Announcement: NAV 4.3.0 release candidate 1

We have a release candidate for NAV 4.3.0 ready to download for those
who want an early peek.

The source code is available for download at Launchpad [1]. A new
package for Debian Wheezy has been published in our APT repository, but
in the "navbeta" archive instead of the regular "nav" archive - modify
the instructions at [2] accordingly (We have no packages for Debian
Jessie yet, due to dependency problems and our own resource
constraints).

We have also published a "beta" Virtual Appliance on our homepage, if
you want to test the release candidate separately from your production
install (remember, there is no downgrade path!)

Changes
=======

This release makes some fundamental changes to NAV's data model to improve
support for non-physical devices (like Cisco VSS and Cisco VDC). Please read
the release notes [3] for further information.

User-visible features and improvements:

 * LP#744943  (Add switch to toggle display of traffic lines in Geomap)
 * LP#961212  (Show planned/active maintenance tasks for device in IP Device
               Info)
 * LP#1149160 (Auto-recognize HTTP URLs in reports and hyperlink them)
 * LP#1166695 (PortAdmin available from the toolbox)
 * LP#1169550 (NAV's data model should reflect modern reality, with virtual
               device support)

change map on geomap

Hello,

Is it possible to change the map in Geomap?
In our campus we have additional layers of openstreetmap it would be nice to
Integer.

Integration with GIS

Before I start doing such, I'm wondering if anyone has done any 
integration between NAV and a PostGIS based GIS system (mostly using 
QGIS for "frontend"), as I would rather add to existing work rather than 
repeating it...I thinking of just creating views in postgres referencing 
NAV data for the GIS to use to retrieve device inventory, status, and 
statistics in spatial queries. If it becomes successful and useful, I 
will do a writeup.

Setting up NAV from scratch/non-OVA (Graphite-issues)

Hi,

Decided to install NAV from 'scratch' (i.e. not use the OVA-package). Got NAV running fine, but had some
hiccups getting Graphite working as it should. Found no documentation on this what-so-ever (neither on
the NAV-pages, or the Graphite-pages), so had to try-and-fail some. Thought I'd share.

 - Debian Wheezy (not OVA)
 - NAV via apt (from https://nav.uninett.no/debian)
      root <at> tardis:~# dpkg -s nav|grep Vers
      Version: 4.0.1-3

1) Fixed /etc/nav/graphite.conf;
	base=http://localhost:8888/

2) Copied content of '/usr/share/graphite-web/apache2-graphite.conf' into own VHost;
	<VirtualHost localhost:8888>
	( + add NameVirtualHost + Listen in /etc/apache2/ports.conf)

3) Set 'CARBON_CACHE_ENABLED=true' in '/etc/default/graphite-carbon'
   Set 'ENABLE_UDP_LISTENER = True' in '/etc/carbon/carbon.conf'

5) Started carbon-cache (/etc/init.d/carbon-cache start)

6) Started NAV + apache

Is there a way to change the default 10 rows in the lists?

It should be useful if I can change the default 10 rows in the

"Show xx entries"

in the lists.

I searched through the configuration file and in the .js but I can't change
this.

I wish to put 50 rows or at least "all".

Thank you

You can't. All information in the interface table consists of
collected/detected information. Any changes made outside of NAV will
only be temporary.

If you would post details of your actual topology, where NAV is
mistaken, and add the details collected as described in [1], we may be
able to make a more qualified comment as to what may be happening. Feel
free to replace device names and text you would rather not divulge, as
long as you do it consistently.

Yes, this likely means the Carbon backend is not running, so NAV cannot
send its metrics to it. Please start the carbon-cache backend.

Re: Shutdown a port

Hi!

It is not possible to change the administrative status of the interface from
PortAdmin. The reason for this is that it simply has not been requested from the
NAV users.

The tool used for setting the interface administrative status is Arnold. The use
case for Arnold is that you have a mac- or ip-address that you want to shut out
from your network, so you search for that in Arnold and set the administrative
status of the resulting interface.

However, if you wish to manually set administrative statuses from PortAdmin,
that is something we can implement. Please register a bug for this on
https://bugs.launchpad.net/nav/+filebug and we will handle it.

Re: Problem with uplink detecion

NAV will traverse the path of each VLAN individually, starting at the
determined root router port for that VLAN. NAV does not get root
information from STP, but has detected which subnet prefix(es) are
routed on that VLAN, and uses this to detect the root router port. 

On the device connected to that router port (or on the same device, in
the case of an L3 switch), NAV will descend further on all trunks with
the current VLAN allowed, and non-trunks having this as their native
VLAN.

STP information is only used to find STP blocked ports. STP blocked
ports will not be traversed by the detector, only registered as blocked
on the VLAN that is being detected.

You mean a mismatch in the list of allowed vlans on each side of a
trunk? That would be logged as an error.

NAV mac-search with Nexus and FabricPath

Hi,

we have FP activated in our datacenter and use Cisco Nexus (5,6,7)k. I'm not sure what caused the problem but NAV can't find MAC-addresses on these devices and even on catalysts behind them anymore. I don't know what algorithm is used to figure out where a MAC-address is attached but maybe someone who knows can clarify what is needed for that to work?

Thanks in advance,
Mischa
