Unable to upgrade nav 12 in debian 11 to any upper version.
by Secundino Grau 10 Des '25

10 Des '25

Hello, I have a fully working nav 5.12 instance and when I try to upgrade to 5.13, 5.14, 5.15, always have a lot of internal server errors 500 , and I'm unable to get graphite work again. If the process of upgrade is always within debian 11 packages, no success. I tested upgrading from debian 11 to 12, and then upgraded NAV but not success! Please, does anyone know if there are some steps in the upgrade process that I have missed? Thanks in advance, S. Grau

NAV 5.15.1 - My homepage broke
by Ingeborg Østrem Hellemo 09 Des '25

09 Des '25

Upgraded to 5.15.1 on my FreeBSD server and my homepage broke. In Chrome and Firefox no widgets are shown and the buttons/menus connected to dashboards are all over the place. See attachment. Edge is limping along, showing widgets, but with dangling search button and the other buttons as shown in the picture. I guess I am missing some htmx-stuff (perhaps not listed in requirements.txt) but I could need some help and pointers... --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no<mailto:ingeborg.hellemo@uit.no> Dep. of Information Technology --- Univ. of Tromsø

Announcement: NAV 5.15.1 released
by Morten Brekkevold 17 Nov '25

17 Nov '25

The first maintenance release of the 5.15 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 12 (Bookworm), 11 (Bullseye) and 13 (Trixie) are available in our APT repository. Please be extra aware of config file changes, especially in ipdevpoll.conf. Look out for *.dpkg-dist files in /etc/nav and make sure to update your running config. ## Fixed - Fixed crash reports being sent by unauthenticated clients accessing the API (#3650) - Fixed non-working port overviews for devices that contain modules with slashes in their name. A broken interfaces API endpoint caused both *ipdevinfo* and *interface browser* port lists to malfunction. (#3652) ## Release notes We always advise you to have a look at NAV’s accompanying release notes before upgrading. Happy NAVing everyone! ## Links [1] https://github.com/Uninett/nav/releases [2] https://nav.uninett.no/install-instructions/#debian [3] https://nav.readthedocs.io/en/latest/release-notes.html#nav-5-15

Locate IP address
by Einar Bjarni Halldórsson 10 Nov '25

10 Nov '25

Hi, I just setup NAV to test. I’m looking for a replacement for netdisco, which I’ve mostly used to track down IP addresses to switch+port. I’ve got NAV running and I added my switches and routers to the Seed DB. I can look for my workstations MAC address in machine tracker, but it doesn’t show the IP address. If I look search for the IP address it doesn’t find anything. Am I missing something, or does NAV only find IP addresses of switches and L3 connected devices to those? I know netdisco discovers IP addresses of L2 connected devices. Best wishes, .einar

Security announcement: NAV 5.13.1 released
by Morten Brekkevold 11 Jun '25

11 Jun '25

The first maintenance release of the 5.13 series of NAV is now out, and contains a security patch for a serious privilege escalation vulnerability in the web GUI. We recommend that all users upgrade as soon as possible. The source code is available for download at GitHub [1]. New packages for Debian 12 (Bookworm) and 11 (Bullseye) are available in our APT repository. Security ======== - Lock down API access for unprivileged users By default, NAV granted full API access to logged-in users, regardless of their configured privilege level. This would give unprivileged users access to manipulate NAV configuration and even elevate their own user privileges to administrator level. Read the full security advisory at https://github.com/Uninett/nav/security/advisories/GHSA-gprr-5vvf-582g Changed ======= - Update NAPALM dependency to 5.0 to keep NAV web GUI working (#2358) Fixed ===== - Fix filtering of 'Last seen' and sorting by 'Last active' in netbox interfaces view in room info (#3329) Release notes ============= We always advise you to have a look at NAV’s accompanying release notes before upgrading.

Time format is changed in NAV 5.13
by Ingeborg Hellemo 12 Mai '25

12 Mai '25

After upgrading to 5.13.0 we notice that the time and date format has changed from "2025-04-26 13:00:00" to "May 7, 2025, 1:36 p.m." Is this a deliberate change in NAV or a result of a change in a library? Most important: How can we get the old format back? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

NAV - Palo Alto Plugin: MAC Records Keep Expiring
by Mehmet E. Şahin (BAŞKANLIK-BİDB) 10 Des '24

10 Des '24

Hi Everyone, We started using the new Palo Alto plugin with excitement. It successfully retrieves the ARP table from the Palo Alto firewall as XML every 20 minutes. However, for some reason, while reading the ARP table from Palo Alto, the records are constantly expiring and being added again. This does not occur for the ARP records received via SNMP. Has anyone observed this situation? In the example below, the IP address 192.168.0.250 belongs to a server. There is no disconnection, but for some reason, the MAC tracker records show that a re-connection is happening every 20 minutes. (BTW - our nav version is the latest (5.10.2).) Best Regards Mehmet E. ŞAHİN

During upgrade I get "The automatic update script failed to update database"
by Davide Miccone 12 Nov '24

12 Nov '24

This is not the first time that happen. Upgrading to the latest 5.11 (from 5.9) I get error at the end. Inspecting nav DB it seems that DB has been updated. To check that DB has been updated I read the content of file cat sc.05.11.0001.sql, cat sc.05.11.0002.sql and check the DB for the presence of the table "manage.oui" and of the new records in the table "altertype". Below the error that I get: ===================== Automatic database update failed The automatic update script failed to update the database. Script output: could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?

Rather, the common approach would be to put the dead switch in maintenance mode in NAV. NAV will still attempt to monitor it, but any alarms about it will be suppressed. You can put a device on maintenance directly from the status tool by checking the checkbox next to the offending alert and selecting "Put on maintenance" from the actions drop-down menu. IIRC, this will create a maintenance task with no set end-time for that device. This also allows you to add a description/reason for why the device has been placed on maintenance. > Several Network Monitoring Tools (LibreNMS, CheckMK, Zabbix) let > disable a device.

