This is the error that I got when I try to use snmpfwd to convert from v1 to v2c ...

Below I copied the configuration file used during this test.

Could you help me any how ?

Thank you for your report!

It would be helpful if you could re-run the crashing tool with debugging enabled (--debug-snmp=msgproc,secmod,io,dsp) and attach the debugging output to this issue.

To help you, this is the command line that I am using to send the trap ...

sudo snmptrap -v1 -c XXXX 127.0.0.1:1234 1.3.6.1.4.1.20408.4.1.1.2 127.0.0.1 6 432 12345 1.3.6.1.2.1.1.1.0 s 'my system'

Thanks for your help on that ...

You can pip install right from GitHub repo. Or download .zip and install it locally. Or clone (or fork->clone) the repo and install from there.
