Setting up NAV from scratch/non-OVA (Graphite-issues)
by Joachim Tingvold 27 Apr '14

27 Apr '14

Hi, Decided to install NAV from 'scratch' (i.e. not use the OVA-package). Got NAV running fine, but had some hiccups getting Graphite working as it should. Found no documentation on this what-so-ever (neither on the NAV-pages, or the Graphite-pages), so had to try-and-fail some. Thought I'd share. - Debian Wheezy (not OVA) - NAV via apt (from https://nav.uninett.no/debian) root@tardis:~# dpkg -s nav|grep Vers Version: 4.0.1-3 1) Fixed /etc/nav/graphite.conf; base=http://localhost:8888/ 2) Copied content of '/usr/share/graphite-web/apache2-graphite.conf' into own VHost; <VirtualHost localhost:8888> ( + add NameVirtualHost + Listen in /etc/apache2/ports.conf) 3) Set 'CARBON_CACHE_ENABLED=true' in '/etc/default/graphite-carbon' Set 'ENABLE_UDP_LISTENER = True' in '/etc/carbon/carbon.conf' Set 'SECRET_KEY = <longsecretstring>' in '/etc/graphite/local_settings.py' Set 'TIME_ZONE = '<Gallifrey>' in '/etc/graphite/local_settings.py' 4) cd /usr/share/pyshared/graphite python manage.py syncdb 5) Started carbon-cache (/etc/init.d/carbon-cache start) 6) Started NAV + apache Should work. Some of the errors I got along the road; <http://files.jocke.no/b/nav-graphite-error.txt>. -- Joachim

Is there a way to change the default 10 rows in the lists?
by davide＠wpweb.com 23 Apr '14

23 Apr '14

It should be useful if I can change the default 10 rows in the "Show xx entries" in the lists. I searched through the configuration file and in the .js but I can't change this. I wish to put 50 rows or at least "all". Thank you

Problem with uplink detecion
by Martin.Jaburek＠cah.cz 22 Apr '14

22 Apr '14

Hi, I just face another problém with uplink detection. I tried to follow documentation about troubleshooting topology, but it yielded no results. I check switchport report of both connected devices and there it is showed in the columnt labeled as connected to. I also check cdp and it also report it correctly. I also found another problém when it displays an actual uplink, but with empty from device (which seems to me quite strange). In other case an uplink is showed only on one device but not the other. Is there any limit about number of uplinks? (I have more then ten uplinks on one box) Brgds Mat -----Original Message----- From: nav-users-request(a)uninett.no [mailto:nav-users-request@uninett.no] On Behalf Of Morten Brekkevold Sent: Thursday, March 27, 2014 3:09 PM To: nav-users(a)uninett.no Subject: Announcement: NAV 3.15.7 released For those of you who wish to continue running NAV 3.15 for while, the seventh maintenance release of this series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.7 This release fixes 12 reported issues: * LP#1251211 (portadmin wishlist: option to reset active interface whene changing vlan) * LP#1285601 (Switch ports on non-existant VLANs on Cisco switches don't appear as switch ports in NAV) * LP#1287700 (SeedDB will readily accept serial numbers with trailing spaces) * LP#1289219 (affected displays no information on nodes not in topology) * LP#1289320 (Submitting invalid alert subscription forms cause crash instead of error message) * LP#1291956 (LDAP auth against MS AD broken since NAV 3.14.1592653) * LP#1291978 (User supplied login name is not escaped in LDAP search filters, causing possible injection vulnerabilities) * LP#1292513 (sysname/reverse dns lookups are inconsistent or lacking after a bulk import) * LP#1293621 (missing cascade in table accounttool) * LP#1295092 (Only modules and power supplies on first member are collected from stacked HP 2920) * LP#1297200 (powersupplywatch crashes when there are more than ~1024 devices to poll) * LP#1297767 (Django exposes sensitive data like: username/password) Please report further bugs at https://launchpad.net/nav/+filebug A binary package for Debian Wheezy has been made available in our APT repository, as usual.

Problem retrieving port statistics
by Martin.Jaburek＠cah.cz 10 Apr '14

10 Apr '14

Hi, After recreating whisper databases I can see some of the graphs. Now I have another problém - not all statistics are collected! I checked graphite and it displays only few of them. The nav systém have ran for a day now, so I would expect, that it is enough time to collect all informations. In the screenshot (made from graphite webinterface) you can see various collected statistics - they are not even the same for various ports. There are no problems reported for this device in the ipdevpoll.log Any ideas?

We think this may be related to this bug: https://bugs.launchpad.net/nav/+bug/1292513 . This has been fixed and will be part of the next release.

Graphite on other machine
by Martin.Jaburek＠cah.cz 07 Apr '14

Hello, I tried to run graphite on another machine. I was able to redirect statistics collection, but I cannot see graph data: I have made changes in etc/graphite.conf: [carbon] # # NAV supports Carbon's UDP line receiver. Host and port information of # the backend can be configured in this section. # host = IP port = 2003 [graphiteweb] # # Where is the Graphite web interface located. NAV needs this to get graphs # and data from Graphite. # base=https://IP When I first started NAV, it was configured to use the graphite on the same machine as NAV. It worked. When I changed it and restarted NAV processes it sent statistics to the new IP (I confirmed it via graphite web fronted), but it still tries to access old graphiteweb for rendering graphs, not the one changed in grahpite.conf. Can there be a problém with certificate? (it is self signed one) Isn't it somehow cached in a database?

But I am still experiencing gaps on some graphs. There is one device which suffers from it most - see attached graphs.

Systém metrics are just fine on this device. I checked the 5min graph of ipdevpoll systém metrics and it shows 100 at peak times, what I assume are only nearly 2 minutes. I'm monitoring about 140 devices right now with nav. I think that it is much correlated to my yesterday upgrade to 4.0.0 (from 4.0b5). Since then I can also see attached errors.

Which graphs have gaps? Port metrics? System metrics? All of them? How many devices are you monitoring, and what does the runtime of the various ipdevpoll jobs look like? If the 1minstats job is spending more than 1 minute to complete for any device, there may be gaps its graphs, 5 minutes for the 5minstats job. -- Morten Brekkevold UNINETT

NAV authentication with LDAP + MS AD
by Sjøholt Steinar Otto 04 Apr '14

04 Apr '14

Hi We are running NAV with LDAP-authentication against MS ActiveDirectory. This were working fine for a while, but then the issue with case sensitive usernames appeared (Bug#1207722) The fix seems to have broken LDAP authentication with AD completely. As we are a small group of nav-users here, it took a while (and a passwordchange) to discover this. What happens now is that authentication works (for existing users) as long as the user doesn't change his password. Any new passwords will not work (as the LDAP-query against AD keeps failing), BUT the old (cached?) password still works(!) I don't know if this is by design... But it seems a little flawed to me. Since the addition of ":caseExactMatch:" doesn't work with AD, a better solution to Bug#1207722 would be to have NAV check the output of the LDAP-query to get the actual username (with correct casing) and use this to create the user in the database instead of the actual userinput.

Because of some critical bug fixes from the 3.15 series, we have also released version 4.0.1, the first maintenance release of the 4.0 series, today. The source code is available for download at Launchpad [1] and a new package for Debian Wheezy has been published in our APT repository [2]. Changes ======= The following reporte bugs have been fixed in the 3.15 series and are part of 4.0.1: * LP#1300117 (Fix for bug 1295092 causes ipdevpoll inventory jobs to crash for Cisco devices) * LP#1301251 (LDAP users with non-ASCII characters in their name cause login page to crash when user lookup method is 'search' (MS AD)) * LP#1301343 (CDP cache is never refreshed on devices that do not respond to CDP-MIB::cdpGlobalLastChange) * LP#1301349 (Module down alerts fail to mention the module's name) * LP#1301794 (LDAP group membership verification crashes with UnicodeDecodeError when username contains non-ASCII chars) A single issue affecting only the 4.0 series was fixed: * LP#1301260 (seeddb prefix edit does not display all fields) Because the 3.15 and 4.0 series are maintained in parallel, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades.

Announcement: NAV 4.0.0 released
by Morten Brekkevold 27 Mar '14

27 Mar '14

We are proud to present the final NAV 4.0.0 release, now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0.0 Changes ======= As announced when we released the first beta version, NAV 4.0 introduces two major changes. The two big changes are: 1. The complete replacement of Cricket as a 3rd party tool for statistics collection and graphing. NAV 4 collects the statistics using the already existing ipdevpoll SNMP collector, and uses Graphite as a 3rd party service for storing and graphing this data. This also means NAV no longer uses RRDtool for storing time-series data. 2. A full design overhaul of the web interface, using the Foundation CSS framework. The full release notes for this release can be read at [1]. You are also advised to read the updated installation docs at [2]. If you are upgrading from an existing 3.15 installation, you should avoid starting the new NAV version before migrating your old Cricket/RRD-based statistics to Graphite/Whisper. Instructions for this can found at [3]. If you want to upgrade from a 4.0 beta version, be advised that the polling interval for sensor statistics has been changed from 5 minutes to 1 minute. The updated example storage-schemas.conf reflects this. The whisper files under nav/devices/*/sensors/*.wsp must either be resized to include a new 1 minute resolution archive, or be deleted so that Carbon will re-create empty files from the new config. Debian packages =============== Debian packages have been uploaded to our repository, instructions for using the repository are still found at [4]. NAV's documentation does not cover installation of Graphite's Carbon daemon and the Graphite web interface, which are necessary dependencies in NAV 4.0; it only mentions configuration measures. We have backported a graphite-web package, as it is not provided by the Debian Wheezy distribution. This package does not automatically set up a Graphite web instance for you. We will write a guide suggesting how to do so, but it will be largely based on the shell script we use to automatically build our published virtual appliance. This shell script can be viewed at [5] (ca. lines 35-80). NAV 3.15 support ================ We will continue to support the 3.15 series at least until NAV 4.1 is released, but we recommend all new users to start with NAV 4. Happy NAVing everyone!

