Announcement: NAV 5.0.3 released
by Morten Brekkevold 19 Dec '19

19 Dec '19

The third maintenance release of the 5.0 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. 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: * #2015 (Broken Mikrotik LLDP-MIB implementation causes ipdevpoll LLDP plugin to crash) * #2055 ([BUG] Navlets crash/appear blank if their config is stored as legacy pickles) * #2057 (Make servicemon run on Python 3) * #2058 ([BUG] navpgdump crashes with TypeError on Python 3 if exclusion options are provided) * #2059 ([BUG] Coriant Groove sensors names appear as reprs of bytes objects under Python 3) * #2060 ([BUG] smsd gammudispatcher error handling fails on Python 3) * #2061 ([BUG] silent_include tag template crashes any view that uses it) * #2062 ([BUG] ipdevpoll considers the same devices changed on every reload loop, causing massive scheduling problems) * #2063 (Massively reduce the number of queries produced by the API /alert endpoint) * #2065 ([BUG] some servicemon checker runs crash with a UnboundLocalError) * #2066 (Increase the max number of shown alerts in Status page to 1000 and provide feedback spinner when loading data) * #2067 ([BUG] Alertengine Slack dispatcher fails with TypeError) * #2068 ([BUG] Workaround for faulty Aruba ENTITY-MIB::entLogicalTable implementation crashes with TypeError on Python 3) * #2069 ([BUG] ipdevpoll inventory job crashes with a Django ValidationError) * #2070 ([BUG] Servicemon SMTP checker fails with " a bytes-like object is required, not 'str'") * #2071 ([BUG] Active maintenance task list crashes when tasks contain deleted IP devices) * #2072 ([BUG] Servicemon RadiusChecker always fails with "secret must be a binary string" message) * #2073 ([BUG] Room image upload crashes with a TypeError) Please see the release notes [3] for more details. Happy NAVing everyone!

Portadmin - SNMP Error
by Ingeborg Hellemo 11 Dec '19

11 Dec '19

NAV 4.8.6 We have a couple of switches, Cisco Catalyst 4510R+E where we are not able to change Vlan via PortAdmin: Error setting vlan: SNMP Error: wrongType (The set datatype does not match the data type the agent expects) We have several other switches of the same type where there are no errors. The config on the switches is as good as identical. Can anyone point us in the right direction for debugging this? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Upgrade Debian to Buster and NAV to 4.9.8
by René Romijn 02 Dec '19

02 Dec '19

Hi, We did an upgrade to a new VM, we installed Debian Buster and we installed NAV 4.9.8. After that we did a restore of the postgress db with navsyncdb, and we also restored the /var/lib/graphite directory to have the history of the graphs. But now if i reboot the new NAV server, the graphs are resetted tot he point we did the restore. In the console log we see this error: 16/09/2019 08:02:28 :: Unhandled Error Traceback (most recent call last): File "/usr/lib/python3/dist-packages/twisted/python/threadpool.py", line 250, in inContext result = inContext.theWork() File "/usr/lib/python3/dist-packages/twisted/python/threadpool.py", line 266, in <lambda> inContext.theWork = lambda: context.call(ctx, func, *args, **kw) File "/usr/lib/python3/dist-packages/twisted/python/context.py", line 122, in callWithContext return self.currentContext().callWithContext(ctx, func, *args, **kw) File "/usr/lib/python3/dist-packages/twisted/python/context.py", line 85, in callWithContext return func(*args,**kw) --- <exception caught here> --- File "/usr/lib/python3/dist-packages/carbon/writer.py", line 189, in writeForever writeCachedDataPoints() File "/usr/lib/python3/dist-packages/carbon/writer.py", line 98, in writeCachedDataPoints (metric, datapoints) = cache.drain_metric() File "/usr/lib/python3/dist-packages/carbon/cache.py", line 187, in drain_metric metric = self.strategy.choose_item() File "/usr/lib/python3/dist-packages/carbon/cache.py", line 116, in choose_item return next(self.queue) builtins.StopIteration: Is this easy to fix?
