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

Alert profiles

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

Cricket Tree needs to be recompiled
by Keith Latta 05 Nov '08

05 Nov '08

I keep getting "Cricket Tree needs to be recompiled" when I try and run statistics. I have tried running /usr/bin/cricket-compile. It always comes back with "Couldn't apply preserved file mode to /etc/nav/cricket-config/config.db.new". I am running this on NAV 3.4.4. Any Ideas?

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
