SQL errors in NAV 3.4
by Morten Brekkevold 21 Jul '08

21 Jul '08

Hello everyone, While testing Werner's upcoming Debian package of NAV 3.4.1, we discovered some bugs in the SQL scripts that initialize the NAV database, see [1] for details. Two of the problems described in [1] will affect anyone who has initialized a new NAV database while installing NAV 3.4.0 or 3.4.1 from scratch. These two problems are potentially serious if you value the correctness of your machine tracker data. Whenever your delete an IP Device from NAV, there are two database rules making sure that every machine tracker entry related to this IP Device is closed. If you are affected, these rules will not have been defined, and all open records related to an IP Device will stay open as the device is deleted. The third problem is relatively minor. It only affects those who have initialized the NAV database on PostgreSQL 8.3 or newer. When a service check is deleted, a database rule removes NAV's knowledge of the service response time RRD file. Other parts of NAV will automatically remove this when it sees the file has gone 30 days without being updated. To summarize: If you upgraded to NAV 3.4 from an older version, and you do not run PostgreSQL 8.3 or newer, you do not need to take any action. If you are affected by the above problems, you can either wait for NAV 3.4.2, which we hope to release shortly, or you can apply the attached, short SQL script in your NAV manage database (using psql). [1] http://sourceforge.net/support/tracker.php?aid=2023345 -- mvh Morten Brekkevold UNINETT /* * * This SQL script is designed to upgrade your NAV database from * version 3.4.0 or 3.4.1 to 3.4.2. * * This script is only necessary if either: * * 1.

NAV and HP ProCurve Switches
by Stokkenes Vidar 25 Jun '08

25 Jun '08

Hello, This might be a stupid question, but can someone with HP ProCurve equipment please guide me through the progress of getting them to work with NAV? I've added the device (HP Procurve 2824) in the database, but NAV doesn't seem to be pulling port info from the switch. The switchview shows it's been polled, but there is no "portview" on the polled switch. Any ideas? Any input is appreciated. ------------------------------------------------------ Vidar Stokkenes Konsulent Nettverk Seksjon for nettverk og telekom HN IKT - Tromsø Tlf: 76 16 61 87 / 77 66 99 55 Mobil: 95 87 99 42 e-post: vidar.stokkenes(a)hn-ikt.no<mailto:vidar.stokkenes@hn-ikt.no> [cid:image001.png@01C8D6C3.7182BF60]

Well, upon reading the truss output of "nav start getDeviceData", it seems that the "su" command is the one that hangs after the chdir command. Can you successfully execute "su - navcron" as root? Does the navcron user have a valid login shell? > What is the difference between 'nav start ....' and executing the process > directly, ie: > cd etc/init.d > ./getDeviceData start > > "nav start ..." fails and "./getDeviceData start" succeeds? I think the > inherent difference may help us to understand what is happening and why the > failure. Or at least may help me to locate more pertinent data. There's no difference, really. The nav command is a convenience tool to do all the starting and stopping in one go (plus the added crontab manipulation). It still calls the etc/init.d scripts in the end. Are you running both commands as root? >> Besides, you say that "nav start alertengine" seems to stall, and this >> command will not modify the crontab, since alertengine isn't a cronjob >> but a daemon.

I su'd to navcron, just to verify and this > command is denied (as I expected). Wait, are you saying that "su - navcron" fails? That would be a reasonable cause for your problem. Several of the init scripts are designed to be run as root, and use su to drop privileges to navcron before executing processes that cannot drop privileges by themselves (such as java). As I mentioned in less detail above, the navcron user must have a valid login shell for the su'ing to work. > there is a Python class for crontab but nothing that defines command line > arguments (not familiar with python). Crontab commands are hardcoded on lines 243 and 261 in startstop.py. The nav script requires root access to run properly (and will give a warning/error if executed by anyone but root). > I've also included the strace output - as it sounded like you are more > familiar with strace - may help to locate the issue.

Good Evenin', Being new to nav..... Installation is on FreeBSD v6.x. Performed initial install from the 'ports' collection. After following instructions on basic configuration (included setup of Postgres, setting up a couple devices, room, location, etc.) it appears that some services still aren't starting: $$> nav start Starting: cricket iptrace logengine mactrace maintengine networkDiscovery pping smsd thresholdMon Failed: alertengine eventengine getDeviceData servicemon I've already done some research and had to hand-tool some .py files as there were errors for "import sre as re" and python stated that it was deprecated, ie: it should be "import re" (sre is now re) I'm not seeing any log data (even with debug=6 in nav.conf) for the failed services. Does anyone have information that may lead to this being more successful? BTW - we utilize Apache 2.x with AD authentication for internal resources. I've seen some errors with python and the web pages as well - is there an expectation that it would be Apache 1.x instead? Here are some specifics: OS: FreeBSD v6.x (Microsoft/BSD shop) Java: Diablo JDK-1.5.0 Tomcat: 6.0.14 Cricket: 1.0.5_4 nav: 3.2.2 Python: 2.5.2 Apache 2.2.8 ant: 1.7.0 Thanks!

The switch's ARP cache will only contain entries for addresses that are communicating directly with the switch on layer 3 (i.e. your workstation telnetting to the switch CLI).

Correct :-) -- mvh Morten Brekkevold UNINETT P.S. I'm assuming you accidentally forgot to reply-to-all, so I'm Cc'ing the nav-users list.

