Problems with PING subagent after update to V2.2.1

[user54119]

no, nothing like this in the agent log. Not in normal log and not in debuglog.
In debuglog I see lines like this:

I can send you a debuglog of the pinging agent if that helps. But I can't share it in the forum

[Sviests]

Could you, please, provide the output of "nxagentd -C"? Don`t forget to edit out any sensitive data, I am interested specifically in the PING subtree.

[user54119]

here the output of the agent on the NetXMS server itself (linux). I had to change a few sensitive data and removed some of the ping targets...
If you need the unchanged output, you can give me another communication channel.

Could you try changing the PING subagent section in config to uppercase? As in:

*PING
DefaultPacketSize = 46
...

[user54119]

I changed "[ping]" to "[PING]", but no change in problem.

I have all agent config files and policies in INI-style, the sections like this:

[ping]
...

is it necessairy to change to "*PING"-style? I couldn't see anything about that in changelog.

[Sviests]

It shouldn`t change anything, it was just a guess :).
Could you let me know which Linux distribution you are using, what kernel etc... Also, which version of Windows?

[user54119]

There are a few different systems and OS. All tests for this troubleshooting here I made on 2systems:

1. Windows 2012 R2 english with all current patches
2. SuSE Linux, kernel 3.12.67

Same problems on both of them

Hi,

we just fixed this bug. If you are building from sources, you can just re-build agent from current "stable-2.2" branch in our repository or replace file src/agent/subagents/ping/ping.cpp with attached one in your current source tree and rebuild. I'll also repack Windows installers.

Best regards,
Victor

ping.cpp

Hi Victor

I just replaced the ping.cpp in the src and recompiled the agent on linux. That fixed the problem! Thank you Victor!

Can you please inform, when you have rebuilt the windows agent packages. Then I can replace the other agents with PING subagent in use.

thanks
Dani

[user54119]

Hi Victor

Do you have an ETA for the patched Windows agent binary?

thanks
Dani

[victor]

Hi,

here you can download patched Windows agents: https://netxms.org/download/patches/019/

Best regards,
Victor

[user54119]

Hi Victor

Thank you for the patched versions. I already tested on Win2012R2 and Win10. Success!
I will deploy it now to the other devices where PING subagent is used.