Nav Django exposing Username/Password in error case
by Mischa Diehm 26 Mar '14

26 Mar '14

Hi, I was playing around with ldap/AD integration and got this errorreport mailed to our NOC-Group (see below) - this mail leaks my username/password in cleartext. I think this should really be avoided for any case happening! I don't have a clue about django but a quick search showed me this: https://docs.djangoproject.com/en/dev/howto/error-reporting/ Especially interesting might be this part: ... Filtering sensitive information <https://docs.djangoproject.com/en/dev/howto/error-reporting/#filtering-sens itive-information> Error reports are really helpful for debugging errors, so it is generally useful to record as much relevant information about those errors as possible. For example, by default Django records the full traceback <http://en.wikipedia.org/wiki/Stack_trace> for the exception raised, each traceback frame <http://en.wikipedia.org/wiki/Stack_frame> ¹s local variables, and the HttpRequest <https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.Htt pRequest> ¹s attributes <https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-att ributes> . However, sometimes certain types of information may be too sensitive and thus may not be appropriate to be kept track of, for example a user¹s password or credit card number. So Django offers a set of function decorators to help you control which information should be filtered out of error reports in a production environment (that is, where DEBUG <https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DEBUG> is set to False): sensitive_variables() <https://docs.djangoproject.com/en/dev/howto/error-reporting/#django.views.d ecorators.debug.sensitive_variables> and sensitive_post_parameters() <https://docs.djangoproject.com/en/dev/howto/error-reporting/#django.views.d ecorators.debug.sensitive_post_parameters> . ... I wonder if than can be integrated for NAV or if there is another way to get around exposure like that? Mischa Original mail we became for django error: ---- Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/usr/lib/pymodules/python2.7/nav/web/webfront/views.py", line 89, in login return do_login(request) File "/usr/lib/pymodules/python2.7/nav/web/webfront/views.py", line 122, in do_login account = auth.authenticate(username, password) File "/usr/lib/pymodules/python2.7/nav/web/auth.py", line 95, in authenticate auth = ldapauth.authenticate(username, password) File "/usr/lib/pymodules/python2.7/nav/web/ldapauth.py", line 120, in authenticate lconn = open_ldap() File "/usr/lib/pymodules/python2.7/nav/web/ldapauth.py", line 76, in open_ldap server = _config.get('ldap', 'server') File "/usr/lib/python2.7/ConfigParser.py", line 618, in get raise NoOptionError(option, section) NoOptionError: No option 'server' in section: 'ldap' <WSGIRequest path:/index/login/, GET:<QueryDict: {}>, POST:<QueryDict: {u'origin': [u''], u'username': [u'diehm-adm'], u'password': [u'godDamnitDjango']}>, COOKIES:{'sessionid': 'd660941ae6b821799dbb47ed41d47009'}, META:{'CONTENT_LENGTH': '52', 'CONTENT_TYPE': 'application/x-www-form-urlencoded', 'DOCUMENT_ROOT': '/usr/share/nav/htdocs', 'GATEWAY_INTERFACE': 'CGI/1.1', 'HTTPS': '1', 'HTTP_ACCEPT': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'HTTP_ACCEPT_ENCODING': 'gzip, deflate', 'HTTP_ACCEPT_LANGUAGE': 'de,en-us;q=0.7,en;q=0.3', 'HTTP_CONNECTION': 'keep-alive', 'HTTP_COOKIE': 'sessionid=d660941ae6b821799dbb47ed41d47009', 'HTTP_DNT': '1', 'HTTP_HOST': 'urz-nav-pet.urz.unibas.ch', 'HTTP_REFERER': 'https://urz-nav-pet.urz.unibas.ch/index/login/', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0', 'PATH_INFO': u'/index/login/', 'PATH_TRANSLATED': '/usr/share/pyshared/nav/wsgi.py/index/login/', 'QUERY_STRING': '', 'REMOTE_ADDR': '131.152.2.16', 'REMOTE_PORT': '59503', 'REQUEST_METHOD': 'POST', 'REQUEST_URI': '/index/login/', 'SCRIPT_FILENAME': '/usr/share/pyshared/nav/wsgi.py', 'SCRIPT_NAME': u'', 'SERVER_ADDR': '131.152.2.216', 'SERVER_ADMIN': 'webmaster@localhost', 'SERVER_NAME': 'urz-nav-pet.urz.unibas.ch', 'SERVER_PORT': '443', 'SERVER_PROTOCOL': 'HTTP/1.1', 'SERVER_SIGNATURE': '<address>Apache/2.2.22 (Debian) Server at urz-nav-pet.urz.unibas.ch Port 443</address>\n', 'SERVER_SOFTWARE': 'Apache/2.2.22 (Debian)', 'SSL_TLS_SNI': 'urz-nav-pet.urz.unibas.ch', 'mod_wsgi.application_group': 'urz-nav-pet.urz.unibas.ch|', 'mod_wsgi.callable_object': 'application', 'mod_wsgi.handler_script': '', 'mod_wsgi.input_chunked': '0', 'mod_wsgi.listener_host': '', 'mod_wsgi.listener_port': '443', 'mod_wsgi.process_group': 'NAV', 'mod_wsgi.request_handler': 'wsgi-script', 'mod_wsgi.script_reloading': '1', 'mod_wsgi.version': (3, 3), 'wsgi.errors': <mod_wsgi.Log object at 0x7fa322859430>, 'wsgi.file_wrapper': <built-in method file_wrapper of mod_wsgi.Adapter object at 0x7fa3228655d0>, 'wsgi.input': <mod_wsgi.Input object at 0x7fa3210d6eb0>, 'wsgi.multiprocess': True, 'wsgi.multithread': True, 'wsgi.run_once': False, 'wsgi.url_scheme': 'https', 'wsgi.version': (1, 1)}> -- Mischa Diehm | Network Operations Center (NOC) UniBasel | UniRechenZentrum (URZ) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | http://urz.unibas.ch

Migration to new NAV version

Hi, we migrated our installation to a new HW and Debian stable (3.14.15-1 -> 3.15.5-1). I got all dump.py data migrated without problems. Now we got a lot of User Accounts and Groups with a lot of different Privilidges attached to them. Is there also a (painless) way of transforming this data into the new installation?

Hardware recommendation
by Mischa Diehm 05 Mar '14

05 Mar '14

Hi, first of all welcome to the list! we (UniBasel) use NAV for quite some while now and are very pleased with the possibilities NAV gives us. We use Debian as OS with the following Setup: root@urz-nav:~# uname -a Linux urz-nav 2.6.32-5-amd64 #1 SMP Fri May 10 09:44:53 UTC 2013 x86_64 GNU/Linux root@urz-nav:~# cat /etc/debian_version 6.0.7 root@urz-nav:~# dpkg -l | grep nav ii nav 2+3.14.15-1 Network Administration Visualized A problem we have since a while is that our system is permanently under a lot of load (mostly CPU bound) and we haven't really found a way to reduce the pressure. The hardware we use is a hp blade (ProLiant BL460c G6) with: Intel(r) Xeon(r) Processor X5550 (4 Cores/ 8 Threats) (8M Cache, 2.66 GHz, 6.40 GT/s Intel(r) QPI) and: root@urz-nav:~# free total used free shared buffers cached Mem: 12321700 11673596 648104 0 387768 9123748 At the moment we have 1460 active Devices (mainly Cisco Switches). Around 30 or 40 are OVERDUE in: https://urz-nav/report/lastupdated So my question is, do you have any good experience with HW-systems that are actually dealing with this amount of devices or is there any tuning possibility (without losing functionality) we could try to reduce the pressure on the system?

The third beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b3 I'm also happy to report that the Norwegian University of Science and Technology and the University of Agder have both signed on as beta testers using the virtual appliance. Here's the changelog summary of today's release: Bugfixes: * LP#1270095 (APC sensors stored at wrong precision) * All VLAN utilization graphs produced error messages in b2. User-visible features and improvements: * Inserted the new NAV logo, and completely reworked the page footer. * New NAV blog feed widget added as default. * UI clean-ups and improvements in front page widgets, login page, Geomap, SeedDB, Messages, PortAdmin, Radius, Syslog Analyzer, IP Device Info, room photo database, personal preferences page and others. * Fixed Internet Explorer 9 brokenness. * Tool descriptions have been completely re-authored, and are now also available as a subheading inside each tool. A Debian package has been uploaded to our APT repository. We have not yet built a new virtual appliance, but you can upgrading your existing one using the regular apt-get route. The updated package introduces a dependency to `python-feedparser`, so you may need to either use 'apt-get dist-upgrade' or 'apt-get install nav' to force an upgrade of the nav package (after issuing 'apt-get update', of course).

