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!

NAV 3.5.6 is now available for download at Launchpad: https://launchpad.net/nav/3.5/3.5.6 This release fixes 6 bugs in NAV 3.5. Most importantly, it fixes a bug that caused inconsistency in ARP data under certain circumstances. This would cause problems with proper Machine Tracker operation. See https://bugs.launchpad.net/nav/+bug/538001 for details. The log of all changes to the 3.5 series is attached to this message. A binary package for Debian 4 and 5 (Etch and 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

New version of the Debian package
by Morten Werner Forsbring 22 Mar '10

22 Mar '10

Hi. Last week I updated the Debian package living on Alioth [1]. The changelog is as follows: [ Morten Brekkevold ] * Verify that pid files exist before HUPing in logrotate config. [ Morten Werner Forsbring ] * Adjusted init-script to not fail if 'nav stop' fails (happens sometime during configure). Thanks to Morten Brekkevold for reporting this. * Increase some debconfig priorities (those regarding automatic database stuff). * Updated README.Debian (the PostgreSQL-section was outdated). Thanks to Vidar Stokkenes and Morten Brekkevold for comments. FYI. - Werner

Patching forgetSQL on Python 2.5/2.6
by Morten Brekkevold 22 Mar '10

22 Mar '10

Hi all, forgetSQL is an unmaintained piece of shi^H^Hoftware that NAV versions up to 3.5 depend on. While we have removed this dependency from the coming NAV 3.6, some will experience warnings when running NAV under Python 2.5, and outright failures on Python 2.6, due to problems with the forgetSQL module. The forgetSQL module raises string exceptions in three places, and these are deprecated in Python 2.5, and not supported in 2.6. You may see error messages such as these: /var/lib/python-support/python2.5/forgetSQL.py:212: DeprecationWarning: raising a string exception is deprecated raise "NotFound" or File "/var/lib/python-support/python2.6/forgetSQL.py", line 212, in __new__ raise "NotFound" TypeError: exceptions must be classes or instances, not str I'm attaching a quick forgetSQL patch I've written to overcome these problems until NAV 3.6 has reached a stable release. -- Morten Brekkevold UNINETT