Announcement: NAV 5.11.0 released
by Morten Brekkevold 03 Okt '24

03 Okt '24

The first feature release of the 5.11 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for 11 (Bullseye) are available in our APT repository as usual. We haven't started building packages for Debian 12 (Bookworm) yet, as NAV does not yet support running under Python 3.11. Please be extra aware of config file changes. Look out for `*.dpkg-dist` files in `/etc/nav` and make sure to update your running config. Removed ======= - Dropped support for Python 3.7 (#2790) Added ===== - Post lifecycle event when power supplies or fans are removed (#2982) - Post lifecycle event when a module or chassis is deleted via the status or device history tools (#2983) - Database model for representing Organizationally Unique Identifiers (OUI) to identify vendors for MAC addresses - Script for populating database with OUIs and corresponding vendors from IEEE (#2945) - Module for generating JWTs (#2948) - Documentation for configuring and using JWT tokens in NAV API (#2618) Changed ======= - Upgraded dependencies after dropping support for Python 3.7 (#2790) - Changed Sphinx version to 7.4.7 (#2826) - Changed required PostgreSQL version to 13 (#2892) - Moved the test suite's web crawler complexity away from the test discovery phase to the test phase itself. This reduces the number of generated test cases from N to 2 (where N is the number of reachable NAV pages) (#2966) - Link to the doc for using docker for development from the README and mention what ports are used when using docker for development (#2978) - Many user-facing forms of the web user interface have been refactored in order to remove a dependency that keeps NAV incompatible with Python 3.11. This should not affect looks or functionality. This work is still ongoing in the master branch and we hope it will be complete by NAV version 5.12. Fixed ===== - Correctly delete an IP Device's existing function value when empty field value is submitted in the IP Device IP Device edit form (#2269) - Fixed crash bug when reordering filters within a filter group in Alert Profiles (#2979) - Fixed IPAM API crash bug that caused unnecessary error reports sent as e-mail to site admins (#2989) - Fixed bad tooltip grammar in ipdevinfo "degraded aggregate link" badge - Make the test suite easier to run under MacOS - Skip tests when 3rd party requirements are missing, instead of outright failing Security ======== - Ensure that CSRF token info is preserved when refactoring crispy forms to non-crispy equivalents. This means that flat_form.html and _form_content.html templates will include CSRF token info if form method is set to POST. (#3056) Release notes ============= We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. Happy NAVing everyone!

Performance questions and weathermap
by Manuel Marín 08 Jul '24

Dear NAV community We are looking for a network monitoring platform as a replacement to cacti/weathermap and I was wondering if there is information about performance/hardware requirement for a network with ~20K networks devices. Can NAV support this number of devices? It would be great if someone can share their experiences running NAV with large networks. Thank you!

navtopology is already running
by Ingeborg Hellemo 21 Mai '24

21 Mai '24

NAV 5.9.1 Suddenly, since yesterday, a lot (but not all) of the navtopology cron jobs sends an email with "navtopology is already running" An example: /var/log/cron Apr 30 09:35:00 <hostname> /usr/sbin/cron[69867]: (navcron) CMD (navtopology --l2 --vlan) 10 minutes later an email arrives Date: Tue, 30 Apr 2024 09:43:35 +0200 (CEST) Subject: Cron <navcron@bjarne> navtopology --l2 --vlan navtopology is already running (69867) What can trigger this error? var/log/navtopology shows that the job runs as usual. (Last lines in the run is "deleting unused prefixes/vlans") The one thing that changed before this error turned up is that the server running NAV was moved behind Cisco ACI and a (application centric) firewall. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Closing down our IRC channel
by Morten Brekkevold 13 Mai '24

13 Mai '24

Hi everyone! We regret to inform you all that we will be closing NAV's official IRC channel on Libera.Chat by the end of this week. The IRC channel has seen very little activity these last few years, and it's harder to have the younger engineers on our team engage in IRC as a community tool. It seems I'm the only one from our team hanging around the channel, so by "closing" we really mean that I will stop paying attention to the channel, and the navbot will be taken down. Given the activity level of the IRC channel, we don't think anyone will miss it much. Going forward, we encourage you to use the discussion boards on GitHub [1] as a replacement, or just keep using this mailing list :) [1] https://github.com/Uninett/nav/discussions -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research

Ways to limit or disable the newly introduced PoE feature in Portadmin

Hi, We just recently upgraded to 5.8. Congrats on the SNMPv3 implementation! However, the new possibility to set PoE on the ports via Portadmin gives us some headaches. We only (if ever) want to allow this feature on certain ports for certain users. Is there a way to limit or disable this feature?

NAV 5.7.1 FreeBSD 12.4 Python 3.9 When visiting /alertprofiles/profile/ and choosing "Deactivate" on a profile we get an error. Since this is not something we do every day I'm not sure if this began after upgrading to 5.7.1 or if it has been broken for a while.

nav installation
by Kejvan Redjamand 13 Okt '23

13 Okt '23

Hi, I have had problems installing nav 57.1-2 on a Debian 11 from NAV repository with 'apt install nav'. The installation give the following warning, you have the choice to click OK. Database initialization failed │ │ Script output: │ │ Traceback (most recent call last): │ File "/usr/sbin/navsyncdb", line 2, in <module> │ from nav.pgsync import main │ ModuleNotFoundError: No module named 'nav' <Ok> It is not possible to run "sudo -u postgres navsyncdb" after the installation either, same error message, for the same reason as above. I found that the symlinks are setup somehow wrong for nav binaries installed. I'm not a good python programmer but probably the virtual env is not setup or configured as it should. /opt/venvs/nav/bin# ls -l python* lrwxrwxrwx 1 root root 16 Sep 18 14:09 python -> /usr/bin/python3 lrwxrwxrwx 1 root root 6 Sep 18 14:09 python3 -> python lrwxrwxrwx 1 root root 6 Sep 18 14:09 python3.9 -> python because in my case: /usr/bin/python3 -> python3.11 And ### /opt/venvs/nav/pyvenv.cfg home = /usr implementation = CPython version_info = 3.9.2.final.0 virtualenv = 20.4.0+ds include-system-site-packages = false base-prefix = /usr base-exec-prefix = /usr base-executable = /usr/bin/python3 So I chnged base-executable to /usr/bin/python3.9 And the links to /opt/venvs/nav/bin# rm python /opt/venvs/nav/bin# ln -s /usr/bin/python3.9 python So everything points to Python 3.9.2. Now with every attempt for installation of any package I get: Configuring nav │ │ Attempt to modify config file /etc/nav/db.conf failed │ │ │ Script output: │ │ <Ok> It seems that dpkg wants to run post installations and something goes wrong.