The NAV Blog
by Morten Brekkevold 22 Jan '14

22 Jan '14

Hi all, we thought we should do as everybody else on the Internet, so this week we launched our own NAV blog. As NAV developers, we hope to blog about what we're working on behind the scenes, be it either related to network management or software development, but it will always be related to our work on NAV. Our first entry is up on http://blog.nav.uninett.no/ - have a read :-) -- Morten Brekkevold UNINETT

Announcement: NAV 4.0 beta 2 released
by Morten Brekkevold 09 Jan '14

09 Jan '14

The second beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b2 This release fixes three bugs reported against the first beta version, as well as improving the UI of several of the tools: * LP#1262644 (seeddb bulk import does not work) * LP#1263040 (ipdevinfo should not crash when Graphite-web is not reachable) * LP#1267464 (NAV 4 must provide a tool for migrating RRD data from NAV 3) The most important of these changes is the addition of the conversion tool to migrate data from NAV 3's RRD files into NAV 4's Graphite metrics. This was held back from b1 due to license compatibility issues, which should now be resolved. Instructions for migrating RRD data has been added to the release notes, but in short, they refer to the migration guide available at [1]. A Debian package has been uploaded to our APT repository. We have not yet built a new virtual appliance, but upgrading your existing one should be simple matter of "apt-get update && apt-get upgrade". As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy NAVing everyone! [1] https://nav.uninett.no/doc/4.0/howto/migrate-rrd-to-graphite.html -- Morten Brekkevold UNINETT AS

Start automatically NAV services

Hi, Some NAV services don't start automatically (like "ipdevpoll") when my NAV server starts. I have to do it manually with the command "nav start ipdevpoll", and so on for each service not started. Do you know how can I make them start automatically ? Thank you very much :) Cédric.

Announcement: NAV 4.0 beta 1 released
by Morten Brekkevold 20 Des '13

20 Des '13

We are proud to present the first beta release of the NAV 4.0 series, which is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b1 This release introduces some major changes to NAV, signalled by the switch from major version 3 to 4. The two big changes are: 1. The complete replacement of Cricket as a 3rd party tool for statistics collection and graphing. NAV 4 collects the statistics using the already existing ipdevpoll SNMP collector, and uses Graphite as a 3rd party service for storing and graphing this data. This also means NAV no longer uses RRDtool for storing time-series data. 2. A full design overhaul of the web interface, using the Foundation CSS framework. As this is a beta release, not all parts of the interface have been fully reviewed for necessary changes yet. We are reviewing the design changes weekly, with help from the experienced interaction designer Christine Sætre. The full release notes for this release can be read at [1]. You are also advised to read the updated installation docs at [2]. We hope as many people as possible are interested in testing our upcoming beta release of the 4.0 series. We will be providing a binary package for Debian Wheezy shortly. More importantly, we will also provide a virtual appliance, complete with a Graphite installation, which should be deployable on most popular virtualization platforms. Using the instructions from [3], you should be able to easily migrate your production database to a (virtual) test server so you can test the new version without disrupting your current production installation. We will continue to support the 3.15 series for a good while after the final 4.0.0 release, but we have not yet decided how long the support period will be. As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy NAVing everyone!

New repository for the NAV Debian package
by Morten Brekkevold 30 Okt '13

30 Okt '13

As some of you may already have read, Werner is stepping down as the official maintainer of the NAV Debian package, mainly due to time constraints. UNINETT uses these packages in production, so as a result, I've taken over as package maintainer on behalf of UNINETT, and I will be building on the already awesome work Werner has put in. As of today, we've published our own APT repository for the packages we build. Instructions for using the repository can be found on the NAV wiki, at [1] . For those interested in the package sources, everything is version controlled and published on Bitbucket, at [2]. I've also enabled the issue tracker for that repository, so that any problems with the package itself can be reported there. Happy NAVing, everyone!

Announcement: NAV 3.15.0 released
by Morten Brekkevold 17 Okt '13

17 Okt '13

The initial release of the new NAV 3.15 series is now available for download at Launchpad: https://launchpad.net/nav/3.15/3.15.0 This feature release brings many changes to NAV, including, but not limited to: * mod_python is no longer required; mod_wsgi is the new recommended way to deploy the NAV web interface. * Devices' conceptual layering of interfaces is now collected and presented in ipdevinfo. This enables you to, among other things, see which physical ports comprise a port- or etherchannel. Some vendors also use this to show which physical switch-ports are forwarding packets to/from a given VLAN interface. * The Netmap tool has been redesigned and re-engineered. Multiple improvements have been made based on user feedback. * The Netmap contents can now be exported/downloaded as an SVG file, but this feature is currently only supported by the Google Chrome browser. * Multiple parallel links are now indicated by the Netmap by two parallel black markers drawn across the link in question. Details of the underlying links are are now properly displayed when clicking on the link line. * Interactive next-hop neighbor map in new ipdevinfo tab. * "What-if" analysis in new ipdevinfo tab displays devices and organizations that may be affected if the selected device goes down. Based on NAV's topology information. * Images with descriptions can be uploaded and attached to rooms. Useful for, among other things, photo-documenting the contents of wiring closets. * Subcategories have been replaced by cross-category device groups. Arbitrary selections of IP devices can be organized into device groups. * Potentially out-of-date CAM and ARP records are highlighted in Machine Tracker search results. * Community strings are censored in SeedDB IP Device listing. * New program enables streamlined dumping and reloading, with optional filtering, of the NAV PostgreSQL database. This simplifies beta testing of new NAV versions by copying the production database to a test server. * 26 more metrics from APC UPS devices are now collected and graphed. Fixes for various reported bugs: * LP#1055383 (netmap saves a new view when it should update view) * LP#1057423 (netmap algorithm indicator turns red when clicking on something in left bar) * LP#1062203 (ipdevpoll job configuration description) * LP#1165039 (Selecting a datasource for bulk threshold config intermittently fails with "internal server error") * LP#1169926 (Replace mod_python with Django/WSGI) * LP#1213818 (LDAP authentication crashes on non-ASCII usernames and/or passwords) * LP#1222666 ("Uptime" in ipdevinfo never resets) There are also various dependency changes, documented in the release notes. Please report bugs at https://launchpad.net/nav/+filebug Binary packages for Debian will be made available as soon as possible.

Please report bugs at https://launchpad.net/nav/+filebug Morten Werner Forsbring will be stepping down as maintainer of the Debian package, which is also the reason that no official package has been announced for the 3.15.0 release. For those of you already following Werner's repository at http://pkg-nav.alioth.debian.org, the wheezy-test archive there does contain a 3.15.0 package, built in cooperation between Werner and myself. As we are using the Debian package in production at UNINETT, we will be maintaining and releasing the Debian package ourselves in the future. More details will be announced shortly. Thank you, Werner, for all the work you have put into creating and maintaining the Debian package thus far! Happy NAVing everyone! -- Morten Brekkevold UNINETT AS

Increase rommid column size table room
by Bruno Galindro da Costa 02 Okt '13

02 Okt '13

Morten, I need to add a roomid that has more than 30 chars. I've altered the size of rommid column in table room (at database level), but the HTML fields has a 30 chars limitation. Nav web has built on Django framework which is very nice ;), but I don't know where I can make this modification. *** EXPLANATION: Here at UFSC, we have devices in many places. Bellow has an example of devices physical location: UFSC (Santa Catarina's Federal University) Campus Trindade (City: Florianópolis - SC - Brazil) CCB (Biological's Science Centre) Morfologia (Morphology's Department) Secretaria da Morfologia (Morphology's Department Management Room) Lab. Virtual de Estudos Morfológicos (Virtual Laboratory of Morphological Studies) We have added UFSC as a Parent Organization for Campus Trindade (there are many other campus, but I try to focus only on Trindade): [image: Imagem inline 1] CCB (Biological's Science Centre) was registered as a location: [image: Imagem inline 2] All the other information we are try to register as a room. Here we are experiencing the mentioned limitation problems. We have thought to register these information as a Location, but the Location information isn't displayed at ip device info screen nor at Edit IP Device screen. Unfortunately, this complicates our work. Here is a simple room registry example: CCB_Morfologia_Lab. Virtual de Estudos Morfológicos:CCB::Contato - Gianor - 2320:Na Morfologia/Anatômico, passando a secretaria de morfologia, entre os anfiteatros:::-27.60106, -48.52385 If I try to split "CCB_Morfologia_Lab. Virtual de Estudos Morfológicos" into two fields: (rommid: CCB_Morfologia , description: Lab. Virtual de Estudos Morfológicos) this will cause a contraint violation, because I'll need to add another device that lives in Morphology's Department, but in another place (Morphology's Department Management Room for example). My sugestion is: 1 - add a field called Location in Edit IP Device screen which filters the Room field. 2 - add Location and Parent Organization information at IP Device Info. We can help you and your development team to make these modifications (and maybe others). This could be a nice starting. I hope you understand our necessity and help us to put NAV in production for replace Whatsup Gold. :) -- Att. Bruno Galindro da Costa

Restrict mcc netbox interfaces
by Bruno Galindro da Costa 26 Jul '13

26 Jul '13

Hi! Unfortunately my network devices are very slow to anwser snmp get-bulk requests, causing cricket process run indefinitely. Is it possible to implemment a new feature to restrict the number of interfaces generated by mcc.py? So, I can tell to mcc.py to only generate trunk interfaces config. Searching in source code, i've found this piece of code. I think the bold line that must be upgraded to provide this feature: def create_interface_config(netbox, targetdir, module): """Create config for this netbox and store it in targetdir returns: a list of containers """ LOGGER.info("Creating config for %s" % targetdir) config = CONFIG[module] * interfaces = netbox.interface_set.select_related('netbox').filter(* * **config['filter']).distinct().order_by('ifindex')* Until this feature can be applyed, is there any workarround that I can do to acomplish that? All of my switches trunk ports is standardized to be in the last ports (22 to 26 and 44-48)... -- Att. Bruno Galindro da Costa

