Announcement: NAV 3.6.0b2 released
by Morten Brekkevold 10 Jun '10

10 Jun '10

The second beta test release of NAV 3.6 is now available for download at Launchpad, NAV 3.6.0b2: https://launchpad.net/nav/3.6/3.6.0b2 Beta testing is open to anyone, but please be aware, this code IS NOT production ready. If you wish to test the beta code, do so on a dedicated test system. Three of our own customers, in addition to our self, will be running "official" beta tests, so we have a good spread in the types of networks and devices we get to test the new code on. The most important fix in this beta is likely the migration of switch port statistics collected by Cricket. Upgrading an existing NAV installation to 3.6.0b1 would lose that data (not the data itself, just NAV's link to it). A binary package for Debian 5 (Lenny) will be made available as soon as possible. The Debian package is maintained by Morten Werner Forsbring, on commission From UNINETT. Happy NAVing everyone! -- Morten Brekkevold UNINETT

Interfaces missing from Cricket/NAV configuration
by Sigurd Mytting 09 Jun '10

09 Jun '10

Hi! I'm missing some interfaces and descriptions in my cricket-configuration on specific Cisco-models, on all my WS-C2960-48TC-L (48port 10/100 and 2x dual-purpose 1Gbit) the two first ports in the cricket configuration are given interface-index of the Gi's and the index for the two first Fa's are missing in the configuration. this is an example: target "1_1" order = 48 interface-index = 10101 short-desc = "Cisco 2960 48ports switch, 22A, 22A-skap, Forskjellige patcheskap" target "1_2" order = 47 interface-index = 10102 short-desc = "Cisco 2960 48ports switch, 22A, 22A-skap, Forskjellige patcheskap" target "1_3" order = 46 interface-index = 10003 short-desc = "Cisco 2960 48ports switch, 22A, 22A-skap, Forskjellige patcheskap" If I go to "IP device info" in NAV the ports Fa0/1 and Fa0/2 are missing from the figure at the bottom. On all my 2960, 3560 and 3750 interface descriptions are missing, but it's ok on 2940 and 4500. To me it looks like something wrong with NAVs data collection, but I have no idea where to start looking... This installation is a few months old, all running the latest and greatest Debian and NAV-package: $ cat /etc/debian_version 5.0.4 $ dpkg -l | grep nav ii nav 2+3.5.6-1lenny1 Network Administration Visualized Any help is appreciated! Cheers, -Sigurd

diagnostics? mac-address dump per equipment
by João Pagaime 23 Apr '10

23 Apr '10

Hello nav-users I'm just starting to use NAV. After browsing a little throug the documentation I have a few questions that maybe some ou you guys can answer: - NAV looks a complex system with lot of automation going on behind the scenes. How do I find out if all this automation (started fron CRON I assume) is running well? Is there some error log somewhere? - How do I list the forwarding database of an ethernet switch? thanks João Pagaime

Strange names on switchports
by Lars Kulseng 21 Apr '10

21 Apr '10

Hi I'm using NAV 3.5.4, and I'm getting some strange names on my switchports, in the statistics section. I have a couple of stacked Cisco 3750 switches. NAV is showing ports named: <IP>/1_488 and <IP>/1_496 How can I find the real names of these ports, and why are they named this way? Lars Kulseng

ipdevinfo takes ages to load
by Stokkenes Vidar 21 Apr '10

21 Apr '10

Hello everyone, For a very long time, I've had problems with slow loading ipdevinfo pages (typically when opening a switch listed in "Reports" -> All IP Devices) I first thought this was related with poor performance I/O on my VMWare instance the server was running on, but the problem persists on a physical server as well. Sometimes it never opens, it just "hangs" in a state of loading the page. I haven't tried to Wireshark the connection between my client and the NAV server itself, nor between the NAV server and the postgres server (which is hosted on another server on the same subnet) I don't have the same problem on all switches, and I've also thought I might have been unlucky catching my server in a heavy cricket/collection cycle (although its running on a 2 x QuadCore and 16GB memory system.....) I've tried to look in the error- and access logs in /var/log/apache2 without seeing anything suspicious. The load of the server is also quite low when I have this problem, so I doubt it's a performance issue. Have anyone else had a similar problem, or knows how I can troubleshoot it? Currently running NAV 3.5.6 on a Debian Lenny system with an external postgres database (running in RH EL5) Many thanks for any help! ------------------------------------------------------ Vidar Stokkenes Konsulent Nettverk Seksjon for nettverk og telekom Helse Nord IKT - Tromsø Tlf: 76 16 61 87 / 77 66 99 55 Mobil: 95 87 99 42 e-post: vidarst(a)hn-ikt.no

missing availability, response time
by lars.kulseng＠item.ntnu.no 21 Apr '10

21 Apr '10

Hi I am monitoring wireless access points using NAV 3.5.4. Some of these access points only report "N/A" for Availability and response time. This is a similar issue to bug #345783 submitted by Yours truly, but not identical, because here there is no data at all, while bug #345783 addressed an issue with certain time periods being empty. It may be related though... I have looked in the rrd_file table, and there are entries for the relevant devices, as well as rrd files in the rrd folder. Is this a bug or a seeding error? Thank you! Lars
