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

07 Dec '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

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

Hi, Everything is working like a charm now, except GEOmaqp. Still no links between locations? Whatever setting I try, nothing shows up…… Only the dots on the locations change from grey to green when playing with the settings….. Anyone a clue/hint?

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

Could we updated NAV port metrics every 1 min?
by Bruce Zhang 11 Sep '17

11 Sep '17

Hi all, I am a network administrator and new to NAV. I really like NAV and am going to use it. But I found the Port Metrics Traffic graphs is updating every 5 mins.(I knew it's default intervals for NAV) I want to get more accurate Port traffic graphs, so could we change it from 300s to 60s? I did research and changed storage-schemas.conf(added 60s:1d) and used whisper-info to ensure those ports traffic wsp files have been changed to 60s. But I still can't get correct data via rickshaw JS and NAV still collected data in every 300s. So is that possible to change it? Or someone can point me to the right direction? Thanks. Bruce

Delayed alerts
by Roger Aas 04 Sep '17

04 Sep '17

Is it possible to configure alerts for a boxdown alert to be sent after a specified amount of downtime, f.ex. 4 days? I have a customer with some Cisco IR809 industrial routers installed on LNG trailer trucks that go active when the trailer is started and goes down when the trailer is parked. This means the router goes down and comes up all the time, we do not want alerts for that. But if the router does not become active after f.ex. 4 days the customer would like to get a message about that, maybe it means there is some other problem with the connection that they need to check. Is this possible with NAV? I only find "weekly at predefined time", but if I set the "Weekly dispatch time" to "08:00" and "Weekly dispatch day" to "monday", and the truck is parked Sunday evening, I will get a message Monday morning that it is down, even if it has been down for just some hours. I basically want a to be able to set a delay for alerts that counts down a specified amount of minutes/hours/days before sending a boxdown alert. Best regards, Roger
