NAV RAM Usage
by Studart UNI-RN 29 Jul '15

29 Jul '15

Hello guys, I'm running NAV 4.2 in a production environment here at the company I'm working for. I'm using Debian Wheezy (no graph interface installed) with 1GB of RAM and I have about 50 devices in the NAV seed database. I've noticed that almost all the the memory is already in use. It's no problem for me to increase it since it's in a virtual environment. But since I increase it I was just wondering if this is normal for NAV to use such amount of RAM memory. Thank you very much, -- Studart Tavares Analista de Redes Liga de Ensino do RN UNIRN - Centro Universitário do RN 55 84 3215-2917 (r 2818)

Some beginners questions
by Per Andersson 26 Jun '15

26 Jun '15

Hello! I have just started trying NAV, and is running it on a small part of our network at the moment, and have some questions: It finds our vlans and matches them with the correct prefixes but since we don't follow the convention for naming router interfaces the net ident and description fields is either empty (most common) or a bit confusing. Is there a way to edit them manually (directly in the database?)? Any other suggestions? If I want to enter cabling, in which "direction" is it supposed to be, should I enter the wiring closet as "Room" and the office as "Target" or the other way around? /Per Andersson Chalmers IT-department

Announcement: NAV 4.3.0 released
by Morten Brekkevold 19 Jun '15

19 Jun '15

The initial 4.3 series release of NAV is now out, with only minor changes and some bugfixes since the release candidate. A big thanks to those who helped test the release candidate! The source code is available for download at Launchpad [1]. A new package for Debian Wheezy has been published in our APT repository [2] as usual (We have no packages for Debian Jessie yet, due to dependency problems and our own resource constraints). The virtual appliance download has also been updated. 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) * LP#1242872 (Option to turn off traffic stats in Geomap) * LP#1248081 (New interface/tool to browse unrecognized neighbors) * LP#1366895 (Report widget) * LP#1421644 (Support Weathergoose traps from external temperature sensors) Bugfixes: * LP#1233093 (Report pages crash under psycopg2 >= 2.5) * LP#1397257 (Port Admin may not work properly for any non-HP and non-Cisco device) * LP#1447973 (CDP/LLDP neighbor matching fails when multiple ports match the identification) * LP#1447999 (Existing adjacency candidate data in db is not deleted if a device's CDP cache or LLDP remote table becomes empty) * LP#1448086 (Unable to identify LLDP neighbor's port in some instances) * LP#1458826 (1minstats job crashes on invalid ENTITY-MIB references from CISCO-PROCESS-MIB) * LP#1459138 (Ignore Cisco reserved VLANs when collecting BRIDGE-MIB data) * LP#1463724 (Increase frequency of module status verification) Happy NAVing everyone!

Django and Debian 8
by stutavares＠unirn.edu.br 08 Jun '15

08 Jun '15

Hi guys, I have a newly installed version of Debian Jessie and it doesn't install nav with the simple 'apt-get install nav'. One of the reason is the dependancy on Django, which is in version 1.7 in the packages repository. I read a post that says you are still working on this compatibility issue. Meanwhile what should I do? Wait for a new version of nav? Try and install an older verion of Debian? What are my options now to install a new nav in my network? All the best, Studart

Announcement: NAV 4.3.0 release candidate 1
by Morten Brekkevold 21 Mai '15

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!)

NAV and VLAN with Virtualized firewall
by Mattias Söderholm 13 Apr '15

13 Apr '15

Hi! I have a problem with VLAN auto discover. I have followed the guidelines with adding the router (firewall), but it won't get the VLAN info from it. The firewall is a software firewall (Sophos UTM) that's running in a Hyper-V cluster for HA . Could it be the software switch in the Hyper-V that's giving some problem or the firewall software? Before I also had some HP 2530 swithes added as an GWS. Then I got some VLAN info added to NAV, but NAV deletes the VLAN info in the SeedDB after a while and create it again with a new ID. So now I have changed the HP 2530 switches back to SW and hope the VLAN info will stay in SeedDB! But it would be great if I can get VLAN info to show up in Netmap. Is there some way to fix this if I can't get the info from the firewall? There is also a problem if you change a GWS to a SW, then ipdevpoll try to still collect ip2mac from the device but won't get the info and you end up with WatchDog reporting problems with ip2mac for that switch, The solution I have used is to go into the database and delete all post related to ip2mac for that device from ipdevpoll_log_job table. Is it a bug or am I doing something wrong here? Best regards Mattias