NAV dashboard teaser
by John-Magne Bredal 01 Jul '13

01 Jul '13

Hi NAV'ers! In an effort to break the silence on this mailing-list I decided to post a teaser of what we're working with regarding new layout and user friendlyness. The attached image shows the last iteration of the front page. The plan is to make it customizable for the individual user by provinding a set of "Navlets" or widgets that show updated information and provide shortcuts to NAV's tools. A user can add, remove and reorder Navlets to create the dashboard he wants. Some of the Navlets are individually configured, for instance to display the graph or the status the user finds most interesting. A Navlet can be set to auto-update periodically so that the dashboard can be used on always on screens in network monitoring environments. This is a work in progress. Any input from you is appreciated! NB: The logo is a placeholder. Regards -- John-Magne Bredal UNINETT AS

Announcement: NAV 3.14.1592 released
by Morten Brekkevold 30 Mai '13

30 Mai '13

NAV 3.14.1592, another maintenance release of the endless NAV 3.14 series is now available for download at Launchpad: https://launchpad.net/nav/3.14/3.14.1592 This release changes some aspects of how Cricket is configured to collect traffic statistics, so we have added a couple of important upgrade notes: * The Cricket trees `switch-ports` and `router-interfaces` have been consolidated into a single `ports` tree, where all physical ports' traffic stats now also are collected. After running the usual `syncdb.py` command, you should run `mcc.py` once manually (as the navcron user) to ensure the Cricket config tree is updated right away. When everything is up and running again, you can optionally delete the `switch-ports` and `router-interfaces` directories from your `cricket-config` directory, as they are no longer used by NAV. * NAV now supplies its own `subtree-sets` configuration to Cricket. If you have made manual changes to your Cricket collection setup and/or this file, you may need to update your setup accordingly. This release fixes the following reported issues: * LP#1165193 (Prefix Matrix Doesn't Handle HSRP) * LP#1165206 (ARP Entries on HSRP Subnets are Double Counted) * LP#1169553 (Consolidate switch-ports, router-interfaces and physical port traffic statistics in Cricket) * LP#1169837 (servicemon debug logs no matter what the log level is set to) * LP#1169872 (VRRP/HSRP plugin is not enabled by default) * LP#1169986 (ipdevpoll spins in its tracks and doesn't reconnect on database connection loss) * LP#1170221 (Subnet matrix crashes with AttributeError when only one scope prefix is registered) * LP#1170291 (Mac search + DNS crashes with AttributeError in NAV 3.14.159) * LP#1170329 (eventengine dies on loss of database connection) * LP#1170374 (Alertengine dies on loss of database connection) * LP#1170634 (The SMS daemon dies when database connection is lost) * LP#1172204 (Device history crashes with NameError on invalid date input) Please report bugs at https://launchpad.net/nav/+filebug Binary packages for Debian will be made available as soon as possible.

I've been running NAV (3.14.15 on Debian appliance) for a few weeks without any issues but recently I started getting errors when running the Layer 2 trace tool.

Bruk av NAV og uheldige konsekvenser for Cisco-utstyr

Single device configurations
by Bruno Galindro da Costa 15 Apr '13

15 Apr '13

Guys, is it possible to configure NAV to: 1 - ignore a single or a range of devices to be ignored from the polling process? I think this will be possible when we put it in maintenance mode. I'm right? 2 - apply per device ipdevpool's plugins intervals? According to docs, its is possible to set intervals for all devices but I hope that exists some other "hide" config to do that :) -- Att. Bruno Galindro da Costa

rsyslog, logger.conf and cisco devices
by Ted 10 Apr '13

10 Apr '13

I am running NAV ver. 3.14.15 (downloaded the virtual appliance and did an upgrade) but I am unable to get the syslog part to work (as well as cricket but that I am still researching) The original logger.conf points to /var/lib/nav/log/cisco.log - shouldn't that point to /var/log/nav? Anyway I changed that to point to /var/log/messages I also had to enable in rsyslog.conf to receive UDP messages by uncommenting the lines $ModLoad imudp and $UDPServerRun 514. When I do tail -f /var/log/messages I can see that the Cisco switches are sending messages. If I try to pull up the syslog messages through NAV however it tells me that there are no messages. Any pointers would be greatly appreciated.

Unmanaged devices
by Bruno Galindro da Costa 02 Apr '13

02 Apr '13

Hi! Question 1: Is it possible to change the device type? I know this information is gathered from device, but when the device has no snmp support, but only an ip address (like a printer), I need to specify it's type in the system to built more detailed and consistent reports. Question 2: How can I insert an unmanaged switch or hub in NAV? I need this because I want to know where this kind of devices are inserted in our network to planning a future replacement of it. Question 3: Where I can change the netmap device icons? The device icon is related to type or category? Would be great if it where possible to change the device's icon to reflect it's model.

Netmap broken in 3.14.1
by Corey Thompson 21 Mar '13

21 Mar '13

Just updated the Debian package to from 3.13.1 to 3.14.1 and netmap appears to no longer work, just the spinning wheel. Anyone else experiencing this? Haven't looked much further into it yet, but save myself some time if others have noticed the problem and have a solution. Also, (again, I haven't had time to look closely at it yet) is there a way to configure the geomap to plot only physical layer-2 connections? It is plotting vl1 connections to root hub along with the physical connections. Thanks for any assistance in advance, and I'll report if I find anything. -- Corey Thompson Technology Manager East Grand Forks Water and Light 1010 5th Ave NE East Grand Forks, MN 56721 218-399-3310 cthompson(a)egf.mn

We are running NAV 3.13.0 since 08.02.13 Some days ago something happened in our environment that caused eventengine to throw an error: 2013-02-13 17:08:57,887 [ERROR nav.eventengine.engine] Unhandled exception in plugin <nav.eventengine.plugins.boxstate.BoxStateHandler object at 0x804e170d0> ; ignoring it Traceback (most recent call last): File "/usr/local/nav/lib/python/nav/eventengine/engine.py", line 190, in handle_event handler.handle() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 52, in handle return self._handle_start() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 68, in _handle_start self._set_internal_state_down() File "/usr/local/nav/lib/python/nav/eventengine/plugins/boxstate.py", line 29, in _set_internal_state_down shadow = self._verify_shadow() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 189, in _verify_shadow netbox.up = (Netbox.UP_DOWN if netbox_appears_reachable(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 32, in netbox_appears_reachable target_path = get_path_to_netbox(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 82, in get_path_to_netbox path = networkx.shortest_path(graph, netbox, router) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/generic.py", line 124, in shortest_path paths=nx.bidirectional_shortest_path(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 138, in bidirectional_shortest_path results=_bidirectional_pred_succ(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 205, in _bidirectional_pred_succ raise nx.NetworkXNoPath("No path between %s and %s." % (source, target)) NetworkXNoPath: No path between <server> and <router> This happened for 5 servers all on the same GSW.

Announcement: NAV 3.13.0 final released
by Morten Brekkevold 07 Feb '13

07 Feb '13

A beta version of the next NAV feature release, version 3.13.0b1, is now available for download at Launchpad: https://launchpad.net/nav/3.13/3.13.0b1 The 3.13.0b1 release adds the following user-visible features and improvements: * The eventEngine has been rewritten to Python. This was the last remaining Java component of NAV, meaning Java is no longer needed for installing and running NAV. * VLANs are now searchable from the Navbar. * IPv4, IPv6 and MAC host counts for each VLAN is now graphed over time. * NAV is now able to detect and graph data from sensors on Cisco Nexus devices. * Maintenance tasks can now be configured to end automatically when all components involved in the task are up. * IP Devices that are down can be placed on immediate maintenance until up again directly from the status page. * Subscriptions to MAC address prefixes are now possible in Macwatch. Use with caution! And contains fixes for these reported issues: * LP#305435 (Sort by "Start time" or "End time" in machinetracker) * LP#305441 (Button for "Put on maintenance immediately") * LP#317800 (Color gradient to express utilization of IPv6 subnets) * LP#341703 (Manual detention does not pursue client) * LP#361530 (Arnold: Predefined detention does not exponentially increase detentions) * LP#744932 (Arnold should give warning if snmp write is not configured) * LP#833959 (make install overwrites nav.conf and db.conf) * LP#922793 (Possibility to set end time = "until device is up again " in maintenance) * LP#961097 (Don't list cancelled maintenance tasks in active list) * LP#961100 (Show component details in maintenance task list when there is only a single component) * LP#1057509 (Mouseovers with number of active IPv6 addresses in Subnet Matrix) * LP#1057511 (Get sensor information from CISCO-ENTITY-SENSOR-MIB) * LP#1062130 (NAV should graph IP address usage per prefix) * LP#1069773 (macwatch should be able to look for MAC address prefixes too) Remember, this is still beta status, and should not necessarily be considered production ready. 3.13 features two major rewrites, one for the eventengine one for the port blocker, Arnold. If you want to help us test the beta version, you are most welcome. Don't forget to check out the release notes, and please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible.

