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

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

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

by Morten Brekkevold 21 Jun '18

21 Jun '18

The fifth maintenance release of the 4.8 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 published in our APT repository [2], as usual. The virtual appliance will be updated shortly. Changes ======= Fixed GitHub issues in this release: * #1688 (Report crashes when using %, * or non-ASCII characters in filter values) * #1693 (Changing password from "User and API Administration" leads to KeyError) * #1702 (Adding log entries with non-ascii characters crashes page) * #1711 (Regression: Report crashes when attempting to sort a column filtered on a non-ASCII value) * #1719 ('navdump -a' puts status messages into the output files) * #1721 (Widget spinner visible when opening tool-menu) * #1729 (Room search "CSV download" CR in "last active" field) * #1734 (l2trace crashes when searching for invalid IP addresses) * #1735 (HTTP errors from Graphite shouldn't crash NAV's Graphite render proxy) Copyright changes: Third party copyright owners of NAV code, like The Norwegian University of Science and Technology, and the University of Tromsø, have signed over their copyright for their code contributions to Uninett. NAV 4.8 is still licensed under GPLv2-only, but will be relicensed under GPLv3 in the upcoming 4.9 series. This should have no impact on end users; as a company with public ownership, Uninett will always strive to keep NAV under a free and open source license. Happy NAVing everyone!

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

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
