance based on our production deployment configs of uWSGI. Hopefully, we can hopefully provide some config examples soon, for those who are interested in building their own deployments (of course, if you are already deploying Graphite on a separate server, this is a non-issue for you).