I am out of ideas and any help is appreciated. Fixing the instalation scripts or Python venvs is it possible to do? Kind Regards, Kejvan

Setting device group for a device through API
by Håvard Ose Nordstrand 15 Sep '23

15 Sep '23

Hi! We're using a Python script to import devices from a Cisco DNA inventory, but I can't seem to find a way to set a device group for the devices through the API. I'm using PATCH with the "/api/1/netbox/{netbox_id}/" endpoint, but as far as I can understand from the source code, it only supports certain special attributes like "organizationid", "roomid" etc. and not arbitrary device attributes. Is this implemented? If not, would it be easy for me to implement a new API endpoint attribute for this or would this tie into a lot of other things? -- Med vennlig hilsen Håvard Ose Nordstrand Overingeniør – Faggruppe Nett NTNU IT, Drift [cid:8e2b2110-e280-4f3f-8c21-434fb33f3b8b]

Alert profiles : how to read/check filters values ? set schedules ?
by FOUR Ludovic (EXT) 15 Sep '23

15 Sep '23

Hello, With the last version NAV 5.7, we can now create filters and raise alarms from Juniper chassis led (red or yellow) in the alert profiles. Thank you :) I'm trying to create new filters, but I can't check if it works really Can we list the values of all filters somewhere, for each device ? (Psql request ?) I trying to create an alert profile to send specific alarms at specific time for a specific group of users In my test profile, I can add a time period and choose start time (with valid format HH:MM or HH), and add subscriptions. In profile details the time periods valid during is 07:30 - 07:30 I don't know how to set a schedule from my subscriptions, for example from 7:30am (7h30) to 9pm (21h00) in weekdays.

VLANs from PaloAlto router ports missing
by Philipp Petermann 03 Jul '23

03 Jul '23

Hi, At our university we use the portadmin "vlan_auth" feature to restrict access to certain VLANs for certain organizations. Now we have the problem that a VLAN that we want to give access to is missing in NAV and we couldn't find a way to just add this VLAN. From what I understand VLANs are added automatically by ipdevpoll from detected router ports. Now the reason for this missing VLAN most probably is the fact that it is routed on a PaloAlto firewall. This firewall exists in NAV as type "Palo Alto Networks PA-5200 (Palo Alto Networks PA-5200 series firewall from PaloAlto)" (sysobjectid 1.3.6.1.4.1.25461.2.3.23) but no router ports are reported (count 0). So my questions at this point are: - Is there a way to manually add VLANs so the can be used by "vlan_auth"? - Is my assumption correct that the VLAN is missing because the PaloAlto router ports are not correctly detected? - Should PaloAlto router ports normally be detected with NAV? - If so, how can I fix this? And if not, is there any workaround available? - Is https://github.com/Uninett/nav/pull/2613 a solution to this? We are currently using NAV 5.5.2 Thanks and best regards, -- Philipp Petermann Universität Basel | ITS | NINS Spitalstrasse 41 | 4056 Basel | Schweiz Tel. +41 61 207 15 74

pping.conf - does groups_excluded= work?
by Ingeborg Hellemo 25 Mai '23

25 Mai '23

pping.conf lets you spread the pping-task over several hosts via the use of groups_included and groups_excluded. We use this feature because we have some hosts only reachable through a tunnel. The groups_included works fine: Our second pping-host only pings the host in the device group specified. But our main NAV host still pings all hosts, even though the exact same device group is listed in groups_excluded. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Netmap is empty
by onygaard＠tryggheim.no 24 Feb '23

24 Feb '23

Hi, We are running NAV 5.6.0 (from av Debian package) on a local Debian 11 machine, set up with postgresql and apache2. Initially we had some problem with the error message "Graphite unreachable", but followed the solution suggested by datagutten: https://github.com/Uninett/nav/discussions/2535 Now, a lot looks nice. Graphs display fine, but we have problems with Netmap, which is empty. For the router e.g. the "Ports" tab is missing info about "To Device" and "To Port". "Port details" do not provide any options for "Two IP device". Regards, Ole Harald

Alert Profiles, filters and options
by BERGELIN SABADELL, IVAR-ERIC 16 Feb '23

16 Feb '23

Hello, My name is Ivar and I work at Universitat Pompeu Fabra of Barcelona. I sent an email a few days ago asking about the API's options of NAV (no responses yet). Now I'm trying to get the link status of a switch using filters, but I have three questions. - Is it possible to get this information using filters? My idea is to send a daily email with a list of the ports of a specific switch which has link status down through NAV's "Alert Profiles" tool. - What is the difference between these two tabs? [image: image.png] [image: image.png] - Is this second option checking if a port has an ethernet cable plugged to the ethernet card of a computer at that moment?

Fwd: A question about computers connectivity
by BERGELIN SABADELL, IVAR-ERIC 16 Feb '23

16 Feb '23

Hello, My name is Ivar, I work at Universitat Pompeu Fabra of Barcelona and we use NAV 4.5.2. I have a question about the NAV's API functionalities. We are looking to see if it's possible to check whether a group of computers connected to a specific switch have "link signal status" even when they are turned off (all the computers have WOL enabled as well). I found an example to get the state (active) of a computer. Here in this following link of your documentation URL: http://navscc-upf.x.upf.edu/doc/howto/using_the_api.html You show a specific scenario titled: We want to know the interface a computer is connected to right now. We have the ip-address of the computer. So, when it says "We want to know the interface a computer *is connected to right now*" means the computer is turned on or it works even if the computer is off? it would help us a lot. Thank you. -- *Ivar Bergelin* Tècnic de suport informàtic Unitat d'Informàtica del Campus del Poblenou Roc Boronat 138 | 08018 - Barcelona [Tel.] (+34) 93 542 23 58 http://www.upf.edu

The row index is given as `.1.10.0.2.49.143`. The `.1` indicates an address type of IPv4, which according to spec should occupy 4 octets. However, the remaining row index contains 5 octets - An invalid IPv4 address: `10.0.2.49.143`. This is the type definition: > InetAddressIPv4 ::= TEXTUAL-CONVENTION > DISPLAY-HINT "1d.1d.1d.1d" > STATUS current > DESCRIPTION > "Represents an IPv4 network address: > > Octets Contents Encoding > 1-4 IPv4 address network-byte order > > The corresponding InetAddressType value is ipv4(1). > > This textual convention SHOULD NOT be used directly in object > definitions, as it restricts addresses to a specific format. > However, if it is used, it MAY be used either on its own or in > conjunction with InetAddressType, as a pair." > SYNTAX OCTET STRING (SIZE (4)) This response perfectly explains the warning/error given by ipdevpoll: > device has strange SNMP implementation of IP-MIB; ignoring retrieved IP > address data: IPv4 address length is not 4: OID('.1.10.0.2.49.143') It seems to me like the Fortigate device appends an actual `ifIndex` value (143, in this case) to all the IP addresses, and is therefore in violation of the MIB definition. We could potentially work around this in NAV by ignoring the extra data and just interpret the first four octets, but this might cause problems with other devices that have faulty IP-MIB implementations, or it could cause potential problems if the same IP address appears multiple times with different ifIndex values attached to it. I would at the very least report this as a bug to Fortigate. -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research

Correcting NAV topology after a physical reconfiguration
by tom.daae＠lom.kommune.no 21 Des '22

21 Des '22

Hi, I'm a new user of NAV and have found it to be a very useful tool. Among other things, it has helped us discover and plan improvements to our network topology. After implementing said improvements however, I find myself in a bit of a predicament. Two of my switches were previously connected via a link (in practice a daisy-chain), which is no longer physically present. NAV, of course, does not know the difference between a link that is temporarily down and one that is never coming back up, so the link remains in our netmap. I have not found a way of removing this link from NAV, short of deleting and re-registering the switches on either end of the link. This would of course mean losing a lot of traffic stats, so I'm wondering if there is any way to tell NAV do forget this specific link? Am I just misunderstanding something fundamental here?

