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.

Weird Report behaviour in Internet Explorer

Problem sending SMS alerts
by Sjøholt Steinar Otto 26 Mar '09

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"...

There is a known problem with the Netmap on Windows. We thought we fixed this bug in NAV 3.5.1, but it appears to still be present for Windows users (oddly enough).

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

Hi all, i did a fresh debian install and then a fresh nav install, configured everything like suggested in /usr/share/doc/nav/README.Debian everything was smooth but the installation of the java-jdk that i had to add by hand. Then i added 5 or 6 HP Procurve machines to nav via Edit database and started to see this in: /var/log/nav/getDeviceDatagetDeviceData-stderr.log : ----- java.lang.NoClassDefFoundError:

Instance is now set to nothing?

Hello, I don’t know the root of this problem, but I seem to have a module that has either been switched or replaced that is generating a load of error messages in /var/log/nav/cricket/normal.log. The error messages look like this, but I see no information about which device is generating these errors while being polled: [12-Feb-2009 14:58:39*] Failed to map instance for 4_47. Instance is now set to nothing. Use of uninitialized value in join or string at /usr/share/cricket/lib/snmp.pm line 92.

Hi! I'm the one that try to install NAV in Debian. But I stucked at "aptitude install nav" command as Terminal told me "the following packages have unmet dependencies: nav :Depends: java5-runtume which is a virtual package. or sun-java5-jre which is a virtual package. Resolving dependencies"" the following action will resolve these dependencies: Keep the following packages at their currect version: nav [Not installed] python-pysnmp-common[Not installed] python-pysnmp2 [Not installed] python-pysnmp4 [Not installed] python-pysnmp4-mibs [Not installed] Score is -9965 Accept this solution? [Y/n/q/?]" What should i do next? Any help will be grateful My country is hard to find some experts to fix this problem T_T
