Trunk links with LACP
by jaumeramos＠iesebre.com 07 Feb '20

07 Feb '20

Hi. First post here, hope it's the right place to ask questions. I'm trying NAV to document my network, it's a state college due to professional trainin with 600+ computers. My network equipment are mostly d- link switches, with mikrotik routers and some Cisco stuff. After enabling SNMP and LLDP i got an approximate map of the network, but the trunk connections using LACP protocol does not show in the map. Is there some additional configuration needed to make NAV detect them. Thanks for such a great piece of software.

Announcement: NAV 5.0.4 released
by Morten Brekkevold 16 Jan '20

16 Jan '20

The fourth 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 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. Changes ======= Fixed GitHub issues in this release: * #2074 ([BUG] ipdevpoll inventory job crashes for many devices with an AttributeError) * #2075 ([BUG] Editing existing API tokens shows no enabled endpoints) * #2076 ([BUG] Missing Javascript multiselect library used by Useradmin API token form) * #2077 ([BUG] string handling in snmptrapd is broken on Python 3) * #2081 ([BUG] Bulk importing netboxes without a managment profile raises an exception) * #2083 ([BUG] TypeError is raised when creating a csv for download from a room-search) * #2085 ([BUG] TypeError is raised when getting navlet) * #2087 ([BUG] Reports with many pages crash once page 4 is visited) * #2090 ([BUG] Marking machine as disabled in arnold raises TypeError) * #2092 ([BUG] ipdevinfo sensor tab produces too large Graphite request) * #2093 ([BUG] PortAdmin crashes when viewing a switch with non-ASCII port descriptions) * #2097 ([BUG] Adding a manual detention without a number of days until autoenable crashes Arnold) Please see the release notes [3] for more details. Happy NAVing everyone!

Portadmin - SNMP Error
by Ingeborg Hellemo 11 Des '19

11 Des '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 Des '19

02 Des '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?

Downgrade back to 4.9.8?
by Steve Kersley 14 Nov '19

14 Nov '19

Afternoon all, Is there a way to downgrade a Nav install to 4.9.8? Or will I need to blow away the database and start from scratch (no huge deal to be honest). Confession: I'm running it on Ubuntu rather than the recommended Debian. It got upgraded to 5.0.0, but as the Ubuntu LTS releases don't have a version of graphite-web that works with wsgi-python3 it's become an either/or, and I use graphite for storing other metrics as well as those from Nav. On attempting to pin the older version of Nav, it's failing to install because the database update script failed. Which I presume is because it had already upgraded the database for 5.0.0. I'm also toying after this to look at options of having Nav (and graphite and other services on this machine) as Docker containers simply to avoid version clashes in future. I see that Docker is listed as experimental, are there any particular issues to be aware of? Steve.

NAV netmap
by Erik 14 Nov '19

14 Nov '19

Hello, two questions on this part of NAV. 1. I have rooms which are in nested locations like "Address > Town > Country" but when I select "town" nothing shows in Netmap? Only selecting a room will show anything. I would have expected to show all which are below the nested set? 2 Is it possible to have a URL which wiil show a selected View in Full Screen directly so I can show it on a Dashboard monitor without manually having to select Full View? Cheers Erik
