Twisted SNMP Patch Question
by Greg Cooper 15 Nov '11

15 Nov '11

Hello, I have a question about this from the NOTES: The latest TwistedSNMP version (0.3.13) contains a bug that manifests in table retrieval operations. Timeouts and retries aren't handled properly, and this may cause slow or otherwise busy devices to be bombarded with requests from NAV. The `contrib/patches` directory contains a patch for TwistedSNMP that solves this problem. The patch has been submitted upstream, but not yet accepted into a new release. Alternatively, you can install `pynetsnmp` for improved performance. I think I am running into the Twisted SNMP timeout issues talked about here. So my question is this: When it says, "Alternatively, you can install pynetsnmp for improved performance" does that mean that instead of patching TwistedSNMP, i can just do an apt-get install pynetsnmp and then I don't have to worry about the Twisted SNMP library's problems? If so, do I have to uninstall twisted SNMP? If I still have to patch Twisted, then what is the best way for me to go from using the standard debian packaged TwistedSNMP to using the patched one I build from scratch? I don't want to be stuck where I have both installed, but it is still using the old version. Thanks in advance, Greg

Cricket-config and GW which does not support ifName
by Ingeborg Hellemo 14 Nov '11

14 Nov '11

The old (3.5) NAV's makecricketconfig.py used interface-indexes directly when collecting router-interface data. The new (3.8) NAV's mcc.py uses a map based on ifName: map interface-name base-oid = ifName match = %ifname% We have a couple of GWs (firewall nodes running some variation of Linux) which does not support ifName. This breaks the collection of router-interface. I know what is needed of a work-around (use ifDescr instead), but wonder if we are the only ones who have this kind of (old) equipment? Will anyone be interested in patching mcc.py or shall I just implement a local hack? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

ipdevpoll daemon 3.9.1
by izar＠condornet.sk 14 Nov '11

14 Nov '11

Hi all, I'm sorry for spam, but i would like to make sure that it's a real bug not just my mistake/misunderstanding before filling in the bug into lauchpad. I upgraded NAV to 3.9.1 this monday (deb 5.0) from rep. and I noticed that ipdevpoll job is not running as it supposed to. If I understand it right, then ipdevpolld should be daemon process running all the time, however in 3.9.1 it's not: ./ipdevpoll status ipdevpolld does not seem to be running... If I restart NAV ,then ipdevpoll runs just once .... Thanks, milo

ipdevpoll does not set sysname unless snmp is enabled
by Ingeborg Hellemo 14 Nov '11

14 Nov '11

During migration from old NAV (3.5.6) to new NAV (3.9.1) I "Bulk import"-ed all our hosts. I notice that ipdevpoll does not set correct sysname on hosts that does not run a configured snmpd. nav=> select * from netbox where ip='129.242.5.142'; netboxid | ip | roomid | typeid | deviceid | sysname | catid ----------+---------------+--------+--------+----------+---------------+------- 1100 | 129.242.5.142 | ma | | 87934 | 129.242.5.142 | SRV This means I now have several hundred boxes (mostly windows servers, virtual IPs and misc "stuff") lacking a proper sysname, even though they are registered i DNS. ipdevpoll.log: 2011-08-31 10:07:02,584 [WARNING plugins.dnsname.dnsname] [inventory 129.242.5.142] Box dnsname has changed from u'129.242.5.142' to 'radius1.uit.no' 2011-08-31 10:07:36,612 [ERROR jobs.jobhandler] [inventory 129.242.5.142] Job 'inventory' for 129.242.5.142 aborted: SNMP request timed out If I edit the host via the Seed DB web interface the correct sysname is saved: nav=> select * from netbox where ip='129.242.5.142'; netboxid | ip | roomid | typeid | deviceid | sysname | catid ----------+---------------+--------+--------+----------+----------------+------ - 1100 | 129.242.5.142 | ma | | 87934 | radius1.uit.no | SRV I presume this is a bug. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

network time is incorrect on cricket
by Ryan Lin 14 Nov '11

14 Nov '11

hi all, we have installed nav on one of our servers. everything is functioning properly except the time on the cricket. the time on the cricket is showing the UTC time. i would like to change it to the PDT time, but don't know how as there is no documentation available on how to change the time in nav. the server that's hosting the nav is synchronized to a public NTP server, so there is no issue with that. does anyone know how to correct the time in cricket on nav? thanks.

by Duarte Franco 12 Aug '11

Hi I am trying to get the switch information of an IBM Bladecenter. The switch modules are Nortel Networks Layer 2-3 GBE Switch Module(Copper). OID is 1.3.6.1.4.1.1872.1.18.1 Is there any way to make the data acquisition of this type of switch? In the "IP Device Info" i saw 0 ports an the cricket have no data. There is some workaround for this type of switch? Best Regards

IPv6 Address
by Shinn, Mark 04 Jul '11

04 Jul '11

I'm running the NAV 3.8.6 and I get inconsistent reporting of IPv6 hosts. Some show up, others do not, even though they appear in the Cisco show ipv6 neighbor results. I don't see this problem with IPv4. Is this a known issue? Workarounds?

Bulk updates of database
by Sigurd Mytting 15 Jun '11

15 Jun '11

Hi! Due to organizational changes I need to update names of about 250 locations and change organization on about 800 devices, is there any way to do this without removing/adding them all? My first thought is SQL, is that the way to go? If so, there is 375 tables in the database, hints on what to update would be appreciated! Cheers, -Sigurd