That's weird; the code involved here doesn't distinguish between device categories, it just checks what VLANs the device reports, if any.

Cisco Routers SNMP Trap issue
by Mattias Torsfred 07 Des '12

07 Des '12

Hi, I have setup a NAV 3.12.2 and started to add Cisco L2 and L3 equipment into the seed database. I use an other software to monitor the devices as well. When it comes to Cisco routers (not Cisco L3 switches) I get many SNMP Traps "Too many SNMP authentication failures . Check for hacking attempt on x.x.x.x" and "SNMP incorrect community name...". I am aware of the issue/design of NAV when it comes to VLAN browsing and that this might be the case. Is there any configuration I can set on Cisco routers or in NAV to prevent this kind of behavior? I need to have the traps in case there actual is an SNMP brute force attempt. Kind Regards Mattias Torsfred Systemconsultant Funn IT

overdue jobs
by Matej Gregr 23 Nov '12

23 Nov '12

Hello, I have noticed, that NAV is reporting jobs as overdue, even though a job end with success. I believe the problem is caused by trigger trim_old_ipdevpoll_job_log_entries, which should delete the old jobs from the ipdevpoll_job_log table. DELETE FROM ipdevpoll_job_log WHERE id IN (SELECT id FROM ipdevpoll_job_log WHERE job_name=NEW.job_name AND netboxid=NEW.netboxid ORDER BY end_time ASC OFFSET 100); When there are 100 log entries for a job in the nav database the trigger will delete the newest logged job instead of oldest one. I believe, that the ORDER BY clause should be DESC not ASC. Regards, M.

The newest feature release of NAV, version 3.12.0, is now available for download at Launchpad: https://launchpad.net/nav/3.12/3.12.0 The 3.12.0 release adds the following user-visible features and improvements: * The Netmap Java applet has been rewritten in JavaScript, with many improvements, including, but not limited to, saveable map layouts and VLAN topology tracing. Layer 2 and layer 3 maps are now separate, and elinks/peers can optionally be displayed on L3. * Searches in the navbar will now return results from rooms and interfaces, as well as IP devices. * New room view with powerful port overview, enabling sorting, filtering and exporting information to CSV files. * IP Device Info has been cleaned up, now with more information, navigateable via a tabbing interface. * A map of registered room locations with status indicators can now be embedded in the main page by removing the commented-out sections of the `welcome-registered.txt` file. * IPv6 traffic counters for router interfaces. Vendor support for this seems dismal at the moment, so keep nagging for software updates! If upgrading from previous NAV versions, new cricket configuration templates need to be copied; please read the release notes. * ipdevpoll now supports both VRRP and HSRP. * The maximum number of concurrent collection jobs in an ipdevpoll process can now be configured, which is useful in situations where the process runs out of resources such as file descriptors. * ipdevpoll job runs are now all logged to the database, enabling more details and analysis of job statuses in the web interface. ipdevinfo will now display a timestamp for each of the configured jobs, complete with status indicators and warnings for jobs that may be overdue. * The Maintenance and Messages tool have been migrated from mod_python to Django, and especially the former has received some improvements along the way. And contains fixes for these reported issues: * LP#736825 (Replace ip-hostname search in toolbar with a more generic searchbox) * LP#1039490 (Mixed IPv4 and IPv6 elinks are mis-labeled as lans) * LP#1040043 (Incorrect layer 2 topology in networks with VRRP routers) * LP#1043791 (MAX_CONCURRENT_JOBS needs to be configurable) * LP#1044321 (SNMP timeout value is not respected during Cisco community indexing) * LP#1046227 (Django >= 1.2 deprecation warnings) Don't forget to check out the release notes before/during/after upgrading to NAV 3.12.

NAV 3.11.4 is now available for download at Launchpad: https://launchpad.net/nav/3.11/3.11.4 This maintenance release contains fixes for 7 reported issues, as well as some performance improvements to the collection system: Bugfixes: * LP#644155 (Network Explorer never returns response to some searches) * LP#912276 (Device History Request-URI Too Large) * LP#996955 (All sensor stats are named "Sensor", and clutter the ipdevinfo view) * LP#997008 (Failed ipdevpoll jobs aren't properly rescheduled) * LP#997606 (add option to run each ipdevpoll job type in separate process) * LP#997980 (bad MAC for IPv6 addresses from Catalyst 6500) * LP#999606 (dhcping is not documented as requirement for DHCP service monitor) Various performance-related improvements: * Internal caching of collected SNMP variables pr. ipdevpoll SNMP session. * Various tweaks to avoid producing unnecessary SNMP queries. * Added database indexes for some potentially slow and frequently used queries. * Added ipdevpolld multiprocess option to run each job type as separate subprocess (enabling this will consume up to 60 PostgreSQL connections, be warned!) * An -n option was added to ipdevpolld. Used in combination with the -J option, ipdevpoll will run a single job for a single netbox as a foreground process. * When new jobs are added to the internal ipdevpoll job queues, boxes are prioritized in ascending order of last update time. I.e. ipdevpoll will run jobs first for boxes that are new or haven't completed an inventory job in a long time.

question about prefix
by Rene Romijn 30 Apr '12

30 Apr '12

Hi, Question, if I go to report/prefix I see all my networks and subnetworks and also a nice number of active ip addresses. I remember in de the past that when I clicked on the number of active ip addresses I got the list of all individual ip's. Now I got the main page of the machine tracker with the error message "this field is required". Is it somehow possible that it does give the list at once when you click the number? Regards, René

Debian package nav init sequence makes nav start before postgresql
by Roger Aas 13 Apr '12

13 Apr '12

Hi, I have a request for change for the init configuration for the NAV Debian package. Problem: When the nav server starts some nav modules fail to start up because the nav init script makes nav start before the postgresql database has started. Under /etc/rc2.d/ (2 is default run level on my machine) the nav script is named S03nav and the postgresql script is named S03postgresql. Since init starts the scripts first numerically (same numbers can be started concurrently I think), then alphabetically it means nav will start a little before postgresql making some nav modules fail to start because they can not contact the database. Editing the script /etc/init.d/nav and adding postgresql to the end of the Required-Start and Required-Stop lines, then running the command "update-rc.d nav defaults" fixes this. The lines will look then like this: # Required-Start: $local_fs $named $network $remote_fs $syslog $time postgresql # Required-Stop: $local_fs $named $network $remote_fs $syslog $time postgresql Best regards, Roger Aas Atea AS

GbE2c Ethernet Blade Switch
by Rene Romijn 03 Apr '12

03 Apr '12

Hi, Maybe a stupid question, but we have several type of switches/routers in our network, nav does a good job with recognizing the hp and cisco ports. But we also have some Gbe2c switches, they are sold by hp but the original is from another branche (wich I forgot). Nav does see the type of switch but it doesn't see the individual switch ports. I would realy like to see that nav/cricket also keeps track of those switchports. Kind regards, Rene.

NAV 3.10.1 We have several (but not all) routers and switches where cricket try to collect data fram OIDs the devices doesn't know anything about. I fail to find any similarities in type of device or OS-version between the devices. For a switch the offending lines in switches/navTargetTypes looks like this: targetType brusS101-sw.infra.uit.no ds = "c1900Bandwidth, c1900Bandwidth, c1900BandwidthMax, c1900BandwidthMax, mem5minFree, mem5minFree, mem5minUsed, mem5minUsed, sysUpTime, sysUpTime, c2900Bandwidth, c2900Bandwidth, c5000Bandwidth, c5000Bandwidth, c5000BandwidthMax, c5000BandwidthMax, cpu1min, cpu1min, cpu5min, cpu5min, hpcpu, hpcpu, hpmem5minFree, hpmem5minFree, hpmem5minUsed, hpmem5minUsed" view = "bandwidth: c1900Bandwidth c1900BandwidthMax c2900Bandwidth c5000Bandwidth c5000BandwidthMax, cpu: cpu1min cpu5min hpcpu, memory: hpmem5minFree hpmem5minUsed mem5minFree mem5minUsed, sysuptime: sysUpTime" Note that it tries to collect both c1900Bandwidth, c2900Bandwidth and c5000Bandwidth When I check the device via https://nav.example.com/report/netboxsnmpoid?netbox id=## I don't find any OIDs relating to Bandwidth at all.

Geomap has gone blank since the end of February
by Morten Brekkevold 14 Mar '12

14 Mar '12

It has been brought to our attention that NAV's Geomap has recently gone blank. Apparently, this is because OpenStreetMap has pulled their support for the Osmarender layer, which is one of the two OSM layers initialized and used by Geomap (the other being Mapnik). A post [1] on the OSM-dev list explains what has happened. As a response, we've removed the Osmarender layer from Geomap; this will be effective from the NAV 3.11.1 release, but if you wish to patch your current NAV installation to enable Geomap again, the patch is available at [2].

See LP#643544 for details. * ipdevpoll can now be made to run single job configurations from ipdevpoll.conf, to run in the foreground, and to log to stderr instead of its log file. * ipdevpoll will reset its log levels from logging.conf upon receiving a SIGHUP signal. * ipdevpoll will log the currently active polling jobs upon receiving a SIGUSR1 signal.