Look out for `*.dpkg-dist` files in `/etc/nav` and make sure to update your running config. The virtual appliance will be updated, but currently, the automated GitHub workflows aren't working due to changes at GitHub. Fixes ===== - Delete and ignore module devices with fake serial number `BUILTIN`, as reported by Juniper equipment, in order to avoid spamming with `device[SFH]wUpgrade` alerts (#2491, #2492) Release notes ============= We always advise you to have a look at NAV's accompanying release notes [3] before upgrading. This maintenance release was made to fix an ugly issue for those who monitor Juniper equipment using NAV (of which there are quite a few). We've added the following note: Juniper ``BUILTIN`` devices --------------------------- Juniper equipment tends to report soldered-on linecards as field-replaceable modules through their implementation of ``ENTITY-MIB::entPhysicalTable``. These modules are also all reported as having the same serial number: ``BUILTIN``. NAV versions prior to 5.5.1 did not safeguard against this Juniper bug. This would cause NAV installations that monitor Juniper equipment to have a single device with the ``BUILTIN`` serial number, which was shared between all monitored Juniper netboxes. The attributes of ``BUILTIN`` devices (such as software or firmware revision) would be different across most Juniper netboxes, causing them to compete for updates of the attributes in the NAV database. This went under the radar until NAV 5.5.0 re-introduced the ``device*Upgrade`` set of alerts. Now, every time a Juniper netbox is polleed and the shared ``BUILTIN`` device's software/hardware/firmware revision was changed, an alert would be generated. For those unfortunate enough to subscribe to all NAV alerts, this would lead to a storm of alerts. Subsequently, NAV 5.5.1 deletes this shared ``BUILTIN`` device from the database, and adds functionality to ignore any module or entity that reports this as its serial number. Happy NAVing everyone!

Nav - LLDP Missing on some FS model
by Marco Valerio Bifolco 03 Nov '22

03 Nov '22

Hello, First of all thanks for your job, we really appreciate nav solution. We noticed that some of our FS.COM switch, (we got, cisco, hp, dlink, fs) does not work as expected. Nav doesn't get LLDP information, and for this it is wrongly populating the net map. The FS model working properly are s3900, s5850; But not so lucky with s2800, s1400, s3400 . It's possible to force nav to choose a neighbor from cam candidate? Or set it manually? Or is it possible to make these switch works with nav? Maybe passing mib somehow? Many Thanks in advance Best Regards [cid:image001.png@01D8D356.6C245C00] Marco V.

This installation was first started in NAV 3.x era (2012) and continually upgraded and moved to different hardware a couple of times, so it is very possible there is junk in the configs that is no longer relevant [Tue Sep 27 08:48:55.649027 2022] [wsgi:error] [pid 541:tid 140035050575616] [remote 127.0.0.1:35090] [Tue Sep 27 08:48:55 2022] [WARNING] [pid=541 nav.web.auth] User default denied access to /tags/tagMultiSeries

Re: wrong Port configuration status for juniper device if port manually disabled

Hello, I just forgot to reply to all, my bad sorry I leave all the comments below I took a look into ipdevpoll.log When I'm updating a port, there is new [INFO schedule.netboxjobscheduler] line into ipdevpoll log, means that the scheduler is doing fine. I still have the same issue with portadmin enabled checkbox : if you uncheck enabled box, save, then reload page, the checkbox goes back to checked, and remains in this state. - but it updates the interface - (disabled) I've made some setup to portadmin.conf, and changed link_edit = false (better not cut the tree branch where you are sitting on) but I don't think it's related to.

What ports NAV knows about is only updated by the inventory job, which runs every 6 hours. However, ipdevpoll does show some restraint from deleting any interface as soon as it appears missing (some devices can be wonky) - it actually marks it internally with a "missing since" timestamp, and removes it only when it remains missing after certain amount of time. I don't recall the exact amount, but I'm guessing 24 hours. > Maybe a SSL cache issue on server side ? > I'm using standard apache mod ssl settings > SSLSessionCache shmcb:${APACHE_RUN_DIR}/ssl_scache(512000) > SSLSessionCacheTimeout 300 No, this is unrelated to content caching. -- Sincerely, Morten Brekkevold Sikt – Norwegian Agency for Shared Services in Education and Research

wrong Port configuration status for juniper device if port manually disabled
by FOUR Ludovic (EXT) 30 Mar '22

30 Mar '22

Hello, I found a problem wih NAV portadmin configuration page for Juniper EX series I ran wildcard changes to unused interfaces, and I disabled them manually with junos set command [ set interfaces <port number> disable ] However, in the NAV portadmin page configuration, the port status of those interfaces is still enabled. (checkbox checked) Interface => NAV: enabled / JunOS: disabled When I uncheck the enable checkbox, and save changes, the NAV portadmin page show disabled, and the port is still disabled in junos console. Interface => NAV: disabled / JunOS: disabled If enable and save changes again into NAV, and the port is next enabled in console. Interface => NAV: enabled / JunOS: enabled If I manually update the interface description with junos set command, and update NAV portadmin page, the description field is updated. Does NAV run netconf or snmp checkings before showing the portadmin page, or it does only rely on last database readings for portadmin state ? It makes some confusion, because we think the interface is enabled and working into NAV portadmin page, but it's not in reality. Regards, Ludovic FOUR SSI DR10 CNRS - Support Infoprox Pharma FRANCE

NAV - Palo Alto ARP table import for Machine Tracer
by Mehmet E. Şahin (BAŞKANLIK-BİDB) 28 Jan '22

