Announcement: NAV 4.9.3 released
by Morten Brekkevold 28 Feb '19

28 Feb '19

The third maintenance release of the 4.9 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 8/9 (Jessie/Stretch) are available in our APT repository [2] as usual. The Debian packages for NAV 4.9 have been rebuilt using dh-virtualenv, which means that most of the Python dependencies are now embedded into the packages themselves. If you have previously added a priority apt pin for packages from apt.uninett.no, you may now remove it, as there are no longer any other packages needed from that repository to run NAV. Please also be extra aware of config file changes. Look out for `*.dpkg-dist` files in /etc/nav and make sure to update your running config. The virtual appliance currently being updated at the time of this writing, and will be uploaded soon. Changes ======= * #757 (devicehistory search by date ignores date) * #1792 (Precision of several Eaton/MGE UPS sensors are wrong) * #1812 (Malformed subid on (old) thresholdState events can cause status page and alert API endpoints to crash) * #1818 (Update ENTITY-MIB definition to RFC 6933) * #1855 (IPAM subnet suggest function is broken) * #1856 (Geomap doesn't work in NAV 4.9) * #1857 (E-mailing of business report subscriptions doesn't work) * #1862 (Please add case-insensitive matching on interface names in ipdevinfo queries for 'ifname') * #1865 (Servicemon resource leak causes all services to be reported as down) * #1871 (Alert detail headers are not present in e-mail notifications from AlertEngine) Please see the release notes [4] for more details. Happy NAVing everyone!

Fresh Install on Debian -> Graphite Unreachable
by Bothe, Mathias 20 Feb '19

20 Feb '19

Hello, i made a fresh nav installation on a fresh Debian 9 system. I installed the nav package by following the instructions here: https://nav.uninett.no/install-instructions/#debian After that I followed the instructions in /usr/share/doc/nav/README.Debian<https://raw.githubusercontent.com/Uninett/nav-debian/master/README.Debian> I skipped Part1, I did Part 2 to 6 as described. At point 4 Graphite, I followed https://nav.uninett.no/doc/latest/intro/install.html#integrating-graphite-w… I added the storage-*.conf files with symlink as described here: https://nav.uninett.no/doc/latest/howto/installing-graphite-on-debian.html Now I can Login into NAV, but Graphite is unreachable. So I have a few questions: Do i have to uncomment in file /etc/nav/graphite.conf? [carbon] # # NAV supports Carbon's UDP line receiver. Host and port information of # the backend can be configured in this section. # #host = 127.0.0.1 #port = 2003 [graphiteweb] # # Where is the Graphite web interface located. NAV needs this to get graphs # and data from Graphite. # #base=http://localhost:8000/ Do I have to create the graphite database and the apache webinterface by myself? As described here: https://nav.uninett.no/doc/latest/howto/installing-graphite-on-debian.html For me the installation instructions are not really clear and seem uncomplete. Can anyone help me? Cheers Mathias

Dell N2048P not saving
by Vinsonnaud Ludovic 07 Feb '19

07 Feb '19

Hello, When I use portadmin on a Dell N2048P, I change a port description for example and I clic on save. It say ok for change and ok for save very quickly. If I connect on the switch, the change is ok in the running-config, but when I check the startup-config, the change isn't done. I wait a few minutes and still no change. It is working well on Cisco 2960 and 3750 (despite sometimes it's slow if the stack is 8 switch) Can you help me find where is the problem ?
