NAV snmptrapd handler help!
by Zhi-Wei Lu 14 Des '17

14 Des '17

Hi NAV gurus, I am in the process of learning how to use the snmptrapd handler for NAV. I hit a few road blocks along the way. I first test a simple home-made snmptrap (V1), what is the procedure to incorporate it into NAV snmptrapd. Where do I put the text mib files? /usr/share/snmp/mibs? Do I need to convert the text mib file into *.py in the directory (using smidump ?) /usr/share/pyshared/nav/smidumps ? I need to modify /etc/nav/snmptrapd.conf to add our own handler and put it in /usr/share/pyshared/nav/snmptrapd/handlers/ In my trap handler, I need to tell it process the trap with trap.genericType match what we define it. But I still could not get it to work properly. I would appreciate if someone can point me to the right direction, as I still miss a few pieces here and there. Thank you.

nav log time stamp issues: local time and UTC on different log files
by Zhi-Wei Lu 11 Des '17

11 Des '17

Hi NAV gurus, I noticed that some of the NAV log files use "local time" (here in California), 2017-12-07 15:56:13,973 [INFO] [nav.statemon.db] Returned 0 checkers while the other use UTC+1 in time stamp: 2017-12-08 00:50:14,898 [INFO] [nav.snmptrapd] Snmptrapd started, listening on 0.0.0.0:162, [::]:162 What do I need to make all log files using the local time stamp? Thank you. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155

Netmap showing connections that do not exist anymore
by Oscar Patricio 08 Des '17

08 Des '17

Hi, I have been using NAV for quite some time and I am really satisfied with the tool. So much so, that I implemented it at my new job. That being said :) I have a question: the Netmap application is showing me connections that do not exist anymore. This means, they were once established, but have been disabled (I am talking about connections between two network switches, between which the cables have been removed and the interfaces have been shutdown) a couple of months ago. Because the network I am managing is not very big, this is not a big problem because I know those connections in the Netmap are "fake". This is, however, a bit annoying, and I would like the map to reflect the actual topology of the network. So my question is: is there any way that I can force a redrawing of the map? Or a way to force nav to delete that connection from its database? Thanks in advance!

New to NAV, supported devices
by Vinsonnaud Ludovic 07 Des '17

07 Des '17

Hello, Sorry about my english, I'm french so everything may not be understood :-) I'm new to NAV and this software seems very interesting for my needs. I'm managing the network in an Engineer School (IOGS) and CNRS Labs (LCF and LP2N) based in 2 sites (near Paris and near Bordeaux). I've got an heterogeneous group of switches because we begin to change our 100Mb switches by 1Gb and 10Gb ones. For the moment we own : - Dell S4048-ON (force10) used for routing - Dell N2048 - Dell N4064 - Cisco 2960s - Cisco 3750 My switches are recognized pretty well after some tweaking. For Cisco 2960, everything works. Sometimes I've got timeout and "failed" changes so I need to wait before trying again (especialy vlan change). For Cisco 3750, it's the same For Dell N2048, I'm a bit confused because if I have this command "switchport access vlan 524" already set in the switch and I ask to change the vlan from 524 to 525 with NAV, it adds this command "switchport general pvid 525" but doesn't delete the old one. So why change a "switchport access" by a "switchport general" ? Is it better to have a "switchport mode general" in default config ? Switchport mode access is the default mode, the 2 combined commands will not work as intended I think ? I've not yet tested S4048 and N4064. -- Regards, IOGS Logo <https://www.institutoptique.fr> *Ludovic Vinsonnaud * - Ingénieur Réseau basé à Bordeaux, bureau F108 (IOA, Rue François Mitterrand, 33400 Talence) *Institut Optique Graduate School* 2 Avenue Augustin Fresnel - 91127 PALAISEAU Cedex Tel. +33 5 57 01 71 52 - Mob. +33 6 08 08 41 05

Changing Link Capacities Netmap
by William Daly - Network Specialist, VUSD Technology 08 Nov '17

08 Nov '17

Hello, I have sort of a different question. Here a bit of context: We currently have 17 sites throughout our school district. All of these have a 1Gbps uplink to our main district office. However, most of these sites are throttled at 100 Mbps. Of course NAV sees these links at 1 Gbps. The issue that I have is when viewing our network topology through Netmap it shows bandwidth usage based on 1 Gbps. However, the sites run at 1/10 the actual link capacity. Is there a way to 'change' Netmap to show bandwidth usage based on a different threshold? Thank you William Daly

Multicore support IPdevpool and Django Errors
by William Daly - Network Specialist, VUSD Technology 16 Okt '17

16 Okt '17

Hello, I am currently experiencing an issue with multicore with IPdevpool being enabled and encountering many errors. Essentially when I enable multi core support, the web gui stops rendering graphs at a high frequency and things do not load. In the logs it appears it shows errors with django. As soon as multi core support is turned off everything returns to normal, however my graphs become very spotty. Thanks, Will

Prefix and VLAN problems
by William Daly - Network Specialist, VUSD Technology 13 Okt '17

13 Okt '17

Hello, I am also having issues with prefixes and the corresponding VLAN tab. Initially, I went through and entered in all of my prefixes, with corresponding VLAN's, net identifications and usage type. However, after I populated the data base with nodes, the prefixes disappear and now when I go to the VLAN tab, all that shows is the net type and VLAN. I cannot edit net identifications. When I go to edit and change the organization and description, none of the changes hold. Any ideas? Thank you William Daly

Webfront authentication with encrypted LDAP to Windows Server fails
by Roger Aas 28 Sep '17

28 Sep '17

Hi, I have the NAV webfront LDAP authentication working with a Windows AD server, but only with unencrypted traffic on port 389. In the file /etc/nav/webfront/webfront.conf port = 389 encryption = none It works well with search for user in the AD tree and group requirement. But if I change encryption to tls, or port to 636 and encryption to ssl then it fails. Anyone have this working? If yes, what did you have to do to get it to work? I can not use it as it is as both the user account used for binding to the server and the user trying to authenticate have their passwords in cleartext in the packets. Best regards, Roger

Hello, I was curious as to the disk space usage that NAV will potentially use? How far back will it keep data for? I got ours up and running last week. We have roughly 550 nodes. Thanks, Will

ServiceState alert showing in UTC timezone
by Bruce Zhang 14 Sep '17

14 Sep '17

Hi there, Sorry to bother you all again. It's really wired. I have changed time_zone in nav.conf and all time is correct on the front page. But only the Service state alert's start time and end time is showing in UTC timezone. I went through database and confirmed those time was recorded by UTC timezone, as below: SQL: select * from manage.alerthist As you can see, the other’s alert in thresholdState is correct. I also looked into python code, In python/nav/models/event.py class AlertQueue(models.Model, EventMixIn): time = models.DateTimeField() class AlertHistory(models.Model, EventMixIn): start_time = models.DateTimeField() I changed those code to models.DateTimeField(default=dt.datetime.now), but still got same issue. I was just wondering has anyone run into the same problem? Cheers. Bruce
