Re: Trying to run tutorial example

Thank you!

I have managed to make it working.
The tutorial in
http://net-snmp.sourceforge.net/wiki/index.php/TUT:Writing_a_Subagent
helped me a lot,
Yet, the following 2 things helped me make it working:
1. upgrade from 5.6.2 to 5.7.3
2. add agentx in configure
  --with-mib-modules="agentx"
3. add debug capability on running snmpd:
   snmpd -f -Lo: -Dagentx

I would add step2 in that tutorial.... It really took time to find the issues.

Thanks,
ranran