28 Jan '22

Hi Everyone, We have NAV to monitor network switches and also Palo Alto Firewall. We can only use Palo Alto api to query its arp table as it does not support it over snmp. Could there be a way to import those ARP records from palo alto firewall to NAV periodically ? We are asking this because the machine tracer tool on NAV is very useful and would be great if those arp recods from palo alto to be imported to the NAV. Best Regards Mehmet Emin Şahin

How to add sensorgateway probes to nav ?
by FOUR Ludovic (EXT) 17 Des '21

17 Des '21

Hello, I'm using NAV 5.2 and I would like to add a couple of Serverscheck temperature probes that monitor our network racks Product reference is detailed here : https://serverscheck.com/sensors/baseunit.asp I'm trying to add the probes by following the adding AKCP probe tutorial. I made this : 1/ Translate the sensorgateway.mib into SERVERSCHECK-MIB.py with smidump command 2/ Copy the python file to folder /opt/venvs/nav/lib/python3.7/site-packages/nav/smidumps There's a ServersCheck module used in MIB file, that i'm using to interrogate directly the probe I can get the temperature value with snmpwalk -c community -v1|2c <IP of the probe> ServersCheck:sensor1Name.0 If I translate into OID with snmptranslate command, I get this OID .1.3.6.1.4.1.17095.3.2.0 3/ Create the file serverscheck_mib.py with those lines to /opt/venvs/nav/lib/python3.7/site-packages/nav/mibs from twisted.internet import defer from nav.mibs import reduce_index from nav.mibs.mibretriever import MibRetriever from nav.smidumps import get_mib class ServerCheckMib(MibRetriever): mib = get_mib('SERVERSCHECK-MIB') @defer.inlineCallbacks def get_all_sensors(self): result = [ { 'oid': '.1.3.6.1.4.1.17095.3.2.0', 'unit_of_measurement': 'celsius', 'precision': 1, 'scale': None, 'description': "Ambient temperature", 'name': "Ambient temperature", 'internal_name': "Ambient temperature", 'mib': 'SERVERSCHECK-MIB', } ] defer.returnValue(result) - Add the following lines to /etc/nav/ipdevpoll.conf (note sure of iana code of serverscheck manufacturer. should be 25432) 25432 = ServersCheckMib SERVERSCHECK = SERVERSCHECK-MIB At this point i'm stuck (ipdevpoll log empty) and I still can't get sensors readings into NAV and it doesn't recognize the probe type into collected info of the seedDB probe page Any ideas of what I'm doing wrong ?

advice on upgrading nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11
by Mischa Diehm 10 Des '21

10 Des '21

Hei all, we have a larger NAV setup with a bit more than 1000 Cisco Switches and use quite a lot of the features supported in NAV. Since our setup is a bit dusty we plan to upgrade (nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11). I wanted to ask for your advice on the upgrade paths possible. We use a external db server that hosts the postgres db. Requirements/Whishes: - it would be great to keep the devices history and graphs so a simple dump.py and reinstall would be a bit lossy - it would be nice to start with a fresh installed debian 11. Is there a good/preferred path that we could follow? Thanks for any ideas and suggestions, Mischa p.s.: Any ideas / timeframe when nav will release debian 11 packages? -- narrowin.ch /\ network & security

LDAP / ActiveDirectory issues
by Andrea Verni 02 Sep '21

02 Sep '21

Hi, I deployed NAV 5.14 on a debian 10 VM and configured LDAP authentication as from https://nav.readthedocs.io/en/latest/reference/ldap.html?highlight=ldap - however if using LDAP the login works randomly (need to try 2 to 5/6 time to login) while LDAPS never works. I did a test with ldapsearch on the same VM using both LDAP and LDAPS and both works so no issues with basedn or manager credentials nor with certificates. Is anyone else experiencing the same issue ? Other LDAPS based applications we use internally sucessfully connect to same AD servers. Anyone can help maybe? Thanks! Andrea

Analyze gaps in Port metrics
by René Romijn 20 Apr '21

20 Apr '21

Hi, What is the best way to analyze gaps in the graphs in the port metrics? Since a couple of weeks we have at random some gaps in the graphs. It doesn't look like network errors, because it also happens on some core routers where we have no problems with it at all. Kind regards, René.

Is it possible to put an interface on maintenance?
by Ingeborg Hellemo 02 Feb '21

02 Feb '21

One of my users is doing work on a netbox and links are down. He clicks on the link in /status, ends up on /ipdevinfo/<boxname>/interface=nnnnnnn, chicks Recent Alerts and observes an Unresolved linkState event. He then clicks on the Message and endds up in /search/event/nnnn "Event details" Under Available actions he chooses "Put on maintenance". Is this supposed to work for interfaces? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

ipdevinfo shows empty Function-field for some hosts
by Ingeborg Hellemo 16 Des '20

16 Des '20

NAV 5.1.1 I have so far discovered two devices where /ipdevinfo shows "Function N/A", but "Edit IP device" (and database queries) shows that data is present. The only "special" character is hyphen, but other devices with hyphen in the Function string displays them correctly. I have also tried to change the Function string, but still displays as N/A How to debug? It also seems like it is impossible to empty the Function field (both on these two devices and others I have tried.) If you delete what's written and clicks Save the text reappears. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Routerports?
by Jan Astrup 19 Aug '20

19 Aug '20

Hello, I'm new to the nav-system, but i must say i like it alot. However, I'm having issues with a few devices, primarily ubiquiti and cambium wireless access points and CPE's. None of their ports come up as router ports, which in my case i think would be needed in order to get all my links visible on the geomap(?). Also, none of the ports are "patchable", so I can't create patches and assign them to those devices. Any pointers in where i should start looking in order to get this issue fixed? Best regards, Jan Astrup

NAV auth with LDAP and MS AD
by Ingeborg Hellemo 05 Jun '20

05 Jun '20

We have had our own local patch which authenticates via Radius, but the time has come to move in the direction of LDAP and MS AD. [ldap] enabled = yes server = dc10.ad.uit.no port = 636 encryption = ssl uid_attr = sAMAccountName basedn = ou=people,dc=uit,dc=no lookupmethod=direct suffix = @ad.uit.no debug = yes I get authentication to work with an existing account, but can not create a new account. The debug-log shows a strange ldap url during referral: It begins ok: ldap_url_parse_ext(ldaps://dc10.ad.uit.no:636) ... connect success But then: ldap_chase_v3referrals ldap_url_parse_ext(ldaps://uit.no/ou=people,dc=uit,dc=no) Where does the domain uit.no in the URL come from? Is there a config setting I have overlooked? This of course ends in Unable to chase referral "ldaps://uit.no/ou=people,dc=uit,dc=no" (-1: Can't contact LDAP server) (If I use "lookupmethod=search" the webpage throws an error and no account is created. If I use "lookupmethod=direct" the account is created, but without Name, because that was not found in the search - since it was sent to the wrong server) --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Issues with Nav docker container - logs, graph gaps and high postgres utilization
by Steve Kersley 03 Jun '20

