And the only thing i can see on NetXMS server is this

Where do i need to dig to find something more?

Victor Kirhenshtein

How did you compile agent for Pi? Can you send me config.h from your build? I suspect wrong byte order detection.

Best regards,
Victor

nihplod

tried
sudo sh configure --with-agent
and
sudo sh configure --with-agent --libdir=/usr/lib

Cause there was first some lib errors, but that was solved with the libdir i think. I also moved all the libs to /usr/lib that was for nxagent first compile also cause it wasn't looking in /usr/local/lib apparently.

attached config.h, the output from configure, the output from make and the output from make install

Any idea about what i could do about this?

Victor Kirhenshtein

You can try to rebuild agent with --disable-iconv option. If this will not help, can you consider giving me shell access to it so I can debug the issue?

Best regards,
Victor

I tried to rebuild it with that flag but it seems i have the same issue.

I sent you logindata and stuff for the unit.
Just use sudo for root stuff. Dont break the small baby

Hi!

Just try to connect to agent via ssh port forwarding - it responds correctly. I see in your config that you turn on authentication on agent - but do you enter correct authentication parameters in node properties? Currently everything is correct in my test:

C:\Source\NetXMS\x64\debug>nxget -e 0 -p 4444 -a sha1 -s <secret> 127.0.0.1 Agent.Version
1.2.1

and on the agent:

Yeah, it seems that it wont work when i have authentication running.
I have the same configuration as the other nodes and it will just halt when doing a poll, but if i comment out the authentication it will work. And i am using the very same settings that i've done for the other nodes that has working auth.

Thanks for the help tho

Victor Kirhenshtein

Can you show me screenshot of authentication properties in console for this node? nxget works fine with authentication, so server should also work.

Best regards,

I have tried with None, Plain text, md5 and sha1. But when i remove encryption from configuration file and restarts it works properly.

This is the result when i try accessing with the client using any setting when having force encryption activated on the node

But do you build agent with encryption enabled? I remember that on some stage of debugging you was rebuilding it without encryption.

nihplod

It is built with --disable-iconv now, that is the only disable i have. Encryption isn't that important for me on my own private network at home. I can communicate with the node so it's not an issue now ^^
