SNMPV3

[user54119]

I will try it with a support case at the vendor of the APs.

Another problem on other SNMP enabled nodes:
Suddenly no SNMP data is possible to poll. But the SNMP agent on these nodes are fine (test by snmpwalk on command line).
When I restart netxmsd everything is fine again. It's also with SNMPv3.

[user54119]

I found a hint about this problem in the local log file of the affected node. There is a system protection function which blocks the SNMP get requests from the NetXMS server because of requests with null community string (CVE-1999-0517). In the communication settings of this NetXMS node there are valid SNMPv3 credentials of course.
So maybe this problem has the same reason as the 'SNMP auth. failures'.

There has been a bunch of SNMP discovery fixes in the develop branch this weekend, any chance you can build from develop and try if issues still persist?

Hi Tomas

I normaly compile from 'official' sources (at the moment V2.0-RC2) on Linux, but I have never built from develop branch.
Do you mean compiling only the server from sources from hourly Snapshot of GIT repository?

Thanks
Dani

Yes, you can compile from the hourly snapshot of GIT repo and test with that.
The fixes were mostly to snmp in relation to agent proxying and to snmp discovery, but maybe you will see some difference.

If none of these help (so your issue is still present after testing these newest changes), we will know yours is a totally separate issue.

The develop branch is pretty stable at the moment (I run 2 medium sized installs ~150 nodes each on it atm.), but of course be advised that it is not released code and consider backups of db/server before deploying it

Thanks Tomas.

I tried to compile hourly snapshot from git repo. But I get this error:

autoconf, flex, bison, libtool are installed.
What can I do?

Script, which generate this header require git repo, not a snapshot. It's a bug.
However, if you clone repo instead of using snapshot – it will work.
Repository url for clone is https://git.netxms.org/public/netxms.git

P.S. don't forget to switch branch to "develop" (git checkout develop)

[alk]

I've fixed that, now snapshots should work as well

[user54119]

Thanks Alex for the fast fix

Now downloading the snapshot from download site on website, './reconf', 'configure...', 'make',... works!

[user54119]

The SNMP_AUTH_FAILURE events are gone!
For the other problems I need more time to test.

thanks for the fixes
Dani

Is the also a solution for this topic

https://www.netxms.org/forum/configuration/snmp-credentials/

im still hesitant to upgrade to 2.0 because i really dont want to have to reset over 200 switches  due to the  wrong community string being sent out repeatedly

[user54119]

In my opinion I would say yes! (11h of test)