03 Jun '20

Morning, TLDR: Gaps in graphs after Nav container running for a day or two. Nav container doesn't create logfiles. Nav postgres container has lots of postgres processes running, consuming ¾ of host CPU. Is this normal or bug (in container, or with my setup?) So, after killing my old Nav system with a series of conflicting upgrades, I decided to embrace the Docker approach, so that Nav (and other services) would be self-contained and not affected by upgrading components. All was initially well, but I'm starting to run into increasing graph gaps that I've not been able to resolve. If I stop and rebuild all of the containers with docker-compose, all seems well to start with, but after a while (few hours to a day or two) I start to get gaps and then it's downhill from there. The next issue I discovered while looking into the graph gaps is that there are no logs. Docker does mount a volume on /var/log/nav (from the dockerfile) but nothing ever gets created in it, meaning it's hard to look for warnings or errors. Is that expected behaviour, or is it something I got wrong when adapting the docker-compose file? The only logs I get from 'docker logs' show smsd being spawned and exiting every second: 2020-05-28 07:29:19,089 INFO spawned: 'smsd' with pid 28112 2020-05-28 07:29:20,092 INFO success: smsd entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 2020-05-28 07:29:20,560 INFO exited: smsd (exit status 1; not expected) 2020-05-28 07:29:21,563 INFO spawned: 'smsd' with pid 28116 2020-05-28 07:29:22,565 INFO success: smsd entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 2020-05-28 07:29:22,971 INFO exited: smsd (exit status 1; not expected) 2020-05-28 07:29:23,975 INFO spawned: 'smsd' with pid 28118 2020-05-28 07:29:24,977 INFO success: smsd entered RUNNING state, process has stayed up for > than 1 seconds (startsecs) 2020-05-28 07:29:25,355 INFO exited: smsd (exit status 1; not expected) (looking into this, appears to be exiting because python-gammu is not configured in the container, but is unlikely to be connected to the issue) I did increase UDP receive buffers on the host, which I first thought had solved the issue, but the improvement was a side effect of restarting all of the containers and reverted to gaps later. Nav's seeddb has 65 devices. Almost all just switches, with a handful of vmware hosts. The job durations are peculiar too - the 1minstats job for instance, on some switches takes a couple of seconds to run. On others, nearly a minute (or often several minutes on one in particular), but whether that's the cause or a symptom I don't know. It looks as though the postgres database used by Nav is what's eating resources and presumably causing the graph gaps. The docker host typically has a load average of 9-12. Looking at the processes, there are typically at least 10 postgres processes running in the NavDB container, continually using 20-30% of CPU for each process. This does not seem normal to me? I also gave that container more shared memory, as it was logging occasional errors about not being able to allocate enough. Again no change - worse if anything. The docker host is running as a VM as an in-production 'test' - in the fullness of time (when I'm not remote working), I'll likely move the containers onto a bare metal host. Docker host has 4 cores and 8Gb allocated, and is not hitting swap, but I can increase both. The vmware host it runs on has plenty of CPU and RAM with not a massive amount running on it, and the docker host is running from an array of SSDs. Besides Nav and NavDB containers, it's running containers for Icinga, and the Icinga backend mysql database; a dedicated shared graphite container accessed by both Icinga and Nav; Grafana as a dashboard for both; and nginx as a web proxy for all services. (Previously these services were all running fine alongside each other on a physical host of similar specification, until conflicting dependencies broke things). Does anyone have any thoughts?

Monitor Paloalto equipment
by Edgar Matias 03 Jun '20

03 Jun '20

Hello NAV community, I recently added a Paloalto firewall to the NAV to be monitored. This is the gateway for some vlan. NAV lists all interfaces, but does not classify them as routing or switching ports. There are other things that are not recognized as power supply sensors, for example. I believe this is because the NAV does not have specific MIBs configured. Is there a way to import MIBs to this specific device, or a workaround ? Thanks in advance. Great tool ;) -- Edgar Matias Application Infrastructures Area Fundação para a Ciência e a Tecnologia Unidade FCCN – Computação Científica Nacional Av. do Brasil, 101, 1700-066 Lisboa, Portugal T: [+351] 218 440 100 | [+351] 900 000 000 www.fccn.pt

Upgrade to NAV 5, navsyncdb barfs

I'm in the middle of upgrading NAV from 4.8 to 5.0.5 and running 'navsyncdb' to alter the database schemas.

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.

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?

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.

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.

Announcement: NAV 5.0.1 released
by Morten Brekkevold 05 Des '19

05 Des '19

The first 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: * #2016 (ipdevpoll inventory job crashes when processing manufacturing dates from ENTITY-MIB under Python 3) * #2019 (IP Device info "Neighbor" tab is blank) * #2023 (Netmap layer 3 crashing) * #2025 (SeedDB bulk import file upload crashes) * #2030 (Ensure internal snmp agent check state stays in sync with global snmpAgentState) * #2031 (Fix PortAdmin crash on invalid IP search) * #2032 (Replace SNMP community columns in SeedDB netbox listing with management profile lists) * #2033 (Don't crash when logging in users with old-style password hashes) Please see the release notes [3] for more details. Happy NAVing everyone!

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.

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?

Changing VLAN / ports on Juniper EX
by Jean Benoit 20 Aug '19

20 Aug '19

Hello, We are looking for a solution to manage local networks. Our goal is to recommend a tool to local net admins. Most of our switches are Juniper EX, as cisco and HP switches are phased out. Our current tool, Netmagis, is slow to evolve on the network configuration side (we have not enough time to develop it). The network admin in one of our Faculty is currently testing Nav. He seems satisfied so far, except for one thing : the impossibility to set a VLAN on a port on Juniper through the "Port Admin" feature. Do you have any plan to allow VLAN modification on Juniper ? Thanks for your answer. -- Jean

Announcement: NAV 4.9.7 packaged for Debian 10 (Buster)
by Morten Brekkevold 01 Aug '19

01 Aug '19

Hi everyone, this is a two-fold announcement: 1. We have, as of today, published a NAV 4.9.7 package for Debian 10 (Buster) in our regular APT repository [1]. 2. As previously mentioned, we are now discontinuing support for the Debian 8 (Jessie) line of NAV packages. There will be no new updates for this outdated platform from our side. There is, however, one caveat to using the NAV package on Debian 10: If you want to serve both the NAV web UI and Graphite-web from the same server, you cannot achieve this on Debian 10 using the regular Apache + mod_wsgi method for both applications. Debian 10 ships with a graphite-web package that runs on Python 3, while NAV 4.9 does not support Python 3 (we expect the next feature release to run on Python 3). mod_wsgi cannot be made to serve both Python versions on the same Apache server - you will have to select a Python-version specific mod_wsgi package. For this reason, the virtual appliance has not yet been updated to Debian 10. For our production deployments, we serve up NAV and Graphite-web using a uWSGI application server, and use Apache + *mod_uwsgi* as a front to provide TLS and serving of static file resources. This works fine on Debian 10, as each uWSGI application instance is an independent process. I suspect I'll be working on updating the appliance based on our production deployment configs of uWSGI. Hopefully, we can hopefully provide some config examples soon, for those who are interested in building their own deployments (of course, if you are already deploying Graphite on a separate server, this is a non-issue for you).

New Install Issues
by Brian Mock 31 Jul '19

31 Jul '19

Hello, We are currently trying to set up a new installation of NAV (4.9.7). I have imported all of our devices and locations but am experiencing some issues. Some of our devices have interfaces that are showing wildly inaccurate data. It's mostly on any ten gig interfaces but also on a few gig interfaces but they're showing up to 15Tbps of traffic when in reality they're pushing far less than that and the graphs are very broken (see attached screenshots). Most ports on the same devices report properly so it's just a few isolated interfaces. The other issue we're running into is devices not showing linked to their neighbors. I tried working through the troubleshooting steps in the docs but the devices don't show up under unrecognized neighbors. On the devices however they show up in the ARP/CAM tables. We do have some links that don't support CDP but NAV should still be building these neighbor relationships through the ARP/CAM tables correct? Thanks for any assistance that you can provide! Regards, Brian Mock Unwired Broadband

Getting the ARP/Neighbors from Cisco ASA to NAV?
by Martin Burman 24 Jul '19

24 Jul '19

Hi We successfully use NAV for keeping track of devices but more often to find out which switchport a specific computer is attached to, either by searching for an IP address or a MAC address and it works great. We also have a lot of users directly attached to Cisco ASAs and these boxes does not give away their ARP/Neighbor cache via SNMP. The obvious first question is: has anyone successfully solved this already? Otherwise a "sh arp/sh ipv6 neigh" gives a parseable output and I assume this is the way to go via Expect or similar: Asa> sh ipv6 neighbor IPv6 Address Age Link-layer Addr State Interface fe80::6db1:8675:5895:8db1 423 001d.d8b7.1ce3 STALE ifname Is there a safe way to import this kind of data to NAV? Or any documentation hints that kicks me into the appropriate direction? I assume there are logic that updates existing mac addresses and creating new ones when needed and such and I don't want to ruin our installation. The second idea is to run some homebrewed snmp server that runs the "sh arp" in the back end and formats the output like a L3 switch would do, if that's the suggested way to go I would appreciate a decent oneliner with snmpwalk or similar that runs against a Cisco L3 switch (6500 or 6800) so I can compare the output I need to create. Thanks in advance and thanks a lot for a great piece of software! Martin Burman ---------- Göteborgs universitet IT-enheten +46 766-18 5982

NAV and Juniper virtual chassis
by Djuro Garvanovic 24 Jul '19

24 Jul '19

Hi I recently stumbled on your product while I was searching for a good network monitoring tool. So I started a POC with Debian package but got some problems with Graphite, and had to reverted to the appliance. Now that its running, I’m impressed over functions built in, especially the network auto mapping. But there is one thing I don’t know how to handle. We are mainly using Juniper EX4200, EX 3200 and EX2200 switches. Our Juniper EX4200 switches are set up as virtual chassis (stacked switches), and they all have the same ip address. The problem is that the switches, although they are in the same chassis, they are placed in different “rooms” a ring around our campus acting as distribution switches.

This will be useful when implementing NETCONF and/or RESTCONF, which is our current goal, but this can also be used to implement proper SNMPv3 support (since you will be able to store more than just community strings). I'm given to understand that the University of Linköping may be interested in developing support for SNMPv3, once management profiles hit the master branch. I'm also copying Pär Stolpe from LiU, so that he might comment (if he wants to) :-) -- mvh Morten Brekkevold Uninett

Announcement: NAV 4.9.4 released
by Morten Brekkevold 28 Mar '19

28 Mar '19

The fourth maintenance release of the 4.9 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 8/9 (Jessie/Stretch) are available in our APT repository [2] as usual. The Debian packages for NAV 4.9 have been rebuilt using dh-virtualenv, which means that most of the Python dependencies are now embedded into the packages themselves. If you have previously added a priority apt pin for packages from apt.uninett.no, you may now remove it, as there are no longer any other packages needed from that repository to run NAV. 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 is currently being updated at the time of this writing, and will be uploaded soon. Changes ======= NB: This release introduces a new dependency to py2-ipaddress==3.4.1 Fixed GitHub issues in this release: * #1639 (Not all NAV programs respect TIME_ZONE from nav.conf) * #1762 (navdump drops function-data) * #1788 (Deleting an alert profile subscription that has queued alerts will cause alertengine to process all those alerts as if they were new ones on the queue. ) * #1885 (LDAP authentication against Microsoft AD using suffix bind is broken in NAV 4.9) * #1894 (Terminals that don't support colors cause nav start/stop commands to crash) * #1895 (Verify nav.conf values as part of nav start) * #1896 (UnicodeEncodeError when LDAP user with non-ASCII characters in DN logs in) Please see the release notes [4] for more details.

FW: Unused port tracking / alert
by Daniel Gryzbon 25 Mar '19

25 Mar '19

Good day, We are now testing your product and we want to know, if is possible to track or be informed if some interface is not used for some time - e.q. no MAC address visible for long time or interface is down and not administrative down for long time. For example i try to configure alert profile with matchfield value.id cam.end_time with filter not equals 9999-12-31 23:59:59.999999 and added to filter group G01:All alerts with Add operation but no alert appeared on status tab. Is possible to somehow monitor it?

