wsgi throwing errors when talking with ldap-server
by Ingeborg Hellemo 04 Nov '21

04 Nov '21

NAV 5.1.2 I had to upgrade the OS on my NAV-box, and hence all the software depending on libraries. After this I have wsgi throwing errors on me. Not all the time. Users local to NAV can log in just fine, but users who authenticate via ldap gets the error. I have tried to reinstall psycopg2. I have also switched from installing mod_wsgi from an OS-package to using pip Apache/2.4.51 (FreeBSD) OpenSSL/1.1.1l mod_wsgi/4.9.0 Python/3.7 The error is not connected to communication with the ldap-server (AD) Output with debug=true in webfront.conf ldap_create ldap_url_parse_ext(ldaps://XXXX.ad.uit.no:636) ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP XXXX.ad.uit.no:636 ldap_new_socket: 18 ldap_prepare_socket: 18 ldap_connect_to_host: Trying 129.242.xx.zzz:636 ldap_pvt_connect: fd: 18 tm: -1 async: 0 attempting to connect: connect success [Tue Nov 02 08:53:35.941429 2021] [wsgi:error] [pid 34769] [client 129.242.14.106:49209] Truncated or oversized response headers received from daemon process 'NAV': /usr/local/lib/python3.7/site-packages/nav/wsgi.py, referer: https://nav.uit.no/index/login/?origin=/&noaccess [Tue Nov 02 08:53:35.977367 2021] [core:notice] [pid 34758] AH00052: child pid 34760 exit signal Segmentation fault (11) Any ideas? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Announcement: NAV 5.2.1 released
by Morten Brekkevold 23 Sep '21

23 Sep '21

The first maintenance release of the 5.2 series of NAV is now out! This release fixes a particularly nasty regression bug in pping, which would prevent you from being alerted about boxDown events. If you are already running 5.2.0, we recommend that you upgrade as soon as possible. The source code is available for download at GitHub [1]. A new package for Debian 10 (Buster) is available in our APT repository [2] as usual. Packages for Debian 11 (Bullseye) have not been built yet. Please 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 has been updated. Changes ======= * #2304 (Display alert severity values in the event/alert details page) * #2306 ([BUG] pping is unable to report unreachable devices in NAV 5.2.0) * #2308 ([BUG] Alert Profile severity filters that ship with NAV are outdated) Please see the release notes [3] for more details. Happy NAVing everyone!

LDAP / ActiveDirectory issues
by Andrea Verni 02 Sep '21

02 Sep '21

Hi, I deployed NAV 5.14 on a debian 10 VM and configured LDAP authentication as from https://nav.readthedocs.io/en/latest/reference/ldap.html?highlight=ldap - however if using LDAP the login works randomly (need to try 2 to 5/6 time to login) while LDAPS never works. I did a test with ldapsearch on the same VM using both LDAP and LDAPS and both works so no issues with basedn or manager credentials nor with certificates. Is anyone else experiencing the same issue ? Other LDAPS based applications we use internally sucessfully connect to same AD servers. Anyone can help maybe? Thanks! Andrea

Hello NAV guys, We are using NAV for some time. Right now we have some FS switches in the test and we noticed we can't read some of the stuff from switches like CPU, temperature or power. They have sent us _*Tem:1.3.6.1.4.1.52642.2.1.45.1.1.11.1.3 Power:1.3.6.1.4.1.52642.2.1.45.1.1.6.1.3*_ Is there a way we can add these values to NAV so the system can read these values for CPU, temerature etc. Could not find it on the documentation, maybe missed it.

Update link in documentation

Received the following: "Just letting you know that you have an outdated link here - https://nav.uit.no/doc/reference/geomap.html It?s to the Firebug download page which is now defunct - http://getfirebug.com/ We?ve put together a list of our 10 favorite javascript debugging tools (essentially a list of alternatives to Firebug!), perhaps you could point people to this? Here?s the link - https://www.pcwdld.com/firebug-alternatives-javascript-debugg ing-tools Should prove useful for anyone missing Firebug! " Guess this should be fixed in the main branch. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø
