Jabber dispatcher clogs the whole alertqueue
by Ingeborg Hellemo 05 Feb '10

05 Feb '10

We have used the jabber dispatcher since december. We soon discovered that our XMPP-server implementation (Openfire) sometimes freeze. It does not crash completely, but takes forever to answer connections. When this freeze happens and NAV tries to send an alert via jabber, the whole alertqueue clogs up and no alerts gets sent at all - no email, no sms, nothing. When the jabber-daemon is restarted all the backed up alerts are sent right away. (This of course happened during the holidays and we have disabled the jabber dispatcher ever since.) Is it possible to add a timeout or something to jabber_dispatcher.py to prevent this to happen? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Observing Voice VLAN enabled ports?
by Stokkenes Vidar 05 Feb '10

05 Feb '10

Hello everyone, I am wondering if anyone have found a way to use NAV to see if a certain port is voice vlan enabled? I submitted a LP ticket about this quite some time back, but I didn't receive a reply or any feedback on it (https://bugs.launchpad.net/nav/+bug/362233) Typically we have VoIP-people dropping by our office asking "Is Port44 on switch-2.hostname.com voice enabled, and which voice vlan?" I thought maybe IP Device Info would show this in forms of another vlan, but it doesn't. It would be to great value for us atleast :-) ------------------------------------------------------ Vidar Stokkenes

Module mapping problems
by Geir Inge Jensen 02 Feb '10

02 Feb '10

Hi, I thought I should give NAV a tryout in a large service provider network. After some initial problems fetching the device information for some devices (had to remove the OSPF oid) I was finally up and running. I had to add all my device types but that was easily done (I have mostly Cisco 7600 and 7300 series devices). However, NAV has a huge problem trying to figure out which module each port belongs to (especially the 10Gb ports). Attached is a device info screen grab of one of my modules (module 5), and as you can see NAV things the module has ports from module 1, 2, 4 (and 5) as well as loopbacks and vlans. Other parts of NAV seems to get things correct (the explorer) however because of these problems they can't detect where the port connects to (link type "none"). Which sadly makes NAV useless. Is there a way I can fix this? Whenever the device info is able to pinpoint which module the port belongs to it is also able to detect the device the port connects to (including the 10Gb ports). However, that seems to be the exception and not the rule. FYI, the screen grab is from a 7609 running SRD1. Regards, Geir Inge Jensen

installation on ubuntu 9.04
by vvatikiotis＠gmail.com 07 Jan '10

07 Jan '10

Hello all, I'm trying to install nav on ubuntu 9.04 and this fails cause of 2 (only 2) dependency failures. a) python < 2.5. 9.04 has python 2.6. b) postgress = 8.1. Ubuntu has postgres 8.3 Is it necessary to pin these 2 dependency versions ? I have knowledge of python but I'd assume that 2.6 is good enough against 2.5 source code. Same goes for postgres Correct me if I'm wrong. In the mean time I'l try to force install nav. btw, seems VERY promising. thx all vassilis

Possible maintainers of a Redhat/EPEL NAV package
by Stokkenes Vidar 25 Nov '09

25 Nov '09

Hello everyone, This is probably a very delicate request, so I'll try to keep myself short. Due to our companys policies, we are trying to run everything in production on Redhat Linux servers. This is a problem when it comes to NAV, as the maintainer of the old Redhat RPM package is MIA, and no one else have really stepped forward to continue his work. I am aware of that compiling NAV from source is a viable option for someone, but considering I'm a repository maniac I would like to see Redhat on a somewhat "public" Redhat repository. We are currently undermanned and don't really have time to develop or maintain the package ourselves. However we do have resources to hire an external consulant to make the package for us. So therefor I am wondering. Lets say we hire someone to get NAV packed for Redhat Linux and submit it to EPEL, are there anyone more RPM/EPEL experienced than me who are interested in maintaining and committing new changes to the package? I've already contacted consulants at (Linpro) Redpill and gotten a time/cost estimate to develop the package. Now I just need someone volunteers to maintain the package once it's been initially set up (preferably people with commit access on EPEL) Any help or inputs would be appreciated!

Cabling and patch data removed in NAV 3.6?
by Vidar Faltinsen 13 Nov '09

13 Nov '09

nav-users, As you might know there is ongoing work on preparing a NAV 3.6beta. In 3.6 there are some changes to the database, i.e the interfaces will now relate directly to the netbox (switch or router), not to a module. We will still keep module information, but the strict mapping from interface to module is changed. This effects a number of front end (and back end) tools and we are in the process of updating it all. One system that is effected is the seed database subtool where you can add data on your twisted pair cabling and your patches from switch to jack in the wiring closets. We are seriously considering _not_ to maintain/keep this tool from 3.6. Our feeling is that _not_ many people use this part of NAV. It has never given full effect since the machine tracker does not include these data in its search results (which has been our intention of course). We also argue that by using sensible interface description naming standards you will in effect document the same data. I.e. if you set the jack number and room number as description of the switch ports that are patched to your end users/offices you have these data. The "details" link under interface in the MAC search results in machine tracker give this information (it displays the interface view of ip device info). In my opinion you should in fact do this documentation as part of your interface description, because this is useful when working directly with the switch through the CLI. Should you then double the work and do it both in the seed database patch register in addition?... Another argument is that other systems do cabling documentation more comprehensive. NAV has i.e. no support for documenting your fibre cabling. A system like Telemator (http://www.mxdata.no/) or equivalent cabling information systems do this better. Looking at integration between these systems and NAV is of course interesting. I know the University of Tromsø has done some interesting work here. Yet another mishap with the NAV patch register is that when you replace your switch with a new one, you will in the process loose your patch data for the switch and will have to do this registering from scratch again. So people out there - who is going to miss the patch and cabling part of NAV? Best regards, - Vidar

Re: VS: Radius service monitor
by Istvan Bernath 16 Okt '09

16 Okt '09

Thanks for the kind reply! Right now all our active switches are registered in NAV. There are about 130 pcs. 2510-48 and a couple of 2600-8, 2610, 2626, 2650, 2810 and 2824. The core switches are two 5406 and a single 5412. Traffic data is collected from the switches correctly. Statistics are presented fine via Cricket. Alerts, like firmware upgrade and cold start, are all noticed via Alert Manager as it should. Topology right now is totally missing, but luckily I've cached a hint of topology with a single 2824 in the middle and one 2626 one 2650 and a 2510 as the neighbors before my colleague, sorry to say, have updated to the latest firmware. The magic surely was, that the 2824 had a complete CDP and LLDP implementation in the old firmware, while all the new HP firmware has only a crippled Receive Only CDP implementation. The missing topology is rather crucial since we can be flooded by SMS and mails in case a box at the top fails. MAC information is collected, so it is possible to find a MAC number belonging to an IP number, but the MAC is not associated to any switch port, so we can not trace MAC, and use Arnold. Service monitoring is rather important for us, since our server people do need a better identification of a functioning server than a simple ping. Needless to say that a process can fail while the server still is pingable. Right now we are monitoring DNS, HTTP, IMAP, SMB, SMTP with success. The only service we are missing, for the time beeing, is the RADIUS. If I can help the developers with any tests, I would be more than happy to do it! Thanks again!

Bandwith usage not showing on some Cisco switches.
by Audun Einangen 26 Aug '09

26 Aug '09

Hi. This may be a stupid question, but I am experiencing a strange problem in NAV, where only about a third of the links on our core router shows up with any usage, the rest comes up as if there is no traffic there at all. One other switch on the network shows usage towards all other switches, but the rest of the switches on our network shows no usage whatsoever. The easiest way to see this, is when I look at the network map, and find most of the links gray, while some are green. This is a fairly new install (only a few days old,) so I may have missed some of the documentation, but I can't seem to find anything on this problem. Our goal is, among other things, to monitor for any congestions, so the map could prove useful for those purposes. Any ideas of what I might be doing wrong?

Asset tracking features in NAV

One of the features we particularly wanted from NAV is asset tracking. Am I right that these features are going to be dropped from NAV? All I really want is some way for NAV to keep track of switches in the store cupboard (both new and recycled), as well as those on the network. I don't think we are ever likely to use any features beyond that.

Email problems after upgrade
by Lars 18 Aug '09

18 Aug '09

Hi, NAV has been running on a Debian machine flawlessly for a while, but after I did a "aptitude update" and "aptitude upgrade" I ran into some problems. The updated NAV package warned me that I needed to edit in the db password manually, which I did. Firstly I had to point apache into the right directory to get the webpage to work again. It seems to work properly. It detects devices going up and down and updates statuses on the frontpage/status page and logs per device seem fine as well. So as far as I can tell the database is working as it should as well as all the background processes. Email alerts does not work though. Apparently the addresses are blacklisted according to the alertenginge.log, but I can't find any place where email addresses are blacklisted. New alert adresses also get blacklisted. From what I can see in our mailserver log, the mail alerts never get there, which is understandable since it looks like there is some setting in NAV somewhere that stop alerts from being sent. Here is an example from the log. [2009-07-27 00:48:19,368] [WARNING] [pid=5403 nav.alertengine.alertaddress.send] Not sending alert 4927 to xxxx(a)example.com as handler Email is blacklisted (Email address edited out) alertengine.err.log is empty. Email from Cron daemon works fine. I tried changing the mailserver in the alertengine.conf file, but that did not change anything. I am lost here. Anyone have any pointers?

SQL-query takes looong time
by Ingeborg Hellemo 03 Jul '09

03 Jul '09

postgresql version 8.3.7 When we use "IP Device Info" and enter the name of a SRV the resulting page takes minutes to load. Thanks to the useful Debug:-line at the bottom of the page I know this is because of this query: SELECT "cam"."camid", "cam"."netboxid", "cam"."sysname", "cam"."ifindex", "cam"."module", "cam"."port", "cam"."start_time", "cam"."end_time", "cam"."misscnt", "cam"."mac" FROM "cam" WHERE "cam"."netboxid" = 566 ORDER BY "cam"."start_time" ASC LIMIT 1 Time: 174.495 The result of this query is 0 lines since this is a SRV and not a GW/GSW. If I drop the "ASC LIMIT 1" from the query I get the answer in no time. I hope somebody with more SQL-knowledge than me can come up with a fix, since this is quite annoying. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no (Univ. of Tromsø, Norway)

cleanrrds.pl is not up to date
by Ingeborg Hellemo 03 Jul '09

03 Jul '09

NAV 3.5.4 $BINDIR/cleanrrds.pl is run nightly from crickets crontab. 1) This script has not been updated to use the new database: my $dbh = &NAV::connection('statTools', 'manage'); 2) This script also needs a version of find(1) that supports -printf. In FreeBSD we have to use gfind (no problem). gfind returns timestamps with a fractional part i.e. Thu May 28 12:38:06.0000000000 I suggest that line 117 in cleanrrds.pl is replaced with something like this: # Selects filepath,filename, time and size from the output. $line =~ m/(^\/.*)\/(.*\.rrd)\s(.*\d{2}:\d{2}:\d{2}(\.\d{10})?\s\d{4})\s(\d+)/; --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no (Univ. of Tromsø, Norway)

Wrong time zone in email alerts
by Ole Martin Bjorndalen 23 Jun '09

23 Jun '09

The new Alertengine sends email alerts where the Date header is in UTC instead of local time: From nav(a)gullars.uit.no Tue Jun 16 10:05:14 2009 Date: Tue, 16 Jun 2009 08:05:40 -0000 Alertengine uses Django to send mail, and Django sets the Date header like this: from email.Utils import formatdate, parseaddr, formataddr ... if 'date' not in header_names: msg['Date'] = formatdate() Calling formatdate() without arguments returns a date in UTC. So Django disregards its own time zone setting here. I'm not sure if it's done on purpose, but anyway a workaround in Alertengine would be to set the Date header explicitly to some localtime value, perhaps with: formatdate(localtime=True) or even better, use a value based on the time zone in the Django config. (Not sure how to do that.)

How does NAV use snmp read and write communities when both are present ?
by Gro-Anita Hillestad Vindheim 28 Mai '09

28 Mai '09

A very long subject, repeated here: How does NAV use snmp read and write communities when both are present ? Untill now, we have only used snmp read on our core boxes. We are going to deploy vlanAdmin on some core boxes, and thus we need to register snmp write communities for these. We'll use snmpview-functionality to control the permission for the snmp write community. Will this affect the NAV data collection in any way, or does all collection use snmp read even with snmp write present? (I think NAV uses snmp read, and that everything will work fine, I just have to check... ) Gro-Anita

NAV and Cisco ASA
by Stokkenes Vidar 21 Apr '09

21 Apr '09

Hello, Can someone please explain how NAV deals with Cisco ASA (or general DMZ/firewall appliances) when you have... lets say 10 virtual interfaces (sub interfaces, or VLAN interfaces)? Logically these different virtual interfaces are separated from eachother (like a general 'GW' or 'GSW' device), and I would imagine that NAV is confused about this. In my scenario, my NAV box is logically located on a Cisco ASA subinterface (a "DMZ"), but even if I add my default gateway (my vlans default GW) to NAV, it doesn't seem to poll ARP info from the Cisco ASA appliance. As I said earlier, I can imagine that NAV doesn't know how to deal with or parse the output of its ARP table as it looks like something like this: DMZ_1 192.168.1.130 0011.850f.2e01 DMZ_1 192.168.1.111 000c.29d0.772b DMZ_1 192.168.1.116 000c.2949.e0dd DMZ_1 192.168.1.153 000c.29fd.a981 DMZ_1 192.168.1.152 0013.2100.3a5b DMZ_1 192.168.1.112 000d.9d4b.039f DMZ_1 192.168.1.151 0015.1748.2291 DMZ_1 192.168.1.115 0015.1748.2025 DMZ_1 192.168.1.110 0015.1748.2639 DMZ_2 192.168.2.18 001a.a04e.6701 DMZ_2 192.168.2.13 0050.56a5.1974 DMZ_2 192.168.2.31 4a62.1283.06f1 DMZ_2 192.168.2.14 0050.56a5.4802 DMZ_2 192.168.2.30 0050.56b2.25a5 DMZ_2 192.168.2.29 0050.56b2.7c29 DMZ_2 192.168.2.200 001a.e3b1.2888 DMZ_2 192.168.2.27 0050.56b2.1531 DMZ_2 192.168.2.26 0050.56b2.5466 DMZ_2 192.168.2.10 0022.55ca.bf60 DMZ_2 192.168.2.11 0015.1720.97d6 DMZ_2 192.168.2.25 001e.c9d2.45ad DMZ_2 192.168.2.202 0022.919a.541b DMZ_2 192.168.2.20 0015.1774.6ed8 DMZ_2 192.168.2.16 0015.1715.1f3c DMZ_2 192.168.2.12 0015.1720.95c5 DMZ_2 192.168.2.17 0015.1715.1f31 DMZ_2 192.168.2.22 0011.435a.f430 DMZ_2 192.168.2.15 0015.171e.6381 DMZ_2 192.168.2.28 0050.56b2.7394 DMZ_2 192.168.2.21 0050.56b2.4c62 By all means, maybe I am mistaking - but can someone please enlighten me how to deal with these devices in NAV? Do I have to add *every* subinterface to NAV, or would it be sufficient to add whichever side is pointing towards my management network? As it appears now, NAV doesn't seem to poll ARP tables from this device (most likely because it doesn't know how to parse the table..) I also understand that even if I managed to poll ARP data from this device, I would never be able to see a box's physical (port) location as the MAC-port map table is located on another device (the core and edge switch) Thanks for any replies, and happy belated easter! ------------------------------------------------------ Vidar Stokkenes Networking Consulant Networking and telecom Department HN IKT - Tromsø Tlf: +47 76 16 61 87 / +47 77 66 99 55 Cell: +47 95 87 99 42 e-mail: vidar.stokkenes(a)hn-ikt.no  Before printing, think about the environment

Questions regarding adding devices to NAV from a different frontend.
by Stokkenes Vidar 06 Apr '09

06 Apr '09

Hello, We are currently looking into different ways to make one "authorative" device registry for servers and network equipment for our network (which is not necessarily NAV) I am simply wondering if there is any available contrib script or method to push a new Location, Room and Device into the database without using the NAV GUI? (by using a shell script, CGI, etc) That way we could use a different GUI adding new devices into NAV without depending on using the GUI. I realize that a lot of it can be done by pushing stuff directly into the PostgreSQL database, but I assume I would need some shell scripting in order to add a new device to NAV? The reason I'm wondering is because we're currently using a self scripted inventory registry for servers, and would like to know the possibility to add new devices by pushing info from this registry to the NAV database, without depending on using NAVs GUI to add new devices. I hope the question wasn't too complicated.

Problem sending SMS alerts

Hi There seem to be a bug somewhere i NAV 3.5.2 that requires the user to be member of the "NAV administrators" group to be able to receive SMS messages from NAV. A regular user with access only to specific parts of the NAV interface (including membership in the "SMS" group that gives "alert_by for sms" privileges) never recieves any SMS alerts, even if the "Alert profiles" account details informs the user that "You have permission to be alerted by SMS"...

IP device Availability shown as "N/A"
by larskulseng＠gmail.com 20 Mar '09

20 Mar '09

We're using NAV 3.5 to monitor several IP devices, including switches and access points. Most devices report an availability in the form of a percentage, likely the percentage of uptime or successful ping responses. Some of our devices, (notably all of them switches), report a "last Day" availability of "N/A". My question is, how should "N/A" be interpreted? Some switches have no known downtime and are N/A, while other test switches are purposely disconnected and also show N/A. Does N/A mean that there has been no change in the given period? A small test showed that a test switch, when left off for 24 hours, gave availability of N/A for "last Day". Once this switch was turned on, N/A turned into a percentage. Shouldn't the availability always be a percentage? Thanks! Lars

network explorer issue
by sergemueller＠gmail.com 20 Mar '09

20 Mar '09

Hi everyone, i've got some strange issues with the network explorer in nav 3.5: it shows only the root node (our coreswitch) and its vlan interfaces. The Problem might occur because the coreswitch is a h3c switch, and h3c tends to index their physical interfaces starting from .4227614 going to 4228033 (52 ports) (for the first stack member and ports of the second stack are indexed from 503316505 to 503316913 the rest looks like this: IF-MIB::ifName.14 = STRING: NULL0 IF-MIB::ifName.16 = STRING: InLoopBack0 IF-MIB::ifName.31 = STRING: Vlan-interface1 IF-MIB::ifName.2431 = STRING: Vlan-interface301 IF-MIB::ifName.4023 = STRING: Vlan-interface500 IF-MIB::ifName.4031 = STRING: Vlan-interface501 IF-MIB::ifName.4227614 = STRING: Aux1/0/0 IF-MIB::ifName.4227625 = STRING: GigabitEthernet1/0/1 the last thing shown in the netexplorer is vlan-interface 501 then the whole tree is cut of. But in the network map you can see the topology, with some switches connected to our coreswitch (uplinks detected correctly) any suggestions where to look for this problem/how to fix? thx in advance

Seaching for IP/MAC-address
by Erik Weber 23 Feb '09

23 Feb '09

I've just installed NAV locally to get the Machine Tracker, however, I can only search for ip addresses when checking the Inactive field. Results doesn't contain the MAC address either.. Any idea why this is happening? We're running cisco layer 2/3 switches (added as GSW equipment). -- Erik

NAV fails to gather serial number information
by Stokkenes Vidar 30 Jan '09

30 Jan '09

Hello, I have a rather funky problem with a few switches when adding them to NAV. Some of these swithes are *OLD* 2500 and 3500 series, and NAV will simply fail getting the serial info from the switches. Instead it will poll something like "0x0000F". I've been thinking for a long time that the serial OID was unsupported by the certain old IOS, but recently I've started seeing the same behavior on newer Cisco series such as the Catalyst 3560 series. NAV will fetch the serial info off some of these devices just perfect, while with some switches will return "Cisco 3560" as serial. I've tried added a fake serial on the few switches where I have this problem, but NAV often fails in general to poll port info etc off these devices with bogus serial info. I've done some research on two EXACT same devices (series, IOS and bootstrap version) and here is the info: Both devices show: Cisco IOS Software, C3560 Software (C3560-IPBASEK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2) Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 21-Aug-08 15:26 by nachen Image text-base: 0x00003000, data-base: 0x01600000 ROM: Bootstrap program is C3560 boot loader BOOTLDR: C3560 Boot Loader (C3560-HBOOT-M) Version 12.2(25r)SEC, RELEASE SOFTWARE (fc4) SOME-HOSTNAME-SW uptime is 1 day, 10 hours, 48 minutes System returned to ROM by power-on System image file is "flash:c3560-ipbasek9-mz.122-46.SE.bin" ... and they both show their serial info in "show version" or "show hardware". I can understand how it COULD fail on some devices for SOME reason, but why would it completely halt NAV from polling info properly? And can someone please report back if they have the same problem? (maybe it’s a bug worth troubleshooting?) Have a very nice weekend everyone, and good luck with updating! (and maybe I see some of you in Barcelona next week) :) ------------------------------------------------------ Vidar Stokkenes Networking Consulant Dep. for networking og telecommunications HN IKT - Tromsø Phone: (+47) 76 16 61 87 or (+47) 77 66 99 55 Cell: (+47) 95 87 99 42 e-mail: vidar.stokkenes(a)hn-ikt.no  Before printing, think about the environment

Undocumented dependency

Hello all, We've discovered that there is an undocumented dependency in NAV [1]. If you wish to use the service monitor's radius checker, you need to install the python module pyrad [2], AKA python-pyrad on Debian. It seems the original developer of the radius checker plugin did not report this dependency when the plugin was submitted to NAV.

Everybody's dead, I'm all alone!
by Ingeborg Hellemo 14 Jan '09

14 Jan '09

Yesterday we rebooted the switch to which our NAV-box is connected. The result was of course 1000+ alerts about our whole network going down and coming up again. The correct behaviour would of course be that NAV found out that it was _itself_ that had lost network connectivity and that the rest of the world was undetermined. 1 alert about this would suffice. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg(a)cc.uit.no (Univ. of Tromsø, Norway)

Cricket problem
by Stokkenes Vidar 16 Des '08

I suppose this topic would suit better on a cricket mailing list, but I'll give it a shot here. Ever since I tweaked the cricket version in NAV to not log INFO level to /var/log/cricket/normal.log, my cricket has completely stopped drawing graphs. When I look at my apache error file, I get the following error(s) every time I try to reload or open the page: [Fri Dec 12 09:46:13 2008] [error] [client 172.19.10.83] Name "Common::global::gEnableSearch" used only once: possible typo at /var/www/nav/cricket/index.cgi line 841., referer: https://nav.hn-ikt.no/cricket/?target=%2Frouter-interfaces%2Fgw1.domain.com… [Fri Dec 12 09:46:13 2008] [error] [client 172.19.10.83] Name "Common::global::gEnableSearch" used only once: possible typo at /var/www/nav/cricket/index.cgi line 841., referer: https://nav.hn-ikt.no/cricket/?target=%2Frouter-interfaces%2Fgw1.domain.com… [Mon Dec 15 08:07:14 2008] [error] [client 172.19.10.83] Name "Common::global::gEnableSearch" used only once: possible typo at /var/www/nav/cricket/index.cgi line 841., referer: https://nav.hn-ikt.no/cricket/?target=%2Frouter-interfaces%2Fgw1.domain.com [Mon Dec 15 08:07:14 2008] [error] [client 172.19.10.83] Name "Common::global::gEnableSearch" used only once: possible typo at /var/www/nav/cricket/index.cgi line 841., referer: https://nav.hn-ikt.no/cricket/?target=%2Frouter-interfaces%2Fgw1.domain.com… [Mon Dec 15 08:07:14 2008] [error] [client 172.19.10.83] Name "Common::global::gEnableSearch" used only once: possible typo at /var/www/nav/cricket/index.cgi line 841., referer: https://nav.hn-ikt.no/cricket/?target=%2Frouter-interfaces%2Fgw1.domain.com… When I google the error, I get some bug from 2005 that doesn't seem too relevant with my version or setup. I don't even know if the error is related with my cricket not drawing anything, but as its classified as an "error" I suppose its worth mentioning. collect-subtrees and the other navcron initiated cronjobs seems to finish without significant errors (except some interface mapping issues) and I don't think the collector itself doesn't work. I just think it for some reason can't draw the graphs onto the default graph template. So in other words, I see the graph template but no data written onto it. Can some cricket guru please tell me how I should proceed to make my cricket draw graphs again? :( Thank you in advance. ------------------------------------------------------ Vidar Stokkenes Networking Consulant Dep. for networking og telecommunications HN IKT - Tromsø Phone: (+47) 76 16 61 87 or (+47) 77 66 99 55 Cell: 95 87 99 42 e-mail: vidar.stokkenes(a)hn-ikt.no<mailto:vidar.stokkenes@hn-ikt.no> [cid:image001.png@01C95E8D.01C0C4E0] P Before printing, think about the environment

Access group SMS does not work using http-sending of SMS?
by Gro-Anita Hillestad Vindheim 16 Des '08

16 Des '08

Hi, in our test-soon-to-be-production-NAV (3.4.4), we send SMS by using the HttpGetDispatcher. From smsd.conf: dispatcher1: HttpGetDispatcher dispatcher2: GammuDispatcher My username is the only user allowed to get SMS from this test-NAV. (Alert profiles, group SMS) Still, other users keep getting SMS. As far as I know, the objective of the SMS group is to limit the number of users receiving SMS (cost-perspective). Has anyone else similar experiences? It this a known bug? Suggetions? Gro-Anita NTNU IT

Keep getting SMS alerts even though the phone number is removed from the Alert Profile
by lene.myhre＠item.ntnu.no 16 Des '08

16 Des '08

Hi, I am getting sms alerts to a phone that I have removed from the active alert profile in NAV. I did have this number there earlier, but I removed it several days ago. The new phone numbers added in the alert profiles aren't getting any alerts, this is also the case with the e-mail address I have added. It seems like NAV is using my old alert profile to send out the alerts. Is it any way to "update" this, so that NAV uses the current phone numbers in the profile instead of the old number? Regards, Lene Maria Myhre Wireless Trondheim

PHP/.htaccess error message
by Lars Marius Schjaerin 04 Des '08

04 Des '08

Hello, I have a fresh Install of Debian with a fresh install of NAV. (The machine briefly had the beta version, but I purged that package.) Installing went fine, but I had to run the database creation script manually for some reason. And I had to manually download and install a backport of python to meet the version requirements. I get this error in my apache2 error log when I try to access AlertProfiles : /var/www/nav/alertprofiles/.htaccess: Invalid command 'php_flag', perhaps misspelled or defined by a module not included in the server configuration Everything else seems to be running fine. I can add locations, rooms, devices and the log suggests all the devices I add are checked by ping. I have tried renaming the file, but that gives me a 403 instead. Commenting out the php_flag line in .htaccess gives what looks like the actual code instead of the page. Using php_value instead of php_flag gives the same message. Contents in the file are as follows : SetHandler none php_flag register_globals on The machine is running on : Apache/2.2.3 (Debian) mod_python/3.2.10 Python/2.4.4 NAV version : 3.4.4 Anyone got any pointers on what could be wrong? -- Lars Marius Schjærin Brednett AS

I can't get NAV to send alerts when IP devices is down, neither e-mail nor sms alert. I have added G01: All alerts for the profile, I am allowed to receive SMS in my account. Gammu is also installed. What am I doing wrong? I also tried adding my own filter group with different filter alerts, but nothing worked. Regards, Lene Maria Myhre Wireless Trondheim

Can't get bulk import to work
by lene.myhre＠item.ntnu.no 21 Nov '08

21 Nov '08

Hi, I have been trying adding all my IP devices with bulk import and got "green light" on all devices. But when I tried to import, I got an error message. I then tried the same prosedure again, but this time I got "red light" on all devices, even though the list was the same. I then tried adding one of the devices manually, but I got "IP already exists in database". I can't see the new IP devices in my list. Have these new IP devices been added, but are "invisible" for me in the GUI? How do I solve this? Regards, Lene Maria Myhre Wireless Trondheim

Adding wireless access points to IP devices
by lene.myhre＠item.ntnu.no 05 Nov '08

05 Nov '08

Hi, We are new to NAV and have a couple of questions regarding adding new IP devices. We are trying to add our Cisco 1242 and 1131 access points, and I can see that they are already added in the "Type" list. But we are using Lightweight AP's that does not have SNMP, so I do not have a RO community. How do I best add the access points then? Is it possible to use "WLAN" as device, or do I have to add it under "Other"? Also, adding IP devices, is it possible to have another name for them than the IP address? It's kind of confusing with over 100 IP-addresses for our access points... Regards, Lene Maria Myhre Wireless Trondheim

Possible bug in Syslog Analyzer

After installing a clean Nav on Debian with the Debian packages, i have discoverd that the table with origins only display ip-adresses and not the hostname.

Issues with servicemon
by Stokkenes Vidar 08 Okt '08

08 Okt '08

Hello, Ever since I migrated to a seperate PostgreSQL server, I've had various issues with dying NAV processes/daemons. The most common one is this error, appearing in servicemon.log after enabling DEBUG in the nav.conf file: FROM serviceproperty order BY serviceid [2008-10-08 12:38:58] servicemon.py:__init__:61 [Notice] Setting checkinterval=60 [2008-10-08 12:38:58] servicemon.py:__init__:63 [Notice] Reading database config [2008-10-08 12:38:58] servicemon.py:__init__:64 [Notice] Setting up runqueue [2008-10-08 12:38:58] RunQueue.py:__init__:98 [Notice] Setting maxthreads=20 [2008-10-08 12:38:58] RunQueue.py:__init__:100 [Notice] Setting maxRunCount=50 [2008-10-08 12:38:58] db.py:cursor:85 [Critical] Could not get cursor.

The PostgreSQL server itself is a Quad core CPU box with 8GB of ram, and should not be overloaded in any way. Load is ~0.10 at all times.

Removing HP SwitchStack support from NAV
by Morten Brekkevold 17 Sep '08

17 Sep '08

Hi everyone, for quite some time we've been aware of many fundamental problems with the way support for HP SwitchStacks has been implemented in NAV. HP SwitchStack support was implemented in NAV 3.0 at NTNU, whose HP equipment consisted solely of HP SwitchStacks at that time. The result is code which is heavily biased towards SwitchStacks, to the point that NAV thinks HP devices are always SwitchStacks, no matter what. While we have been pondering alternative ways to model HP SwitchStacks (and consequently, Cisco switch clusters, which are basically the same thing), NTNU has entirely stopped using SwitchStacks. Today, they're experiencing bad side effects of the existing HP-related code in NAV. They're using some HP devices for routing, which NAV cannot handle at all (because of said "HP=SwitchStack only" view). No router ports are collected for these routers. Also, they seem to have many errors in topology information when HP devices are involved. Realizing that NTNU have stopped using SwitchStacks, we also do not know of anyone else who does, so now we are considering dropping support for SwitchStacks entirely from NAV. This way, the existing NAV code can treat HP devices like everything else. Preliminary tests of these changes at NTNU show promising results. So my question to the users of NAV is: Does anyone actually use virtually stacked HP switches? Will anyone miss support for this if removed from NAV? If there is no feedback on this issue, we will likely remove this support starting from NAV 3.5. -- mvh Morten Brekkevold UNINETT

Feature request hidden in Launchpad?
by Stokkenes Vidar 05 Sep '08

05 Sep '08

Hello, I might be the one not searching good enough, but I couldn't really find anywhere to put a feature request on Launchpad. As I've seen quite a few suggestions on stuff on this list, I might as well give it a shot here. One of many NAV features we've found handy, is the Module State warning feature. What I really don't understand, is why NAV haven't built in a PSU State warning system. There are numerous of MIBs under the CISCO-ENVMON-MIB <http://tools.cisco.com/Support/SNMP/do/BrowseMIB.do?local=en&step=2&mibName…> tree for this task. A Cisco specific MIB for the general PSU status would be "1.3.6.1.4.1.9.9.13.1.5.1", and would give you the following result on: Cisco 65XX series: SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1 = STRING: "Power Supply 1, WS-CAC-2500W" SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2 = STRING: "Power Supply 2, WS-CAC-2500W" SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.2 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.1 = INTEGER: 2 SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.2 = INTEGER: 2 Cisco 35XX series: SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1003 = STRING: "Sw1, PS1 Normal, RPS NotExist" SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1003 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.1003 = INTEGER: 2 Cisco 45XX series: SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1 = STRING: "Power Supply 1" SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2 = STRING: "Power Supply 2" SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.2 = INTEGER: 1 SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.1 = INTEGER: 2 SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.2 = INTEGER: 2 The status integers for the power supply MIB are pretty much alike the Module State warning integers, so implementing such a feature wouldn't be a big problem. And the graphical interface/warning would look pretty much the same as the Module State thing when browsing a device, or as a Power Supply failure on the Status page.. I don't know about others, but I like to get a warning when my power equipment fails, or we're having a power failure :) Any thoughts? ------------------------------------------------------ Vidar Stokkenes Konsulent Nettverk Seksjon for nettverk og telekom HN IKT - Tromsø Tlf: 76 16 61 87 / 77 66 99 55 Mobil: 95 87 99 42 e-post: vidar.stokkenes(a)hn-ikt.no<mailto:vidar.stokkenes@hn-ikt.no> [cid:image001.png@01C90F3D.BA283A30]

It's output is not all terribly useful. OK, so a suggestion is that in nav.conf you currently have (for example): # The e-mail address of the NAV system administrator. All cron error # messages will be sent to this address. ADMIN_MAIL=systjc(a)ecs.soton.ac.uk I suggest you add another option CRON_MAIL=.... so you can still have an admin contact on the NAV system/web view, but direct cron stuff easily to nowhere.

We have only been running for a month or so on 15 stacks, so it was actually very quick :) manage=> UPDATE arp SET sysname=n.sysname FROM netbox n WHERE n.netboxid=arp.netboxid; UPDATE 12824 manage=> UPDATE cam SET sysname=n.sysname FROM netbox n WHERE n.netboxid=cam.netboxid; UPDATE 68724 As far as we can see, all the old historic IP-names are now updated to names, which has added consistency to the searches and machine tracker.

I agree - the above fix is a useful tip for when a new site like us doesn't have reverse DNS capability in place before firing up NAV, to 'clean' the data. -- Tim

I suspect a few people will make the smae 'mistake' that we did, to enter systems by name, but these are converted to IP-names because a reverse lookup is not available. I think this warning was in the small print of the docs, but we were too excited during install and missed it. We'll check out the new bugtracker very soon! Regarding the database change offer, we'd be up for trying it if you can provide the magic incantation :) The switch stacks are: 10.78.64.61 b86-l1-cat1 10.78.64.63 b59-l2-cat1 10.78.64.64 b59-l3-cat1 10.78.64.65 b59-l4-cat1 10.78.64.66 b1-l1-cat1 10.78.64.67 b16-l2-cat1 10.78.64.68 b1-l1-cat2 10.78.64.69 b32-l3-cat1 10.78.64.70 b32-l3-cat2 10.78.64.71 b32-l4-cat1 10.78.64.72 b32-l4-cat2 10.78.64.75 b59-l3-cat2 10.78.64.76 b53-l2-cat1 10.78.64.77 b53-l3-cat1 10.78.64.78 b53-l4-cat1 10.78.64.79 b53-l4-cat2 Some were added after we arranged reverse DNS to work (added a local /etc/hosts entry for convenience) so may not have the problem, but most of them do.

That would account for the problem you're having. Thanks for the explanation. What then is the recommended way to suppress errors related to this OID? NAV kindly generates email alerts for errors when querying devices, we just have a few too many related to this OID :) Is there a recommended way to configure NAV to not poll our 3750 stacks for temp data? I see there are config files under Cricket for generic routers and switches with this OID, i.e.: /etc/nav/cricket-config/routers/Defaults /etc/nav/cricket-config/switches/Defaults And also some reference in /etc/nav/cricketoids.txt /etc/nav/cricket-config/config.db It looks like Cricket generates the Defaults file and the config.db each night, while cricketoids.txt is static, but it's not clear to us where those nightly builds are driven from (i.e. where we could remove/suppress the temp entry). It sounds like even using snmpwalk to grab the current indexed value wouldn't help as it is liable to change. The temperature queries work just fine for our Cisco 6509, so ideally we wouldn't want to generically remove temp readings for everything. A week ago I knew far less about OIDs and I think I was better for it :) Thanks, Tim

Device names query
by Tim Chown 28 Aug '08

28 Aug '08

Hello again :) Hopefully a quicker query. When we first set up NAV, our networked devices, with their Net10 addresses(*), did not resolve to names, so our database populated with device names that were IP addresses. We since ensured the names resolved, and NAV figured this out, with new data being linked to the devices by name, rather than the 'IP name'. The problem seems to be though that the 'IP name' causes some problems when searching on data, e.g. a search based on the new name won't match against the old 'IP name'. Is there a neat way to fix this? e.g. perhaps to simply remove all records for the 'IP name' devices? Advice welcomed. -- Tim (*) historic reasons :)

Question on SNMP/tempInlet

Hi, I noticed our cricket cron is generating errors on one SNMP OID, i.e. [14-Aug-2008 14:40:01 ] Retrieved data for b1-l1-cat1 (): U,U,U,U,U,U,U,U [14-Aug-2008 14:40:01 ] Some data is missing for b1-l1-cat1 (). [14-Aug-2008 14:40:01*] Received SNMP response with error code noSuchName. OID: 1.3.6.1.4.1.9.9.13.1.3.1.3.1 Error and the lines leading up to it: [14-Aug-2008 14:40:01 ] Some data is missing for b1-l1-cat1 (). [14-Aug-2008 14:40:01*] Received SNMP response with error code noSuchName. OID: 1.3.6.1.4.1.9.9.13.1.3.1.3.1 And yet if I look at the SNMP OID support listed for the device as reported by NAV I see: b1-l1-cat1 tempInlet 1.3.6.1.4.1.9.9.13.1.3.1.3.1 CISCO-ENVMON-MIB ciscoEnvMonTemperatureStatusValue 21600 which implies the OID is supported, and is the device inlet temperature. Is there some additional IOS config required to make this particular data available to Cricket? Being new to OIDs, I'm confused as to why it seems to be available according to NAV, yet Cricket's getting an error. Thanks :) -- Tim

Unexpected link into ipdevinfo beta code?
by Tim Chown 28 Aug '08

28 Aug '08

Hi, One of our admins spotted this, not sure if a bug or feature, so not submitted it (yet) to the bug tracker. If you drill down, as an Authenticated User, into Machine Tracker / MAC Search / MAC Search results and then click the (details) link for an interface you are jumped into the /ipdevinfo code, and taken out of the main browse/report code. Since the default permissions for an Authenticated User does not include ipdevinfo, the user gets a permission denied :( I think the (details) link should take you to a link like /browse/b59-l2-cat1/module3/port1846/ rather than one like /ipdevinfo/b59-l2-cat1/module=3/swport=GigabitEthernet3/0/44/ but I assume this has been done in part to test the ipdevinfo beta code? Both pages seems to serve a similar function, one the old way, one (I assume) the new way under development? (The ipdevinfo page doesn't have the Cricket links in place yet) The problem is that Authenticated Users hit this permissions issue, but if we try to add |ipdevinfo| into the web_access permissions, it doesn't seem to resolve the permissions problem. Is that link to the newer stuff intended? If so, how should we correct the permissions problem? Thanks :) -- Tim

Hi all NAVers! Our new bugtracker is located at http://bugs.launchpad.net/nav All of the bugs that were reported on Sourceforge was imported, so all the data should be there. To simplefy bug-reporting for developers and other console-junkies, the nav-tip[0] now has a small tool called nav_bug.py in the contrib folder. Add this tool to your path and run nav_bug.py --help for more info about how to use the tool.

Questions on prefixes and traffic maps
by Tim Chown 20 Aug '08

20 Aug '08

Hi NAVers, We've just installed NAV on a Debian4 r3 system for our department network that has a core Cisco 6509 and a number of satellite 3750 stacks and Cisco wireless APs. At present our 3750 stacks are switching only, and thus in NAV we entered them as SW devices (Layer 2, many vlans). So far in NAV we have enabled monitoring of our 3750 stacks, but not yet the core 6509, so we only have layer 2 info/configs. We're getting data now for our switch port use, and cricket showing info on packet rates through the ports. When we do add the 6509, how should we enter the prefix/scope information? I'm a little confused as to the meaning of static/reserved/scope for the 'Add prefix' option in the Edit Database. We have maybe 25 vlans and subnets, and I assume we need to add them all here. I assume we use 'scope' for devices we manage? I notice we cannot add vlans directly; I assume this is implied from the vlan information added in the prefixes? Second main question is on the traffic maps. It seems at first glance that these show traffic between router interfaces. Is it possible to have the traffic map show loads between trunk ports that connect switch stacks? That would be very useful for us if it could be configured. Thanks for any comments or suggestions/tips! -- Tim

Announcement: NAV 3.4.1 released
by Morten Brekkevold 03 Aug '08

03 Aug '08

NAV 3.4.1 is now available for download at SourceForge: http://sourceforge.net/projects/nav/ This is a bugfix release, the changelog is attached to this message. Binary packages for Debian will be available soon. The Debian package is maintained by Morten Werner Forsbring, on commission from UNINETT. We are currently working on migrating NAV from SourceForge.net to Launchpad.net; downloads and issue trackers will be available there once the migration is complete (a separate announcement will be made). We are also working on complete rewrites of AlertEngine and AlertProfiles in Python, thereby ridding NAV entirely of PHP, and almost entirely of Perl. In the process we will also solve some of the basic problems that have plagued alert profiles and alert dispatching for a while. We are hoping to introduce these rewrites in NAV 3.5, scheduled for this fall. Happy NAVing everyone! -- mvh Morten Brekkevold UNINETT

Problem with Network explorer after upgrading to 3.4/3.4.2 and an issue with c6509-E
by Rikard Stemland Skjelsvik 01 Aug '08

01 Aug '08

Dear all, I have a small issue with Nav after upgrading to 3.4 When i click on the link to Network explorer, i get the following error: HTTP Status 404 - /navAdmin/servlet/navAdmin type Status report message /navAdmin/servlet/navAdmin description The requested resource (/navAdmin/servlet/navAdmin) is not available. Apache Tomcat/5.5 The catalog /var/www/nav/navAdmin only includes .htaccess and an index file that is zero bytes. I am running Debian and i upgraded from a previous version(where network explorer worked) with the apt-get dist-upgrade command. My google-fu came up with a previous poster where Morten Brekkevold replied: NAV contains two Java servlets, vPServer.war and navAdmin.war . These are usually installed in the apache/webapps/ directory, and should be symlinked into Tomcat's webapps directory (wherever your Tomcat installation may be, you don't mention which distro you are using). The catalog /var/www/nav/vPServer, as /var/www/nav/navAdmin, includes only .htaccess and index. A find reveals that both vPServer.war and navAdmin.war is installed in /var/lib/tomcat5.5/webapps/ I would apreciate any help or pointers that could help me solve this problem. As a side note: When adding a Cisco 6509 running s72033_rp-ADVIPSERVICESK9_WAN-M), Version 12.2(33)SXH1, RELEASE SOFTWARE (fc3) to NAV, the cpu on the 6500 went through the roof. This could be a bug, though, i have seen CiscoWorks doing the same before. Any ideas? Is there a way to "nice" NAV on some types of equipment? Regards, Rikard

questions on MetaNAV about ipv6
by yongkai Jiang 01 Aug '08

01 Aug '08

hi all, I am writing this letter to ask some questions about ipv6 support on MetaNAV. We are investigating into MetaNAV3.4 to manage ipv6 networks. In MetaNAV3.4.0 release note, it says that the system supports ipv6 now. I am a new comer to MetaNAV and know little about SNMP and ipv6 at the moment. So I wonder what does it means by supporting ipv6? Does it means that it has full support on it? eg, can metanav discover an ipv6 device and query related information from it(cpu,load, etc.)? Does it auto-discover the topology in an ipv6 vlan? Can it deal with ipv6 addresses? ... Thanks in advance! Best regards! Sincerely, Richard July 30, 2008

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

21 Jul '08

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

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

25 Jun '08

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

Well, upon reading the truss output of "nav start getDeviceData", it seems that the "su" command is the one that hangs after the chdir command. Can you successfully execute "su - navcron" as root?

I think the > inherent difference may help us to understand what is happening and why the > failure. Or at least may help me to locate more pertinent data. There's no difference, really. The nav command is a convenience tool to do all the starting and stopping in one go (plus the added crontab manipulation). It still calls the etc/init.d scripts in the end. Are you running both commands as root? >> Besides, you say that "nav start alertengine" seems to stall, and this >> command will not modify the crontab, since alertengine isn't a cronjob >> but a daemon.

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

Services

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

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

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

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

09 Apr '08

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

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

28 Mar '08

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

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

PythonHandler common error SLES 10

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

26 Mar '08

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

Hi Keith, Are you using PHP5? The AlertProfiles tool sometimes outputs a few strange warnings/error messages under PHP5, but these do not seem to be detrimental to AlertProfiles' functioning. Unfortunately, there are no PHP-savvy/friendly developers currently working on NAV, so we've yet to find the time to figure out how to quench these messages.

problem with installing nav
by yonat2＠post.tau.ac.il 29 Nov '07

29 Nov '07

Hello, I'm working on linux Debian and i have little permissions. I'm trying to install NAV using your guide of "getting started". When I try to run "nav start" I get that the following services are down: eventengine getDeviceData snmptrapd. I recieve the following error msg: "Failed: eventengine getDeviceData snmptrapd Errors: tmp (Command failed: 32256)" When trying to run "etc/init.d/eventengine start" I recieve the following error msg: " createConnection ClassNotFoundExecption error: org.postgresql.Driver Error, could not connect to database! Failed". When trying to run "etc/init.d/snmptrapd start" I recieve the following error msg: "psycopg.ProgrammingError: ERROR: relation "subsystem" does not exist INSERT INTO subsystem (SELECT 'snmptrapd', '' WHERE NOT EXISTS (SELECT * FROM subsystem WHERE name = 'snmptrapd')) Failed". What should I do? Thank you.

That object contains both source and agent, where source is the ip-source address and agent is the agent-address. However, if you are referring to the linkupdown-traphandler, I agree that the use of trap source to locate the device that triggered the event is wrong.

snmptrapd does not follow specifications
by Ingeborg.Hellemo＠cc.uit.no 20 Nov '07

20 Nov '07

When snmptrapd receives a snmptrap it is _not_ supposed to use the IP-source address of the packet as the sender of the trap, but look inside the snmp-packet (agent-addr in SNMPv1) to see who the trap really comes from. There are several RFCs and papers about this (and we have mentioned it earlier). Please? --Ingeborg -- Ingeborg ?strem Hellemo -- ingeborg(a)cc.uit.no (Univ. of Troms?, Norway)

Come to think of it, I believe the code for IPv6 is still in my branch and needs to be merged with trunk. Meaning that before anyone do so, you either have to wait for someone to do it, or do it yourself. Only problem is I believe the note which said when the last merge was done is gone. Hurray for SVN.

I took a look at servicetable.py on po, and it doesn't match servicetable.py from the current trunk or NAV 3.3.

AlertEngine - delayed alerts, something is not right
by Ingeborg.Hellemo＠cc.uit.no 31 Okt '07

31 Okt '07

(My mission this week is to keep you occupied with new bugs) I have made a nightly profile which is supposed to send alerts immediately via email and delayed (Daily queue) to my phone. Something is happening with queuing/deleting alerts which makes me receive two emails and I am not sure if I would have received any sms in the morning. (Today I wasn't supposed to because all downs were canceled by ups). >From alertengine.log: Wed Oct 31 04:08:57 2007 alertEngine NewAlerts-7-collectInfo: found 1 new alerts Wed Oct 31 04:08:57 2007 alertEngine QueuedAlerts-7-collectInfo: collecting info about queued alerts Wed Oct 31 04:08:57 2007 alertEngine User-7-checkAlertQueue: borge(1000);

snmptrapd with ImportError

Thanks, I had a poke, and now I know what the problem is. Your immediate fix is to do the following as root: touch /usr/local/nav/lib/python/nav/snmptrapd/__init__.py which will make Python actually recognize nav.snmptrapd as a proper Python package. The reason I was unable to reproduce the problem on my end was that I assumed this occurred when you started the daemon, but it seems it actually occurs every time a trap is received (and I had nothing configured to send traps to my daemon). The problem being that snmptrapd imports the handler modules every time it receives a trap, and not just once at the start of the process (which I think it should). I've filed this as two separate bugs in the tracker: 1. http://sourceforge.net/tracker/index.php?func=detail&aid=1822650&group_id=1… 2. http://sourceforge.net/tracker/index.php?func=detail&aid=1822651&group_id=1… -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Tue Oct 30 11:07:04 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Tue Oct 30 11:07:07 2007 Subject: [Nav-users] Nagios+lampp In-Reply-To: <Pine.LNX.4.64.0710261910340.3828(a)tyholt.uninett.no> (Vidar Faltinsen's message of "Fri, 26 Oct 2007 19:11:39 +0200 (CEST)") References: <20071026092109.wzj2jfan2c08084s(a)charlie.vbnet.com.br> <Pine.LNX.4.64.0710261910340.3828(a)tyholt.uninett.no> Message-ID: <yylabq0x6ev.fsf(a)voldsminde.uninett.no> Vidar Faltinsen <vidar.faltinsen(a)uninett.no> writes: > On Fri, 26 Oct 2007, marcos.sandrini(a)embryo.com.br wrote: > >> Bom dia! > > Bom dia, to you, too!

I had a chat with Arne, one of the original developers of the alert system (since I haven't touched PHP in many years now), as we tried to upgrade to PHP5. He suggested that these errors had been present all along, but that previous php versions suppressed them by default. I think he based this on the fact that whatever error messages Alert Profiles spat at us under PHP5, anything we did in the Alert Profiles interface would still work as before.

Ranked Statistics: 12334963.32 percent
by Ingeborg.Hellemo＠cc.uit.no 30 Okt '07

30 Okt '07

12334963.32 percent is a nice number if you talk about increase in wages, but not if you talk about mortgage rates or CPU load. Something is wrong with our "Ranked Statistics". Top 20 CPU Routers show 6 boxes with impossible values, but if i click on the "Target"-link, the graph shows normal values (but not high enough to put it into Top 20). The rest of the boxes show normal values. The other views shows just as erroneous behaviour. Is this a result of us using RRDtool version 1.2.23? --Ingeborg -- Ingeborg ?strem Hellemo -- ingeborg(a)cc.uit.no (Univ. of Troms?, Norway)

Pilot installation and some problems
by rskjels＠pogostick.net 16 Okt '07

Dear all, I have installed Network Administration Visualized 3.3.0 on Debian Etch. I have installed NAV through aptitude. I'm very impressed with the amount of work and thought that have gone into this software package. However, i do have several problems. I can not see any informastion in the section called "Port View" when i click on a device in Home > Report > Devices in Operation Could this be some snmpproblem? I installed net-snmp and could do a snmpwalk against the device. Also serveral devices report Availability like this one: Availability -4.1e+180% -5.1e+175% -3.8e+166% (day / week / month) Could this be snmpversion troubles? When i try click on the Traffic Map, all i get is a new page showing a java aplet that just show the java logo. I have tried this with both firefox and IE. The only way to exit is to kill the browser process. Could this be a java version problem. getDeviceData.log is zero size. /var/log/nav/getDeviceData/getDeviceData-stdout.log is also zero. In /var/log/nav/getDeviceData/getDeviceData-stderr.log contains: java.lang.NullPointerException at snmp.SNMPSequence.setValue(Unknown Source) at snmp.SNMPVariablePair.<init>(Unknown Source) at snmp.SNMPv1CommunicationInterface.getNextMIBEntry(Unknown Source) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAllJavaSnmp(SimpleSnmp.java:665) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:640) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:616) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:598) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:522) at OidTester.doTest(OidTester.java:115) at OidTester.oidTest(OidTester.java:44) at QueryNetbox.run(QueryNetbox.java:724) java.lang.NullPointerException at snmp.SNMPSequence.setValue(Unknown Source) at snmp.SNMPVariablePair.<init>(Unknown Source) at snmp.SNMPv1CommunicationInterface.getMIBEntry(Unknown Source) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAllJavaSnmp(SimpleSnmp.java:690) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:640) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getAll(SimpleSnmp.java:616) at no.ntnu.nav.SimpleSnmp.SimpleSnmp.getNext(SimpleSnmp.java:303) at no.ntnu.nav.getDeviceData.deviceplugins.MibIISw.MibIISw.processMibII(MibIISw.java:308) at no.ntnu.nav.getDeviceData.deviceplugins.MibIISw.MibIISw.handleDevice(MibIISw.java:144) at QueryNetbox.run(QueryNetbox.java:787) Could this be related to the missing port view section?

Hi Nestor, Either your Tomcat servlet container is not running, or it is listening to the wrong port (which I doubt, unless you've changed your Tomcat config). Check the tomcat status using "invoke-rc.d tomcat5.5 status". If it's not running, you can start it using "invoke-rc.d tomcat5.5 start" (as root, of course). -- mvh Morten Brekkevold UNINETT

Still looks fishy to me, when the java command appears not to understand the regular arguments. There's a lot of things we could check here: * What is your JAVA_HOME environment variable set to? * Can you confirm this is the value set for the cronjob? * What is JAVA_HOME set to in nav.conf? * Are there any other JVMs installed? ("rpm -qa | grep java" and "update-alternatives --display java") * What Java VM is running getDeviceData? (ps axuwww|grep getDeviceData) Is networkDiscovery the only NAV process which gives you this problem?

The University of Troms? is still alive and kicking, but we have been somewhat busy with other issues with NAV 3.3.0 We have now began to go through the service-monitor in ver 3.3.0 and already found a couple of issues.

Also, servicemon.conf can be used to configure the debug level of this log. I'm looking at the SmbChecker plugin now, and it doesn't look good to me, though. It parses the output of the following command to verify the status of a samba server: /usr/bin/smbclient -L %s -p %i %s 2>/dev/null %s is the server IP address (or host name configured when adding the service handler), %i is the configured port (139). If you've entered a username and password in the service handler config, %s will be "-U username%password", and if you configured a workgroup, it will also contain "-W workgroup". This also means that your smbclient program must be located in /usr/bin/smbclient , since this is hard coded into the plugin :-( If your smbclient is not located in /usr/bin, or your version of smbclient does not support the above mentioned arguments, then I guess you will have trouble with this plugin. -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Fri Oct 12 11:17:29 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Fri Oct 12 10:18:15 2007 Subject: [Nav-users] Traffic Map will not display In-Reply-To: <3987.207.61.90.34.1191436754.squirrel(a)webmail.niagara.com> References: <3987.207.61.90.34.1191436754.squirrel(a)webmail.niagara.com> Message-ID: <470F2D99.2080109(a)uninett.no> rkillick(a)niagara.com wrote, On 03-10-2007 20:39: > The Traffic Map will not display and simply shows an empty box where the > map should be, and a lone remark in the status bar at the bottom left > "Applet vlanPlot notinted".

Hi Bob, My first question is: Does the Network Explorer work for you? When the traffic map applet has problems, you should enable your Java Console and load the applet again, to see what is logged in the console. I can't give you an exact account of how to enable the Java Console, as this depends on both your OS and browser, and I don't know which you're using. If you can't figure it out by yourself, tell me which os/browser you are using, and I'll help you. Typical problems with the traffic map are: * The tomcat servlet container isn't running, so the traffic map cannot fetch it's data. * The apache server is accessed under a different host name than what is configured in the ServerName apache config option. The traffic map will attempt to fetch its data from a an URL with the ServerName in the host part, but the java applet security model will not allow applets to access anything but the same hostname the applet was loaded from. -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Fri Oct 12 11:23:24 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Fri Oct 12 10:23:29 2007 Subject: [Nav-users] Could not connect to servlet In-Reply-To: <58B7A531794E6A49B3BAD57E333225440249A320(a)engexc11.archstonesmith.com> References: <58B7A531794E6A49B3BAD57E333225440249A320(a)engexc11.archstonesmith.com> Message-ID: <470F2EFC.1090408(a)uninett.no> Pabon, Nestor wrote, On 08-10-2007 19:09: > When attempting selecting the Network Explorer I get the following: [snip] > error: (111, 'Connection refused') > This is a packaged installation of NAV 3.2.2. on a Debian Etch 4.0. Hi Nestor, Either your Tomcat servlet container is not running, or it is listening to the wrong port (which I doubt, unless you've changed your Tomcat config). Check the tomcat status using "invoke-rc.d tomcat5.5 status". If it's not running, you can start it using "invoke-rc.d tomcat5.5 start" (as root, of course). -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Fri Oct 12 11:31:34 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Fri Oct 12 10:31:37 2007 Subject: [Nav-users] Java error In-Reply-To: <1191965071.15629.17.camel(a)thales.iwu.edu> References: <1191965071.15629.17.camel(a)thales.iwu.edu> Message-ID: <470F30E6.1010401(a)uninett.no> Pat Riehecky wrote, On 09-10-2007 23:24: > I am getting the following error in the networkDiscovery log: > > Warning: -Xmx256m not understood.

Yes, PostgreSQL has always interpreted a backslash as an escape character, so these INSERT statements escape the backslash that we want to store in the database using a backslash, i.e. \\ to store one \ . But it seems PostgreSQL is going to change this behaviour in the future, so I guess they added a warning about in in 8.2. Google yielded this: http://www.mydatabasesupport.com/forums/1004812-post2.html This is probably going to be a problem for many software packages, including NAV, since most database drivers tend to escape special characters in strings using backslashes. I'm sure you'll see more of these warnings in the logs while NAV is running. If you want to get rid of them, I suggest adding "escape_string_warning = off" to your postgresql.conf, as one of the suggested solutions in the above URL reads. -- mvh Morten Brekkevold UNINETT >From prieheck at iwu.edu Fri Oct 12 10:29:09 2007 From: prieheck at iwu.edu (Pat Riehecky) Date: Fri Oct 12 16:29:14 2007 Subject: [Nav-users] Java error In-Reply-To: <470F30E6.1010401(a)uninett.no> References: <1191965071.15629.17.camel(a)thales.iwu.edu> <470F30E6.1010401(a)uninett.no> Message-ID: <1192199349.10913.32.camel(a)thales.iwu.edu> Hello, I followed the instructions at http://metanav.uninett.no/InstallingOnRHEL4 [root@stats networkDiscovery]# which java /usr/bin/java [root@stats networkDiscovery]# `which java` -version java version "1.5.0_13" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05) Java HotSpot(TM) Client VM (build 1.5.0_13-b05, mixed mode) [root@stats networkDiscovery]# rpm -qa |grep sun java-1.5.0-sun-1.5.0.13-1jpp.1.el4 java-1.5.0-sun-jdbc-1.5.0.13-1jpp.1.el4 # ls -l `which java` lrwxrwxrwx 1 root root 22 Oct 2 03:32 /usr/bin/java -> /etc/alternatives/java [root@stats bin]# ls -l /etc/alternatives/java lrwxrwxrwx 1 root root 35 Oct 12 09:13 /etc/alternatives/java -> /usr/lib/jvm/jre-1.5.0-sun/bin/java I also have the slightly older java recommended by the instructions, but I get the same error either way.

postgres and "nonstandard use of \\"
by Ingeborg.Hellemo＠cc.uit.no 10 Okt '07

10 Okt '07

My postgres 8.2 is whining about "WARNING: nonstandard use of \\ in a string literal at character NN" "HINT: Use the escape string syntax for backslashes, e.g., E'\\'." I think I have located the source of the warnings to be these lines in /usr/local/nav/doc/sql/navprofiles.sql (NAV 3.3.0) INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/toolbox\\b'); INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/index(.py)?/(index|login|logout|userinfo|passwd)\\b'); INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/messages/(active|historic|planned|view|rss)\\b'); INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/maintenance/(calendar|active|historic|planned|view)\\b'); INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/vlanPlot\\b'); INSERT INTO AccountGroupPrivilege (accountgroupid, privilegeid, target) VALUES (2, 2, '^/vPServer/servlet/vPServer\\b'); Are the lines supposed to look like this? --Ingeborg -- Ingeborg ?strem Hellemo -- ingeborg(a)cc.uit.no (Univ. of Troms?, Norway)

NAV 3.3.0 RC1 + Unsupported SNMP protocol version

No, that won't be necessary. I've just tested it some more and found that this only happens if no response is received, not even an ICMP port-not-reachable message. If the NAV server receives such an ICMP message from the target or the router, it will instead display "Connection refused". I guess this indicates that the SNMP UDP request packet is lost on the way to the target, either dropped by some firewall or the box itself, or the return packet is dropped in a similar fashion. I will add an issue for this in the bugtracker, but for now, the error message can be intepreted as a timeout error. -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Fri Oct 5 12:33:01 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Fri Oct 5 11:33:52 2007 Subject: [Nav-users] Announcement: NAV 3.3.0 RC1 released In-Reply-To: <4700E4AD.3060709(a)gmail.com> References: <46EFCB84.70504(a)uninett.no> <46F8AC23.8090409(a)gmail.com> <4700B683.4050103(a)uninett.no> <4700E4AD.3060709(a)gmail.com> Message-ID: <470604CD.9050004(a)uninett.no> Erik Weber wrote, On 01-10-2007 14:14: >> I suspect you are thinking of process monitoring through SNMP?

Traffic Map will not display
by rkillick＠niagara.com 03 Okt '07

03 Okt '07

I have recently installed Nav 3.2.2 onto a CentOS 4.5 workstation using the available installation notes. I have been able to seed the database (6 xGSW + 43 x SW) and have tested most of the tool box tools without much problem with the exception of the Traffic Map. The Traffic Map will not display and simply shows an empty box where the map should be, and a lone remark in the status bar at the bottom left "Applet vlanPlot notinted". Note: The "IP address scope - graphical view" works fine. I have placed 6 x GSW (C3750s) into the '_Top' map container. Any ideas as to where to begin looking for the problem would be appreciated.

The two methods your compiler is unable to find were added to SimpleSnmp.java after NAV 3.2.2, and are present in the 3.3 release candidate. It's as if you are compiling a new version of getDeviceData against an old version of SimpleSnmp. Of course, when you replace OidTester.java with a version as old as the SimpleSnmp.java without the two new symbols, you will have success in compiling, but you will experience other problems during runtime (such as the Drexel SNMP memory leak / inifinite loop problem).

Due to limited resources, the core NAV developer team is not focusing on new service monitoring functionality, but on the core network monitoring functionality.

Debian Etch with the latest > package from Werner. A quick look at the code reveals a bizarre procedure; EditDB attempts to find out which SNMP version the box supports. It first attempts version 2c, if this times out it tries version 1, if this also times out it claims the SNMP version is 0. Apparently this value is used in later requests, which, of course, fails miserably. So, to make it short: It seems that what really happens when you get this message is that SNMP communication with the box timed out.

Apparently there are two very similar libraries in existance: One is distributed alongside rrdtool itself, and one is available at http://sourceforge.net/projects/py-rrdtool . The one currently in use by us on our dev server is the python-rrd library that comes with rrdtool itself; in Debian this package is called python-rrd. The package also follows the same version numbering scheme as rrdtool, which means that the latest version of it is >= 1.2. Unless Suse 10.2 prepackages this alongside its regular rrdtool package, you'll need to get hold of the rrdtool source code instead. This would also be the best way to make sure the python library version matches the rrdtool library version. > 2 and 3 pping and servicemon failed to start, I tried a nav start pping > servicemon a couple of time, also a start separate. > but they whon't start.