Fresh Install on Debian -> Graphite Unreachable
by Bothe, Mathias 20 Feb '19

20 Feb '19

Hello, i made a fresh nav installation on a fresh Debian 9 system. I installed the nav package by following the instructions here: https://nav.uninett.no/install-instructions/#debian After that I followed the instructions in /usr/share/doc/nav/README.Debian<https://raw.githubusercontent.com/Uninett/nav-debian/master/README.Debian> I skipped Part1, I did Part 2 to 6 as described. At point 4 Graphite, I followed https://nav.uninett.no/doc/latest/intro/install.html#integrating-graphite-w… I added the storage-*.conf files with symlink as described here: https://nav.uninett.no/doc/latest/howto/installing-graphite-on-debian.html Now I can Login into NAV, but Graphite is unreachable. So I have a few questions: Do i have to uncomment in file /etc/nav/graphite.conf? [carbon] # # NAV supports Carbon's UDP line receiver. Host and port information of # the backend can be configured in this section. # #host = 127.0.0.1 #port = 2003 [graphiteweb] # # Where is the Graphite web interface located. NAV needs this to get graphs # and data from Graphite. # #base=http://localhost:8000/ Do I have to create the graphite database and the apache webinterface by myself? As described here: https://nav.uninett.no/doc/latest/howto/installing-graphite-on-debian.html For me the installation instructions are not really clear and seem uncomplete. Can anyone help me? Cheers Mathias

Hello, When I use portadmin on a Dell N2048P, I change a port description for example and I clic on save. It say ok for change and ok for save very quickly. If I connect on the switch, the change is ok in the running-config, but when I check the startup-config, the change isn't done. I wait a few minutes and still no change. It is working well on Cisco 2960 and 3750 (despite sometimes it's slow if the stack is 8 switch) Can you help me find where is the problem ?

Get time out when accessing nav/ipdevinfo/{device}
by Jo Øiongen 05 Nov '18

05 Nov '18

Hi! Upgraded to latest and greatest a couple of days ago. After that everything works, except accessing devices. I have http://nav/ as my NAV URL root. Trying to access http://nav/ipdevinfo/{device} gives: Gateway Timeout The gateway did not receive a timely response from the upstream server or application. Can someone please point me in the right direction for where to start to look? I did a double upgrade. Debian and NAV. To get Debian up and running, including going from PostgreSQL 9.4 to PostgreSQL 9.6 I had to make some room on the hard drive. So I did a "cd /var/lib/graphite/whisper/nav/devices/" + "rm -rf *" Did I mess up here? BR, Jo

When I run the job form the command-line I get the following error: /usr/local/nav/bin/ipdevpolld -J inventory -n <boxname> 2018-09-25 08:37:19,646 [INFO nav.ipdevpoll] --- Starting ipdevpolld inventory --- 2018-09-25 08:37:26,439 [INFO plugins] Imported 30 plugin classes, 30 classes in plugin registry 2018-09-25 08:37:26,439 [INFO nav.ipdevpoll] Running single 'inventory' job for <boxname> 2018-09-25 08:37:26,497 [WARNING plugins.typeoid.typeoid] [inventory <boxname> ] Netbox has changed type from unknown to 1.3.6.1.4.1.42610.1.4.4 2018-09-25 08:37:26,561 [ERROR jobs.jobhandler] [inventory <boxname>] Plugin nav.ipdevpoll.plugins.modules.Modules(u'<boxname>') reported an unhandled failure Traceback (most recent call last): File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 423, in errback self._startRunCallbacks(fail) File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 490, in _startRunCallbacks self._runCallbacks() File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 577, in _runCallbacks current.result = callback(current.result, *args, **kw) File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 1155, in gotResult _inlineCallbacks(r, g, deferred) --- <exception caught here> --- File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 1097, in _inlineCallbacks result = result.throwExceptionIntoGenerator(g) File "/usr/local/lib/python2.7/site-packages/twisted/python/failure.py", line 389, in throwExceptionIntoGenerator return g.throw(self.type, self.value, self.tb) File "/usr/local/nav/lib/python/nav/ipdevpoll/plugins/modules.py", line 51, in handle need_to_collect = yield self._need_to_collect() File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 1097, in _inlineCallbacks result = result.throwExceptionIntoGenerator(g) File "/usr/local/lib/python2.7/site-packages/twisted/python/failure.py", line 389, in throwExceptionIntoGenerator return g.throw(self.type, self.value, self.tb) File "/usr/local/nav/lib/python/nav/ipdevpoll/plugins/modules.py", line 62, in _need_to_collect yield self.stampcheck.load() File "/usr/local/lib/python2.7/site-packages/twisted/internet/defer.py", line 1097, in _inlineCallbacks result = result.throwExceptionIntoGenerator(g) File "/usr/local/lib/python2.7/site-packages/twisted/python/failure.py", line 389, in throwExceptionIntoGenerator return g.throw(self.type, self.value, self.tb) File "/usr/local/nav/lib/python/nav/ipdevpoll/timestamps.py", line 108, in load self.loaded_times = yield db.run_in_thread(_unpickle) File "/usr/local/lib/python2.7/site-packages/twisted/python/threadpool.py", line 196, in _worker result = context.call(ctx, function, *args, **kwargs) File "/usr/local/lib/python2.7/site-packages/twisted/python/context.py", line 118, in callWithContext return self.currentContext().callWithContext(ctx, func, *args, **kw) File "/usr/local/lib/python2.7/site-packages/twisted/python/context.py", line 81, in callWithContext return func(*args,**kw) File "/usr/local/nav/lib/python/nav/ipdevpoll/db.py", line 100, in _reset return func(*args, **kwargs) File "/usr/local/nav/lib/python/nav/ipdevpoll/timestamps.py", line 100, in _unpickle key=INFO_KEY_NAME, variable=self.var_name) File "/usr/local/lib/python2.7/site-packages/django/db/models/manager.py", line 92, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "/usr/local/lib/python2.7/site-packages/django/db/models/query.py", line 361, in get num if num <= MAX_GET_RESULTS else 'more than %s' % MAX_GET_RESULTS nav.models.manage.MultipleObjectsReturned: get() returned more than one NetboxInfo -- it returned 2! 2018-09-25 08:37:26,561 [ERROR jobs.jobhandler] [inventory <boxname>] Job 'inventory' for <boxname> aborted: Job aborted due to plugin failure (cause=MultipleObjectsReturned('get() returned more than one NetboxInfo -- it returned 2!',)) OK, something is duplicated in my database, but where shall I look? --Ingeborg

Separating back-end processes
by William Daly - Network Specialist, VUSD Technology 13 Sep '18

Hello all, The metrics that were currently collect only keep increasing overtime. We would like to separate the various parts of NAV on to different servers to spread the resource burden. I have explored the idea of moving postgres and carbon to a different server. What would you recommend? Can I get away with just clustering Carbon? Thanks, William Daly Network Specialist Vacaville Unified School District (707) 453-6170