Using NAV as a source for rancid
by Sigurd Mytting 12 Mar '12

12 Mar '12

Hi! We´re looking into using rancid (http://www.shrubbery.net/rancid/) for keeping track of device configuration. I´d like to use the NAV database to build the rancid configuration. Currently I use dump.py, but I need more of the internal NAV data per device, most importantly I need to know the device vendor - cisco, juniper, alteon and so on. Is there an easy way to get a more complete dump of the NAV database? Cheers, -Sigurd

Sanitizing table cam in the nav database
by Nik Mitev 14 Feb '12

14 Feb '12

Hello, I have created a pilot installation of NAV, currently handling 16 production switches. It seems that the cam table, holding the MAC addresses seen on the switches is growing very fast and holding large amounts of redundant information, in some cases up to 250 entries per MAC address. I am looking for ways to restrict the amount of history kept, as we only need to know which switch/port a MAC is on, rather than a full history of online/offline status changes. This can of course be done by scripts, I was wondering though is there any relevant built-in functionality already present? Thanks, Nik

Timezone problem
by Adrian Bucurica 05 Jan '12

05 Jan '12

Hello everyone, We've just started to test NAV and I have a strange problem with the timezone reported in NAV. It seems that NAV reports all operations using timezone GMT+1 (Western Europe) but on localhost we have configured a different timezone: diff -s /etc/localtime /usr/share/zoneinfo/`cat /etc/timezone` Files /etc/localtime and /usr/share/zoneinfo/America/Chicago are identical We are using Debian Squeeze 64-bit and NAV 3.10 installed from source. What am I missing? Regards, Adrian

Issues with status-page and box down
by Ingeborg Hellemo 20 Des '11

20 Des '11

2 issues really: At the moment I have 3 boxes down, one of which is on maintenance. 1. The "Status now" box on the NAV front page shows also the box which is on maintenance as down. Is this a bug or a feature? NAV pre 3.9 was silent about boxes on maintenance on the front page. 2. https://nav.example.com/status/ shows correctly one box as on maintenance, but the "IP devices down" is empty! I have to click on the history-tag to find my two boxes (which went dows yesterday, but are still down). --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Differences in SNMP results between versions
by Seb Rupik 17 Nov '11

17 Nov '11

Hi all, I have been tasked with creating a new NAV (3.9.1) install. All appears to be fine until I compare it against the previous old (3.5.4) installation. The majoirty of our switches are Cisco 3750's nearly all stacked, but the new install doesn't seem to acknowledge this under 'IP Device Info' where the 'Modules' field shows '0', but the 'switch port status' table shows all interfaces spanning the stack. On the old install the 'Modules' field has the correct number and the 'Switch port status' shows the right number of separate modules. Looking under: 'Report-> Vendors -> Cisco' confirms that the new install is receiving less SNMP OIDs per switch stack; typically 75. Where as the old install is showing between 88-90 for the same stacks. Also in some cases the new install is not showing any returns under #mod, #swp, #gwp and #prefixes, where is does on the old install. Both installs are running libsnmp1.4-java; the old 1.4-5, and the new install 1.4.2-2. Would that account for the differences? What's the best way to test the two installs side by side in an output based comparison? Many thanks, seb.

Question for NAV Users with Cisco 3750 Stacks
by Greg Cooper 17 Nov '11

17 Nov '11

Hi, All. I'm looking for some input from anyone using NAV with Cisco 3750 switch stacks. If you have a stack of 2 or more 3750's and all the L2/L3 interfaces are being properly pulled from it by NAV, then would you mind sharing what version of IOS you are using? I think I may be running into an SNMP issue with the particular version of IOS I'm on. I get timeouts when querying the 3750 via SNMP. I can do an snmpwalk from the NAV server to the device, and it runs for a while, but it will sometimes time out. Thanks! Greg

NAV reference committee
by Morten Brekkevold 15 Nov '11

15 Nov '11

Hello all, I just wanted to say a few words about the NAV reference committee, which was established just last week. Those of you who aren't one of UNINETT's NREN customers in Norway may or may not be aware that NAV is one of the many free software offerings to our customers. We even operate remote NAV servers as a service for ~30 of our smaller customers. We try to concentrate our development efforts to meet the demands of our customers in higher education (HE), and since this is a free software project we also cooperate with some of our HE customers, who regularly contribute to and maintain parts of NAV (some by their own volition, others commissioned and paid by us). It is not always clear what the customer wants. Some of our customers are very vocal about what they want, others keep quiet, maybe spilling their guts in the occasional face to face meeting (or maybe not even then). So we've revived a several years old idea to establish a kind of committee of reference for NAV development. This committee consists of representatives from our HE customers, and would be responsible for collecting, massaging, filtering and prioritizing wishes for further NAV development from the HE community. This committee was established on Thursday 10th November here in Trondheim, and consists of the following representatives: * Vidar Faltinsen, UNINETT (committee leader/secretary) * Morten Brekkevold, UNINETT (lead NAV developer) * Gro-Anita Vindheim, Norwegian University of Science and Technology * Børge Brunes, University of Tromsø * Jan Sigurd Refvik, University of Oslo * Rune Kittelsen, University of Agder * Peder Sefland, Volda University College The committee will publish its work on the web at [1], were you can already find the minutes from the inaugural meeting. As we're the Norwegian NREN, the committee's working language will be Norwegian - if you don't speak Norwegian, you may want to try using Google Translate or similar services to translate those pages if you want to see the details of what's going on (although automatic translation may confuse more than it helps ;-) ). Nevertheless, the results of the committee's input will be visible in how we prioritize bug reports and blueprints on our Launchpad project page [2]. Have a great day!

Twisted SNMP Patch Question
by Greg Cooper 15 Nov '11

15 Nov '11

Hello, I have a question about this from the NOTES: The latest TwistedSNMP version (0.3.13) contains a bug that manifests in table retrieval operations. Timeouts and retries aren't handled properly, and this may cause slow or otherwise busy devices to be bombarded with requests from NAV. The `contrib/patches` directory contains a patch for TwistedSNMP that solves this problem. The patch has been submitted upstream, but not yet accepted into a new release. Alternatively, you can install `pynetsnmp` for improved performance. I think I am running into the Twisted SNMP timeout issues talked about here. So my question is this: When it says, "Alternatively, you can install pynetsnmp for improved performance" does that mean that instead of patching TwistedSNMP, i can just do an apt-get install pynetsnmp and then I don't have to worry about the Twisted SNMP library's problems? If so, do I have to uninstall twisted SNMP? If I still have to patch Twisted, then what is the best way for me to go from using the standard debian packaged TwistedSNMP to using the patched one I build from scratch? I don't want to be stuck where I have both installed, but it is still using the old version. Thanks in advance, Greg

Cricket-config and GW which does not support ifName
by Ingeborg Hellemo 14 Nov '11

14 Nov '11

The old (3.5) NAV's makecricketconfig.py used interface-indexes directly when collecting router-interface data. The new (3.8) NAV's mcc.py uses a map based on ifName: map interface-name base-oid = ifName match = %ifname% We have a couple of GWs (firewall nodes running some variation of Linux) which does not support ifName. This breaks the collection of router-interface. I know what is needed of a work-around (use ifDescr instead), but wonder if we are the only ones who have this kind of (old) equipment? Will anyone be interested in patching mcc.py or shall I just implement a local hack? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

ipdevpoll daemon 3.9.1
by izar＠condornet.sk 14 Nov '11

14 Nov '11

Hi all, I'm sorry for spam, but i would like to make sure that it's a real bug not just my mistake/misunderstanding before filling in the bug into lauchpad. I upgraded NAV to 3.9.1 this monday (deb 5.0) from rep. and I noticed that ipdevpoll job is not running as it supposed to. If I understand it right, then ipdevpolld should be daemon process running all the time, however in 3.9.1 it's not: ./ipdevpoll status ipdevpolld does not seem to be running... If I restart NAV ,then ipdevpoll runs just once .... Thanks, milo

ipdevpoll does not set sysname unless snmp is enabled
by Ingeborg Hellemo 14 Nov '11

14 Nov '11

During migration from old NAV (3.5.6) to new NAV (3.9.1) I "Bulk import"-ed all our hosts. I notice that ipdevpoll does not set correct sysname on hosts that does not run a configured snmpd. nav=> select * from netbox where ip='129.242.5.142'; netboxid | ip | roomid | typeid | deviceid | sysname | catid ----------+---------------+--------+--------+----------+---------------+------- 1100 | 129.242.5.142 | ma | | 87934 | 129.242.5.142 | SRV This means I now have several hundred boxes (mostly windows servers, virtual IPs and misc "stuff") lacking a proper sysname, even though they are registered i DNS. ipdevpoll.log: 2011-08-31 10:07:02,584 [WARNING plugins.dnsname.dnsname] [inventory 129.242.5.142] Box dnsname has changed from u'129.242.5.142' to 'radius1.uit.no' 2011-08-31 10:07:36,612 [ERROR jobs.jobhandler] [inventory 129.242.5.142] Job 'inventory' for 129.242.5.142 aborted: SNMP request timed out If I edit the host via the Seed DB web interface the correct sysname is saved: nav=> select * from netbox where ip='129.242.5.142'; netboxid | ip | roomid | typeid | deviceid | sysname | catid ----------+---------------+--------+--------+----------+----------------+------ - 1100 | 129.242.5.142 | ma | | 87934 | radius1.uit.no | SRV I presume this is a bug. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

network time is incorrect on cricket
by Ryan Lin 14 Nov '11

14 Nov '11

hi all, we have installed nav on one of our servers. everything is functioning properly except the time on the cricket. the time on the cricket is showing the UTC time. i would like to change it to the PDT time, but don't know how as there is no documentation available on how to change the time in nav. the server that's hosting the nav is synchronized to a public NTP server, so there is no issue with that. does anyone know how to correct the time in cricket on nav? thanks.