Problem with NAV 3.3.3 Machine Tracker
by Helder Vieira Mendes 17 Apr '08

17 Apr '08

Hello, Helder Mendes from ISEP. I am using NAV 3.3.3 in Debian 4.0, but the Machine Tracker is not working well because if I do MAC Search NAV return´s the IP in the correct door / switch (by ARP table search), but if I search by IP does not return the MAC, does not return any thing ... The ARP tables are the same it should work ... Thanks for helpping. Helder Mendes, ISEP / IPP

Migration from Subversion to Mercurial
by Morten Brekkevold 09 Apr '08

09 Apr '08

Hello everyone, Those of you who subscribe to the nav-dev list will already know that last week we migrated from Subversion to Mercurial as our version control software. Each official development branch now has its own repository at http://metanav.uninett.no/hg/ . The development branch named "default" represents what we called trunk in Subversion. If you have been using Subversion to get the latest development version, you should now use Mercurial, and clone the repository at http://metanav.uninett.no/hg/default/ . For more information about Mercurial, please see http://www.selenic.com/mercurial/ . Those of you who monitor NAV commit logs by subscribing to the nav-commit mailing list should now subscribe to the individual RSS or Atom feeds of the branch repositories at http://metanav.uninett.no/hg/ - the nav-commit mailing list will soon be taken offline. Have a great day! -- mvh Morten Brekkevold UNINETT

Announcement: NAV 3.3.3 released
by Morten Brekkevold 28 Mar '08

28 Mar '08

NAV 3.3.3 is now available for download at SourceForge, see http://sourceforge.net/projects/nav :-) This is a bugfix release, the list of bugs fixed can be found in the attached changelog. The bugfixes require manual intervention, as there are two database trigger fixes, and a need to edit Cricket config. I've attached the relevant parts of the release notes to this announcement. If upgrading from other versions than 3.3.2, please refer to the complete release notes on Sourceforge or in the tarball. Binary packages for Debian will be available soon. The Debian package is maintained by Morten Werner Forsbring, on commission from UNINETT. -- mvh Morten Brekkevold UNINETT Upgrading from NAV 3.3.2 and earlier ==================================== NAV 3.3.2 and earlier had some serious bugs in database triggers, which would munge historic CAM and ARP data when IP devices or prefixes were deleted. To fix these bugs on upgrading to this version, you *must* remember to run the SQL script doc/sql/upgrade/3.3.0.sql (unless an automated package installer already did this for you). See doc/sql/README for more info on running SQL scripts. A bug in makecricketconfig would cause 32-bit traffic counters to be used for some non-Cisco devices, such as Juniper routers and switches. This would lead to serious errors in traffic graphs for interfaces with traffic over 500Mbit/s on these devices. The fixed makecricketconfig in NAV 3.3.3 also requires you to add the following three lines to the Defaults file in your top-level cricket configuration directory: targetType subv2-interface ds = "ifHCInOctets, ifHCOutOctets" view = "Octets: ifHCInOctets ifHCOutOctets" Upgrading from NAV 3.3.2 and earlier ==================================== NAV 3.3.2 and earlier had some serious bugs in database triggers, which would munge historic CAM and ARP data when IP devices or prefixes were deleted.

While I've never seen this one before, a quick Google search turned up this: http://www.dscpl.com.au/wiki/ModPython/Articles/IssuesWithSessionObjects Apparently, the module import mechanism has been changed in newer versions of mod_python (such as 3.3, which is present on Ubuntu 7.10). The way in which the status page stores each user's status page preferences will evidently no longer work under mod_python, and that's why you're seeing this error :-( Our dev server still has mod_python 3.2, and we've not seen this issue there, so it apparently occurs only on mod_python 3.3 and newer. Unfortunately, I have no certain quick fix for you. I will have to figure out whether this can be worked around, or whether we need to rewrite the way in which the Status page stores preferences. I'll see if I can get my hands on mod_python 3.3 to reproduce the error. You may however be able to workaround this issue if you can downgrade your mod_python version to 3.2. It is likely that the mod_python package from Ubuntu 7.04 (feisty) is still compatible with 7.10 (gutsy) and can be installed. If you are able to do this, you may also need to purge the stored status preferences from the NAV database. That can be accomplished by running 'psql navprofiles nav', using the database password from /usr/local/nav/etc/db.conf, and then running the following SQL statement: DELETE FROM accountproperty WHERE property='statusprefs'; -- mvh Morten Brekkevold UNINETT

PythonHandler common error SLES 10
by johan.ponten＠ericsson.com 26 Mar '08

Hi, I have NAV 3.2.2 installed on SLES 10. After quite some work I'm now at a point where I have two major issues (two posts) and I'm a bit stuck. 2. Logging in to the WEB interface and many other operations result in the following type of error output in Firefox. This particular one when selecting "Edit database" in the Tools. I have already recompiled a lot of python files, but for the Template.py on the last row I cannot find a source template to compile. Am I on the right track at all?

Layer 2 Mapping
by yonat2＠post.tau.ac.il 26 Mar '08

26 Mar '08

Hello, I've been trying to setup nav to map layer2 in my network, (see where each port in the switches leads), only one of the switches displays where each of its port leads. all the other switches in the network have either one of these problems: 1. show an empty port view. 2. show the port view, but when clicking on either port - there is no information of to which netbox it leads. perhaps nav is missing crucial mibs information, and cannot find the right oid branches? I would greatly appreciate any feedback on how to fix the port views, Thanks, Yonatan.
