Announcement: NAV 3.13.0b1 released
by Morten Brekkevold 14 Des '12

14 Des '12

A beta version of the next NAV feature release, version 3.13.0b1, is now available for download at Launchpad: https://launchpad.net/nav/3.13/3.13.0b1 The 3.13.0b1 release adds the following user-visible features and improvements: * The eventEngine has been rewritten to Python. This was the last remaining Java component of NAV, meaning Java is no longer needed for installing and running NAV. * VLANs are now searchable from the Navbar. * IPv4, IPv6 and MAC host counts for each VLAN is now graphed over time. * NAV is now able to detect and graph data from sensors on Cisco Nexus devices. * Maintenance tasks can now be configured to end automatically when all components involved in the task are up. * IP Devices that are down can be placed on immediate maintenance until up again directly from the status page. * Subscriptions to MAC address prefixes are now possible in Macwatch. Use with caution! And contains fixes for these reported issues: * LP#305435 (Sort by "Start time" or "End time" in machinetracker) * LP#305441 (Button for "Put on maintenance immediately") * LP#317800 (Color gradient to express utilization of IPv6 subnets) * LP#341703 (Manual detention does not pursue client) * LP#361530 (Arnold: Predefined detention does not exponentially increase detentions) * LP#744932 (Arnold should give warning if snmp write is not configured) * LP#833959 (make install overwrites nav.conf and db.conf) * LP#922793 (Possibility to set end time = "until device is up again " in maintenance) * LP#961097 (Don't list cancelled maintenance tasks in active list) * LP#961100 (Show component details in maintenance task list when there is only a single component) * LP#1057509 (Mouseovers with number of active IPv6 addresses in Subnet Matrix) * LP#1057511 (Get sensor information from CISCO-ENTITY-SENSOR-MIB) * LP#1062130 (NAV should graph IP address usage per prefix) * LP#1069773 (macwatch should be able to look for MAC address prefixes too) Remember, this is still beta status, and should not necessarily be considered production ready. 3.13 features two major rewrites, one for the eventengine one for the port blocker, Arnold. If you want to help us test the beta version, you are most welcome. Don't forget to check out the release notes, and please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible.

No, recent versions of NAV will only check the specific VLANs reported by the device itself through the queries I sent you examples of.

That's weird; the code involved here doesn't distinguish between device categories, it just checks what VLANs the device reports, if any. Could you share with us the actual responses given to the snmp queries you performed (censoring any secrets from the community outputs)? > So, can this be related to Cisco model 28xx or is this related to > configuration on the device when it comes to VLAN/VTP?

Cisco Routers SNMP Trap issue
by Mattias Torsfred 07 Des '12

07 Des '12

Hi, I have setup a NAV 3.12.2 and started to add Cisco L2 and L3 equipment into the seed database. I use an other software to monitor the devices as well. When it comes to Cisco routers (not Cisco L3 switches) I get many SNMP Traps "Too many SNMP authentication failures . Check for hacking attempt on x.x.x.x" and "SNMP incorrect community name...". I am aware of the issue/design of NAV when it comes to VLAN browsing and that this might be the case. Is there any configuration I can set on Cisco routers or in NAV to prevent this kind of behavior? I need to have the traps in case there actual is an SNMP brute force attempt. Kind Regards Mattias Torsfred Systemconsultant Funn IT

overdue jobs
by Matej Gregr 23 Nov '12

23 Nov '12

Hello, I have noticed, that NAV is reporting jobs as overdue, even though a job end with success. I believe the problem is caused by trigger trim_old_ipdevpoll_job_log_entries, which should delete the old jobs from the ipdevpoll_job_log table. DELETE FROM ipdevpoll_job_log WHERE id IN (SELECT id FROM ipdevpoll_job_log WHERE job_name=NEW.job_name AND netboxid=NEW.netboxid ORDER BY end_time ASC OFFSET 100); When there are 100 log entries for a job in the nav database the trigger will delete the newest logged job instead of oldest one. I believe, that the ORDER BY clause should be DESC not ASC. Regards, M.