Hi I am trying to get the switch information of an IBM Bladecenter. The switch modules are Nortel Networks Layer 2-3 GBE Switch Module(Copper). OID is 1.3.6.1.4.1.1872.1.18.1 Is there any way to make the data acquisition of this type of switch? In the "IP Device Info" i saw 0 ports an the cricket have no data. There is some workaround for this type of switch? Best Regards

IPv6 Address

I'm running the NAV 3.8.6 and I get inconsistent reporting of IPv6 hosts. Some show up, others do not, even though they appear in the Cisco show ipv6 neighbor results. I don't see this problem with IPv4. Is this a known issue? Workarounds?

Bulk updates of database
by Sigurd Mytting 15 Jun '11

15 Jun '11

Hi! Due to organizational changes I need to update names of about 250 locations and change organization on about 800 devices, is there any way to do this without removing/adding them all? My first thought is SQL, is that the way to go? If so, there is 375 tables in the database, hints on what to update would be appreciated! Cheers, -Sigurd

For many years, we've asked NAV users to send us a postcard to tell us they use NAV (see: http://metanav.uninett.no/postcard). Up until now, we've received a total sum of 0 (zero) cards :-( I just want to send a shout-out and a big thanks to Matěj Grégr, from the University of Brno in the Czech Republic, who recently sent us no less than _two_ postcards :-) These are now proudly on display on the window facing the hallway outside my office: http://yfrog.com/h8qbqgxj -- Morten Brekkevold UNINETT

Announcement: NAV 3.9.0b1 released
by Morten Brekkevold 20 Mai '11

20 Mai '11

A beta version of the upcoming 3.9 series of NAV, version 3.9.0b1, is now available for download at Launchpad for those who wish to test it: https://launchpad.net/nav/3.9/3.9.0b1 The 3.9 series include these improvements: User-visible features and improvements: * NAV's threshold monitoring feature has finally been completed - Threshold Manager is a new web tool that allows adjusting threshold values for individual statistical data sources. Alerts generated by the threshold monitor can be subscribed to in users' alert profiles. * MAC Watch is a new web tool that maintains a watch list of MAC addresses. Whenever a watched MAC address appears on your network, NAV will send an alert that can be subscribed to. * ipdevpoll can now retrieve VLAN configuration from Extreme Networks devices. * ipdevpoll can now optionally use the pynetsnmp library as an alternative to the TwistedSNMP/PySNMP combination. pynetsnmp is a ctypes binding to the well-known NetSNMP library, and should noticeably improve performance if used. * Layer 2 topology discovery has been rewritten from scratch, due to both problems with the results of the old discovery code and problems with maintaining the old code. Bugfixes: * LP#739718 (ifName should be derived from baseport number if not available) More changes may still make it into the final release.

How to connect devices in Netmap view
by Royke 30 Mar '11

30 Mar '11

Hi, I try to connect between routers and switches within our network so I can view it in Netmap view on the toolbox. I've read the guides in http://metanav.uninett.no/subnetsandvlans#guide_lines_for_configuring_route…. I've create the vlan and change the description on the routers and switches to match the requirement based on the guidelines. However, I'm unable to connect the routers and switches on the netmap. The devices on the netmap are not connected and seems like "flying" on it's own and hard to capture to view all devices at the same time. Could you give me a hint, for example how to connect between two devices and view it correctly on the netmap view. Thanks. Regards Royke

Rename interfaces?
by Joachim Tingvold 21 Mar '11

21 Mar '11

Hi, Is there a way to rename the 'interface'-fields on a switch? We have some (really) old switches (Netgear FSM726) that has really long interface-names; "FSM726 Management Switch 10/100 Mbps Ethernet Network Interface 1", which kinda breaks the "Switch port status"- and "Switch port activity"-tabs on the "IP Device Info"-page of the devices in question. Could I change this in the DB in some way? Or will it just be overwritten next time navcron runs? -- Joachim

Adding organization; "This field is required"
by Joachim Tingvold 15 Mar '11

15 Mar '11

Hi, I have a weird problem, I think. I'm trying to add a new organization, but it keeps telling me that "this field is required" beneath the "Parent" dropdown-list. However, the only choice in that list, is "--------". This might be a really stupid question, but I can't seem to get it to work... I'm running NAV 3.8.2 on Debian Squeeze. -- Joachim

Announcement: NAV 3.8.2 released
by Morten Brekkevold 07 Mar '11

07 Mar '11

NAV 3.8.2 is now available for download at Launchpad: https://launchpad.net/nav/3.8/3.8.2 This is a maintenance release - here is an excerpt from the changelog: - This maintenance release fixes compatibility with newer versions of Django and Cheetah. - Changelog for 3.8.1 forgot to mention the addition of a new "offline devices" report. The report lists serial numbers of devices known to NAV, but now appear to have been shelved. - NOTE: Users on upgraded installations should update their status preferences. A missing setting in the default preferences assigned to all new users would cause the status system to not display devices on maintenance in the "maintenance" section unless they were actually down or in shadow (as described in LP#723688). After the upgrade, go to `Status` -> `Preferences` -> `IP Devices on Maintenance` and add `Up` to the list of states to display. This choice was previously not enabled. Bugfixes: * LP#591602 (Endtime in maintenance period overwritten by a shorter maintenance period) * LP#720669 (can't add components to maintenance task when existing components have been deleted) * LP#721270 (CSRF Verification Fails on Django 1.2) * LP#721273 (Multiple NAV pages crash on non-ASCII chars under Cheetah 2.4) * LP#723619 (Maintenance crashes when adding multiple netboxes to a task) * LP#723688 (Status doesn't show devices on maintenance) * LP#724266 (MachineTracker inactive search says all IPs are inactive) * LP#724322 (netbox.uptodate is not altered when saving in seeddb) * LP#726402 (Rooms should be listed alphabetically when editing IP devices) * LP#726472 (portadmin should report error when snmp write is not available) * LP#726524 (prefix net type classification may be wrong on first discovery) * LP#728336 (`nav version` cannot find version information in NAV 3.8) Please report bugs at https://launchpad.net/nav/+filebug :-) A binary package for Debian 5 (Lenny) will be made available as soon as possible.

Relations between netbox, user and vlan to make vlans show in PortAdmin?
by Stokkenes Vidar 17 Feb '11

17 Feb '11

Hello there, After reading the release notes of NAV 3.8.0 I was thrilled to see that PortAdmin/vlanAdmin had finally been merged with NAV in this release, and swiftly upgraded our production NAV server to the 3.8.0. Now what I don't get, is the relation required between the netbox you want to "operate" with PortAdmin/vlanAdmin, the user and the VLAN. I have already tested with several switches with the same organization membership as my own account (who also is a NAV administrator) but no matter what I do, I never get any available VLANs on my PortAdmin tab on any switch or port (as you can see here: http://dl.dropbox.com/u/9962750/portadmin.png) Am I missing something fundamental in terms of relations required between the netbox, user and vlans? Best regards, Vidar Stokkenes

NAV 3.8.0 is now available for download at Launchpad: https://launchpad.net/nav/3.8/3.8.0 This is a feature release, which includes the following changes: User-visible features and improvements: * The database schema can now be kept updated automatically using the new `syncdb.py` program. Please see the `NOTES` file, and run the program as soon as you've upgraded. * NAV can now configure descriptions and access VLANs on your switch ports when an SNMP write community is set for a switch. This functionality is accessible through the IP Device Info tool. * SeedDB has been rewritten to use the Django framework (and has subsequently been reduced from nearly 5000 lines of spaghetti code to just below 2000 maintainable lines). * The number of concurrent ipdevpoll jobs can now be limited on a per-job basis, to ease the load on your system if so desired. See the annotated `ipdevpoll.conf` file.

What does "Traffic in on switchports" show?
by Lars Kulseng 11 Jan '11

11 Jan '11

Hi I use NAV to, among other things, produce a monthly report about the usage statistics in our network. For this I use Statistics -> "Traffic in on switchports" + "Last Month". What does the resulting view show? Is it the average amount of traffic over the last month, or is it the total, or something else? I can't quite make the numbers add up on the different switch ports.

Cricket trouble/optimizing
by Sigurd Mytting 17 Des '10

17 Des '10

Hi! Running NAV 3.7.0 on Debian 5-64-bit, about 700 switches and routers currently in NAV. There has been a lot of weird stuff (trouble) happening with Cricket after going from the latest in the 3.5-series up to 3.7, some things got better from 3.6 to 3.7, but not all is perfect. Not complaining, just a summary from my point of view over the last months of releases. About a week ago my Cricket graphs just stopped and after some debugging I found the Cricket-cronjob run as navcron dies after a while and leaves a lock-file, cleaning it up and doing some optimizing (separating switch and router interfaces, and system values into separate cronjobs) I found the cronjobs still dies and leaves lock-files. First of all; anyone else seeing the Cricket collector dying? (In my case just about on every run.) Second; Anyone have a good tip on how to tune Cricket to run a sensible number of jobs to get thru it all in a sensible amount of time? Currently, if the largest job (switch interfaces) don't die after only a few minutes it usually runs for 25-30 minutes. NAV in my environment isn't really a production system, but my pet-project provides more accurate and sensible information than any system we have in production so I'll hang on to it as long as I can. Any input appreciated! Cheers, -Sigurd

Trouble with NAV 3.70 ,NFSEN on Debian 5

Hi, I have installed Debian 5-64 bit on a virtual machine. On top of that NAV 3.7.0 is installed , also NFSEN 1.3-5 and NFDUMP 1.6.1p1 Everything work as expected , but not graphs is generated through Cricket 1.0.5-9 The logs show errors from NfSenRRD.pm : Unable to create graph, no such file or directory. The graph windows in Nav is displayed , but no data is available visually. After googling a lot of users see the same problems as I have experienced. They all have downgraded lots of libraries in Perl and Cricket. Anyone done this setup with success on Debian 5.

