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

I'm now trying to install NAV on a server running Ubuntu 6.06.2 (2.6.15-54-amd64-server), following the procedure found here: http://metanav.uninett.no/installing_from_source_on_debian When running the 'make' command I get the following result: Cheetah.Parser.ParseError: Expected assignment operator at line 99, column 22 in file AcctChartsTemplate.tmpl Line|Line contents ----|------------------------------------------------------------- 96 | #if type($column) == type('') 97 | <th>$column</th> 98 | #else 99 | #set $title, $key = $column ^ 100 | #if $key == $sort 101 | <th><a href="?sort=-$key">$title</a></th> 102 | #else make[2]: *** [AcctChartsTemplate.py] Error 1 make[2]: Leaving directory `/home/janegils/nav-3.5.2/subsystem/radius/src' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/janegils/nav-3.5.2/subsystem/radius' make: *** [all] Error 1 Any idea what the problem is?

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
by Stokkenes Vidar 31 Mar '09

31 Mar '09

Hello all, This is most likely the weirdest error I've seen in NAV so far, and I can't really seem to trace where the "hidden" value is hiding. When I go to Reports, All IP Devices -> Advanced Search and put "Breivika" in the Location field and click search, I get the following SQL error: Configuration error! The report generator is not able to do such things. ERROR: column "r4g3n53nd" does not exist SELECT locationid,roomid,sysname,ip,catid,sub,typeid,typename,orgid,netbox.up,modules,swport,gwport,prefixcount,CASE WHEN Mem THEN 'Mem' ELSE NULL END AS Mem,snmp,sw_ver AS Software,serial,val AS Function,netbox.netboxid,prefixid FROM type RIGHT OUTER JOIN netbox USING (typeid) LEFT JOIN room USING (roomid) LEFT JOIN (SELECT netboxid,count(netboxid) AS gwport FROM gwport JOIN module USING (moduleid) GROUP BY netboxid) tempaggr1 USING (netboxid) LEFT JOIN (SELECT netboxid,count(netboxid) AS swport FROM swport JOIN module USING (moduleid) GROUP BY netboxid) tempaggr2 USING (netboxid) LEFT JOIN (SELECT netboxid,count(netboxid) AS modules FROM module GROUP BY netboxid) tempaggr3 USING (netboxid) LEFT JOIN (SELECT netboxid,count(netboxid) AS sub FROM netboxcategory GROUP BY netboxid) tempaggr4 USING (netboxid) LEFT JOIN (SELECT netboxid,count(netboxid) AS snmp FROM netboxsnmpoid GROUP BY netboxid) tempaggr5 USING (netboxid) LEFT JOIN (SELECT netboxid, count(netboxid) > 0 AS Mem FROM mem GROUP by netboxid) tempaggr6 USING (netboxid) LEFT JOIN (SELECT netboxid, count(gwportid) AS prefixcount FROM gwportprefix JOIN gwport USING (gwportid) JOIN module USING (moduleid) GROUP BY netboxid) tempaggr7 USING (netboxid) LEFT JOIN device ON (netbox.deviceid=device.deviceid) LEFT JOIN netboxinfo ON (netbox.netboxid=netboxinfo.netboxid AND var='function') WHERE r4g3n53nd = 'Search' AND locationid = 'Breivika' ORDER BY locationid,roomed I have no idea whatsoever where it is getting "r4g3n53nd". It looks like a password of some kind, but I can't find it in report.conf or front.html. Does anyone have a clue why I get this error? I am not able to reproduce the same error while using Mozilla Firefox. Any help appreciated :-) ------------------------------------------------------ Vidar Stokkenes Networking Consulant Networking and telecom Department HN IKT - Tromsø Tlf: 76 16 61 87 / 77 66 99 55 Cell: 95 87 99 42 e-mail: vidar.stokkenes(a)hn-ikt.no  Before printing, think about the environment

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

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"...
