How to add sensorgateway probes to nav ?
by FOUR Ludovic (EXT) 17 Des '21

17 Des '21

Hello, I'm using NAV 5.2 and I would like to add a couple of Serverscheck temperature probes that monitor our network racks Product reference is detailed here : https://serverscheck.com/sensors/baseunit.asp I'm trying to add the probes by following the adding AKCP probe tutorial. I made this : 1/ Translate the sensorgateway.mib into SERVERSCHECK-MIB.py with smidump command 2/ Copy the python file to folder /opt/venvs/nav/lib/python3.7/site-packages/nav/smidumps There's a ServersCheck module used in MIB file, that i'm using to interrogate directly the probe I can get the temperature value with snmpwalk -c community -v1|2c <IP of the probe> ServersCheck:sensor1Name.0 If I translate into OID with snmptranslate command, I get this OID .1.3.6.1.4.1.17095.3.2.0 3/ Create the file serverscheck_mib.py with those lines to /opt/venvs/nav/lib/python3.7/site-packages/nav/mibs from twisted.internet import defer from nav.mibs import reduce_index from nav.mibs.mibretriever import MibRetriever from nav.smidumps import get_mib class ServerCheckMib(MibRetriever): mib = get_mib('SERVERSCHECK-MIB') @defer.inlineCallbacks def get_all_sensors(self): result = [ { 'oid': '.1.3.6.1.4.1.17095.3.2.0', 'unit_of_measurement': 'celsius', 'precision': 1, 'scale': None, 'description': "Ambient temperature", 'name': "Ambient temperature", 'internal_name': "Ambient temperature", 'mib': 'SERVERSCHECK-MIB', } ] defer.returnValue(result) - Add the following lines to /etc/nav/ipdevpoll.conf (note sure of iana code of serverscheck manufacturer. should be 25432) 25432 = ServersCheckMib SERVERSCHECK = SERVERSCHECK-MIB At this point i'm stuck (ipdevpoll log empty) and I still can't get sensors readings into NAV and it doesn't recognize the probe type into collected info of the seedDB probe page Any ideas of what I'm doing wrong ?

advice on upgrading nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11
by Mischa Diehm 10 Des '21

10 Des '21

Hei all, we have a larger NAV setup with a bit more than 1000 Cisco Switches and use quite a lot of the features supported in NAV. Since our setup is a bit dusty we plan to upgrade (nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11). I wanted to ask for your advice on the upgrade paths possible. We use a external db server that hosts the postgres db. Requirements/Whishes: - it would be great to keep the devices history and graphs so a simple dump.py and reinstall would be a bit lossy - it would be nice to start with a fresh installed debian 11. Is there a good/preferred path that we could follow? Thanks for any ideas and suggestions, Mischa p.s.: Any ideas / timeframe when nav will release debian 11 packages? -- narrowin.ch /\ network & security

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

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.

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?
