Upgrade to NAV 5, navsyncdb barfs
by Ingeborg Hellemo 11 Mai '20

11 Mai '20

I'm in the middle of upgrading NAV from 4.8 to 5.0.5 and running 'navsyncdb' to alter the database schemas. (The database is named nynav because this is a test upgrade) /#navsyncdb Existing namespaces in nynav search path: "$user", public. Adding manage, profiles, logger, arnold, radius. Applying outstanding schema changes sql/changes/sc.04.09.0001.sql: OK sql/changes/sc.04.09.0050.sql: OK sql/changes/sc.04.09.0100.sql: OK sql/changes/sc.04.09.0110.sql: OK sql/changes/sc.04.09.0200.sql: OK sql/changes/sc.05.00.0001.sql: OK sql/changes/sc.05.00.0010.sql: operator is not unique: unknown || integer LINE 29: 'SNMP v' || snmp_version || ' read profile #' || row AS na... ^ HINT: Could not choose a best candidate operator. You might need to add explicit type casts. Server version Postgresql 9.6.17 Since this is a newly created database with imported data it might be missing some environment variables or something. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

LLDP Error / v5.0.5
by scorpion7 21 Apr '20

21 Apr '20

NAV v5.0.5 appears to have a problem in the topology/LLDP portion. The switch referenced below is a Cisco WS-3750X stack, running 15.2(4)E10. Referenced devices are [Ubiquiti] APs. FWIW – the switch does have such things as ARP inspection, DHCP snooping, etc. – enabled. 2020-04-13 06:23:35,227 [INFO plugins.lldp.lldpneighbor] [topo switch0.<obscured>] found multiple interface

have no issue this equipment combination of Cisco and Ubiquiti. Due to an odd issue, did end up dropping the VM and simply created a new one with latest Debian and latest NAV version, re-populating the equipment and configuration. Which may have been why certain things came to light? The Netmap doesn’t appear to be fully populated – suspect that it’s a cascading result of the above error?

Experience with NAV in large networks
by carsten＠strotmann.de 01 Apr '20

01 Apr '20

Hi, I'm evaluating NAV for one of my clients. As I have seen similar systems to NAV breaking down in large (> 100.000 devices) networks, I would like to know if anyone has experience with NAV in such large networks and how NAV scales in these networks. Anyone using NAV in such large environments? Greetings Carsten

website down?
by Steve Kersley 01 Apr '20

01 Apr '20

Morning, I can't imagine that you're not aware, but the NAV website has been down for the last few days. The documentation subsite is up, but the main site not. I'm guessing at the moment there are more pressing issues! Hope all NAV creators and users are well! Steve.

Announcement: NAV 5.0.5 released
by Morten Brekkevold 14 Mar '20

14 Mar '20

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 [1]. New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository [2] 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 reaches 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. Changes ======= 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) Please see the release notes [3] for more details. Happy NAVing everyone! Links ===== [1] https://github.com/UNINETT/nav/releases [2] https://nav.uninett.no/install-instructions/#debian [3] https://nav.uninett.no/doc/latest/release-notes.html#nav-5.0 -- Sincerely, Morten Brekkevold Uninett

Need to add devices manually?
by Michael Schwartzkopff 24 Feb '20

24 Feb '20

Hi, I am trying nav for the first time. I have a seed device. A LLDP neighbor us detected as "unrecognized neighbor". nav can access the device with SNMP. nav does not add this device automatically. Do I have to add the new device manually? Why does nav not add it automatically?
