Announcement: NAV 4.9.1 released
by Morten Brekkevold 07 Feb '19

07 Feb '19

The first 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 currently being updated at the time of this writing, and will be uploaded soon. Changes ======= Fixed GitHub issues in this release: * #1820 (ipdevpoll will not schedule jobs under NAV 4.9.0) * #1822 (Command line argument support for nav daemon startup config) * #1823 (Old switch port layout screen is blank in NAV 4.9.0) * #1824 (navdump crashes when dumping service table) * #1825 (Alertprofiles crashes when attempting to delete matchfield) * #1826 (Device history crashes when attempting to browse the history of an IP Device) * #1827 (Any l2trace search will crash with a Django FieldError) * #1828 (PDU dashboard widget crashes under NAV 4.9.0) * #1829 (Any toolbox descriptor file containing superfluous equal signs will be silently ignored by the web interface) * #1830 (MAC address prefix filters are horribly slow in arp and cam API endpoints) * #1831 (Threshold monitor crashes if rule returns Graphite error) Please see the release notes [4] for more details. Happy NAVing everyone!

Dell N2048P not saving
by Vinsonnaud Ludovic 07 Feb '19

07 Feb '19

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

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?

Goodbye, John-Magne!
by Morten Brekkevold 31 Aug '18

31 Aug '18

Today is John-Magne Bredal's last day at Uninett. I would like to take the time to acknowledge and thank John-Magne Bredal for the work he has put into NAV for the past 16 years, both at NTNU and at Uninett. He wrote his master's thesis on intrusion detection systems at NTNU under the guidance of Vidar Faltinsen, while at the same time working part-time on NAV development at the NTNU IT department. He graduated in 2002 and immediately started a full-time job at the NTNU IT department at the same time I did. Although he was working mainly with security at the time, he kept on with NAV development, focusing on NAV's Cricket integration and SNMP trap daemon, moving on to creating the Arnold detention system. While Uninett took charge of NAV development when I moved there in 2006, he kept on contributing from the NTNU side. He eventually moved on from the networking section to the software development section of the IT department, where he began honing his skills as a front end developer - skills he also put into practice in NAV development. In 2012, John-Magne was finally hired by Uninett to work full-time on NAV development. Since 2012, John-Magne has helped architect the redesigned NAV 4.0, introduced the NAV API and otherwise put much time and effort into improving the NAV user experience. Now, John-Magne is moving on to tackle the software needs of the Norwegian health sector, at Hemit, and I would like to wish him the best of luck! You will be missed :-) -- Morten Brekkevold Uninett

Navtopology Difficulties and VLAN Bandwidth load
by William Daly - Network Specialist, VUSD Technology 30 Mai '18

30 Mai '18

Hello all, A little background: I have been running NAV 4.7.1 for quite some time now. Every time I have tried to upgrade to 4.8.4, things get a little weird. Layer 2 topologies are miss-detected and certain sites show up as completely isolated from the rest of our WAN. Netmap does not show any layer 3 topology at all. Also the IPAM tool will not allow me to enter subnets as NAV has already detected previous prefixes. So, today I decided to do a clean install of 4.8.4. I input only two sites of devices. The issue I now have is netmap does not show layer 2 topology of the two sites. I only see layer 3 of the two sites. We use HP procurve layer 3 switches. I still do not see any bandwidth loads for any given VLAN's. Is this a known issue with NAV and HP procurves? I have never been able to see bandwidth loads on any VLANs from 4.7.1 to 4.8.4. Thank you! William Daly Network Specialist Vacaville Unified School District (707) 453-6170

netmap and lag
by Zhi-Wei Lu 09 Mai '18

Hi NAV gurus, We have a very limited test envioronment for NAV, our environment are Foundry based (->Brocade-> Arris and Extreme now). We have enabled lldp on edge switches, but not on ALL upstream routers. Even on connections with lldp on, the map does not show LAG ports correctly, it seems. Is there a manual way to fix netmap problem for those it fails to correctly identify the connections? Thank you.

Sizing the NAV server
by Zhi-Wei Lu 09 Mai '18

09 Mai '18

Hi NAV gurus, I have been testing NAV on and off for a while with a fraction of our devices on a small VM. I like it more and more as I am getting used to it. I would like to get recommendation of a NAV setup that can handle our environment. Our network is layered like the following: Border Router: 2 Core and Area Router: ~30 Building Router: ~100 Edge Switch: ~1500 Shall we use one big server or multiple servers, physical or virtual for various NAV management components? What CPU, MEMORY, DISK IO, and DISK size shall we plan for? Thank you very much for your help. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155

Interface graphs only showing in Graphite
by soren＠fab-it.dk 05 Mar '18

05 Mar '18

Hi list In my search for the missing link, I'm looking for a clue stick as to where my interface graphs disappear. I have installed Nav version 4.8.3 on Debian Stretch and currently monitoring two HP switches, ProCurve 2810 and 2910. The problem I have is in the "ranked statistics"-page, there is no interface traffic data in the graphs - instead I get a message: "No data was found for the given timeframe. This may indicate a problem with the data collection and/or presentation. Try choosing a longer timeframe to see when the problem started." But I do get graphs if I choose the "CPU highest average" - so SNMP apparently is working fine. When I access Graphite directly on port 8000 and traverse the tree Metrics-> nav-> devices-> ip-> port-> ifinOctets I am able to see a graph for that interface. What link between Nav and Graphite am I missing? Curiously I tried the shrink wrapped image on a VirtualBox and had the opposite problem. Monitoring another Procurve 2910 I only got traffic graphs and no "CPU highest average"-graphs. Kind regards Søren Aurehøj - Fab:IT