The DEBUG_LEVEL in nav.conf only sets debug levels for the Java subsystems (i.e. getDeviceData, eventEngine, getBoksMacs, networkDiscovery). The pping and servicemon processes have their own debug level settings in their respective config files.

You don't specify which version of NAV you are running, but I'm sure you're not using anything earlier than 3.1.1. We fixed a long standing problem with missing link load in the Traffic Map in that version, but you may be experiencing a different problem. The Traffic Map applet requests its data from the vPServer servlet running in the Tomcat container; the vPServer component calls the vprrd.py script to retrieve the actual RRD data, and something might have gone wrong during the calling of this script. I have to go now, but I will get back to you on this later, when I figure out whether there are any logs you can check to find the problem. -- mvh Morten Brekkevold UNINETT ____________________________________________________________________________________ Be a better Globetrotter.

I get some errors from: Cron <navcron@nav> $BINDIR/getBoksMacs.sh $NUM_THREADS the body of the message is at the end of this msg, there's something i can do to fix it or the set of libs that comes with Centos5 is too much different to let NAV work as it is?

Given the OID compatibility report you sent, NAV should be able to detect the ports on this routing switch; the ports are detected using standard mibs. Yet you say that _no_ ports are detected? If that is so, I would like to see what getDeviceData.log says when it collects from this device. When it comes to modules, I must admit that NAV's support for HP equipment is lacking in several respects. The HP support was written and tested using the equipment that was available at the Norwegian University of Science and Technology at the time, and these were all HP SwitchStacks. Consequently, NAV only recognizes virtual stacking in HP equipment, and cannot at all recognize modules in your HP chassis. It is in our plans to implement more generic module support through interpreting the ENTITY-MIB. I'm guessing your HP9304M presents a fairly correct view of its physical contents through its entPhysicalTable? Since I have no access to a 9304M myself, but am planning to code the ENTITY-MIB support, I would greatly appreciate it if you could provide me with the output of this table from your device; running this command on your NAV server should do it: snmptable -Ci -Cb -v2c -c <community> <ip> entPhysicalTable -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Sep 6 12:12:49 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Sep 6 11:13:05 2007 Subject: [Nav-users] Centos 5 and NAV 3.2.2 In-Reply-To: <200709031022.52942.barbieri.marco(a)unimore.it> References: <200709031022.52942.barbieri.marco(a)unimore.it> Message-ID: <46DFC491.4070702(a)uninett.no> Marco Barbieri wrote, On 03-09-2007 10:22: > first of all i'm trying to run NAV 3.2.2 on a Centos 5 and i know it's not > supported, That depends on what you mean by "supported" :) We do not guaruantee support to anyone, but you should be able to have NAV up and run on any Linux distro.

Mailing list problems
by morten.brekkevold＠uninett.no 17 Jul '07

17 Jul '07

We still seem to be having problems with our mailing list setup. nav-commit and nav-dev are confirmed to be working fine, but nav-users apparently doesn't. Some subscribers seem to be getting the mails sent to nav-dev(a)itea.ntnu.no, while others are not (myself included). However, none of these mails are stored in the mailing list archives. I've asked the guys at itea.ntnu.no to take a look at this problem, but apparently all their postmasters have taken their summer vacations simultaineously (!), so I cannot really say when this problem will be fixed. I would have moved the mailing lists to a different server to ensure continued service, were it not for the fact that I'll be taking 4 weeks of vacation starting today. Therefore I've asked John-Magne, the second list administrator, to try to influence things at itea.ntnu.no while I'm gone. Some of you might get this e-mail, and some of you might not, I don't know. If some of you who receive this e-mail can respond to it, maybe we can gather enough clues as to what is wrong that the postmasters (or acting postmasters or whatever) at itea.ntnu.no can fix the problem. If not, the list may be defunct for the next 4 weeks :-( -- mvh Morten Brekkevold UNINETT

How to add Cisco 6506 in MetaNAV

I just installed MetaNAV. I succesfully added catalyst 3550 device (after adding the proper OID in the type table). I cannot add a Cisco catalyst 6506: I added the type (1.3.6.1.4.1.9.5.45 ) but no modules are discovered from the device. # snmpwalk -v 1 -c public 192.168.10.101 .1.3.6.1.4.1.9.5.1.3.1.1.17 SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.1 = STRING: "WS-X6K-SUP2-2GE" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.2 = STRING: "WS-X6K-SUP2-2GE" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.3 = STRING: "WS-X6416-GBIC" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.4 = STRING: "WS-X6416-GBIC" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.5 = STRING: "WS-X6348-RJ-45" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.15 = STRING: "WS-F6K-MSFC2" SNMPv2-SMI::enterprises.9.5.1.3.1.1.17.16 = STRING: "WS-F6K-MSFC2" How can I add the above modules? Thanks in advance to anyone that can explain me how to add modules. Davide.

The reason for this is that it is quite impossible to create good generic config for servers in Cricket, and that the attempt NAV does spur a lot of errors . I strongly suggest that you make your own cricket-config for server statistics and remove the one present. To remove the existing config, delete the server-directory from $cricket/cricket-config, and edit the cricket-config/.nav-file (mind the dot) and remove servers from the dirs-variable. This will make sure the config will not be recreated. Then run compile from $cricket/cricket as navcron (sudo navcron ./compile). However, we are working on a new version of the script that makes cricket-config. This version will combine the advantages of the NAV-database and user-customization in a much better way than today. Both we and, I hope, our users look forward to this. :) Yours, -- John-Magne Bredal NTNU

I am getting these errors in my collector logs. Cricket isn't collecting from some router due to an snmp.pm error.

The first happens as getDeviceData tries to update the database to register that a box supports a given SNMP OID. The second happens as NAV tries to update an entry in the swport table. You'd have to look at the code of the JDBC driver to be able to see what could cause NullPointerExceptions at those particular lines (AbstractJdbc2Statement.java:53 and AbstractJdbc1Statement.java:274), but I don't even know which version of the driver you are using. -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 12:40:27 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 12:40:30 2007 Subject: [Nav-users] NAV 3.2.1 from snapshot on ubuntu server problem In-Reply-To: <45F511D2.7080401(a)carnet.hr> References: <45F511D2.7080401(a)carnet.hr> Message-ID: <45F930AB.7010902(a)uninett.no> Silvije wrote, On 12-03-2007 09:39: > File "/usr/lib/python2.4/site-packages/mod_python/apache.py", line > 461, in import_module > f, p, d = imp.find_module(parts[i], path) > > ImportError: No module named nav > > > I am using apache2 and configured nav web as virtualhost on port 8888 > > Is this ok to do or not? > > I think I got all dependencies right.

I'm not sure that Apache/mod_python would pick up on the PYTHONPATH environment variable, you might have to use some mod_python configuration parameters in your Apache config to specify the python path. A better approach for an installation from source on Ubuntu would be to add a file in /etc/python called 'sitecustomize.py', and add something like this to it: import sys sys.path.append('/usr/local/nav/lib/python') This module will be loaded by all Python programs that are run on your Ubuntu system. On another note, you should try the Debian package of NAV on Ubuntu. I think Ubuntu is similar enough to Debian for it to work, and it would make life a lot easier for you (dependency-wise, anyway). -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Mar 15 12:48:56 2007 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Mar 15 12:49:02 2007 Subject: [Nav-users] LDAP Authentication In-Reply-To: <4ddd24660703120903gc499f13gfacb5ffaf19eba9c(a)mail.gmail.com> References: <4ddd24660703120903gc499f13gfacb5ffaf19eba9c(a)mail.gmail.com> Message-ID: <45F932A8.5080702(a)uninett.no> Greg Cooper wrote, On 12-03-2007 17:03: > Is anyone using LDAP to authenticate users on the web interface? > > if so, how did you go about doing it? First of all, take a look at this URL: http://metanav.ntnu.no/moin.cgi/LdapAuthentication Second of all, NAVs LDAP authentication ability is somewhat limited yet. It was modeled after the LDAP schema used at NTNU, and isn't quite configurable enough to suit any kind of LDAP schema people might care to implement. Specifically, NAV will grant access to all users in the configured subtree, which is not always desirable. At NTNU there were separate subtrees of user accounts for different systems; there was also a subtree of NAV accounts which contained only a fraction of the total amount of users. It also makes assumptions about which attributes are used to store account names and user names, etc. Fixing this isn't a very high priority at the moment, but if anybody cares to do something about it, the code is located in subsystem/webFront/lib/nav/web/ldapAuth.py .

When I go through > Cricket and browse to that box, I see the stats and it works fine. > Is there something I can do to fix this? I have a theory about what's going on. If you add an IP Device to NAV, and NAV is unable to do a reverse lookup of its IP address, it will use the device's IP address as its sysname (NAV always uses DNS names in the sysname column, for some old, obscure reason). So when makecricketconfig.pl generates cricket configuration, it sees that the name of the box is 10.8.250.3, and creates config based on that. It also registers in the rrd_file table that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd belongs to this box. Then, later, NAV is able to perform a reverse lookup on 10.8.250.3 and sets the sysname of the box to DNS_NAME. Next time makecricketconfig.pl runs, it creates a cricket config entry for DNS_NAME, and ignores/discards the old 10.8.250.3 config. It also registers that /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/DNS_NAME/9_16.rrd belongs to this box. So now, the rrd_file table says that there are two RRD files for the 9_16 interface of DNS_NAME. One of them might no longer exist, but it might sort first in the table, making the IP device browser attempt to use this file instead of the real one. I think you can fix it by running "cleanrrds.pl -r", which removes any entry from rrd_file that doesn't correspond to an existing file in the file system. This is just my best guess, though. I don't know why /usr/local/nav/cricket/cricket-config/../cricket-data/switch-ports/10.8.250.3/9_16.rrd disappears, though, as nothing in NAV deletes that. It might never have been created (e.g. makecricketconfig was run, but Cricket was never run until the DNS name had been resolved and makecricketconfig ran again). -- mvh Morten Brekkevold UNINETT >From annaliu at us.ibm.com Sat Mar 24 10:42:11 2007 From: annaliu at us.ibm.com (Anna Liu) Date: Sat Mar 24 18:42:24 2007 Subject: [Nav-users] Question in Configuring NAS Message-ID: <OFA51A9242.C09767EA-ON882572A6.006D229B-882572A8.00613DBD(a)us.ibm.com> I'm new in NAV.

Then the cron jobs will have the updated info to collect on. Regards, Greg On 3/24/07, Anna Liu <annaliu(a)us.ibm.com> wrote: I'm new in NAV. Just recently got it installed on RHEL 4.0.

