Different responses from command line than from library about node-net-snmp HOT 5 CLOSED

Hi @maufc,

So it looks like the large integer in the OID is not being parsed correctly.

Are you able to provide a packet trace of the query and response so I can troubleshoot it further?

Thanks

Hi. I'm sorry I couldn't answer before.
I couldn't provide the packet Trace of the query or the response. If you can tell me how to do it I will.
Could it be dice on some other way?
Thanks

So it looks like you are on a Lunix host, in which case do something like (untested):

tcpdump -w capture.cap -i any port 161

Recreate the issue, then attach the resulting capture.cap file.

Hi.
Sorry for the late response...
According to this, I do get an answer from the device but I still get an error on the command line.
This is the capture:
19:06:53.676674 IP generador-NUC7i3BNH.46454 > 153.0.0.140.snmp: GetRequest(37) E:28634.6.3607365907.2.8198.0

This is the response on command line:

Hope you understand where the problem is.

Thanks!
