NAV mac-search with Nexus and FabricPath
by Mischa Diehm 09 Apr '15

09 Apr '15

Hi, we have FP activated in our datacenter and use Cisco Nexus (5,6,7)k. I'm not sure what caused the problem but NAV can't find MAC-addresses on these devices and even on catalysts behind them anymore. I don't know what algorithm is used to figure out where a MAC-address is attached but maybe someone who knows can clarify what is needed for that to work?

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

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. (graphs are from 2 devices - one OK and the other with GAPS) Gaps are only in port metrics graphs - they are at exactly the same time on all ports on given device. 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. They were not there when I was on version 4.0b5. It happens only on cisco catalyst 4500/6500 and one type of 3560E. (I have many 3750 but, there is no problém at all) and causes inventory jobs to fail.

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.

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?

Hello, I just installed nav system from source, so I have 4.0b5 up and running. I tried so far only few Cisco boxes of these two types - Catalyst 6504 - Catalyst 4506 Even on these I'm unable to obtain software version, modules etc. It shows serial numbers and ports (but not switch ports or router ports) I tried to find out, how to troubhleshoot the proces, but nothing was usefull. Can you please advise me, what can I do to make it work? brgds Mat