Yes, we (UiO) uses LDAP for authentication. In /usr/local/nav/etc/webfront/webfront.conf : [ldap] enabled = yes server = ldaps://xxx.uio.no binddn= cn=yyy,cn=zzz,dc=uio,dc=no And if your ldap requires it (ours do), you allso need correct settings in /etc/openldap/ldap.conf.

You have probably not disabled SELinux like it says in the installation manual. Run this command as root to check: [root@nav3 ~]# sestatus SELinux status: disabled If you get something other than "disabled" you will either have to configure SELinux to work with NAV or disable SELinux. If you want to disable SELinux do this: To just test if this is the problem run this command: [root@nav3 ~]# setenforce 0 and try to reload the webpage. To disable it permanently edit this file: /etc/sysconfig/selinux to say: SELINUX=disabled and reboot the server. - Roger

Memory leaks in getDeviceData
by morten.brekkevold＠uninett.no 09 Mar '07

09 Mar '07

Some of you have noticed problems with getDeviceData running out of Java heap memory, and then getting out of sync with the PostgreSQL database driver - it ends up doing strange updates to the database. The issue is described in this bug report: http://sourceforge.net/tracker/index.php?func=detail&aid=1675508&group_id=1… For the technically inclined, here's a complete summary: I've traced the problem back to the Java SNMP package provided by drexel.edu. This package is used by the getDeviceData and getBoksMacs NAV processes to perform SNMP queries. The problem is an infinite loop, in which the library sends the same GETNEXT request over and over, and growing a list of SNMP responses until the heap is full. In a getDeviceData context, this problem can occur during OID testing of a device (This is when gDD attempts to figure which SNMP OIDs a new device supports). When the OID tester attempts to query an OID using GETNEXT requests, it uses the Java SNMP package's method for snmpwalking a MIB tree (retrieveMIBTable). If the OID is outside the MIB view of an SNMPv2c device, the device will respond with an SNMPv2 endOfMibView exception. Ufortunately, the retrieveMIBTable method of drexel's Java SNMP package treats this exception as just another value and adds it to the list of responses. Since the exception's object identifier is the same as the one used in the GETNEXT request, the method will continue to issue GETNEXT requests for the same OID until it no longer receives any response, or until it runs out of memory, whichever comes first. I've written two different patches to fix the problem in the Java SNMP Package, and I have submitted these patches to the upstream authors. The simplest patch is available at the aforementioned bug report page, for those who want to apply it themselves. I'm also planning to write a workaround for NAV. It is quite unnecessary for the NAV OID tester to walk entire SNMP tables just to test OID compatibility. Issuing a single GETNEXT request should be enough to determine whether the OID is supported or not. By doing this, the OID tester can avoid using the retrieveMIBTable method of the drexel library entirely. -- mvh Morten Brekkevold UNINETT >From gwc2004 at gmail.com Sat Mar 10 07:49:28 2007 From: gwc2004 at gmail.com (Greg Cooper) Date: Sat Mar 10 14:49:35 2007 Subject: [Nav-users] getDeviceData Java errors Message-ID: <4ddd24660703100549m38e8bf53l858b508ce07b4069(a)mail.gmail.com> Hi all.

Is there anything I should do after > following the RHEL/CentOS installation guide to configure cricket to handle > that many ports? 9700 ports are a considerable amount. Cricket is rather CPU and I/O demanding, so it depends a bit on your hardware. If you have dual CPU's you may get an increase in performance by configuring Cricket to use several processes. This is done by editing the subtree-sets file (located in the cricket-directory). This file defines the "sets" of directories you collect from. One set equals one process. Try to add one (or more) sets, preferably so that the number of ports in each set is about the same. Also remember to update the $NAVinstall/etc/cron.d/cricket file and add a cron-job for the new sets (the collect-subtrees job), and restart cricket with "nav restart cricket". NB: This will increase the CPU and I/O load on your server considerably. Cricket is not the most efficient program, and for bigger installations it is common to use a dedicated server (or more) for Cricket. At NTNU we are going to test this as we are currently only gathering data from a small subset of our network because of the load on the server. There was a discussion on the cricket-users mailing list some months ago (first post from 21. nov.) regarding this issue. It had the title "Huge Cricket installations". It seems that the forum is down (http://sourceforge.net/mailarchive/forum.php?forum=cricket-users) but if it comes up you can read that thread for more thorough information. > I read that collect-subtrees can collect from devices in parallel.

Can you send us the list of OIDs NAV classifies the box to and we can take it from there. Typically the data from https://yournav/report/netboxsnmpoid?netboxid=id of your foundry (linked from the "All IP devices report, right column).

You probably mean bridge table, anyway, are you sure? For Cisco I've read that you can do this: "You can generate SNMP traps whenever a MAC address change occurs by enabling the set snmp trap enable macnotification command in conjunction with enabling the set cam notification and set cam notification historysize commands." I haven't tested it yet, maybe someone out there has? We have SNMP trap on TODO for NAV 3.3, we are thinking of an implementation that can trigger certain scripts on a given snmp trap oid. We see to very interesting use cases: * when linkdown/up trap is detected update the cooresponding link value in the swport/gwport database table. * when a new mac address is seen/gone trigger a script that opens/closes corresponding machine tracker records (cam table). This script could also post alarms regarding wanted mac addresses. - Vidar

Can this be done today? On a small scale such as having only 1 MAC address that you need to catch, you could configure your DHCP servers to assign this MAC a specific IP. With the suspect confined to a known set of IP addresses you could also setup a sniffer on the external routes to capture all traffic from those IPs to see for yourself if there is abuse.

Get error when adding IP device "Gw router - layer 3 device"

Some devices also return integer values for serial numbers instead of strings - attempting to encode an integer object as if it were a string will fail miserably, as in your case. I've just committed a fix for this to the repository (r3785). We're expecting to release NAV 3.2 within a few weeks, so I don't think you will see this in a bugfix release before that. Several others have reported this problem, and a workaround has been suggested: Use bulk import to insert the devices that cause this error - the serial numbers are not retrieved and checked in this manner during a bulk import. -- mvh Morten Brekkevold UNINETT >From barbieri.marco at unimore.it Mon Jan 8 12:06:48 2007 From: barbieri.marco at unimore.it (Marco Barbieri) Date: Mon Jan 8 12:07:05 2007 Subject: [Nav-users] Problem with HP 9304m & vlan Message-ID: <200701081206.48961.barbieri.marco(a)unimore.it> Hi all, i'm trying to use NAV 3.1.1 in my environment, my main problem seems to be that my network in mainly based on HP router/switches: 9304m (foundry/hp), procurve 5304, 5308, 2824 etc.. and a couple of cisco.

Hi, I have experience the same thing. I have notice something but not sure if this is the problem.

When I added the server navcron started a process called Java, and this process took more and more memory until the computer running nav crashed. I removed the ip device from the database but then cricked displayed this error at the bottom of the cricket webpage: Config tree needs to be recompiled: Referenced file /usr/local/nav/cricket/cricket-config/servers/"IPofServer"/"IPofServer" The two questions I got then is: what is that java prosess that started the trouble and how can I prevent it from happening the next time I added a server? How do I get that Cricket error fixed? I feel more comfortable in a windows enviroment but NAV offer some good functionality that I think could be useful in our network, so I would really like to get this working. ---- mvh Jan Egil ?rtun Sauda Kommune >From roger.aas at hsh.no Thu Nov 23 11:17:31 2006 From: roger.aas at hsh.no (Roger Aas) Date: Thu Nov 23 11:17:57 2006 Subject: [Nav-users] Updated InstallingOnRHEL4 to cover NAV 3.1.1 Message-ID: <4565753B.1080102(a)hsh.no> I have the last days done some much needed editing of my installation description of NAV on CentOS and RHEL.

Roger: Thanks for the gracious and quick response to my simple problem. I just could not see how the installation could proceed without being logged in as root and your response has provide both the rational for the local user creation, and a good approach to completing the install away from the server room. Thanks for the PuTTY link. To answer your last question.. I am using the "InstallingOnRHEL4 for v3.1" with the edits by Morten Brekkevold; ### 14.11.2006 by Morten Brekkevold: ### - Updated for NAV 3.1.1. ### - NOT TESTED Thanks again, the help was much appreciated.

Newbie Problem loading NAV on CentOS 4.4
by rkillick＠niagara.com 17 Nov '06

17 Nov '06

Hello: I am trying to load NAV 3.1.1 onto a basic CentOS4.4 installation. My problem is likely embarrassingly simple and concerns a point near the start of the "InstallingOnRHEL4" document for NAV3.1.1. .. at the section. ## ## Make a local user ## useradd -c "John Doe" nn passwd nn .. I create a simple user called "NAVNIA" as well as an appropriate password. Soon thereafter you are asked to reboot and log in as the new user. .. Logged in as NAVNIA, that user has no root privilege or access to root level commands that now have to be executed to complete the install. While I know it is best practice not to run as root, I just don't get what I need to do to have the new user (NAVNIA) complete the install. It doesn't seem right to simply su root every time you need that privilege. As I siad. a very basic question I'm sure, but my MS-Windows admin experience is simply no help here and my access to Linux help is simply zero. I am quite interested in getting NAV up and running as a means of show-casing the OpenSource possibilities as well as hhoping to see a viable alternative to our Pergrine PND NMS. Our network has about 1600 devices and NAV looks very inviting! Any insight would be appreciated. Bob Killick

You did not follow the database instructions properly. The table you just selected from is not supposed to be in the `manage` database, but rather in the `navprofiles` database.

Ah. I discovered that myself while creating the bug you just pointed out ;) I got tired of AlertEngine's incessant verbosity when start/stopping and querying for status, so I changed its init-script to use the shell-script based pid-file probing. The "garbage" is actually a unix timestamp, referring to when the alertEngine daemon was started. When querying the alertengine program directly (as in pre-3.1.1), it would use this to tell you how long it had been running. Why on earth the author put it in the pid file, I don't know. I thought about removing the timestamp completely from the pid file as I changed the init script, as it bothered me somewhat - but in my Linux-centric world it worked fine without removing it. Looks like I'll have to reconsider... -- mvh Morten Brekkevold UNINETT >From morten.brekkevold at uninett.no Thu Nov 9 11:17:28 2006 From: morten.brekkevold at uninett.no (Morten Brekkevold) Date: Thu Nov 9 11:17:46 2006 Subject: [Nav-users] Garbage in alertengine.pid In-Reply-To: <4552FA85.5080507(a)uninett.no> References: <200611090714.kA97ENQU070237(a)barnetv.cc.uit.no> <4552FA85.5080507(a)uninett.no> Message-ID: <45530038.7090207(a)uninett.no> Ingeborg Hellemo wrote, On 09-11-2006 08:14: >> /# cat /usr/local/nav/var/run/alertengine.pid >> 65218 1162996552 >> >> The first number in the pid-file is indeed the pid, but why the garbage at the >> end?