3.6.0 mcc character encoding
by Sigurd Mytting 12 Okt '10

12 Okt '10

Hi, upgraded to 3.6.0 yesterday - it looks great! But there is a small problem: it seems mcc won't handle norwegian characters in port descriptions. 2010-10-09 09:35:58,708: [ERROR] nav.mcc.utils - Could not encode KVM Str�mskinne 1 to latin-1: 'latin-1' codec can't encode character u'\ufffd' in position 7: ordinal not in range(256) I don't really care about the description beeing correctly displayed, but mcc stops after this and no more cricket config is generated. Looks like this happens when convert_unicode_to_latin1 in nav/mcc/utils.py returns the unicode object instead of a latin-1 string. My workaround is to just return an empty string instead of the unicode object. Thanks for all the work you guys put into NAV, truly exceptional software solving everyday problems for a lot of us!

Issues with database upgrade from 3.5 to 3.6
by Morten Brekkevold 12 Okt '10

12 Okt '10

Hi, This is a notice to those who have previously upgraded NAV from 3.4 to 3.5 and will be upgrading to 3.6 now. We've received some reports from users on IRC about errors during the attempt to upgrade the SQL schema from NAV 3.5 to 3.6. As we're on the brink of upgrading multiple deployments of NAV among our customers, we're seeing the same problems ourselves. During the upgrade from 3.4 to 3.5, a lot changed in the database. Most notably, the multiple databases were merged into one. But also, several indexes were renamed. For some reason, not all of these renames have stuck with some PostgreSQL installations. We really have no idea why; all the rename statements are present in the upgrade script 3.5.0.sql, and they're all run in the same transaction. If any of them failed, the entire transaction should have been rolled back and all the changes thrown away, and we would have heard of it. If you receive an error that looks like this while upgrading the schema to 3.6.0, you are affected by the problem: psql:3.6.0b1.sql:433: ERROR: constraint "accountnavbar_pkey" does not exist The problem can be fixed by re-issuing all the index renaming statements from 3.5.0.sql using psql almost the same way as you would during the upgrade. Connect to the nav database using "psql <navdb> <navuser> <password>" (the db name, user name and password can be found in db.conf), and issue the following ALTER statements: ALTER INDEX logger.message_pkey RENAME TO log_message_pkey; ALTER INDEX logger.message_origin_btree RENAME TO log_message_origin_btree; ALTER INDEX logger.message_time_btree RENAME TO log_message_time_btree; ALTER INDEX logger.message_type_btree RENAME TO log_message_type_btree; ALTER INDEX logger.type_pkey RENAME TO log_message_type_pkey; ALTER INDEX logger.type_priority_key RENAME TO log_message_type_priority_key; ALTER INDEX account_pk RENAME TO account_pkey; ALTER INDEX brukernavn_uniq RENAME TO account_login_key; ALTER INDEX accountgroup_pk RENAME TO accountgroup_pkey; ALTER INDEX alarmadresse_pk RENAME TO alertaddress_pkey; ALTER INDEX brukerprofil_pk RENAME TO alertprofile_pkey; ALTER INDEX preference_pk RENAME TO alertpreference_pkey; ALTER INDEX tidsperiode_pk RENAME TO timeperiod_pkey; ALTER INDEX utstyrgruppe_pk RENAME TO filtergroup_pkey; ALTER INDEX utstyrfilter_pk RENAME TO filter_pkey; ALTER INDEX matchfield_pk RENAME TO matchfield_pkey; ALTER INDEX filtermatch_pk RENAME TO expression_pkey; ALTER INDEX queue_pkey RENAME TO accountalertqueue_pkey; ALTER INDEX navbarlink_pk RENAME TO navbarlink_pkey; ALTER INDEX accountnavbar_pk RENAME TO accountnavbar_pkey; ALTER INDEX privilege_pk RENAME TO privilege_pkey; ALTER INDEX privilegename_uniq RENAME TO privilege_privilegename_key; Some of them may fail with an error message like 'relation "xxx" does not exist', but that is just an indication that the rename stuck the first time around. Exit psql and try the schema upgrade again. -- Morten Brekkevold UNINETT

Install issues: Could not find the nav.startstop module
by Justin Callistini 17 Aug '10

17 Aug '10

Greetings! I am on my third attempt of installing NAV 3.5.6 on a Ubuntu 10.04 server 64bit machine and have followed the Debian cookbook each time, but to no avail. Everything seems to install just fine, but when I attempt to start NAV it gives this fatal error: testuser@metanav-test:~$ sudo /etc/init.d/nav start Starting Network Administration Visualized: Fatal error: Could not find the nav.startstop module. Is your PYTHONPATH environment correctly set up? testuser@metanav-test:~$ Upon install, the PYTHONPATH environment variable isn’t initialized, but I have tried manually adding a python directory but still no good. Other paths that I have used are: $PYTHONPATH:/usr/lib/pymodules/python2.6/nav/ $PYTHONPATH:/usr/share/python-support/nav/nav/s Any ideas what the issue could be with starting NAV?

Strange Python Errors after Upgrade to latest Beta
by Rudolph Bott 17 Aug '10

17 Aug '10

Hi List, I upgraded my 3.5.4 installation of NAV to the latest Beta (3.6.0b4) and ran into the error posted below. I configured NAV from scratch, updated the Database with the pgsql scripts and everything seems to be fine: I can login using a LDAP backend, see the welcome page and user information etc - but as soon as I click on 'Toolbox' I receive an error message. It thought it might be related to the 'ForgetSQL thing' but according to this list, ForgetSQL is not a requirement any more (starting with 3.6) - or am I wrong on this one? My system is Ubuntu 9.04, running with Python 2.5.4 and 2.6.2 installed.

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!

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

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!

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

automatic Switch configuration rediscovery
by Rudolph Bott 19 Mar '10

19 Mar '10

Hi List, is there a way to trigger some sort of automatic device rediscovery? We recently changed a lot of ports on our cisco 4500 series switches to trunk mode and although this happened more than 2 weeks ago, NAV still does not reflect these new settings in the switch overview/IP Device Info. Is NAV even supposed to see these kind of changes or might I be hitting a bug? We are currently using NAV 3.5.4 - I know its not the latest release but at least its close to it ;-) On top of that I couldnt find any hints regarding this problem in the latest changelog. -- Mit freundlichen Grüßen / with kind regards Rudolph Bott

Occasionally hardware changes for no reason
by Stokkenes Vidar 16 Mar '10

16 Mar '10

Hello everyone, Ever since we installed NAV, we've had a couple of switches that occasionally report a change in hardware versions for no particular reason. The output of the email is the following: <snip> This is an automatically generated message from NAV: Hardware version changed to: V09 from: 14 </snip> Does anyone know why this would happen? These come from switches with 1 year++ uptime where the IOS or hardware version hasn't been touched for half a year. We also have switches that report sudden date changes, such as the following (in Norwegian): Dette er en automatisk generert melding fra NAV: Boks switchname.domain.com (XXX.XXX.XXX.XXX) har gjennomført en coldstart: Gammel oppe siden: 1970-01-01 01:00:00 Ny oppe siden : 2010-01-15 12:16:21.863+01 Could this be a defective mainboard battery? Or is it simply NAV playing tricks with me :( Any help would be appreciated :-) Best regards, Vidar Stokkenes Helse Nord IKT

Log-engine, timestamp
by ronny.raudstein 11 Mar '10

11 Mar '10

I have installed NAV 3.5.5 on Centos 5.4, and followed the instructions by Roger Aas. Think this has been an issue in earlier versions too. The log engine seems to timestamp the syslog messages when the cisco.log file is parsed rather than when the message is generated on the device. Messages in cisco.log has correct timestamp. Look at the sample below: Cisco.log Mar 7 11:27:45 host: Mar 7 2010 11:27:47: %SEC-6-IPACCESSLOGP: list fraDMZ denied tcp x.x.x.x(2173) -> y.y.y.y(9100), 1 packet NAV - Syslog Analyzer 2010-03-07 11:27:00 host SEC-6(6)-IPACCESSLOGP 'list fraDMZ denied tcp x.x.x.x(2171) -> y.y.y.y(9100), 1 packet' Regards, Ronny Raudstein Kvinnherad Kommune

Announcement: NAV 3.5.5 released
by Morten Brekkevold 11 Mar '10

11 Mar '10

NAV 3.5.5 is now available for download at Launchpad: https://launchpad.net/nav/3.5/3.5.5 This release fixes 17 bugs in NAV 3.5. 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. At the same time I would like to apologize for lack of responses to mailing list posts the last few months. We were hoping to have NAV 3.6 ready by now, but everything has been delayed due to the fact that I was away from work for more than two months (beginning around 20th November). Happy NAVing everyone! -- Morten Brekkevold UNINETT
